Metabolic diseases such as diabetes mellitus affect the concentration of glucose
in many body fluids, including saliva. The level of glucose in saliva, in turn,
has a direct impact on the composition of the microflora of the oral cavity,
which can increase the risk of developing dental diseases. There are significant
changes in the amount and composition of the microflora in the saliva of
overweight and obese patients in comparison with patients with normal weight.
Using various methods of analysis, microorganisms were identified with the
highest degree of correlation between their number and an increase in glucose
levels in saliva.

Deserts are sparsely populated arid lands with a harsh climate. However, many
species of flora and fauna in the process of evolution were able to surprisingly
adapt to these difficult living conditions. Desert-dwelling toads burrow into
the sand and hibernate for many months until the rains come. Then they wake up,
begin to feed, spawn and breed. Some desert animals have evolved to have
elongated ears or other features that help keep them cool. Other animals fully
satisfy their water needs through the food they consume. Over the past three
decades, the need to increase agricultural production to feed a growing world
population has placed increasing pressure on land and water resources.

Plastic recycling is the process of converting plastic waste into secondary raw
materials, energy, or products with certain consumer properties. However, at
present, the problem of processing waste polymer materials is becoming relevant
not only from the standpoint of environmental protection, but also due to the
fact that in the conditions of a shortage of polymer raw materials, plastic
waste becomes a powerful raw material and energy resource. The greatest
difficulties are associated with the processing and use of mixed waste. The
reason for this is the incompatibility of thermoplastics that are part of
household waste, which requires their step-by-step isolation.

Hooke's law was discovered in the 17th century by the Englishman Robert Hooke.
This discovery about the stretching of a spring is one of the laws of the theory
of elasticity and plays an important role in science and technology. The
formulation of this law is as follows: the elastic force that appears at the
moment of deformation of the body is proportional to the elongation of the body
and is directed opposite to the movement of the particles of this body relative
to other particles during deformation. It is known that the stiffness of a
spring depends on its shape, size and material from which this body is made.

Assessing the health of a coral reef without instruments, as they say, by eye,
is quite difficult. New technologies come to the aid of biologists. So,
recently, scientists gave artificial intelligence to listen to audio recordings
made by hydroacoustic equipment. The thing is that the "repertoire" of the
inhabitants of the reefs is quite diverse, but incomprehensible to the human
ear. Therefore, scientists at the University of Exeter trained artificial
intelligence to guess the “melodies” of sick and healthy reefs. “Coral reefs
face multiple threats, including climate change, so it is critical to monitor
their health and how conservation efforts are progressing.” This method is much
more practical and cheaper than traditional diagnostics involving experienced
divers.

Today, both the external conditions and the internal conditions of the
functioning of the organization are changing very quickly, which puts most
companies in front of the need to train personnel to work in new conditions.
Many organizations are faced with the need to find the most effective ways to
increase productivity and work efficiency. Training is designed to prepare staff
for the correct solution of a wider range of tasks and to ensure a high level of
efficiency in their work. At the same time, it allows not only to increase the
level of knowledge of employees and develop the required professional skills,
but also to form in them such a system of values and attitudes that
corresponds to today's realities and supports a market organizational strategy.

Today, metrology uses a cesium atomic clock based on the half-life of
radioactive cesium to accurately measure one second, but there is another method
of measuring time. This article tells us about a new method of measuring Second.
These are extremely narrow optical resonances in cold atoms or single trapped
ions which can be measured with high resolution. A laser locked to such a narrow
optical resonance could serve as a highly stable oscillator for an all-optical
atomic clock. Now to count optical frequencies of hundreds of terahertz are
using femtosecond-laser frequency combs which gives the ability to count optical
oscillations of more than 1015 cycles per second facilitates high-precision
optical spectroscopy, and has led to the construction of an all-optical atomic
clock.

of mistletoe berries and their properties. The researchers found that through
simple wet processing, viscin fibers that adhere both to themselves and to other
materials can be stretched into thin films or assembled into three-dimensional
structures.They believe that viscin can be used as a sealant for wounds or to
cover the skin. Viscin can stick to wood, leather or feathers, as well as to
various synthetic surfaces such as plastics, glass and metal alloys. I believe
that this chemical composition will perform well in the future.

Today I have read the article "New processing technique could make potatoes
healthier". The article deals with the experiment of scientists. The goal of
this experiment was to create healthier potatoes. There is a perception that
potato products are unhealthy because eating large amounts of some potato
products can cause blood sugar levels to rise quickly, which poses a risk for
people with diabetes or those looking to control body weight.That's why,
researchers have announced early trials of a new potato processing technology
designed to make our bodies digest potato starch more slowly. This method is not
intended to prevent the potato from being overcooked, but to slow down digestion
to avoid a rapid rise in blood sugar. The method showed good results and I
believe that in the future it will allow you to eat potatoes without worrying
about the consequences.

Clinical Pharmacy.
A clinical pharmacy is a branch of a pharmacy where clinical pharmacists provide
direct care to patients, which optimizes the use of medicines and promotes
health, well-being and disease prevention. Clinical pharmacists take care of
patients in all medical institutions, but the movement of clinical pharmacies
initially began in hospitals and clinics. Clinical pharmacists often work in
collaboration with doctors, paramedics, nurse practitioners, and other
healthcare professionals . Clinical pharmacists may enter into a formal joint
practice agreement with another healthcare provider, usually one or more
doctors, which allows pharmacists to prescribe medications and order laboratory
tests.

article deals with the study of scientists, the purpose of which was the
discovery of an anti-cancer molecule. Vitamin D3 has important biological
functions, including the maintenance of bone mineral density, but vitamin D3 is
also believed to have anti-cancer activity. Vitamin d3 analogs are being
actively researched, but they have led to unwanted side effects. Scientists
tested a large number of DNA aptamers, making a list of 11 representatives and
only 4 remained, one of which (Apt-7) was left for further study. Apt-7
performed well. And I believe that a DNA aptamer-based molecule could be a
promising lead candidate for anticancer therapy.

the open ocean. However, they were able to detect a regulatory network that
controls the accumulation of zinc in the cyanobacterium Synechococcus in the
ocean. It allows changes in the internal zinc level of the bacterium by more
than two orders of magnitude and depends on a zinc uptake regulator protein
(Zur) that can sense zinc and react accordingly. I believe that this discovery

Ethnopharmacology is a branch of medical science in which drugs used by isolated
or primitive people are investigated using modern scientific methods. In some
cases, chemicals with the desired pharmacological properties are released and
eventually become drugs with properties recognizable in a natural product. Many
of the drugs we rely on today, from aspirin to morphine and the anti-cancer drug
Taxol, were derived from plants. The cross-cultural study of medicines derived
from natural substances, such as plants and fungi, is known as
Ethnopharmacology. He also studies natural medicines derived from plants and
other substances that have traditionally been used by groups of people to treat
various human diseases.

Today I have read the article "Carbon capture takes sponge-like form with new
cost-effective method". The article tells about different ways to capture
carbon. An international team of scientists is using porous, sponge-like
materials that can trap carbon dioxide in their cavities while allowing other
gases, such as nitrogen, to pass through. These materials are made from sugar
and inexpensive alkali metal salts, so they are cheap enough for large-scale
deployment and are effective in limiting environmental damage from coal-fired
power plants. For the past 100 years, amine scrubbing has been the leading
carbon capture method. However, it was very costly. I believe that this method
will someday help to capture CO2 from the air, which will be very useful to the
world.

Graphite is an important carbon material with many applications. Now a growing
use of graphite is anodes in lithium-ion batteries, as well as important for the
production of Tesla electric vehicles. This article does not answer the original
question "can graphite be produced from coal?", but it shows that carbon has an
overwhelming tendency to exfoliate - similar to graphite, but with many
"defects" such as pentagons and heptagons, which quite naturally fit into the
grid. In general, carbon is a miracle element - you can create life, diamond,
graphite, buckyballs, nanotubes, graphene and much more. I learned about all
this in this wonderful article, which I advise you to read.

Subdiscipline of pharmacology.
Pharmacology deals with the study of drug interactions with living systems. It
includes three subdisciplines: pharmacodynamics, pharmacokinetics and
pharmacogenetics. Pharmacodynamics is one of the main branches of Pharmacology
that studies the features of the effect of drugs on the human and animal bodies.
This discipline focuses on both the pharmacological effects of drugs themselves
and the mechanisms of their development. Pharmacokinetics is a branch of
Pharmacology that studies the kinetic patterns of chemical and biological
processes occurring with a drug in the body of an animal or human.
Pharmacogenetics is the science of human genetic characteristics that affect
individual drug tolerance.

Today I have read the article "Miniproteins that can launch two-pronged attacks
on viral proteins". This article is about miniproteins. The fact is that the
rapid emergence of new strains of the SARS-CoV-2 virus has weakened the
protection provided by vaccines against COVID-19. For this case, scientists have
developed a new class of miniproteins that can block the entry of the virus into
our cells and stick the virions together, reducing their ability to infect.These
were mini-proteins that could bind to and block the spike protein on the surface
of the SARS-CoV-2 virus. The miniprotein was also found to be thermostable - it
can be stored for months at room temperature without deterioration. I believe
that these miniproteins will serve as a good protection for people from viruses.

Today I have read the article "Research paves the way for stronger alloys". The
article tells about the research that opened the way to more durable alloys. The
study used high-speed synchrotron X-ray tomography to "photograph" the changing
crystal structures in molten alloys as they cooled. The study showed that as the
aluminum-copper alloy cools, the process of solidification begins with the
formation of faceted dendrites, which are formed by layer-by-layer laying of
basic units with a size of only a micrometer. It also gave real insight into
what happens at the micro level when an alloy is cooled, and shows the shape of
the basic building blocks of crystals in molten alloys. I believe that the end
result of the researchers' work will be very useful both in industry and in
everyday life where stronger metals would be useful.

Community pharmacy
A community pharmacy is a place where a practicing pharmacist sells
pharmaceuticals and other health products or retails directly to the public,
independent of other health care providers. Community pharmacies are located in
both rural and urban settings. Representing a core aspect of many health care
delivery systems, the community pharmacy is generally known for its reliability,
availability, and trust. The functions of the public pharmacy are to provide
additional medical services to the population. These services may include health
screening, blood pressure monitoring, diabetes screening, weight loss programs,
or even substance abuse help.

Fish include aquatic cranial vertebrates characterized by the presence of gills
throughout the life cycle and paired limbs in the form of fins. Many species
spend part of their life in sea water and part in fresh water. Such fish are
forced to make long, several thousand kilometers, migrations to spawning or
feeding grounds. Many deep-sea and Antarctic fish produce antifreeze, and
therefore can live for a long time at negative water temperatures. Most fish are
cold-blooded: their body temperature is equal to the ambient temperature. Fish

A severe mental condition that occurs as a result of a single or repeated event
that has a super-powerful negative impact on the psyche of the individual. The
traumatic nature of the event is closely related to the feeling of helplessness
due to the inability to act effectively in a dangerous situation. In most cases,
it is the family that creates the most favorable conditions for integrating a
person with a disability into society and raising his or her status. The family
is one of the subsystems of the social space of a person with a disability. If a

Cats gnaw and tear catnip leaves, because this leads to the most effective
insect repellent due to the substances contained in the leaves. The leaves of
catnip and actinidia, equally beloved by cats, contain iridoids, substances that
repel pests from plants - in particular, nepetalactol and nepetalactone. When
cats tear or chew leaves, it results in a copious excretion of these substances,
and also affects their ratio in the leaves. When the researchers applied the
same mixture of iridoids that is produced when leaves are damaged on plastic
plates, the experimental cats actively reacted to the smell, licking and chewing
the plates, which indicates the instinctive nature of their interest in catnip -
the animals were attracted by the substances themselves, although there were no

by Guglielmo Frigo
In modern power systems, the integration of renewable energy sources relies on

professional resilience to the limit. Now it’s important that these positive
changes to patient care and pharmacy practice in response to COVID-19 are
retained and built upon. We must continue to improve patient experience whilst
protecting the future sustainability. These principles and priorities for
transformation are at a critical point in the evolution of health care. This is
the start of an important process requiring concerted action and collaboration
across all health care sectors from all key stakeholders. This will enable us to
jointly shape pharmacy practice, ensuring the profession’s fullest potential is
utilised to improve patient care and contribute to the sustainability. I can

Pharmacology divisions
Established in 1954, the Division of Clinical Pharmacology at The Johns Hopkins
University School of Medicine is one of the oldest in the world, and has a long
history of laboratory and clinical research, teaching, and service activities.
Areas of investigation range across the spectrum of pharmacology: identification
of promising drug targets; preclinical studies of lead compounds; modeling of
pharmacokinetic/pharmacodynamic relationships; studies of kinetics, metabolism,
safety and efficacy of drugs in humans; rational use of drugs in clinical
practice.
The Division enjoys productive research collaborations with numerous Departments
in the School of Medicine, the School of Public Health, and the School of Arts
and Sciences. Faculty in the Division are integral to the widely acclaimed and
emulated Graduate Training Program in Clinical Investigation, the first such PhD
program in the country. Throughout its history, and by means of its research and
teaching missions, Clinical Pharmacology has brought a clear molecular
perspective to the science of clinical investigation.

A compounding pharmacy
A compounding Pharmacy prepares compounded drugs, according to the prescription
of medical practitioners. These drugs may be a blend of ingredients, which are
included in the medicines in exact dosage and potency according to the needs of
patients. The aim of an approved compounding pharmacy is to offer premium
nutritional supplements and bio-identical hormone treatments for patients in the
form of capsules, tablets, lotions, and creams. These pharmacies will prepare
drugs by combining different active pharmaceutical-grade constituents, as
recommended by any registered and qualified healthcare practitioner, into exact
dosage and strength forms according to the individual needs of patients. Both
state and federal authorities control all compounding pharmacies.

Three primary disciplines of Pharmacy
The field of Pharmacy can generally be divided into three primary disciplines:
• Pharmaceutics.
• Medicinal chemistry and Pharmacognosy.
• Pharmacy practice.
Also known as a retail pharmacy, the community pharmacy is the most well known
type of pharmacy. It is this type that is most traditionally known as the
pharmacist or chemist shop.

Today I have read the article «New research reveals unexpected function for
basic DNA-based processes during chromosome folding». Researchers have shown
that the three-dimensional organization of chromosomes in the cell nucleus is
governed by mechanisms that reads genes (transcription) and copies chromosomes
(replication). They do this by limiting the progress of a protein complex called
cohesin, which slides along the chromosomal DNA, folding it into loops. These
findings are essential for understanding the function of a healthy cell. They
are also relevant in a medical perspective since folding is essential for
several cellular processes that protects chromosomes against disease-promoting
aberrations.

Medicines and health products
Medicinal product - a substance or mixture of substances of synthetic or natural
origin in the form of a dosage form (tablets, capsules, solutions, ointments,
etc.) used for the prevention, diagnosis and treatment of diseases. Before being
used in medical practice, medicinal products must undergo clinical trials and be
approved for use. Groups of drugs are combined according to the direction of
action or the expected effect. To achieve a therapeutic effect, drugs should be
used in the right amount (dose), after a certain period, for a certain time.
Health products are natural products made without the use of harmful substances
and chemical compounds. They help to relax and cleanse the body, affect
metabolic processes, heal and nourish the skin.

Internet pharmacy
Since about the year 2000, a growing number of internet pharmacies have been
established worldwide. Many of these pharmacies are similar to community
pharmacies, and in fact, many of them are actually operated by brick-and-mortar
community pharmacies that serve consumers online and those that walk in their
door. The primary difference is the method by which the medications are
requested and received. Some customers consider this to be more convenient and
private method rather than traveling to a community drugstore where another
customer might overhear about the drugs that they take. Internet pharmacies are
also recommended to some patients by their physicians if they are homebound.

The free-energy pricincipe means that each agent should minimize the entropy of
their sensory states. It looks logical and natural. The human brain tries to
achieve calmness. By this principle, the cognitive systems should predict the
future state and, based on this, tailor with high precision. To realize the
prediction, the Bayesian brain is defined in the paper. The theory is based on
computational approaches like Laplace method, Bayson theorem, Gaussian-Markov
theorem. The place of them is unclear for me now, so I need to do some research.

Title: "Conflict and Cognitive Control in the Brain"
The paper consists of assumptions about cognitive conflicts in the human brain.
There is an area of the brain with the name Prefrontal cortex (PFC). This part
is responsible for orchestration of actions in other parts of the brain. It
looks like prioritization. But for detection of cognitive conflicts the Anterior
Cingulate cortex (ACC) is responsible. This part sends a signal for PFC and the
second updates priorities of tasks.
The authors have a focus on experiments about how fast the reaction for
conflicts. By this approach, the authors found out that time to error response
is the same as successful.
Reading such papers I am thinking about how to aggregate my vision of robotics
architecture. The human brain is deep to understand and each component like ACC
will take a lot of time to realize in robotics.

robotics. By this theory, the robot should minimize the energy costs caused by
surprise. But anyway, all theories have rights to exist and must be considered.
The most complicated problem in attention is the cross-modal interaction. There
is an open question about how to resolve conflicts from different modalities. As

7. A Possibilistic Kalman Filter for the Reduction of the Final Measurement
Uncertainty, in Presence of Unknown Systematic Errors
by Harsha Vardhana Jetti and Simona Salicone
This article tells us about the special variant of a Kalman filter. A Kalman
filter is a concept that has been in existence for decades now and it is widely
used in numerous areas to provide a prediction of the system states as well as
the uncertainty associated with it. However, the basic version of the Kalman
filter can`t propagate uncertainty in a correct way when the variables are not
distributed normally or when there is a correlation in the measurements or when
there is a systematic error in the measurements. In this version of the Kalman
filter authors define a possibilistic Kalman filter using random-fuzzy variables
which not only considers and propagates both random and systematic contributions
to uncertainty, but also reduces the overall uncertainty associated with the
state predictions by compensating for the unknown residual systematic
contributions.

important breakthrough in the creation of customized mRNA vaccines for various
diseases and allows the production of inexpensive mRNA in large quantities.First
of all, vaccines teach cells how to make a protein that triggers the body's
immune response, allowing its natural defenses to recognize the invading
virus.Also, new vaccines that use biological processes do not allow precise
molecular design of mRNA,which limits their use in the creation of new vaccines
as options become available.I liked a method that could allow mRNA to be
injected directly instead of using lipid nanoparticles.

Today I have read the article "Modifying surfaces with polymer chains promotes
uniform drying of particle-containing liquids".It's about the coffee ring
strategy and creating a consistent drying pattern.I liked the method that, to
achieve consistent drying patterns, is to change the surfaces of the particles
using polymer chains so that they effectively repel each other, being strongly
attracted to the surface of the drop.There is also a phenomenon that occurs when
liquids containing particles, so-called dispersions, such as ink, paint or red
wine, dry out.Ring patterns are just as undesirable in technical processes as
when we spill coffee.

polycrystalline materials.Undoubtedly, the shift at the crystal-void boundary
can indeed influence how microstructures develop.Also common metals, ceramics

these materials are polycrystalline, separated by defects known as grain

5. Systematic Distortion Factor and Unrecognized Source of Uncertainties in
Nuclear Data Measurements and Evaluations
by Nikolay V. Kornilov, Vladimir G. Pronyaev and Steven M. Grimes
When measuring, we get not only some quantitative characteristic of a physical
quantity but also its uncertainty part. As a result of experiments, we can
calculate and systematize the measurement uncertainty. Recommendations for the
presentation of measurement uncertainty are given in metrology manuals: the
statistical and systematic components of the uncertainty should be explained,
evaluated and presented separately as measurement results. due to many factors,
including the human one, all measurements are largely subjective, which makes
the systematic distortion factor (SDF) a permanent guest of any experiment. SDF
can also be a physical effect that can only be ruled out by additional
measurements or analysis. For a set of measured data with the best estimate of
the true value, their differences beyond their uncertainties can be explained by
the presence of an unrecognized source of uncertainty (USU) in the data. The
article considers the introduction and consideration of USU when evaluating data
in cases where it is impossible to eliminate the SDF.

3. Development of a Toolchain for Automated Optical 3D Metrology Tasks
by Prakash Jamakatel, Maximilian Eberhardt and Florian Kerber
Today, production is characterized by a wide range of automated production
lines, which allows you to quickly set up mass production. At the same time,
there is a problem of more complex artificial high-precision production, where
it would be good to use robots, but due to mass automation, it is not
profitable. This article reviews the Robotic Operational System (ROS), which
allows you to use visual control to expand the basic range of applications of
robots, manipulators and CNC machines. The processing steps comprise several
consecutive tasks: CAD-based object registration, pose generation for
sensor-guided applications, trajectory generation for the robotic manipulator,
the execution of sensor-guided robotic processes, test and the evaluation of the
results. The main benefits of the ROS framework are readily applicable tools for
digital twin functionalities and established interfaces for various manipulator
systems. As a result, authors get that complex geometry can be automatically
reconstructed, and they outperformed a standard method used as a reference.
Hence, extensions to other vision-controlled applications seem to be feasible.

decreased rapidly during the first half-hour of warm-up and stabilized by 3
hours after turning on the equipment, so it can show us how much time they need
to warm-up equipment to optimize the measurement’s accuracy.

simulated gas consisting of 60% methane and 40% carbon dioxide by volume are
determined, comparing them with the properties of pure methane. The influence of
these properties on the characteristic flame phenomena of the premixed mixture
is shown. The results show a strong effect of carbon dioxide on combustion

landfill biogas and natural gas/biogas mixture combustion have been
investigated. CFD results show lower peak flame temperature and CO mole
fractions inside the combustor, as well as lower NOx emissions at the combustor
outlet for biogas compared to natural gas fuel. The presence of non-combustible
components in the biogas reduces the flame temperature and hence the NOx
emissions.

of the year. The calculation is done according to Klein’s days over all the
months of the year. These results allowed to validate the applicability of this
model in a climate other than the desert climate.

Title: "Enhanced prediction of solar radiation using NARX models with corrected
input vectors"
The main objective of this work is to analyze and configure appropriately the
input vectors to enhance the performance of NARX models to forecast solar
radiation one hour ahead. For that, databases from three cities of Mexico with
different climates were obtained. These databases consisted of hourly
measurements of the following variables: solar radiation, wind speed, relative
humidity, pressure, and temperature. Results showed that, in all three cases,
proper NARX models were produced even when using input vectors formed only with
solar radiation and temperature data.

Today I have read the article «Researchers working to recover rare-earth
elements and secure critical materials for clean energy technologies» that tells
us about state-of-the-art methods to shed light on chemical separations needed
to recover rare-earth elements and secure critical materials for clean energy
technologies. Bastnäsite deposits are rich in rare-earth metals but must be
mined and separated from unwanted minerals through chemical processes that are
not well understood. Greater efficiency offers cost-savings as well as benefits
to the environment by decreasing mining and carbon impacts. I will wait for news
on this topic.

Today I have read the article «Developing a block copolymer that could enable
safer, more stable batteries» that tells us about polymer materials that can
provide safer and more stable batteries. Polymers are promising electrolytes for
solid-state lithium batteries for their low cost, flexibility and
processibility, but performance needs to be improved. The team designed a block
copolymer that sandwiches a conductive core between rigid outer layers that
protect the "filling." The use-inspired design is nanoengineered to block
dendrites, lithium growths that could pierce electrolytes and damage batteries.
I will wait for news on this topic.

Today I have read the article "A closer look at the creation of a metamorphic
sole".When two of Earth's tectonic plates collide, the heavier plate is forced
underneath and back into the mantle in a process called subduction.During the
early stages of newly initiated subduction zones, the uppermost part of the
downward traveling plate can detach and accrete to the base of the overriding
(upper) plate.Later, these slices can be exposed at Earth's surface and are
known as metamorphic soles.The study concludes by outlining a three-step
sequence for the evolution of the metamorphic sole.Thanks to this article, we
will learn a little more about metamorphic soles.

Today I have read the article "Machine-learning algorithm automatically
classifies sleep stages of lab mice".Researchers have created a new artificial
intelligence program for automatically classifying the sleep stages of mice that
combines two popular machine learning methods.The use of this system for
automatically annotating data can significantly assist sleep researchers when
analyzing the results of their experiments.They combined two machine-learning
techniques, convolutional neural networks (CNN) and long short-term memory
(LSTM) recurrent neural networks to achieve accuracies that surpass those of the
best existing automatic methods.Тhis program can already speed up the work of
researchers in the field of sleep, which may lead to a much clearer
understanding of how sleep operates.

Today I have read the article "Sweetened and unsweetened coffee consumption
associated with lower death risk". The study authors found that during the
7-year follow up period, participants who drank any amount of unsweetened coffee
were 16 to 21% less likely to die than participants who did not drink coffee.
Results were inconclusive for participants who used artificial sweeteners in
their coffee. Based on these data, we can say that you do not need to exclude
coffee from your diet, but you need to be careful with some types of coffee.I
really liked this article and the fact that I learned a lot of new things.

participation and engagement, the Google Health team announced the launch of a
new Android app. Off the bat, the Google Health Studies app allows users to view
a list of open studies and review the inclusion criteria for each. The Google
Health Studies App is a clear counterpart to Apple's Research app, which it
launched to iOS. In my opinion, this application will help researchers better
understand the risk factors, the dynamics of transmission of some diseases.

Every living organism in our planet has the ability to self-learn. They learn
how to react situations using appropriate actions. But robots can`t self-learn
cuz people can`t recreate algorithms which using living organism.
A team of physicists at Leipzig University led by Professor Frank Cacho’s, in
collaboration with colleagues at Charles University Prague, have developed a
method for giving tiny artificial micro swimmers a certain ability to learn
using machine learning algorithms. The micro swimmers find their way through the
liquid while repeatedly being thrown off of their path, mainly by Brownian
motion. "Our results show that the best swimmer is not the one that is fastest,
but rather that there is an optimal speed," said Viktor Holubec, who worked on
the project as a fellow of the Alexander von Humboldt Foundation and has now
returned to the university in Prague.
I don`t know how to react to this news, cuz I watched all Terminator franchise,
and it`s no good for us.
