Study Reveals Why Large Groups of Humans Are Hopeless in a Crisis
During a crisis, psychologists have found people are less likely to take action during an emergency if there are others around them. Oftentimes, members of a community experience denial, or do not believe the threat is real to them, leaving action until the last moment.
The globalpandemicand the current climate crisis have shown us that reaching consensus in large groups takes a lot of convincing, especially when there's a sharp conflict of views.
Compared to a simulation, however, the stakes for inaction in reality are a lot higher - so it's good to keep this human shortcoming in mind.
The few preliminary clinical studies that have been done with stem cells and exosomes don't support commercialising these interventions, let alone justify their use in the current pandemic.
Stem cells are an interesting treatment avenue for coronavirus, no doubt, but they have not yet proved effective under well-designed and rigorously conducted clinical trials.
As astudyshowed last year, the downstream effects can be surprising, and far-reaching too, affecting much more than just yourdental wellbeing.
In an experiment led by scientists from the UK and Spain, researchers found that the simple act of using mouthwash after exercising can reduce one of the benefits of exercise:lowering blood pressure.
When you exercise, your blood vessels open in response to the production ofnitric oxide, which increases the diameter of blood vessels. This process is calledvasodilation, and it increases blood flow circulation to active muscles.
For a long time, researchers thought this only happened during exercise, but in more recent years, evidence has shown that circulation stays high (meaning blood pressure is lowered) even after exercise – thanks to how bacteria interact with a compound called nitrate, which forms when nitric oxide degrades.
Research unveils patterns in brain activity associated with intergroup conflicts
This study is among the first to investigate the synchronization of neural activity within groups in relation to individual and group-level decision-making.
the first to uncover brain-to-brain coupling at the level of larger groups, and crucially, to show that this neural synchronization predicts collective decision making. Their work could open up new horizons for future studies exploring how social interactions can shape brain activity and how these socially shaped neural patterns can in turn drive collective actions.
This his work reveals how individuals in already established groups interact and make group decisions. We also collected new data regarding the formation of group, to reveal the neural mechanism of how single individuals form a group. In our next studies, we are interested in exploring the influence of group structure (such as peer group, leader-follower etc.) on intergroup interaction.

Class of stellar explosions found to be galactic producers of lithium
Classical novae
The formation of the universe, commonly referred to as the "Big Bang," primarily formed the elements hydrogen, helium and a little lithium. All the other chemical elements, including the majority of lithium, are formed instars.
Classical novae are a class of stars consisting of a white dwarf (a stellar remnant with the mass of the sun but the size of Earth) and a larger star in close orbit around the white dwarf.
Gas falls from the larger star onto the white dwarf, and when enough gas has accumulated on the white dwarf, an explosion, or nova, occurs. There are about 50 explosions per year in our galaxy and the brightest ones in the night sky are observed by astronomers worldwide.

Terahertz radiation can disrupt proteins in living cells
Terahertz radiation is a portion of the electromagnetic spectrum between microwaves and infrared light, which is often known as the "terahertz gap" because of the current lack of technology to manipulate it efficiently. Because terahertz radiation is stopped by liquids and is non-ionizing—meaning that it does not damage DNA in the way that X-rays do—work is ongoing to put it to use in areas such as airport baggage inspections. It has generally been considered to be safe for use in tissues. However, some recent studies have found that it may have some direct effect on DNA, though it has little ability to actually penetrate into tissues, meaning that this effect would only be on surface skin cells.
"It was quite interesting for us to see that terahertz radiation can have an effect on proteins inside cells without killing them cells themselves. We will be interested in looking for potential applications in cancer and other diseases."

Searching for new sources of matter–antimatter symmetry breaking in Higgs boson interaction with top quarks
When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and parity symmetry) – was considered to be exact until 1964, when a study of the kaon particle system led to the discovery of CP violation.
CP violation is an essential feature of our universe. The imbalance between matter and antimatter, which led to the present-day universe, is a consequence of CP-violating processes that occurred just moments after the Big Bang. However, the size of CP violation, observed so far exclusively in theweak interaction, is insufficient to account for the present matter–antimatter imbalance. New sources of CP violation must therefore exist.
The discovery of the Higgs boson has opened up opportunities for physicists to search for these new sources of CP violation. The ATLAS Collaboration at CERN has performed a direct test of the CP properties of the interaction between the Higgs boson and top quarks.The resultis based on an analysis of the full Run-2 dataset from the Large Hadron Collider (LHC), looking at collision events where the Higgs boson is produced in association with one or two top quarks, and decays into two photons. Asimilar analysishas been recently released by the CMS Collaboration.

There are two types of burping, but mainly we burp to get rid of swallowed air from our stomach.
There aretwo typesof burping. The first is known as gastric burping, which comes from your stomach. It is the most common type of burp.
Gastric burping is a normal way our body gets rid of swallowed air. We may not realise it, but every time we swallow food, around atablespoon worth of airalso enters our stomach.
Eventually, this buildup of air stretches the stomach and causes both the valves to relax at both thetopandbottomof your food pipe.
For the air that escapes upwards from your stomach, your muscleshelp to push the air out. These muscles are in a part of your body called your “diaphragm”, and also the muscles at the front of your tummy, which you might call your “abs” or “six-pack”.
These muscles push the air up your oesophagus and then out of your mouth (or sometimes your nose!).

Excited delirium: How debatable excuses can be used to defend some cases of police brutality
Excited (or agitated) delirium is characterized by agitation, aggression, acute distress and sudden death, often in the pre-hospital care setting. It is typically associated with the use of drugs that alter dopamine processing, hyperthermia, and, most notably, sometimes with death of the affected person in the custody of law enforcement. Subjects typically die from cardiopulmonary arrest, although the cause is debated. Unfortunately an adequate treatment plan has yet to be established, in part due to the fact that most patients die before hospital arrival. While there is still much to be discovered about the pathophysiology and treatment, it is hoped that this extensive review will provide both police and medical personnel with the information necessary to recognize and respond appropriately to excited delirium.
What is ‘excited delirium’?
Excited delirium is a controversial diagnosis, often used when people die in police custody.
Whether it actually exists is debated among experts and police forces alike, but people with excited delirium are said to be aggressive and incoherent, with “superhuman strength” imbued by their taking stimulant drugs such as cocaine.
Critics of the term have dismissed it as pseudo-science, a convenient excuse used to justify excessive police force
Critics argue that it’s not a legitimate cause of death, with police using it as an excuse when arrests involve avoidable deaths, and say the term is disproportionately cited in cases where black and Hispanic men die in custody.

Despite the popularity of spicy cuisine among Homo sapiens, the hotness in chili peppers has always been something of an evolutionary mystery.
A plant creates fruit in order to entice animals to eat and disperse its seeds, so it doesn't make sense for that fruit to be painfully hot, said University of Florida zoology professor and evolutionary ecologist Douglas Levey.
But according to new research by Levey and six colleagues from other universities, chilies have a very good reason to make themselves hot. It boils down to protection.
Based on research on wild chili plants in rural Bolivia, the scientists found that the leading cause of seed mortality is a fungus called Fusarium. The fungus invades the fruits through wounds made by insects and destroys the seeds before they can be eaten and dispersed.
Capsaicin, the chemical that makes the peppers hot, drastically slows microbial growth and protects the fruit from Fusarium. And while capsaicin deters local mammals, such as foxes and raccoons, from consuming the chilies, birds don't have the physiological machinery to detect the spicy chemical and continue to eat the peppers and disperse seeds, Levey said.
The researchers' findings will be released today in a paper published online by theProceedings of the National Academy of Sciences.
The term tear gas refers to a group of chemical irritants that can be used to control or disperse crowds. The chemicals that are used for this purpose cause irritation of mucous membranes and of the eyes including tearing (hence the name “tear gas”), twitching around the eyes, cough, difficulty breathing and irritation to the skin.
They arebelieved to be short-term irritantsand unlikely to kill or cause permanent harm, especially if delivered at relatively low levels, on a single occasion and in open spaces. At high levels in closed spaces, though, theycan be lethal.
The chemicals are solids, not gasses, but may be delivered dispersed as aerosols in pyrotechnic mixtures that disperse the chemical during the explosion or in solutions delivered as a spray. There are multiple tear gas chemicals, the most likely of which is called 2-chlorobenzalmalonitrile or CS, which was named forBen Corson and Roger Stoughton, American chemists who invented it in 1928. CS was adopted as the official militaryriot controlchemical in 1959. There have been many instances of tear gas use around the world.
However, there is little human data on specific vulnerable populations.
Is tear gas a chemical weapon?
The 1993 InternationalChemical Weapons Convention, Geneva banned tear gas from being used where military forces are at war. However, a number of countries, including the U.S., have approved the use of tear gas for civilian riot control and for crowd control of non-military persons.
Glacier mice: these herds ofmoss-ballsroam the ice – and we’re uncovering their mysteries
Glacier mice don’t appear on just any ice sheet – there are only a few glaciers worldwide where they can be found. In 2012, we travelled to one called Falljökull tostudy their movements.
We dissected some of these moss balls and inserted accelerometers. These devices measure movement, and are used to orient mobile phones so that if you rotate them, their displays turns accordingly. The data we collected from accelerometers helped crack the puzzle of how moss in contact with the ice can survive when other plants would usually die.
The glacier mice rotated often, at least once every few days. It is this rotation that enables the glacier mice to grow moss around the whole of their outer surfaces – sometimes creating near perfect spheres. If the glacier mice stopped rotating, the moss that comes into permanent contact with the glacier surface would die.
Glacier mice are often found teetering on icy pedestals, and that’s because each of these moss balls actually reduces the amount of melting that occurs underneath it. So over a period of hours and days, the glacier mouse becomes elevated on a pedestal of ice and it eventually rolls off.
This process repeats itself over and over, so that the ball exposes a different surface to the sun each time it falls. In time, this means the moss ball rotates often and evenly enough to prevent any part staying in contact with the ice too long.
Recent research onglacier mice in Alaskafound that glacier mice can live for more than six years in this pattern. But scientists still don’t know why groups of glacier mice tend tomove herd-likeon the ice surface, sometimes south, sometimes west, but always in concert with each other. Wind, gravity and melting patternsaren’t enoughto fully explain the mystery, so research continues.

Terahertz radiation can disrupt proteins in living cells
Terahertz radiation is a portion of the electromagnetic spectrum between microwaves and infrared light, which is often known as the "terahertz gap" because of the current lack of technology to manipulate it efficiently. Because terahertz radiation is stopped by liquids and is non-ionizing—meaning that it does not damage DNA in the way that X-rays do—work is ongoing to put it to use in areas such as airport baggage inspections. It has generally been considered to be safe for use in tissues. However, some recent studies have found that it may have some direct effect on DNA, though it has little ability to actually penetrate into tissues, meaning that this effect would only be on surface skin cells.
"It was quite interesting for us to see that terahertz radiation can have an effect on proteins inside cells without killing them cells themselves. We will be interested in looking for potential applications in cancer and other diseases."

Searching for new sources of matter–antimatter symmetry breaking in Higgs boson interaction with top quarks
When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and parity symmetry) – was considered to be exact until 1964, when a study of the kaon particle system led to the discovery of CP violation.
CP violation is an essential feature of our universe. The imbalance between matter and antimatter, which led to the present-day universe, is a consequence of CP-violating processes that occurred just moments after the Big Bang. However, the size of CP violation, observed so far exclusively in the weak interaction, is insufficient to account for the present matter–antimatter imbalance. New sources of CP violation must therefore exist.
The discovery of the Higgs boson has opened up opportunities for physicists to search for these new sources of CP violation. The ATLAS Collaboration at CERN has performed a direct test of the CP properties of the interaction between the Higgs boson and top quarks. The result is based on an analysis of the full Run-2 dataset from the Large Hadron Collider (LHC), looking at collision events where the Higgs boson is produced in association with one or two top quarks, and decays into two photons. A similar analysis has been recently released by the CMS Collaboration.

why do we burp?
There are two types of burping, but mainly we burp to get rid of swallowed air from our stomach.
There are two types of burping. The first is known as gastric burping, which comes from your stomach. It is the most common type of burp.
Gastric burping is a normal way our body gets rid of swallowed air. We may not realise it, but every time we swallow food, around a tablespoon worth of air also enters our stomach.
Eventually, this buildup of air stretches the stomach and causes both the valves to relax at both the top and bottom of your food pipe.
For the air that escapes upwards from your stomach, your muscles help to push the air out. These muscles are in a part of your body called your “diaphragm”, and also the muscles at the front of your tummy, which you might call your “abs” or “six-pack”.
These muscles push the air up your oesophagus and then out of your mouth (or sometimes your nose!).

Excited delirium: How debatable excuses can be used to defend some cases of police brutality
Excited (or agitated) delirium is characterized by agitation, aggression, acute distress and sudden death, often in the pre-hospital care setting. It is typically associated with the use of drugs that alter dopamine processing, hyperthermia, and, most notably, sometimes with death of the affected person in the custody of law enforcement. Subjects typically die from cardiopulmonary arrest, although the cause is debated. Unfortunately an adequate treatment plan has yet to be established, in part due to the fact that most patients die before hospital arrival. While there is still much to be discovered about the pathophysiology and treatment, it is hoped that this extensive review will provide both police and medical personnel with the information necessary to recognize and respond appropriately to excited delirium.
What is ‘excited delirium’?
Excited delirium is a controversial diagnosis, often used when people die in police custody.
Whether it actually exists is debated among experts and police forces alike, but people with excited delirium are said to be aggressive and incoherent, with “superhuman strength” imbued by their taking stimulant drugs such as cocaine.
Critics of the term have dismissed it as pseudo-science, a convenient excuse used to justify excessive police force
Critics argue that it’s not a legitimate cause of death, with police using it as an excuse when arrests involve avoidable deaths, and say the term is disproportionately cited in cases where black and Hispanic men die in custody.

Despite the popularity of spicy cuisine among Homo sapiens, the hotness in chili peppers has always been something of an evolutionary mystery.
A plant creates fruit in order to entice animals to eat and disperse its seeds, so it doesn't make sense for that fruit to be painfully hot, said University of Florida zoology professor and evolutionary ecologist Douglas Levey.
But according to new research by Levey and six colleagues from other universities, chilies have a very good reason to make themselves hot. It boils down to protection.
Based on research on wild chili plants in rural Bolivia, the scientists found that the leading cause of seed mortality is a fungus called Fusarium. The fungus invades the fruits through wounds made by insects and destroys the seeds before they can be eaten and dispersed.
Capsaicin, the chemical that makes the peppers hot, drastically slows microbial growth and protects the fruit from Fusarium. And while capsaicin deters local mammals, such as foxes and raccoons, from consuming the chilies, birds don't have the physiological machinery to detect the spicy chemical and continue to eat the peppers and disperse seeds, Levey said.
The researchers' findings will be released today in a paper published online by the Proceedings of the National Academy of Sciences.

Tear gas ....
https://theconversation.com/what-is-tear-gas-139958?utm_medium=emai...
The term tear gas refers to a group of chemical irritants that can be used to control or disperse crowds. The chemicals that are used for this purpose cause irritation of mucous membranes and of the eyes including tearing (hence the name “tear gas”), twitching around the eyes, cough, difficulty breathing and irritation to the skin.
They are believed to be short-term irritants and unlikely to kill or cause permanent harm, especially if delivered at relatively low levels, on a single occasion and in open spaces. At high levels in closed spaces, though, they can be lethal.
The chemicals are solids, not gasses, but may be delivered dispersed as aerosols in pyrotechnic mixtures that disperse the chemical during the explosion or in solutions delivered as a spray. There are multiple tear gas chemicals, the most likely of which is called 2-chlorobenzalmalonitrile or CS, which was named for Ben Corson and Roger Stoughton, American chemists who invented it in 1928. CS was adopted as the official military riot control chemical in 1959. There have been many instances of tear gas use around the world.
How does tear gas work?
These chemicals react with sensory nerve receptors that can cause pain and discomfort in skin, eyes and mucous membranes. They act almost instantly, but the irritation they induce is usually resolved in about 30 minutes to a....
Can tear gas cause permanent harm?
In low level and infrequent exposures, they are unlikely to cause permanent harm. They have been used for years by the military to train on gas mask use. There is some human evidence reported of long-term effects mainly from high dose exposures in indoor situations and for long time periods.
However, there is little human data on specific vulnerable populations.
Is tear gas a chemical weapon?
The 1993 International Chemical Weapons Convention, Geneva banned tear gas from being used where military forces are at war. However, a number of countries, including the U.S., have approved the use of tear gas for civilian riot control and for crowd control of non-military persons.

Glacier mice: these herds of moss-balls roam the ice – and we’re uncovering their mysteries
Glacier mice don’t appear on just any ice sheet – there are only a few glaciers worldwide where they can be found. In 2012, we travelled to one called Falljökull to study their movements.
We dissected some of these moss balls and inserted accelerometers. These devices measure movement, and are used to orient mobile phones so that if you rotate them, their displays turns accordingly. The data we collected from accelerometers helped crack the puzzle of how moss in contact with the ice can survive when other plants would usually die.
The glacier mice rotated often, at least once every few days. It is this rotation that enables the glacier mice to grow moss around the whole of their outer surfaces – sometimes creating near perfect spheres. If the glacier mice stopped rotating, the moss that comes into permanent contact with the glacier surface would die.
Glacier mice are often found teetering on icy pedestals, and that’s because each of these moss balls actually reduces the amount of melting that occurs underneath it. So over a period of hours and days, the glacier mouse becomes elevated on a pedestal of ice and it eventually rolls off.
This process repeats itself over and over, so that the ball exposes a different surface to the sun each time it falls. In time, this means the moss ball rotates often and evenly enough to prevent any part staying in contact with the ice too long.
Recent research on glacier mice in Alaska found that glacier mice can live for more than six years in this pattern. But scientists still don’t know why groups of glacier mice tend to move herd-like on the ice surface, sometimes south, sometimes west, but always in concert with each other. Wind, gravity and melting patterns aren’t enough to fully explain the mystery, so research continues.
