November 19, 2020, New York - Water is a ubiquitous liquid with many highly unique properties. The way it responds to changes in pressure and temperature can be completely different from other liquids that we know, and these properties are essential to many practical applications and particularly to life as we know it.
Researchers from Edith Cowan University (ECU) in Western Australia have found a simple way to analyse the effectiveness of exercise training that could one day be conducted easily at a local gym or physio.
Using vertical jumps as a test activity, the researchers could predict detailed information regarding technique and muscle activation patterns just through a relatively simple analysis of forces produced against the ground during the jump.
Fragrances - promising mystery, intrigue and forbidden thrills - are blended by master perfumers, their recipes kept secret. In a new study on the sense of smell, Weizmann Institute of Science researchers have managed to strip much of the mystery from even complex blends of odorants, not by uncovering their secret ingredients, but by recording and mapping how they are perceived. The scientists can now predict how any complex odorant will smell from its molecular structure alone.
Forensic science experts at Flinders University are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport.
The Flinders-led research, led by postdoctoral research associate Dr Jennifer Young, will developed a system to trace the source of dust on suspect articles to match a soil profile of a specific area or overseas country.
According to the current state of knowledge, there are no cases that have shown evidence of humans being infected with the novel coronavirus via the consumption of contaminated food. Nor has any reliable evidence being presented to date concerning transmission of the virus via contact with contaminated objects or contaminated surfaces - such as packaging - which would have led to subsequent infections in humans. Imported refrigerated or frozen food and its packaging that has been produced under unhygienic conditions in regions affected by SARS-CoV-2 could contain the virus.
We all react to stress in different ways. A sudden loud noise or flash of light can elicit different degrees of response from people, which indicates that some of us are more susceptible to the impact of stress than others.
Any event that causes stress is called a "stressor". Our bodies are equipped to handle acute exposure to stressors, but chronic exposure can result in mental disorders, e.g. anxiety and depression and even physical changes, e.g. cardiovascular alterations as seen in hypertension or stroke-disorders.
Researchers have identified a new druggable target for heart failure in neonates and infants, a condition for which there has been no specific treatment. Approximately 60 percent of children born with congenital heart abnormalities will develop overt heart failure within the first year of life. The progression of heart failure in these infants is often rapid, with a high frequency of fatalities.
A UC Davis Health pediatric team presented a powerful case series of three teenagers who had unexplained breathing problems during the COVID-19 pandemic. The series highlighted the similarities between e-cigarette, or vaping, product use-associated lung injury (EVALI) and COVID-19 symptoms and manifestations.
The antiviral drug remdesivir is not suggested for patients admitted to hospital with covid-19, regardless of how severely ill they are, because there is currently no evidence that it improves survival or the need for ventilation, say a WHO Guideline Development Group (GDG) panel of international experts in The BMJ today.
DALLAS - Nov. 19, 2020 - Pregnant women who test positive for COVID-19 and their newborn babies have a low risk of developing severe symptoms, according to a new study from UT Southwestern.
Dr Zi Yang MENG from Division of Physics and Astronomy, Faculty of Science, the University of Hong Kong (HKU), is pursuing a new paradigm of quantum material research that combines theory, computation and experiment in a coherent manner. Recently, he teamed up with Dr Wei LI from Beihang University, Professor Yang QI from Fudan University, Professor Weiqiang YU from Renmin University and Professor Jinsheng WEN from Nanjing University to untangle the puzzle of Nobel Prize-winning theory Kosterlitz-Thouless (KT) phase.
How do people experience time alone and time with others? Findings from a new Bar-Ilan University study reveal the intricacies of people's experiences in these basic social conditions.
The study used a unique approach of analyzing self-generated text from more than 1,700 participants who performed a sentence-completion task regarding their experience alone and their social experience when in the company of others. This approach shed light on people's perceptions when free to express themselves without being bound to specific questions.
It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called "photoelectrons". In materials research, so-called "Auger electrons" also play an important role - they can be emitted by atoms if an electron is first removed from one of the inner electron shells. But now scientists at TU Wien (Vienna) have succeeded in explaining a completely different type of electron emission, which can occur in carbon materials such as graphite.
The largest freshwater bacterium, Achromatium oxaliferum, is highly flexible in its requirements, as researchers led by the IGB have now discovered: It lives in places that differ extremely in environmental conditions such as hot springs and ice water. The bacterial strains from the different ecosystems do not differ in their gene content, but rather chose what to express. The adaptation is probably achieved by a process which is unique to these bacteria: only relevant genes are enriched in the genomes and transcribed, while others are archived in cell compartments.
