Signatures of fractional electronic charge observed in topological insulators

The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions of electronic charge are not normally encountered. Despite this, researchers at the University of Illinois at Urbana-Champaign have recently observed the signature of fractional charges ranging from e/4 to 2e/3 in exotic materials known as topological crystalline insulators.

2020 'Dead Zone' may remain four times larger than the goal established in 2001

A recent forecast of the size of the "Dead Zone" in the northern Gulf of Mexico for late July 2020 is that it will cover 7,769 square-miles of the bottom of the continental shelf off Louisiana and Texas. The coronavirus pandemic has had no impact on the Gulf of Mexico dead zone. The unusually high Mississippi River discharge in May controls the size of this zone, which will likely be the 7th largest zone since systematic measurements began in 1985. The water mass with oxygen concentrations less than 2 parts per million forms in bottom waters each year primarily as a result of nitrogen and phosphorus loading from the Mississippi River watershed, which fertilizes the Gulf of Mexico's surface waters to create excessive amounts of algal biomass. The decomposition of this plant material in the bottom layer leads to oxygen loss.

Buoy oh buoy! Floating instruments receive major upgrade

A PNNL research team has upgraded the instrumentation on two lidar buoys used to capture data that help advance the scientific understanding of offshore wind and its energy-producing potential. The buoys were equipped with more powerful lidars that reach up to 200 meters, providing a higher data recovery rate. Previously, the lidar beams did not consistently return data at heights above 90 meters, and thus did not satisfy the data needs for today's much taller wind turbines.

New 'sun clock' quantifies extreme space weather switch on/off

Extreme space weather events can significantly impact systems such as satellites, communications systems, power distribution and aviation. They are driven by solar activity which is known to have an irregular but roughly 11 year cycle. By devising a new, regular 'sun clock', researchers have found that the switch on and off of periods of high solar activity is quite sharp, and are able to determine the switch on/off times. Their analysis shows that whilst extreme events can happen at any time, they are much less likely to occur in the quiet interval.

Closer to a heat battery: Understanding the atomistic processes

Salts are cheap and sustainable materials that can be used to store energy (heat) over periods ranging from hours to years without loss. This works via so-called hydration-dehydration processes. Energy release (discharge) occurs when a salt incorporates water molecules in its crystal structure (hydration). Energy is stored in the reverse process (dehydration), when water molecules are driven out of the crystal lattice with help of available heat. Power input and output are important characteristics of an energy storage device. Therefore, the kinetics of the hydration and dehydration process needs to be understood.

Cellular stress causes cancer cell chemoresistance

There is a broad range of mechanisms associated with chemoresistance, many of which to date are only poorly understood. The so-called cellular stress response—a set of genetic programs that enable the cells to survive under stressful conditions—plays a key role in the development of numerous diseases and in chemoresistance. A better understanding of the cellular stress response pathways is therefore urgently required to develop new therapeutic concepts to overcome chemoresistance. "In this context, we employed comprehensive analytical approaches to gain deep and molecular insight into the Unfolded Protein Response, a cellular stress reaction induced by unfolded proteins," says Robert Ahrends, group leader at the Department of Analytical Chemistry of the Faculty of Chemistry.

Simulations on biologically relevant time scales achieved

Molecular dynamics simulations (MD) have become a ubiquitous tool in modern life sciences. In these simulations, the interactions between atoms and molecules and their resulting spatial movements are iteratively calculated and analyzed. Scientists are currently trying to gain access to biologically relevant length and time scales using this approach in order to describe molecular processes such as protein folding and protein-drug binding, which are crucial for, for example modern drug development. A team led by Dr. Steffen Wolf and Prof. Dr. Gerhard Stock from the Biomolecular Dynamics group at the Institute of Physics of the University of Freiburg has now succeeded in predicting the dynamics of binding and unbinding processes on a time scale of seconds to half a minute in pharmacologically relevant test systems. The results have been presented in the current issue of the journal Nature Communications.

Roadkill study identifies animals most at risk in Europe

Around 194 million birds and 29 million mammals are thought to be killed each year on European roads, according to a new study that has ranked the most vulnerable species.An international research team used 90 roadkill surveys from 24 European countries to create a new method of estimating both the birds and mammal species killed most often on roads, and the species most vulnerable to being wiped out of certain areas.The research, published in Frontiers in Ecology and Environment, found that the species killed most often were not necessarily the ones most vulnerable to disappearing completely. This means action to preserve wildlife when new roads are built risks being targeted at the wrong species based on current methods.

Scientists reveal relationship between Dek and Intron retention during muscle stem cells quiescence

Muscle stem cells, the reserve stem cell in the skeletal muscles, are responsible for muscle repair after damage. They are the 'regenerative medicine' to cure muscle diseases and muscle damage. In a healthy uninjured condition, muscle stem cells are in quiescence, a dormant state, to preserve them. Whenever there is muscle damage, they will wake up instantly and contribute themselves to building new muscles.

How COVID-19 has altered sleep in the United States and Europe

Stay-at-home orders and "lockdowns" related to the COVID-19 pandemic have had a major impact on the daily lives of people around the world and that includes the way that people sleep, two studies report June 10 in the journal Current Biology. Both studies show that relaxed school and work schedules and more time spent at home has led people to sleep more on average with less "social jetlag" as indicated by a reduced shift in sleep timing and duration on work days versus free days. But, at the same time, one of the studies also finds that the pandemic has taken a toll when it comes to self-reported sleep quality.

Potent tetrahydroquinolone can eliminate parasites that cause toxoplasmosis and malaria

Toxoplasma gondii infection is one of the most frequent parasitic infections of humans.

Microneedling therapeutic stem cells into damaged tissues

Mesenchymal stem cells (MSCs) are multipotent in that they naturally replenish the cell types that build bone, cartilage and adipose tissues. However, they exhibit much broader regenerative potential, including their capacity to migrate and engraft in injured tissues and secrete factors that enhance the formation of new blood vessels, suppress inflammation and cell death, and promote healing. These characteristics make them exquisite candidates for cell-based therapies for diseases as varied as cardiovascular, liver, bone and cartilage diseases, lung and spinal cord injuries, autoimmune diseases and even cancer and skin lesions.

Kidneys deteriorate with age, regardless of health

An international study carried out on nearly 3000 people in Norway, Germany and Iceland shows that human kidney function deteriorates with age regardless of the presence of other diseases. The results from the study have recently been published in the Journal of the American Society of Nephrology (JASN). To discover how kidney function progresses, the researchers examined the kidney function of a group of people between the ages of 50 and 70, and two groups of people between the ages of 70 to 95.

Researchers forecast stable, slightly declining levels of COVID-19 entering fall

The rate in which COVID-19 cases spread is not proportionate with the number of contagious individuals—as prior models assumed—but rather concave, meaning that the impact of one more infected person diminishes as more people are infected. The disproportionate spread occurs because people typically live and work in inter-related social networks, meaning people stay in the same circles, according to researchers at Washington University in St. Louis.

New recommendations on genetic testing for prostate cancer

Prostate cancer is a leading cause of death from cancer in the US and especially in the Philadelphia region. Consistently, Philadelphia has outpaced the state of PA and the nation in diagnoses and death from prostate cancer. A key area impacting prostate cancer risk and treatment is germline genetic testing, which involves testing for hereditary cancer genes. Genes such as BRCA2, BRCA1 and many other genes have been reported to raise the risk for prostate cancer and are increasingly informing treatment and management approaches. However, genetic testing of men for prostate cancer is still not common practice due to inconsistent guidelines and challenges to implementation of genetic counseling.

Study suggests Baboon model could aide in Alzheimer's disease interventions

Scientists at Texas Biomedical Research Institute's (Texas Biomed) Southwest National Primate Research Center (SNPRC) recently published findings indicating the baboon could prove to be a relevant model to test therapeutics and interventions for neurodegenerative diseases, such as early stage Alzheimer's and related dementias. The scientists observed a steep age-related cognitive decline in baboons about 20-years-old, which is the equivalent of a 60-year-old human. The team of scientists, led by Dr. Marcel Daadi, Associate Professor at Texas Biomed's SNPRC, published their findings in the May issue of Aging . These studies are a first step in developing the baboon as an appropriate animal model for early stage Alzheimer's disease.

A good vitamin D status can protect against cancer

A good vitamin D status is beneficial both in cancer prevention and in the prognosis of several cancers, according to a new research review. The anti-cancer effects of vitamin D are especially pronounced in the prevention and treatment of colon cancer and blood cancers. In addition, high vitamin D responsiveness can be linked to a smaller cancer risk. Vitamin D responsiveness varies between individuals, affecting their need for vitamin D supplementation.

Flu vaccine coverage linked to reduced antibiotic prescribing

Up to 76 percent of all outpatient antibiotic prescriptions in the United States may be inappropriate, with peak prescribing associated with the flu season. Evidence suggests that influenza vaccines may reduce overall and inappropriate antibiotic use by reducing the burden of influenza-like illness commonly mistreated with antibiotics, as well as preventing secondary bacterial infections. While flu vaccines have been proven to reduce severe illness, evidence is lacking on the link between flu vaccination and antibiotic prescribing at the population level in the US.

Glycolysis involved in immunosuppression by polyphenol

Known as the French paradox, a low incidence of coronary heart disease despite substantial intake of saturated fats is thought to be due to a diet rich in polyphenols.

Coronavirus and asthma: what we know so far

When the new coronavirus arrived in early 2020, people with asthma were identified as being at higher risk from the disease. Judgements about who was at increased risk had to be made on the best available evidence—which wasn't much. Data from China was only just emerging and COVID-19 had yet to reach pandemic status.

We're not all equal in the face of the coronavirus

Are there differences in immunity to the SARS-CoV-2 coronavirus between populations from different geographic regions? Part of the answer to this question is to be found in the genomes of these groups of people, specifically in the HLA genes responsible for the adaptive immune system. These genes are special in that they often differ between individuals. Thousands of possible variants (or alleles) have been identified, and not all of them are equally effective in fighting a new virus. The frequency of these alleles varies from one population to another due to past migrations and their adaptation to different environments. In a study to be published in the journal HLA, scientists from the University of Geneva (UNIGE) – working in collaboration with the Max Planck Institute in Jena (Germany) and the University of Adelaide (Australia) – have pinpointed the HLA variants that are potentially the most effective against seven viruses, including the new coronavirus. They have also brought to light significant differences between populations.

Although most of those at high medical and financial risk were white, racial minorities were over-represented.

Immunodominant epitopes identified for designing peptide-based vaccine against SARS-CoV-2

There are currently no licensed vaccines available for COVID-19. While several antiviral drugs have been tested, none has proved to be completely effective against the disease. In a study just published in the journal MDPI Vaccines, researchers from Bar-Ilan University have identified a set of potential immunodominant epitopes from the SARS-CoV-2 proteome. These epitopes are capable of generating both antibody- and cell-mediated immune responses. The findings of this work may thus contribute to developing a peptide vaccine against SARS-CoV-2 infections which can stop the COVID-19 outbreak and future pandemics caused by coronaviruses.
