A graduate student relied on the bus system to get to class. He wanted to understand why, despite arriving at the bus stop on time, he was sometimes late to class. He developed a tool that considers transportation variables weighed against how great a margin of error bus riders are willing to accept, which can also apply to getting a lunar rover to its destination, and with a high degree of...

Amazonia is closer to a catastrophic ecological tipping point than any time in the last 100,000 years, and human activity is the cause.

The colloidal diamond could make light waves as useful as electrons in computing, and hold promise for a host of other applications. Researchers have devised a new process for the reliable self-assembly of colloids in a diamond formation that could lead to cheap, scalable fabrication of such structures.

A new survey of six U.S. states has found that during the past two months, more people are wearing masks, vaccine uncertainty is on the rise, and many people are overestimating their risk of becoming seriously ill and dying from COVID-19.

In a new climate modeling study that looked at the impacts of accelerated ice melt from the Antarctic Ice Sheet (AIS) on future climate, a team of climate scientists reports that future ice-sheet melt is expected to have significant effects on global climate.

Analyzing anonymized patient medical records, researchers discovered that cholesterol-lowering statins reduced risk of severe COVID-19 infection, while lab experiments uncovered a cellular mechanism that helps explain why.

During pregnancy in mice, the billions of bacteria and other microbes that live in a mother's intestines regulate key metabolites, small molecules that are important for healthy fetal brain development, biologists report. Scientists had not known until now whether the maternal gut microbiota influenced brain development during critical prenatal periods.

In a new study of volcanic processes, scientists have demonstrated the role nanolites play in the creation of violent eruptions at otherwise 'calm' and predictable volcanoes. The study describes how nano-sized crystals (nanolites), 10,000 times smaller than the width of a human hair, can have a significant impact of the viscosity of erupting magma, resulting in previously unexplained and explosive...

A new ultra-affordable and accessible hearing aid made from open-source electronics could soon be available worldwide, according to a new study.

Research shows prenatal cannabis exposure may impact child behavior later in life.

New research has found that feeding cats one large meal a day may help control hunger better than feeding them several times a day.

Obstructive sleep apnea (OSA) affects more than one billion people worldwide. Evidence suggests OSA can alter the gut microbiome (GM) and may promote OSA-associated co-morbidities, including diabetes, hypertension and cognitive problems. Researchers have discovered how OSA-related sleep disturbances affect the gut microbiome in mice and how transplanting those gut bacteria into other mice can...

New research proposes that Alzheimer's disease may be driven by the overactivation of fructose made in the brain. The study outlined the hypothesis that Alzheimer's is a modern disease driven by changes in dietary lifestyle that has resulted in excessive fructose metabolism in the brain.

A new study of air pollution in the United Kingdom during the first 100 days of lockdown has revealed that while nitrogen oxide levels were cut by half, levels of sulfur dioxide increased by over 100 percent.

In a new study, researchers examined the association between a positive SARS-CoV-2 test during pregnancy and complications in mothers and their newborn babies. Almost two out of three pregnant women who tested positive for SARS-CoV-2 were asymptomatic and the researchers found no higher prevalence of complications during delivery or of ill-health in the neonates. However, preeclampsia was more...

Weighted blankets are a safe and effective intervention in the treatment of insomnia, according to researchers who found that insomnia patients with psychiatric disorders experienced reduced insomnia severity, improved sleep and less daytime sleepiness when sleeping with a weighted chain blanket.

Emerging use of Global Navigation Satellite System (GNSS) makes it possible to continuously measure shallow changes in elevation of Earth surface. A study now shows that the quality of these measurements may have improved significantly during the pandemic, at least at some stations. The results show which factors should be considered in the future when installing GPS antennas.

Researchers have built an interactome that includes the lung-epithelial cell host interactome integrated with a SARS-CoV-2 interactome. Applying network biology analysis tools to this human/SARS-CoV-2 interactome has revealed potential molecular mechanisms of pathogenesis for SARS-CoV-2, the virus responsible for the COVID-19 pandemic. The research identified 33 high-value SARS-CoV-2 therapeutic...

A new study is examining the Earth's carbon cycle in new depth, using diamonds as breadcrumbs of insight into some of Earth's deepest geologic mechanisms.

College students are under a lot of stress, even more so lately due to the COVID-19 pandemic. New research finds that college health courses could help students develop a more positive stress mindset.

Most of the wind available on land is too gentle to push commercial wind turbine blades, but now researchers have designed a kind of 'tiny wind turbine' that can scavenge wind energy from breezes as little as those created by a brisk walk. The method is a low-cost and efficient way of collecting light breezes as a micro-energy source.

The warmer it gets, the faster Antarctica loses ice - and much of it will then be gone forever. That's what a team of researchers has found out in their new study on how much warming the Antarctic Ice Sheet can survive.

Nanoscale vortices known as skyrmions can be created in many magnetic materials. For the first time, researchers have managed to create and identify antiferromagnetic skyrmions with a unique property: critical elements inside them are arranged in opposing directions. Scientists have succeeded in visualizing this phenomenon using neutron scattering.

Proper folding of extremely long chromosomal DNA molecules is crucial for the correct functioning of the cell. Scientists developed a groundbreaking method to map contact points between replicated DNA molecules, thereby elucidating how the genome is folded inside the nucleus of human cells.
