New understanding of how proteins operate
A ground-breaking discovery by Centenary Institute scientists has provided new understanding as to the nature of proteins and how they exist and operate in the human body.

Seabirds' response to abrupt climate change transformed sub-Antarctic island ecosystems
A 14,000-year paleoecological reconstruction of the sub-Antarctic islands done by an international research team including HKU has found that seabird establishment occurred during a period of regional cooling 5,000 years ago. Their populations, in turn, shifted the Falkland Island ecosystem through the deposit of high concentrations of guano that helped nourish tussac, produce peat and increase th

Social media can guide public pandemic policy: QUT research
As global cases of COVID-19 fast approach 50 million, a team of Australian, Afghan, Iranian and Italian researchers examined more than 35,000 tweets and say social media analytics can capture the attitudes and perceptions of the public during a pandemic. They also suggest social media is now the best way to encourage people to follow measures and restrictions which have, in turn, triggered an incr

Early big-game hunters of the Americas were female, researchers suggest
For centuries, historians and scientists mostly agreed that when early human groups sought food, men hunted and women gathered. Not so, say researchers.

Analysis reveals high burden of musculoskeletal disorders across the globe
Musculoskeletal disorders — which affect muscles, tendons, ligaments, bones, and joints — can severely affect individuals' physical and mental health, and they're especially prevalent among aging adults. Although many researchers are studying these conditions and their rates in different regions of the world, no study to date has provided an overview of the burden of all musculoskeletal disorder

Variety in the migratory behavior of blackcaps
Many species of birds have always migrated south in the fall to spend the winter there, including the small blackcap, which often weighs only a few grams and yet covers thousands of kilometers. However, changes in our landscapes and climate change are not leaving migratory birds unaffected. They change their behavior, the destinations of their journey, the time of their departure or even the decis

Scientists assess saltwater intrusion into well water along the Rhode Island coastline
Many drinking water wells at homes along the Rhode Island coastline are being contaminated by an intrusion of saltwater, and as sea levels rise and storm surge increases as a result of the changing climate, many more wells are likely to be at risk. So a team of University of Rhode Island researchers is conducting a series of geophysical tests to determine the extent of the problem.

Farmer ants could teach us a thing or two
Ants have been farmers for tens of millions of years—and a new study shows they might have overcome key domestication challenges that humans have yet to solve. Fungus-farming ants are an insect lineage that relies on farmed fungus for survival. In return for tending to their fungal crops—protecting them against pests and pathogens and providing them with both stable growth conditions in undergrou

Researchers urge healthcare providers to routinely ask patients about cannabis use
Healthcare providers should talk to patients about their cannabis use the same way they talk about other habits like smoking and drinking: routinely and without judgment. Marian Wilson, lead author on a new paper about shared decision-making in talking about cannabis use, says some studies have suggested cannabis use is beneficial to patients with chronic pain who are also using opioids, which is

The ebb and flow of brain ventricles
Enlarged ventricles in the brains of people with multiple sclerosis were previously considered a sign of tissue loss. But a team at the MDC and ECRC demonstrated that this expansion often recedes. A study published in JCI Insight now shows that the process observed in mice is transferable to humans.

Noise reduction via intermittent control by utilizing a plasma actuator
A research team at Toyohashi University of Technology developed a method for reducing aerodynamic noise via plasma. Cavity flow, such as the flow around car gaps of high-speed trains, often radiates aerodynamic noise. A plasma actuator inducing flow was applied to suppress this noise. By periodically switching off the power of the plasma actuator, a higher reduction in sound pressure level was obs

Rare ancient child burial reveals 8,000-year-old secrets of the dead

Stanford engineers have developed a genetic microlab that can detect COVID-19 in minutes
The microlab test takes advantage of the fact that coronaviruses like SARS-COV-2, the virus that causes COVID-19, leaves behind tiny genetic fingerprints wherever they go in the form of strands of RNA, the genetic precursor of DNA. If the coronavirus's RNA is present in a swab sample, the person from whom the sample was taken is infected.

Dense microgel suspensions reveal in-silico what happens under compression
Microgel suspensions made up of microscopic liquid-filled polymer particles occupy a curious physical state somewhere between liquid and solid, giving them unique properties and potential uses in self-healing structures, optically active materials, microreactors, drug-delivery systems, and templates for regenerating living structures such as bone and muscle.

Många vinster med att variera mera i jordbruket
Mer variation på åkrarna och i odlingslandskapet gynnar för det mesta både ekosystemtjänster och biologisk mångfald – utan att äventyra skörden. Det visar en internationell studie som letts av forskare från SLU. Diversifieringen av jordbruket kan ske både ovan och under jord, till exempel genom att man odlar fler grödor i växtföljden, sår blomremsor, minskar jordbearbetningen, tillsätter stallgöd

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma
