Skoltech scientists find a way to make pultrusion faster
A research team from the Skoltech Center for Design, Manufacturing and Materials (CDMM) studied the effects of processing additives - aluminum hydroxide and zinc stearate - on the polymerization kinetics of thermosets used in pultrusion.

Why hotter clocks are more accurate
A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping.This is the first time that a measurement has been made of the entropy - or heat loss - generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future technologies, as systems approach the quantum realm.

New innovation successfully treats neonatal hypothermia
Neonatal hypothermia -- which occurs when an infant's core body temperature falls below the normal range needed to maintain health -- contributes to approximately one million deaths each year, and countless cases of stunted growth, almost exclusively in low- and middle-income countries. To address this common but preventable condition, researchers from Boston Children's Hospital, engineers at Lawrence Berkeley National Laboratory, and colleagues in Rwanda developed the Dream Warmer, a low cost, reusable non-electric infant warmer to prevent and treat hypothermia.

Can federated learning save the world?
Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.

Damage to white matter is linked to worse cognitive outcomes after brain injury
A new University of Iowa study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury.

Losing an only child is more devastating than losing a spouse, according to study of Chinese parents
Which wound cuts deeper: the loss of an only child or loss of a spouse? A new study led by researchers at NYU Rory Meyers College of Nursing and Fudan University suggests that Chinese parents find the loss of an only child to be approximately 1.3 times as psychologically distressing than the loss of a spouse.

Why is COVID-19 so hard to treat? Growing evidence points to unique infectious profile
A comprehensive review into what we know about COVID-19 and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called "long-COVID". There is growing evidence that the virus infects both the upper and lower respiratory tracts - unlike "low" or "high" pathogenic" human coronavirus sub-species, which typically settle in one or the other.

Too much, too little or just right: WVU researchers study proper 'dosing' of telehealth
In a new project, WVU researchers completed a systematic review of studies that dealt with telehealth and chronic conditions. They found that--in general--telehealth services benefitted patients more if they continued for about a year, rather than ending after six months or so.

New study explores functionality in aquatic ecosystems
The functions of water-dominated ecosystems can be considerably influenced and changed by hydrological fluctuation. The varying states of redox-active substances are of crucial importance here. Researchers at the University of Bayreuth have discovered this, in cooperation with partners from the Universities of Tübingen and Bristol and the Helmholtz Centre for Environmental Research, Halle-Leipzig.

18.5 million year old vine fossil identified as new species
An 18.5 million-year-old fossil found in Panama provides evidence of a new species and is the oldest reliable example of a climbing woody vine known as a liana from the soapberry family. The discovery sheds light on the evolution of climbing plants.

Overcoming tab overload
A research team at Carnegie Mellon University recently completed the first in-depth study of browser tabs in more than a decade. They found that many people struggle with tab overload, an underlying reason being that while tabs serve a variety of functions, they often do so poorly.

Migratory songbirds climb to extreme altitudes during daytime
Great reed warblers normally migrate by night during its month-long migration from northern Europe to Sub-Saharan Africa. However, researchers have now discovered that during the few occasions when it continues to fly during daytime, it flies at extremely high altitudes (up to 6300 meters). One possible explanation for this unexpected and consistent behaviour could be that the birds want to avoid overheating. The study is published in Science.

Consumption of pornography is widespread among young Internet users
A new survey shows that websites dedicated to pornography are popular among 16- and 17-year-olds. But social media are playing also a prominent role.

How bullying and obesity can affect girls' and boys' mental health
Depressive symptoms are more common in teenage girls than in their male peers. However, boys' mental health appears to be affected more if they suffer from obesity. Irrespective of gender, bullying is a considerably greater risk factor than overweight for developing depressive symptoms. These conclusions are drawn by researchers at Uppsala University who monitored adolescents for six years in a questionnaire study, now published in the Journal of Public Health.

Breaching the blood-brain barrier to deliver precious payloads
RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven't been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of ultrasound and RNA-loaded nanoparticles can temporarily open the protective blood-brain barrier, allowing the delivery of potent medicine to brain tumors.

Study finds racial disparities in concussion symptom knowledge among college athletes
Among collegiate football players and other athletes, Black athletes recognize fewer concussion-related symptoms than their White counterparts, reports a study in the May/June issue of the Journal of Head Trauma Rehabilitation (JHTR). The official journal of the Brain Injury Association of America, JHTR is published in the Lippincott portfolio by Wolters Kluwer.

In the spotlight: Successful synthesis of perovskite visible-light-absorbing semiconductor material
Narrow-gap semiconductors with the ability to use visible light have garnered significant interest thanks to their versatility. Now, scientists in Japan have developed and characterized a new semiconductor material for application in process components stimulated by light. The findings have, for the first time, suggested a new way to reduce the band gap in cheaper and non-toxic tin-based oxide semiconductors for efficient light-based applications.

With bacteria against coral bleaching
Coral bleaching, which is becoming stronger and more frequent due to heat stress, has already wiped out corals at many locations globally. With the help of a microbiome-targeting strategy developed by an international team led by GEOMAR Helmholtz Centre for Ocean Research Kiel, it could become feasible to help protect corals from heat stress.
