Can children recognize sick faces?

According to the World Health Organization, globally, infectious disease is a leading cause of death among children. Furthermore, children are more likely than adults to contract infectious illnesses. However, there’s a gap in research measuring children’s responses to sick faces. It is important to understand how children’s ability to recognize and avoid sickness emerges and develops to help improve children’s health and public health more broadly. Previous research has only reported that adults can use faces to recognize if someone is sick and make judgments about whether to approach or avoid them. Researchers from the University ...

Are you breaking your body clock?

Researchers are using mathematical models to better understand the effects of disruptions like daylight savings time, working night shifts, jet lag or even late-night phone scrolling on the body’s circadian rhythms. The University of Waterloo and the University of Oxford researchers have developed a new model to help scientists better understand the resilience of the brain’s master clock: the cluster of neurons in the brain that coordinates the body’s other internal rhythms. They also hope to suggest ...

Nauseous territory: outfoxing predators using baits that make them barf

Introduced foxes, dogs, cats, rats, and other predators kill millions of native animals every year, but what if they were conditioned to associate this prey with food that made them ill? A team of international researchers have shown the potential to do just that, burying baits containing capsules of levamisole, a chemical that induces nausea and vomiting when consumed by predators. In a world first experiment conducted in south-eastern Australia, where introduced red foxes are responsible for countless wildlife deaths, the Australian National University (ANU) and University of South Australia scientists laid baits of fried deboned chicken, with some containing ...

Smartphone app may support drinkers who overindulge to drink less heavily

Access to a smartphone alcohol intervention app helped university students to cut down their overall alcohol consumption and the number of days they drank heavily, suggests a study published in The BMJ today. Unhealthy drinking is the biggest risk factor to health for 15 to 49-year olds, and unhealthy use of alcohol is especially prevalent among adult students, prompting the authors to design a smartphone app to encourage healthier drinking among this group. The authors tested the app in 1770 university students who had screened positive for ...

The modern sea spider had started to diversify by the Jurassic, study finds

An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind. These fossils are very important to understand the evolution of sea spiders. They show that the diversity of sea spiders that still exist today had already started to form by the Jurassic. Lead author Dr Romain Sabroux from the University of Bristol’s School of Earth Sciences, said: “Sea spiders (Pycnogonida), are a group of marine animals that is overall very poorly studied. “However, ...

CCNY scientists trap light inside a magnet

A new study led by Vinod M. Menon and his group at the City College of New York shows that trapping light inside magnetic materials may dramatically enhance their intrinsic properties. Strong optical responses of magnets are important for the development of magnetic lasers and magneto-optical memory devices, as well as for emerging quantum transduction applications. In their new article in Nature, Menon and his team report the properties of a layered magnet that hosts strongly bound excitons -- quasiparticles with particularly strong optical interactions. Because of that, the material is capable of trapping light -- all by itself. As their experiments ...

Schizophrenia genetic risk factor impairs mitochondrial function

Researchers at Rutgers and Emory University are gaining insights into how schizophrenia develops by studying the strongest-known genetic risk factor. When a small portion of Chromosome 3 is missing – known as 3q29 deletion syndrome – it increases the risk for schizophrenia by about 40 fold. Researchers have now analyzed overlapping patterns of altered gene activity in two models of 3q29 deletion syndrome, including mice where the deletion has been engineered in using CRIPSR, and human brain organoids, or three-dimensional tissue cultures used to study disease. These two systems both exhibit impaired mitochondrial ...

New leaf-tailed gecko from Madagascar is a master of disguise

Leaf-tailed geckos are masters of camouflage. Some species have skin flaps around the whole body and head, as well as flattened tails. During the day, they rest head-down on tree trunks with these skin flaps spread out, and blend seamlessly into their surroundings, making them nearly impossible to spot. At night, they awaken to prowl the fine branches of the understory looking for invertebrate prey. “When we first discovered this species in 2000, we already suspected it might be new to science,” says Dr Frank Glaw, curator of herpetology at the Bavarian State Collection of Zoology, lead author on the study. “But ...

Collecting clean water from fog

In countries such as Peru, Bolivia and Chile, it’s not uncommon for people who live in foggy areas to hang up nets to catch droplets of water. The same is true of Morocco and Oman. These droplets then trickle down the mesh and are collected to provide water for drinking, cooking and washing. As much as several hundred litres of water can be harvested daily using a fog net only a few square metres in area. For regions with little rain or spring water, but where fog is a common occurrence, this can be a blessing. One crucial drawback with this method, however, ...

Cleaning water with ‘smart rust’ and magnets (video)

SAN FRANCISCO, Aug. 16, 2023 — Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles they call “smart rust” that actually makes it cleaner. Smart rust can attract many substances, including oil, nano- and microplastics, as well as the herbicide glyphosate, depending on the particles’ coating. And because the nanoparticles are magnetic, they can easily be removed from water with a magnet along with the pollutants. Now, the team is reporting that they’ve ...

Harnessing big data reveals birds’ coexisting tactics

Birds likely hold smart insights about coexisting in popular habitats– especially as climate change looms. But tapping into that knowledge has a big hurdle: knowing where and how numerous birds live successfully in vast environments. In today’s biological research journal Proceedings of the Royal Society B, scientists at Michigan State University (MSU) peeled back layer upon layer of big data to tease out real-life answers that until now have been explored mostly in small-scale experiments. Sam Ayebare, a PhD candidate from Uganda, has led the work that is the first steps to understanding how so many birds can coexist in the vast Albertine ...
