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,…
Researchers at the Francis Crick Institute have found that molecules in vegetables like broccoli or cauliflower help to maintain a healthy barrier in the lung and ease infection. The AHR — aryl hydrocarbon receptor — is a protein found at barrier sites like the gut and the lung. Natural molecules…
Neuroscientists at Scripps Research have identified brain circuits that make mammals want to eat more when they are exposed to cold temperatures. Mammals automatically burn more energy to maintain normal body temperature when exposed to cold. This cold-activated increase in energy expenditure triggers an increase in appetite and feeding, although…
Could plants be the answer to the looming threat of microplastic pollution? Scientists at UBC’s BioProducts Institute found that if you add tannins — natural plant compounds that make your mouth pucker if you bite into an unripe fruit — to a layer of wood dust, you can create a…
“Back-to-school” season means buying pens and paper, figuring out the new bus route, and … earaches. Doctors typically treat these infections with antibiotics, but children don’t always complete the full course, accelerating resistance to these medications. Today, researchers report developing a single-use nanoscale system that’s unlikely to generate resistance. Using…
SAN FRANCISCO, Aug. 15, 2023 — Aloe barbadensis, commonly known as aloe vera, has been used for thousands of years to treat skin ailments, promote digestive health and heal wounds. But while aloe vera gel is in high demand, the peels are thrown away as agricultural waste. Today, scientists report…
Young vegetables known as microgreens are reputed to be particularly good for health. Now, researchers are trying to find out if microgreens — which can easily be grown at home — are the superfood they’re claimed to be, and how they compare to mature veggies. Results to date show their…
Can you recognize someone you haven’t seen in years, but forget what you had for breakfast yesterday? Our brains constantly rearrange their circuitry to remember familiar faces or learn new skills, but the molecular basis of this process isn’t well understood. Today, scientists report that sulfate groups on complex sugar…
Indoor air pollution may have met its match. Today, scientists will report that they have designed catalyst-coated lampshades that transform indoor air pollutants into harmless compounds. The lampshades work with halogen and incandescent light bulbs, and the team is extending the technology so it will also be compatible with LEDs.…
A few years ago, amid lockdown boredom, it seemed like everyone was perfecting their sourdoughs. A simple, fermented mixture of flour and water, the bread is powered by microbes that provide its one-of-a-kind tangy flavor. For over a hundred years, sourdough bread has been synonymous with San Francisco, where today,…
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…
With Labor Day approaching, many people are preparing to go tubing and swimming at local streams and rivers. These delightful summertime activities seem innocuous, but do they have an impact on these waterways? Today, scientists report preliminary results from the first holistic study of this question, which shows that recreation…
Surgeons at NYU Langone Health have transplanted a genetically engineered pig kidney that continues to function well after 32 days in a man declared dead by neurologic criteria and maintained with a beating heart on ventilator support. This represents the longest period that a gene-edited pig kidney has functioned in…
A team of researchers have found a shared penchant for sewing reflective shell beds onto clothing and other items across three Indonesian islands that dates back to at least 12,000 years ago. The team, led by the Australian National University’s Professor Sue O’Connor with Griffith University’s Associate Professor Michelle Langley,…
Bats gather to feast as nocturnal insects fly through mountain passes in the Pyrenees each autumn, new research shows. University of Exeter scientists identified seven bat species and 66 insect species (90% of which were moths) in the Pass of Bujaruelo, near Spain’s border with France. The study shows that…
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…
Research is underway around the world to find alternatives to our current electronic computing technology, as great, electron-based systems have limitations. A new way of transmitting information is emerging from the field of magnonics: instead of electron exchange, the waves generated in magnetic media could be used for transmission, but…
Teeth could be capable of preserving antibodies for hundreds of years, allowing scientists to investigate the history of infectious human diseases, a new study has found. Antibodies are proteins produced by the immune system as a natural response to infectious organisms like viruses and bacteria. Their job is to recognise…
How well can we assess the strength of our own immune system? The answer is that we are surprisingly good at this! A study by Konstanz psychologist Stephanie Dimitroff examined how freshly vaccinated people assess the strength of their immune response to the respective pathogen. Participants’ self-assessments were compared with…
Tiny plastic particles can be found in the sea air even far from coasts, according to a study recently published in the journal Nature Communications. The microplastics come from partly unexpected sources. Microplastic particles are present in the marine atmosphere even in remote parts of the world. These tiny particles…
ETH Zurich Professor Ori Bar-Nur and his team grow muscle cells in the laboratory. In this case, they are mouse cells, but the researchers are also interested in human and cow cells. Promising applications resonate with both: human muscle tissue cultured in the lab could be used in surgery, while…
