An archaeological strategy adapted for space used daily photos to reveal how astronauts actually use areas aboard the International Space Station – and how this differs from intended uses. Justin Walsh of Chapman University, California, and colleagues present these findings in the open-access journal PLOS ONE on August 7, 2024. More than 270 people from 23 countries have visited the International Space Station (ISS) over more than two decades. Crew member interviews can reveal how people adapt to a novel environment—one featuring isolation, confinement, and microgravity—that is far removed ...

Researchers have developed an inexpensive bandage that uses an electric field to promote healing in chronic wounds. In animal testing, wounds that were treated with these electric bandages healed 30% faster than wounds treated with conventional bandages. Chronic wounds are open wounds that heal slowly, if they heal at all. For example, sores that occur in some patients with diabetes are chronic wounds. These wounds are particularly problematic because they often recur after treatment and significantly increase the risk of amputation and death. One of the challenges associated ...

A new study published in Science Advances reveals how early mammals grew and developed during their pivotal Jurassic radiation. Using a technique called synchrotron X-ray tomography to image growth rings in fossilised tooth roots, the researchers were able to estimate lifespans, growth rates, and even the timing of sexual maturity in these ancient creatures.  “This is the first time we've been able to reconstruct the growth patterns of these early mammals in such detail,” said Dr Elis Newham, a Postdoctoral Research Associate ...

By Leah Shaffer Researchers at Wash U have spent the better part of the decade studying the ins and outs of how locusts smell, including how odors affect the insect’s behavior. In research recently published in eLife, Barani Raman, a professor of biomedical engineering at the McKelvey School of Engineering, starts to map out just how olfactory circuits are altered in driving different behavior in locusts. Neuromodulator serotonin is a key factor in triggering how locusts can go from being a “loner” to “gregarious” — otherwise known as swarming ...

Pain management is an important component of caring for adults with cerebral palsy.  However, it's the least understood comorbidity in the adult cerebral palsy population.  A study led by Mark Peterson, Ph.D., M.S., FACSM, a professor of physical medicine and rehabilitation at University of Michigan Health, found that adults living with cerebral palsy had a very high occurrence of pain, with 90% having a pain history and 74% having multiple diagnoses of pain coming from different origins such as the lower back, irritable bowels, joint arthritis and chronic ...

Scientists at UCL have discovered a novel role played by ribosomes during the folding of new proteins in cells, described in their paper in Nature. Ribosomes, the cell’s dedicated molecular machines for protein synthesis, make all proteins in life and do so by piecing together one amino acid building block at a time. As they are being synthesised, these nascent proteins simultaneously attempt to fold while still associated to their parent ribosome, referred to as co-translational protein folding. Understanding how exactly ...

ITHACA, N.Y. – A new Cornell University study that tracks how many asthma-related emergency room visits result from pollen in metropolitan areas highlights the importance of knowing local plants and the need for developing science-based pollen forecasts. Such forecasts could alert vulnerable individuals on days when they should consider staying indoors or taking allergy medications ahead of time. “Even though the percent of asthma-related emergency department visits associated with pollen overall was only a few percent on an annual basis, ...

An often-overlooked component of natural and human-driven disasters is their potential to affect plant health and thus food security at domestic and international scales. Most disasters have indirect effects on plant health through factors such as disruptions to supply chains and damaged infrastructure, but there is also the potential for direct effects from disasters, such as pathogen or vector dispersal caused by floods, hurricanes, and human migration. These occurrences are rarely isolated and instead often occur simultaneously. We have seen examples of the concurrence of disasters in recent history through events such as market disruptions ...

Cold Spring Harbor Laboratory (CSHL) has begun to unravel a mystery millennia in the making. Our story begins 9,000 years ago. It was then that maize was first domesticated in the Mexican lowlands. Some 5,000 years later, the crop crossed with a species from the Mexican highlands called teosinte mexicana. This resulted in cold adaptability. From here, corn spread across the continent, giving rise to the vegetable that is now such a big part of our diets. But how did it adapt so quickly? What biological mechanisms allowed the highland crop’s traits to take hold? Today, a potential answer emerges. CSHL Professor and HHMI Investigator Rob Martienssen had ...

Scientists at the University of Southampton have answered one of the most puzzling questions in plate tectonics: how and why ‘stable’ parts of continents gradually rise to form some of the planet’s greatest topographic features. They have found that when tectonic plates break apart, powerful waves are triggered deep within the Earth that can cause continental surfaces to rise by over a kilometre. Their findings help resolve a long-standing mystery about the dynamic forces that shape and connect some of the Earth’s most ...
