Laptops and schoolwork on kitchen tables, a deserted playground, face masks on a washing line, an empty church, a walk in the woods. As the UK Covid inquiry continues for a fifth week, researchers at the University of East Anglia have created a unique snapshot of lockdown life. When the pandemic first hit, the team embarked on a project to track the physical and mental health of the nation. More than a thousand participants signed up and up and they were followed every day for three months in the first study of its kind. As well as keeping daily lifestyle diaries about their physical activity, diet and mood, ...

Heliconius butterflies’ brains grew as they adopted a novel foraging behaviour, scientists at the University of Bristol have found. A region of their brain, known as the mushroom body due to its shape, are two to four times larger than those of their close relatives. The findings, published today in Nature Communications, suggest that the structure and function of the nervous system are closely linked to an organism's ecological niche and behaviour. Dr Stephen Montgomery of Bristol’s School of Biological Sciences explained: “Heliconius are the only butterflies known to collect and digest pollen, which gives them an adult source ...

New Haven, Conn. — While pembrolizumab is an approved treatment for patients with stage III non-small cell lung cancer (NSCLC), only some patients respond to this therapy. Treatment failure, researchers say, is often caused by differences in the tumor microenvironment. An ongoing phase II study (KEYNOTE-495/KeyImPaCT) led by a researcher at Yale Cancer Center reveals that combining pembrolizumab with other treatments reduced the size of target tumors, resulting in a higher response rate for patients with advanced NSCLC. The new research was published July 10 in Nature Medicine. “We are excited to share these new ...

Every night, uncounted numbers of devices across the globe update their operating systems (OS), and everyday users log on expecting fast, secure connections and services to keep their increasingly online lives moving forward. But as artificial intelligence and other more complex systems come online, the foundation of all them is teetering. Every aspect of society — from government and industry to education and entertainment — relies on devices with stable operating systems. And every OS relies on ...

Imagine you just swallowed a pill containing a miniature camera that will help your doctor collect images to diagnose a condition you’ve been battling for years. No, it’s not something from the latest science fiction or Marvel Comics movie – it’s a technique called bioimaging. While traditional methods of bioimaging such as an MRI, CT scan, or an X-ray are more commonly known, the use of nanodevices is becoming more popular. They are less invasive and provide health care professionals with a closer look deep inside tissue. Researchers from Virginia Tech’s College of Engineering and College of Science are using their expertise ...

As utility-scale solar farms become more widespread as a source of renewable energy, Virginia Tech scientists are researching environmental consequences with respect to stormwater and the sediment and nutrients transported in runoff. With a $3.4 million grant from the Virginia Department of Environmental Quality, researchers from the College of Agriculture and Life Sciences will lead a comprehensive six-year study to determine how utility-scale solar farms impact stormwater runoff and local soil and water quality throughout the state. “Solar is probably going to be the No. 1 land use change that will occur over the next decade in many parts of Virginia, particularly in existing ...

Papillary craniopharyngiomas (PCPs) are a rare type of brain tumor that cause substantial morbidity for patients. While surgery and radiation are often used to treat PCPs, incomplete removal of the tumor and toxicity from radiation can leave patients with life-long health challenges after treatment, including neuroendocrine dysfunction or vision or memory loss. Investigators from the Mass General Cancer Center, a member of the Mass General Brigham healthcare system, led the first multicenter treatment protocol in this rare tumor. The study was based on laboratory discoveries by Mass General Brigham researchers who studied the genetic drivers of PCP growth, ...

A groundbreaking study published today reveals the critical yet severely understudied factor of salinity changes in ocean and coastlines caused by climate change.

Ice Age saber-tooth cats and dire wolves experienced a high incidence of bone disease in their joints, according to a study published July 12, 2023 in the open-access journal PLOS ONE by Hugo Schmökel of Evidensia Academy, Sweden and colleagues. Osteochondrosis is a developmental bone disease known to affect the joints of vertebrates, including humans and various domesticated species. However, the disease is not documented thoroughly in wild species, and published cases are quite rare. In this study, Schmökel and colleagues identify signs of this disease in fossil limb bones of Ice Age saber-tooth cats (Smilodon fatalis) ...

A new mathematical model of UK cat populations suggests that neutering of cats that belong to people not only affects the population dynamics of owned cats, but also affects feral, stray, and shelter subpopulations. Jenni McDonald of Cats Protection and co-authors present these findings in the open-access journal PLOS ONE on July 12. More than ten million cats live as owned pets in UK homes, and hundreds of thousands of additional cats live in shelters or as free-roaming feral or stray cats. Cats may transition from any of these subpopulations to another. However, while many prior studies have investigated cat population ...

Prosthetic limbs are the most common solution to replace a lost extremity. However, they are hard to control and often unreliable with only a couple of movements available. Remnant muscles in the residual limb are the preferred source of control for bionic hands. This is because patients can contract muscles at will, and the electrical activity generated by the contractions can be used to tell the prosthetic hand what to do, for instance, open or close. A major problem at higher amputation levels, such as above the elbow, is that not many muscles remain to command the many robotic joints needed to truly restore the function of an arm and hand. A multidisciplinary team of surgeons and engineers ...

On the Moon, there are raw materials that humanity could one day mine and use. Various space agencies, such as the European Space Agency (ESA), are already planning missions to better explore Earth’s satellite and find minerals. This calls for appropriate exploration vehicles. Swiss researchers led by ETH Zurich are now pursuing the idea of sending not just one solitary rover on an exploration tour, but rather an entire team of vehicles and flying devices that complement each other. The researchers equipped three ANYmal – a type of legged robot developed ...

COLUMBUS, Ohio – For the first time, researchers have developed a model to estimate how much energy the original colonizers of New Zealand expended to maintain their body temperatures on the cold, harrowing ocean journey from Southeast Asia.   Results showed that people making the first voyages from Tahiti to New Zealand in sailing canoes would expend 3.3 to 4.8 times more energy on thermoregulation – the technical term for maintaining body temperature - than those making a trip of similar length to Hawaii.   The ocean route to New Zealand required much more energy for thermoregulation ...

AUKLAND, NZ and DURHAM, N.C. – Companion robots enhanced with artificial intelligence may one day help alleviate the loneliness epidemic, suggests a new report from researchers at Auckland, Duke, and Cornell Universities. Their report, appearing in the July 12 issue of Science Robotics, maps some of the ethical considerations for governments, policy makers, technologists, and clinicians, and urges stakeholders to come together to rapidly develop guidelines for trust, agency, engagement, and real-world efficacy. It also proposes a new way to measure whether a companion robot is helping someone. “Right now, all the evidence ...

Cognitive abilities not only vary among different species but also among individuals within the same species. It is expected that smarter individuals live longer, as they are likely to make better decisions, regarding habitat and food selection, predator avoidance, and infant care. To investigate the factors influencing life expectancy of wild gray mouse lemurs, researchers from the German Primate Center conducted a long-term study in Madagascar. They administered four different cognitive tests and two personality tests to 198 animals, while also measuring their weight and tracking their survival over several years. ...
