Live updates: Russia’s war in Ukraine, attacks on Pskov airport and Kyiv

Russia conducted a “massive” attack on Ukraine’s capital Kyiv on Tuesday night using drones and missiles, said Serhii Popko, head of the Kyiv city military administration, on Wednesday. “Kyiv has not experienced such a powerful attack since spring,” Popko wrote on Telegram.  Popko said several groups of drones traveled towards Kyiv “from…

Neptune’s disappearing clouds linked to the solar cycle

Astronomers have uncovered a link between Neptune’s shifting cloud abundance and the 11-year solar cycle, in which the waxing and waning of the Sun’s entangled magnetic fields drives solar activity. This discovery is based on three decades of Neptune observations captured by NASA’s Hubble Space Telescope and the W. M.…

Yeast studies show that diet in early life matters for lifelong health

Researchers at the Babraham Institute are proposing an alternative link between diet and ageing based on studies in yeast. Dr Jon Houseley and his team have published their experiments, showing that healthy ageing is achievable through dietary change without restriction by potentially optimising diet, and that ill-health is not an…

A lightweight wearable device helps users navigate with a tap on the wrist

Scientists at Rice University in Houston, Texas have developed a fabric-based wearable device that “taps” a user’s wrist with pressurized air, silently helping them navigate to their destination. The study, published August 29 in the journal Device, demonstrated that users correctly interpreted which direction the device was telling them to…

Some hosts have an ‘evolutionary addiction’ to their microbiome

We’ve long known that hosts malfunction without their microbiome — whether they are missing key microbial species or are completely microbe free. This malfunctioning is usually explained by the need for microbes to perform unique and beneficial functions, but evolutionary ecologist Tobin Hammer of the University of California, Irvine, is…

Neural network helps design brand new proteins

With their intricate arrangements and dynamic functionalities, proteins perform a plethora of biological tasks by employing unique arrangements of simple building blocks where geometry is key. Translating this nearly limitless library of arrangements into their respective functions could let researchers design custom proteins for specific uses. In Journal of Applied…

AI-powered triage platform could aid future viral outbreak response

A team of researchers from Yale University and other institutions globally has developed an innovative patient triage platform powered by artificial intelligence (AI) that the researchers say is capable of predicting patient disease severity and length of hospitalization during a viral outbreak. The platform, which leverages machine learning and metabolomics…

Brighter comb lasers on a chip mean new applications

Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications. The advance could lead to chip-based instruments that can make precision measurements that were previously possible only in a…

Sensors harnessing light give hope in rehabilitation

Recently, a Korean company donated a wearable robot, designed to aid patients with limited mobility during their rehabilitation, to a hospital. These patients wear this robot to receive assistance for muscle and joint exercises while performing actions such as walking or sitting. Wearable devices including smartwatches or eyewear that people…

Reduced risk of bleeding with modern blood thinners

Modern blood-thinning drugs (known as NOACs) reduce the risk of serious bleeding by up to 45 percent compared to the traditional drug Waran in the treatment of blood clots in the legs and lungs, according to a comprehensive and long-term study conducted at the University of Gothenburg. Blood thinners are…

Maintaining stable weight increases longevity among older women

Reaching the age of 90, 95 or 100, known as exceptional longevity, was more likely for women who maintained their body weight after age 60, according to a multi-institutional study led by University of California San Diego. Older women who sustained a stable weight were 1.2 to 2 times more…

Thin-film batteries rechargable in just one minute

The Empa spin-off BTRY wants to revolutionize rechargeable batteries: Their thin-film batteries are not only safer and longer-lasting than conventional lithium-ion batteries, they are also much more environmentally friendly to manufacture and can be charged and discharged in just one minute. For now, the battery is very small, but the…

Graphene: Perfection is futile

It has long been known that graphene has excellent electronic properties. However, it was unclear until now how stable these properties are. Are they destroyed by disturbances and additional effects, which are unavoidable in practice, or do they remain intact? Scientists have now succeeded in developing a comprehensive computer model…

Prescription for fruits, vegetables linked to better heart health, food security

People at increased risk for cardiovascular disease who participated in produce prescription programs increased their consumption of fruits and vegetables, which was associated with improved body mass index (BMI), blood sugar and blood pressure levels, as well as a decrease in food insecurity. This new research was published today in…

Wildfire, soil emissions increasing air pollution in remote forests

Satellite data from across California’s landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from University of California, Davis, published today in the journal Environmental Research Letters. Nitrogen dioxide is short-lived in the…

Can an artificial kidney finally free patients from dialysis?

Scientists at UC San Francisco are working on a new approach to treating kidney failure that could one day free people from needing dialysis or having to take harsh drugs to suppress their immune system after a transplant. They have shown for the first time that kidney cells, housed in…

Common origin behind major childhood allergies

Several major childhood allergies may all stem from the community of bacteria living in our gut, according to a new study led by researchers at the University of British Columbia and BC Children’s Hospital. The research, published in Nature Communications, identifies gut microbiome features and early life influences that are…

Your genes influence whether depression leads to other diseases

Almost one in five Danes experiences depression during their lives. A new study from Aarhus University now shows that the genetic risk of depression can be linked to an increased genetic risk of other psychiatric diagnoses. The study has just been published in Nature Medicine. Through a detailed genetic scan,…

Care robots: Ethical perceptions and acceptance

Countries like Japan are experiencing declining birth rates and an aging population. The increased burden of care for this aging population may lead to a shortage of caregivers in a decade’s time. Thus, the recruitment and allocation of resources must be planned in advance. Technological interventions in the form of…

Quantum discovery offers glimpse into other-worldly realm

The field of quantum physics is rife with paths leading to tantalising new areas of study, but one rabbit hole offers a unique vantage point into a world where particles behave differently — through the proverbial looking glass. Dubbed the ‘Alice ring’ after Lewis Carroll’s world-renowned stories on Alice’s Adventures…
