In the journal Angewandte Chemie, a research team has now introduced a completely new approach for treating herpes. Their method is based on the inhibition of an enzyme that is needed for…
Many people with diseases such as cancer or diabetes or those who have had a heart attack or stroke also suffer from depression. How effective are antidepressants for these patients? And are they just as safe for these people as for those without physical health problems? Researchers from Charité —…
Neutrinos are ubiquitous elementary particles that interact only very weakly with normal matter. Therefore, they usually penetrate it unhindered and are therefore also called ghost particles. Nevertheless, neutrinos play a predominant role in the early universe. In order to fully explain how our universe evolved, we need above all to…
Antarctica’s vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts from European research institutes has now provided the first systematic stability inspection of the ice sheet’s current state. Their diagnosis: While they found no indication of…

Social media videos geolocated by CNN showed the attack in the vicinity of the military base. In a Telegram…
CNN — From the moment Russia’s full-scale invasion of Ukraine seemed inevitable, Europe knew it would soon have to ask itself some very complicated questions. High among those was whether the continent could wean itself off the Russian gas it had thirstily guzzled for decades – and avoid being at the mercy of President Vladimir Putin should he…
US Secretary of State Antony Blinken visited Kyiv on Wednesday for his third trip to the Ukrainian capital since the start of Russia’s full-scale invasion, where he doubled down on US support for Kyiv’s counteroffensive, announcing more than a billion dollars of additional US aid and underscoring for an audience back…
Treating newly diagnosed Type 1 diabetes patients with semaglutide (trade names Ozempic, Wegovy and Rybelsus) may drastically reduce or even eliminate their need for injected insulin. Those are the remarkable findings of a small University at Buffalo study reported in the New England Journal of Medicine and published online on…
Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify the concept as the amount of disorder in the universe, neglecting its underlying quantitative nature. In The Physics Teacher, co-published by AIP Publishing and…
Van Andel Institute scientists and collaborators have identified a key part of a mechanism that annotates genetic information before it is passed from fathers to their offspring. The findings, published today in the journal Science Advances, shed new light on genomic imprinting, a fundamental, biological process in which a gene…
A study of twins shows that having a concussion early in life is tied to having lower scores on tests of thinking and memory skills decades later as well as having more rapid decline in those scores than twins who did not have a concussion, or traumatic brain injury (TBI).…
The shape and size of a grain of rice, the new device can conduct dozens of experiments at once to study the effects of new treatments on some of the hardest-to-treat brain cancers. Researchers from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, have…
As the Earth’s human population grows, greenhouse gas emissions from the world’s food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth, but eliminate it altogether by generating net negative emissions — reducing more greenhouse gas than…
Remembering the order of information is central for a person when participating in conversations, planning everyday life, or undergoing an education. A new study, published in the scientific journal PLoS One, shows that this ability is probably human unique. Even the closest relatives of humans, such as bonobos, do not…
Not only does a lack of sleep make you feel awful, research has shown it impairs the brain. What’s more, sleep loss over long periods can even increase risk for Alzheimer’s and other neurological diseases. Researchers want to understand how sleep deprivation causes this harm. In a new study in…
A good night’s sleep has many proven health benefits, and a new Scripps Research study suggests one more: preventing opioid relapse.
