A research team at the University of Göttingen has developed a new method to produce X-ray images in colour. In the past, the only way to determine the chemical composition of a sample and the position of its components using X-ray fluorescence analysis was to focus the X-rays and scan…

A soldier suffers a serious gunshot wound on a remote battlefield or a machinist has a work accident and gets stuck in traffic on the way to the hospital. Secondary, uncontrolled bleeding from traumatic injury is the leading cause of death of Americans from ages one to 46. Amir Sheikhi,…

A new Cedars-Sinai study suggests that some patients diagnosed with behavioral-variant frontotemporal dementia (bvFTD) — an incurable condition that robs patients of the ability to control their behavior and cope with daily living — may instead have a cerebrospinal fluid leak, which is often treatable. Researchers say these findings, published…

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them. The results are published today in eLife. Details of this lifestyle switch could provide new insights into the regulation of algal bloom…

Washington CNN  —  The Biden administration is finalizing plans to send US-made Abrams tanks to Ukraine and could make an announcement as soon as this week, according to three US officials familiar with the deliberations. The timing around the actual delivery of the tanks is still unclear and it normally…

Washington CNN  —  A lawyer for former Vice President Mike Pence discovered about a dozen documents marked as classified at Pence’s Indiana home last week, and he has turned those classified records over to the FBI, multiple sources familiar with the matter told CNN. The FBI and the Justice Department’s…

New York CNN  —  In the past, Oreo has partnered with Lady Gaga, Pokémon and Ritz on new limited-time flavors. Now, it’s working with … itself. And Martha Stewart. The cookie brand’s latest limited-edition cookie is an Oreo stuffed with Oreos. Dubbed “the Most OREO OREO,” the cookie is made…

About 13,200 men and another 2,300 women in the United States over age 50 are estimated to have VEXAS syndrome, according to a new study. Long considered a mystery illness until its genetic basis was identified in 2020, the latest findings, led by researchers at NYU Grossman School of Medicine,…

 The further out in time, the more unreliable a weather forecast. That’s because small variations in initial weather conditions can completely change the entire system, making it unpredictable. Put another way, in the “butterfly effect,” an insect can flap its wings and create a microscopic change in initial conditions that…

Rapid economic growth has pushed rare species of big carnivores to the brink of extinction, but ecologists have suggested our appetite to once again live alongside big cats is increasing. Scientists at the University of Reading studied the relative fortunes of 50 species of large carnivores worldwide over the past…

Cells zealously protect the integrity of their genomes, because damage can lead to cancer or cell death. The genome — a cell’s complete set of DNA — is most vulnerable while it is being duplicated before a cell divides. Cancer cells constantly are dividing, so their genomes are constantly in…

There is scientific evidence that maternal exposure to natural environments supports healthy fetal growth. However, study results up to date had been heterogeneous across regions and there is very little research on the effects of blue spaces such as rivers, the sea or lakes. A new study involving a team…

A new study by researchers at the University of British Columbia and the University of Victoria has shown that common levels of traffic pollution can impair human brain function in only a matter of hours. The peer-reviewed findings, published in the journal Environmental Health, show that just two hours of…

The diagnosis of Parkinson’s disease has shaken many lives. More than 10 million people worldwide are living with it. There is no cure, but if symptoms are noticed early, the disease can be controlled. As Parkinson’s disease progresses, along with other symptoms speech changes. Lithuanian researcher from Kaunas University of…

Every year, the United States spends nearly a trillion dollars fighting metallic corrosion, an electrochemical reaction that occurs when metals oxidize and begin to rust. By taking on this surprisingly insidious issue, researchers have now estimated how much corrosion is gradually worsening global carbon emissions. Global steel production has been…

A camera-trap study of two ecosystems — one with pumas and one without — adds to scientists’ understanding of the many ways apex predators influence the abundance, diversity and habits of other animals, including smaller carnivores. Reported in the journal Ecosphere, the study followed multiple members of the order Carnivora,…

CNN  —  Shailene Woodley says she had a tough time filming last year because of what she was going through personally. In a recently published interview with “Porter,” the actress talked about her experience working on “Three Women,” the Showtime adaptation of Lisa Taddeo’s New York Times bestselling study of…

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan. 5 in Molecular Cell, solves a mystery that has long puzzled biologists. The cells of humans and all other…

It’s clear that chronic stress can impact our behavior, leading to problems like depression, reduced interest in things that previously brought us pleasure, even PTSD. Now scientists have evidence that a group of neurons in a bow-shaped portion of the brain become hyperactive after chronic exposure to stress. When these…

Scientists from The Australian National University (ANU) are drawing inspiration from plants to develop new techniques to separate and extract valuable minerals, metals and nutrients from resource-rich wastewater. The ANU researchers are adapting plant ‘membrane separation mechanisms’ so they can be embedded in new wastewater recycling technologies. This approach offers…

A research group has succeeded in measuring spin transport in a thin film of specific molecules — a material well-known in organic light emitting diodes — at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have…

When two microscopic systems are entangled, their properties are linked to each other irrespective of the physical distance between the two. Manipulating this uniquely quantum phenomenon is what allows for quantum cryptography, communication, and computation. While parallels have been drawn between quantum entanglement and the classical physics of heat, new…

Scientists at the Max Planck Institute of Molecular Plant Physiology in Potsdam (Germany) analyzed for the first time the inheritance of chloroplasts under a wide range of environmental conditions. Contrary to the prevailing view that chloroplasts are only passed on by the mother plant, paternal chloroplasts can also be transmitted…

In the course of optimising key procedures of genome editing, researchers from the department of Developmental Biology / Physiology at the Centre for Organismal Studies of Heidelberg University have succeeded in substantially improving the efficiency of molecular genetic methods such as CRISPR/Cas9 and related systems, and in broadening their areas…

Discovering new drugs has become increasingly rare for independent large pharmaceutical companies in recent times. Almost 60% of new drugs are discovered through mergers and acquisitions and drug licensing. Now, researchers from Ritsumeikan University, Japan, shed light on the recent trends of spinouts from academia and investments in the U.S.A…

It’s a good news, bad news story. Patients whose brain tumors have a mutated enzyme called IDH1 typically live longer than those without the mutation. But even as these tumors are initially less aggressive, they always come back. A key reason: The tumors are resistant to radiation treatment and are…

Kyiv, Ukraine CNN  —  A number of senior Ukrainian officials have resigned or been fired by President Volodymyr Zelensky amid a growing corruption scandal linked to the procurement of war-time supplies, in the biggest shakeup of the government since Russia’s invasion began. During his nightly address on Monday evening, Zelensky…
