PULLMAN, Wash. – Taking a cue from the structural complexity of trees and bones, Washington State University engineers have created a way to 3D-print two types of steel in the same circular layer using two welding machines. The resulting bimetallic material proved 33% to 42% stronger than either metal alone, thanks in part to pressure caused between the metals as they cool together. The new method uses commonplace, relatively inexpensive tools, so manufacturers and repair shops could use it in the ...

Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study by the Martin Luther University Halle-Wittenberg (MLU) and the Chinese Academy of Sciences in "Ecology Letters", pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance ...

About The Study: This systematic review and meta-analysis including 52 studies found children, adolescent, and young adult patients with cancer experience an increased risk of depression, anxiety, and psychotic disorders after cancer remission compared with siblings and noncancer-matched controls. Timely identification, preventive efforts, and psycho-oncological intervention for psychological comorbidity are recommended.  Authors: Ainsley Ryan Yan Bin Lee, M.B.B.S. (Hons.), and Cyrus Su Hui Ho, Ph.D., of the National University of Singapore, are the corresponding authors. To access the embargoed study: Visit our For The Media ...

Evidence is mounting that astronauts are more susceptible to infections while in space. For example, astronauts on board the International Space Station (ISS) commonly suffer from skin rashes, as well as respiratory and non-respiratory diseases. Astronauts are also known to shed more live virus particles, for example Epstein-Barr virus, varicella-zoster responsible for shingles, herpes-simplex-1 responsible for sores, and cytomegalovirus. These observations suggest that our immune system might be weakened by space travel. But what could cause such an immune deficit? “Here we show that the expression of many ...

As North America recovers from some of the worst air quality in decades due to wildfires, one of the largest and most comprehensive studies into the long-term health impact of smoke exposure raises significant concerns about the long-term health impact of the Canadian wildfires. The study found that a 10 μg/m3 increase of wildfire-related PM2.5 exposure was associated with a 0.4% higher risk of all-cause and nonaccidental mortality, and a 0.5% increase in risk of dying from neoplasms.  On June 8, at the peak of the wildfire pollution, ...

The lack of registration of medicines in Kenya, Tanzania and Uganda is limiting access to safe, effective, and affordable essential medicines, according to a new analysis from Newcastle University in the UK and Makerere University in Uganda, published by the Journal of the Royal Society of Medicine. Before a medicine can be made available in a country, manufacturers must apply to the medicine regulatory agency of the country for a licence to sell it and demonstrate the medicine is safe and effective. This is known as market registration. The researchers compared the ...

Researchers have shed light on how a highly infectious virus, that has recently transferred from animals to people, is able to enter human cells. The University of Queensland’s Dr Ariel Isaacs and Dr Yu Shang Low have uncovered the structure of the fusion protein of Langya virus, which was discovered in people in eastern China in August 2022. Dr Isaacs said the virus caused fever and severe respiratory symptoms and was from the same class of viruses as the deadly Nipah and Hendra viruses. “We’re ...

A UK-wide consortium is developing technologies to use nanoparticles as state-of-the-art sensors on small, shoebox-sized satellites known as CubeSats. The Universities of Warwick, Swansea and Strathclyde have been awarded £250k to further research into nanoparticles and quantum physics in the application of space technology. Recent advances in the field of levitated optomechanics (the motion of tiny particles held and measured in free space by laser light), have shown that nanoparticles can exhibit behaviours that are governed by the laws of quantum mechanics (a fundamental theory which describes how atoms and subatomic particles interact). This has led to nanoparticles, which are ...

INTRODUCTION Coastal sand dunes provide the first line of defense from storms for some of the most economically valuable and ecologically important landscapes in the world (1–3). A current and broadly accepted paradigm is that vegetation reduces the erosion of these dunes during wave attack (4–7). The existing body of dune research shows that a greater size (8), density (9–11), and diversity (12) of plants are associated with less erosion, although these studies have been limited ...

What started as a simple errand to deposit a check at a bank drive-through became the kind of “aha” moment found mostly in books and movies. Georgia Tech researchers had been working on an idea to simplify traditional direct air capture (DAC) systems. Their approach used ambient wind flow to draw air across a new kind of coated carbon fiber to grab CO2. That would eliminate the loud fans used in many systems. And the carbon fiber strands could be quickly heated to release the captured carbon dioxide with ...

The industrial sector – made up of businesses that support processing raw materials for manufacturing and consumer goods – is a major contributor to greenhouse gas emissions and one that has proven difficult to decarbonize. In China, much of the industrial sector is organized into ‘parks’ that have been zoned as areas for concentrated industrial activities. China has more than 2,500 industrial parks that are currently largely powered by coal. A recent study led by researchers at Princeton University finds that this clustering of industry provides unique and overlooked opportunities for targeted energy supply emissions reduction ...

Antarctic ice shelves have experienced only minor changes in surface melt rates over the past four decades, unlike the rapid increase in surface melt experienced by Greenland’s glaciers during the same time period, according to new research. The news is not cause for celebration just yet, though—the researchers expect Antarctic ice shelf surface melt rates to increase substantially in the coming decades due to rising global air temperatures. Ice shelves are the parts of glaciers that extend into the ocean and float on top of seawater. In a new study published today in Geophysical Research Letters, glaciologists ...

 The National Academy of Medicine (NAM) is partnering with a group of leading health, bioethics, equity, tech, patient advocacy, and research organizations, including The Hastings Center, to develop an Artificial Intelligence Code of Conduct (AICC). Dr. Vardit Ravitsky, incoming president of The Hastings Center, who will serve on the steering committee, said, “we must urgently develop guidance for the ethical use of AI – perhaps the most transformative technology of our generation.”  ...
