Lead pollution in the Aegean Sea region may have begun around 5,200 years ago, according to a paper published in Communications Earth & Environment. The findings suggest that lead pollution due to human activities began approximately 1,200 years earlier than previously thought, and that the expansion of the Roman Empire across the Aegean region led to a significant increase in lead pollution in the region around 2,150 years ago. Andreas Koutsodendris and colleagues analysed the lead content of ...

Studies of sediment cores from the sea floor and the coastal regions surrounding the Aegean Sea show that humans contaminated the environment with lead early on in antiquity. A research team led by geoscientists from Heidelberg University conducted the analyses, which revealed that human activity in the region resulted in lead contamination of the environment approximately 5,200 years ago – much earlier than previously known. Combined with the results of pollen analyses from the sediment cores, this contamination also offers insights into socioeconomic change in the Aegean, even reflecting historical ...

In this global context, Lithuania is undergoing a significant energy transformation as it moves toward a more sustainable and independent future. By aligning its energy ...

An unusually high amount of poliovirus detections in several European countries in recent months has underscored the importance of keeping Europe polio-free, according to an editorial by European Centre for Disease Prevention and Control (ECDC) Director Pamela Rendi Wagner and World Health Organization (WHO) Regional Director for Europe Hans Kluge, which was published on Eurosurveillance. ‘A future without polio remains our goal, but it is by no means a certainty’, warn Rendi-Wagner and Kluge. ‘Every country must remain vigilant to detect the presence of polioviruses through sensitive surveillance systems, prepared to act quickly if any circulation is detected, ...

Tatsuya Yoshida, Mikito Takefuji, and Toyoaki Murohara in the Department of Cardiology, Nagoya University Graduate School of Medicine, identified an enzyme, alpha-kinase 2 (ALPK2) that is specifically expressed in the heart. They found that the enzyme may prevent a stiff heart through activating the gene TPM1 in heart muscle fibers. ALPK2 is a promising new therapeutic target for the treatment of heart failure, especially heart failure with preserved ejection function (HFpEF). The number of heart failure patients is increasing worldwide. ...

WASHINGTON – Being optimistic about the future may help people save more money, and the effect appears strongest among those with lower incomes, according to research published by the American Psychological Association. The study found that people who scored higher on measures of “dispositional optimism” -- the tendency to expect positive outcomes -- saved more money over time compared with their less optimistic peers. The research was published in the Journal of Personality and Social Psychology. "We often think of optimism as rose-colored glasses ...

Women who go on to develop postpartum depression (PPD) may have characteristic levels of neuroactive steroids, molecules derived from the hormone progesterone, in their blood during the third trimester of pregnancy, according to a new study by researchers at Weill Cornell Medicine and the University of Virginia. These molecules influence the brain’s stress response and emotional regulation. The findings, published XX in Neuropsychopharmacology, suggest that this may provide a way to identify women at risk of PPD before ...

Muon spin rotation (µSR) spectroscopy is a powerful technique that helps to study the behavior of materials at the atomic level. It involves using muons—subatomic particles similar to protons but with a lighter mass. When introduced into a material, muons interact with local magnetic fields, providing unique insights into the material’s structure and dynamics, especially for highly reactive species such as radicals. In a new study, a team of researchers led by Associate Professor Shigekazu Ito, from the School of Materials and Chemical Technology, Institute of Science Tokyo, Japan, ...

Kaboom! The first time most of us hear the sound of an explosion is in the movies. Encountering the sound in the real world—even at a distance—has a profoundly different effect. Why? It’s all about context. How we react to sounds and other sensory stimuli depends on how they’re presented. We often don’t know how we’ll respond to something until we experience it. And the sensation is sometimes quite different from what we expected. So, the brain has to adjust quickly. Cold Spring Harbor Laboratory (CSHL) Professor Florin Albeanu explains: “In ...

Hidden within our bones, marrow sustains life by producing billions of blood cells daily, from oxygen-carrying red cells to immune-boosting white cells. This vital function is often disrupted in cancer patients undergoing chemotherapy or radiation, which can damage the marrow and lead to dangerously low white cell counts, leaving patients vulnerable to infection. Now, researchers at the University of Pennsylvania School of Engineering and Applied Science (Penn Engineering), Perelman School of Medicine (PSOM) and the Children’s Hospital of Philadelphia (CHOP) have developed a platform that emulates human marrow’s ...

Research recently published in The Journal of Financial and Quantitative Analysis reveals that politically connected companies were significantly more likely to receive valuable exemptions from the tariffs imposed on U.S. imports from China during the Trump administration. The authors, Veljko Fotak (SUNY Buffalo), Grace Lee (Fordham University), William Megginson (University of Oklahoma), and Jesus Salas, associate professor of finance (Lehigh University), found that companies that made substantial investments in political connections to Republicans prior to and during the beginning of the Trump administration were ...

A solution to injuries from slips and falls may be found underfoot — literally. The footpads of geckos have hydrophilic (water-loving) mechanisms that allow the little animals to easily move over moist, slick surfaces. Researchers in ACS Applied Materials & Interfaces report using silicone rubber enhanced with zirconia nanoparticles to create a gecko-inspired slip-resistant polymer. They say the material, which sticks to ice, could be incorporated into shoe soles to reduce injuries in humans.  Slips ...

Perovskite solar cells (PSCs) present a revolutionary leap in renewable energy technology with their high efficiency, lightweight, and flexible nature.

As dairy farmers dwindle every year, the demand for high-quality milk remains steadfast, driving a surge in dairy farming. Although this shift improves efficiency, it makes managing the health of individual cows more challenging. Effective health management has thereby become a critical issue in the dairy industry. Early detection of abnormalities, swift diagnosis, prevention of disease spread, and maintaining proper breeding cycles are essential for desirable and stable milk production. While there are invasive methods, like using mechanical devices attached to dairy cows for health ...

Researchers from the HUN-REN Biological Research Centre, Szeged (Hungary), have made a concerning discovery about the future of antibiotics. Two recent studies, published just days apart in Nature Microbiology and Science Translational Medicine found that resistance can develop against new antibiotics even before they are widely used, compromising their effectiveness from the start. The studies focused on five critical bacterial species that cause major hospital infections and examined 18 new antibiotics, some already on the market and ...

PULLMAN, Wash. — A new variety of Kentucky bluegrass has been commercially released by researchers at Washington State University. “Matchless,” developed from another bluegrass variety called “Kenblue,” offers seed growers higher yields without the harmful impacts of burning. It also provides consumers with the option of a more environmentally friendly grass. For several decades in the 1900s, Kentucky bluegrass growers burned fields to remove stubble after harvest, reduce thatch buildup, prevent disease, and for a number ...
