Drops of seawater contain traces of an ancient world: New research links chemical changes in seawater to volcanic activity, climate

Sea salt hides a secret: tiny droplets of the seawater from which it came, preserving geologic history. Using specializing equipment obtained from National Science Foundation grant funds, Mebrahtu Weldeghebriel, PhD ’22, a postdoctoral fellow at Princeton University, and Binghamton University Distinguished Professor of Earth Sciences Tim Lowenstein were able to…

After 15 years, pulsar timing yields evidence of cosmic background gravitational waves: Groups report evidence that the cosmos is filled with a background of gravitational waves likely due to mergers of supermassive black hole binaries

The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several groups of researchers from around the world who simultaneously published a slew of journal articles in June describing more than…

Having a bad hair day? Blame your genes!

The first gene mapping study on human scalp hair whorls not only shows that hair whorl direction has a genetic basis, but also that it is affected by multiple genes. Four associated genetic variants that are likely to influence hair whorl direction are identified, as reported in the Journal of…

Physicists demonstrate how sound can be transmitted through vacuum

A classic movie was once promoted with the punchline: “In space, no one can hear you scream.” Physicists Zhuoran Geng and Ilari Maasilta from the Nanoscience Center at the University of Jyväskylä, Finland, have demonstrated, on the contrary, that in certain situations sound can be transmitted strongly across a vacuum…

Over one million acres of tribal land submerged by dams in the US, research finds

Dam constructions have flooded over 1.13 million acres of tribal land in the US contributing to the historic and ongoing struggle against land dispossession for Indigenous peoples in the United States. New research, published in Environmental Research Letters, has identified that a region of tribal land larger than the state…

Tubular tissue advance could pave way for lab-grown blood vessels

Innovative technology that creates ultra-thin layers of human cells in tube-like structures could spur development of lifelike blood vessels and intestines in the lab. The technique, known as RIFLE — rotational internal flow layer engineering — enables the construction of separate layers as delicate as one cell thick. Such versatility…

Childhood cancer: ‘New’ immune system responds better to therapy

Scientists at St. Anna Children’s Cancer Research Institute and the Eberhard Karls University of Tübingen have shown that immunotherapy after stem cell transplantation effectively combats certain nerve tumors in children. Crucially, stem cells from a parent provide children with a new immune system that responds much better to immunotherapies. These…

New approach for treatment-resistant breast cancers

A collaborative study between LSU Health New Orleans School of Medicine, the University of Rochester and Cellestia Biotech AG, a biopharmaceutical company headquartered in Basel, Switzerland, provides compelling evidence that combining an investigational oral drug with standard-of-care medications reverts hormone resistance and increases Rx effectiveness in experimental models of estrogen-receptor…

Sugars in breastmilk could help treat infections, prevent preterm births

Breastfeeding has long been used as a method to help keep newborns healthy and protected against a variety of diseases. But certain sugars naturally found in breastmilk could also help prevent infections before a baby arrives. Researchers reporting in ACS Central Science have found that these sugars can stop a…

AuNi alloy on Au electrodes for hydrogen evolution reaction: Towards a cleaner tomorrow: Researchers show the hydrogen evolution reaction activity of AuNi/Au electrocatalyst increases due to surface defects formed via Ni dealloying

In recent years, hydrogen gas has gained momentum as the fuel for a clean and green future. This carbon-neutral fuel source releases huge amounts of energy via combustion in the presence of oxygen with water vapor as the by-product. One of the most popular methods of hydrogen production is the…

A new ally in fighting brain diseases: Our very own skull

Alzheimer’s, stroke, multiple sclerosis and other neurological diseases cause severe damage due to neuroinflammation mediated by immune cells. Managing this inflammation poses a significant medical challenge because the brain is protected by the skull and additional surrounding membranes that make the brain less accessible for treatment approaches. Scientists had previously…

Brain cells of males and females respond differently to chronic stress

Scientific excellence requires diversity — research conducted by men and women, by people from different backgrounds and with varied worldviews. The need for diversity extends to scientific experiments themselves, but even today the vast majority of studies in the life sciences are done on male mice only, which could harm…

Treatments for poxviruses — including those causing mpox and smallpox — may already exist in licensed drugs: Scientists have discovered how poxviruses evade natural defences in living cells, and realized that drugs to stop them doing this are already available.

Scientists studying how poxviruses evade natural defences in human cells have identified a new approach to treatment that may be more durable than current treatments. This follows their discovery of how poxviruses exploit a cellular protein to evade the host cell defences, and thereby replicate and spread effectively. Existing drugs…

Land-sea relationship is major driver of coral reef health outcomes

Climate change has long been considered as one of the greatest drivers of declining coral reefs, but the specifics of human impact have been largely unverified. In a new paper published in Nature, researchers tracked coral reef health in Hawai’i for 20 years — measuring increasing water acidification, land-based pollution,…

Exercise apps a good prescription to boost healthcare workers’ mental health

Simple home workouts using exercise apps can effectively reduce depressive symptoms in healthcare workers and could be a major tool to combat the global mental health crisis in the sector, says new University of British Columbia research. The study, published today in JAMA Psychiatry, divided participants into either a waitlisted…

Telecommunications cable used to track sea ice extent in the Arctic

A telecommunications fiber optic cable deployed offshore of Oliktok Point, Alaska recorded ambient seismic noise that can be used to finely track the formation and retreat of sea ice in the area, researchers report in The Seismic Record. Andres Felipe Peña Castro of the University of New Mexico and colleagues…

An early warning system for joint heat and ozone extremes in China: Research identifies patterns to predict co-occurrence of heat and ozone extremes in China months

High temperatures exacerbate ground-level ozone production, resulting in a deadly combination of extreme heat and poor air quality that is especially dangerous for children, seniors, and people suffering from preexisting respiratory illnesses. Like most of the globe, China is dealing with increasing temperatures and longer and more frequent heat waves.…

41 dead in new Mediterranean migrant shipwreck tragedy | CNN

Rome CNN  —  Forty-one people reportedly died in a migrant shipwreck near the Italian island of Lampedusa, survivors say, the latest tragedy amid a spike in efforts in people making the dangerous sea crossing from North Africa to Europe. The survivors told the Red Cross that the migrant boat left…

Explosion at plant near Moscow injures at least 25 | CNN

CNN  —  At least 25 people were injured in an explosion at an industrial plant northeast of Moscow, Russian state news agency RIA Novosti reported Wednesday. The blast took place in the area of the boiler room at Zagorsk Optical and Mechanical Plant, in the town of Sergiev Posad, state…

Disclosing ‘true normal price’ recommended to protect consumers from deceptive pricing

Fifty years ago, the Federal Trade Commission (FTC) stopped enforcing deceptive pricing regulations, assuming that competition would keep retailers honest. Since then, competition has increased significantly — yet the practice of posting false, inflated comparison prices alongside sale prices has continued unchecked. Think of an advertisement from a furniture store…
