Mothers and daughters have a strong bond, yet do you know that connections reminiscent of this close relationship extend all the way to the cellular level? During the process of cell division, new daughter cells inherit a mix of genetic material and other molecules from their mother cells. This inheritance includes both beneficial components, which can help them for a robust start in life, and potentially harmful mutations or damaged molecules, posing significant challenges for the newly born daughter cells. How daughter cells manage and ...

Researchers at the Weizmann Institute of Science in Israel have identified a yeast that could be used to prevent invasive candidiasis, a major cause of death in hospitalized and immunocompromised patients. The study, to be published March 18 in the Journal of Experimental Medicine (JEM), shows that the novel yeast lives harmlessly in the intestines of mice and humans and can displace the yeast responsible for candidiasis, Candida albicans. Millions of microbial species live within or on the human body, many of them being harmless or even beneficial to human health. The microscopic yeast C. albicans is commonly found in the intestines ...

Global coffee consumption generates millions of tons of spent coffee grounds each year, which can be damaging to wildlife and the environment. However, new research published in the Journal of Chemical Technology and Biotechnology reveals that spent coffee grounds could be repurposed to act as a powerful adsorbent of bentazone, a herbicide commonly used in agriculture that is highly neurotoxic. In the study, investigators found that when they used zinc chloride to activate the carbon from spent coffee grounds, the activated carbon showed a 70% efficiency in bentazone removal. ...

Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe’s brightest objects. The new map logs the location of about 1.3 million quasars in space and time, the furthest of which shone bright when the universe was only 1.5 billion years old. (For comparison, the universe is now 13.7 billion years old.) “This quasar catalog is different from all previous catalogs in that it gives us a three-dimensional map of the largest-ever volume of the universe,” says map co-creator David Hogg, a ...

Life can be hard for a raptor. If you’re a teenager from the city, it’s even harder. That’s according to a new study published in the Journal of Raptor Research titled “Causes of Death of Female Cooper’s Hawks (Accipiter cooperii) from an Urban Setting in New Mexico, USA,” conducted by Brian A. Millsap and his colleagues at the US Fish and Wildlife Service. Over the course of 11 years, his research team affixed GPS transmitters to 158 female Cooper’s hawks in the Albuquerque area. Of those, 88 died and were found, allowing the researchers to investigate cause of death. The ...

Middle-aged adults in the U.S. tend to report significantly higher levels of loneliness than their European counterparts, possibly due in part to weaker family ties and greater income inequality, according to research published by the American Psychological Association.  “Loneliness is gaining attention globally as a public health issue because elevated loneliness increases one’s risk for depression, compromised immunity, chronic illness and mortality,” said lead author Frank Infurna, PhD, an associate professor of psychology at Arizona State ...

COLUMBUS, Ohio – Venting about a source of anger might feel good in the moment, but it’s not effective at reducing the rage, new research suggests. Instead, techniques often used to address stress – deep breathing, mindfulness, meditation, yoga or even counting to 10 – have been shown to be more effective at decreasing anger and aggression. Researchers analyzed over 150 studies involving more than 10,000 participants and found that what really works to reduce anger is lowering physiological arousal – in other words, turning down the heat. Activities that increased arousal overall ...

Images When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world.  But University of Michigan scientists are looking at something a little more tangible: coral.  Examining samples from corals in the Great Barrier Reef, the researchers discovered between 1750 and present day, as the global climate warmed, wet-season rainfall in that part of the world increased by about 10%, and the rate of extreme rain events more than doubled. Their results are published in Nature, Communications Earth and Environment. "Climate scientists ...

An “anti-hunger” molecule produced after vigorous exercise is responsible for the moderate weight loss caused by the diabetes medication metformin, according to a new study in mice and humans. The molecule, lac-phe, was discovered by Stanford Medicine researchers in 2022. The finding, made jointly by researchers at Stanford Medicine and at Harvard Medical School, further cements the critical role the molecule, called lac-phe, plays in metabolism, exercise and appetite. It may pave the way to a new class of weight loss drugs. “Until now, the way metformin, which is prescribed to control blood sugar ...

After birth, liver cells acquire different functions depending on their location. CNIO researchers have discovered that this specialization occurs with the onset of oral food intake, which is intermittent. The alternation of periods with and without nutrients activates the mTOR gene and causes liver cells to specialize, which completes liver maturation. The finding is the result of an investigation into the consequences of sedentary lifestyles and overeating in today’s society, where the body ...

Scents, such as coffee, flowers, or freshly-baked pumpkin pie, are created by odor molecules released by various substances and detected by our noses. In essence, we are smelling molecules, the basic unit of a substance that retains its physical and chemical properties. A research team led by Dr. ZHOU Wen from the Institute of Psychology of the Chinese Academy of Sciences has discovered that this process of "smelling" involves an analysis of submolecular structural features. The study was published online in Nature Human Behaviour on March 18. In this study, the ...

Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions – but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers from the University of Basel are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold. More sustainable and cost-effective applications are now tantalizingly close. Industrial chemical reactions ...

A new study led by researchers at McLean Hospital (a member of Mass General Brigham) and Washington State University used advances in digital testing to demonstrate that naturally occurring glucose fluctuations impact cognitive function in people with Type 1 Diabetes (T1D). Results showed that cognition was slower in moments when glucose was atypical – that is, considerably higher or lower than someone’s usual glucose level. However, some people were more susceptible to the cognitive effects of large glucose fluctuations than others. “In trying to understand how diabetes impacts the brain, our research shows that it is important to consider not only how people ...

NEW ORLEANS, March 18, 2024 — Doctors have long prescribed exercise to improve and protect health. In the future, a pill may offer some of the same benefits as exercise. Now, researchers report on new compounds that appear capable of mimicking the physical boost of working out — at least within rodent cells. This discovery could lead to a new way to treat muscle atrophy and other medical conditions in people, including heart failure and neurodegenerative disease. The researchers will present their ...

NEW ORLEANS, March 18, 2024 — Buildings and production of the materials used in their construction emit a lot of carbon dioxide (CO2), a potent greenhouse gas that contributes to global warming and climate change. But storing CO2 in building materials could help make them more environmentally friendly. Scientists report that they have designed a composite decking material that stores more CO2 than is required to manufacture it, providing a “carbon-negative” option that meets building codes and is less expensive than standard composite decking. The researchers will present their results today at the spring meeting of the American Chemical Society ...

NEW ORLEANS, March 18, 2024 – During cold and flu season, excess mucus is a common, unpleasant symptom of illness, but the slippery substance is essential to human health. To better understand its many roles, researchers synthesized the major component of mucus, the sugar-coated proteins called mucins, and discovered that changing the mucins of healthy cells to resemble those of cancer cells made healthy cells act more cancer-like. The researcher will present her results today at the spring meeting of the American Chemical Society (ACS). ACS Spring 2024 is a hybrid meeting being held virtually and in person March 17-21; it features nearly 12,000 ...

Research from the University of Southampton has identified common issues women face when experiencing periods while homeless. A review of research published in Women and Health has found homeless women experienced practical challenges in managing menstruation alongside feelings of embarrassment and shame, with many ‘making do’ due to inadequate provision. The researchers say it’s high time to address the provision of menstrual health resources as a basic human right. Dr Stephanie Barker, a teaching fellow at the University of ...

Your skin becomes red and spots filled with pus appear, so you visit a dermatologist. When these symptoms spread to the skin throughout the body, it is difficult for the physician to distinguish whether it is generalized pustular psoriasis (GPP) or acute generalized exanthematous pustulosis (AGEP), as both have similar symptoms. The two diseases run different courses and require different treatments. Without proper treatment, the symptoms can worsen severely and cause complications, so it is essential to distinguish between them. Researchers ...
