Polyolefins are resistant to breaking down, making them hard to recycle. Scientists have now discovered a yeast, Yarrowia lipolytica, that uses hydrocarbons derived from polyolefin plastic wastes to produce substances that can be used to make biodegradable polyesters and polyurethanes.

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.
The studies that are frequently touted as proof of concept for a shortened work week are riddled with statistical flaws, according to Olin Business School's Liberty Vittert, who testified March 13 before the U.S. Senate Committee on Heath, Education, Labor and Pensions.

As the nation celebrates Women’s History Month during March, some women leaders at Argonne share their passions and pitfalls as well as mentors and advice that changed their career trajectories.
Technology to stop or prevent colon cancer keeps improving. Still, incident rates remain more stubborn in rural areas than urban centers. The dean of Penn State College of Medicine talks about the barriers.
The giant planet Jupiter, in all its banded glory, is revisited by Hubble in images taken Jan. 5-6, 2024, capturing both sides of the planet. The many large storms and small white clouds are a hallmark of activity in Jupiter's atmosphere.
Bariatric surgery may result in significant cardiometabolic improvements, particularly among younger, female, or white people and those without comorbidities, according to new research published in the Journal of the Endocrine Society.
“While our research does not prove that veterans who experienced these injuries will develop Alzheimer’s disease, it raises the possibility that they may be on a pathway leading to dementia,” said Dr. Ge Li, the paper's first author and an associate professor of psychiatry and behavioral sciences at UW Medicine.
Space travel and zero gravity can take a toll on the body. A new study has found that astronauts with no prior history of headaches may experience migraine and tension-type headaches during long-haul space flight, which includes more than 10 days in space. The study was published in the March 13, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Researchers at the U.S. Department of Energy’s Argonne National Laboratory have created a new material that uses “redox gating” to control the movement of electrons in and out of a semiconducting material.
Published in Nature Communications, Increased Asian Aerosols Drive a Slowdown of Atlantic Meridional Overturning Circulation, identifies the role aerosols over Asia is having on the AMOC, a complex system of currents in the Atlantic Ocean.
Repeats of DNA sequences, often referred to as “junk DNA” or “dark matter,” that are found in chromosomes and could contribute to cancer or other diseases have been challenging to identify and characterize. Now, investigators at the Johns Hopkins Kimmel Cancer Center have developed a novel approach that uses machine learning to identify these elements in cancerous tissue, as well as in cell-free DNA (cfDNA) — fragments that are shed from tumors and float in the bloodstream. This new method could provide a noninvasive means of detecting cancers or monitoring response to therapy. Machine learning is a type of artificial intelligence that uses data and computer algorithms to perform complex tasks and accelerate research.
A new Webb study of two protostars, so young that they have not yet formed planets, has found a variety of molecules ranging from relatively simple ones like methane to complex compounds like acetic acid (familiar to cooks as an ingredient in vinegar). These molecules constitute key ingredients for worlds that might one day host life.
Participation in recreational activities — including golfing, gardening or yard work, woodworking and hunting — may be associated with an increase in a person’s risk for developing ALS.
Middle-age veterans who experienced concussions due to blasts from explosive devices may have biomarkers in their spinal fluid similar to people who develop Alzheimer’s disease, according to a new study published in the March 13, 2024, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A team of researchers at ORNL demonstrated that a light-duty passenger electric vehicle can be wirelessly charged at 100-kW with 96% efficiency using polyphase electromagnetic coupling coils with rotating magnetic fields.
Glucagon-like peptide-1 (GLP-1) agonists such as Ozempic® or Wegovy® (semaglutide), Saxenda® (liraglutide), or Zepbound™ (tirzepatide), have become increasingly popular in promoting weight loss.
For telescopes operating in the vacuum of space, or optical equipment in extreme environments, existing coatings are often insufficient. In the Journal of Vacuum Science & Technology Aresearchers in China turned to atomic layer deposition and developed an ultrablack thin-film coating for aerospace-grade magnesium alloys. The team used alternating layers of aluminum-doped titanium carbide and silicon nitride and together the materials prevent nearly all light from reflecting off the coated surface. The coating absorbs 99.3% of light while being durable enough to survive in harsh conditions.
Declining atmospheric sulfur dioxide levels might be related to the global rise in Legionnaires’ disease, according to a new UAlbany study which examined trends in atmospheric sulfur dioxide, Legionnaires’ disease incidence, and the role of cooling towers in harboring Legionella.
Age-related changes that cause the skin to stiffen and become less elastic may also contribute to higher rates of metastatic skin cancer in older people, according to research by investigators from the Johns Hopkins Kimmel Cancer Center.
The best measurements from Hubble show the universe is now expanding faster than predicted based on observations of how it looked shortly after the big bang. Some scientists suggested that Hubble observations are wrong due to some creeping inaccuracy in its deep-space yardstick. However, Webb’s sharp infrared views of milepost markers known as Cepheids agree with Hubble data.
Taking “study drugs” like Adderall without a diagnosis is not only dangerous in itself, but can lead to other drug use and a decline in mental health, according to new research from Binghamton University, State University of New York.
In the astronomy field, the term “nearby” is quite relative. Neighboring galaxies to our home galaxy, the Milky Way, are a few million light-years away. In contrast, some of the most distant galaxies ever detected, closer to the Big Bang, are billions of light-years away.
Medicaid coverage has historically ended at 60 days postpartum, but according to new data, a significant number of maternal deaths are happening between 43 and 365 days postpartum.
It has been well established that people who live in rural areas in the U.S. are more likely to have diabetes and experience barriers to managing their condition compared to those who live in the suburbs and cities.

These advances are made possible through seamless collaboration between MD Anderson’s world-leading clinicians and scientists, bringing discoveries from the lab to the clinic and back.
Combining the anticancer drugs enfortumab vedotin and pembrolizumab (EV+P) led to significantly improved survival rates among patients with advanced urothelial cancer (the most common type of bladder cancer) compared with standard chemotherapy, according to results of a large international clinical trial involving 185 sites, including the Johns Hopkins Kimmel Cancer Center’s Greenberg Bladder Cancer Institute, in 25 countries.
In a new study from the University of Georgia, researchers found that the time high schoolers spend on so-called enrichment activities—including tutoring, sports, school clubs and even homework—is negatively affecting their mental health. The study also found that any additional enrichment activities are unlikely to benefit students academically. While the ideal number of study hours will vary student by student, researchers found that adding more enrichment activities is unlikely to benefit students. Many people think additional study time or tutoring will lead to better test scores and grades, but this research shows that students are already at their limit. Any more “enrichment” will have negative returns.
