Young adults with elevated cholesterol often go untreated, study finds

NEW ORLEANS (Nov. 6, 2025) —Fewer than half of young adults with severely high low-density lipoprotein (LDL-C), or “bad” cholesterol, levels start taking a statin within five years of first high LDL-C measurement, according to a study published in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s 2025 Scientific Sessions. The 2018 ACC/AHA Cholesterol Guideline recommends a statin in patients with LDL-C over 190 mg/dL and these ...

More women sought permanent contraception after Supreme Court Dobbs decision

HERSHEY, Pa. — In June 2022, the U.S. Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization ended the federal constitutional right to abortion and returned authority to individual states to regulate abortion. A new study from researchers at Penn State, Albany Medical Center, University of South Florida and University of Tennessee Medical Center revealed that the change in abortion policies appears to have a trickle-down effect, influencing reproductive health and family planning decisions. The research team found that the number of women undergoing tubal ligations — ...

Growing transgenic plants in weeks instead of months by hijacking a plant’s natural regeneration abilities

Plant biologists have developed a method for growing transgenic and gene-edited plants that cuts the slow and expensive process down from months to weeks. Publishing November 6 in the Cell Press journal Molecular Plant, the method takes advantage of plants’ natural ability to regenerate after being wounded or pruned. By injecting bacteria carrying genetic instructions for wound healing and regeneration into a pruned plant’s wound site, the researchers triggered the plant to grow new shoots, some of which were transgenic and gene edited. The method shows potential even in species that ...

Informal human milk sharing among US mothers

About The Study: In this large, diverse sample of first-time mothers in the U.S., 1 in 27 participants reported feeding their infants shared human milk. Prior work indicates that families engage in many, but not all, recommended milk sharing risk mitigation measures and fear disclosing their milk sharing to practitioners. Given the prevalence in this study, pediatric practitioners should be aware that milk sharing occurs across demographics; they can counsel families considering or using shared milk on risks and risk-reduction strategies ...

Non-prescription pain meds work equally well for men and women after tooth extraction

Over-the-counter pain medications work as well or better than opioids after wisdom tooth extraction for both men and women, according to a Rutgers Health-led follow-up to a landmark paper on comparative pain relief. That first paper on the collective experience of more than 1,800 trial patients found that the combination of ibuprofen and acetaminophen provided better pain relief than hydrocodone with acetaminophen for the first two days after surgery and greater satisfaction over the post-operative period. The new subgroup analysis, published in JAMA Network Open, demonstrated that the results held for both ...

UBC study shows good B.C. abortion pill access, but gaps remain

Most pharmacies in British Columbia can provide the abortion pill mifepristone within days, but uneven access still leaves some women facing barriers to this time-sensitive medication, according to new research. The study, published Nov. 6 in JAMA Network Open, offers the first province-wide look at pharmacy-level access to mifepristone in B.C. Mifepristone is used for medical abortions and can be prescribed across Canada by any physician or nurse practitioner and filled at community pharmacies. Initially available only from pharmacists who had completed a training module and pharmacies registered with the manufacturer, Health Canada removed these requirements ...

Meditation retreat rapidly reprograms body and mind

Researchers at the University of California San Diego have found that an intensive retreat combining multiple mind-body techniques, including meditation and healing practices, produced rapid and wide-ranging changes in brain function and blood biology. The researchers found that the retreat engaged natural physiological pathways promoting neuroplasticity, metabolism, immunity and pain relief. The findings, published in Communications Biology, provide insights into how consciousness and psychological practices can enhance physical health. Meditation and other mind-body practices ...

Populist parties choose divisive issues on purpose, researchers say

Election researchers from across Europe have looked at how populist parties profile themselves on Facebook. Their findings are quite clear. "Populist parties much more often use controversial, divisive issues when they want to show themselves to potential voters," says Melanie Magin, a professor of media sociology at the Norwegian University of Science and Technology (NTNU's) Department of Sociology and Political Science. Magin and her fellow researchers believe this is probably quite deliberate in order to get the debate into a track that these parties believe they benefit from. The elections to the European Parliament ...

Hollings researcher co-leads AACR subcommittee calling for nicotine limits

The American Association for Cancer Research (AACR) has endorsed a federal policy that would make cigarettes far less addictive. The proposed policy by the Food and Drug Administration (FDA) sets a maximum nicotine product standard, limiting nicotine levels in combustible cigarettes and related tobacco products to 0.7 milligrams per gram (mg/g) – about 95% less than what is currently allowed. That reduction would make cigarettes minimally or nonaddictive, striking at the chemical that keeps people hooked. The AACR policy statement is published in Clinical Cancer Research. Leading the policy statement ...

World’s first discovery of ice XXI: A new form of ice born under two gigapascals of pressure at room temperature

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has successfully observed, for the first time, the multiple freezing-melting process of water under ultrahigh pressure exceeding 2 gigapascals (2 GPa) at room temperature on a microsecond (μs, one-millionth of a second) timescale. This breakthrough led to the world’s first discovery of a previously unknown crystallization pathway of water and a new 21st ice phase, named Ice XXI. While ice generally forms when water cools below 0 °C, it can ...

Study finds link between eczema patterns and children’s ability to outgrow food allergies

ORLANDO (Nov. 6, 2025) – New research presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting suggests that the timing of when eczema begins, as well as how long it lasts and how severe it is, may influence a child’s ability outgrow food allergies. “Food allergy and eczema often appear together in childhood, but scientists don’t fully understand how one condition affects the other,” says Nicole Koulov, 2nd year medical student at University of Texas and ACAAI member who has worked with the FORWARD team under supervision of Mahboobeh Mahdavinia, MD, PhD on this project. “We examined surveys from children with a ...

Double disadvantage hurts more than twice as much

Belonging to more than one marginalized group can make building and maintaining social connections significantly harder, often in ways that go far beyond a simple sum of disadvantages. A new study shows how inequalities in social ties don’t just add up – they can amplify one another. Why do some people have more friendships, more support, and more opportunities – while others seem to have far fewer? Is it simply a matter of personal choices, or do structural patterns play a deeper role? For individuals who belong to a disadvantaged social group, forming connections tends to be more ...
