DALLAS, Oct. 30, 2025 — Both on the court and off, cardiovascular disease is the leading killer of women in the United States, taking the lives of more than 440,000 women each year, according to the American Heart Association, a relentless force changing the future of health for everyone everywhere. The Association’s Go Red for Women® movement is working to raise awareness, improve education and inspire action to help women better understand and learn how to prevent their number one health threat. For the first time, 19 National Collegiate Athletic Association (NCAA) women’s ...

The origins of vivid colours within the gemstone ammolite — a rare type of brightly coloured fossilised ammonite shell — are reported in research published in Scientific Reports.  The colours of ammolite occur within a preserved layer of nacre — also known as mother-of-pearl — which consists of layered plates of the mineral aragonite and a small amount of organic material such as proteins. Although it is thought that the colours of ammolite arise from the interaction of light with these layers, the origins of these colours have not been evaluated experimentally.  Hiroaki ...

LAWRENCE — A new study appearing in Nature Microbiology analyzes soils sampled across the state of Kansas to determine the importance of “legacy effects” — or how soils from a specific location are influenced by microbes that have evolved in response to the specific climate at that site for many years. “The bacteria and fungi and other organisms living in the soil can actually end up having important effects on things that matter, like carbon sequestration, nutrient movement and what we’re particularly interested in — ...

What if everything we know about T. rex growth is wrong? A complete tyrannosaur skeleton has just ended one of paleontology’s longest-running debates – whether Nanotyrannus is a distinct species, or just a teenage version of Tyrannosaurus rex.  The fossil, part of the legendary “Dueling Dinosaurs” specimen unearthed in Montana, contains two dinosaurs locked in prehistoric combat: a Triceratops and a small-bodied tyrannosaur. That tyrannosaur is now confirmed to be a fully grown ...

Washington, DC—Our galaxy’s most abundant type of planet could be rich in liquid water due to formative interactions between magma oceans and primitive atmospheres during their early years, according to new research published in Nature by Carnegie’s Francesca Miozzi and Anat Shahar. Of the more than 6,000 known exoplanets in the Milky Way, so-called Sub-Neptunes are the most common. They are smaller than Neptune and more massive than Earth and believed to have rocky interiors with thick hydrogen-dominated ...

Systemic light chain (AL) amyloidosis is a rare and life-threatening disorder characterized by the deposition of misfolded immunoglobulin light chains as insoluble amyloid fibrils in various tissues and organs, leading to progressive structural and functional impairment. Commonly affected sites include the heart, kidneys, liver, gastrointestinal tract, and nervous system, with cardiac involvement being the primary determinant of prognosis. Due to its nonspecific clinical presentation and multisystem nature, AL amyloidosis is often diagnosed at an advanced stage, ...

Lactate, once considered a metabolic waste product, is now recognized as a key regulator of cellular homeostasis and disease progression. In gynecological malignancies—including ovarian, cervical, and endometrial cancers—lactate accumulation drives a novel post-translational modification known as lactylation. This modification serves as a critical bridge between metabolic reprogramming and epigenetic regulation, promoting tumor proliferation, metastasis, and therapy resistance. Emerging therapeutic strategies targeting lactate production, transport, and lactylation itself show significant anticancer potential, particularly when combined with immunotherapy. This ...

Background and objectives Emerging evidence implicates immune dysregulation and neuroinflammation in the pathogenesis of epilepsy, yet the causal mechanisms remain unclear.

Stroke is a leading cause of death and disability, affecting 1 in 4 people during their lifetime. Stroke happens when blood vessels in the brain get clogged or damaged, impairing blood flow and oxygen supply to the brain, which leads to death of neurons and other brain cells. Although brain damage can be limited by interventions to restore blood flow, most stroke survivors experience some lifelong impairments of e.g. speech, movement, or cognitive function.   Despite the existence of immature stem cells in the brain, their role in repair is uncertain and the brain’s ...

If cancer is a disease of overabundance, where cells divide without restraint and tumors grow despite the body’s best interests, then degenerative diseases are disorders of deprivation. When malfunctions occur in the biological machinery our muscles or our brains use for renewal and repairs, these tissues gradually wither. This kind of decline is the hallmark of diseases such as Alzheimer’s disease or Duchenne muscular dystrophy. Scientists have long sought to develop treatments that enhance the muscle’s self-renewal capabilities ...

More than half of American adults misunderstand or underestimate the link between alcohol consumption and cancer  Alcohol drinkers are especially likely to believe that drinking has no effect on cancer risk Correcting these misbeliefs may strengthen adherence to U.S. Surgeon General’s alcohol consumption guidelines to lower cancer risk HOUSTON, OCTOBER 30, 2025 – Despite clear evidence linking alcohol use to increased cancer risks, public awareness of this connection remains low in the U.S., according to new research from The University of Texas MD Anderson ...

WASHINGTON — Researchers have developed a new technology that can shape the spectrum of light emitted from a laser frequency comb across the visible and near-infrared wavelengths with more precision than previously possible. This advance could provide an important new tool in the hunt for Earth-like planets outside our solar system. When searching for exoplanets, astronomers use high-precision spectroscopy to detect tiny shifts in starlight that reveal a star’s subtle “wobble” due to an orbiting planet. But for Earth-sized planets, these wavelength changes are smaller than the spectrograph’s ...

Sharing happy moments with a partner may be good for older people’s health, lowering the level of the stress hormone cortisol in their bodies, according to research published by the American Psychological Association.   “We know from lots of research that positive emotions like happiness, joy, love and excitement are good for our health -- they’ve even been linked to living longer. But most of this research looks at people’s emotions as if they happen in isolation,” said study lead author Tomiko Yoneda, PhD, of the University of California Davis. “In real life, though, our most powerful positive emotions often happen when we’re connecting ...

Conventional approaches to cyborg insect preparation involve cutting antennae or cerci (sensory appendages) to implant electrodes, or using adhesives (like poly ionic liquid gels) to attach noninvasive films. “The methods have flaws: (1) Invasive implantation irreparably damages sensory organs, reducing the insect’s ability to detect obstacles and navigate; (2) Adhesive-based films degrade over time, cause exoskeleton harm during removal, and require skillful application—extending preparation time and limiting reuse; (3)Ethically, cutting appendages violates the “3Rs” framework (Replacement, Reduction, Refinement) for humane animal research, raising concerns about ...
