Study after study shows that walking is very good for those who are able, and generally more is better. A 2023 study found that even 4,000 steps a day improves all-cause mortality risk. (The U.S average is 4,000 to 5,000.) For each 1,000 extra daily steps, risk decreased by 15%. Walk Scores have been used since 2007 to quantify how quickly people can typically walk to amenities like grocery stores and schools in an area. Cities are assigned scores from 0 to 100; for instance, Seattle’s 74 means it’s “very walkable.” It may seem self-evident that in cities ...

Cancer is the leading cause of disease-related death in childhood. This is in part due to cancer-associated genes called oncogenes that can be found far from chromosomes in cell nuclei on ring-shaped DNA inside tumor cells. Circular extra-chromosomal DNA elements (ecDNA) are pieces of DNA that have broken off normal chromosomes and then been wrongly stitched together by DNA repair mechanisms. This phenomenon leads to circular DNA elements floating around in a cancer cell. “We have shown that these ecDNAs are ...

If you’ve been to a routine eye exam at the optometrist’s office, chances are you’ve had to place your chin and forehead up close to a bioimaging device.  It’s known as optical coherence tomography (OCT), and it’s widely used in eye clinics around the world. OCT uses light waves to take high-resolution, cross-sectional images of the retina in a non-invasive manner. These images can be essential for diagnosing and monitoring eye conditions.  In any bioimaging—either retinal or in-vivo imaging that takes place inside the human body—devices ...

MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request.  Why this matters: Microbes, or microorganisms, are all around us and play an important role in bodily functions. MSU researchers found that microbes can also impact brain development. This work is significant because modern obstetric practices like peripartum antibiotic use and Cesarean delivery disturb the microbiome of mothers and newborns. EAST LANSING, Mich. – New research from Michigan State University finds that microbes play an important role in shaping early brain development, specifically in a key brain region that controls stress, social behavior, and vital body ...

NEW YORK, NY (Aug. 13, 2025)--For a few dozen people in the world, the downside of living with a rare immune condition comes with a surprising superpower—the ability to fight off all viruses.   Columbia immunologist Dusan Bogunovic discovered the individuals’ antiviral powers about 15 years ago, soon after he identified the genetic mutation that causes the condition.  At first, the condition only seemed to increase vulnerability to some bacterial infections. But as more patients were identified, its unexpected antiviral benefits became ...

Alexandria, VA – The International Association for Dental, Oral, and Craniofacial Research (IADR) and the American Association for Dental, Oral, and Craniofacial Research (AADOCR) have announced the publication of a new study in JDR Clinical & Translational Research that demonstrates that arginine dentifrices reduce dental caries in children with active caries as much as, or more than, a sodium fluoride dentifrice, depending on the arginine concentration. Dental caries remain a significant oral health burden globally. Scientific evidence has demonstrated the dose-dependent, anticaries action of fluoride; however, ...

Aug. 11, 2025 MSU has a satellite uplink/LTN TV studio and Comrex line for radio interviews upon request.                                           Why this matters: A new MSU study shows that simple, hands-on activities, such as writing letters and pointing out words in daily life, are the most effective way to build early reading skills. Both children with and without speech and/or language impairments experienced literacy gains from print-related activities; however, ...

Reston, VA (August 13, 2025) A new study from Denmark shows for the first time that men with biochemically recurrent prostate cancer who undergo PSMA PET/CT before salvage radiotherapy have improved survival rates compared to those who do not. Using data collected nationwide over a period of eight years, researchers confirmed that PSMA PET/CT is a valuable tool for identifying patients who are likely to benefit from salvage radiotherapy. This research was published in the August issue of The Journal of Nuclear Medicine. Biochemical recurrence after radical prostatectomy occurs in up to 40 percent of prostate cancer patients and salvage radiotherapy ...

EMBARGOED FOR RELEASE UNTIL 4:00 P.M. ET, WEDNESDAY, AUGUST 13, 2025. Highlights: The study included 100 professional athletes who participated in combat sports. Growing up in under-resourced neighborhoods was linked to thinner areas of the brain—a possible early sign of neurodegeneration. Athletes from highly disadvantaged neighborhoods had smaller brain volumes in areas important for movement and memory, including the thalamus, cerebellum and hippocampus. This link remained even after accounting for factors such as race and ethnicity, income and number of fights. The findings support a broader understanding of brain health—one that includes social and environmental ...

WASHINGTON –   A key discovery about the impact of stroke on a person’s ability to read reveals why a deficit occurs – a finding that presents a possible opportunity for new therapeutic strategies to help people recover one of the most important life skills. It’s long been known that people who experience a stroke can struggle with reading, but researchers weren’t clear exactly why. Now, a new study, led by researchers at Georgetown University, reveals that strokes can rob a person’s ability to use the meaning of words to help them recognize the words when reading.  “We usually ...

A Phase 1 human clinical trial to treat chronic spinal cord injury, the first of its kind in the world, has commenced to test the efficacy and safety of a revolutionary new treatment using nasal cells. The Griffith University trial has been three decades in the making and involves taking olfactory ensheathing cells, which are specialised cells involved in our sense of smell, from the nose as they have numerous therapeutic properties for repairing and regenerating nerves.

Scientists at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) have shown that 18FDG-PET, an imaging technique widely used to study other conditions, can also be used to monitor atherosclerosis by measuring cellular metabolism within arterial plaques. The findings, published in Science Translational Medicine, could improve the clinical management of this disease and accelerate the development of new treatments. Atherosclerosis—the underlying cause of most heart attacks and strokes—is a silent disease that progresses over many years without symptoms. The disease is characterized by the accumulation of fatty ...

In a survey study of more than 1,000 U.S. adults who were in committed, heterosexual relationships during the first year of the COVID-19 pandemic, parents were more likely than non-parents to report an increased desire for infidelity since before the pandemic, and were also more likely to report having actually cheated on their partner during the pandemic. Dr. Jessica T. Campbell of Indiana University Bloomington, U.S., and colleagues present these findings in the open-access journal PLOS One on August 13, 2025. Prior research has suggested that COVID-19 pandemic ...

Clinicians are more likely to indicate doubt or disbelief in the medical records of Black patients than in those of White patients—a pattern that could contribute to ongoing racial disparities in healthcare. That is the conclusion of a new study, analyzing more than 13 million clinical notes, publishing August 13, 2025 in the open-access journal PLOS One by Mary Catherine Beach of Johns Hopkins University, U.S. There is mounting evidence that electronic health records (EHR) contain language reflecting the unconscious biases of clinicians, and that this language may undermine the quality of care that patients receive. In the new study, researchers analyzed ...

A drought lasting 13 years and several others that each lasted over three years may have contributed to the collapse of the Classic Maya civilisation, chemical fingerprints from a stalagmite in a Mexican cave have revealed. A detailed analysis of oxygen isotopes in the stalagmite allowed a team of researchers, led by the University of Cambridge, to determine rainfall levels for individual wet and dry seasons between 871 and 1021 CE, which overlaps with the Terminal Classic period of Maya civilisation. This is the first ...

Research from scientists at University of California San Diego School of Medicine have shed new light on an age-old question: what makes the human brain unique? The team’s discovery comes from their investigation of human-accelerated regions (HARs) — sections of the human genome that have accumulated an unusually high level of mutations as humans have evolved. There is a lot of scientific interest in HARs, as they are hypothesized to play an essential role in conferring human-specific traits, and ...

Researchers predict that future climatic change is likely to cause declines in reindeer abundances and their distribution at rates rarely seen over the last 21,000 years. Reindeer, also known as caribou in North America, are an Ice Age species that have survived many episodes of Arctic warming. They are uniquely adapted to Arctic environments, where they regulate ecosystems and sustain the livelihoods of many Indigenous Peoples. Despite being one of the most abundant herbivores in the Arctic, climate change has contributed to a loss of nearly two-thirds of their global abundance over the last three decades. An international team of researchers, led by the University of ...

ITHACA, N.Y. - Cornell University research offers a number of alternatives to neonicotinoids (neonics) that might work for farmers who grow large-seeded vegetable crops such as snap bean, dry bean and sweet corn. This class of insecticides has devastating ecological impacts, especially to pollinators, beneficial insects and aquatic invertebrates.   “We wanted to find other options for growers to protect their vegetable crops from major pests. The impetus was to identify new products including those in the registration pipeline,” said Brian Nault, professor of entomology. “My program ...

In the selection of specialty coffees, those that score above 80 points in blind tests are free of physical and sensory defects. Greenish-colored beans are known to give the drink an astringent taste, which is described as harsh, pungent, and dry. These beans are therefore discarded, along with broken, black, burnt, pitted, or undersized beans. However, in a study published in the journal Food and Bioprocess Technology, researchers from the Federal University of Uberlândia (UFU) in Patos de Minas (state of Minas Gerais, Brazil) conducted a series of fermentations with ripe and ...
