In the wake of recent wildfires that have ravaged northern and central California, a new study finds that the severity of fire activity in the Sierra Nevada region has been sensitive to changes in climate over the past 1,400 years. The findings
A new experimental growth factor therapy appears to prevent a worsening of osteoarthritis by increasing the thickness of cartilage in the knee joint and preventing further loss, according to results from an early clinical trial that were published today in the Journal of the American Medical Association.
When a heart attack occurs, muscle in the heart tissue can be scarred, interfering with electrical activity necessary for healthy heart function. Using artificial materials to patch or rebuild damaged parts has been tried but only recently has work focused on the electrical properties needed for proper cardiac operation. In this week’s APL Bioengineering, investigators review the use of electrically conductive biomaterials for heart repair and treatment.
During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous -- essentially a thick, sticky and semifluid mess. One way to outmaneuver this problem, reported in Physics of Fluids, is a viscoplastic lubrication technique.
In a new study published in EBioMedicine, researchers with Moffitt Cancer Center’s Donald A. Adam Melanoma and Skin Cancer Center of Excellence reveal that differences at the single-cell level can predict responses to initial BRAF inhibitor therapy, and that leveraging these differences may improve patient outcomes.
Scientists have made genetic data publicly available for bacteria that might be lurking inside the gut walls of patients chronically affected with severe Crohn’s disease. By studying a surgically removed, damaged bowel from a patient, researchers were able to culture bacteria from a special form of microscopic lesions that they earlier discovered and that can be present within the gut wall of the inflamed bowel in Crohn’s disease. After growing the bacteria in their laboratory, they chose one representative species, and performed a complete genome sequence analysis that could hold clues into how the slow and damaging microlesions form.
Notre Dame researchers found that although coastal homeowners may perceive a worsening of climate change-related hazards, these attitudes are largely unrelated to a homeowner’s expectations of actual home damage.
University of Utah electrical and computer engineering researchers have developed a new kind of optical lens that is much thinner and lighter than conventional camera lenses that also works with night imaging. That could be a boon for smartphone cameras with those unsightly lens bumps as well as for drones and night vision cameras for soldiers.
Scientists from Rutgers University and around the world have discovered an antibiotic produced by a soil bacterium from a Mexican tropical forest that may help lead to a “plant probiotic,” more robust plants and other antibiotics. Probiotics, which provide friendlier bacteria and health benefits for humans, can also be beneficial to plants, keeping them healthy and more robust. The new antibiotic, known as phazolicin, prevents harmful bacteria from getting into the root systems of bean plants, according to a Rutgers co-authored study in the journal Nature Communications.
The immune system relies on B cells and their ability to make antibodies against an extremely broad range of pathogens. This broad responsiveness bears some risk, as B cells can also turn against healthy tissue - a phenomenon called autoimmunity. Scientists from the lab of Meinrad Busslinger now reported in the journal "Nature Immunology" how the protein lkaros orchestrates the fine balance between B cell silencing and activation - and thereby controls autoimmunity.
Researchers performed a systematic review and meta-analysis of published data on the effect of electrical stimulation therapies on spinal fusion. They found significant improvement overall in the rates of bone fusion following a course of electrical stimulation in preclinical and clinical studies.
The benefits of breastfeeding for both mother and child are well-recognized, including for late preterm infants (LPI). But because LPI do not have fully developed brains, they may experience difficulties latching and/or sustaining a latch on the breast to have milk transfer occur. This means that these infants are at high risk for formula supplementation and/or discontinuation of breastfeeding.
In a certain sense, physics is the study of the universe’s symmetries. Physicists strive to understand how systems and symmetries change under various transformations.New research from Washington University in St. Louis realizes one of the first parity-time (PT) symmetric quantum systems, allowing scientists to observe how that kind of symmetry — and the act of breaking of it — leads to previously unexplored phenomena.
Over the last two decades, more Americans see people with mental health problems as dangerous and are willing to use legal means to force treatment, according to a new paper by IU Distinguished Professor of Sociology Bernice Pescosolido.
Exposure to violence can negatively impact a person’s physical and psychosocial health, according to two new studies published in the policy journal Health Affairs.
The rate at which Americans died from firearm injuries increased sharply starting in 2015, a new study shows. The change occurred to varying degrees across different states, types of firearm death such as homicide and suicide, and demographics. In all, the US saw a 14% rise in the rate of firearm deaths from 2015 through 2017, compared with the rate seen in the years 1999 through 2014.
Firearm injuries kill 2,500 American children each year. But the nation spends far less on studying what led to these injuries, and what might prevent and treat them, than it spends on other causes of death in children. In fact, on a per-death basis, funding for pediatric firearm research is 30 times lower than it would have to be to keep pace with research on other child health threats.
An increase in behavioral health providers is associated with a slight decrease in gun-related suicides, but the difference is small and points to a need to tackle gun violence in other ways, according to the authors of a new study.
Researchers long wondered how the billions of independent neurons in the brain come together to reliably build a biological machine that easily beats the most advanced computers. All of those tiny interactions appear to be tied to something that guarantees an impressive computational capacity.

Engineers developed silk materials that can wrinkle into nanotextured patterns – including words, textures and images as intricate as a QR code or a fingerprint. The patterns are stable, but can be erased by flooding the surface of the silk with vapor, allowing the it to be printed again. Researchers see many applications in optical electronics
Scientists have revealed how the electrical patterns formed within an embryo initiate a cascade of molecular changes that culminate in the development of cartilage and bone. The study demonstrates that voltage gated calcium channels ‘read’ the electrical pattern, setting off the expression of genes that guide differentiation to mature cells

Researchers from the UCLA Jonsson Comprehensive Cancer Center and other institutions in the U.S., Canada, the United Kingdom and Singapore, have identified 1,178 biomarkers in men’s genomes — the complete set of genetic material inherited from one’s parents — that predict how an individual person’s prostate cancer will grow. The finding suggests that predicting how a person’s cancer will evolve may lie in their inherited DNA.
