Novel DNA nanoplatform offers hope for chronic gum disease

Millions of people worldwide live with periodontitis, a chronic gum disease that can progressively destroy the tissues and bone supporting the teeth despite conventional treatment.

Long-term study proves brain stimulation safely restores touch

What if people who have lost the ability to feel their hands could get that sense back - not through a prosthetic glove, but through tiny pulses of electricity delivered directly to the brain?

New method detects early skin collagen damage before visible signs

An international team led by researchers at Hiroshima University has developed a new way to detect subtle, early-stage changes in human skin collagen before any visible signs of damage appear.

Scientists show how sweeteners slow the growth of certain gut bacteria

Cambridge researchers have shown how commonly-used sweeteners slow the growth of certain gut bacteria.

Limited attention can make rare events seem more likely over time

Researchers developed a theoretical model showing how attention to unusually positive or negative experiences can systematically distort long-term beliefs about probability. The model suggests that rare events may remain overweighted even after extensive learning, while ordinary observations receive less influence.

Sleeping longer may signal early Alzheimer's-related brain changes

Regularly sleeping long hours each night is associated with higher levels of an Alzheimer's-related protein in the blood, even accounting for other health factors, suggests a new study from UT Health San Antonio, the academic health center of The University of Texas at San Antonio.

Researchers uncover new T cell attack mechanism against acute myeloid leukemia

Researchers at The University of Texas MD Anderson Cancer Center have discovered a new way in which T cells attack acute myeloid leukemia (AML) cells, which may help explain why AML is particularly sensitive to immune-based treatments and could guide the development of future cancer immunotherapies.

Walking protein structure explains how cells activate molecular motors

A nerve cell resembles a vast tree with branches that communicate with thousands of other cells. To function, it depends on a motor protein that walks on two legs, hauling urgent cargo from the center of the cell to the faraway tips of every branch.

Genome-mining tool reveals new antibiotic hidden in a silent gene cluster

Researchers developed DiscERN, a genome-mining platform that combines four complementary algorithms to identify evolutionarily related biosynthetic gene clusters and prioritize candidates for experimental study. The approach revealed discomycin A, a previously unknown calcium-dependent lipopeptide antibiotic with potent activity against several Gram-positive bacteria.

Fruit fly study uncovers gene behind seasonal winter dormancy

Researchers at Washington State University have discovered a molecular "winter lock" that keeps animals in a less active winter state until favorable conditions return, a discovery that could improve pest control and lead to a better understanding of seasonal health conditions in humans.

Bile acid buildup linked to aggressive breast cancer progression

A buildup of bile acids caused by an unhealthy gut can drive breast cancer to other parts of the body, new University of Virginia Comprehensive Cancer Center research reveals.

Scientists develop ultrathin skin sensors for seamless health tracking

While wearable health sensors are becoming increasingly common, current iterations are awkward to wear.

New drug candidate improves Parkinson's treatment in animal models

For many people with Parkinson's disease, the body stops moving the way it used to. A hand may tremble at rest. Muscles may stiffen.

Brain’s immune cells play key role in maintaining stability of neuronal networks in Alzheimer's disease

Researchers at Trinity College Dublin have discovered that microglia – the main immune cells of the brain – play a critical role in maintaining the stability of neuronal networks in Alzheimer's disease.

AI model predicts effective immunotherapy combinations for liver cancer

Using computational tools, researchers from the Johns Hopkins Kimmel Cancer Center and the Johns Hopkins University School of Medicine have developed a method to predict which patients with a primary liver cancer called hepatocellular carcinoma (HCC) would most benefit from combination treatment using immunotherapy and a targeted therapy that blocks the growth signals that the tumor depends on.

New machine learning model improves cholesterol calculation accessibility

The Martin-Hopkins equation to assess low-density lipoprotein (LDL) cholesterol levels in blood samples has been used by laboratories in the U.S. and other countries to guide efforts to lower cardiovascular disease risk.

Ketogenic diet may increase small intestine cancer risk in mice

A high-fat, low-carbohydrate diet, also called a ketogenic diet, can help some people lose weight by forcing their bodies to burn fat for fuel instead of sugar.

Targeted nanoparticles destroy tumor cells by triggering cuproptosis

A promising cancer treatment strategy called cuproptosis, which uses copper-dependent cell death to eliminate tumor cells, faces a major challenge: many approaches require adding external copper, potentially increasing toxicity beyond the tumor.

New photoswitchable drugs restore light perception in blind animals

Blinding diseases caused by the degeneration of photoreceptors, such as age-related macular degeneration (AMD) and retinitis pigmentosa (RP), affect 200 million people worldwide and represent the leading causes of visual impairment and blindness.

Study sheds light on the prognostic value of blood test for predicting cognitive impairment risk

A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged around the extent to which such tests can accurately predict whether a cognitively healthy individual will go on to develop cognitive impairment-a key symptom of Alzheimer's disease.
