Helping out your neighbor or minding your own business? A challenging choice with different benefits for each decision. Game theory provides guidance in making such choices -- from a theoretical perspective. Novel findings reveal new network structures that enhance cooperation throughout a system. These insights have potential applications also in biology. Read more ›

Scientists report on new insights into the mechanisms of 'Niemann-Pick type C' (NPC), a rare neurodegenerative disease associated with dementia that can manifest as early as childhood. Their findings, based on studies in mice, cell cultures and patients, emphasize that neuroinflammation, which is mediated by the brain's immune system, plays a crucial role in NPC. Read more ›

Over the past two decades, scientists discovered that the majority of melanic wing color variants are controlled by a single genomic region surrounding the protein-coding gene 'cortex'. It was assumed, then, that cortex was the melanic color switch. A team of international researchers has now discovered that cortex does not affect melanic coloration. Instead, a previously ignored microRNA (miRNA), is the actual color switch. Read more ›

The U.S. is forecasted to fall in its global rankings below nearly all high-income and some middle-income countries. Drug use disorders, high body mass index, high blood sugar, and high blood pressure are driving mortality and disability higher across the U.S. Future scenarios for health outcomes identify the states that are forecasted to gain ground, face stagnation, or grow worse. Scientific evidence underscores the urgent need to prioritize public health... Read more ›

Scientists have 'turned up the heat' on how repeated outbreaks of coffee wilt disease threatened arabica and robusta varieties of our favorite daily coffee brew. The scientists say the fungal pathogen Fusarium xylarioides continues to pose a significant threat to coffee production and incomes across sub-Saharan Africa. Read more ›

Rising sea levels, melting glaciers, heatwaves at sea -- 2023 set a number of alarming new records. The global mean temperature also rose to nearly 1.5 degrees above the preindustrial level, another record. Seeking to identify the causes of this sudden rise has proven a challenge for researchers. After all, factoring in the effects of anthropogenic influences like the accumulation of greenhouse gases in the atmosphere, of the weather phenomenon... Read more ›

Scientists have uncovered surprising ways transcription factors, the genetic switches for genes, regulate plant development. Their findings reveal how subtle changes in a lipid-binding region called the START domain can dramatically alter gene regulation, paving the way for advancements in crop engineering, synthetic biology, and precision gene therapies.

Stem cell transplantation is used to treat several types of blood cancers, but carries the risk of a life-threatening side effect called graft-versus-host disease. Results from a clinical trial showed adding the investigational drug itacitinib to standard care for 'half-matched' stem cell transplantation may reduce rates of the disease, in which the donor's stem cells attack the patient's healthy tissues.

Researchers have found a new receptor for nerve growth factor that plays an important role in pain signaling, even though it does not signal on its own, according to a new study. The findings hold promise for finding new treatments for arthritis and other forms of inflammatory and cancer pain, without the side effects that led recent therapies to fail in clinical trials.

A groundbreaking phase one clinical trial explored a novel cell-based immunotherapy for breast cancer. The study focuses on a new treatment approach that aims to harness the body's immune system to enhance patient responses and reduce the need for conventional chemotherapy and its associated toxicities. The trial involved 12 patients with locally advanced stage I-III HER2 breast cancer. Read more ›

Researchers describe two enzymes newly identified for their roles in regulating macropinocytosis, a process cancer cells use to snatch extra nutrients from the jelly-like substance between cells. This allows tumors to fuel their growth even when they consume more energy and other resources than they can acquire from nearby blood vessels. Read more ›

A new method of analyzing mammograms identified individuals at high risk of developing breast cancer more accurately than the standard, questionnaire-based method did. The new method, powered by artificial intelligence, could help diagnose cancer earlier and guide recommendations for earlier screening, additional imaging or risk-reducing medications. Read more ›

As climate change accelerates, scientists are sounding the alarm about its potentially devastating impact on the world's food supply. Researchers warn that without rapid changes to how we develop climate-resilient crops, we could face widespread food shortages leading to famine, mass migration, and global instability. Read more ›
