Scientists have discovered new evidence that early human ancestors used fire in South Africa’s Wonderwork Cave between 1.07 million and 1.79 million years ago. The discovery traces back one of the earliest records of fire use associated with humans and provides new clues about how our ancestors first learned to harness fire. Using newly developed technology that can detect signs of combustion in fossilized bones, researchers repeatedly identified signs of fire deep within the cave. Because these traces were found far beyond the reach of natural wildfires, the discovery suggests that early humans intentionally brought naturally occurring fires into the…

While women who met Nordic whole grain recommendations for years were less likely to develop breast cancer, research has found that not all whole grain foods affect cancer risk in the same way. Study: Long-term whole grain intake in line with the 2023 Nordic Nutritional Recommendations and breast cancer risk in a population-based cohort of women. Image credit: marilyn barbone/Shutterstock.com According to a recent study published in european nutrition journalin line with the 2023 Nordic Nutritional Recommendations, women with a long-term intake of at least 90g of whole grains per day had a lower risk of breast cancer than women…

A major new tool for X-ray research has started operating at BESSY II. Developed jointly by HZB, MPI-CEC (Mülheim an der Ruhr, Germany), and NIST (Boulder, Colorado, USA), this instrument is the first and only TES spectrometer to operate at a synchrotron facility in Europe. This new system dramatically increases photon detection efficiency, outperforming traditional wavelength-dispersive X-ray emission spectrometers by a factor of 100 to 1000. The researchers plan to use this system to study the electronic properties of atomically thin materials, nanostructures, and highly dilute atomic and molecular samples. The research team is currently soliciting research proposals from the…

Why are more young people developing cancer? A major new study suggests that accelerated biological aging may be fueling the rise in cancers diagnosed in people under the age of 55, providing new clues to one of medicine’s fastest-growing mysteries. Research: Biological aging and generational alternation in early cancer risk. Image credit: Ground Picture/Shutterstock.com New research published in natural medicine Association between accelerated biological aging and early cancer risk in young people. Biological age emerges as a cancer risk marker The incidence of young-onset cancers diagnosed in adults younger than 55 years has increased significantly over the past 30 years,…

FairJourney Bio (“FJBio”), a global antibody discovery expert, has entered into a partnership with AbTherx, Inc. to bring transgenic mouse-based antibody discovery in-house. The agreement gives the company access to AbTherx’s Atlas™ Full Human Diversity (FHD) and Common Light Chain (cLC) mouse technology, completing a discovery route that partners can run end-to-end entirely within FJBio’s integrated workflow. The partnership enables the program to move as a single effort, from vaccination through single B cell screening and optimization, to candidate stability assessment and cell line development, and is now executed by one team across FJBio’s global locations in Porto (Portugal), Cambridge…

Scientists have long believed that the recipe for producing queen bees is simple. By feeding the developing larvae with plenty of royal jelly, the queen bee becomes the ruler of the colony. New research suggests the reality is much more complex. The researchers discovered that future queen bees are raised in specially designed nurseries created by young worker bees. These chambers provide unique wax, a warm environment, and dedicated care to help the larvae develop into healthy queens. The survey results were published in a magazine natureshowing that the structure known as the queen cell, also known as the “royal…

According to a major review, AI can help clinicians work faster and more accurately, but only if the system is built around real-world clinical workflows, coordinated trust, and clear accountability. Research: Human-AI collaboration in healthcare: A scoping review. SWK Stock / Shutterstock New scoping review available as journal article npj digital medicine We discuss recent evidence regarding the utility of human-artificial intelligence (AI) collaboration in healthcare. background Applications of artificial intelligence (AI) in healthcare are rapidly increasing across clinical tasks such as medical documentation, triage and task prioritization, image interpretation, and care coordination. However, in medical settings that involve important…

Many people in the UK who are considered to be at high risk of vitamin D deficiency may not be getting enough nutrients throughout the year, according to new research. The findings cast doubt on the widely held belief that simply spending time in the summer sun can restore healthy vitamin D levels. Researchers from Newcastle University’s Human Nutrition and Exercise Research Center analyzed vitamin D levels in around 300 people across the north of England. Their results suggest that a significant number of people may be vitamin D deficient year-round without realizing it, which can impact bone health, overall…

Exercise may have a modest but measurable protective effect against weight gain after dieting or bariatric surgery, but the evidence is less clear as to whether it significantly reduces fat mass. Research: Effects of exercise interventions on weight regain after weight loss: A systematic review and meta-analysis. Image credit: Dragon Images / Shutterstock In a recent study published as a press article in the journal scientific reportA group of researchers evaluated whether exercise intervention during the weight maintenance phase could reduce weight regain after successful weight loss. background Many people who successfully lose weight eventually regain some of that weight,…

New health screening data from South Korea suggest that while antidiabetic treatment administered promptly after the threshold for type 2 diabetes is crossed may improve survival rates, cardiovascular benefits remain promising but unproven. Study: Timing of antidiabetic drug initiation and risk of cardiovascular events and death. Image credit: Anastasiya Artcomma / Shutterstock In a recent study published in the journal JAMA network openresearchers investigated the association between the timing of antidiabetic drug (ADM) initiation and the risk of major major cardiovascular events (MACE) and death in people who newly reach laboratory diagnostic thresholds for type 2 diabetes (T2D). T2D is…
