In brief: New research offers the most comprehensive look yet at how global crop yields are likely to change as the planet warms. After adjusting for how real farmers adapt, researchers estimate global yields of calories from staple crops in a high-emissions future will be 24% lower in 2100 than they would be without climate change.  U.S. agriculture and other breadbaskets are among the hardest-hit in the study’s projections, while regions in Canada, China, and Russia may benefit. The global food system faces growing risks from climate change, even as farmers ...

Inspired by naturally occurring air bubbles in glaciers, researchers have developed a method to encode messages in ice. Publishing June 18 in the Cell Press journal Cell Reports Physical Science, the paper explains how the team encoded frozen messages in binary and Morse code by manipulating the size and distribution of bubbles in ice. The method could be used to store short messages in very cold regions such as Antarctica and the Arctic, where conventional information storage is difficult or prohibitively expensive.   “In naturally cold regions, the use of trapped air bubbles as a means of message delivery and storage uses less energy than ...

Today, all non-Africans are known to have descended from a small group of people that ventured into Eurasia after around 50 thousand years ago. However, fossil evidence shows that there were numerous failed dispersals before this time that left no detectable traces in living people. In a paper published in Nature this week, new evidence for the first time explains why those earlier migrations didn’t succeed. A consortium of scientists led by Prof. Eleanor Scerri of the Max Planck Institute of Geoanthropology in Germany, and Prof. Andrea Manica of the University of Cambridge has found that before expanding into Eurasia 50 ...

About The Study: This study identified distinct trajectories of addictive use of social media, mobile phones, and video games from childhood to early adolescence and found links to suicidal behaviors, suicidal ideation, and worse mental health outcomes. High or increasing addictive use trajectories were common. Addictive screen use trajectories warrant further study regarding potential use for clinical evaluation of risk and for the design and testing of interventions to improve youth mental health. Corresponding ...

“What Denisovans looked like, despite their genetic contributions to present-day East Asians and Oceanians?” This is one of the most important questions that has arisen since the discovery of the Denisovans 15 years ago. Now, recent research by a team led by FU Qiaomiei from the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences, and JI Qiang of Hebei GEO University has helped answer this question by confirming that a nearly complete hominin skull discovered near Harbin belongs to the Denisovan lineage. It dates back to at least 146,000 years ...

New research found that youth who become increasingly addicted to social media, mobile phones or video games are at greater risk of suicidal thoughts, suicide attempts and emotional or behavioral issues. The study, published June 18 in JAMA, was led by researchers at Weill Cornell Medicine, Columbia University and University of California, Berkeley. Unlike previous studies that focused on total screen time at one point in a child’s life, this study looked at how young people’s patterns of compulsive or “addictive” use changed over time. These patterns included ...

In a world-first discovery, researchers have shown that Australia’s iconic Bogong moth uses constellations of stars and the Milky Way to navigate hundreds of kilometres across the country during its annual migration – making it the first known invertebrate to rely on a stellar compass for long-distance travel. The landmark study, published today (Thursday 19 June) in Nature, reveals how this unassuming nocturnal moth combines celestial navigation with Earth’s magnetic field to pinpoint a specific ...

SCOTTSDALE, Ariz. — June 18, 2025 — More patients are surviving and recovering from the most common and severe form of brain stroke thanks to data-driven treatment methods based on the amassing of more than 1 million variables in an HonorHealth Research Institute program known as HALO, which stands for HonorHealth Acute neuroLogical Outcome. Ischemic stroke, as opposed to bleeding caused by blunt force trauma, occurs when a blood vessel supplying oxygen to the brain is obstructed because of a blood clot — typically formed in the heart or an artery in the neck. Such blockages, responsible for 87% of all strokes, often result in permanent disability ...

This review synthesizes current knowledge on these biomarkers, proposing an integrative model ...

Astronomers have created a galactic masterpiece: an ultra-detailed image that reveals previously unseen features in the Sculptor Galaxy. Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), they observed this nearby galaxy in thousands of colours simultaneously. By capturing vast amounts of data at every single location, they created a galaxy-wide snapshot of the lives of stars within Sculptor. "Galaxies are incredibly complex systems that we are still struggling to understand," says ESO researcher Enrico Congiu, who led a new Astronomy & Astrophysics study on Sculptor. Reaching ...

Most treatments for Parkinson’s disease (PD) only slow disease progression. Early intervention for the neurological disease that worsens over time is therefore critical to optimize care, but that requires early diagnosis. Current tests, like clinical rating scales and neural imaging, can be subjective and costly. Now, researchers in ACS’ Analytical Chemistry report the initial development of a system that inexpensively screens for PD from the odors in a person’s ear wax. Previous research has ...

COLUMBUS, Ohio – The personal credit scores of top-level corporate executives can help explain their decision making in the corporate environment, at least when it involves evaluating risk, a new study suggests.   Researchers at The Ohio State University conducted an experiment with a national sample of high-level executives and found that those with subprime credit scores tended to be “yes persons” – even when it was counterproductive.   In contrast, executives with prime ...

Humans have tens of thousands of genes, many of which produce proteins essential to basic bodily functions. The KCNT1 gene, for example, codes for a protein that maintains normal electrical activity in the brain and helps neurons communicate. But genes don’t always function perfectly. For many people, a mutation of the KCNT1 gene causes no symptoms. For others, it can lead to dysfunction of neuronal activity causing learning disabilities, difficulty communicating, and a lifetime of treatment-resistant seizures. Epileptic disorders caused by mutations in KCNT1 affect ...
