Dogs can tell fear from sadness — and scientists saw it in their brains

Dogs are exceptionally skilled at reading human emotions, from smiles and laughter to frowns and tears. Scientists and dog owners have recognized this ability for years, but the biological mechanisms that make it possible have remained largely unknown. A study published August 7 in the Cell Press journal iScience offers…

MIT neuroscientists discover the brain can reason without words

Talking through a difficult problem can help some people organize their thoughts. But according to cognitive neuroscientists at MIT’s McGovern Institute for Brain Research, language itself is not required for logical reasoning. In research published recently in the journal PNAS, a team led by MIT associate professor of brain and…

“Cannot be explained” – New super steel stuns scientists

A team at the University of Hong Kong (HKU) has developed a new type of stainless steel that could overcome a major limitation of conventional stainless steel and potentially lower the cost of producing green hydrogen. Led by Professor Mingxin Huang of HKU’s Department of Mechanical Engineering, the researchers created…

Marine heatwaves are harming human health in surprising ways

Marine heatwaves are increasingly being recognized as more than an environmental problem. New research warns that prolonged periods of unusually warm ocean temperatures can also threaten human physical and mental health. Researchers from Adelaide University and the University of Hong Kong say marine heatwaves should be treated as an important…

King Harold may have lost England by backing the wrong pope

New research from the University of East Anglia suggests that a lost papal letter could change how historians understand the events of 1066 and the Norman Conquest. Surviving excerpts of the letter, preserved in the Vatican archives, point to a major political struggle in Rome that may have influenced the…

Black holes older than the Big Bang could explain dark matter

Black holes created before the Big Bang may have survived into the Universe we see today, according to new research from the University of Portsmouth. These ancient objects could act as “cosmic fossils” and may even help explain dark matter, the invisible material that plays a major role in shaping…

NASA’s moon base is taking shape with 20+ lunar landings planned

NASA is moving ahead with plans for its Moon Base, a durable outpost near the Moon’s South Pole that is intended to support science, technology development, and eventually human operations. A major part of that effort involves commercial partners Blue Origin, Firefly Aerospace, Intuitive Machines, and Voyager Lunar Systems, which…

A simple blood test could detect multiple cancers and reveal where they started

UCLA researchers have created a simple, relatively inexpensive blood test that showed promise in early studies for detecting several types of cancer, multiple liver diseases, and signs of organ problems at the same time. The approach works by examining fragments of DNA that circulate naturally in the bloodstream. Described in…

The secret hidden in these ancient manuscripts isn’t written in ink

Scientists have developed a way to recover cellular material from historic parchment manuscripts without damaging the documents. The technique makes it possible to analyze genetic information preserved in parchment and could reveal new details about trade, farming, and other aspects of life stretching back roughly 1,300 years. Parchment is made…

Exercise may help the aging brain “take out the trash”

Regular exercise may do more than strengthen the body. New research from Victoria University (VU) adds to evidence that physical activity could also play an important role in protecting the brain from age-related decline, including dementia and Alzheimer’s disease. VU researcher Dr. James Broatch led the analysis, which examined how…
