Phys.org / The high‑tech shipbuilding methods that helped Vikings dominate the seas
Images of the sleek keels, elegant planks, and dragon-headed prows of Viking longships have been reproduced countless times on postcards, book covers, souvenirs and in television shows and movies.
Phys.org / Rising seasonal sea-level swings are under-reported, but could have a major impact
Sea levels are rising not only on average, but also in their seasonal fluctuations. This is a lesser-known trend that could have major consequences for mudflats, salt marshes and other coastal ecosystems. Researchers from ...
Phys.org / Chemists discover and isolate a new boron–oxygen molecule
Oxygen is a cornerstone of chemistry, largely because it is so good at building the organic molecules that make up our world. Some oxygen-based compounds called peroxides are famous for being highly reactive—they act like ...
Phys.org / Astronomers directly detect how turbulence between stars distorts light
Astronomers led by the Center for Astrophysics | Harvard & Smithsonian (CfA) have made the first direct detection of turbulence distorting light in the interstellar medium. The findings will help scientists achieve clearer ...
Phys.org / Engineered exosomes reverse sleep deprivation brain damage in mice
Sleep is a vital physiological process that allows humans and other animals to restore both the mind and body, while also consolidating memories, clearing out toxins and regulating their metabolism. Several past studies showed ...
Phys.org / Quantum geometry provides theoretical limits on measurable properties of solids
Two RIKEN physicists have established new theoretical limits for experimentally measurable quantities by viewing solids through a lens of quantum geometry. Their results shed light both on the physics of solids and on quantum ...
Phys.org / Statistical technique could uncover secrets of 'ringing' black holes
Researchers have developed a technique to analyze how black holes "ring" when they collide and merge: one of the universe's most dramatic events. When black holes merge, the collision produces a new, larger black hole that ...
Medical Xpress / Myelin emerges as an active regulator of brain plasticity, not only a structural insulator
A study by Professor Carlos Matute of the EHU reinforces a paradigm shift in neuroscience: Myelin goes from being a structural element to being an active component of brain function. Published in Trends in Molecular Medicine, ...
Phys.org / 'Learning recession' in US schools predates pandemic: Report
A new analysis of student test scores reveals that American schools were in a "learning recession" for seven years before the COVID-19 pandemic, with student test scores in math and reading on a steady decline since 2013. ...
Medical Xpress / New study challenges the idea that testosterone drives risk-taking behavior
Men are more likely to take risks in tricky situations than women, but whether there is an inherent biological reason behind it is a question researchers have been asking for quite some time. A popular theory suggests that ...
Phys.org / From molecules to meaning: A search engine developed for the chemistry of life
An international team led by researchers at University of California San Diego and University of California, Riverside has developed a free, web-based platform designed to make public metabolomics data more accessible. By ...
Phys.org / The dam dilemma: How to build anew without repeating old harms
As the U.S. and other countries expand clean energy, large hydropower dams, often seen as a reliable renewable solution, can come with significant environmental and social costs if not planned thoughtfully.
