Phys.org / To understand the solar cycle, notice how the sun sleeps
The sun is such a constant in our lives that it can be difficult to imagine our star ever changing. But the sun can be quite variable. There are times when its magnetic field is turbulent and generates many sunspots and other ...
Medical Xpress / Drug delivery system slowly releases pain-relieving nerve block over weeks
Most local anesthetics used in medicine last only eight to 12 hours, or a day at most. Now, Boston Children's Hospital researchers have formulated a more effective slow-release injectable drug delivery system that achieved ...
Phys.org / Light beam 'swims' upstream through a quantum fluid by violating Newton's third law
Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
Phys.org / Short 'logic check' warnings may improve how people assess climate arguments
In the climate debate, people are exposed to a lot of different information and opinions. A short warning that an argument may contain a logical fallacy helps people evaluate information more critically.
Phys.org / Superdense neutron star caught feeding on a blue hypergiant's stellar wind
Using data from the Japan–led XRISM (X-ray Imaging and Spectroscopy Mission) observatory, astronomers have directly observed a giant star's outflow, called a stellar wind, being captured by its compact companion and providing ...
Phys.org / Children born today in Europe will live through almost twice as much extreme fire weather as their grandparents
A child born in Europe in 2025 will live through more than three additional years of extreme fire weather compared with someone born in 1950 if we continue with current climate policies, according to new research published ...
Phys.org / Heat waves on land start earlier and develop faster, global analysis reveals
Heat waves over land worldwide are beginning earlier, ending later and occurring over longer seasons, while the first heat wave of the season has recently shifted toward faster onset, according to a new study published in ...
Tech Xplore / Will AI models achieve the ability to improve autonomously? Leading labs say the scenario is near
Once a distant ambition for technology researchers, the prospect of artificial intelligence models teaching themselves autonomously to be more efficient and capable appears ever closer to reality.
Phys.org / Hubble spots an out-of-sync galaxy
Though the spiral galaxy in this new image from the NASA/ESA Hubble Space Telescope seems serene, it hides a chaotic secret. This galaxy is NGC 4698, and it lies about 55 million light-years away in the constellation Virgo. ...
Phys.org / Who benefits from tariffs, according to research
Tariffs are usually debated as trade policy. But a study from the University of Chicago Booth School of Business treats them as something else: a mechanism for redistributing wealth.
Tech Xplore / Anthropic, OpenAI release cheaper AI even as safety fears grow
Anthropic and OpenAI on Tuesday released new, cheaper artificial intelligence models within hours of each other, days after the heads of both companies called for a slowdown in AI development.
Phys.org / What billiard balls reveal about computers and the limits of prediction
When is a billiard ball not a billiard ball? When mathematicians get involved and view a popular game as a model computer.
