Phys.org / How Ramanujan's formulae for pi connect to modern high energy physics
Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More recently, scientists have ...
Phys.org / Natural language found more complex than it strictly needs to be—and for good reason
Human languages are complex phenomena. Around 7,000 languages are spoken worldwide, some with only a handful of remaining speakers, while others, such as Chinese, English, Spanish and Hindi, are spoken by billions. Despite ...
Phys.org / Quantum technology moves from lab to life, but widespread use remains years away
Quantum technology is accelerating out of the lab and into the real world, and a new article argues that the field now stands at a turning point—one that is similar to the early computing age that preceded the rise of the ...
Phys.org / Physicists create 'quantum wire' where mass and energy flow without friction or loss
In physical systems, transport takes many forms, such as electric current through a wire, heat through metal, or even water through a pipe. Each of these flows can be described by how easily the underlying quantity—charge, ...
Phys.org / Ancient dirty dishes reveal decades of questionable findings
Olive oil is the Swiss army knife of foodstuffs. It can dress salads, sauté vegetables, even grease squeaky hinges. And for archaeologists, its ubiquitous presence in excavated pottery offers a window into the economic, ...
Medical Xpress / Early Parkinson's predictor found in daily step count
Oxford's Big Data Institute and Nuffield Department of Population Health report that daily step counts may help identify who will later be diagnosed with Parkinson's disease, with lower activity patterns acting as an early ...
Phys.org / 24,000 times more harmful to the climate than CO₂: Measurements reveal SF₆ gas emissions in Germany
Sulfur hexafluoride (SF6) is a chemically stable, colorless, odorless, and non-toxic gas. It is used all over the world, primarily as an insulating and protective gas in electrical switchgear within medium- and high-voltage ...
Phys.org / Alkaline-loving microbes could help safeguard nuclear waste buried deep underground for thousands of years
Billions of alkaline-loving microbes could offer a new way to protect nuclear waste buried deep underground. This approach overcomes the limitations of current cement barriers, which can crack or break down over time.
Phys.org / Unbee-lievable: Botswana elephants not easily fooled as scientists seek solution to human-elephant conflict
In Botswana, coexisting with the country's 130,000 elephants can be a daily negotiation. For rural families, tending a crop means hoping these "gentle giants" don't wander through and cause damage while searching for food ...
Phys.org / Debris disk gallery shows tell-tale signs of asteroids and comets in distant solar systems
Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.
Phys.org / Dynamic duo of bacteria could change Mars dust into versatile building material for first human colonists
Since humanity's first steps on the moon, the aspiration to extend human civilization beyond Earth has been a central objective of international space agencies, targeting long-term extraterrestrial habitation. Among the celestial ...
Phys.org / Ten versions of Earth's future can help us hunt for technosignatures
Searching for technosignatures—signs of technology on a planet that we can see from afar—remains a difficult task. There are so many different factors to consider, and we only have the technological capabilities to detect ...
