Phys.org / Sea surface temperature biases shift the North Pacific jet stream southward, study finds
Climate models are numerical models used to project future climate change. They simulate the climate from the present into the future by calculating changes in the atmosphere, ocean and other components of the climate system. ...
Phys.org / North Korea's nuclear testing may have triggered hundreds of earthquakes over several years
Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes ...
Phys.org / Medieval Chinese skeleton may reveal first evidence of a brutal punishment
Ancient Chinese authorities used many creative ways to punish people, often with methods designed to mark them for life. One brutal example mentioned repeatedly in historical texts is cutting off a person's nose. However, ...
Phys.org / Discovery of CRISPR's long lost ancestor may expand gene-editing toolkit
CRISPR may be a powerful technology for gene editing, but the system existed in bacteria long before scientists began using it. For billions of years, CRISPR has acted as a natural immune system in bacteria and other microbes, ...
Phys.org / Physicists extend the search for quantum black holes at the LHC
Physicists at UC Santa Barbara have extended the search for evidence of microscopic black holes produced at the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN). The formation of these ...
Phys.org / Greenland's Qaanaaq Ice Cap has lost enough ice to produce a layer of water about 8 meters deep
Each summer, researchers from Hokkaido University returned to the Qaanaaq Ice Cap in northwestern Greenland to measure changes in the ice surface using aluminum poles drilled into the ice. Their 13-year record shows how the ...
Phys.org / Stacked 2D materials reveal room-temperature multiferroicity and voltage-controlled magnetism
Multiferroics are materials that simultaneously exhibit two or more ferroic orders—stable arrangements of physical properties that can be switched using an external stimulus. These materials could be highly advantageous for ...
Phys.org / New thermal insulator outperforms any material found in nature
Researchers have engineered a new material that is an extreme thermal insulator, is exceptionally stiff and can be printed as a thin film at large scales. The material has one of the lowest thermal conductivity profiles of ...
Tech Xplore / Bio-inspired whiskers enable tiny drones to navigate in darkness using touch
Rats and mice can scurry through dark, tight spaces with ease—in caves, underground burrows, buildings or sewers. Their superpower is their whiskers. Now, tiny autonomous drones could soon navigate through darkness, dust ...
Phys.org / To read 2,000-year-old burned scrolls, scientists burn their own
Douglas Seiler painstakingly sourced papyrus and reed pens from Egypt and traditional lampblack ink from Japan, then paid some high school students to inscribe the papyrus with lines from Star Wars and the Bible and a quote ...
Medical Xpress / Eating more eggs and peanuts while pregnant does not prevent infant allergies, clinical trial finds
Millions of people around the globe might never know the taste of a PB&J sandwich or crème brûlée because of severe peanut and egg allergies. For a long time, avoiding exposure to allergy-causing foods early in life was considered ...
Medical Xpress / Tiny tactile sensor could help distinguish tissues during minimally invasive surgery
Minimally invasive surgery is a promising approach that allows doctors to intervene inside the body through small incisions, typically using advanced instruments. These can include small robotic instruments controlled by ...
