Cracking the ice code
(Phys.org) —What happened the last time a vegetated Earth shifted from an extremely cold climate to desert-like conditions? And what does it tell us about climate change today?
Orion's hidden fiery ribbon
(Phys.org) —This dramatic new image of cosmic clouds in the constellation of Orion reveals what seems to be a fiery ribbon in the sky. This orange glow represents faint light coming from grains of cold ...
Why don't beetles freeze in the winter?
For 37 years, Queen's University Biochemistry professor Peter Davies has been unraveling the mystery of why some organisms including insects and fish don't freeze in the winter. His research into insect antifreeze protein ...
Scientists propose creating Maxwell's demon with two quantum dots
(Phys.org)—When you open your door on a cold winter day, the warm air from your home and the cold air from outside begin to mix and evolve toward thermal equilibrium, a state of complete entropy where the ...
Microfluidic devices move from application to fundamental science
(Phys.org) —Just a few drops of liquid or a bit more is run past specialized sensors in microfluidic devices to detect chemicals of concern to doctors and security personnel. However, these devices are ...
Electronics like it cold, and 30 K cryocooler delivers
(Phys.org)—For many electronic devices, colder is better. At low temperatures, electronic devices such as sensors and detectors operate with a higher efficiency and better overall performance than they ...
Adult cells transformed into early-stage nerve cells, bypassing the pluripotent stem cell stage
A University of Wisconsin-Madison research group has converted skin cells from people and monkeys into a cell that can form a wide variety of nervous-system cells—without passing through the do-it-all stage called the induced ...
Conversion from bad fat to good fat
Scientists from ETH Zurich in Switzerland have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other. Their work, using mice as a model organism, provides ...
Galaxies without stars: The problem of the missing hydrogen in the early Universe
(Phys.org)—Hydrogen is the most common element in the Universe, making up 75% of all normal matter and the content of stars. Although stars themselves are hot, they can only form out of the coldest gas ...
Researchers find water doped graphite flakes exhibit superconductive properties at high temperature
(Phys.org)—Researchers from the University of Leipzig have found that doping very small flakes of graphite with water, then allowing it to dry, results in a material that behaves very much like a superconductor. ...
Breaking the final barrier: Room-temperature electrically powered nanolasers
(Phys.org) —A breakthrough in nanolaser technology has been made by Arizona State University researchers.
New experiment corrects prediction in quantum theory
An international team of scientists is rewriting a page from the quantum physics rulebook using a University of Florida laboratory once dubbed the coldest spot in the universe.
Material turns 'schizophrenic' on way to superconductivity
(Phys.org) —Rice University physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a material that becomes "schizophrenic"—simultaneously ...
Chemists create nanotube structures that can expand and contract without breaking down
(Phys.org)—A group of chemists from China, Japan and Korea have succeeded in creating nanotubes that can be made to expand and contract in response to warm or cold water. Led by Myongsoo Lee of Seoul University, ...
