Phys.org / True scale of carbon impact from long-distance travel revealed
The reality of the climate impact of long-distance passenger travel has been revealed in new research from the University of Leeds.
Phys.org / Small change in Earth's oxygen levels may have sparked huge evolutionary leap
New research provides the clearest evidence yet that the Cambrian explosion—a rapid burst of evolution 540 million years ago, could have been triggered by only a small increase in oxygen levels in Earth's atmosphere and ...
Phys.org / Physicists' laser experiment excites atom's nucleus, may enable new type of atomic clock
For nearly 50 years, physicists have dreamed of the secrets they could unlock by raising the energy state of an atom's nucleus using a laser. The achievement would allow today's atomic clocks to be replaced with a nuclear ...
Phys.org / Dual-laser approach could lower cost of high-resolution 3D printing
Researchers have developed a new two-photon polymerization technique that uses two lasers to 3D print complex high-resolution structures. The advance could make this 3D printing process less expensive, helping it find wider ...
Phys.org / Novel method enhances size-controlled production of luminescent quantum dots
Luminescence refers to the result of a process in which an object absorbs light at one wavelength and then re-emits it at another wavelength. Through light absorption, electrons in the ground state of the material are excited ...
Phys.org / Scientists create world's most amazingly difficult maze with future potential to boost carbon capture
In new research, physicists have wielded the power of chess to design a group of intricate mazes, which could ultimately be used to tackle some of the world's most pressing challenges.
Phys.org / Human presence shifts balance between leopards and hyenas in East Africa
Who's stronger? A solitary leopard or cackle of hyenas? And which is best at getting along with humans?
Phys.org / Study: More complaints, worse performance when AI monitors employees
Organizations using AI to monitor employees' behavior and productivity can expect them to complain more, be less productive and want to quit more—unless the technology can be framed as supporting their development, Cornell ...
Phys.org / UV radiation damage leads to ribosome roadblocks, causing early skin cell death
In a recent study, researchers at Johns Hopkins Medicine suggest that the cell's messenger RNA (mRNA)—the major translator and regulator of genetic material—along with a critical protein called ZAK—spurs the cell's ...
Phys.org / Scientists crack new method for high-capacity, secure quantum communication
Scientists have made a significant breakthrough in creating a new method for transmitting quantum information using particles of light called qudits. These qudits promise a future quantum internet that is both secure and ...
Phys.org / New understanding of a common plant enzyme could lead to better crop management
New findings about chitinases, enzymes found naturally in plants, could allow farmers to address fungal infections sooner and more efficiently.
Phys.org / How climate change is affecting where species live
As the climate warms, many species are on the move, raising new challenges for policy-makers around the world. Shifts in the ranges of mosquitoes and disease-bearing ticks and bats are introducing illnesses such as malaria ...
