The detective aboard NASA's Perseverance rover

Mars is a long way from 221B Baker Street, but one of fiction's best-known detectives will be represented on the Red Planet after NASA's Perseverance rover touches down on Feb. 18, 2021. SHERLOC, an instrument on the end ...

Astrophysicists capture new class of transient objects

Move aside, AT2018COW. There is a new astronomical transient in the universe, and it is faster, heavier and brighter at radio wavelengths than its mysterious predecessors.

Climate change could dramatically reduce U.S. snowstorms

A new study led by Northern Illinois University scientists suggests American winters late this century could experience significant decreases in the frequency, intensity and size of snowstorms.

Topological insulators feature lossless conduction at the edges

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...

A nice day for a quantum walk

Researchers at the Center for Quantum Information and Quantum Biology at Osaka University used trapped ions to demonstrate the spreading of vibrational quanta as part of a quantum random walk. This work relies on their exquisite ...

A method to produce hydrogen in vivo photosynthetically

Researchers have been trying to produce hydrogen photosynthetically for quite some time now, as this could pave the way toward a more sustainable energy infrastructure. Some of them have succeeded by fusing different hydrogenases ...

Even mild coronavirus illness may confer some immunity: study

Even people with minor illness from the coronavirus can develop antibodies that could leave them immunised for several weeks or more, according to an early French study that tested hospital staff with mild infections.

The first 3-D map of the heart's neurons

The normal functioning of our hearts is maintained by our body's control center—the brain—via an intricate network of nerves. When this communication is disrupted, it results in heart disease, including heart attacks, ...

Miniature rock art expands horizons

Australian archaeologists have discovered some of the most detailed examples of rare, small-scale rock art in the form of miniature stencils in a rockshelter traditionally owned by the Marra people.

Mathematicians reveal the science behind figure skating

A new mathematical model developed by University of Alberta scientists shows how figure skaters move across the ice—and could help professional skaters hone their technique or prevent injuries.

Ignorance would be bliss: the family ties that grind

The ability to recognize relatives can make life more dangerous for the female of the species, new research carried out at the University of St Andrews, the Institute for Advanced Study in Toulouse and the University of Valencia ...

Researchers capture rarely heard narwhal vocalizations

With the help of Inuit hunters, geophysicists recently recorded the various calls, buzzes, clicks and whistles of narwhals as they summered in a Greenland fjord. The recordings help scientists better understand the soundscape ...

Editing plant chromosomes using molecular scissors

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants. The research teams of Professor Holger Puchta of Karlsruhe Institute of Technology (KIT) and ...

Catch and release: Collagen-mediated control of PEDF availability

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific ...

Directed protein evolution with CRISPR-Cas9

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory. Based on this method, Max Planck researchers from Martinsried have now developed ...

Chromosomal speciation in wild house mice

Alterations to chromosomes are considered important in speciation (the process by which new species are formed). This is because several chromosomal rearrangements can make the genome of a few individuals in a population ...

Saturable plasmonic metasurfaces for laser mode locking

Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear regime, their applications ...

Metal collector made of bacteria

Bacteria, fungi and plants sometimes produce metal-binding substances that can be harnessed, for example for the extraction of raw materials, for their separation, for cleaning soils or for medical purposes.

Increased usability and precision in vascular imaging

Researchers at the University of Zurich have developed a new X-ray contrast agent. The contrast agent is easier to use and distributes into all blood vessels more reliably, increasing the precision of vascular imaging. This ...
