Largest brain study of 62,454 scans identifies drivers of brain aging

In the largest known brain imaging study, scientists from Amen Clinics (Costa Mesa, CA), Google, John’s Hopkins University, University of California, Los Angeles and the University of California, San Francisco evaluated 62,454 brain SPECT (single photon emission computed tomography) scans of more than 30,000 individuals from 9 months old to ...

Southern California coast emerges as a toxic algae hot spot

A new, comprehensive survey led by USC scientists shows the Southern California coast harbors some of the world’s highest concentrations of an algal toxin dangerous to wildlife and people who eat local seafood. Episodic outbreaks of algae-produced toxins make headlines every few years when stricken marine animals wash ashore between ... Read More »

Bigger proteins, stronger threads: Synthetic spider silk

Spider silk is among the strongest and toughest materials in the natural world, as strong as some steel alloys with a toughness even greater than bulletproof Kevlar. Spider silk’s unmatched combination of strength and toughness have made this protein-based material desirable for many applications ranging from super thin surgical sutures ... Read More »

Quantum leap for Einstein’s scientific principle

How Einstein’s equivalence principle extends to the quantum world has been puzzling physicists for decades, but a team including a University of Queensland researcher has found the key to this question. UQ physicist, Dr Magdalena Zych from the ARC Centre of Excellence for Engineered Quantum Systems, and the University of ... Read More »

Making light work of quantum computing

Light may be the missing ingredient in making usable quantum silicon computer chips, according to an international study featuring a University of Queensland researcher. The team has engineered a silicon chip that can guide single particles of light — photons — along optical tracks, encoding and processing quantum-bits of information ... Read More »

Ice confirmed at the moon’s poles

In the darkest and coldest parts of its polar regions, a team of scientists has directly observed definitive evidence of water ice on the Moon’s surface. These ice deposits are patchily distributed and could possibly be ancient. At the southern pole, most of the ice is concentrated at lunar craters, ... Read More »

Light from ancient quasars helps confirm quantum entanglement

Last year, physicists at MIT, the University of Vienna, and elsewhere provided strong support for quantum entanglement, the seemingly far-out idea that two particles, no matter how distant from each other in space and time, can be inextricably linked, in a way that defies the rules of classical physics. Take, ... Read More »

A new generation of artificial retinas based on 2D materials

Scientists report they have successfully developed and tested the world’s first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible device, based on very thin 2D materials, could someday restore sight to the millions of people with retinal diseases. And with a ... Read More »

A GPS for inside your body

Medical processes like imaging often require cutting someone open or making them swallow huge tubes with cameras on them. But what if could get the same results with methods that are less expensive, invasive and time-consuming? Researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) led by professor Dina ... Read More »

A paper battery powered by bacteria

In remote areas of the world or in regions with limited resources, everyday items like electrical outlets and batteries are luxuries. Health care workers in these areas often lack electricity to power diagnostic devices, and commercial batteries may be unavailable or too expensive. New power sources are needed that are ...

Astronomers observe cosmic steam jets and molecules galore

The ALMA telescope in Chile has transformed how we see the universe, showing us otherwise invisible parts of the cosmos. This array of incredibly precise antennas studies a comparatively high-frequency sliver of radio light: waves that range from a few tenths of a millimeter to several millimeters in length. Recently, ... Read More »

Ants, acorns and climate change

The relatively swift adaptability of tiny, acorn-dwelling ants to warmer environments could help scientists predict how other species might evolve in the crucible of global climate change. That’s a big-picture conclusion from research into the some of the world’s smallest creatures, according to evolutionary biologists at Case Western Reserve University. ... Read More »

Moderate carbohydrate intake may be best for health, study suggests

Eating carbohydrates in moderation seems to be optimal for health and longevity, suggests new research published in The Lancet Public Health journal. The observational study of more than 15,400 people from the Atherosclerosis Risk in Communities Study (ARIC) in the USA found that diets both low (< 40% energy) and ... Read More »

Astronomers identify some of the oldest galaxies in the universe

Astronomers from the Institute for Computational Cosmology at Durham University and the Harvard-Smithsonian Center for Astrophysics, have found evidence that the faintest satellite galaxies orbiting our own Milky Way galaxy are amongst the very first galaxies that formed in our Universe. Scientists working on this research have described the finding ... Read More »

Novel sensors could enable smarter textiles

A team of engineers at the University of Delaware is developing next-generation smart textiles by creating flexible carbon nanotube composite coatings on a wide range of fibers, including cotton, nylon and wool. Their discovery is reported in the journal ACS Sensors where they demonstrate the ability to measure an exceptionally ... Read More »
