UPTON, NY-- A team of scientists from the U.S. Department of Energy's Brookhaven National Laboratory and Lawrence Berkeley National Laboratory designed, created, and successfully tested a new algorithm to make smarter scientific measurement decisions. The algorithm, a form of artificial intelligence (AI), can make autonomous decisions to define and perform the next step of an experiment.
UPTON, NY--To increase the processing speed and reduce the power consumption of electronic devices, the microelectronics industry continues to push for smaller and smaller feature sizes. Transistors in today's cell phones are typically 10 nanometers (nm) across--equivalent to about 50 silicon atoms wide--or smaller. Scaling transistors down below these dimensions with higher accuracy requires advanced materials for lithography--the primary technique for printing electrical circuit elements on silicon wafers to manufacture electronic chips.
With water scarcity a growing problem worldwide, University of California, Berkeley, researchers are close to producing a microwave-sized water harvester that will allow you to pull all the water you need directly from the air -- even in the hot, dry desert.
Crows can voluntarily control the release and onset of their calls, suggesting that songbird vocalizations are under cognitive control, according to a study published August 27 in the open-access journal PLOS Biology by Katharina Brecht of the University of Tübingen, and colleagues.
A team of Argentinian scientists from the National Council of Scientific and Technical Research (CONICET) made the discovery after studying a coprolite taken from a rock-shelter in the country's mountainous Catamarca Province, where the remains of now extinct megafauna have previously been recovered in stratigraphic excavations.
Radiocarbon dating revealed that the coprolite and thus the parasitic roundworm eggs preserved inside dated back to between 16,570 and 17,000 years ago, towards the end of the last Ice Age.
Natural Killer (NK) cells have long been the soldiers of the immune system that prevents the growth and spread of cancers, and subduing this army of cells is one of the key ways that tumours take hold.
Biocompatible gold nanoparticles designed to convert near-infrared light to heat have been shown to safely and effectively ablate low- to intermediate-grade tumors within the prostate, according to a study conducted at the Icahn School of Medicine and published in the journal Proceedings of the National Academy of Sciences. This treatment could offer patients a targeted therapy option that would preserve critical structures within the prostate, thus avoiding side effects associated with whole-gland treatment such as prostatectomies.
Newly formed Tropical Depression 6 in the Atlantic Ocean may have just formed, but it did so under adverse atmospheric conditions. The depression is battling wind shear and it's apparent on imagery from NASA's Aqua satellite.
Wind shear is a measure of how the speed and direction of winds change with altitude. When outside winds batter a tropical cyclone, it affects its circulation. A less circular storm tends to slow down in its spin and weaken.
Those who study and treat disorders of the mind - such as neuroscientists, psychiatrists and therapists - are in a position of influence. Their decisions and actions have the potential to impact individuals at the deepest levels by affecting our memories and even how we see ourselves. Such professionals "...occupy positions of intellectual authority" as neuroscientist and artist Ann E. Fink writes. Their choices can have profound consequences.
Scientists find unusual behaviors in colloidal crystals.
Atoms have a positively charged center surrounded by a cloud of negatively charged particles. This type of arrangement, it turns out, can also occur at a more macroscopic level, giving new insights into the nature of how materials form and interact.
