Shrinking massive neural networks used to model language

Deep learning neural networks can be massive, demanding major computing power. In a test of the 'lottery ticket hypothesis,' researchers have found leaner, more efficient subnetworks hidden within BERT models. The discovery could make natural language processing more accessible.

Researchers study influence of cultural factors on gesture design

Freehand gesture-based interfaces in interactive systems are becoming more common, but what if your preferred way to gesture a command - say, changing the TV to channel 10 - significantly differed from that of a user from another culture? Would the system recognize your command? Researchers explored this question and found that some gesture choices are significantly influenced by the cultural...

Why long-suffering hosts grow a thick skin

Occasionally, following a transplant procedure, the donor's immune cells recognize the recipient's tissues as foreign and trigger a multisystem disorder called graft-versus-host disease (GVHD). Occurring commonly after bone marrow or stem cell transplants performed to treat some blood cancers, GVHD may even follow solid organ transplants and is, in essence, the reverse of transplant rejection....

Tweaking carotenoid genes helps tomatoes bring their A-game

Researchers led by the University of Tsukuba demonstrated that Target-AID gene editing technology can be used to simultaneously introduce single-base changes into multiple genes in tomatoes. Using this technique, the researchers altered three genes associated with carotenoid accumulation, resulting in elevated levels of carotenoids, particularly lycopene, in the resulting tomato lines. This...

Next step in simulating the universe

Researchers have developed a way to accurately represent the behavior of elementary particles called neutrinos in computer simulations of the Universe. The simulation results reveal the effects of neutrinos on the formation and growth of galaxies for different values of the uncertain neutrino mass. The work marks a milestone in simulating the Universe and could help determine the neutrino mass.

Drug reverses age-related mental decline within days, mouse study shows

Just a few doses of an experimental drug can reverse age-related declines in memory and mental flexibility in mice, according to a new study. The drug, called ISRIB, has already been shown in laboratory studies to restore memory function months after traumatic brain injury (TBI), reverse cognitive impairments in Down Syndrome, prevent noise-related hearing loss, fight certain types of prostate...

Researchers develop customized targeting of bacteria using lysins

Researchers have developed a method to produce engineered lysins that can be used to selectively kill bacteria of interest while leaving others unharmed. The discovery presents a promising alternative to antibiotics for treating existing drug-resistant bacteria without the risk of causing resistance.
