'Deepfaking the mind' could improve brain-computer interfaces for people with disabilities

Posted: 18 Nov 2021 05:36 PM PST

Researchers are using generative adversarial networks (GANs) -- technology best known for creating deepfake videos and photorealistic human faces -- to improve brain-computer interfaces for people with disabilities. The team successfully taught an AI to generate synthetic brain activity data. The data, specifically neural signals called spike trains, can be fed into machine-learning algorithms to improve the usability of brain-computer interfaces (BCI).

Warning over antibiotic-resistant bacteria

Significant levels of antibiotic-resistant bacteria have been found at locations in and around Cambridge, England. The researchers found potentially dangerous Pseudomonas bacteria in over a fifth of samples collected close to the River Cam.

Study challenges standard ideas about piezoelectricity in ferroelectric crystals

Posted: 17 Nov 2021 06:15 PM PST

For years, researchers believed that the smaller the domain size in a ferroelectric crystal, the greater the piezoelectric properties of the material. However, recent findings have raised questions about this standard rule.

Alien organisms – hitchhikers of the galaxy?

Chemistry researchers have developed a new method using blue light to create pharmaceuticals in a more sustainable way, significantly reducing the amount of energy needed and the chemical waste created in the manufacture process.

Advanced microscopes help scientists understand how cells break down proteins

Posted: 17 Nov 2021 08:51 AM PST

Researchers have used advanced electron microscopes to delve deeper into the process of protein degradation. They described the structure of a key enzyme that helps mediate ubiquitination in yeast, part of a cellular process called the N-degron pathway that may be responsible for determining the rate of degradation for up to 80% of equivalent proteins in humans.

How herpes checks into the nervous system for life

Posted: 17 Nov 2021 08:51 AM PST

More than half of U.S. adults are carriers of HSV1 (herpes simplex virus type 1) which hibernates in the peripheral nervous system and can never be eradicated. A new study has uncovered herpes' sneaky strategy for infecting the nervous system, opening a door to long-needed vaccine development for both HSV1 and its close sibling HSV2.

Unvaccinated: The kids aren’t alright

Posted: 16 Nov 2021 05:15 PM PST

Close to 10 million children in lower-income countries have never been vaccinated against any infectious disease. These 'zero-dose' kids hold a lesson for all of us, says a public-health expert.

How grandmothers' brains react to the sight of their grandchildren
