A research team led by Cardiff University scientists say they are closer to understanding how a supermassive black hole (SMBH) is born thanks to a new technique that has enabled them to zoom in on one of these enigmatic cosmic objects in unprecedented detail.

Astronomers zoom in on black hole with one of the lowest masses ever observed in nearby. A research team led by Cardiff University scientists say they are closer to understanding how a supermassive black hole (SMBH) is born thanks to a new technique that has enabled them to zoom in on one of these enigmatic cosmic objects in unprecedented detail.

Scientists are unsure as to whether SMBHs were formed in the extreme conditions shortly after the big bang, in a process dubbed a ‘direct collapse’, or were grown much later from ‘seed...

Scientists discover Key Element of Strong Antibody response to COVID-19

Many anti-SARS-CoV-2 antibodies are produced by a common antibody gene. X-ray crystallography revealed how specific features of these antibodies (two of which are depicted here in yellow and orange, attached to the virus) enable potent recognition of the virus’s spike protein. Graphic by Meng Yuan, Hejun Liu and Nicholas Wu in the Wilson lab.

The findings support many vaccine strategies being used to tackle the new coronavirus. A team led by scientists at Scripps Research has discovered a common molecular feature found in many of the human antibodies that neutralize SARS-CoV-2, the coronavirus that causes COVID-19.

The scientists, whose study appears July 13 in Science, reviewed data on nearly 300 anti-SARS-CoV-2 antibodies that their labs and others have found in convalescent COVID...

Artificial ‘Neurotransistor’ created

Intrinsic plasticity of silicon nanowire neurotransistors for ...
Structure and electrical characteristics of Si NW neurotransistors.

Imitating the functioning of neurons using semiconductor materials. While the optimization of conventional microelectronics is slowly reaching its physical limits, nature offers us a blueprint how information can be processed and stored efficiently: our own brain. Scientists have now successfully imitated the functioning of neurons using semiconductor materials.

Especially activities in the field of artificial intelligence, like teaching robots to walk or precise automatic image recognition, demand ever more powerful, yet at the same time more economical computer chips...
