Biomedical engineers find neural activity during rest is highly organized
2021-11-28 17:09 UNIVERSITY PARK, Pa. — When mice rest, individual neurons fire in seconds-long, coordinated cascades, triggering activity across the brain, according to research from Penn State and the National Institutes of Health. Previously, this was thought to be a relatively random process — single neurons firing spontaneously at random times without external stimulations. The finding, published Nov. 18 i...
193 countries adopt first-ever global agreement on the Ethics of Artificial Intelligence
2021-11-27 19:59 All the Member states of the UN Educational, Scientific and Cultural Organization (UNESCO) adopted on Thursday a historic agreement that defines the common values and principles needed to ensure the healthy development of AI. Artificial intelligence is present in everyday life, from booking flights and applying for loans to steering driverless cars. It is also used in specialized fields such as cancer scre...
Biologists have found an unexpected similarity between carrion bees, hyenas and vultures
2021-11-26 16:28 Bees include representatives of seven families and thousands of species of insects. The vast majority of them are vegetarians, although they can eat animal food from time to time. Only individual bees are scavengers "by nature" and do not collect pollen at all. These include, for example, trigons (Trigona), which live in South and Central America and flock in masses to the corpses of animals, quic...
MSU physicists have proposed a method for restoring the energy of an electron beam to measure neutrino oscillations
2021-11-25 18:20 Employees of the D.V. Skobeltsyn (SINP) and the Faculty of Physics of Moscow State University, together with foreign colleagues, proposed ways to improve the existing models of neutrino-nuclear interaction by electron scattering methods, which made it possible to test different versions of such models. Neutrino experiments make it possible to study one of the most interesting physical phenomena - neutrino ...
Ultrashort laser pulses destroy superbugs without damaging human cells
2021-11-24 18:12 Antibiotics were one of the most important inventions of the 20th century, but their effectiveness drops dramatically as bacteria develop resistance to them. Now researchers from the University of St. Louis have shown that ultra-short pulses of laser light can kill bacteria and viruses without damaging human cells.The rise in multidrug-resistant "superbugs" is a looming health crisis that, according to some...
DNA replication under the microscope
2021-11-23 18:05 Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged.  Cellular DNA is continuously exposed to both endogenous and exogenous DNA-damaging agents, such as reactive oxygen species and UV radiation. To reduce the biological consequences of DNA damage, all living organisms have evolved mechanisms to tolerate and ...
Youth embody ‘spirit’ of 21st century more than parents, new survey shows
2021-11-22 17:51 Even in the face of the COVID-19 pandemic, climate change and other global challenges, children and youth are nearly 50 per cent more likely than older people to believe that the world is becoming a better place, according to the results of a landmark intergenerational poll published on Thursday.  The international survey was conducted by the UN Children’s Fund (UNICEF) and Gallup, the global an...
