Lutetium-149 undergoes a rare type of radioactive decay.
A newly created isotope of the silvery metal lutetium has a strange squashed nucleus and a half-life of just a few hundred nanoseconds.
Neuroscientists from St. Petersburg University, led by Professor Allan V. Kalueff, in collaboration with an international team of IT specialists, have become the first in the world to apply the artificial intelligence (AI) algorithms to phenotype zebrafish psychoactive drug responses. They managed to train AI to determine—by fish response—which psychotropic agents were used in the experiment.
The research findings are published in the journal Progress in Neuro-Psychopharmacology and Biological Psychiatry.
The zebrafish (Danio rerio) is a freshwater bony fish that is presently the second-most (after mice) used model organism in biomedical research. The advantages for utilizing zebrafish as a model biological system are numerous, including low maintenance costs and high genetic and physiological similarity to humans. Zebrafish share 70% of genes with us. Furthermore, the simplicity of the zebrafish nervous system enables researchers to achieve more explicit and accurate results, as compared to studies with more complex organisms.
A new study, led by researchers from the University of California, Irvine, identifies a reason for why older adults are significantly more susceptible.

“Working memory” is a critical cognitive process.
The “secret code” the brain uses to create a key type of memory has finally been cracked.
This type of memory, called working memory, is what allows people to temporarily hold on to and manipulate information for short periods of time. You use working memory, for example, when you look up a phone number and then briefly remember the sequence of digits in order to dial, or when you ask a friend for directions to a restaurant and then keep track of the turns as you drive there.
The future of solar has just got brighter with this ‘ultra-thin’ device for converting stored energy into electricity.
In a remarkable development, the National Aeronautics and Space Administration (NASA) ‘holoported’ the first human being into space late last year. Holoportation is the process through which a three dimensional holographic representation of an individual is created, in a combination of a ‘hologram’ and ‘teleportation’. NASA revealed the development late last week, as it announced that it had transported flight surgeon Dr. Josef Schmid, mixed and virtual reality firm AEXA Aerospance’s chief executive officer Dr. Fernando De La Pena Llaca and others to the International Space Station (ISS) during October 2021 while the ISS was orbiting the Earth at an altitude of 250 miles above the Earth’s surface.

The event place last year when NASA’s Crew 2 astronauts were present on the ISS. The astronauts took to the skies in April last year and returned in November, soon after Dr. Schmid and others were holoportated to the orbiting space laboratory.

For World Quantum Day, the Google Quantum AI team is introducing people to the world of quantum computing by teaming up with Doublespeak Games to make The Qubit Game, a journey into quantum computing.
The JWST has been gradually cooling down ever since its successful, but the telescope took a major step forward on that front when it its massive 70-foot sunshield at the start of the year. That component allowed JWST’s systems, including its critical Mid-Infrared Instrument (MIRI), to drop to a temperature of approximately minus 298 degrees Fahrenheit (or about minus 183 degrees Celsius).
Getting the JWST to its final operating temperature required NASA and the European Space Agency to activate the telescope’s electric “cryocooler.” That in itself involved passing a technical hurdle dubbed the “pinch point,” or the stage at which the James Webb’s instruments went from minus 433 degrees Fahrenheit to minus 448 Fahrenheit.
“The MIRI cooler team has poured a lot of hard work into developing the procedure for the pinch point,” said Analyn Schneider, MIRI project manager for NASA’s Jet Propulsion Laboratory. “The team was both excited and nervous going into the critical activity. In the end, it was a textbook execution of the procedure, and the cooler performance is even better than expected.”
