Surprising Brain Area Linked to Short-Term Memory

Posted by in categories: biotech/medical, genetics, neuroscience

Researchers at Rockefeller University have just released findings from a new study, done in mice, which identifies a gene that is critical for short-term memory but functions in a part of the brain not traditionally associated with memory. Classical models for short-term memory typically assume that all neuronal activity is contained within the prefrontal cortex (PFC), yet, data from this new study suggests that a G-protein coupled receptor in the thalamus may play a large role. Data from the study was published recently in Cell through an article titled “A Thalamic Orphan Receptor Drives Variability in Short Term Memory.”

Interestingly, in order to discover new genes and brain circuits that are important for short-term memory, the researchers turned to studying genetically diverse mice, rather than inbred mice commonly used in research.

“We needed a population that is diverse enough to be able to answer the question of what genetic differences might account for variation in short-term memory,” explained co-senior study investigator Praveen Sethupathy, PhD, an associate professor of biomedical sciences in Cornell’s College of Veterinary Medicine and director of the Cornell Center for Vertebrate Genomics.

Could a poo transplant one day be the secret of eternal youth?

Posted by in categories: biotech/medical, life extension, neuroscience

Fecal transplants could one day be used as a therapy to restore cognitive function in the elderly—according to new research from the University of East Anglia, the University of Florence and the Quadram Institute.

A new study published today shows how fecal transplants from older to younger mice altered their , which in turn impacted their spatial learning and memory.

Neanderthal genes may be to blame in some severe coronavirus cases

Posted by in categories: biotech/medical, genetics

Genes inherited from Neanderthal ancestors may be involved in some cases of severe Covid-19 disease, researchers in Germany reported Wednesday.

A team of experts on Neanderthal genetics examined a strand of DNA that has been associated with some of the more serious cases of Covid-19 and compared it to sequences known to have been passed down to living Europeans and Asians from Neanderthal ancestors.

The DNA strand is found on chromosome 3, and a team of researchers in Europe has linked certain variations in this sequence with the risk of being more severely ill with Covid-19.

Potty training: NASA tests new $23M titanium space toilet

Posted by in category: space

CAPE CANAVERAL, Fla. (AP) — NASA’s first new space potty in decades — a $23 million titanium toilet better suited for women — is getting a not-so-dry run at the International Space Station before eventually flying to the moon.

It’s packed inside a cargo ship that should have blasted off late Thursday from Wallops Island, Virginia. But the launch was aborted with just two minutes remaining in the countdown. Northrop Grumman said it would try again Friday night if engineers can figure out what went wrong.

Barely 100 pounds (45 kilograms) and just 28 inches (71 centimeters) tall, the new toilet is roughly half as big as the two Russian-built ones at the space station. It’s more camper-size to fit into the NASA Orion capsules that will carry astronauts to the moon in a few years.

Tunable free-electron X-ray radiation from van der Waals materials

Posted by in categories: biotech/medical, chemistry, engineering, nanotechnology, quantum physics, security

Technion researchers have developed accurate radiation sources that are expected to lead to breakthroughs in medical imaging and other areas. They have developed precise radiation sources that may replace the expensive and cumbersome facilities currently used for such tasks. The suggested apparatus produces controlled radiation with a narrow spectrum that can be tuned with high resolution, at a relatively low energy investment. The findings are likely to lead to breakthroughs in a variety of fields, including the analysis of chemicals and biological materials, medical imaging, X-ray equipment for security screening, and other uses of accurate X-ray sources.

Published in the journal Nature Photonics, the study was led by Professor Ido Kaminer and his master’s student Michael Shentcis as part of a collaboration with several research institutes at the Technion: the Andrew and Erna Viterbi Faculty of Electrical Engineering, the Solid State Institute, the Russell Berrie Nanotechnology Institute (RBNI), and the Helen Diller Center for Quantum Science, Matter and Engineering.

The researchers’ paper shows an experimental observation that provides the first proof-of-concept for theoretical models developed over the last decade in a series of constitutive articles. The first article on the subject also appeared in Nature Photonics. Written by Prof. Kaminer during his postdoc at MIT, under the supervision of Prof. Marin Soljacic and Prof. John Joannopoulos, that paper presented theoretically how two-dimensional materials can create X-rays. According to Prof. Kaminer, “that article marked the beginning of a journey towards sources based on the unique physics of two-dimensional materials and their various combinations—heterostructures. We have built on the theoretical breakthrough from that article to develop a series of follow-up articles, and now, we are excited to announce the first experimental observation on the creation of X-ray radiation from such materials, while precisely controlling the radiation parameters.”
