CRISPR just proved genes can self-heal in space for the first time ever
Posted by Kelvin Dafiaghor in category: biotech/medical
If in space, no one can hear you scream, then what happens when DNA silently breaks in microgravity? Spoiler alert: it heals itself.
This is what a CRISPR experiment that won the Genes in Space 6 contest — SYFY WIRE was at the recent launch of the Genes in Space 8 experiment to the ISS — found out. DNA damage or breakage can mean the potential for degenerative diseases such as cancer, but the fact that it can also self-repair (and in microgravity!) has enormous implications for medical treatments above and below Earth’s atmosphere.

People Look Alike if We Think They Have Similar Personalities
Posted by Jason Blain in category: neuroscience
The authors add that the research informs fundamental scientific understanding of how face recognition works in the brain, suggesting that not only a face’s visual cues but also prior social knowledge plays an active role in perceiving faces.
Summary: Knowledge of an individual’s personality can influence the perception of a face’s identity and bias it toward unrelated people or identities, researchers report.

Ancient woman’s DNA challenges scientists’ long-held theories about early humans
Posted by Genevieve Klien in category: biotech/medical
Archaeologists have analysed DNA found in the remains of a woman who died 7,200 years ago in Indonesia — challenging previous theories around the migration of early humans.
The remains of the teenager, nicknamed Besse, were discovered in the Leang Panninge cave on Sulawesi in 2015.
It is believed to be the first time ancient human DNA has been discovered in Wallacea, a group of islands between mainland Asia and Australia.

Strange brown dwarf ‘The Accident’ hints at possible treasure trove of cosmic anomalies
Posted by Genevieve Klien in category: space
A brown dwarf discovered “accidentally” by a citizen scientist appears to be somewhat of an anomaly, suggesting there might be even more lurking in our galaxy than scientists previously thought.

New Molecular Computing Device Has Unprecedented Reconfigurability Reminiscent of Brain Plasticity
Posted by Genevieve Klien in categories: computing, neuroscience
In a discovery published in the journal Nature, an international team of researchers has described a novel molecular device with exceptional computing prowess.
Reminiscent of the plasticity of connections in the human brain, the device can be reconfigured on the fly for different computational tasks by simply changing applied voltages. Furthermore, like nerve cells can store memories, the same device can also retain information for future retrieval and processing.
“The brain has the remarkable ability to change its wiring around by making and breaking connections between nerve cells. Achieving something comparable in a physical system has been extremely challenging,” said Dr. R. Stanley Williams, professor in the Department of Electrical and Computer Engineering at Texas A&M University. “We have now created a molecular device with dramatic reconfigurability, which is achieved not by changing physical connections like in the brain, but by reprogramming its logic.”

China shows off its Mars cruise drone prototype
Posted by Chima Wisdom in categories: drones, robotics/AI, solar power, space, surveillance, sustainability
China has shown off the prototype of its “Mars cruise drone” designed for surveillance work on future Mars missions, following the historic landing of a robotic rover on the Red Planet a few months ago.
The prototype of the miniature helicopter successfully passed the final acceptance, China’s National Space Science Center (CNNSC) announced on Wednesday. In the images shared by the science center, the prototype looks similar in appearance to NASA’s Ingenuity helicopter, developed for its Perseverance mission this year.
The Chinese prototype sports two rotor blades, a sensor-and-camera base, and four thin legs, but there is no solar panel at the top like Ingenuity.

Two senior FDA vaccine leaders step down as agency faces decision on boosters
Posted by Omuterema Akhahenda in categories: biotech/medical, health
Two senior leaders in the US Food and Drug Administration’s vaccine review office are stepping down, even as the agency works toward high-profile decisions around Covid-19 vaccine approvals, authorizations for younger children and booster shots.
The retirements of Dr. Marion Gruber, director of the Office of Vaccines Research and Review at FDA’s Center for Biologics Evaluation and Research, and Dr. Philip Krause, deputy director of the office, were announced in an internal agency email sent on Tuesday and shared with CNN by the FDA.
In the email, CBER Director Dr. Peter Marks said Gruber will retire on October 31 and Krause is leaving in November. Marks thanked Gruber for her leadership throughout efforts to authorize and approve Covid-19 vaccines, and Krause for serving in a “key role in our interactions to address critical vaccine-related issues with our public health counterparts around the world.”

Does E5 Reverse Aging? | Dr. Harold Katcher interview (August 2021)
Posted by Montie Adkins in categories: biotech/medical, bitcoin, cryptocurrencies, life extension
Brent Nally interviews Dr Katcher about E5 plasma filtering. “What’s the purpose of anything if you’re gonna die?” E5 human trials perhaps by the end of 2022. All treated rats so far are still alive. “The question is how many times can we do this?” So far with rats it’s 3 times. He has not given out the specific E5 formula. Right now there is another party attempting to repeat his rat experiments.
Harold earned his PhD in Biology, is Chief Science Officer of Yuvan Research and is one of the discoverers of the breast cancer gene (BRCA1). Harold describes in his book, The Illusion of Knowledge, his personal story and journey developing E5 which may be extremely promising for the field of rejuvenation/biological age reversal. Read this May2020paper.
