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.
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 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 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.”
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.

ET could harvest energy from a black hole.
Researchers show how intelligent aliens might draw nearly-limitless power from a black hole using a Dyson sphere.
Circa 2019
An international team of physicists have created what they’re calling the world’s smallest engine. How small is it? The entire engine is a single calcium ion, making it around 10 billion times smaller than a car engine.
The experimental engine was conceived by an international team led by Professor Ferdinand Schmidt-Kaler and Ulrich Poschinger of Johannes Gutenberg University in Mainz, Germany. The engine is electrically charged, which makes it easy to trap using electric fields. The moving parts of the engine are the ion’s “intrinsic spin.” On an atomic level, spin is a measurement of an atom’s angular momentum.
Within the engine, spin is used to capture and convert heat absorbed from laser beams into oscillations, or vibrations, of the trapped ion. The vibrations act as a flywheel and its energy is placed into units called “quanta,” predicted by quantum mechanics.
Lotus targets almost2000horsepower for its new hypercar.
Lotus is wary of corporate hubris these days, preferring to remain quiet when previously it would have shouted. Former boss Dany Bahar once introduced five sports-car concepts on the same auto-show stand, none of which made it even close to production. Lotus’s resources have grown massively since the thinly applied gild of the Bahar era; Chinese automaker Geely took a majority stake in the British sports-car maker two years ago. But although the company has recruited hundreds of new engineers, and is known to be working on several new models, few details have been shared so far.
An Australian company by the name of HyperPower Technologies has developed an electric motor that generates a mammoth 1,340 horsepower.
The electric motor, code-named the QFM-360-X, measures about 17 inches in diameter and is designed to be scalable. HyperPower said ten of them could be mounted on a common shaft to deliver 13,400 hp.
To demonstrate the performance, HyperPower teamed up with electric drag racers Top EV Racing and built a Top Fuel-style dragster powered by four of the motors for a combined output of 5,360 hp. Performance estimates for the electric beast include a 0–124 mph time of 0.8 seconds, a 0–330 mph time of 3.7 seconds, and a top speed of 380 mph.
