Tesla releases new vision-based auto parking system

Posted by in categories: robotics/AI, transportation

Tesla has started to release a new version of its auto parking system, an updated automated parking for its newer vision-only vehicles.

Ever since Tesla stopped using ultrasonic sensors in its new vehicles and only relied on cameras for its ADAS features, its vehicles have lacked auto-parking features.

That move started in 2022.

Condor Telescope reveals a New World for Astrophysicists

Posted by in categories: computing, education, physics, space

A new telescope called the “Condor Array Telescope” may open up a new world of the very-low-brightness universe for astrophysicists. Four new papers, published back to back in the Monthly Notices of the Royal Astronomical Society (MNRAS) this month, present the first scientific findings based on observations acquired by Condor. The project is a collaborative led by scientists in the Department of Physics and Astronomy at Stony Brook University and the American Museum of Natural History (AMNH).

According to lead researchers Kenneth M. Lanzetta, Ph.D., a Professor in the Department of Physics and Astronomy and Stefan Gromoll of Stony Brook, and Michael M. Shara, Ph.D., Curator in the Department of Astrophysics at the AMNH, Condor is now in full operation. The new “array telescope” uses computers to combine light from several smaller telescopes into the equivalent of one larger telescope and is able to detect and study astronomical features that are too faint to be seen with conventional telescopes.

In the first paper, Lanzetta and colleagues used Condor to study extremely faint “stellar streams” surrounding the nearby galaxy NGC 5,907, a well-known spiral galaxy located some 50 million light years from Earth.

Batteries for Airborne Electric Vehicles that Take Off and Land Vertically

Posted by in categories: drones, sustainability

EVTOL battery analysis reveals unique operating demands. Researchers at the Department of Energy’s Oak Ridge National Laboratory are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically.

These aircraft, commonly called eVTOLs, range from delivery drones to urban air taxis. They are designed to rise into the air like a helicopter and fly using wing-borne lift like an airplane. Compared with helicopters, eVTOLs generally use more rotors spinning at a lower speed, making them both safer and quieter.

The airborne EV’s aren’t just flying cars, and ORNL researchers conclude that eVTOL batteries can’t just be adapted from electric car batteries. So far that has been the dominant approach to the technology, which is mostly in the modeling stage. ORNL researchers took a different tack by evaluating how lithium-ion batteries fare under extremely high power draw.

Tryptophan in Diet and Gut Bacteria Protect against E. Coli Infection, study shows

Posted by in categories: biotech/medical, neuroscience

Gut bacteria and a diet rich in the amino acid tryptophan can play a protective role against pathogenic E. coli, which can cause severe stomach upset, cramps, fever, intestinal bleeding and renal failure, according to a study published March 13 in Nature.

The research reveals how dietary tryptophan—an amino acid found mostly in animal products, nuts, seeds, whole grains and legumes—can be broken down by gut bacteria into small molecules called metabolites. It turns out a few of these metabolites can bind to a receptor on gut epithelial (surface) cells, triggering a pathway that ultimately reduces the production of proteins that E. coli use to attach to the gut lining where they cause infection. When E. coli fail to attach and colonize the gut, the pathogen benignly moves through and passes out of the body.

The research describes a previously unknown role in the gut for a receptor, DRD2 has otherwise been known as a dopamine (neurotransmitter) receptor in the central and peripheral nervous systems.

In this video I explain how Bohmian mechanics, also known as the Pilot Wave Interpretation of Quantum Mechanics works, and what is good and bad about it. I also tell you a little about the history of the subject because I think it is helpful to understand the situation in which the subject is today.

Nvidia and Cerebras highlight the crazy acceleration in processing power

Posted by in categories: robotics/AI, space, supercomputing

Coming hot on the heels of two massive announcements last year, last week Nvidia and Cerebras showed yet again that the pace of computing is still accelerating.

The first CS-2 based Condor Galaxy AI supercomputers went online in late 2023, and already Cerebras is unveiling its successor the CS-3, based on the newly launched Wafer Scale Engine 3, an update to the WSE-2 using 5nm fabrication and boasting a staggering 900,000 AI optimized cores with sparse compute support. CS-3 incorporates Qualcomm AI 100 Ultra processors to speed up inference.

Bank of America ignored text but answered call — then she lost $18k via Zelle

Posted by in category: futurism

A BANK of America customer was deprived of $18,000 after she answered a call she thought was from the company.

Lura Ball, of California, said she normally ignores strange texts or calls after being scammed.

She lost thousands after being ordered to use the platform, Zelle, as reported by the ABC affiliate KABC.
