Low-tech secret handshake box tests 99.9% effective against car theft

Posted by in categories: security, transportation

With US car thefts up 25.1% since 2019, it’s clear that high-tech key fob immobilizers aren’t cutting the mustard. But this might: UMich researchers have created a charmingly low-tech anti-theft device that turns the whole car into a security keypad.

Keyless entry and ignition are a brilliant step up in convenience from the old “stick key in hole and turn” method of starting cars, but thieves and hackers with a bit of know-how and some specialist gear are finding late-model keyless cars quick and easy to break into and steal. Between this kind of thing and Tik Tok car theft challenges, criminals are having a field day in the post-COVID era.

A team at the University of Michigan has come up with a fun solution that doesn’t use wireless signals at all. The “Battery Sleuth,” as they’ve called it, sits between the car’s battery and its electrical system, and measures fluctuations in voltage, looking for a specific set of voltage changes that act as a secret handshake of sorts between driver and car. Only when this handshake is complete will the device let the full power of the battery through to fire up the starter motor.

Researchers grow precise arrays of nanoLEDs

Posted by in categories: computing, nanotechnology, solar power, sustainability

Halide perovskites are a family of materials that have attracted attention for their superior optoelectronic properties and potential applications in devices such as high-performance solar cells, light-emitting diodes, and lasers.

A new MIT platform enables researchers to “grow” halide perovskite nanocrystals with precise control over the location and size of each individual crystal, integrating them into nanoscale light-emitting diodes. Pictured is a rendering of a nanocrystal array emitting light.

5 SLE Patients See Disease Remission With CAR T-cell Therapy

Posted by in category: biotech/medical

A CAR T-cell therapy targeting disease-driving immune cells safely led to sustained disease remission for five people with systemic lupus erythematosus (SLE) who’d previously failed to respond to other treatments, a recent study reported.

Treatment was also highly specific, preventing autoimmune activity, but didn’t impair general immune system function.

“These data provide new therapeutic possibilities to control SLE disease activity,” the researchers wrote. “Longer follow-ups in larger cohorts of patients will be necessary to confirm sustained absence of autoimmunity and resolution of inflammation in patients with SLE who have received CAR T cell therapy.”

Vaccine delivers a boost to T cell therapy

Posted by in categories: biotech/medical, engineering

Engineering T cells to destroy cancer cells has shown success in treating some types of cancer, such as leukemia and lymphoma. However, it hasn’t worked as well for solid tumors.

One reason for this lack of success is that the T cells target only one antigen (a target protein found on the tumors); if some of the tumor cells don’t express that antigen, they can escape the T cell attack.

MIT researchers have now found a way to overcome that obstacle, using a vaccine that boosts the response of engineered T cells, known as chimeric antigen receptor (CAR) T cells, and also helps the immune system generate new T cells that target other tumor antigens. In studies in mice, the researchers found that this approach made it much more likely that tumors could be eradicated.

Relationship among bats, parasitic bat flies, and associated pathogens in Korea

Posted by in categories: biotech/medical, health

Conclusions.

The vectorial role of bat flies should be checked by testing the same pathogen and bacterial organisms by collecting blood from host bats. This study is of great interest in the fields of disease ecology and public health owing to the bats’ potential to transmit pathogens to humans and/or livestock.

Covid is a bat bourne disease from such zoonotic transmission.

Observations made by NASA

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.” NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

Scientists Find the Source of a Mysterious Brain Wave That Could Boost Memory and Creativity

Posted by in categories: biotech/medical, neuroscience

In a way, the brain changes its channels as we go about our day to match our internal state of mind to outside requirements—though at any point, the channels can bleed over.

But there’s a mysterious outcast: a frequency called theta waves. They happen while we’re awake or asleep. For decades, these waves have taunted neuroscientists trying to decipher their functions. Theta waves seem to help mice navigate mazes, but also support memory in humans.

It’s not just academic curiosity. Our ability to navigate complex new environments and keep those memories declines with age. It’s especially tough for people with Alzheimer’s disease. By finding the driving source of theta waves, we could potentially enhance them—using neurostimulation or other methods—to slow cognitive decline.

The Philosophy of Artificial Intelligence

Posted by in categories: innovation, robotics/AI

From Hollywood, to technological innovation, A.I. has been baked into the sociological subconscious for decades. With a new contemporary push, artificial intelligence is capturing the human imagination and pushing it to new depths. We’re hoping to explore all those weird intricacies here.

Big thanks to @ThenNow for lending his voice on the quote within “The Psychoanalysis of Artificial Intelligence”. I’m sure you’re more than ahead of me, but do go check him out!
