Submission + - This crewless ship is defending Denmark's and NATO's waters. This is how it work (euronews.com)

Submitted by alternative_right
alternative_right writes: Drones are mounted on these 10-meter-long vessels and artificial intelligence (AI) helps analyse data of the surrounding environment under and above the surface of the ocean using advanced sensors.

"So, the vehicles [work] like a truck. The truck carries the sensors and we use on-board sophisticated machine learning and AI to fuse that data to give us a full picture of what's above and below the surface," said Richard Jenkins, the founder and CEO of Saildrone, the company that makes the ships.

Submission + - Smallest Alien World Ever Seen Spotted by JWST in Stunning First (sciencealert.com)

Submitted by alternative_right
alternative_right writes: Around a newly formed star just 111 light-years away, the powerful space telescope has officially discovered its first exoplanet. It's called TWA-7b, and it's the smallest world that humanity has ever directly imaged.

TWA-7b is a cold gas giant with about a third of the mass of Jupiter, orbiting its red dwarf host star at a staggering distance – 52 times farther than Earth orbits the Sun. In our Solar System, that distance would place TWA-7b out in the Kuiper Belt, far beyond the orbit of Pluto.

Submission + - Researchers discover how caffeine could slow cellular aging (phys.org)

Submitted by alternative_right
alternative_right writes: A few years ago, the same research team found that caffeine helps cells live longer by acting on a growth regulator called TOR (target of rapamycin). TOR is a biological switch that tells cells when to grow, based on how much food and energy is available. This switch has been controlling energy and stress responses in living things for over 500 million years.

But in their latest study, the scientists made a surprising discovery: Caffeine doesn't act on this growth switch directly. Instead, it works by activating another important system called AMPK, a cellular fuel gauge that is evolutionarily conserved in yeast and humans.

Submission + - 'FuckLAPD.com' Lets Anyone Use Facial Recognition to Instantly Identify Cops (404media.co)

Submitted by alternative_right
alternative_right writes: The tool allows users to upload an image of a police officer’s face to search over 9,000 LAPD headshots obtained via public record requests. The site says image processing happens on the device, and no photos or data are transmitted or saved on the site. “Blurry, low-resolution photos will not match,” the site says.

Submission + - Carbon record reveals evidence of extensive human fire use 50,000 years ago (phys.org)

Submitted by alternative_right
alternative_right writes: To address this question, researchers from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS), alongside collaborators from China, Germany, and France, analyzed the pyrogenic carbon record in a 300,000-year-old sediment core from the East China Sea.

"Our findings challenge the widely held belief that humans only began influencing the environment with fire in the recent past, during the Holocene," said Dr. Zhao Debo, the study's corresponding author.

Submission + - Scientists May Have Finally Figured Out How Bats Avoid Cancer (sciencealert.com)

Submitted by alternative_right
alternative_right writes: Several bats species have been found to possess multiple copies of a known tumor-suppressing gene called p53. Humans have just a single copy, while other cancer-resistant animals, like elephants, boast up to 20. Mutations in this gene are linked to more than half of all human cancers

But a mechanism that's too aggressive at killing cells is obviously not desirable either. Thankfully, bats compensate with an overactive enzyme called telomerase, which allows their cells to continue to proliferate.

Journal Journal: Tech is broke and broken, science under threat

Journal by alternative_right

I should call these posts "the gateway to Hell" because I end up flirting with the most dangerous issues of our time. The conflict is where the growth is, I guess. I can feel the flames.

Tech is... boring. Sometime around Y2K the takeover by the same people who would have been eyeless MBAs in the 1980s began, and now Google and social media preside over a world that is basically as limited as 1980s four-channel television.

Submission + - One shot to stop HIV: MIT's bold vaccine breakthrough (sciencedaily.com)

Submitted by alternative_right
alternative_right writes: Researchers from MIT and Scripps have unveiled a promising new HIV vaccine approach that generates a powerful immune response with just one dose. By combining two immune-boosting adjuvants alum and SMNP the vaccine lingers in lymph nodes for nearly a month, encouraging the body to produce a vast array of antibodies. This one-shot strategy could revolutionize how we fight not just HIV, but many infectious diseases. It mimics the natural infection process and opens the door to broadly neutralizing antibody responses, a holy grail in vaccine design. And best of all, it's built on components already known to medicine.

Submission + - A Cracked Piece of Metal Self-Healed in Experiment That Stunned Scientists (sciencealert.com)

Submitted by alternative_right
alternative_right writes: "We certainly weren't looking for it. What we have confirmed is that metals have their own intrinsic, natural ability to heal themselves, at least in the case of fatigue damage at the nanoscale."

While the observation is unprecedented, it's not wholly unexpected. In 2013, Texas A&M University materials scientist Michael Demkowicz worked on a study predicting that this kind of nanocrack healing could happen, driven by the tiny crystalline grains inside metals essentially shifting their boundaries in response to stress.

Submission + - Florida Used a Nationwide Surveillance Camera Network 250 Times To Aid in Immigr (reason.com)

Submitted by alternative_right
alternative_right writes: The state of Florida, which leads the country in partnerships with Immigration and Customs Enforcement (ICE), is using a nationwide surveillance network of over 40,000 automatic license plate reader (ALPR) cameras present in over 5,000 communities across the United States to aid in immigration-related arrests.

Public records obtained by the Orlando Sentinel reveal that the Florida Highway Patrol (FHP) utilized Flock Safety ALPR camera data over 250 times between March 13 and May 5 (averaging about 32 times per week) for immigration-stated purposes. These searches spiked during "Operation Tidal Wave," a highly publicized, first-of-its-kind partnership between federal, state, and local law enforcement targeting undocumented individuals that led to the arrest of 1,120 people in Florida—only 63 percent of whom had previous criminal arrests or convictions.

Submission + - Axolotl Discovery Brings Us Closer Than Ever to Regrowing Human Limbs (sciencealert.com)

Submitted by alternative_right
alternative_right writes: A team of biologists from Northeastern University and the University of Kentucky has found one of the key molecules involved in axolotl regeneration. It's a crucial component in ensuring the body grows back the right parts in the right spot: for instance, growing a hand, from the wrist.
