Astrobiologist: We Should Gene-Hack New Traits Into Mars Settlers

Posted by in categories: biotech/medical, ethics, genetics

Fellow webinar participant Christopher Mason, a geneticist at Weill Cornell Medicine, argued that gene-hacking astronauts could even be a moral imperative.

“And are we maybe ethically bound to do so?” Mason said. “I think if it’s a long enough mission, you might have to do something, assuming it’s safe, which we can’t say yet.”

Yale researchers create a new amphibious turtle robot with shape-shifting limbs

Posted by in categories: food, robotics/AI

The uses of such a robot include ocean farming, diver support, and monitoring of coastal ecosystems.

Yale University researchers in the U.S. have developed a new amphibious turtle robot that has the ability to transform its legs into flippers.

The amphibious robotic turtle, known as ART (Amphibious Robotic Turtle), was inspired by the land and aquatic turtles, a group whose fossil record dates back over 110 million years, according to a press release published by the university on Wednesday.

NASA detects the most powerful cosmic gamma-ray burst ever discovered

Posted by in category: space

On Sunday, October 9th, astronomers around the world were privy to an unusually bright and long-lasting pulse of high-energy radiation that swept over Earth, according to a NASA statement published on Thursday. The source of the event was a gamma-ray burst (GRB), one of the most luminous events ever known.

A Special Type of Diet Can Reduce Symptoms of Dementia

Posted by in categories: biotech/medical, food, neuroscience

Short cycles of a low-calorie diet that mimics fasting appeared to lower inflammation and delay cognitive decline in Alzheimer’s.

Alzheimer’s disease is a disease that attacks the brain, causing a decline in mental ability that worsens over time. It is the most common form of dementia and accounts for 60 to 80 percent of dementia cases. There is no current cure for Alzheimer’s disease, but there are medications that can help ease the symptoms.

Human Tetrachromacy is Real. Here’s What We Know

Posted by in category: genetics

After decades of exhaustive study, scientists have concluded that human tetrachromacy is real. Some people have a truly superhuman range of color vision. In fact, there are two distinct types of tetrachromacy. In some cases, it’s genetic. But in some rare cases, it can also be an acquired trait. While it’s difficult to test, enough tetrachromats have stepped forward that scientists now have visual and genetic tests for the condition.

One percent of the world’s population is thought to be tetrachromatic. These lucky folks may be able to see a thousand times as many colors as the rest of us trichromats. In order to test that idea, researcher Gabriele Johnson devised an experiment. She used precise amounts of pigment to create shades of paint that could only be distinguished by a machine — or a tetrachromat. In 2010, Johnson found a subject who was able to tell each subtle shade apart, every time — just as fast as trichromats could identify the colors they saw. “When you ask them to discriminate between the two mixtures, a tetrachromat can do it very quickly,” she said. “They don’t hesitate.”

Concetta Antico is a painter and art teacher with genetic tetrachromacy. Growing up in Sydney, she says, she was always “a little bit out of the box,” alone in her own visual dreamland. She always preferred the kaleidoscope of colors she saw when she looked at the natural world. But nobody else seemed to see it quite like she did. So she decided to paint what she saw. “I’m sure people just think I’m high on something all the time,” she said, “but I’m really just high on life and the beauty that’s around us.”

5 critical remote code execution vulnerabilities in Linux kernel.!Patch immediately!

Posted by in categories: computing, internet

The Linux kernel WiFi stack has five serious flaws, according to research, which a hacker might use to execute arbitrary code or inflict a denial of service.

The vulnerability, identified as CVE-2022–42719, was brought on by a use-after-free issue in the multi-BSSID element’s ieee802 11 parse elems full function of net/mac80211/util.c. A remote authenticated adversary might leverage this issue to execute arbitrary code or bring down the system by sending a carefully crafted request. In v5.2-rc1, the CVE-2022–42719 vulnerability was first made public.
