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.

Incredible Recent Discoveries in Antarctica!

Posted by in category: space

The Moon rotates around the Earth at about the same speed, as it does around its axis, that’s why we can only see one side of it. It means that 41% of its surface hasn’t been explored yet! This fact surprises many people, as we are used to thinking that we know everything about all things in the world. While even our own planet remains a mystery to us.

Changing direction: Research team discovers switchable electronic chirality in an achiral Kagome superconductor

Posted by in categories: biological, chemistry, quantum physics

An international research team led by the Department of Microstructured Quantum Matter at the MPSD reports the first observation of switchable chiral transport in a structurally achiral crystal, the Kagome superconductor CsV3Sb5. Their work has been published in Nature.

Whether or not an object is indistinguishable from its mirror image has important consequences for its physical behavior. Say you watch a basketball player in a mirror. The ball, the player and their surroundings are, at first glance, just the same in the mirror as in real life. But if observed closely, some details are different. The ball in the player’s now appears in their left hand in the mirror. While the mirror image still shows the same hand, it has clearly changed from a left to a right hand or vice versa. Many other physical objects also have that differ in a key aspect, just like hands, which is why scientists call them handed or chiral (from Greek χϵρι = hand). Others, like the ball, cannot be distinguished from their mirror image, which makes them achiral.

Chirality is one of the most fundamental geometric properties and plays a special role in biology, chemistry and physics. It can cause surprising effects: One version of the carvone molecule, for example, produces a spearmint smell but its chiral—mirrored—equivalent smells of caraway.
