The science behind why doing good makes us feel good

Posted by in categories: science, transportation

From lending someone a hand with their car to giving a simple “thank you” to a cashier, acts of kindness — whether big or small — can have a huge effect on both recipients and givers. Ali Rogin reports on insights into the power of these acts.

Neuralink, Elon Musk’s brain implant startup, quietly raises an additional $43M

Posted by in categories: computing, Elon Musk, finance, neuroscience

Neuralink, the Elon Musk-founded company developing implantable chips that can read brain waves, has raised an additional $43 million in venture capital, according to a filing with the SEC.

The filing published this week shows the company increased its previous tranche, led by Peter Thiel’s Founders Fund, from $280 million to $323 million in early August. Thirty-two investors participated, according to the filing.

Neuralink hasn’t disclosed its valuation recently. But in June, Reuters reported that the company was valued at about $5 billion after privately-executed stock trades.

Biohybrid microrobots could remove micro- and nano-plastics from aquatic environments

Posted by in categories: food, habitats, nanotechnology

Seas, oceans, rivers, and other bodies of water on Earth have become increasingly polluted over the past decades, and this is threatening the survival of many aquatic species. This pollution takes a wide range of forms, including the proliferation of so-called micro and nano plastics.

As suggested by their name, micro and nano plastics are harmful tiny particles derived from the disintegration of waste released into the water. These particles have been found to disrupt aquatic ecosystems, for instance, delaying the growth of organisms, reducing their food intake, and damaging fish habitats.

Devising effective technologies to effectively remove these tiny particles is of utmost importance, as it could help to protect endangered species and their natural environments. These technologies should be carefully designed to prevent further pollution and destruction; thus, they should be based on environmentally friendly materials.

‘Adopt an axolotl’ campaign launches in Mexico to save iconic species

Posted by in categories: habitats, health

MEXICO CITY (AP) — Ecologists from Mexico’s National Autonomous university on Friday relaunched a fundraising campaign to bolster conservation efforts for axolotls, an iconic, endangered fish-like type of salamander.

The campaign, called “Adoptaxolotl,” asks people for as little as 600 pesos (about $35) to virtually adopt one of the tiny “water monsters.” Virtual adoption comes with live updates on your axolotl’s health. For less, donors can buy one of the creatures a virtual dinner.

In their main habitat the population density of Mexican axolotls (ah-ho-LOH’-tulz) has plummeted 99.5% in under two decades, according to scientists behind the fundraiser.

Triggered self-assembly of magnetic nanoparticles

Posted by in categories: biotech/medical, nanotechnology, Ray Kurzweil

One of ray kurzweils wonder machines are already here self assembled nanobots called foglet machines. This could allow for future avatars that people could pilot for daily life.

Colloidal magnetic nanoparticles are candidates for application in biology, medicine and nanomanufac-turing. Understanding how these particles interact collectively in fluids, especially how they assemble and aggregate under external magnetic fields, is critical for high quality, safe, and reliable deployment of these particles. Here, by applying magnetic forces that vary strongly over the same length scale as the colloidal stabilizing force and then varying this colloidal repulsion, we can trigger self-assembly of these nanoparticles into parallel line patterns on the surface of a disk drive medium. Localized within nanometers of the medium surface, this effect is strongly dependent on the ionic properties of the colloidal fluid but at a level too small to cause bulk colloidal aggregation.

“Luna is a twenty-first-century penal colony but, since no one can stand Earth gravity after being on the moon for a few weeks, all who are sent there must stay. When the liberated people rise against the authority, they receive unexpected help from a computer with a personality.“
