Worlds Most Life Like Bionic Hand

lifelikebion

Brought to the world by prosthetics manufacturer Steeper, the innovative “bebionic” small hand is the latest model to come from the UK-based company, and it’s their most lifelike model yet. The artificial hand is the result of seven years of research and development, which involved not only the adoption of military technology but methods employed by Formula 1 engineers also. And the team certainly didn’t skimp on materials, either, exploiting rare Earth magnets for its patented finger control system and an aluminum alloy used in the construction of aircrafts to keep it lightweight.

Viagra To Help Treat Malaria?

The male impotence drug Viagra could also prevent malaria transmission, an in-vitro study demonstrates. The drug stiffens red blood cells infected with malaria. This should cause them to be removed from the blood by the spleen as part of its role in destroying old red blood cells and preventing them from being taken up by mosquitoes when they bite.

Plans to Launch 4000 Internet Satellites

Elon Musk is currently seeking government approval to begin testing on a project to broadcast the Internet from 4,000 satellites orbiting the Earth. He claims he wants to beam high-speed Internet to all corners of the world. The plan would transform SpaceX from a company based solely on rockets and spaceflight into an Internet provider.

Floating Metal Composites

Researchers have demonstrated a new metal matrix composite that is so light that it can float on water. A boat made of such lightweight composites will not sink despite damage to its structure. The new material also promises to improve automotive fuel economy because it combines light weight with heat resistance.

Single dose treatment for Malaria

A new antimalarial compound may be able to treat both current malarial infections and protect against future ones. The compound has a long active life and can target the parasite at several stages of its life cycle. Just one dose of the compound could be used to fight malaria infections in patients and increase their immunity against the parasite, according to the researchers.

From Single Cell to Multicellular organism

The leap from single-celled life to multicellular creatures is easier than we ever thought. And it seems there’s more than one way it can happen. The mutation of a single gene is enough to transform single-celled brewer’s yeast into a “snowflake” that evolves as a multicellular organism. Similarly, single-celled algae quickly evolve into spherical multicellular organisms when faced with predators that eat single cells.
