Self-powered implantable device stimulates fast bone healing, then disappears without a trace

Posted by in categories: biotech/medical, innovation

In 2017, Green Bay Packers quarterback Aaron Rodgers broke his right collarbone in a game against the Minnesota Vikings. Typically, it takes about 12 weeks for a collarbone to fully heal, but by mid-December fans and commentators were hoping the three-time MVP might recover early and save a losing season.

So did Xudong Wang, a professor of materials science and engineering at the University of Wisconsin-Madison and an expert in creating thin, movement-powered medical devices. “I started wondering if we could provide a new solution to bring athletes back to the field quicker than ever,” Wang says.

Researchers know that electricity can help speed up bone healing, but “zapping” fractures has never really caught on, since it requires surgically implanting and removing electrodes powered by an external source.

Common Mechanism Underlies Some Behavioral Traits Seen in Autism and Schizophrenia

Posted by in categories: biotech/medical, genetics, robotics/AI

The researchers also showed that they could restore normal cognitive function in mice with these genetic mutations by artificially turning down hyperactivity in neurons of the AD thalamus. The approach they used, chemogenetics, is not yet approved for use in humans. However, it may be possible to target this circuit in other ways, the researchers say.


Summary: Certain genes that are mutated or missing in those with schizophrenia and autism cause similar dysfunction in neural networks within the thalamus.

Smart foam material gives robotic hand the ability to self-repair

Posted by in categories: materials, robotics/AI

Tee said AiFoam is the first of its kind to combine both self-healing properties and proximity and pressure sensing. After spending over two years developing it, he and his team hope the material can be put to practical use within five years.


SINGAPORE, July 6 (Reuters) — Singapore researchers have developed a smart foam material that allows robots to sense nearby objects, and repairs itself when damaged, just like human skin.

Artificially innervated foam, or AiFoam, is a highly elastic polymer created by mixing fluoropolymer with a compound that lowers surface tension.

Unusual Comet – 1000 Times More Massive Than Typical – Discovered in Outer Solar System

Posted by in category: space

Estimated to be 100–200 kilometers across, the unusual wandering body will make its closest approach to the Sun in 2031.

A giant comet from the outskirts of our Solar System has been discovered in 6 years of data from the Dark Energy Survey. Comet Bernardinelli-Bernstein is estimated to be about 1000 times more massive than a typical comet, making it arguably the largest comet discovered in modern times. It has an extremely elongated orbit, journeying inward from the distant Oort Cloud over millions of years. It is the most distant comet to be discovered on its incoming path, giving us years to watch it evolve as it approaches the Sun, though it’s not predicted to become a naked-eye spectacle.

Astronomers Detect a Lurking Cosmic Cloud, Bigger Than The Entire Milky Way

Posted by in category: space

In the yawning vacuum of intergalactic space, something large is lurking.

Not a galaxy, although it’s of a comparable size: A vast cloud of hot, faintly glowing gas, bigger than the Milky Way, in the space between galaxies congregating in a huge cluster.

Scientists believe this cloud may have been unceremoniously stripped from a galaxy in the cluster, the first gas cloud of this kind we’ve ever seen. Even more surprisingly, it hasn’t dissipated, but has remained clumped together for hundreds of millions of years.

ISS researchers repaired DNA in space using CRISPR/Cas9 genome editing

Posted by in category: biotech/medical

Researchers aboard the ISS have announced the first successful use in space for a new technique for studying DNA repair in yeast. Astronauts aboard the space station have demonstrated a successful CRISPR/Cas9 genome editing method. An organism can suffer damaged DNA occurring during normal biological processes or as the result of environmental causes.

In both humans and animals, damaged DNA can lead to cancer. However, there are multiple natural strategies inside cells that allow damaged DNA to be repaired. NASA is working hard on studying DNA repair in space because astronauts traveling outside of the atmosphere have an increased risk of DNA damage due to ionizing radiation.

Until now, technological and safety obstacles have limited research into the issue. Now astronauts aboard the ISS have developed a new method for studying DNA repair in yeast cells that can be conducted completely in space. The process uses CRISPR/Cas9 genome editing technology to create precise damage in DNA strands to allow DNA repair mechanisms to be observed.

European Robotic Arm

Posted by in categories: robotics/AI, space

Concept I introduced long ago in TMP2 as the Inchworm orbital service robot is now being demonstrated by the ESA with the new Russian addition to the ISS.


It is much like a human arm. It has an elbow, shoulders and even wrists. The European Robotic Arm (ERA) is the first robot able to ‘walk’ around the Russian segment of the International Space Station.

Light yet powerful, the orbital arm has the ability to anchor itself to the Station and move back and forward by itself, hand-over-hand between fixed base-points. This space robot looks like a pair of compasses and has a length of over 11 m. When stretched, it could pass a football from a penalty spot to the goalkeeper.

Scientists discover plant ‘brain’ controlling seed development

Posted by in category: neuroscience

Circa 2017


A new study by scientists at the University of Birmingham has revealed a group of cells that function as a ‘brain’ for plant embryos, capable of assessing environmental conditions and dictating when seeds will germinate.

A plant’s decision about when to germinate is one of the most important it will make during its life. Too soon, and the plant may be damaged by harsh winter conditions; too late, and it may be out-competed by other, more precocious plants.
