Patients are about to be enrolled in the first study to test a gene-editing technique known as CRISPR inside the body to try to cure an inherited form of blindness.

People with the disease have normal eyes but lack a gene that converts light into signals to the brain that enable sight.

The experimental treatment aims to supply kids and adults with a healthy version of the gene they lack, using a tool that cuts or “edits” DNA in a specific spot. It’s intended as a onetime treatment that permanently alters the person’s native DNA.

A second New Moon in the same month, a rising Mi;lky Way and the onset of meteor showers makes this a great time to get outside and looking up.

Right now, the robot is busy with the pre-launch preparations. August 22, F-850 will be launched to the ISS aboard the Soyuz MS-14 unmanned spacecraft. However, the humanoid robot won’t be staying on board long, after a ten-day mission F-850 is set to leave the station and return to Earth.

The field of cryonics — freezing the body after death to be revived in the future — is advancing with new technology and research. Now, the leading players in cryonics are gathering in South Florida to build interest and share new developments.

Research on robotic prostheses is coming along in leaps and bounds, but one hurdle is proving quite tricky to overcome: a sense of touch. Among other things, this sense helps us control our grip strength — which is vitally important when it comes to having fine motor control for handling delicate objects.

Enter a new upgrade for the LUKE Arm — named for Luke Skywalker, the Star Wars hero with a robotic hand. Prototype versions of this robotic prosthesis can be linked up to the wearer’s nerves.

New research from the USC Viterbi School of Engineering could be key to our understanding of how the aging process works. The findings potentially pave the way for better cancer treatments and revolutionary new drugs that could vastly improve human health in the twilight years.

The work, from Assistant Professor of Chemical Engineering and Materials Science Nick Graham and his team in collaboration with Scott Fraser, Provost Professor of Biological Sciences and Biomedical Engineering, and Pin Wang, Zohrab A. Kaprielian Fellow in Engineering, was recently published in the Journal of Biological Chemistry.

“To drink from the fountain of youth, you have to figure out where the fountain of youth is, and understand what the fountain of youth is doing,” Graham said. “We’re doing the opposite; we’re trying to study the reasons cells age, so that we might be able to design treatments for better aging.”

Sometimes the best discoveries happen when scientists least expect it. While trying to replicate another team’s finding, Stanford physicists recently stumbled upon a novel form of magnetism, predicted but never seen before, that is generated when two honeycomb-shaped lattices of carbon are carefully stacked and rotated to a special angle.

The authors suggest the magnetism, called orbital ferromagnetism, could prove useful for certain applications, such as quantum computing. The group describes their finding in the July 25 issue of the journal Science.

“We were not aiming for magnetism. We found what may be the most exciting thing in my career to date through partially targeted and partially accidental exploration,” said study leader David Goldhaber-Gordon, a professor of physics at Stanford’s School of Humanities and Sciences. “Our discovery shows that the most interesting things turn out to be surprises sometimes.”

Central London’s freshwater sources contain high levels of antibiotic resistant genes, with the River Thames having the highest amount, according to research by UCL.

The Regent’s Canal, Regent’s Park Pond and the Serpentine all contained the genes but at lower levels than the Thames, which contained genes providing resistance for bacteria to common antibiotics such as penicillin, erythromycin and tetracycline.

The genes come from bacteria in human and animal waste. When antibiotics are taken by humans much of the drug is excreted into the sewer system and then into freshwater sources. The presence of antibiotics in these water sources provides an environment where microbes carrying the resistance genes can multiply quicker and share their resistance with other microbes.
