Scientists develop RNA-targeting strategy to repair genetic cause of ALS and dementia

Posted by in categories: biotech/medical, genetics, health, neuroscience

Scientists at University of Florida (UF) Scripps Biomedical Research have developed a potential medicine for a leading cause of ALS and dementia that works by eliminating disease-causing segments of RNA. The compound restored the health of neurons in the lab and rescued mice with the disease.

The potential medication is described this week in the scientific journal Proceedings of the National Academy of Sciences. It is designed to be taken as a pill or an injection, said the lead inventor, professor Matthew Disney, Ph.D., chair of the UF Scripps chemistry department. Importantly, experiments showed that the compound is small enough to cross the blood-brain barrier, a hurdle other approaches have failed to clear, he said.

Amyotrophic lateral sclerosis, or ALS, progressively destroys neurons that control muscles, leading to worsening muscle loss and eventually death. The mutation, a leading cause of inherited ALS, is referred to as “C9 open reading frame 72,” or C9orf72. This mutation also leads to one form of frontotemporal dementia, a brain disease that causes the brain’s frontal and to shrink, resulting in changes in personality, behavior and speech, ultimately resulting in death.

Combination of ultrasound and nanobubbles destroys cancerous tumors

Posted by in category: biotech/medical

A new technology developed at Tel Aviv University (TAU) makes it possible to destroy cancerous tumors in a targeted manner via a combination of ultrasound and the injection of nanobubbles into the bloodstream.

According to the research team, this latest technology enables the destruction of the tumor in a non-invasive manner, unlike invasive treatment methods or the injection of microbubbles into the tumor itself.

In Space-Mengtian Lab Module/Astronauts

Posted by in categories: habitats, health, space

In space — Recent (China Manned Space Agency — No access Chinese mainland) 1. Various of Shenzhou-14 astronaut Cai Xuzhe unpacking packages 2. Various of Shenzhou-14 crew checking facilities, opening boxes and inspecting equipment 3. Shenzhou-14 crew installing and trying out microgravity resistance exercise device 4. Shenzhou-14 astronaut Liu Yang exercising with microgravity resistance exercise device.

The Shenzhou-14 astronauts have completed several missions over the last two weeks, including the installation of equipment in the work area of the Mengtian lab module which they entered for the first time on Nov. 3. Among the scientific and basic living equipment, the astronauts have also set up a small home gym to help them stay fit. The crew members-Chen Dong, Liu Yang and Cai Xuzhe can now keep fit in the lab with a special microgravity resistance exercise device similar to a rowing machine with which astronauts can do squats, heel lifts, hard pulls, rowing and shoulder exercise. Resistance exercise is especially important for astronauts living in zero gravity conditions which can rapidly reduce muscle mass and bone density.

On Sunday, the trio entered the Tianzhou-5 cargo craft to fetch supplies for the Tiangong space station.

This series looks at devices and concepts we may see in future conflicts, and we will look at both hypothetical technologies and those limitations placed on us by fighting in space, for instance, rather than on the ground.

Quantum computing pioneer D-Wave looks at the technology’s past, present and future

Posted by in categories: computing, quantum physics

Check out the on-demand sessions from the Low-Code/No-Code Summit to learn how to successfully innovate and achieve efficiency by upskilling and scaling citizen developers. Watch now.

Quantum computing could be a disruptive technology. It’s founded on exotic-sounding physics and it bears the promise of solving certain classes of problems with unprecedented speed and efficiency. The problem, however, is that to this day, there has been too much promise and not enough delivery in the field, some say. Perhaps with the exception of D-Wave.

The company that helped pioneer quantum computing over 15 years ago has clients such as BASF, Deloitte, Mastercard and GlaxoSmithKline today. Alan Baratz went from running D-Wave’s R&D to becoming its CEO, taking the company public while launching products and pursuing new research directions.

Scientists Accidentally Discover Weight Loss Therapy After Mice Start Sweating Fat From Their Skin

Posted by in category: biotech/medical

Accidental science is the best. One of the greatest lifesaving drugs in history – penicillin – was discovered purely by accident, and such experiments truly show how intricate and unpredictable science is.

So, when researchers from the University of Pennsylvania began their journey looking for a type 2 diabetes treatment and stumbled across a potentially incredible weight-loss treatment, needless to say, they were more than surprised.

The researchers describe their new results in a paper in the journal Science, in which they applied a treatment to a group of lab mice in the pursuit of counteracting type 2 diabetes. Instead of performing as expected, the experiment took a surprising turn – the mice started secreting a slimy substance through their skin.

Psychedelics: Chemicals, Consciousness, and Creativity

Posted by in categories: chemistry, neuroscience

Could psychedelics make you more creative? Shift your mind, connect you to others, and help you access a younger, more malleable version of yourself? Activist Rick Doblin, neuroscientist Gül Dölen, and musician Reggie Watts join Brian Greene for a mind-bending and multidisciplinary conversation about the promises and pitfalls of these “magic” molecules and their impact on creativity, connection, and consciousness.

This program is part of the Big Ideas series, supported by the John Templeton Foundation.

A cutting-edge radar system could be a front-line tool to fight dangerous space junk

Posted by in categories: mapping, satellites

Plenty of potential solutions have been put forward to deal with the problem, but they all face a similar problem at the first step: how to track the debris they’re attempting to eliminate. Enter a new idea from researchers in Iran — using a novel type of radar to detect and track space debris before it becomes a danger.

The novel type of radar is called inverse synthetic aperture radar, or ISAR. As one might expect from the name, it’s the opposite of synthetic aperture radar (SAR). SAR has become much more prominent lately, especially by satellites attempting to collect data about the Earth, especially terrain data that might be useful for geospatial mapping.
