Researchers discover a link between bacteria in the mouth and deadly brain abscesses

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

The inside of a person’s mouth can say a lot about their overall health. Studies have established links between poor oral health and conditions like heart disease, high blood pressure and pneumonia. Now, a new study shows there’s a connection to the brain. Researchers in the U.K. found certain bacteria in the mouth may cause deadly brain abscesses.

The Next Step for AI in Biology Is to Predict How Proteins Behave in the Body

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

This shapeshifting controls the biological processes of living things—for example, opening the protein tunnels dotted along neurons or driving cancerous growth. But it also makes understanding protein behavior and developing drugs that interact with proteins a challenge.

While recent AI breakthroughs in the prediction (and even generation) of protein structures are a huge advance 50 years in the making, they still only offer snapshots of proteins. To capture whole biological processes—and identify which lead to diseases—we need predictions of protein structures in multiple “poses” and, more importantly, how each of these poses changes a cell’s inner functions. And if we’re to rely on AI to solve the challenge, we need more data.

Thanks to a new protein atlas published this month in Nature, we now have a great start.

Israeli scientists say substance prevents cancer’s spread in mice with 90% success

Posted by in category: biotech/medical

Israeli scientists are aiming to produce the world’s first preventative drug designed to stop tumors causing secondary cancer, and say the active ingredient has shown more than 90 percent effectiveness in mice.

The Bar Ilan University research team produced a peptide — a chain of amino acids — made to stop cancer cells from entering the blood and therefore halting them from moving around the body.

They have published peer-reviewed research showing that it successfully prevented metastasis in mice, meaning it prevented the spread of diseased cells that can cause secondary cancer.

Scientists make new discovery about reversing the ageing process

Posted by in categories: biotech/medical, genetics, life extension

Researchers look at DNA of lab mice and ultimately reverse ageing process Related: Empowered Aging Scientists have made a new discovery about how to reverse the ageing process through looking at the way in which cells in DNA are organised. In a new study published in Cell, David Sinclair, who is a professor of genetics at Harvard Medical School, and his team described how they looked at a genome, which is called epigenome, in mice to study the ageing process.

New Nuclear Rocket Design to Send Missions to Mars in Just 45 Days

Posted by in categories: bioengineering, military, nuclear energy, space

We live in an era of renewed space exploration, where multiple agencies are planning to send astronauts to the Moon in the coming years. This will be followed in the next decade with crewed missions to Mars by NASA and China, who may be joined by other nations before long. These and other missions that will take astronauts beyond Low Earth Orbit (LEO) and the Earth-Moon system require new technologies, ranging from life support and radiation shielding to power and propulsion. And when it comes to the latter, Nuclear Thermal and Nuclear Electric Propulsion (NTP/NEP) is a top contender!

NASA and the Soviet space program spent decades researching nuclear propulsion during the Space Race. A few years ago, NASA reignited its nuclear program for the purpose of developing bimodal nuclear propulsion – a two-part system consisting of an NTP and NEP element – that could enable transits to Mars in 100 days. As part of the NASA Innovative Advanced Concepts (NIAC) program for 2023, NASA selected a nuclear concept for Phase I development. This new class of bimodal nuclear propulsion system uses a “wave rotor topping cycle” and could reduce transit times to Mars to just 45 days.

World’s first ammonia-electric semi packs as much energy as the Tesla

Posted by in categories: energy, transportation

Claiming a system-level energy density 5X higher than batteries, Amogy has rolled out “the world’s first ammonia-powered, zero-emission semi truck.” It holds about 900 kWh of energy, like the Tesla Semi, but you can refuel it in about eight minutes.
