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.
New research hints at why some cancer cells develop drug resistance, and how to kill them.
A group of astronomers has snapped what is described as the most detailed image of the Moon ever snapped from the surface of Earth.
But doubts remain about whether cell reprogramming technique could one day help humans.
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.
A scientist is now aiming to prove that The Matrix is based on fact, and that the simulation we live in can be hacked.
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.
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.
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.
The proposal, titled “Bimodal NTP/NEP with a Wave Rotor Topping Cycle,” was put forward by Prof. Ryan Gosse, the Hypersonics Program Area Lead at the University of Florida and a member of the Florida Applied Research in Engineering (FLARE) team. Gosse’s proposal is one of 14 selected by the NAIC this year for Phase I development, which includes a $12,500 grant to assist in maturing the technology and methods involved. Other proposals included innovative sensors, instruments, manufacturing techniques, power systems, and more.
