China has announced a milestone in the development of clean, sustainable energy by setting a new world record for the longest duration of temperatures needed for fusion to occur.

The Experimental Advanced Superconducting Tokamak (EAST) located in Hefei, Anhui Province, is the successor to HT-7, China’s first superconducting tokamak, which retired in 2013. The Hefei Institutes of Physical Science (HIPS) is conducting the experiment for the Chinese Academy of Sciences (CAS).

Professor Gong Xianzu, a researcher at the CAS Institute of Plasma Physics (IPP) who is leading the project, announced the breakthrough. The reactor achieved not one but two milestones. Firstly it reached a plasma temperature of 120 million degrees Celsius for 101 seconds. This is 20% hotter and five times longer than last year, when EAST managed 100 million degrees Celsius for 20 seconds. Secondly, it reached an even higher peak temperature of 160 million degrees Celsius, lasting for 20 seconds.

Culture drives human evolution more than genetics

I wonder about the thought that only humans do this, and perhaps that somehow culture is separate in some way from biological evolution enmeshed with the rest of the planet?
by University of Maine

Culture is an under-appreciated factor in human evolution, Waring says. Like genes, culture helps people adjust to their environment and meet the challenges of survival and reproduction. Culture, however, does so more effectively than genes because the transfer of knowledge is faster and more flexible than the inheritance of genes, according to Waring and Wood.

Waring and Wood say culture is also special in one important way: it is strongly group-oriented. Factors like conformity, social identity and shared norms and institutions—factors that have no genetic equivalent—make cultural evolution very group-oriented, according to researchers. Therefore, competition between culturally organized groups propels adaptations such as new cooperative norms and social systems that help groups survive better together.

According to researchers, “culturally organized groups appear to solve adaptive problems more readily than individuals, through the compounding value of social learning and cultural transmission in groups.” Cultural adaptations may also occur faster in larger groups than in small ones.

In a recent interview, Elon Musk stated that the human language could possibly end within five to ten years. The CEO of Neuralink went to talk with Joe Rogan, implying that with the innovation of the brain chip the company is currently developing, humans won’t have to speak anymore using traditional languages.

Neuralink develops a chip that will soon be able to attach to the human brain. The chip’s invention aimed to communicate faster and conveniently. Through a single universal language, Elon Musk believes that the way we talk today will soon improve. The brain chip is expected to be completed to be developed within a few years, and by then, our communication could possibly evolve.

Elon Musk stated that the Neuralink chip’s success may take a while, but it should take five to ten years if the development will accelerate. He also added that the progress of the brain chip is on track, but with only to focus on their current objective, which is to help people minimize and prevent brain injuries, Express reported.

New image made using NASA ’s Chandra X-Ray Observatory hints at previously unknown interstellar energy source at the Milky Way center.

New research by University of Massachusetts Amherst astronomer Daniel Wang reveals, with unprecedented clarity, details of violent phenomena in the center of our galaxy. The images, published recently in Monthly Notices of the Royal Astronomical Society, document an X-ray thread, G0.17–0.41, which hints at a previously unknown interstellar mechanism that may govern the energy flow and potentially the evolution of the Milky Way.

“The galaxy is like an ecosystem,” says Wang, a professor in UMass Amherst’s astronomy department, whose findings are a result of more than two decades of research. “We know the centers of galaxies are where the action is and play an enormous role in their evolution.” And yet, whatever has happened in the center of our own galaxy is hard to study, despite its relative proximity to Earth, because, as Wang explains, it is obscured by a dense fog of gas and dust. Researchers simply can’t see the center, even with an instrument as powerful as the famous Hubble Space Telescope. Wang, however, has used a different telescope, NASA’s Chandra X-Ray Observatory, which “sees” X-rays, rather than the rays of visible light that we perceive with our own eyes. These X-rays are capable of penetrating the obscuring fog — and the results are stunning.

The applications are for trademarks for the company’s ‘T’ logo design “and two other iterations of ‘Tesla’ stylised logo for use in the food industry”, the report said.

Moneycontrol could not independently verify the report.

As per the report, the three applications are for “restaurant services, pop-up restaurant services, self-service restaurant services, take-out restaurant services” and are filed under a trademark law provision indicating that Tesla intends to use, but has not done so yet.

This in turn led the team to an FDA-approved drug called Sirturo, which is used to treat tuberculosis and works by targeting this process in bacteria. In vivo animal experiments showed that the drug could target the fuel supply of these ultra-fit cancer cells and selectively create a “power failure” in them, while leaving healthy cells unharmed. This blocked 85 percent of metastasis in the animal experiments.

Leveraging a newfound ability to identify the “fittest” metastatic cancer cells, scientists at the UK’s University of Salford have discovered that an already approved drug can be deployed to cut off their fuel supply, while leaving normal healthy cells unharmed.

Metastatic cancer cells are dangerous, fast-moving cells cancer cells that have spread away from the primary site to other parts of the body where they can give rise to new tumors. These cells have often already survived chemotherapy and radiation treatments which makes tackling them difficult, though scientists continue to learn more about their behavior and how they might be targeted for better outcomes.

Research has shown that part of the reason these cells are able to resist treatments and spread throughout the body is because they are the fittest cancer cells, and therefore require relatively large amounts of energy. Building on this, the University of Salford scientists used an advanced biosensor to measure energy-carrying molecules in cells called ATP which, for the first time, enabled them to identify which of these cells are the “fittest.”

The team says that the technique could be used to develop new vaccines against antibiotic-resistant bacteria, and potentially even wipe out some dangerous strains in a similar way to how smallpox was eradicated.

Pathogens like bacteria and viruses are extremely good at evolving in response to drugs, which can render vaccines ineffective. But now, researchers at ETH Zurich have found a way to weaponize that ability against them, forcing the bugs down harmless evolutionary dead ends.

Microbes are living examples of evolution in action. Darwin’s classic theory says that when lifeforms are exposed to pressures from their environment, some of them will develop new genetic mutations that help them cope better. Since other individuals will be at a disadvantage, the mutations will eventually become the norm throughout a population.
