Spacecraft with their own magnetic fields could be used in the future as a means to protect human astronauts from damaging effects of radiation.
In recent years, roboticists and material scientists worldwide have been trying to create artificial systems that resemble human body parts and reproduce their functions. These include artificial skins, protective layers that could also enhance the sensing capabilities of robots.
Researchers at Donghua University in China and the Jülich Centre for Neutron Science (JCNS) in Germany have recently developed a new and highly promising artificial ionic skin based on a self-healable elastic nanomesh, an interwoven structure that resembles human skin. This artificial skin, introduced in a paper published in Nature Communications, is soft, fatigue-free and self-healing.
“As we know, the skin is the largest organ in the human body, which acts as both a protective layer and sensory interface to keep our body healthy and perceptive,” Shengtong Sun, one of the researchers who carried out the study, told TechXplore. “With the rapid development of artificial intelligence and soft robotics, researchers are currently trying to coat humanoid robots with an ‘artificial skin’ that replicates all the mechanical and sensory properties of human skin, so that they can also perceive the everchanging external environment like us.”
“Almost every male character so far is a coward, a jerk or both,” he posted to Twitter. “Tolkien is turning in his grave.”
Amazon aired the first two episodes of Rings of Power on Friday, which centered on Galadriel, commander of the Northern Armies, bent on exacting vengeance for the death of her brother centuries earlier. By comparison, fellow elf Elrond prefers his life of quiet counsel to King Gil-galad, who attempts to send Galadriel away to avoid any military skirmish with Sauron’s scattered forces.
The debate over Amazon’s Rings of Power began in earnest after showrunners and studio executives argued in Vanity Fair they needed to take liberties when adapting Tolkien characters such as Galadriel and Elrond, since his Middle-earth was badly in need of an update to reflect today’s more modern societies.

Just a few decades ago, scientists were absolute in their determination that time began with the Big Bang. But that’s all been turned on its head with the rise of string theory and other fascinating developments in theoretical physics. Learn how those advances brought the pre-Bang universe to the forefront of cosmology.

A year back and bodily function improves, and it’s a shot rather than transfusion as needed from other plasma treatments.
Researchers have found that intramuscular injections of plasma concentrate made from human umbilical cord blood improve various health biomarkers and decrease biological age in elderly people [1].
Circulating proteins have a significant impact on our health, and blood plasma transfusion is increasingly used against inflammatory conditions as well as some autoimmune and genetic diseases [2]. Basically, plasma transfusion enables physicians to alter the concentration of interesting molecules in the blood.

The popularity of electric vehicles (EVs) as an environmentally friendly alternative to conventional gasoline vehicles has been on the rise. This has led to research efforts directed toward developing high-efficiency EV batteries. But, a major inefficiency in EVs results from inaccurate estimations of the battery charge. The charge state of an EV battery is measured based on the current output of the battery. This provides an estimate of the remaining driving range of the vehicles.
Typically, the battery currents in EVs can reach hundreds of amperes. However, commercial sensors that can detect such currents cannot measure small changes in the current at milliampere levels. This leads to an ambiguity of around 10% in the battery charge estimation. What this means is that the driving range of EVs could be extended by 10%. This, in turn, would reduce inefficient battery usage.
Now, a team of researchers from Japan, led by Professor Mutsuko Hatano from Tokyo Institute of Technology (Tokyo Tech), has now come up with a solution. In their study published in Scientific Reports, the team has reported a diamond quantum sensor-based detection technique that can estimate the battery charge within 1% accuracy while measuring high currents typical of EVs.
Housing the world’s rapidly-growing population will require massive urban expansion and lots of concrete and steel, but these materials have a huge carbon footprint. A shift to building cities out of wood could avoid more than 100 billion tons of CO2 emissions, according to a new study.
Replacing reinforced concrete with timber might sound unwise, but innovations in engineered wood mean it’s now feasible to construct multi-story buildings without traditional materials. So-called “mass timber” is increasingly being used for structural and load-bearing elements in mid-rise developments, which refers to buildings between 4 and 12 stories high.
One of the main selling points of mass timber is that it’s much less carbon-intensive than steel and cement. In theory it’s actually carbon negative, because trees absorb CO2 in the process of producing wood. But question marks have remained over exactly how much more climate-friendly wood-based construction is, and what impact demand for timber could have on the environment.

Galadriel is one of the female stars of the show.
Amazon has invested $1 billion in “The Lord of the Rings: The Rings of Power” series inspired by the world of J.R.R. Tolkien, and former company executives told Insider the company will use the show to determine if Amazon Studios is a worthwhile venture for the company.
After NASA scrubbed it’s uncrewed Artemis 1 mission due to hydrogen leakage problem, SpaceX CEO Elon Musk shares a possible solution.
On Saturday, NASA called off Artemis 1 launch because of Hydrogen leakage. Engineers spent around 3 hours to fix the problem but ultimately failed and the launch was cancelled. The current launch window will close on Tuesday and if NASA failed to fix the problem before that then they have to wait until late September or early October for launch.
NASA said “Because of the complex orbital mechanics involved in launching to the Moon, we would have had to launch Artemis I by Tuesday, Sept. 6 as part of the current launch period”.

Einstein’s theory of general relativity has made countless correct predictions and yet physicists are constantly trying to prove it wrong. Why? What would it be good for to prove Einstein wrong? And how could it be done? In this video I go through the most promising experiments that physicists currently work on which could prove Einstein wrong.
