Scientists have claimed to make a breakthrough that would be “one of the holy grails of modern physics” – but experts have urged caution about the results.

In recent days, many commentators have become excited by two papers that claim to document the production of a new superconductor that works at room temperature and ambient pressure. Scientists in Korea said they had synthesised a new material called LK-99 that would represent one of the biggest physics breakthroughs of recent decades.

Superconductors are a special kind of material where electrical resistance vanishes, and which throw out magnetic fields. They are widely useful, including in the production of powerful magnets and in reducing the amount of energy lost as it moves through circuits.

The wings of a butterfly are made of chitin, an organic polymer that is the main component of the shells of arthropods like crustaceans and other insects. As a butterfly emerges from its cocoon in the final stage of metamorphosis, it will slowly unfold its wings into their full grandeur.

During the unfolding, the chitinous material becomes dehydrated while blood pumps through the veins of the butterfly, producing forces that reorganize the molecules of the material to provide the unique strength and stiffness necessary for flight. This natural combination of forces, movement of water, and molecular organization is the inspiration behind Associate Professor Javier G. Fernandez’s research.

Alongside fellow researchers from the Singapore University of Technology and Design (SUTD), Fernandez has been exploring the use of chitinous polymers as a sustainable material for engineering applications.

Exercise gives your brain a “bubble bath of neurochemicals,” says Wendy Suzuki, a professor of neural science.

Exercise can have surprisingly transformative impacts on the brain, according neuroscientist Wendy Suzuki. It has the power not only to boost mood and focus due to the increase in neurotransmitters like dopamine, serotonin, and noradrenaline, but also contributes to long-term brain health. Exercise stimulates the growth of new brain cells, particularly in the hippocampus, improving long-term memory and increasing its volume. Suzuki notes that you don’t have to become a marathon runner to obtain these benefits — even just 10 minutes of walking per day can have noticeable benefits. It just takes a bit of willpower and experimentation.

Dark matter isn’t just floating around filling up empty space. Importantly, it is found in clumps and structures, similar to ordinary matter. It forms the structure onto which ordinary matter gloms and is thought to be responsible for the structures of galaxies and the universe as a whole.

“We know that galaxies form in the scaffold that dark matter produces,” astronomer and early universe researcher Steve Wilkins of the University of Sussex explained. “It is an integral part of our universe to explain what we see.”

“We don’t have a firm theoretical handle on what dark matter should be.”

Our Solar System is a pretty busy place. There are millions of objects moving around – everything from planets, to moons, to comets, and asteroids. And each year we’re discovering more and more objects (usually small asteroids or speedy comets) that call the Solar System home.

Astronomers had found all eight of the main planets by 1846. But that doesn’t stop us from looking for more. In the past 100 years, we’ve found smaller distant bodies we call dwarf planets, which is what we now classify Pluto as.

The discovery of some of these dwarf planets has given us reason to believe something else might be lurking in the outskirts of the Solar System.

Summary: Researchers created a revolutionary tiny and efficient thermoelectric device, which can help amputees feel temperature with their phantom limbs.

Known as the wearable thin-film thermoelectric cooler (TFTEC), this device is lightweight, incredibly fast, and energy-efficient, potentially revolutionizing applications such as prosthetics, augmented reality haptics, and thermally-modulated therapeutics. Additionally, this technology has potential in industries like electronics cooling and energy harvesting in satellites.

The study conducted to test the TFTEC demonstrated its ability to elicit cooling sensations in phantom limbs, doing so significantly faster, with more intensity, and less energy than traditional thermoelectric technology.

Watch more interviews on the mystery of consciousness: https://bit.ly/41Bs4NV

How can consciousness be addressed scientifically? The Tucson conference, founded in 1994 and celebrating its 20th anniversary in 2014, exemplifies the quest. What are the range of theories? Where do participants position themselves? Meet the founders, early visionaries, new scientists and thinkers. Progress is being made, but what does this really mean?

Fragile X syndrome is a genetic disorder caused by a mutation in a gene that lies at the tip of the X chromosome. It is linked to autism spectrum disorders.

People with fragile X experience a range of symptoms that include cognitive impairment, developmental and speech delays and hyperactivity. They may also have some physical features such as large ears and foreheads, flabby muscles and poor coordination.

Along with our colleagues Jonathan Watts and Elizabeth Berry-Kravis, we are a team of scientists with expertise in molecular biology, nucleic acid chemistry and pediatric neurology.
