Researchers from the Julius-Maximilians-Universität Würzburg (JMU) have developed a portable, radiation-free scanner using Magnetic Particle Imaging (MPI). This technique, capable of visualizing dynamic processes like blood flow in the human body, is based on the detection of magnetic nanoparticles administered as markers.Technologies like computed tomography, magnetic resonance imaging, positron emission tomography, and ultrasound are now integral parts of the medical domain, offering exclusive insights into human…

Researchers have developed a device that can disrupt the relationship between the absorption and emission efficiencies of an object, essentially violating Kirchhoff’s law of thermal radiation. This law, in place for over 150 years, states that an object’s ability to absorb and emit energy is equal at each wavelength and angle of incidence. This breakthrough could significantly impact sustainable energy harvesting systems and certain types of camouflage technology. (Artist’s concept.)Scientists have developed a device that…

Researchers investigated ‘super corals’ to understand their potential in countering the effects of climate change on coral reefs. The study reveals that while ‘super corals’ show significant resilience, this adaptation comes at a cost, including reduced genetic diversity and skeletal compromises. These discoveries challenge existing notions about coral resilience and underline the importance of considering genetic diversity and adaptability in restoration efforts.Scientists are studying ‘super corals’ as a potential…

A schematic Illustration of Structural-controlled Pt-high-entropy-alloy (Pt-HEA) Model Catalyst Synthesis. Credit: Yoshihiro Chida et al.A research team has developed a new platform to study and control the atomic-level structure of high-entropy alloys’ surfaces. They found that platinum high-entropy alloys outperformed platinum-cobalt alloys in oxygen reduction reaction. These findings have broad applicability, and the team plans to use this platform for practical electrocatalysis in the future.High-entropy alloys…

It’s been three years since the Laser Interferometric Gavitational-Wave Observatory (LIGO) went down for some major upgrades. Now, LIGO is finally up and running again, and this time it’s ready to help fully decipher the mysteries of gravitational waves. But what exactly is LIGO, and what mysteries can it help us solve?

An international effort to revive an ancient roundworm, frozen in Siberian permafrost for millennia, has unleashed a lifeform even older than scientists once thought.In 2018, several resurrected nematodes, of the genus Panagrolaimus, were dated to around 32,000 years old. But now, more precise radiocarbon dating suggests these soil worms have remained 'dead awake' in parts of Siberia since at least the late Pleistocene, around 46,000 years ago.If correct, the record absolutely smashes the longest known state of extreme…

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…
