New Hope for Neurological Disorders: Scientists Have Discovered How an Essential Nutrient Enters the Brain

Posted by in categories: biotech/medical, neuroscience

Researchers have discovered the process by which dietary choline crosses the blood-brain barrier. This breakthrough has potential applications in enhancing drug delivery to the brain for treating neurological disorders.

A researcher from the University of Queensland has identified molecular doorways that could facilitate the delivery of drugs to the brain for treating neurological disorders.

Dr. Rosemary Cater from UQ’s Institute for Molecular Bioscience led a team that discovered that an essential nutrient called choline is transported into the brain by a protein called FLVCR2.

Marine Mystery Solved: Ancient Origins of Bioluminescence Uncovered

Posted by in category: education

Study explores an ancient lineage of marine invertebrates, including soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.

According to a new study by scientists from the Smithsonian’s National Museum of Natural History, bioluminescence originated in animals at least 540 million years ago among a group of marine invertebrates known as octocorals.

The results, published in the Proceedings of the Royal Society B, push back the previous record for the luminous trait’s oldest dated emergence in animals by nearly 300 million years, and could one day help scientists decode why the ability to produce light evolved in the first place.

Unlocking the Secrets of the Electron Universe: Scientists Discover Path Beyond Ohm’s Law

Posted by in categories: particle physics, quantum physics

Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the ‘electron universe,’ which describes the structure of electronic quantum states in a manner mathematically similar to the actual universe, within a magnetic material under ambient conditions.

The investigated geometric property – i.e., the quantum metric – was detected as an electric signal distinct from ordinary electrical conduction. This breakthrough reveals the fundamental quantum science of electrons and paves the way for designing innovative spintronic devices utilizing the unconventional conduction emerging from the quantum metric.

When Antibiotics Fail: MIT Scientists Use AI To Target “Sleeper” Bacteria

Posted by in categories: biotech/medical, health, robotics/AI

Most antibiotics target metabolically active bacteria, but with artificial intelligence, researchers can efficiently screen compounds that are lethal to dormant microbes.

Since the 1970s, modern antibiotic discovery has been experiencing a lull. Now the World Health Organization has declared the antimicrobial resistance crisis as one of the top 10 global public health threats.

When an infection is treated repeatedly, clinicians run the risk of bacteria becoming resistant to the antibiotics. But why would an infection return after proper antibiotic treatment? One well-documented possibility is that the bacteria are becoming metabolically inert, escaping detection of traditional antibiotics that only respond to metabolic activity. When the danger has passed, the bacteria return to life and the infection reappears.

“Tube Map” for Space: Unlocking Planetary Paths With Knot Theory

Posted by in categories: computing, mapping, mathematics, space

A novel mathematical technique from the University of Surrey now simplifies space mission planning by mapping efficient routes, akin to a subway map, potentially revolutionizing travel to the Moon and beyond.

Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste fuel.

The new method uses mathematics to reveal all possible routes from one orbit to another without guesswork or using enormous computer power.

Fusion Breakthrough: Compact New Device Reaches Temperatures of 37 Million Degrees

Posted by in categories: innovation, nuclear energy

In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy’s unique approach, known as a sheared-flow-stabilized Z pinch, has now joined those rarefied ranks, far exceeding this plasma temperature milestone in a device that is a fraction of the scale of other fusion systems.

A new research paper, published this month in Physical Review Letters, details measurements made on Zap Energy’s Fusion Z-pinch Experiment (FuZE) of 1–3 keV plasma electron temperatures — roughly the equivalent of 11 to 37 million degrees Celsius (20 to 66 million degrees Fahrenheit). Due to the electrons’ ability to rapidly cool a plasma, this feat is a key hurdle for fusion systems and FuZE is the simplest, smallest, and lowest cost device to have achieved it. Zap’s technology offers the potential for a much shorter and more practical path to a commercial product capable of producing abundant, on-demand, carbon-free energy to the globe.

“These are meticulous, unequivocal measurements, yet made on a device of incredibly modest scale by traditional fusion standards,” describes Ben Levitt, VP of R&D at Zap. “We’ve still got a lot of work ahead of us, but our performance to date has advanced to a point that we can now stand shoulder to shoulder with some of the world’s pre-eminent fusion devices, but with great efficiency, and at a fraction of the complexity and cost.”
