Catching Dark Matter in a Basement in Neutrino Alley

Posted by in categories: cosmology, particle physics

Scientists at Oak Ridge National Laboratory attempted to observe dark matter in a brightly-lit hallway in the basement using the sensitivity of their neutrino detectors. Neutrino Alley, where the team works, is located beneath the Spallation Neutron Source, a powerful particle accelerator. Following up on years of theoretical calculation, the COHERENT team set out to observe dark matter, which is believed to make up to 85% of the mass of the Universe. The experiment allowed the team to extend the worldwide search for dark matter in a new way, and they are planning to receive a much larger and more sensitive detector to improve their chances of catching dark matter particles.

Few things carry the same aura of mystery as dark matter. The name itself radiates secrecy, suggesting something hidden in the shadows of the Universe.

A collaborative team of scientists called COHERENT, including Kate Scholberg, Arts & Sciences Distinguished Professor of Physics, Phillip Barbeau, associate professor of Physics, and postdoctoral scholar Daniel Pershey, attempted to bring dark matter out of the shadows of the Universe and into a slightly less glamorous destination: a brightly lit, narrow hallway in a basement.

Fluid flow in the brain can be manipulated

Posted by in categories: biotech/medical, health, neuroscience

Researchers at Boston University, U.S. report that the flow of cerebrospinal fluid in the brain is linked to waking brain activity. Led by Stephanie Williams, and publishing in the open access journal PLOS Biology on March 30, the study demonstrates that manipulating blood flow in the brain with visual stimulation induces complementary fluid flow. The findings could impact treatment for conditions like Alzheimer’s disease, which have been associated with declines in cerebrospinal fluid flow.

Just as our kidneys help remove from our bodies, cerebrospinal fluid helps remove toxins from the brain, particularly while we sleep. Reduced flow of cerebrospinal fluid is known to be related to declines in brain health, such as occur in Alzheimer’s disease. Based on evidence from , the researchers hypothesized that while awake could also affect the flow of cerebrospinal fluid. They tested this hypothesis by simultaneously recording human brain activity via fMRI and the speed of cerebrospinal fluid flow while people were shown a checkered pattern that turned on and off.

Researchers first confirmed that the checkered pattern induced brain activity; blood oxygenation recorded by fMRI increased when the pattern was visible and decreased when it was turned off. Next, they found that the flow of cerebrospinal fluid negatively mirrored the blood signal, increasing when the checkered pattern was off. Further tests showed that changing how long the pattern was visible affected blood and fluid in a predictable way, and that the blood-cerebrospinal fluid link could not be accounted for by only breathing or heart rate rhythms.

Cancer mystery as cases rise among younger people around the world

Posted by in category: biotech/medical

The number of people under 50 with cancer is increasing in many countries and for many different tumour types. Why this is occurring isn’t entirely clear, but it may be due to some aspects of modern life.

Using artificial intelligence to design innovative materials

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

Advanced materials are urgently needed for everyday life, be it in high technology, mobility, infrastructure, green energy or medicine. However, traditional ways of discovering and exploring new materials encounter limits due to the complexity of chemical compositions, structures and targeted properties. Moreover, new materials should not only enable novel applications, but also include sustainable ways of producing, using and recycling them.

Researchers from the Max-Planck-Institut für Eisenforschung (MPIE) review the status of physics-based modelling and discuss how combining these approaches with artificial intelligence can open so far untapped spaces for the design of complex materials.

They published their perspective in the journal Nature Computational Science (“Accelerating the design of compositionally complex materials via physics-informed artificial intelligence”).

How a Laser Physics Induced Kerr-Newman Black Hole Can Release Gravitational Waves without Igniting the Black Hole Bomb (Explosion of a Mini Black Hole in a Laboratory)

Posted by in categories: cosmology, physics

In 2018, a team of scientists at the University of California, Santa Barbara proposed a method for creating Kerr-Newman black holes using lasers. However, this method has not yet been tested experimentally.

The team of scientists, led by Philip Gibbs, proposed to create Kerr-Newman black holes by colliding two high-energy laser beams. The collision would create a plasma that would be compressed and heated to extreme temperatures, creating a black hole.

Immortality Is Going To Happen, Scientist Reveals When We’ll Live Forever And It’s Not Far Away

Posted by in categories: biotech/medical, life extension, Ray Kurzweil

Futurist Ray Kurzweil is predicting that by 2030, microscopic gelbots in our bodies will make it possible to cure disease and live forever. You’re 40 years old, but you’re not Dwayne Johnson; it’s the time in life when your body doesn’t bounce back from a good workout as fast as it used to; when you eat a pizza, it sits with you for longer, and sleeping wrong could jumpstart a week of back pain.

Scientists have found major storage capacity in water-based batteries

Posted by in category: particle physics

Texas A&M University scientists have been working with metal-free, water-based battery electrodes, and they’re finding that the difference in energy storage capacity is as much as 1,000%.

In the scientists’ paper, published in Nature Materials this week, the water-based, or aqueous, batteries consist of a cathode – the negatively charged electrode; an anode – the positively charged electrode; and an electrolyte, like traditional batteries. But in this water-based battery, the cathodes and anodes are polymers that can store energy, and the electrolyte is water mixed with organic salts.

The electrolyte transfers the ions – the charge-carrying particles – back and forth between the cathode and the anode, and the electrolyte is also key to energy storage through its interactions with the electrode.
