Ceramides found to be key in aging muscle health
Posted by Genevieve Klien in categories: biotech/medical, life extension
During aging, mice, like humans, become inactive and lose muscle mass and strength. A team of scientists led by Johan Auwerx at EPFL have now discovered that when mice age, their muscles become packed with ceramides. Ceramides, known for their use in skin care products, are sphingolipids, a class of fat molecules that are not used to produce energy but rather perform different tasks in the cell.
The researchers found that, in aging, there is an overload of the protein SPT and others, all of which are needed to convert fatty acids and amino acids to ceramides. “The sphingolipids and ceramides are complex yet very interesting fat class, and there is high potential to further study their role in aging, as they perform many diverse functions,” says Dr. Pirkka-Pekka Laurila, a medical doctor and the lead author of the study.
Next, the scientists wanted to see whether reducing ceramide overload could prevent age-related decline in muscle function. They treated old mice with ceramide blockers, such as myriocin and the synthetic blocker Takeda-2, and used adeno-associated viruses to block ceramide synthesis specifically in muscle. The ceramide blockers prevented loss of muscle mass during aging, made the mice stronger, and allowed them to run longer distances while improving their coordination.

Using quantum-inspired computing to discover an improved catalyst for clean hydrogen
Posted by Genevieve Klien in categories: computing, engineering, quantum physics, sustainability
Researchers from the University of Toronto’s Faculty of Applied Science & Engineering and Fujitsu have developed a new way of searching through ‘chemical space’ for materials with desirable properties.
The technique has resulted in a promising new catalyst material that could help lower the cost of producing clean hydrogen.
The discovery represents an important step toward more sustainable ways of storing energy, including from renewable but intermittent sources, such as solar and wind power.

SpaceX launches NASA satellite to study world’s water, sticks rocket landing
Posted by Eamon Everall in category: satellites
The first satellite specifically designed to conduct a global survey of Earth’s surface water has taken to the skies.
A SpaceX Falcon 9 rocket launched the Surface Water and Ocean Topography (SWOT) satellite before dawn on Wednesday (Dec. 16) from Space Launch Complex-4E at Vandenberg Space Force Base in California.

Scientists delighted as failure to detect key signal from space explains the beginnings of the universe
Posted by Paul Battista in category: space
Scientists have failed to detect a key signal from space – and used it to explain some of the earliest parts of the universe.
The inability to pick up the signal has allowed researchers to better understand the first galaxies to exist. It is one of the first times they have been able to study the period known as the “cosmic dawn”, when the first stars and galaxies came into being.
Scientists are now able to place limits on the mass and energy coming out of those first stars and galaxies – using a counterintuitive method.

Diabetes: Insulin-mimicking molecule could be developed into oral pill
Posted by Genevieve Klien in category: biotech/medical
A recent study identified a non-insulin-related protein that can activate the human insulin receptor, which could lead to the development of an insulin-mimicking oral pill and replace the need for daily injections to treat diabetes.

‘Game changer’ satellite will measure most of the water on the planet
Posted by Genevieve Klien in category: satellites
The first mission to survey nearly all of the water on Earth’s surface has launched.
The international Surface Water and Ocean Topography mission, known as SWOT, lifted off aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California at 6:46 a.m. ET on Friday. The first stage of the rocket successfully landed back on Earth at 6:54 a.m. ET.
Live coverage began on NASA’s website at 6 a.m. ET.

Imposter physical particles revealed: A key advance for quantum technology
Posted by Paul Battista in categories: computing, particle physics, quantum physics, space
The most common particles are electrons and photons, which are understood to be examples from the great families of fermions and bosons, to which all other particles in nature belong. But there is another possible category of particles, the so-called anyons. Anyons are predicted to arise inside materials small enough to confine the electronic state wave function, as they emerge from the collective dance of many interacting electrons.
One of these is named Majorana zero mode, anyonic cousins to the Majorana fermions proposed by Ettore Majorana in 1937. Majoranas, as these hypothetical anyons are affectionally called, are predicted to exhibit numerous exotic properties, such as simultaneously behaving like a particle and antiparticle, allowing mutual annihilation, and the capability to hide quantum information by encoding it nonlocally in space. The latter property specifically holds the promise of resilient quantum computing.
Since 2010, many research groups have raced to find Majoranas. Unlike fundamental particles, such as the electron or the photon, which naturally exist in a vacuum, Majorana anyons need to be created inside hybrid materials. One of the most promising platforms for realizing them is based on hybrid superconductor-semiconductor nanodevices. Over the past decade, these devices have been studied with excruciating detail, with the hope of unambiguously proving the existence of Majoranas. However, Majoranas are tricky entities, easily overlooked or mistaken with other quantum states.
