The heart drug digoxin could potentially be combined with existing cancer therapies to prevent the spread of tumors, an early trial suggests. But questions remain.
SPACE (KXAN) — A star flying through the night sky may be the fastest-moving solar system in our galaxy. Possibly a planet a little larger than Neptune orbiting a small star, the system could be moving at least 1.2 million miles per hour, according to NASA.
First discovered in 2011, the system was included in a research project led by Sean Terry with the University of Maryland, College Park, and NASA’s Goddard Space Flight Center. Terry’s paper on the star was published in February in The Astronomical Journal.
“We think this is a so-called super-Neptune world orbiting a low-mass star at a distance that would lie between the orbits of Venus and Earth if it were in our solar system,” Terry said in a press release from NASA.
Researchers in Sweden have reported control over a new kind of magnetism with the potential to boost electronic performance. Their work shows that this new class of magnetism, called altermagnetism, can increase memory device operation speeds by up to a thousand times.
Scientists say it stands apart from the two widely known forms of magnetic order and may open doors to faster, more efficient technologies.
Scientists from the University of Nottingham’s School of Physics and Astronomy have confirmed this third category in microscopic devices, and their findings have been published in Nature. Professor Peter Wadley from the same institution led the research.
Qubits—the building blocks of quantum computing—are driving advancements across the tech industry. Among them, superconducting qubits hold great promise for large-scale quantum computers. However, they rely on electrical signals, making them challenging to scale.
In a breakthrough, physicists at the Institute of Science and Technology Austria (ISTA) have successfully developed a fully optical readout for superconducting qubits, overcoming a key technological hurdle. Their findings, recently published in Nature Physics.
<em>Nature Physics</em> is a prestigious, peer-reviewed scientific journal that publishes high-quality research across all areas of physics. Launched in 2005, it is part of the Nature family of journals, known for their significant impact on the scientific community. The journal covers a wide range of topics, including fundamental physics, applied physics, and interdisciplinary research that bridges physics with other scientific disciplines. Nature Physics aims to highlight the most impactful and cutting-edge research in the field, providing insights into theoretical, experimental, and applied physics. The journal also features reviews, news, and commentary on major advances and issues affecting the physics community.
Scientists at the University of Oxford have harnessed the ability of quantum teleportation for the first time, hoping to scale the idea with supercomputers.
Proteins’ amino-acid sequences appear to guide their access to blob-like aggregates involved in many cell processes.
Caption: “I really like to do research because every day you have a hypothesis, you have a design, and you make it happen,” says MIT Associate Professor Xiao Wang.
Hundreds of quantum computing firms around the world are racing to commercialise these once-exotic devices, but the jury is still out on who is going to pull ahead and produce a machine that actually does something useful.
Mitochondria are well known as the powerhouses of the cell. These crucial, energy generating organelles even have their own little genomes, and make their own proteins. Mutations in mitochondrial DNA (mtDNA) can cause some serious diseases, and dysfunctional mitochondria have been associated with a wide variety of health disorders. Researchers have also found links between mitochondrial defects and diabetes.
There are special cells in the pancreas known as beta cells, which is where insulin is generated. When these cells are lost due to an autoimmune attack, type 1 diabetes arises. Some studies have determined that there are abnormal mitochondria in the beta cells of some diabetes patients.
