Where did life first form on Earth? Some scientists think it could have been around hydrothermal vents that may have existed at the bottom of the ocean 4.5 billion years ago. In a new paper in the journal Astrobiology, scientists at NASA’s Jet Propulsion Laboratory describe how they mimicked possible ancient undersea environments with a … Read more
A recent study led by USC Stem Cell scientist Janos Peti-Peterdi reveals that a loss of salt and body fluid can stimulate kidney regeneration and repair in mice. This groundbreaking research, published in the Journal of Clinical Investigation, uncovers an innate regenerative response driven by a small population of kidney cells known as the macula … Read more
The sweet smell of strawberries and other fruits is thanks to a chemical compound called ester, which is also found in many fats and polyesters. The ubiquitous compound can be broken down to produce desirable alcohols and other chemicals for use across industries, including pharmaceuticals and cosmetics, but the process can be costly, both financially … Read more
High-temperature fusion plasma experiments conducted in the Large Helical Device (LHD) of the National Institute for Fusion Science (NIFS), have renewed the world record for an acquired data amount, 0.92 terabytes (TB) per experiment, in February 2022, by using a full range of state-of-the-art plasma diagnostic devices. The International Thermonuclear Experimental Reactor (ITER), which is … Read more
Imagine you’re a student, it’s finals week, and you’re preparing for a big exam: do you pull an all-nighter or do you get some rest? As many a groggy-eyed person who’s stared blankly at a test knows, a lack of sleep can make it extraordinarily difficult to retain information. Two new studies from University of … Read more
Using NASA’s Chandra X-ray Observatory and ESA’s (European Space Agency’s) XMM-Newton, astronomers are exploring whether nearby stars could host habitable exoplanets, based on whether they emit radiation that could destroy potential conditions for life as we know it. This type of research will help guide observations with the next generation of telescopes aiming to take … Read more
The ability to adapt one’s beliefs about actions and their consequences in a constantly changing environment is a hallmark of advanced cognition. Disruptions to this ability can negatively impact cognition and behavior, potentially leading to states of mind such as paranoia, where there is a belief that others intend to cause harm. In a groundbreaking … Read more
In the deep-sea environment of the East Pacific Rise, where sunlight does not penetrate and the surroundings are known for their extreme temperatures, skull-crushing pressures, and toxic compounds, lives Riftia pachyptila, a giant hydrothermal vent tubeworm. Growing up to 6 feet tall with a deep-red plume, Riftia does not have a digestive system but thrives … Read more
Quantum computers have the potential to solve complex problems in human health, drug discovery, and artificial intelligence millions of times faster than some of the world’s fastest supercomputers. A network of quantum computers could advance these discoveries even faster. But before that can happen, the computer industry will need a reliable way to string together … Read more
Waves pick up information from their environment through which they propagate. A theory of information carried by waves has now been developed at TU Wien—with astonishing results that can be utilized for technical applications. Ultrasound is used to analyze the body, radar systems to study airspace or seismic waves to study the interior of our … Read more
One of the biggest challenges in quantum technology and quantum sensing is “noise”–seemingly random environmental disturbances that can disrupt the delicate quantum states of qubits, the fundamental units of quantum information. Looking deeper at this issue, JILA Associate Fellow and University of Colorado Boulder Physics Assistant Professor Shuo Sun collaborated with Andrés Montoya-Castillo, Assistant Professor … Read more
Vortices are a common physical phenomenon. You find them in the structure of galaxies, tornadoes and hurricanes, as well as in a cup of tea, or water as it drains from the bathtub. Normally, vortices are formed when very fast-flowing air, water or another substance encounters an area with a slower flow. They are characterized … Read more
From ancient texts we know that—for their times—the ancient Egyptians were exceptionally skilled at medicine. For example, they could identify, describe, and treat diseases and traumatic injuries, build protheses, and put in dental fillings. Other conditions, like cancer, they couldn’t treat—but they might have tried. Examining the limits of traumatological and oncological treatments in ancient … Read more
Archaeologists have discovered evidence for the earliest cattle herds in northern Europe, at the site of Swifterbant in the Netherlands. Using a combination of zoological, botanical, and biochemical methods, they investigated the emergence of farming in northern Europe and found that, not only are these the earliest known domestic cattle, they were also managed in … Read more
Scientists have studied puddle frogs to identify genetic variation hotspots and places where the climate crisis could wipe out populations too homogenous to adapt. Even widespread species could be genomically vulnerable to the climate crisis, scientists warn. By studying the DNA of puddle frogs living in central African rainforests, the scientists found that areas of … Read more
A distinctive plant that steals nutrients from underground fungi has been identified as a new species by botanists from the Forest Research Institute Malaysia (FRIM), working alongside local naturalists and stakeholders. The findings were recently published in the journal PhytoKeys. Discovery and classification Discovered in the tropical rainforests of Peninsular Malaysia, the plant, named Thismia … Read more
A simple concept of decay and fission of “magnetic quivers” helps to clarify complex quantum physics and mathematical structures. An international research team led by Marcus Sperling, a project leader at the Faculty of Physics, University of Vienna, has sparked interest in the scientific community with pioneering results in quantum physics. In their current study, … Read more
Researchers at UC Riverside have unveiled a groundbreaking approach to controlling termite infestations that is both highly effective and environmentally friendly. This new method leverages a naturally occurring chemical to lure termites to their demise, offering a promising alternative to traditional pest control strategies. The research, published in the Journal of Economic Entomology, centers around … Read more
Joint research led by Michiko Fujii of the University of Tokyo has unveiled a possible formation mechanism for intermediate-mass black holes (IMBHs) in globular clusters. These clusters, which can contain tens of thousands to millions of tightly packed stars, have long been suspected to host IMBHs, but direct theoretical evidence has been lacking until now. … Read more
Quantum computers hold the promise of solving extremely complex problems rapidly—tasks that could take the world’s most powerful supercomputers decades to crack. However, achieving such performance requires building a system with millions of interconnected qubits. The creation and control of such vast numbers of qubits in a hardware architecture is a formidable challenge that scientists … Read more
