Capturing a cosmogenic isotope to determine the age of artifacts
You may probably wonder how archaeologists determine the age of ancient artifacts or how long a piece of rock exists above the surface. Isotopic dating can tell the age covering hundreds of thousands of years. For instance, common carbon isotope 14C.....»»
New nuclei can help shape our understanding of fundamental science on Earth and in the cosmos
In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams (FRIB) at Michigan State University has brought the stars closer to Earth......»»
Scientists discover "jumping genes" determine cabbage"s exterior
The genetic differences between pointed cabbage and cauliflower are greater than those between humans and chimpanzees. Nevertheless, they are considered the same species. Researchers from Wageningen and China mapped the extensive genetic variation of.....»»
Microplastics in soils: First consistent risk assessment
Microplastics in soil are extremely diverse and complex. This makes it difficult to determine the risks of plastic pollution to soil life, which is an increasing concern among policymakers and scientists. Researchers from the Spanish Institute IMDEA.....»»
How NASA uses simple technology to track lunar missions
NASA is using a simple but effective technology called Laser Retroreflective Arrays (LRAs) to determine the locations of lunar landers more accurately. They will be attached to most of the landers from United States companies as part of NASA's Commer.....»»
Scientists identify “universal network” of microbes for decomposing flesh
Findings could help forensic scientists better determine a body's precise time of death. Enlarge / It's tough to precisely determine cause of death in a corpse. Microbes found on decomposing flesh can help. (credit: Ralf Roletsch.....»»
Vanadium research makes key advance for capturing carbon from the air
A chemical element so visually striking it was named for a goddess shows a "Goldilocks" level of reactivity—neither too much nor too little—that makes it a strong candidate as a carbon scrubbing tool......»»
Waymo robotaxi attacked and set on fire in San Francisco
Investigators are trying to determine what prompted a crowd in San Francisco to attack a Waymo robotaxi in San Francisco on Saturday night......»»
Pioneering technique reveals new layer of human gene regulation
A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows......»»
Temperatures are rising, but soil is getting wetter—why?
Soil moisture can determine how quickly a wildfire spreads, how fast a hill turns into a mudslide, and perhaps most importantly, how productive our food systems are. As temperatures rise due to human-caused climate change, some researchers are concer.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
Astronomers measure the mass of the Milky Way by calculating how hard it is to escape
If you want to determine your mass, it's pretty easy. Just step on a scale and look at the number it gives you. That number tells you the gravitational pull of Earth upon you, so if you feel the number is too high, take comfort that Earth just finds.....»»

Researchers use supercomputer to determine whether "molecules of life" can be formed naturally in right conditions
Basic biology textbooks will tell you that all life on Earth is built from four types of molecules: proteins, carbohydrates, lipids, and nucleic acids. And each group is vital for every living organism......»»
Clownfish “count” white stripes to determine if an invader is friend or foe
They attacked similar fish with three stripes more often than those with one or two stripes. Enlarge / Clown anemonefish (Amphiprion ocellaris) seem to recognize different species of clownfish by counting white stripes. (credit:.....»»
A lead isotopic standard for instrument calibration
Stable isotope analysis is an important interdisciplinary tool used by numerous fields such as nuclear and homeland security, forensics, medicine and pharmaceuticals, human health and nutrition, and climate science. Achieving reliable metrology and t.....»»
A Trojan approach to guide and trap light beams via Lagrange points
Reliably guiding and capturing optical waves is central to the functioning of various contemporary technologies, including communication and information processing systems. The most conventional approach to guide light waves leverages the total inter.....»»
