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.....»»
Reevaluation puts mid-Proterozoic oxygen levels higher than previously reported
Oxygen levels in the atmosphere during the mid-Proterozoic—about 1.4 billion years ago—were higher than previously thought, according to an international team of researchers who looked at oxygen combined with sulfur to determine that previous num.....»»
Hundreds of gene regulatory motifs cooperate and conflict to make brain cells
DNA is considered the blueprint of our human bodies. It codes for the tens of thousands of genes that determine whether a cell transforms into a brain cell, heart cell or even cancer cell. Other DNA sequences, known as enhancers, determine if genes a.....»»
This is why boa constrictors can still breathe while squeezing the life out of prey
Snakes activate different sections of the rib cage, using far end of lungs as a bellows. Enlarge / Brown University biologists X-rayed boa constrictors to determine how they manage to breathe while squeezing prey to death. (credit: Jo.....»»

Scientists determine structure of a DNA damage "first responder"
DNA is often likened to a blueprint. The particular sequence of As, Cs, Gs, and Ts in DNA provides information for building an organism......»»
Hubble used two instruments to image this beautiful galaxy
This week's image from the Hubble Space Telescope is a stunner: The beautiful galaxy NCG 1097, as capturing using two of Hubble's instruments......»»
New method of bond detection could lead to cheaper, more efficient ways to capture carbon
University of Colorado Boulder researchers have developed a new tool that could lead to more efficient and cheaper technologies for capturing heat-trapping gases from the atmosphere and converting them into beneficial substances, like fuel or buildin.....»»
Cornell Researchers Taught a Robot To Take Airbnb Photos
A team of researchers from Cornell University used a computational aesthetic system to teach an AI robot "to not only determine the most pleasing picture in a given dataset, but capture new, original -- and most importantly, good -- shots on its own,.....»»
Smaller, ground-based telescopes can study exoplanet atmospheres, too
The next step to understanding exoplanets is to understand their atmospheres better. Astronomers can determine a planet's mass, density, and other physical characteristics fairly routinely. But characterizing their atmospheres is more complicated......»»
The Best Waterproof Camera
Capturing your favorite moments outdoors is all the better with a waterproof camera. Not only are they great for taking pictures underwater, but they're also perfect for capturing fun action shots above ground. These cameras are made with durable.....»»
"The Andy Warhol Diaries" review: Capturing a complicated queer icon
You don't need to know about pop art to know the work of Andy Warhol. The Pittsburgh-born artist, who rose to fame with his silkscreen paintings Campbell's Soup Cans, was so influential that his unique and multifaceted brand has gone on to influence.....»»
Chemical engineers use neural networks to discover the properties of metal-organic frameworks
Metal-organic frameworks, a class of materials with porous molecular structures, have a variety of possible applications, such as capturing harmful gases and catalyzing chemical reactions. Made of metal atoms linked by organic molecules, they can be.....»»
Converting plastic waste into porous carbon for capturing carbon dioxide
Besides climate change, which is mostly the result of our carbon dioxide (CO2) emissions, plastic pollution stands as one of the most critical environmental concerns of this decade. The sheer quantity of discarded and misplaced plastic is dealing irr.....»»
From quantum vibrations to nanodiamonds, unusual toolbox puts dangerous SARS-CoV-2 variants under surveillance
With each new SARS-CoV-2 variant that has emerged, global panic ensues to determine its level of threat. But a group of quantum biologists, engineers, and virus physicists think we already have the tools to more easily detect—and stop—dangerous c.....»»
Every second counts in Jaguar Racing Formula E
Races can be won or lost with fractions of seconds separating first, second, and third. Many factors determine who stands on the podium, awarded with points and champagne, and who returns to the pit on a recovery truck. One factor that plays a critic.....»»
A few simple rules determine how floating fire ant rafts change shape over time

SEC Scrutinizes NFT Market Over Illegal Crypto Token Offerings
The U.S. Securities and Exchange Commission is scrutinizing creators of NFTs and the crypto exchanges where they trade to determine if some of the assets run afoul of the agency's rules, Bloomberg News reported Thursday, citing people familiar with t.....»»
Capturing the many facets of evolvability
All life evolves: microorganisms can become resistant to drugs, viruses evade our vaccines, and species may adapt to climate change. Even the ability to evolve can evolve. If we were to understand how this happens and which mechanisms play a role, it.....»»
