Phys.org / New technique lights up where drugs go in the body, cell by cell
When you take a drug, where in your body does it actually go? For most medications, scientists can make only educated guesses about the answer to this question. Traditional methods can measure the concentration of a drug ...
Phys.org / Pahon Cave provides a look into 5,000 years of surprisingly stable Stone Age tool use
The Pahon Cave in Gabon offers archaeologists a well-preserved look into the Late Stone Age time period in central Africa, thanks to the stratified layers of guano-based sediment. This is in contrast with much of the surrounding ...
Phys.org / What is quantum in quantum thermodynamics?
(Phys.org)—A lot of attention has been given to the differences between the quantum and classical worlds. For example, quantum entanglement, superposition, and teleportation are purely quantum phenomena with no classical ...
Phys.org / Magnetically controlled battery could store energy for power grids
(Phys.org)—Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, ...
Phys.org / A universal law could explain how large trades change stock prices
Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?
Tech Xplore / New computer vision method links photos to floor plans with pixel-level accuracy
For people, matching what they see on the ground to a map is second nature. For computers, it has been a major challenge. A Cornell research team has introduced a new method that helps machines make these connections—an ...
Medical Xpress / Foods with healthy-sounding buzzwords could be hiding added sugar in plain sight
Many consumers feel pride in avoiding the glazed pastries in the supermarket and instead opting for "all natural" granola that comes packed with extra protein. Same goes for low-fat yogurts "made with real fruit," organic ...
Phys.org / 8.2 ka event triggered social transformation, not destruction, at China's Jiahu site
In a recent study, Dr. Yunchen Tan and colleagues examined the response of the North China Plain settlement of Jiahu to the abrupt climatic 8.2 ka event. They found that Jiahu not only survived but also demonstrated remarkable ...
Phys.org / Molecular mechanisms behind speciation in corals identified
Matías Gómez-Corrales, a recent biological sciences Ph.D. graduate from the University of Rhode Island, and his advisor, Associate Professor Carlos Prada, have published a paper in Nature Communications, revealing key mechanisms ...
Phys.org / Artificial metabolism turns waste CO₂ into useful chemicals
In a breakthrough that defies nature, Northwestern University and Stanford University synthetic biologists have created a new artificial metabolism that transforms waste carbon dioxide (CO2) into useful biological building ...
Phys.org / PFAS concentrations can double with every step up the food chain
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
Phys.org / Astronomers find planetary and stellar companions to two ultracool dwarfs in Taurus
Astronomers from the University of Hawai'i (UH) at Manoa and elsewhere have observed the Taurus star-forming region, which resulted in the discovery of planetary-mass and stellar companions of two ultracool dwarf stars. The ...
