Scientists discover how mitochondria import antioxidants
Many of the processes that keep us alive also put us at risk. The energy-producing chemical reactions in our cells, for example, also produce free radicals—unstable molecules that steal electrons from other molecules. When generated in surplus, fre.....»»
New assessment suggests Anthropocene started in the 1950s
A team of Earth scientists from the Center for Marine Environmental Studies, the University of Tokyo, The Australian National University, Matsuyama University, Kyoto University, and Shimane University, has found, via a new assessment, that the 1950s.....»»

Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
Asteroid Ceres is a former ocean world that slowly formed into a giant, murky icy orb
Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimp.....»»
Scientists use drones to track white sharks along California beaches
The forecast at the beach today is cloudy, with a chance of sharks. At least, that's the forecast that researchers at UC Santa Barbara would like to be able to provide. They're leading a project to predict when and where great white sharks show up ne.....»»
Machine learning accelerates discovery of high-temperature alloys
In a study recently published in Engineering, scientists from the University of Science and Technology Beijing, Guangdong Ocean University, and AiMaterials Research LLC have demonstrated a novel method to accelerate the discovery of refractory high-e.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
Scientists identify structural basis of stitched-together protein complexes that recycle most proteins in cells
Scientists at Sanford Burnham Prebys have developed a clearer picture of how crucial machinery in the human cell's recycling process for obsolete and misshapen proteins—known as proteasomes—are formed......»»
Sloth survival under threat due to climate change, study finds
A new PeerJ study has revealed that sloths, the famously slow-moving creatures of Central and South America, may face existential threats due to climate change. The research, conducted by scientists studying the metabolic response of sloths to rising.....»»

These 3D-printed pipes inspired by shark intestines outperform Tesla valves
Prototypes control fluid flow in a preferred direction with no need for moving parts. Enlarge / Shark intestines are naturally occurring Tesla valves; scientists have figured out how to mimic their unique structure. (credit: Sara.....»»
Scientists uncover a critical component that helps killifish regenerate their fins
Spontaneous injuries like the loss of a limb or damage to the spinal cord are impossible for humans to repair. Yet, some animals have an extraordinary capacity to regenerate after injury, a response that requires a precise sequence of cellular events.....»»
Scientists create model of holographic dark energy that is no longer unstable
In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills up all of existing space-time but is impossible to.....»»
Model predicts 2024 tick cases in Australian pets
For the first time, University of Queensland scientists have been able to make a prediction about the severity of upcoming tick seasons to help vet surgeries and pet owners prepare......»»
Scientists develop method to control timing of synthetic DNA droplet division
Many cellular functions in the human body are controlled by biological droplets called liquid-liquid phase separation (LLPS) droplets. These droplets, made of soft biological materials, exist inside living cells but are not enclosed by membranes like.....»»
