Research explores the cooling effects of 'scuba-diving' in lizards
Anoles are the scuba-diving champions of the lizard world, able to stay underwater for more than 16 minutes. For animals whose body temperature depends on the environment, time spent in a cool running stream can have some tradeoffs, according to new research.
Aluminum nanoparticles make tunable green catalysts
A nanotechnology pioneer has uncovered a transformative approach to harnessing the catalytic power of aluminum nanoparticles by annealing them in various gas atmospheres at high temperatures.
Tiny worms tolerate chornobyl radiation
A new study finds that exposure to chronic radiation from Chornobyl has not damaged the genomes of microscopic worms living there today -- which doesn't mean that the region is safe, the scientists caution, but suggests that these worms are exceptionally resilient.
Having self-control leads to power
Out-of-control behavior by CEOs and other powerful people constantly makes headlines -- so much so that some might consider impulsivity a pathway to power. New research finds that having self-control is often what leads to power.
Harmful 'forever chemicals' removed from water with new electrocatalysis method
Scientists have developed new electrochemical approaches to clean up pollution from 'forever chemicals' found in clothing, food packaging, firefighting foams, and a wide array of other products. A new study describes nanocatalysts developed to remediate per- and polyfluoroalkyl substances, known as PFAS.
For a healthy fruit snack, what would you choose?
Next time you're packing lunch for your kid or reaching for a healthy afternoon bite, consider this: only three types of packaged fruit snacks -- dried fruit, fruit puree and canned fruit with juice -- meet the latest recommendations for high-nutrition snacks set by federal dietary guidelines, according to food scientists.
A research team has identified materials capable of catalyzing the conversion of ortho-hydrogen to para-hydrogen. These catalysts should be essential to the spread of mass-transportation/storage of liquid hydrogen.
A smart molecule beats the mutation behind most pancreatic cancer
Researchers have designed a candidate drug that could help make pancreatic cancer, which is almost always fatal, a treatable, perhaps even curable, condition.
Using light to precisely control single-molecule devices
Researchers flip the switch at the nanoscale by applying light to induce bonding for single-molecule device switching.
Lab-grown liver organoid to speed up turtle research, making useful traits easier to harness
Researchers developed protocols for growing organoids that mimic a turtle liver, the first organoids developed for a turtle and only the second for any reptile. The discovery will aid deeper study of turtle genetics, including the cause of traits with potential medical applications for humans such as the ability to survive weeks without oxygen.
New method measures the 3D position of individual atoms
Since more than a decade it has been possible for physicists to accurately measure the location of individual atoms to a precision of smaller than one thousandth of a millimeter using a special type of microscope. However, this method has so far only provided the x and y coordinates. Information on the vertical position of the atom -- i.e., the distance between the atom and the microscope objective -- is lacking. A new method has now been developed that can determine all three spatial coordinates of an atom with one single image.
Toward understanding sperm quality
A novel screening system enables researchers to investigate sperm cell development and health at the molecular level. The new approach promises breakthroughs in male contraception and infertility treatments.
Researchers closing in on genetic treatments for hereditary lung disease, vision loss
Researchers who work with tiny drug carriers known as lipid nanoparticles have developed a new type of material capable of reaching the lungs and the eyes, an important step toward genetic therapy for hereditary conditions like cystic fibrosis and inherited vision loss.
