Phys.org / Drone captures narwhals using their tusks to explore, forage and play
The narwhal (Monodon monoceros), an iconic whale of remote Arctic waters, is widely known for its long, spiral tusk, which is really an elongated tooth. The tusk, which is predominantly found in males and can grow up to 10 ...
Phys.org / Why don't pandas eat more meat? Molecules found in bamboo may be behind their plant-based diet
Giant pandas have digestive systems that are typical for carnivores. Yet, bamboo is their main source of food. They have evolved several features; for example, pseudo thumbs to grasp bamboo and flat teeth that are well suited ...
Medical Xpress / Gene therapy developed for maple syrup urine disease shows promise
A study led by UMass Chan Medical School researchers has demonstrated that a gene therapy to correct a mutation that causes maple syrup urine disease (MSUD) prevented newborn death, normalized growth, restored coordinated ...
Phys.org / Scientists match Earth's ice age cycles with orbital shifts
Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests the onset of the next ...
Medical Xpress / Large population study identifies long-term health risks after COVID-19 hospitalization
A French nationwide study has revealed that survivors of COVID-19 hospitalization face an increased risk of death or organ-related disorders for up to two-and-a-half years after discharge.
Medical Xpress / Can a smartwatch save your life? Google researchers develop smartwatch algorithm to detect cardiac arrest
A machine learning algorithm running on a smartwatch demonstrated the ability to detect sudden loss of pulse with high specificity (99.99%) and moderate sensitivity (67.23%), according to a study led by Google Research. Designed ...
Phys.org / Hydrogen cyanide and acetylene detected in a brown dwarf atmosphere for the first time
Using the James Webb Space Telescope (JWST), an international team of astronomers has explored the atmosphere of a nearby brown dwarf binary designated WISE J045853.90+643451.9. As a result, they detected hydrogen cyanide ...
Phys.org / An equation of state for dense nuclear matter such as neutron stars
Neutron stars are some of the densest objects in the universe. They are the core of a collapsed megastar that went supernova, have a typical radius of 10 km—just slightly more than the altitude of Mt. Everest—and their ...
Phys.org / New study sets tighter constraints on elusive sterile neutrinos
Neutrinos have always been difficult to study because their small mass and neutral charge make them especially elusive. Scientists have made a lot of headway in the field and can now detect three flavors, or oscillation states, ...
Medical Xpress / Fat transport deficiency explains rare childhood metabolic crises
Researchers studying a protein linked to a rare, severe disease have made a discovery that sheds light on how cells meet their energy needs during a severe metabolic crisis. The findings could lead to new treatments for the ...
Phys.org / Super-resolution microscopy achieves nanometer resolution without traditional ON/OFF switching
Overcoming the resolution limit in a light microscope of around half a wavelength of light (about 250 nanometers) is one of the most significant developments in optics. Due to the wave nature of light, even the best lens ...
Phys.org / Contamination detection tool merges synthetic biology and nanotech for ultrasensitive water testing
A platform developed nearly 20 years ago previously used to detect protein interactions with DNA and conduct accurate COVID-19 testing has been repurposed to create a highly sensitive water contamination detection tool.
