Wild blacktip sharks can detect low-frequency sounds from nearly 250 feet away, according to experiments conducted off the Florida coast. The sharks not only heard the sounds but sharply changed direction away from…
Creatine helped middle-aged adults gain muscle and strength even without a structured workout program in a new 12-week study. When combined with exercise and a calorie-reduced diet, it produced even greater strength…
Scientists are developing a possible alternative to LASIK that reshapes the cornea without cutting it or using a laser. The technique uses a small electric potential and a specially shaped platinum lens to temporarily…
Depression may change which emotional faces children notice most, but the pattern appears to depend on family history. Children at higher familial risk became increasingly focused on sad faces, while lower-risk children…
Scientists have developed and experimentally demonstrated a long-sought method for identifying W states, an important form of multi-photon quantum entanglement. The technique could make complex entangled systems much…
A 245-million-year-old marine reptile fossil preserves an astonishing amount of detail, including its stomach, liver, and intestines. The discovery reveals that Austronaga minuta was highly adapted for swimming even…
Enceladus may naturally separate and concentrate chemicals from its hidden ocean as droplets slowly freeze and shatter on their way into space. The process could explain Cassini’s puzzling ice-grain chemistry while…
Scientists may have solved why the length of Earth’s day changes by a few milliseconds over decades. Subtle shifts in the inner core appear to tug on the mantle, revealing a surprisingly dynamic world thousands of…
CosmoCube will use the far side of the Moon as a shield from Earth’s radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could reveal how the cosmic…
Yellow-morph green sea turtles in the Galápagos surprised scientists by staying remarkably close to home instead of making the long journeys typically associated with sea turtles. Satellite tracking showed that none…
Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may drive the…
Scientists have discovered a new tick-borne virus in China that causes flu-like illness and may account for previously unexplained cases of fever, fatigue, digestive problems, and low platelet counts. Most patients with…
Covered by Phys.org, ScienceDaily. A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such observations in quantum…
People with diabetes reported better quality of life after days when their glucose stayed largely within a healthy range, even when levels fluctuated more than usual. The unexpected finding suggests that pursuing…
A new study suggests coffee may influence mood and brain function by changing the activity of microbes in the gut. Both caffeinated and decaf coffee were linked to lower stress, depression, and impulsivity, while also…
Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have…
A beautifully preserved fossil from Mongolia’s Gobi Desert has solved a mystery that puzzled paleontologists for nearly 40 years. Tamirkhan balcarceli shows that zhelestids were not early relatives of modern placental…
JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas disappears, giant…
A compound the body can make after eating pomegranates, walnuts, and some berries improved measures of heart function by up to 80% in animal models of a difficult-to-treat form of heart failure. Urolithin A helped stiff…
Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics…
