A study published in Molecular Biology and Evolution found that non-African populations carry a piece of DNA from Neanderthals, indicating interbreeding between the two species. The genetic variation is present on the X chromosome and has been confirmed through independent analysis.
Researchers at Albert Einstein College of Medicine have developed a new fluorescent protein, iRFP, that allows for the non-invasive visualization of internal organs in live animals. The protein absorbs and emits light in the near-infrared spectrum, enabling clear imaging without radiation exposure or contrast agents.
KamLAND collaboration measures radioactive decay of uranium, thorium, and potassium in Earth's crust and mantle to estimate heat energy. The new estimate is precise enough to aid in refining accepted geophysical models, suggesting that radioactive decay supplies only about half the Earth's heat.
Researchers found that women who attended weekly group sessions to improve their body image lost more weight than those receiving general health information. The study showed a strong correlation between improved body image and positive changes in eating behavior, highlighting the importance of addressing body image issues in weight lo...
Scientists have developed a novel method to create ferroelectric nanostructures directly on flexible plastic substrates using thermochemical nanolithography and heated AFM tips. This breakthrough enables the production of complex structures for energy harvesting, sensors, and actuators at low temperatures.
The University of Sheffield has published an interactive version of The Acts and Monuments, a foundational source for the history of the English Reformation and late Medieval Church. The online edition provides scholars with a unique environment to access and understand the text, including searches, images, translations, and commentaries.
A study found that newer cardiac CT scanners deliver significantly less radiation than previous technology, allowing for non-invasive imaging of coronary arteries in young patients. The researchers used a combination of medication and new scanner technology to obtain excellent images without sedation or anesthesia.
Researchers have developed a platform technology for monitoring single-cell interactions in real-time using nanotechnology, allowing for unprecedented spatial and temporal resolution. This innovation has broad implications for basic science, drug discovery, and personalized medicine.
Scientists at Georgia Tech analyzed data from the March 11 Japan earthquake, finding that subsurface materials were weakened by as much as 70%, affecting how faults deliver movement to buildings and bridges. The study could improve building design and help predict effects of rare and extremely powerful events.
Researchers at NYU developed a compound that blocks signaling from a protein implicated in many types of cancer, including various developmental disorders and diseases. The compound disrupts the Sos-Ras interaction, which is crucial for stemming the production of cancer cells.
A new TB test, Xpert MTB/RIF, has been shown to be more sensitive and faster than conventional smear microscopy for diagnosing tuberculosis in children. The test detected twice as many cases among children under 15 and identified all confirmed TB cases in children with HIV.
