Scientists have shown how the main psychoactive ingredient in cannabis, THC, could reduce tumor growth in cancer patients. Research reveals the existence of previously unknown signaling platforms that are responsible for the drug’s success in shrinking tumors.
In the movie “Terminator 2: Judgment Day,” the shape-shifting T-1000 robot morphs into a liquid state to squeeze through tight spaces or to repair itself when harmed. Now, a phase-changing material built from wax and foam, and capable of switching between hard and soft states, could allow even low-cost robots to perform the same feat.
Space weather impacts many modern-day technologies. But one of the most concerning– and least reported– space weather effects is the increased radiation exposure to passengers on commercial long-distance flights during so-called “solar radiation storms.”
Infants can tell the difference between sounds of all languages until about eight months of age when their brains start to focus only on the sounds they hear around them. It's been unclear how this transition occurs, but a study suggests that baby brains start laying down the groundwork of how to form words long before they actually begin to speak, and this may affect the developmental transition.
If you consider your friends family, you may be on to something. A study has found that friends who are not biologically related still resemble each other genetically. The study is a genome-wide analysis of nearly 1.5 million markers of gene variation.
Scientists have demonstrated for the first time a photonic router– a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.
Researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel, which could replace expensive and environmentally harmful fossil fuels. The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen.
Researchers are using new magnetic materials to develop revolutionary electrical motors and generators that promise significant energy savings. They have used the new motors to develop patented highly efficient water pump systems with potential widespread application.
Women are often encouraged to “eat for two” during pregnancy. While this is right in terms of eating to meet both Mom’s and the baby’s needs, it doesn’t mean doubling her total food and energy intake.
Researchers have invented a cheap, portable, microchip-based test for diagnosing type-1 diabetes that could speed up diagnosis and enable studies of how the disease develops. The test could improve patient care worldwide and help researchers better understand the disease.
An ancient token-based recording system from before the dawn of history was rendered obsolete by the birth of writing, according to popular wisdom. But now, latest excavations show that, in fact, these clay tokens were integral to administrative functions right across the Assyrian empire– millennia after this system was believed to have vanished.
A closer look based on micro-CT scans at a 100,000-year-old human skull that was recovered 35 years ago in China revealed that it had an inner ear formation that was thought only to have occurred in Neanderthals. In comparison, none of the three other archaic human skulls analyzed from different parts of China had this type of inner ear.
A third of Alzheimer’s disease cases worldwide can be attributed to risk factors that can be potentially modified, such as lack of education and physical inactivity. The estimate is lower than the previous estimate of one in two cases as it takes into account the fact that some of the risk factors used in previous studies are related.
Workers and scientists have carved a sprawling laboratory deep below Horonobe, a sleepy dairy town. Despite government reassurances, some of the town’s 2,500 residents fear the lab could turn their neighborhood into a nuclear waste storage site.
Unexplained rash? Check your iPad. It turns out the popular tablet computer may contain nickel, one of the most common allergy-inducing metals. Recent reports in medical journals detail nickel allergies from a variety of personal electronic devices, including laptops and cellphones. But it was an Apple iPad that caused an itchy body rash on an 11-year-old boy recently treated at a San Diego hospital.
