In the 1998 Hollywood blockbuster "Armageddon," Bruce Willis and Ben Affleck race to save the Earth from being pulverized by an asteroid.
NGC 2438 is a planetary nebula, formed after the death of a Sun-like star. The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core. A halo of glowing gas over 4.5 light-years across surrounds the nebula's brighter inner ring. Many round or nearly round planetary nebulae display these halo structures, and astronomers have been...
It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers of Karlsruhe Institute of Technology (KIT), Friedrich-Alexander-Universität Erlangen-Nuremberg (FAU), and Max Planck Center for Physics and Medicine (MPZPM) have now found that the formation of...
Lawrence Livermore National Laboratory (LLNL) scientists have found that atomic disorder in certain boron-based hydrogen storage systems can potentially improve the rate of hydrogen uptake.
Water plays several important roles within the human body, even affecting the DNA in our cells. The entire surface of a DNA double helix is coated in layers of water molecules. This sheath of water attaches to the genetic material through hydrogen bonds, made by sharing hydrogen atoms between molecules. Through hydrogen bonds, water can influence how DNA takes shape and interacts with other...
NASA's Cooperative Autonomous Distributed Robotic Exploration (CADRE) project is developing small robots programmed to work autonomously as a team to explore the lunar surface.
Researchers have identified several metabolites in the blood whose levels are altered by coffee consumption. Levels of 3 of these coffee-related metabolites were significantly associated with individuals' risk of developing chronic kidney disease.
Blocking a molecule that draws sensory nerves into musculoskeletal injuries prevents heterotopic ossification (HO), a process in which bone abnormally grows in soft tissue during healing, researchers reported. The findings suggest that drugs currently being tested in clinical trials to inhibit this molecule for pain relief could also protect against this challenging condition.
Theorists have observed a rare phenomenon called the quantum anomalous Hall effect in a very simple material. Previous experiments have detected it only in complex or delicate materials.
Researchers have developed a method to validate test drives through highly realistic driving simulation studies and to substantially simplify the approval process for automated driving systems.
