Glowing corals that display a surprising array of colors have been discovered in the deep water reefs of the Red Sea.
The first species of yeti crab from hydrothermal vent systems of the East Scotia Ridge in the Southern Ocean, Antarctica, has been described. This Yeti Crab is famous for its body, which is densely covered by bristles -- known as setae -- and bacteria, giving it a fur-like appearance.
Astronomers have analyzed the clouds of gas and dust from some of the earliest galaxies ever observed -- one billion years after the Big Bang.
Telomeres, specialized ends of our chromosomes that dictate how long cells can continue to duplicate themselves, have long been studied for their links to the aging process and cancer. In an unexpected finding, researchers show how disabling telomere protection during cell division prompts cell death.
Sequencing the genome of Ebola virus strains circulating in Guinea has allowed scientists to retrace the spread of the virus and monitor its evolution in the country where the outbreak started. Characterization of the genetic variations of the virus is crucial to ensure the continued efficacy of diagnostic tools and for the development of effective treatments and vaccines.
A new analysis of one of the most bizarre-looking fossils ever discovered has definitively sorted its head from its tail, and turned up a previously unknown ring of teeth, which could help answer some of the questions around the early development of molting animals.
More than half of American children are dehydrated, and a researcher has found an easy way for children to gauge hydration using established protocols already in place for athletes. The research also shows that children can accurately self-assess hydration levels using established methods. Mild dehydration in children has been linked to reduced cognitive functioning and is associated with poorer school performance in children.
A writing intervention linked to improved academic performance among girls and minorities may work by triggering a sense of belonging, helping to ease the students' anxiety, say researchers. They are the first to apply text-mining techniques to analyze the content of experimental essays showing that some students do better in school when asked to write about values important to them.
Stem cells taken from donors are more likely to be more effective at battling diabetic retinopathy than cells taken from patients' own bodies, a new study concludes. The work is a critical step toward the goal of injecting stem cells into patients' eyes to stop or even reverse the vision loss. The findings also establish a crucial framework for evaluating stem cells to be used in potential future treatments for diabetic retinopathy.
Astronomers have discovered an immense cloud of hydrogen dispersing from a warm, Neptune-sized planet orbiting a nearby star. The enormous comet-like tail of the planet is about 50 times the size of the parent star.
A protein encoded by the gene glypican-1 (GPC1) present on cancer exosomes may be used as part of a potential non-invasive diagnostic and screening tool to detect early pancreatic cancer, potentially at a stage amenable to surgical treatment, according to a new study.
More Americans are using soft contact lenses—especially daily disposable lenses—and taking advantage of new designs targeting vision problems that were difficult to correct with previous contact lenses, reports a new article.
The notion that geography often shapes economic and political destiny has long informed the work of economists and political scholars. Now a study led by medical scientists reveals how geography also appears to affect the very survival of people with end-stage kidney disease in need of dialysis.
Researchers have made a crucial step toward nuclear spintronic technologies. They have gotten nuclear spins to line themselves up in a consistent, controllable way, and they have done it using a high-performance material that is practical, convenient, and inexpensive.
Researchers have, for the first time, uncovered the complex interdependence and orchestration of metabolic reactions, gene regulation, and environmental cues of clostridial metabolism, providing new insights for advanced biofuel development.
Researchers have designed a responsive hybrid material that is fueled by an oscillatory chemical reaction and can perform computations based on changes in the environment or movement, and potentially even respond to human vital signs.
In principle, antibiotics suppress infections either by killing the bacteria, which is called a bactericidal effect or by merely inhibiting their growth, by what is called a bacteriostatic effect. After the treatment has been stopped, growth-inhibited bacteria, however, can re-emerge from their dormancy to start multiplying again with latent infections relapsing back into full-blown attacks. A critical differentiator that separates the effects of bactericidal and bacteriostatic antibiotics has been identified by researchers: cellular respiration.
Active galactic nuclei are the brightest objects in the universe. They are not lit up permanently, but rather 'flicker' extremely slowly. This insight helps researchers better understand the influence these nuclei and black holes have on their host galaxy.
Medical students showed a greater acceptance of using approaches in genomic medicine, a key element in the practice of precision medicine, to treat patients as compared to physicians currently in practice according to a study.
The initial results of a study suggested that children born by Cesarean section were 21 percent more likely to be diagnosed with autism spectrum disorder but that association did not hold up in further analysis of sibling pairs, implying the initial association was not causal and was more likely due to unknown genetic or environmental factors.
