Monitoring Europe’s vast nature protection areas used to be extremely difficult. Thanks to computer algorithms, this can now be done using aircraft and laser technology.
Neanderthals from the French region of Poitou-Charentes cut, beat and fractured the bones of their recently deceased companions, as revealed by the fossil remains of two adults and a child found at the Marillac site. These manipulations have been observed at other Neanderthal sites, but scientists still do not know whether they did this for cannibalism or ceremony.
Citrus fruits are among the most important commercially cultivated fruit trees in the world, yet little is known of the origin of the citrus species and the history of its domestication. Now, researchers have performed the largest and most detailed genomic analysis on 30 species of Citrus— representing 34 citrus genotypes— and used chloroplast genomic data to reconstruct its evolutionary history.
Astronomers believe they might have observed the first potential signs of dark matter interacting with a force other than gravity. They saw a dark matter clump that appeared to be lagging behind the galaxy it surrounds. Such an offset is predicted during collisions if dark matter interacts, even very slightly, with forces other than gravity.
George Harrison Shull, born April 15, 1874, was an American plant geneticist. Shull began his career, after obtaining a doctorate from the Univ. of Chicago, as a botanical investigator at the Carnegie Institution at the Station for Experimental Evolution, Cold Spring Harbor, NY. There, he completed research that would distinguish him as the father of hybrid corn.
As heat sources go in the academic science laboratory, the alcohol lamp has remained the old standby for many years. Unfortunately, this inexpensive heat source has been involved in a continuous series of laboratory accidents, many of which have been quite serious.
The environment of the womb, which is determined by a mother's health, lifestyle and surroundings, can alter the development of a fetus with permanent and lifelong implications. We've long known that a pregnant mother's alcohol and tobacco use can harm a developing fetus but, now, researchers are learning much more about how a baby's first nine months before birth can affect its health into adulthood.
Composite materials used in aircraft wings and fuselages are typically manufactured in large, industrial-sized ovens: multiple polymer layers are blasted with temperatures up to 750 F, and solidified to form a resilient material. Now, aerospace engineers have developed a carbon nanotube film that can heat and solidify a composite without the need for massive ovens.
Fisheries managers have decided to call off the West Coast sardine fishing season that starts in July because of rapidly dwindling numbers, hoping to save an iconic industry from the kind of collapse that hit in the 1940s and lasted 50 years.
There has long been interest in using genetically engineered microbes to target and destroy cells within solid tumors. Now, a study has demonstrated that genetically modified Salmonella can be used to kill cancer cells.
A natural compound derived from the bark of the magnolia tree, can protect a mouse's heart from hypertrophy, a thickening of cardiac muscle often caused by chronic high blood pressure that can lead to heart failure.
Scientists have found a key ingredient in aspirin and anti-pimple products, salicylic acid, is a cost-effective plant growth and survival improver during a world-first desert restoration trial in Saudi Arabia.
Researchers seeking better efficiency for cars quickly determined that cooling in direct proximity to the body provided the most efficient alternative to normal air conditioning. In contrast to previously deployed solutions, in which the entire interior is cooled or heated to the same temperature, heat is generated or dissipated only where it can actually be felt by the passengers.
Motic has designed a tilt-and-swivel C-mount for iPads and tablets so they fit directly onto an optical microscope, magically converting them into a dynamic imaging station that will preview, acquire, store, measure and communicate microscope images.
Malvern Instruments has launched two new-generation isothermal titration calorimeters (ITC), advancing its recently acquired MicroCal range to further support life science researchers studying biomolecular interactions.
