Machines mimicking a human's sense of taste are going on a beer-tasting binge. Despite being called electronic tongues, these devices aren't party robots, pouring beer onto wagging, mechanical tongues— they accurately distinguished between four styles of lager beer 100 percent of the time.
With the help of a computer program called "Rosetta," researchers have "redesigned" an antibody that has increased potency and can neutralize more strains of the AIDS-causing human immunodeficiency virus (HIV) than can any known natural antibody. The find suggests that computer-redesigned antibodies may speed the search for an effective therapy or vaccine for a virus that so far has eluded all attempts to eradicate it.
A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers have found. They showed that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder.
Even though much of the population in developing countries is involved in agriculture, food security is virtually out of reach. Often the only resort is to purchase a cow, buffalo or sheep to provide a steady supply of fresh milk, a nutritious staple of a daily diet. But how to preserve it safely? Research has found that short pulsed electric fields can be used to kill milk-contaminating bacteria.
Radio systems, such as cell phones, have become an integral part of modern life. However, today’s devices use twice as much of the radio spectrum than necessary. New technology could fundamentally change radio design and increase data rates and network capacity, reduce power consumption, create cheaper devices and enable global roaming.
It’s no wonder that giant pandas are always chewing and eating: their gut bacteria are not the type for efficiently digesting bamboo. The bamboo-eating giant panda actually harbors a carnivore-like gut microbiota predominated by bacteria such as Escherichia/Shigella and Streptococcus.
German Chancellor Angela Merkel and French President Francois Hollande confirmed their commitment to fighting global warning Tuesday, gathering with others in Berlin to prepare for this year's UN Climate Change Conference.
The federal government hopes to reverse America's declining honeybee and monarch butterfly populations by making more federal land bee-friendly, spending more money on research and considering the use of less pesticides.
Four sham cancer charities were charged with bilking more than $187 million from consumers by telling donors the funds would help cancer patients, including children– but then pocketed the money, federal authorities announced.
Kimberly-Clark Spring Green and Kimberly-Clark Forest Green Nitrile Exam Gloves deliver a range of benefits, including enhanced dexterity, strong wet and dry grip and a way to reduce lab waste.
INTEGRA has expanded its VIAFLO II electronic pipette range to include 50 uL models.
The Motum TS Spray System from Empire Laboratory Automation Systems provides a compact, easy-to-use benchtop device for spraying coatings onto substrates of any type.
In the 14th century, Europe was devastated by the Black Death, a scourge spread by rodent populations. Now, a group of 21st century researchers are trying to forecast where rats and mice and other critters are most likely to spread viruses, bacteria, fungi and other illnesses communicable to humans.
Dead satellites adrift, rocket fragments and shards of tools orbit the planet. The International Space Station has to take evasive action and constantly be on guard for incoming projectiles. But a laser on one of the space station’s modules could shoot the space junk, slowing it enough so that it falls out of orbit.
Biologists have long puzzled about how evolutionary selection, known for its ruthless requirement for efficiency, allows the existence of males— when in so many species their only contribution to reproduction are spermatozoa. Now, research has found, when males compete and females choose over reproduction, it improves population health and protects against extinction, even in the face of genetic stress from high levels of inbreeding.
