| Dinosaur fossils from China help researchers describe new 'Titan' Posted: 29 Jan 2014 03:48 PM PST Paleontologists have characterized a new dinosaur based on fossil remains found in northwestern China. The species, a plant-eating sauropod named Yongjinglong datangi, roamed during the Early Cretaceous period, more than 100 million years ago. This sauropod belonged to a group known as Titanosauria, members of which were among the largest living creatures to ever walk the earth. |
| Sea level variations escalating along eastern Gulf of Mexico coast Posted: 29 Jan 2014 01:55 PM PST Around the globe, sea levels typically rise a little in summer and fall again in winter. Now, a new study shows that, from the Florida Keys to southern Alabama, those fluctuations have been intensifying over the past 20 years. |
| Posted: 29 Jan 2014 11:56 AM PST In the dangerous waters of an ancient oxbow lake created by a flooded and unnamed meandering river, the female phytosaur died and sank to the bottom 205 million years ago. About 40 yards away the remains of a larger male also came to rest, and both disappeared in a tomb of soil and sediment. Evidence for the cause of their deaths and the rest of their bodies have vanished with time, but their skulls remained. After careful research, a paleontologist says he and others have discovered a new species of the Triassic-age monster in the wilds of West Texas. |
| Researchers trace path of bat killer: White Nose Syndrome Posted: 29 Jan 2014 10:51 AM PST As North American bats face a death toll approaching 7 million, scientists reveal new clues about their killer, White Nose Syndrome, or WNS. The researchers reveal that the deadly WNS fungus can likely survive in caves with or without the presence of bats and threatens the regional extinction of North American bats. |
| Modeling buildings by the millions: Building codes in China tested for energy savings Posted: 29 Jan 2014 10:50 AM PST China can build its way to a more energy efficient future -- one house, apartment and retail store at a time -- by improving the rules regulating these structures, according to a new study. Scientists have created a unique model that projects how much energy can be saved with changes to China's building energy codes. |
| Blood test developed for devastating disease of boas, pythons Posted: 29 Jan 2014 10:50 AM PST Researchers have developed a simple immune-based screening test to identify the presence of a debilitating and usually fatal disease that strikes boas and pythons in captivity as well as those sold to the pet trade worldwide. |
| Unknown aquatic sponge bacteria, a chemical factory Posted: 29 Jan 2014 10:50 AM PST A new, unknown strain of bacteria produces most of the bioactive substances that the stony sponge Theonella swinhoei exudes. An international research team describes these natural products, the associated genes and strain of bacteria in a new publication. |
| Neanderthal lineages excavated from modern human genomes Posted: 29 Jan 2014 10:49 AM PST A substantial fraction of the Neanderthal genome persists in modern human populations. A new approach for analyzing whole-genome sequencing data from 665 people from Europe and East Asia shows that more than 20 percent of the Neanderthal genome survives in the DNA of this contemporary group. Significant amounts of population-level DNA sequences might be obtained from extinct groups even in the absence of fossilized remains, because these archaic sequences might have been inherited by other individuals from whom scientists can gather genomic data. |
| Posted: 29 Jan 2014 10:49 AM PST Remnants of Neanderthal DNA in modern humans are associated with genes affecting type 2 diabetes, Crohn's disease, lupus, biliary cirrhosis and smoking behavior. They also concentrate in genes that influence skin and hair characteristics. At the same time, Neanderthal DNA is conspicuously low in regions of the X chromosome and testes-specific genes. |
| Posted: 29 Jan 2014 08:52 AM PST Researchers have developed a new computer algorithm that predicts which metabolic genes are lethal to cells when overproduced. Their findings could help guide metabolic engineering to produce new chemicals and drugs in more cost-effective ways. |
| Single gene separates queen from workers Posted: 29 Jan 2014 08:51 AM PST Scientists have identified how a single gene in honey bees separates the queens from the workers. A team of scientists unraveled the gene's inner workings. The gene, which is responsible for leg and wing development, plays a crucial role in the evolution of bees' ability to carry pollen. |
| Posted: 29 Jan 2014 08:49 AM PST A new study has uncovered a previously unknown magma chamber deep below the most active volcano in the world -- Kilauea. This is the first geophysical observation that large magma chambers exist in the deeper parts of the volcano system. |
| Posted: 29 Jan 2014 08:45 AM PST Scientists have successfully taken inspiration from the mechanics of natural structures like seashells in order to significantly increase the toughness of glass. |
| Warmer winters may be pushing raptors northward Posted: 29 Jan 2014 08:44 AM PST Research shows that several raptor species appear to be responding to warmer winters by shortening their annual migration by as much as seven or eight kilometers (four to five miles) per year. |
| Designer proteins provide new information about body's signal processes Posted: 29 Jan 2014 04:59 AM PST Researchers can radically alter the properties of proteins by redesigning their chemical structure. New fundamental research based on designer proteins highlights important communication processes in the human body. In the long term, this new knowledge may lead to pharmaceuticals with fewer side effects. |
| Scientists find new strategy to combat bacterial infections Posted: 29 Jan 2014 04:58 AM PST Increasing numbers of bacteria are developing antibiotic resistance. This forms a significant challenge in the battle against bacterial infections. Scientists have identified a chemical substance with the potential of acting as a new drug to treat bacterial infections, particularly urinary tract infections. This candidate drug does not destroy pathogenic bacteria, but rather disarms them. The benefit of this new strategy is that useful bacteria are unharmed and there is a lower risk of the development and spread of resistance by bacteria. |
| Imaging the development of diabetes: Visualization of a human autoimmune disease in animal models Posted: 29 Jan 2014 04:58 AM PST Researchers have developed a technique to study the inflammatory process that takes place in the pancreas during the natural development of type 1 diabetes, allowing for real-time and repeated non-invasive imaging of individual islets of Langerhans. The technique enables the visualization of a human autoimmune disease in animal models that gives us a way to watch the body´s response to new therapeutic strategies that attempt to save islets from this deadly immune system attack. |
| Protein synthesis and the element of chance Posted: 29 Jan 2014 04:58 AM PST In the process of protein synthesis there is a "stochastic" component, i.e., involving random chance, which influences the time the process takes. This aspect has been investigated by two research scientists. |
| Discovery of mechanism by which sex hormone regulates aggressive behavior in male birds Posted: 29 Jan 2014 04:54 AM PST Researchers have discovered a hormonal mechanism for controlling aggressiveness in male birds. The team hope this may lead to a method of reducing aggressive behavior in humans. |
| Arsenic, mercury, selenium in Asian carp not a health concern to most, research shows Posted: 28 Jan 2014 01:34 PM PST Researchers have found that overall, concentrations of arsenic, selenium, and mercury in bighead and silver carp from the lower Illinois River do not appear to be a health concern for a majority of human consumers. |
| Skin cell response to environmental stimuli like viruses may predict type 1 diabetes Posted: 28 Jan 2014 12:39 PM PST Type 1 diabetes is a genetically-driven autoimmune disease of pancreatic beta-cells, whose origins remain unknown. Researchers have discovered that skin cells from patients with type 1 diabetes display abnormal activity triggered by immune response mechanisms to environmental stimuli like a viral infection. |
| Researchers open door to new HIV therapy Posted: 28 Jan 2014 12:39 PM PST A structural biologist and cell biologist have identified a new target for possible anti-AIDS drugs that would complement the current cocktail of drugs used to keep HIV in check.
