Caribbean frogs started with a single, ancient voyage on a raft from South America

...erant of salt water. In addition to the study's discoveries about Caribbean and Central American frogs, the research also revealed and defined an unusually large and unpredicted group of species in South America. "The South American group may have more than 400 species and is mostly associated with the large...

Undergraduate research shows leaderless honeybee organizing

...ed knowledge” – in other words, absorbing the past discoveries of scholars and scientists. But University of North Carolina at Charlotte senior biology major Andrew Pierce went beyond the textbooks and uncovered something previously unknown. Pierce’s discovery has to do with detecting a significant new detail c...

UI anthropologist, colleagues discover remains of earliest giant panda

... the National Academy of Sciences (PNAS). Previous discoveries of teeth and other remains made between 1985 and 2002 had failed to establish the animal's size. Ciochon says that the ancient panda (formally known as Ailuropoda microta, or "pygmy giant panda") was probably about three feet in length, compared t...

Definitive evidence found of a swimming dinosaur

... existed documenting the behavior. Several earlier discoveries were later found to have been produced on dry ground or categorized as ghost traces, possible undertracks preserved in lower layers of sediment. "The trackway at La Virgen del Campo opens the door to several new areas of research," said Costeur. ...

Detecting cold, feeling pain: Study reveals why menthol feels fresh

...ation. The finding is the latest of a series of discoveries led by the Julius lab on the molecular mechanisms of temperature sensation and pain. In 1997, the lab cloned the gene for the capsaicin receptor, the main pungent ingredient in some chili peppers (Nature, Oct. 23, 1997), and in 2000 reported that, in...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

...ent infections from occurring. "Some remarkable discoveries have been made using insects that have subsequently allowed important advances in understanding how the human immune system works." As part of their innate immune system, insects use an enzyme called phenoloxidase to produce reactive molecules tha...

Nitric oxide: Key to cardiovascular and pulmonary function and drug effectiveness

...tamler, whose laboratory has made many fundamental discoveries about the role of nitric oxide in human biology, including the discovery of SNOs' ubiquitous role in human health and disease. "When nitric oxide function is impaired by disease, therapeutic agents like beta-agonists in asthma and adrenergic stimulan...

Corals -- More complex than you?

...erseas, and we are being left behind. If important discoveries leading to new technologies are made, we will have to pay to import them. "Sequencing a coral genome is a real contribution which Australia can make to human knowledge ?with potential benefit to society, the environment and the economy." ...

Rare soft-shell turtle, nesting ground found in Cambodia

...and archipelagos where further exciting biological discoveries will almost certainly be made.?He said a further survey of the area by an international team of flora and fauna experts was planned for July 2007. The turtle survey team consisted of Cambodian Fisheries Administration staff and the Cambodian Turtl...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...tch?that researchers have been looking for." The discoveries are critical to future research efforts in designing new generations of plants, Mittler said. "A lot of things that occur in the chloroplast are important for production, for growth, for response to the environment," he said. "So this is a very bas...

Discovery of new cave millipedes casts light on Arizona cave ecology

... Voyles indicates there are a lot more exciting discoveries to be made. "With 170 known caves [on the BLM Ariz...omists, the researchers believe additional species discoveries are likely. The new millipede genus will be named in honor of NAU ecologist, John Prather, who di...

Bones in motion: Brown scientists to create new 3-D X-ray system

... organizations and a major supporter of pioneering discoveries in science, engineering and medical research. The system will fill a void in medical and scientific imaging. Right now, researchers trying to understand the complex motions of bones and joints are held back by technology. Computed tomography...

Lighting up life: Cold Spring Harbor Protocols presents tips for creating glowing plants

...tein (GFP) has allowed biologists to make many new discoveries regarding how living cells function. But one kingdom of life—plants—has presented special challenges to GFP detection: plants harbor tough cell walls and enormous subcellular structures that interfere with visualization, and their natural green pigm...

Mechanism of nicotine's learning effects explored

...ished by Cell Press. The researchers made their discoveries by analyzing the electrophysiological properties of neurons in slices of mouse brain, as they treated the slices with nicotine or with drugs that prevent nicotine’s action. Specifically, the researchers studied the neurons of the prefrontal cortex, w...

Researchers learn what sparks plant growth

...ast decade, Chory has made a number of significant discoveries involving a key family of plant hormones called brassinosteroids, as well as the receptors for the hormones and the genetic factors that regulate production and uptake of the hormone in the different layers of plant tissues. According to Chory, brass...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

... think what this says is that when people make new discoveries now, if they want to get maximum information out, they have to immediately handle material in a way that first of all will avoid contamination and, second, ensure that whatever is there gets well preserved because it can be interrogated." The scra...

Cancer-killing invention also harvests stem cells

... the University of Rochester, King wrote about his discoveries in "Using Protein-Functionalized Microchannels for Stem Cell Separation," Paper No. ICNMM2006-96228, Proceedings of the ASME, June 2006. King's team includes scientists at StemCapture, Inc., a Rochester company that bought the University patent for ...

Biologists develop large gene dataset for rice plant

... Small RNAs are considered one of most important discoveries in biotechnology in the last 10 years. Because they are so much smaller than mRNAs, small RNAs went unnoticed for many years, or were considered biologically unimportant, said Meyers. Small RNAs are now known to play an important role in gene regu...

Scientists find new genes for Crohn's disease

...eases (NIDDK) agreed, saying that "these important discoveries not only offer new hope for better therapies for patients with Crohn's disease, but they also highlight the promise of the human genome project and subsequent investments by the NIH in large-scale, collaborative research projects to unravel the cause...

The chimpanzee stone age

...n chimpanzees is transmitted socially, and the new discoveries presented in this study shows that such behaviour has been transmitted over the course of many chimpanzee generations. Chimpanzee prehistory has deep roots! The study of our living closest relative, the chimpanzee, constantly highlights new aspect...
