Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...e National Academy of Sciences. Ultrasonic scans reveal fetal hydronephrosis, or enlargement of the kidney, in approximately 1 in every 100 human fetuses. The condition results from impairment of passage of urine from the kidney to the bladder. About 20 percent of those cases lead to clinical complication...

Alarming decline in Nepal's rhinos and tigers in former Maoist stronghold

...two years in one of Nepal's premier national parks reveal an alarming decline in tiger and rhino populations, indicating widespread poaching. The area only became accessible for visits since the ceasefire between the Maoist insurgents and government troops a month ago. Since 1986, 70 rhinos were translocat...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

... are and how they respond to their environment-may reveal the secret lives of cells in both health and disea...eriment, the scientists analyzed a model system to reveal its lateral organization. First they used lipids with either ''short'' or ''tall'' chemical structur...

Scientists use gene signatures to match cancer and other diseases with potentially effective drugs

...ent for that disease. Conversely, the system can reveal the molecular mechanism of a treatment that is effective but whose method of action has been a mystery, and that knowledge can lead scientists to other, similarly-acting drug candidates. The gene signatures are captured by devices called microarray...

A splice of the action: Translational role for WT1 isoform

...l human cancers. Dr. Hammarskjold and colleagues reveal that WT1 works not only at the transcriptional level, but also at the post-transcriptional level to regulate gene expression. The WT1 gene encodes two major alternatively spliced protein isoforms: WT1(+KTS) and WT1(-KTS). While WT1(-KTS) has an esta...

The brain's motivation station

...agues report brain-scanning studies in humans that reveal how specific reward-related brain regions "alert" the brain's learning and memory regions to promote memory formation. In their studies, the researchers asked volunteers to participate in two types of reward-related tasks as they scanned the subject...

The appearance of your hands can reveal your age, study finds

...ng. "The good news is, although your hands may reveal more about your age than you desire, there are remedies out there," said Dr. Guy. "A good medical skincare regimen that focuses on the hands can be highly effective in maintaining skin thickness and fullness. Non-surgical procedures like laser trea...

Blood-compatible nanoscale materials possible using heparin

...tablish a structure-activity relationship that may reveal lead compounds for new drug development. Recent discoveries include a synthetic method for preparation of heparin in quantities large enough for use in medical treatment. ...

Cutting calories slightly can reduce aging damage

...exercise is equivalent to taking a short walk. To reveal the workings of the body's chemical climate when aging-related damage happens, UF researchers tracked levels of biomarkers - chemicals and molecules present in the liver - in groups of rats. The liver, a crucial organ for maintaining good health duri...

miRNA-mediated silencing of mRNAs

...ature. Dr. Izaurralde explains that, "Our findings reveal that miRNAs silencing gene expression by at least two independent mechanisms: by repression of translation and/or by induction of mRNA degradation. This provides an explanation for changes in mRNA levels observed at least for a subset of miRNA target...

Corals switch skeleton material as seawater changes

...g and ocean acidification, Ries said, because they reveal that although corals can adapt mineralogically to altered seawater chemistry, doing so slowed the corals' rate of growth by nearly 65 percent. "This provides us with further evidence that corals are extremely sensitive to rapid environmental change,...

Biologists find regions of rice domestication

...d and domesticated, and found genetic markers that reveal the two major rice types grown today were first grown by humans in India and Myanmar and Thailand (Oryza sativa indica) and in areas in southern China (Oryza sativa japonica). A paper describing the research was published June 9, 2006, in the on-li...

Scientists take 'snapshots' of enzyme action

...s of the catalytic action," Swaminathan says, "and reveal a mechanism that is different from what had been known about this process." Previously, it had been believed that all the "players" -- the enzyme, cofactor, and substrate -- came together at a particular time to perform the function of transferring ...

Diabetes hits 275 Australians each day as pandemic spreads

...ssure) and chronic kidney disease. The statistics reveal that in Australia each year: Approximately 100,000 adults develop diabetes (275 people daily) More than 200,000 people progress from being overweight to being obese (nearly 600 people daily) 400,000 adults develop hypertension, and 270,000 adult...

Computational analysis shows that plant hormones often go it alone

Primates take weather into account when searching for fruits

New findings reported this week reveal that at least some primates can use their stored knowledge of recent weather as a tool for guiding their foraging behavior when searching for ripening fruit. The work, which potentially informs our understanding of how cognitive skills developed in h...

A dichotomy in migration patterns found for sea turtles in east Atlantic

...pulation also includes oceanic animals and thereby reveal that adults in the eastern Atlantic occupy very different habitats and undertake two distinct foraging strategies. The differing strategies correlate with body size, which may be linked tothe different diets of the two groups. Turtles migrating to ...

NHGRI announces latest sequencing targets

...s. Therefore, this set of ten targets is likely to reveal the origins of other genes important for multi-cellularity in all such animals, including humans. The ten targets, all of which involve relatively small genomes, include six to be sequenced at high-density genome coverage: Capsaspora owczarzak; Spha...
