Clock molecule's sensitivity to lithium sheds light on bipolar disorder

...y studies, including those here at Penn, suggest a relationship between the human circadian clock and metabolism. ...Obesity, and Metabolism are also interested in the relationship between the control of the circadian clock and metabolic diseases such as obesity and diabetes. "The...

Formation of cellulose fibers tracked for the first time

...rected patterns. "Many scientists had suspected a relationship between cellulose synthase and microtubules, but the exact nature of the interaction was hard to pinpoint," Ehrhardt said. "The microtubules act as more than a general scaffold for organizing the cell wall; individual elements of the microtubule arra...

Study finds evolution doesn't always favor bigger animals

...effectively dissipate heat. However, this simple relationship doesn't explain why ostracodes and other cold-blooded creatures that do not regulate their internal body temperatures, such as mollusks to turtles, also follow this rule. "It is a bit of a puzzle why Bergmann's Rule holds in cold-blooded animals li...

Extinctions linked to climate change

...n seen as an enigma is now understood as a complex relationship between global warming and major extinction of species. "This new study is a breakthrough, and the powerful synergy between pathogen transmission and climate change should give us cause for concern about human health in a warmer world," said Andrew...

New mechanism for essential genome-wide gene silencing identified

...it makes sense that it might exist in an either/or relationship with acetylation or ubiquitylation." Another observation made during the study was that slightly higher levels of sumoylation occur near the tips of the chromosomes, the telomeres, which are known to play a central role in maintaining genomic stabil...

El Nino events affect whale breeding

...an international team of scientists found a strong relationship between breeding success of whales in the South Atlantic and El Nino in the western Pacific. The results are published this week in the On-line journal Biology Letters. Southern right whales migrate from the South Atlantic to the Southern Ocean to f...

Measuring artery repair cells could become new heart disease test

Sex: It's costly but worth it. Just ask a microbe

The next time you mutter about the high cost of relationship maintenance, take comfort in knowing that microbes share your pain. In the first study to examine the cost of sexuality in microbes, Jianping Xu, associate professor of biology at McMaster University, found that sex exacts physical, morphological an...

Higher carbon dioxide, lack of nitrogen limit plant growth

...study, the longest of its kind, sheds light on the relationship between carbon dioxide emissions and plant productivity. In the experiment, scientists grew 16 different grassland plants in 296 field plots. The plots were exposed to both ambient and elevated carbon dioxide levels, and varying levels of nitrogen. ...

Not just the birds

...iminated the significance of the perimeter-to-area relationship that is so clearly evident on fox-free islands," say the authors. Previous studies have focused on trophic cascades in marine ecosystems, showing that top predators can indirectly alter plant productivity, with varying effects. Most studies on land...

Fruit fly reveals a potential connection between dementia and cancer

...it-fly model of Alzheimer's disease to examine the relationship of cell-division proteins to neurodegeneration. The power of this model, which recapitulates key features of the human disease, lies in the ability to use genetic tools to establish a causal connection between a molecular pathway and neuronal death. ...

Heparin prepared synthetically could replace animal-derived drug

...gical activities to establish a structure-activity relationship that may reveal lead compounds for new drug development. Researchers at MIT first prepared a synthetic heparin, but, in amounts of less than 1 microgram, it was insufficient to treat humans, says Linhardt. One human dose of heparin is approximately ...

Confidence in memory performance helps older adults remember

"One's sense of control is both a precursor and a consequence of age-related losses ...

Legume compounds may help cancer treatment

...are produced by legumes during the early symbiotic relationship with soil bacteria known as rhizobia. Rhizobia induce legumes to form tiny new root organs called "root nodules." The bacteria live in the nodules and provide the plant with useable nitrogen it can convert into proteins. CILR Chief Investigator Pro...

World Trade Center identifications pushed forensic DNA technology

Free-radical busting antioxidants might not promote healthy hearts

...ary to widely accepted opinion, the group found no relationship between the levels of oxidized cholesterol in blood vessels and the severity of heart disease. This might help explain the disappointing results of clinical trials with other free radical-scavenging antioxidants, such as Vitamin E, which have shown n...

Possible brain hormone may unlock mystery of hibernation

...Pc levels rose. Further study revealed an inverse relationship between HPc levels in the blood and brain. While HPc levels dipped in blood, the putative hormone rose dramatically in cerebral spinal fluid, they reported. Likewise, HPc levels decreased abruptly in spinal fluid when hibernation terminated. The res...

Protein found to control tumor growth in certain breast cancers

...in these cells. Our future studies will assess the relationship between the pathway uncovered in breast cancer and other hormone sensitive malignancies. Those studies may help in the development of new therapeutic approaches with the potential to stabilize or even eradicate hormone-sensitive tumors." ...
