Parachuting allows krill to eat and run

...hales. Like many other small pelagic animals, they perform daily vertical migration (DVM), in which they occupy the upper ocean layers at night to eat and the deeper layers by day to hide. Previous research has shown that this behavior may be a rapid means of transporting carbon to the ocean's interior. Howe...

Hopkins researchers discover genetic switch that turns off an oxygen-poor cell's combustion engine

... molecules. ATP supplies energy the cell needs to perform each of its many chemical reactions and tasks, and in this way acts as the "currency" for the cell's energy economy. A report on the work, done with mouse cells genetically altered to lack the HIF-1 gene, appears in the March 8 issue of Cell Me...

Loosen leash on cancer protein 'watchdog,' researchers say

...hereditary cancer, and, if used properly, it might perform well without elevating the risks of aging that other groups have found. The benefits seem to outweigh the risks. "We'd like to expand the research and look into how Mdm2 and p53 affect other cancer predispositions. If we can find the right length fo...

US woman gives birth to baby from world's first frozen donor egg bank

...em for women over age 35 is that their eggs do not perform well enough to achieve pregnancy. The first frozen egg bank will offer women the opportunity to better manage their own infertility, which is often a daunting and difficult path. Many problems that exist with fresh donor eggs such as synchronizi...

Is the brain wired for faces?

...here is much that remains unknown about how humans perform this task. "We found that faces aren't special in the way many scientists once thought," says Maximilian Riesenhuber, PhD, assistant professor of neuroscience and senior author of the study. "Rather, they are particular group of objects which the b...

Researchers identify genes in fruitflies that may shed light on human cancer spread

...ssect their function. The researchers also hope to perform more whole genome analyses to identify genes that interact with those already known to play a role in cell migration and metastasis. ...

Value of services performed by insects tops $57 billion in US

...Science today (April 1). "Most insects tirelessly perform functions that improve our environment and lives in ways that scientists are only beginning to understand," Losey says. "Don't let the insects' small stature fool you - these minute marvels provide valuable services." The study found that native ins...

The loss of a protein favors lung tumor growth

...fended at the University of Navarra. In order to perform the study she began with prior studies from her laboratory, which demonstrated that the protein αCP4 appears in the tissue cells that coat the normal lung, and which, nevertheless, are lost in the first phases of lung cancer as well as in 67% percent...

Afghanistan to protect wildlife and wild lands

...the 1970s, and in recent years he has continued to perform some of the only wildlife surveys in the high Pamirs of China, Tajikistan and Afghanistan. Dr. Schaller's years of dedicated research has also led to the project's plans to bring the governments of Afghanistan, Pakistan, Tajikistan, and China togethe...

In-home sensors spot dementia signs in elderly

In fact, many elders' desire to perform well during doctor visits make them walk faster than their normal daily paces, masking changes that may be clinically relevant, researchers say. Hayes and her colleagues predict that as healthy elders begin to develop cognitive impairment, they bec...

Stanford snake venom study shows that certain cells may eliminate poison

...kes and other creatures, mast cells probably won't perform as well against every type of venom. "We expect that there will be some snake venoms that either are not affected by mast cells at all or perhaps even elicit more pathology due to their ability to activate mast cells. It all depends on the balance ...

DOE JGI, a national user facility, has sequenced or is in the process of sequencing over 380 organisms, more than any other institution i...

Drug discovery team to explore newly discovered deep-sea reefs

AUVs have been frequently used in oil exploration and also in a variety of other research programs for mapping purposes, but the Miami researchers believe this is the first time an AUV has been used to map deepwater coral reefs. Miami's Dec...

Teasing out tissue from blood
