UGA study reveals function of ubiquitous yet poorly understood microorganisms

...erican Society for Microbiology meeting in Toronto finds that crenarchaeota, one of the most common groups of archaea and a group that includes members that live in hot springs, use ammonia as their energy source. Chuanlun Zhang, lead author of the study and associate research scientist at UGAs Savannah Ri...

Hives ferment a yeasty brew, attract beetle pest

... the colony," says Tumlinson. "Perhaps one beetle finds and carries the yeast in and it reproduces, or, because the yeast grows on pollen in nature, perhaps bees bring it into the hive." This combination of domestic honeybees, small hive beetles and yeast produced IPA leads to combs so messy that the bee...

Journal details how global warming will affect the world's fisheries

Do fruit flies have free will?

...ad, if we ask 'how close to free will are we"' one finds that this is precisely where humans and animals differ". The next step will be to use genetics to localize and understand the brain circuits responsible for the spontaneous behavior. This step could lead directly to the development of robots with th...

Medical research scientists make ethical value judgments in research

...sue of European Journal of Epidemiology, the paper finds that the framing of the research question, identification of the problem, as well as the design and methodology of the study are all subject to value judgments by investigators. To illustrate this point, the study focuses on how value judgments are...

Childhood environment influences reproductive function

It finds that women who migrated from Bangladesh to the UK during infancy and early childhood reach puberty earlier, are taller, and have up to 103 per cent higher levels of the hormone progesterone as adults in comparison to women who migrated at a later age...

Study revises dynamin's role in nerve cell function

...synaptic vesicles within the cell. The new study finds that the enzyme is not always necessary for this process. Instead, dynamin 1 goes into action only when the synapse enters moments of especially high activity. "In that sense, dynamin 1 remains crucial, allowing the synapse the freedom to function ...

Alien plants attack using 'resource conservation' as weapon, researchers say

...But a new study by Stanford University researchers finds that invasive plants can flourish in low-resource environments by adopting efficient ways to use available resources. The finding, which sheds new light on how invaders achieve success, may change the way scientists think about invasive species and...

Hearts of male and female rainbow trout are different

...tudy begins to close the gender gap in fishes, and finds that sex differences in cardiac performance and metabolism exist in rainbow trout. These differences occur at a young age and are only realized when the trout heart is contracting and not under resting conditions. The study is entitled Sex Differe...

Investigational cancer drug targets critical proteins

...ncer. The net effect is that while the drug ably finds its target, to maximize effectiveness it may need to be modified or used in conjunction with another drug to also block hsp70, Dr. Yang says. MCG researchers are in discussions with Novartis and Kosan Pharmaceuticals about how to make one or the oth...

Researchers associate calories from newspaper dessert recipes with community obesity rates

MARSHFIELD, Wis.Research finds calorie-dense dessert recipes printed in major newspapers across the country may be contributing to obesity in large cities. The study, conducted by researchers at Marshfield Clinic Research Foundation, Marshfield, Wis., is published in the latest is...

Bacteria control how infectious they become, study finds

It's only when RfaH finds the appropriate target sequence on a bacterium's DNA that this small portion of the protein is unmasked and can then turn on a select group of genes. These genes let disease-causing bacteria infect their host while at the same time protecting the bac...

Marine scientists monitor longest mammal migration

...Research Collective, and lead author in the study, finds the record-breaking migration interesting, but is most pleased that the study validates a long held assumption that humpback whales travel to warm water areas during the winter. "It was very exciting because for years everyone said humpback whale...

Trends in bird observations reveal species' changing fortunes

... often increased in abundance, an observation that finds a likely explanation in the expansion of northern forests during much of the 20th century. The increases among forest-loving birds were most pronounced, however, among species that migrate south of the United States--a surprise, given the well-known ...

Protein averts cell suicide but might contribute to cancer

When it meets an A' on the old half, it pairs it with a T' on the new half (and vice versa); when it meets a G' on the old half, it pairs it with a C' on the new strand. In the end, there are two complete DNA molecules instead of one...

Study: Chest compressions without mouth-to-mouth better for out-of-hospital cardiac arrest

...ncet, one of the worlds foremost medical journals, finds that the chances of surviving a cardiac arrest outside a hospital setting are almost twice as high if bystanders perform chest-compression-only resuscitation instead of traditional cardiopulmonary resuscitation (CPR) with mouth-to-mouth breathing. ...
