Record bonefish

...eason why BTU invested in this kind of research to begin with," said Tom Davidson Sr., BTU chairman and founding member. "It's quite rewarding to uncover new information like this that bonefish may be crossing the Gulf Stream. It's what truly can lead to better understanding and managing of our fisheries...

'Scent of a woman' tells male redback spiders to find a mate

...ppropriate. Once they settle on their own web they begin molting and building up fat reserves, but once they reach sexual maturity, they cease eating and focus solely on finding a mate. If they are lucky enough to find a female, they put all of their resources -- including their life -- into it. In the pro...

Suicide risk does not increase when adults start using antidepressants, study finds

...nts. "Keeping a close watch on patients after they begin taking these drugs is a good idea--although not because these medicines are especially risky or dangerous," he says. "Patients need to be monitored to ensure they're getting the right medication in the amount that can help them feel better." ...

Research tracks whales by listening to sounds

...ile listening for earthquakes, the OSU researchers begin picking up sounds of ships, marine landslides ?and whales. An engineer at the center, Haru Matsumoto, then developed an autonomous hydrophone that can be deployed independently and Mellinger's colleagues placed seven of these instruments in the Gulf ...

Newly discovered killer cell fights cancer

...conventional dendritic cells in the spleen. IKDCs begin their lives behaving like an NK cell. After the cell encounters a pathogen, the cell switches roles from killer to dendriticlike messenger, and, according to the researchers, the swap occurs only once. Then, the cell dies and is replenished by the ...

Enzyme crystal structure reveals 'unexpected' genome repair functions

... separation either to initiate transcription or to begin NER. There were also no models for the role that XPB, which is an essential subunit of Transcription Factor IIH (TFIIH) functional assembly complex, might play in changing conformations for TFIIH's alternate roles in either transcription or DNA repai...

Data published in PNAS show antibodies can be made 10 times more toxic to cancer cells

...elop therapeutic antibodies, for which it plans to begin clinical testing next year. "We've already applied the XmAb technology used in this research to generate a suite of patented Fc antibody variants that have optimized antibody-Fc receptor affinity, which translate into increased effector functions a...

Restoring seagrass beds: Is it for the birds?

...s of this popular location. Dune restoration will begin on Tuesday, April 11, from 10am to 1pm as Dr. Dindo and volunteers from AmeriCorps plant 1,000 sea oats on the beaches of Robinson Island. Over the next two months, Drs. Heck and Dindo will also plant birdstakes in the damaged grassbeds, hoping to a...

Paleontologists learn how not to become a fossil

...zing other groups. And of course as those analyses begin to accumulate, we'll have a much clearer picture of what's missing from the fossil record and how to make corrections, producing a clearer picture of the biological dynamics of the past." ...

Rewind, please: Nature paper shows that cell division is reversible

...regulators in the cell division cycle. Now we will begin to study the triggers that set these events in motion." The findings may prove important to controlling the development and metastasis of certain cancers. It also holds promise for the prevention and treatment of birth defects and a wide variety of ...

Worm hormone discovery may aid fight against parasitic disease

...where they eventually migrate to the intestine and begin to mature. Dr. Mangelsdorf is investigating whether the homologue of DAF-12 in parasitic nematodes may regulate their maturing activity as well. If so, he said, the same pathway could be exploited to eradicate the pests, either by keeping them perpet...

UMaine teams with fishermen to study affects of trawling on seafloor ecology

...ed that if the groundfishing industry doesn't soon begin to undertake measures to conserve complex bottom habitat, there will be little chance that fishery will ever recover to levels seen 50 or 100 years ago. Small, bottom fish need complex habitat and it is clear that rock hopper gear reduces habitat com...

How can we protect patients with weakened immune systems from influenza?

...eveloping specialized assays. The researchers will begin enrolling patients this fall under the five-year program. "A major reason to study influenza is the quick-changing nature of the influenza virus," said Dr. Sullivan. The virus mutates its outer coating from year to year, a process called viral drift...

According to the study, there was a high acceptability rate among participants, as 94 percent of women said they would definitely or probably use the gel if it were available and they wanted protection from HIV transmission. ...

Researchers now able to look deep into heart to view triggers of a heart's beat

...i break down, and at the same time the centrosomes begin to form," Ferree said. One of the most striking aspects of this mechanism is the large number of accessory nuclei and centrosomes that form in the developing eggs of these Hymenopteran insects. "You only need two centrosomes, and they make hundred...

Dr. Atamna refers to this phenomenon as a "functional heme deficiency" because the cells are still forming heme, but it is trapped within an amyloid-beta/heme compound.
