Census of Marine Life historians detail collapse of bluefin tuna population off northern Europe

...s lead author Steve Teo: We found that bluefin get warm when they undergo courtship and our physiological measurements indicate they are vulnerable to overheating while in the Gulf of Mexico. Gulf of Mexico eddies tornado-like features that move counter-clockwise and cause a retention of food -- may al...

Taming the anthrax threat

...ickly-multiplying organism once it gets inside the warm lungs of a host. Bacillus anthracis can cause infection elsewhere in the body, but is most serious and potentially deadly when its spores are inhaled. Bergmans team focused on the mystifying step in anthrax infection when the bacteria pass unrecog...

Humboldt squid on the move

... a year or two after a strong El Nio event brought warm water northward along the coast and into Monterey Bay. From 1999 until 2002, just a few Humboldt squid were seen during ROV dives. In 2002, however, large numbers of squid appeared after a mild El Nio event, and they have been abundant ever since. ...

Changing climate will challenge Northeast agriculture, CU expert warns

...stry also could be threatened as winters become so warm that the "winter chilling" period required for maximum flowering and yield is no longer met. "With a lower emissions scenario, apple and other affected tree fruit crop industries would have several more decades to adapt, possibly switching to differe...

Scientists find brown fat master switch

... in mice and in human infants, where it keeps them warm by dissipating food energy as heat, instead of storing it as white fat," said Spiegelman, senior author of the paper. "Human adults don't have much brown fat, but there is some, and from a therapeutic perspective the question is whether that pathway ...

First all-African produced genetically engineered maize is resistant to maize streak virus

...aize fields over a wide geographical area. Under warm and wet conditions, a long-bodied morph of the leafhopper C. mbila emerges, but this form only travels short distances of 10 meters or less, thus limiting its damage to crops. Under drought conditions, a stronger, short-bodied morph that can fly gre...

March of the giant penguins

Not only did penguins reach low latitudes during this warmer interval, but they thrived: more species are known from the new ...

Arctic spring comes weeks earlier than a decade ago

...seasons are changing and it is not just one or two warm years but a strong trend seen over a decade. To uncover the effects of warming, the researchers turned to phenology, the study of the timing of familiar signs of spring seen in plants, butterflies, birds, and other species. Shifts in phenology are ...

Agonized death throes probable cause of open-mouthed, head-back pose of many dino fossils

...appears to be a good indicator that the animal was warm blooded. Animals with lower metabolic rates, such as crocodiles and lizards, use less oxygen and so might have been less traumatically affected by hypoxia during death throes, Padian said. Padian acknowledged that many dinosaur fossils show signs t...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...in seconds. We developed a solution where we can warm up tissue in under five minutes and still get no ice formation, says Dr. Song, adding that ice formation aside, it is difficult to thaw rock-solid tissue at room temperature in a matter of seconds, meaning the current approach could have extremely li...

Research finds evidence tropical cyclones have climate-control role

...n for this. Cyclones and hurricanes appear to pump warm water down and bring cold water to the surface. Mixing down buoyant, warm water lessens the density of the cold water and allows it to rise " The study did not examine deep...

Tropical birds have slow pace of life compared to northern species, study finds

This suggests the physiology of tropical birds is indeed different from that of temperate birds and this affects their metaboli...

This means it will be possible to predict the implications of the increasing temperatures on Earth today resulting from increase...

The TRPM8-deficient mice did not lose their ability to feel pain in response to extreme cold, as evidenced by responses similar to wild type mice when exposed to -1 C cold...
