UCSB scientists probe sea floor venting to gain understanding of early life on Earth

...ated. Haymon is interested in the large region of cooling on the sides of the mid-ocean ridge. Possibly 90 percent of the hydrothermal cooling of the sea floor occurs in these flanks, and yet these hydrothermal vents are largely unexplored. Th...

First frozen egg baby born in Canada

...trification solution. The eggs undergo super-rapid cooling at a rate of more than 20,000ºC per minute, which prevents ice crystal formation and increases egg survival to approximately 90%. The frozen eggs can then be safely stored in the Cryoleaf until it is ready for use, at which point it is carefully thaw...

Africa to take it on chin again with climate change

...tead, the new results point to a late 20th-century cooling of the North Atlantic Ocean as having been key to ...says Hurrell. "We believe the North Atlantic Ocean cooling was natural and masked an expected greenhouse-gas warming effect." Since 1990, the sea-surface temp...

Elephant seal pups suffer from ocean warming

...ually reach 130 kg. This change coincided with the cooling of the ocean at the beginning of the new century. "Despite ranging widely and foraging deeply in cold waters beyond coastal thermoclines in the northeastern Pacific, elephant seals are impacted significantly by ocean thermal dynamics", conclude the ...

New strategies to reduce hospital-aquired infections

...organisms have been recovered from drinking water, cooling towers and water distribution networks in hospitals. Dr. Cervia presented data on the efficacy of point-of-use 0.2 micron filters to provide a barrier to Legionella and other pathogens to reduce the risks from hospital water. Unlike systemic technol...

Climatologists discover deep-sea secret

... hemisphere, the southern hemisphere has entered a cooling period, which creates a decrease in the amount of deep water transported to the Atlantic Ocean from the south. The opposite effect also took place: when the climate cooled in the North Atlantic, the southern hemisphere entered a warmer period, causin...

Study Finds Moderate Hypothermia A Safe Treatment For Traumatic Brain Injury In Kids

Deep sea algae connect ancient climate, carbon dioxide and vegetation

... 33.7 million years ago was marked by rapid global cooling and the formation of large continental ice sheets on the Antarctic. "Before this study, the relationship between the global climate and the concentration of carbon dioxide in the atmosphere during the late Eocene and Oligocene was largely unknown," ...

Genetic discovery could lead to drought-resistant plants

... of T and the University of Lancaster compared the cooling rates of plants with normal, high and low levels of gene activity. From their data, they were able to link the gene to plant exhalation. The discovery is another step in understanding how plants respond to their environment. In hot temperatures, pla...

Freeze-dried mats of microbes awaken in Antarctic streambed

... species of cyanobacteria, she said. Because of a cooling trend in the McMurdo Dry Valleys, some streambeds that normally have annual summer flows have been dry in recent years, McKnight said. In contrast, the Antarctic Peninsula has warmed nearly 5 degrees Fahrenheit in the past 60 years and has seen the c...

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...0,000 years, the scientists found three pronounced cooling periods which indicate drought. Besides the ocea... Africa on the monsoon belt. The three sea surface cooling periods found by the scientists correlate to records of low lake levels. These clearly were times of...

2005 was the warmest year in a century

...ctic. In order to figure out whether the Earth is cooling or warming, the scientists use temperature data from weather stations on land, satellite measurements of sea surface temperature since 1982, and data from ships for earlier years. Previously, the warmest year of the century was 1998, when a strong ...

High-tech tags on marine animals yield valuable data for biologists and oceanographers

... to show us things like the thermal properties and cooling rates of the ocean and the structure of the water column, and they can often get valuable data that would be hard to collect by other means," Costa said. ...

Study finds evolution doesn't always favor bigger animals

...years, global climate has been exhibiting a steady cooling trend. But within the last century, as greenhouse emissions have accumulated in our atmosphere, temperatures have rapidly warmed. "If you look at most of life today, they've all been adapted to a world getting gradually cooler," said Roy. "But our ...

Deep-rooted plants have much greater impact on climate than experts thought

Medieval diaries aid scientists ascertain increase in hot spots due to global warming

...warmth, compared to all of the natural warming and cooling episodes during the past 1,200 years. The research team gathered climate change data from a number of regions in the Northern Hemisphere especially: Long life evergreen trees growing in Scandinavia, Siberia and the Rockies, which had been cored to...

Slow-frozen people? Latest research supports possibility of cyropreservation

...e often damaged due to freezing of water either on cooling or subsequent warming to room temperature. "Damage of the cells occurs due to the extra-cellular and intra-cellular ice formation which leads to dehydration and separation into the ice and concentrated unfrozen solution. If we could, by slow cooling...
