Analysis of long-term changes in Pacific Ocean temperatures may provide additional data with which to evaluate global warming hypotheses.

“Abrupt changes in water temperatures occurring over intervals of up to 25 years suggest that global warming may result as much from natural cyclical climate variations as from human activity,” said Benjamin Giese, oceanography professor in the College of Geosciences.

“Climate models constructed here at Texas A&M University were used to a

Before developers decide to make the desert bloom, they better take a look at what’s under the surface of the Earth.

That’s the conclusion of research by Texas A&M University geologist Mohamed Aly, who’s using GIS (geographic information systems) techniques to conduct engineering geomorphology assessments of some of Egypt’s newest urban developments to predict – and thus avoid – foundation problems stemming from instabilities in the underlying bedrock.

Below is an advisory distributed today by the Proceedings of the National Academy of Sciences (PNAS). The paper can be found in the online early edition of PNAS at www.pnas.org.

The study, conducted by Dr. Cassian Yee, a researcher at the Fred Hutchinson Cancer Research Center, involved 10 people diagnosed with advanced melanoma. For each patient immune system cells able to identify and target melanoma wer

A first in Canada, the Alberta Research Council (ARC) reached a milestone in the technical development of its own version of solid oxide fuel cell (SOFC) technology. ARC scientists are developing a proprietary micro solid oxide fuel cell (µ-SOFC) source of energy for small-scale portable applications such as laptops or personal digital assistants (PDAs).

“This is an important milestone as we pursue our strategic initiative in fuel cell technologies,” says John Zhou, manager, Advanced Materi

Danish authors of a study in this week’s issue of THE LANCET provide reassurance to pregnant women—maternal fever in the early stages of pregnancy is probably not a risk factor for miscarriage or stillbirth.

Increased maternal body temperature can cause fetal death in some animals, which has lead to the suspicion that maternal fever early in pregnancy (when embryonic development is at a critical stage) could have a similar effect in the human population.

From 800 km in space, you would have to squint really hard to see one of these – a micron-sized phytoplankton and its armoured shell. But when a lot of them get together, say, a few trillion or so…

…what you see is the image below from the European Space Agency’s Medium Resolution Imaging Spectrometer (MERIS) instrument. The sensor, carried onboard the Envisat satellite, acquired imagery of a phytoplankton bloom that occurred this summer in the north Atlantic, off the coasts of Nova Scotia
