Tracking forest threats

Alerts from an early warning system developed in part by DOE’s Oak Ridge National Laboratory could help protect forests across the U.S. from the threats of insects, disease and wildfire. Led by the USDA Forest Service, the multi-agency project uses h…

Oldest objects in solar system indicate a turbulent beginning

LIVERMORE, Calif. — Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system.
The findings m…

Improved method developed to locate ships in storms

There are already systems that detect ships at sea, but a group of engineers from the UAH, led by the researcher Raúl Vicen, has introduced a new development, involving “the use of artificial intelligence techniques and improvements in the te…

Natural (born) killers: What do they really do?

Our immune systems contain three fundamentally different types of cell: B-cells, T-cells and the mysteriously named Natural Killer cells (NK cells), which are known to be involved in killing tumour cells and other infected cells. Experiments to in…

Mimicking photosynthesis path to solar-derived hydrogen fuel

Inexpensive hydrogen for automotive or jet fuel may be possible by mimicking photosynthesis, according to a Penn State materials chemist, but a number of problems need to be solved first.
“We are focused on the hardest way to make fuel,” said Thom…

Back to the roots of the solar system

Planets form in disks of dust and gas that surround young stars. A look at the birth places means a journey into the past of the earth and its siblings. Now, astronomers have been able to obtain detailed images of the protoplanetary disks of two s…

Efficacy of tuberculosis vaccine enhanced

Nele Festjens and Nico Callewaert of VIB and Ghent University have improved the efficacy of the vaccine for tuberculosis. The new vaccine affords – as already proven in mice – better protection against the disease. The development of a new tubercul…

How nature’s patterns form

When people on airplanes ask Alan Newell what he works on, he tells them “flower arrangements.”

“Most patterns you see, including the ones on sand dunes or fish or t…

Choose less contaminating products thanks to eco-labeling

Ensuring the sustainability of the products we use is a fundamental challenge for society, and is becoming ever more important for consumers and companies. A researcher from the University of Santiago de Compostela (USC) has come up with an ec…

TORONTO, Ont., February 16, 2011 — One in five homeless people with tuberculosis die within a year of their diagnosis, according to a study led by St. Michael’s Hospital’s Dr. Kamran Khan. And that number remains unchanged over the last decade de…

Running on a faster track

What matters for commuters is not just if the train will be on time, but how long the journey will take. It’s an important factor in public transportation and can make the difference in helping commuters choose mass transit over more polluting and c…

Gene that regulates immune system linked to preeclampsia

Researchers at North Carolina State University have discovered that the placentas of women who suffer preeclampsia during pregnancy have an overabundance of a gene associated with the regulation of the body’s immune system. Their discovery may lead …

Stardust NExT set to meet its second comet

Stardust NExT must love comets. On Valentine’s Day the spacecraft will get up close and personal with its second.
It’s been seven years since the original Stardust danced with Wild 2 out beyond the orbit of Mars, capturing a thimbleful of co…
