Pressure system secrets could help long range forecasts.
The rise in levels of greenhouse gases has halted an oscillation of air pressures over the Arctic, bringing warmer, wetter winters to Northern Europe, Siberia and Alaska. The shift could get worse with increasing CO2 emissions, delegates heard this week at the American Geophysical Union meeting in San Francisco, California.
The trend is unlikel

Microscope captures mitochondria bopping to a beat.
An intricate mesh of tubes wiggle, worm-like across the screen. “They’re speeding,” says Tim Richardson proudly, watching mitochondria, the cell’s energy generators, zoom around the cell. His controversial microscopic method is shooting the cell’s innards as they’ve never been seen before.
Live cell imaging has revolutionised cell biology over th
Vaccinations may increase death toll.
Inadequate vaccines can the encourage emergence of nastier bugs, placing the unprotected at risk, a new mathematical model shows. The effect could undermine future vaccination programmes.
Many vaccines save people from dying of a disease, but do not stop them carrying and transmitting it. Over a few decades this may cause more virulent strains to evolve, predict Andrew Read and his colleagues of the University of Edinburgh, UK 1
Satellites have detected the shifting forces that weave the Northern Lights.
A group of four spacecraft has given scientists their first glimpse of the immense electrical circuit above the Earth that creates the shimmering veil of the aurora borealis, or Northern Lights 1 .
In January 2001 the four satellites of the European Space Agency’s Cluster mission encountered a beam of electrons moving away from the Earth near the North Pole. The beam was on the outwa

Stem cells’ fates are a multiple choice.
A single stem cell from adult mouse muscle can form enough blood cells to save another animal’s life – and still switch back to making brawn, researchers announced at the Washington meeting of the American Society for Cell Biology this week.
Stem cells found in mashed up muscle can migrate into the bone marrow and make blood cells 1 . Muscle

The Sun’s violent outbursts have deep and twisted origins.
The Sun’s violent eruptions of material and magnetic energy have deep and twisted origins, researchers told this week’s American Geophysical Union Meeting in San Francisco, California.
These coronal mass ejections (CMEs) cause the aurora, seen at the Earth’s poles, and can knock out spacecraft. An understanding of what drives CMEs may one da
Researchers from Delft University of Technology in The Netherlands have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to…
The integration of efficient, scalable, and cost-effective nanoscale lasers is essential for optical interconnects, medical diagnostics, and super-resolution imaging. Particularly, telecom-band NW lasers are promising for on-chip coherent light sources…
Smile for the camera! An interaction between an elliptical galaxy and a spiral galaxy, collectively known as Arp 107, seems to have given the spiral a happier outlook thanks to…
Research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. In processes such as embryonic development, wound healing…
