RFID Tags Show Elite Bees Are Made, Not Born

by Michael Keller

Some bees in a hive have a right to complain. Researchers studying individual foraging behavior found that a minority group of elite colony members work much harder than others. 

By attaching tiny radio frequency identification tags to the backs of bees, University of Illinois scientists realized that 20 percent of bees that leave the nest to forage account for 50 percent of the total food brought back.

“We found that some bees are working very, very hard – as we would have expected,” said lead researcher Gene Robinson, who heads the university’s Institute for Genomic Biology. “But then we found some other bees that were not working as hard as the others.”

To celebrate the 15th anniversary of NASA’s Chandra X-ray Observatory, four new images of supernova remnants are being released. These spectacular cosmic vistas are the glowing debris fields that were created when massive stars exploded at the ends of their lives.
Chandra, one of NASA’s current “Great Observatories,” along with the Hubble Space Telescope and Spitzer Space Telescope, is specially designed to detect X-ray emission from hot and energetic regions of the universe. It obits up to 86,500 miles above the Earth.
To celebrate Chandra’s 15th anniversary, four new images of supernova remnants – the Crab Nebula, Tycho, G292.0+1.8, and 3C58 – were released by the space agency. These supernova remnants are very hot and energetic and glow brightly in X-ray light, which allows Chandra to capture them in exquisite detail. See a larger version here.

Missile Technology Fired At Malaria’s Heart

by Michael Keller

There may be a new weapon emerging in the fight against malaria. Researchers say they have successfully used a heat-seeking detector normally employed as part of an anti-tank weapon to quickly sense the parasite in blood during the earliest stages of infection.

Researchers at Australia’s Monash University and the University of Melbourne used an advanced imaging sensor originally developed for the shoulder-fired Javelin missile system, which is used by soldiers and Marines against tanks, helicopters or buildings.

“Our test detects malaria at its very early stages, so that doctors can stop the disease in its tracks before it takes hold and kills. We believe this sets the gold standard for malaria testing,” said Monash chemist Bayden Wood in a statement.

Look Out, Graphene: Boron Atoms Form Cages And Flat Sheets Like Carbon

by Michael Keller

Chemists working in the U.S. and China say they have discovered a new molecular structure made out of boron atoms.

They believe the structure is made of 40 boron atoms that link together into a cage, which might be useful in storing hydrogen. 

"This is the first time that a boron cage has been observed experimentally," said Lai-Sheng Wang, a Brown University chemistry professor and the study’s leader. "As a chemist, finding new molecules and structures is always exciting. The fact that boron has the capacity to form this kind of structure is very interesting."

They described their work uncovering experimental evidence for the molecule, which they have called borospherene, in a recent issue of the journal Nature Chemistry.
