Dwarf mistletoe reveals its sexual secrets

...ealed another floral first that's "really going to shake things up" in the world of plant reproduction science. The male portion of the dwarf mistletoe sends out its pollen tube prematurely (or pre-emptively, depending on your interpretation). "In all previously described flowering plants,...

A whole lot of shaking goin' on triggers early hatching in red-eyed tree frogs

...a particular characteristic of the vibrations that shake the clutch -- not only the speed of these vibrations, or how hard the clutch is shaken, but the length of and time between the movements that signal the embryos to hatch. Undisturbed, red-eyed tree frog eggs usually hatch six to eight days after fert...

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

...chnique that uses pulses of near-infrared light to shake the DNA molecule loose from the carbon nanotube after they've entered the cell. The idea is to use the nanotube to deliver therapeutic molecules of DNA, RNA or protein directly into the cell nucleus to fight various infections and diseases. "Nanotech...

What causes psoriasis?

...to be very powerful. Recent experiments could even shake some long-held beliefs: The IMP-researchers found that they could induce psoriasis even in mice lacking B- and T-cells, that is without a functioning immune system. This result contradicts the picture of an autoimmune disease mediated by T-cells as t...

Ultrasound and algae team up to clean mercury from sediments

...eviously determined that ultrasonic vibrations can shake mercury loose from sediment. "We found ultrasound to be very effective at getting mercury out of sediment and into water," He explained. "But then we needed a third party to get the mercury out of the water. That's how we got the idea to add a biolog...

MSU researchers shake out basis for rice domestication

...ours were spent in the greenhouses where we had to shake the plants and record the various degrees of shattering," Sang said. "Even with all the advances in technology, a careful firsthand observation proves to be essential for biological research." The researchers then developed a new method for rapid an...

News tips from the Journal of Neuroscience

...Antoine Triller Generally, it's not a good idea to shake or move a ladder sideways with someone on it. However, that seems to be exactly what synaptic scaffolding proteins do. In this week's Journal , Hanus et al. monitored the GABA/glycine receptor scaffold gephyrin by tagging it with the yellow fluoresc...

Fishy cooperation

...actively recruit moray eels through a curious head shake made close to the moray eel's head to which the eel responds by leaving its crevice and joining the grouper. Groupers showed such recruitment more often when hungry. The observed role division comes "naturally" to two predators with different hunti...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...es, as in politics, some groups just can't seem to shake the label ''extremist.'' So it is with archaea (ar-KEY-uh), a collection of bacteria-like microorganisms whose unique genetics and chemical structure separate them from all other living things. For years, biologists have pigeonholed archaea as extr...

Three young scientists at Yale honored with Sloan Foundation Fellowships

...floppy that the recoil of individual photons would shake it measurably? According to Harris. "The answer has been debated since the first days of quantum mechanics, and will provide new insight into an astonishingly broad range of issues ranging from new types of unbreakable cryptography to experiments whi...

Smithsonian study concludes Caribbean extinctions occurred 2M years after apparent cause

...entists and colleagues report a new study that may shake up the way paleontologists think about how environmental change shapes life on Earth. The researchers summarized the environmental, ecological and evolutionary consequences for Caribbean shallow-water marine communities when the Isthmus of Panama was...

Molecular rendezvous caught on camera

...ith a kind of "handshake". Anyone who has tried to shake someone's right hand with his or her own left will have had a little trouble: the right and left hands do not fit together. In the same way, some molecules that exist in both a right-handed (D) and left-handed (L) configuration can tell if others the...

Clones on task serve greater good, evolutionary study shows
