Research identifies protein that signals flowering in squash plants

...ts to use a plant that is 100% inducible; in other words it absolutely will not flower unless it is induced. Then, with carefully designed grafting experiments, we can precisely control the introduction of putative florigenic signals into the translocation stream.” The authors screened nearly one hundred a...

Math that powers spam filters used to understand how brain learns to move our muscles

...ate on a similar principle; they predict which key words are “probably” attached to mail you don’t want and “learning” as they go to fine tune what they exclude from your in-box. The computer model, Shadmehr says, almost precisely duplicates the results of experiments that tested the ability of monkeys...

How plague-causing bacteria disarm host defense

.... pseudotuberculosis and Y. enterocolitica are big words for nasty, little bugs that cause what's commonly known as food poisoning. All three bacteria species find their way past the body's immune system through a sophisticated invasion system that injects the effector proteins directly into the host cell...

Statin treatment improves spatial memory in mouse models of Alzheimer's

...e animals were tested for spatial memory, in other words low long it took them to find the platform. The Alzheimer’s mice that received statin were able to find the platform while none of the transgenic mice receiving only saline were able to do so. Normal mice on statin also showed improvement in the tim...

In a report to be presented May 5 at the International Meeting for Autism Research in Seatlle, researchers from UCLA will show that children with autism can’t do this. They hear and they see, of course, but the areas of the brain that norma...

Insomnia drug can improve brain function

... the patient was able to stand up and walk, repeat words and sentences, read words, and name objects, although she was not able to speak spontaneously. Administration of the drug increased brain metabolism, and PET scans also showed improvement in cerebral areas involved in motivational processing. Alth...

Is there a pilot in the insect?

An insect brain wouldn't cope with these cumbersome, heavy, energy-consuming devices. This important work shows that this new science c...

Studies yield insight into the numerical brain

...lly, the numbers were also presented either as two words (e.g., two or eight), two digits (e.g., 2 or 8), or a mixed notation (two and 8). They hypothesized "that if the assumption of an abstract representation of numbers in the [parietal cortex] held true, the adaptation effect would be observed within ...

Taking 'chips' to the next level of gene hunting

By chopping up the DNA, amplifying the DNA next to the transposable elements and then applying these amplified copies to...

Slow brain waves play key role in coordinating complex activity

...ged with the task. Patients listening to a list of words would show strong coupling in a particular set of brain regions, but when they then had to name pictures, a different set of brain areas would show strong coupling. "We used to think that one little patch of cortex takes care of this function and an...
