Study finds evolution doesn't always favor bigger animals

...tined to be significantly warmer. What are animals going to look like when everything must adapt to a warmer world? Size correlates with many aspects of the biology of an animal so changes in size are likely to translate into substantial ecological changes. A better prediction of the biological effects of ...

New cellular flaw found in some virulent breast cancers

...n treat those patients with the inhibitor. "We are going to see in the next five years a movement away from treating all tumors with the same drugs, and instead match specific drugs to tumors based on their molecular characteristics," said Sicinski, who is also an associate professor of pathology at Harvar...

Stanford study of owls finds link in brain between sight and sound

...sen said. "The fundamental mechanisms are probably going to be the same in all vertebrates, as even frogs and fish have gaze control." All animals have to be able to attend to certain stimuli and ignore others. "Now that we have found that the principle applies in owls as well as monkeys, we can figure ou...

Medical experts: US unlikely to have enough vaccines to stop avian flu

...ldwide. "It surprised me that they thought it was going to be this bad," said Wändi Bruine De Bruin, lead author of the study and research faculty member in the Department of Social and Decision Sciences at Carnegie Mellon. The survey also included 17 non-medical experts from a variety of fields who were...

Researchers release new variety of asparagus

...ast a dozen trials, but we need to keep the trials going for a while longer because it may be affected by weather or diseases that only occur occasionally," Roose said. "It will take several years before significant amounts of this new variety appear in the market." Asparagus, a perennial vegetable, has b...

Successful cell engineering may lead to mad cow prevention, say researchers

...," Westhusin says. "That's where more research is going to be needed and where the process goes from here." Westhusin has been involved in several cloning "firsts," among them the first cloning of a cat in 2002 and a white tailed deer in 2004. ...

'Executive' monkeys influenced by other executives, not subordinates

...r example, do more to determine where the group is going to go. So there's more information to be gleaned by finding out where high-status individuals are looking. Also, it's fairly important, if you're a low-ranking macaque, not to compete with a high-ranking individual, so you want to know where they're ...

How does the brain know what the right hand is doing?

...tion is at least partly driven by outflow commands going to the muscles. There were no incoming signals from receptors, so this cannot have been responsible for the illusion,' says Dr Janet Taylor, one of the authors of the paper. The experiment provides a new and intriguing illusion that sheds light on h...

MIT: Oceans are a major gene swap-meet for plankton

...there's a constant shuffling of genetic endowments going on among tiny plankton, and the "coinage" they use seems to be a flood of viruses, MIT scientists report. The research, led by MIT Professor Sally W. Chisholm, is uncovering a challenging new facet of evolution, helping scientists see how photosynth...

Environmental metagenomics diagnosing extreme environments, tapping opportunities for clean energy

... hydrogen as a byproduct. "It's not as if we are going to put termites in our tank, but if we can harness the termite microbe enzymes that breakdown lignocellulose and make hydrogen, we may end up with a commercially viable process," says Rubin. ...

World faces challenge as life expectancies lengthen, scientist says

...tween the world's rich and poor. "Are some people going to be left behind? Are we going to make society far more unequal than it is now?" he asked. Tuljapurkar predicted that the lifespan ...

Natural selection at single gene demonstrated

...under selection. I think a lot of that research is going to end up in the trash can," Nordborg said. The group's method can be applied to any organism, including humans. The PLoS paper focused on the weed Arabidopsis thaliana, and in particular on the FRIGIDA (FRI) gene, known to influence flowering tim...

Ernst Mayr's theory illustrated in genetic epidemiology studies

... of these genes through some random factor, you're going to have a tremendous shift in where natural selection is directed in a genetic sense," he said. "This is the underlying basis of genetic revolution. We have documented that a gene major in one population is minor in another. This is a very real ph...

Marine mammals are on the frontline of failing ocean health

Scientists discover interplay between genes and viruses in tiny ocean plankton

...s there's a constant shuffling of genetic material going on among the ocean's tiny plankton. It happens via ocean-dwelling viruses, scientists report this week in the journal Science. Conducted by biological oceanographers Sallie Chisholm and her colleagues at the Massachusetts Institute of Technology, th...

A link is found between morphine addiction and the tendency to explore

...eful in prevention campaigns for children, who are going through the period with the highest risk," explains Doctor Nadal. To determine a rat's level of addiction to morphine, the researchers used the place-conditioning technique. In these tests, a special cage is used that has two very different compartm...

Great (taste) expectations: Study shows brain anticipates taste, shifts gears

...dict the subject's perception of what the taste is going to be. The subject anticipates that the taste won't be that bad, and indeed that's what they report." In short, the new study shows how expectancy affects how humans perceive sensory input, and how events in the brain are directly related to those p...

Climate change: The rice genome to the rescue

...es decreasing yields. "Clearly, climate change is going to have a major impact on our ability to grow rice," Robert S. Zeigler, IRRI director general, said. "We can't afford to sit back and be complacent about this because rice production feeds almost half the world's population while providing vital empl...

Pair of studies offer new clues to combat antibiotic resistance

...tibiotic resistance is a huge problem that is only going to get worse. We need new targets, especially if we’re going to circumvent resistance," Walker says. Both research teams caution that these new approaches may b...
