Diatom genome reveals key role in biosphere's carbon cycle

...l pathways they use to metabolize their fats helps explain the ability of diatoms to withstand long periods with little sunlight--even to overwinter--and then start growing really rapidly once they return to sunlight," she says. Three or four microns in width--as many as 70 could fit in the width of a human...

Don't stand so close to me: A new view on how species coexist

...ch are not filled by others. They suggest this may explain the great diversity of wasps seen in nature. "There is a fixed amount of difference necessary," says Dr Bonsall. "This allows evolution to affect patterns of diversity such as how many similar species we see." Dr. Vincent Jansen, author of the paper ...

...ve been through a lot with the doctor. The authors explain that there are two major paths to patients valuing continuity of care: 1) if they patient and physician have been together for a long time and 2) if the patient and physician have been together through major life events such as a serious illness, hos...

Biologists ID molecular block for social 'cheaters'

...fficult adaptations for evolutionary biologists to explain because competition for resources inside the collective should lead to evolved traits that allow individuals to "cheat" the collective, win more resources and reproduce faster than their more cooperative neighbors -- thus undermining the social colle...

Study in Royal Society journals presents evidence for inherited factors in homosexuality

...authors here argue genetic factors could partially explain male homosexuality, and propose a paradox solution: genetic factors favouring homosexuality in males could increase fecundity in females, recovering the loss of fitness. They suggest these factors should be partly bound to the X chromosome, because m...

Flies have morning and evening clocks

...ity at night," he said. "There are several ways to explain that, but one possibility was that there were two clocks running -- one governing the morning peak and one governing the evening peak." Rosbash and his colleagues theorized that if dual circadian clocks existed, they would likely occupy different an...

Scientists explain how morphogens work

... considered and tested several theories that could explain how morphogens work. These theories include extracellular diffusion and transcytosis. In extracellular diffusion, it is suggested that morphogens move across cells by traveling across the surface of cells. Alternatively, the transcytosis model propos...

Normal cells in tumors may aid cancer growth

...in tumor development." The findings might help explain why tumors often behave differently, and respond differently to treatment, in people with seemingly identical cancers. The genetic changes in stromal cells also may provide new targets for future anti-cancer drugs and present a new strategy for treat...

Consuming fruits and vegetables lowers risk of developing NHL

...s and fruits contain many other nutrients that may explain the association with NHL. "Dietary modifications such as eating more vegetables and fruits are within the public's grasp to lower their risk of cancer and other diseases. We hope that these findings, in conjunction with continued re...

Dr. Harris receives NIH Javits Neuroscience Investigator Award

...hose steps. "Right now, we only know that it would explain the amount of LTP that we get in the cell." The Javits Award will enable study of the cellular mechanisms of learning and short-term memory in living laboratory animals to see whether what they have found in brain slices translates to an i...

Gene linked to greater risk of heart disease in type 2 diabetes

...s Center have found variations in a gene that help explain why people with type 2 diabetes are at much greater risk for coronary artery disease, the leading cause of death for this group. "We now have potential gene markers to help identify diabetes patients at increased risk for heart disease," said Alessan...

Genetic data crunching achieves milestone at Stanford

...," Ball said. "In fact, if you're not, you have to explain why." It's not only a result of Stanford's long history with microarrays, she said. "Anyone on campus was able to walk in and ask a postdoc in the Brown-Botstein lab, 'Can you please help me get this started in my lab?'" she explained. "Just having a...

International human genome sequencing consortium describes finished human genome sequence

The molecular biology of the sense of smell was just recognized by the awarding of a Nobel Prize in Physiology or Medicine to Richard Axel a...

The mutation could, for example, link hypertension to the age-related decline in mitochondrial function, which was identified by Shulman. Lifton has no illusions that defining the mechanisms under...

Reductions in blood oxygen levels in newborns could contribute to ADHD development

...ns and therapies." "Our research also could help explain why amphetamines, such as Ritalin, and other non-amphetamines, such as Wellbutrin, that increase levels of brain dopamine are an effective treatment for children with ADHD," Dr. Decker said. "So far scientists haven't sorted out which neurotransmitt...

Calorie restriction leads to some brain benefits but not others in mice
