Too much sugar not good for coral reefs

...hates cause algal overgrowth on corals, which also contributes sugars to the system. It is vital to consider the carbon component as we develop conservation strategies for coral reefs." ...

Engineered mouse mimics cognitive aspects of schizophrenia

...ncreased activation of [dopamine] receptors indeed contributes to the cognitive deficits of patients with schizophrenia, our data could explain why antipsychotics do not greatly ameliorate cognitive deficits," wrote the researchers. "The physiological alterations that are responsible for cognitive deficits may b...

Aggression-related gene weakens brain's impulse control circuits

...tifies neural mechanisms by which this gene likely contributes to risk for violent and impulsive behavior through effects on the developing brain. NIMH intramural researchers Andreas Meyer-Lindenberg, M.D., Ph.D, Daniel Weinberger, M.D., and colleagues report on their magnetic resonance imaging (MRI) study on...

UC San Diego partners with Venter Institute to build marine microbial genomics cyberinfrastructure

...disciplines. The Moore Foundation grant, in part, contributes to the $1 billion fundraising goal of The Campaign for UCSD: Imagine What's Next. Background The goal of the CAMERA project is to create important advances in the knowledge of evolutionary biology and microbial ecology in marine and other natural...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

... cognitive loss." Knowledge that the immune system contributes to nerve cell renewal has potential far-reaching implications for elderly populations, because aging is known to be associated with a decrease in immune system function. It is also accompanied by a decrease in new brain cell formation, as well as in ...

UCLA scientists uncover mechanism of response to targeted therapy

...IF. "We theorized that by inhibiting mTOR, which contributes to HIF levels, we might be able to significantly reduce HIF and remove the growth advantage the cancer cells had," Thomas said. "Because we now know the mechanism that is fueling the growth of the cancer cells, we can identify patients who will respo...

Zebra finches remember songs dad sang

...nches, Bengalese finches and canaries. The father contributes equally to childcare in zebra finch families and does all the singing, Vicario says. "In everyday English, 'song' and 'call' mean the same thing, but in scientific language, they're different," Vicario says. "Calls communicate information about food ...

Growth factor-promoting angiogenesis expressed in tumor cells and normal neurons

...d brain injury, brain cell-mediated SCF expression contributes to tumor growth by setting up an environment that supports angiogenesis and tumor progression. The researchers demonstrate that decreased SCF expression in vivo results in decreased angiogenesis and improved survival in mouse glioma models, whereas ...

Groovy protein essential for promoting cancer development

...due telomerase, an enzyme whose excessive activity contributes to the unchecked growth of as many as 90 percent of human tumors. The enzyme is vital for some rapidly dividing cells ?such as those in a developing embryo ? where it extends telomeres, the regions of highly repetitive DNA found at the ends of chromo...

Are dancers genetically different than the rest of us? Yes, says Hebrew University researcher

...s the level of serotonin, a brain transmitter that contributes to spiritual experience, among many other behavioral traits. The vasopressin receptor has been shown in many animal studies to modulate social communication and affiliative bonding behaviors. Both are elements involved in the age-old human social exp...

Secrets of the sea yield stronger artificial bone

.... Replicating all of these scales -- each of which contributes to the overall performance of nacre -- in a synthetic substance is extremely difficult. Then, the Berkeley Lab researchers thought of sea ice. "We allow nature to guide the process. Seawater can freeze like a layered material, so why not use this p...

According to the Centers for Disease Control and Prevention Web site, antibiotic resistance is a growing threat to the general population, as well as the military. In fact, more than 70 percent of the bacteria that cause ...

Mushrooms as good an antioxidant source as more colorful veggies

...t and, even though the assay used does not show it contributes to total antioxidant activity in the mushrooms, it may significantly contribute antioxidant activity in the body." The ORAC values found in the latest study indicate that mushrooms are potent anti-oxidant sources. The research revealed that, of the ...

Bedsores and bald hides: Novel roles revealed for a 'scaffolding' protein

...ts is that the presence of K17 in these skin cells contributes to turning on the molecular pathways that lead to protein synthesis and cell growth, and this promotes timely healing of skin wounds," says Coulombe. "The capacity for wound healing decreases with age, and a better understanding of the fundamental me...
