CU study reveals why starling females cheat

...hat males of many species cheat and mate widely to produce as many offspring as possible to spread their genes, the reasons behind female infidelity appear more complex. With this study and this species, "we can break down the reasons why superb starling females are not faithful to their mates and see that t...

The mouflons of the Kerguelen archipelago

... decreases. Furthermore, consanguinity is known to produce genetic diseases. The most heterozygous individuals are better able to resist these diseases,” explains Renaud Kaeuffer. The researchers stress the point that the genetic variety of the mouflons on the Kerguelen Islands is still less than what could ...

Turn-ons and turn-offs for neurons

...n the adult brain can be avoided by making neurons produce high levels of gene-specific activators which facilitate “un-silencing” of previously silenced genes. These findings have important implications in experimental research that makes use of reversible gene expression tools to switch genes on and off. N...

Putting feelings into words produces therapeutic effects in the brain

...the present moment, without distraction — seems to produce a variety of health benefits. When people see a photograph of an angry or fearful face, they have increased activity in a region of the brain called the amygdala, which serves as an alarm to activate a cascade of biological systems to protect the ...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

... The genome sequence is peppered with genes that produce enzymes to digest proteins and other animal material in the soil. Also found, uniquely in this species, is a range of genes that allow it to attack the many insect and other small creatures that live in the soil. The ‘chitinases’ produced by these ge...

For many insects, winter survival is in the genes

...s. Insects and other animals, including humans, produce heat-shock proteins in response to extremely high temperatures. The proteins are so named because they were initially discovered in fruit flies that were exposed to high heat. Humans make these proteins when we run a high fever. "But insects make ...

Smallpox outbreak: How long would it take for vaccines to protect people? Would it work?

...vestigational smallpox vaccine called IMVAMUNE® to produce a strong immune response against smallpox disease with another vaccine called Dryvax®, the currently licensed vaccine. The new vaccine will be given either alone or in combination with Dryvax. "Another purpose of the study is to see how quickly p...

Early exposure to indoor fungus molecules may protect infants against future allergies

... glucans—can stimulate the body’s immune system to produce infection- and allergy-fighting substances. Because of this, Iossifova says, people should avoid overusing antibacterial sprays and soaps to clean their bodies and homes. "Certain microbes can have helpful affects in the body," she explains, "but ...

pHLIP, a novel technology to locate and treat tumors

...ion to targeting tumors, other disease states that produce inflammation and cause tissue to be acidic are a target for pHLIP. “Acidosis is a physiological marker of many diseases ?and pHLIP feels acidity,?said Reshetnyak. “Therefore, pHLIP could also be used for monitoring of disease development and therape...

Scientists discover rare 'gene-for-gene' interaction that helps bacteria kill their host

Novel system developed to turn data into real-time, interactive 3-D images

...arge 3- and 4-D data sets. The new technology will produce a 3-D, high quality, real-time image of the data to help physicians and other medical professionals more clearly view, and rapidly extract important diagnostic information about, the body’s structures or disease processes. The new system will be ...

Corals -- More complex than you?

...al genes. However corals use all those genes to produce only 12-14 types of body cells. Humans, on the other hand, have developed hundreds, even thousands of different cell types. A possible explanation for this, Prof. Miller believes, is that coral genes may interact with each other in far less compl...

I’m pretty optimistic that it will work in living subjects." The leader of the student design team, Tom Link, said he selected ...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...e 13. Several other genes detected in the study produce proteins involved in this and other biochemical pathways thought to play a role in bipolar disorder. Understanding the effects that variations of these genes have on brain-cell function could lead to explanations of how they contribute to the condit...
