Choosy females make colourful males

...n Lake Victoria cichlid fish, Martine Maan found a solution for this paradox: in different species, different traits reveal male quality. She examined two closely related species, one with blue males and the other with red males. Females prefer males of the right colour, blue or red, and within those catego...

Einstein researchers take the pulse of a gene in living cells

...teful and would overheat the house," he says. "The solution is a thermostat, which injects a little bit of hea...ctivity at the wrong time can be a problem, so the solution is to have small bursts of activity." Still to be discovered, says Dr. Singer, is how the pulsing m...

Producing bio-ethanol from agricultural waste a step closer

...ity of Technology, however, has recently devised a solution for this, which is achieved by genetically modifying the baker's yeast. The Delft researchers have inserted a gene (derived from a fungus that is found in elephant faeces) into baker's yeast, allowing it to convert an important sugar type, xylose, in...

Nanosecond-scale release of stinging jellyfish nematocysts

...mer of the nematocyst capsule wall. This ingenious solution allows the cellular process of vesicle exocytosis to release kinetic energy in the nanosecond range by a powerful molecular spring mechanism. ...

Weizmann Institute scientists discover a molecular security mechanism for keeping mutations in check

...s to be carried over in cell division. The body's solution to minimizing mutations is to have no fewer than ten different "careless" enzymes. Although this may seem paradoxical ?intuitively, more careless enzymes should mean more mutations ?each of these enzymes is tailored to deal with certain specifics typ...

How the US drug safety system should be changed

...nt system of drug-safety monitoring and proposes a solution that addresses overly aggressive early marketing practices; an absence of incentives to complete post-marketing safety studies; direct-to-consumer (DTC) advertising that can promote non-critical use of "blockbuster" drugs; the current trend toward de...

Fat stem cells being studied as option for breast reconstruction

...- or fat-derived stem cells may represent a better solution for soft tissue reconstruction in breast cancer patients," said Dr. Rubin, who also is co-director of the Aesthetic Surgery Center at the University of Pittsburgh Medical Center. The use of stem cells to treat disease or regenerate tissue is belie...

Stormy days ahead for coral reefs

... these vulnerabilities." "Our study offers a solution to this longstanding problem by factoring in the shape of different coral colonies, the strength of the sea-bed to which they attach and the change in force of the waves as they move across the reef. "This enables us to predict the likely change...

Plutonium or greenhouse gases? Weighing the energy options

..."Usually when people talk about nuclear power as a solution for global warming, the issues of nuclear waste and weapons proliferation are footnotes in the discussion," said Ewing, who is the Donald R. Peacor Collegiate Professor and Chair in the U-M Department of Geological Sciences and also has faculty appoi...

Different strategies underlie the ecology of microbial invasions

...ce competition from other lineages. One widespread solution is to kill these competitors. In the new work, the researchers explored the relative value to both invading and defensive bacteria of two distinct microbial mechanisms of killing competitors: through the release of chemicals (for example, antibio...

Like a snail through the intestinal canal

... would cause the intestine to become deformed. The solution then is found in using smaller and larger surfaces that slide over each other. If a large surface coated with muco-adhesive remains still, and a relatively small surface coated with muco-adhesive begins moving in relation to the larger surface, the ...

Wheat gene may boost foods' nutrient content

... iron content in the grain, potentially offering a solution to nutritional deficiencies affecting hundreds of millions of children around the world. Results from the study will be reported in the Nov. 24 issue of the journal Science. "Wheat is one of the world's major crops, providing approximately one-fif...

Coral reefs are increasingly vulnerable to angry oceans

...cording to the researchers. "Our study offers a solution to this longstanding problem by factoring in the shape of different coral colonies, the strength of the sea-bed to which they attach, and the change in force of the waves as they move across the reef," said Madin. "This enables us to predict the like...

Psst! Coffee drinkers: Fruit flies have something to tell you about caffeine

...eceptor protein Gr66a consumed the bitter caffeine solution to the same extent as the sugar-only solution. Montell and colleagues conclude that Gr66a is crucial for the normal caffeine avoidance behavior and without it, flies are seemingly indifferent to the bitter taste. The researchers went on to examine ...

Emergency contraception fails to halt abortions
