Fitness has fallen since the days of Ancient Greece

We may not be as fit as the people of ancient Athens, despite all that ... the trireme or they would have to be an extremely fit group. Our data raise the interesting notion that these ancient athletes were genetically better ada...

New player in commitment to life as a fat cell

... that XOR was at the top of the list of genes that fit the profile of a fat generator. Indeed, they found evidence that XOR controls PPAR-gamma a transcription factor considered to be the master regulator of fat production since it is both necessary and sufficient for adipose differentiation both in v...

UC Davis researchers use heated nanoprobes to destroy breast cancer cells in mice

...ed trillions of the probes -- more than 10,000 can fit on the end of a straight pin -- into the bloodstreams of laboratory mice bearing human breast tumors. Once in the bloodstream, the probes began to seek out and latch onto receptors on the surface of malignant cells. Three days later, the team appl...

BMI not accurate indicator of body fat

...r percent fat, even though body fat doesn't really fit into the equation. "What if you take fat out of the equation?" he said. "Is there something unique about BMI that may increase a person's risk of chronic disease, unrelated to fatness? Are people with high BMIs but low fatness as much at risk of h...

Natural antibiotics yield secrets to atom-level imaging technique

...e, rearranging parts of the molecule might make it fit into the membrane better, resulting in greater effectiveness with smaller amounts of AMP. "Our overall mission is to use the kind of basic physical data we obtain from solid-state NMR spectroscopy to help interpret biological functions," Ramamoort...

MIT's ocean model captures diversity of underwater forests

...y, then allows the ocean to self-select those most fit for survival in any particular area. What emerged after the model completed its 10-year virtual evolution -which took four to five days on a cluster of parallel computers-is a phytoplankton community with members that are characteristic of observe...

The quest for an effective HIV vaccine presents new possibilities, challenges

...ness, and how the first successful HIV vaccine may fit into a comprehensive HIV/AIDS prevention effort. Vaccines typically work by mimicking the effects of natural exposure to a specific microbe. Because of initial exposure, the immune system develops the ability to recognize the specific microbe and ...

DOE JGI sets 'gold standard' for metagenomic data analysis

...and a substantial number of sequences that fail to fit onto those larger fragments. On many occasions, this information is not taken into account, depriving the analysis of valuable information embedded in that sequence. The solution proposed by Mavrommatis and his colleagues was to evaluate and comp...

Newborn neurons like to hang with the 'in' crowd

Like any new kid on the block that tries to fit in, newborn brain cells need to find their place within the existing network of neurons. The newcomers jump right into the fray and preferentially reach out to mature brain cells that are already well connected within the established circuitry, repor...

Ants show us how to make super-highways

... matched different sizes of pot hole. Indeed, they fit beautifully", explained Franks. Overall, this behaviour results in an increase in the average speed of prey-laden traffic. Moreover, calculations suggest that under a range of realistic scenarios, plugging behaviour results in a clear increase in...

3-D ultrasound scanner provides in-depth view of the brain

...anning, the researchers shrunk it even further, to fit through a 10 millimeter hole in the skull. "The earlier device required a hole bigger than a quarter," Light said. "Now, it's closer to the size of a dime." The brain imager also required them to shift the orientation of the ultrasound beam w...

Researchers demonstrate way to control tree height

Exploring the dark matter of the genome

...y repeating sequences, typical of heterochromatin, fit together." Thus the first "substantially complete" genome sequence of Drosophila, published in Science in March, 2000 by the Berkeley Drosophila Genome Project and Celera Genomics, was actually far from complete. It left out a third or more of th...

Study shows lizard moms dress their children for success

...s and yellow sires in the experiments had the most fit progeny," Lancaster said. "But under different environments, maybe the progeny that weren't tweaked would have the highest fitness. If these same estradiol-induced types had the highest survival rates in all years, there would be no need for the fema...
