Math that powers spam filters used to understand how brain learns to move our muscles

...obability” theory called Bayesian math. Unlike conventional statistical analysis, a Bayesian probability is a subjective “opinion,” that measures a “learner’s” individual degree of belief in a particular outcome when that outcome is uncertain. The idea as applied to the workings of a brain is that each brain ...

Studies to find better ways to preserve human eggs, ovarian tissue under way

Ice Age extinction claimed highly carnivorous Alaskan wolves

..., combined genetic and chemical analyses with more conventional paleontological study of the morphology, or form, of the fossilized skeletal remains. This multifaceted approach allowed the researchers to trace the ancient wolves’ genetic relationships with modern-day wolves, as well as understand their role in th...

Modified mushrooms may yield human drugs

...potentially faster and cheaper with mushrooms than conventional technologies. Unlike plants that have long growth cycles, "with mushrooms, we can use commercial technology to convert the vegetative tissue from mushroom strains stored in the freezer into vegetative seed. A crop from which drugs may be extracted ...

Catching cancer's spread by watching hemoglobin

...latively deep tissue (up to 1 mm, much better than conventional microscopes) with a resolution at the micron scale (at the level of blood cells, which is better than MRI resolution) and does not require any contrast agents or fluorescent markers (unlike most other high-resolution vessel-imaging techniques). ...

Maggots rid patients of MRSA

...ks, much quicker than the 28-week duration for the conventional treatment. Professor Boulton, who published the results in the journal Diabetes Care, has now been awarded a £98,000 grant by Diabetes UK to carry out a randomized controlled trial to compare this treatment with two others. "Maggots are the wor...

8 plants from South Africa may hold potential for treating high blood pressure

...y was determined using rat plasma. The IC50 of the conventional ACEI, captopril was determined to test the sensitivity of the assay. At least three separate determinations were conducted for each test compound. A tannin test was only conducted on those plant extracts that exhibited over 50 percent ACE inhibition...

Scientists: As rainfall changes, tropical plants may acclimate

...se, he said. Such uniformity sharply contrasts the conventional notion that tropical plant species coexist by adopting widely different strategies to getting what they need. At least with regard to nitrogen uptake, all the Hawaiian plants acted the same -- and at the same time. " ?This does not support the ide...

Warts vaccine -- 1 of many in pipeline

...d we want to know if it improves the outcome after conventional therapy, which all patients also receive," Dr Jardine said. Trial researchers aim to use a tweaked version of Professor Frazer’s cervical cancer vaccine to treat genital warts. Professor Frazer said this vaccine could be one of the first made ...

Dinosaur hearing, listening to muscle noise, quieter cubicles

...son, this is around the upper frequency limit of a conventional telephone; humans speak at frequencies as high as 8 kHz and can hear up to about 20 kHz (2aAB2). Other papers in session 2aAB will explore how the middle ear of mammals evolved as they made the transition from water to land (2aAB3), the identificatio...

Genome of yellow fever/dengue fever mosquito sequenced

...in Science Express, the general failure to date of conventional disease prevention strategies for most mosquito-borne pathogens provides a strong incentive to explore and develop novel control strategies that efficiently disrupt the transmission cycle or enhance existing strategies. The Ae. aegypti genome sequenc...

Natural antibiotics yield secrets to atom-level imaging technique

...tides wipe out bacteria and other microbes. Unlike conventional antibiotics, which typically inhibit specific bacterial proteins, AMPs get downright physical with invaders, punching holes into their membranes. But they're selectively pugnacious, targeting microbes but leaving healthy host cells alone. "They're...

Risk of HIV transmission highest early in infection

... know it, and will probably often test negative by conventional antibody screening. Hence, we must do a much better job of identifying recently infected people if we are to be able to counsel them to modify high-risk sexual behavior and desist from transmitting the virus.? He suggested the development of affor...

Tundra disappearing at rapid rate

...ways occur gradually but can surge ahead. "The conventional thinking on treeline dynamics has been that advances are very slow because conditions are so harsh at these high latitudes and altitudes," said Dr. Ryan Danby, from the Department of Biological Sciences. "But what our data indicates is that there was...

Nanotextured implant materials: blending in, not fighting back

...compared samples of the nanostructured material to conventional titanium in mixed cell culture, they found that the nanoscale surface features encouraged endothelial cells to colonize the material and spread much faster than smooth muscle cells. Where endothelial cells established themselves, they formed a single...

Unlike conventional flu vaccines, which are developed by growing the influenza virus in hens' eggs and then administered as a weakened or killed form of the virus, DNA-based vaccines contain only portions of the influenza virus' genetic material.
