Research casts doubt on circulating stem cells

...rain where they do not change into nerve cells but blend with the neurones that already exist there." In this case, the presumed stem cells would only have coloured a few brain cells green. ...

Male elephants woo females with precise chemistry

The exact chemical blend of a pheromone emitted by older male elephants in musth influences both a female elephant's interest in mating and how other surrounding elephants behave, a new study has found. The researchers at Oregon Health & Science University and the Univ...

New nanosensor uses quantum dots to detect DNA

...and mutations." The technique involves an unusual blend of organic and inorganic components. "We are the first to demonstrate the use of quantum dots as a DNA sensor," Wang said. Quantum dots are crystals of semiconductor material, whose sizes are only in the range of a few nanometers across. (A nanomet...

Purdue creates new low-cost system to detect bacteria

... squares and triangles, but each face has a unique blend of these shapes. We did something similar. We reduced complicated scatter patterns to 120 numbers based on Zernike polynomials." This reduced collection of numbers describes how well the colony fits the template, and then pattern recognition softwa...

Robots manipulating animal behaviour

... they are real creatures. The roach pheromones ?a blend of molecules developed by the project partner from the Université de Rennes I, France ?enable various forms of communication, including recognition and attraction. For example, when a roach detects another roach, it may approach it, move away or stop...

Gene therapy research switches off joint inflammation; switches on genetic process of joint repair

...the Inflammation Research Association (IRA) that a blend of natural botanical products called Reparagen have turned on the master repair gene, IGF-1, which is responsible for growing human cartilage and restores joint function while blocking joint destruction associated with inflammation. The IRA is the pr...

Selecting life: Scientists find new way to search for origin of life

...origins research, therefore, is how just the right blend of critical biomolecules was selected, concentrated, and organized from the diverse primordial "soup." Previous research by the Carnegie team and others has shown that many molecules, including amino acids, can adhere to mineral surfaces, prompting f...

Nanotextured implant materials: blending in, not fighting back

...ysical structure to allow the foreign materials to blend in better. "What we're trying to do is fundamentally different," says Webster. "We're trying to find materials that the body accepts, rather than develop drugs or develop materials that will kill a cell ?no matter if it kills a bad cell or a good cel...

Get a whiff of this: Smell test could sniff out serious health problems

...ys the test subjects get a whiff of three odors: a blend of ripe cheese and rancid meat, a fragrance that combines a burning smell with a skunk-like smell, and amyl acetate, which smells like banana. “You have to get people to really suppress the sniff and that’s why the bad odors work so well,?explains Fr...
