World's smallest cancer detection device

...l biomedical research, it is our intent to provide deeper understanding of the causes of cancer metastasis and migration ? knowledge that is of critical importance in the treatment and, ultimately, prevention of cancer." Dr. Condeelis has used the multiphoton confocal microscope to directly observe cellul...

New dyslexia theory blames 'noise'

...l student at USC, said the new findings point to a deeper problem - not just a visual deficit - affecting all areas of perception. Sperling said people with dyslexia appear to have shaky mental categories for the essential sounds that make up language. "It's harder to make a [language] task automat...

Extreme environment changes fish appearance

...the refuge-bred fish began to look different, with deeper bodies and smaller heads, although all the fish are pretty much the same genetically. Sean Lema, a graduate student at UC Davis, and Gabrielle Nevitt, professor of neurobiology, physiology and behavior, set out to see if environmental changes coul...

An artificial cornea is in sight, thanks to biomimetic hydrogels

...changes. Hydrogel lenses may even make their way deeper into the eye as replacements for inner-eye lenses damaged by cataracts. The researchers have filed four patents for ocular applications of the hydrogel. ...

From managing sugar to managing healing

...he wound more quickly and cells in the dermis, the deeper part of the skin, were faster in rebuilding blood vessels. In follow-up studies of human skin cells in culture, Manuela Martins-Green and colleagues explored the molecular impact of topical insulin on keratinocytes, the cells that regenerate the ep...

New sunscreen ingredient to heal sunburn and help prevent skin cancer

...sidered to be a major contributor as it penetrates deeper into the skin than UVB. "It is overexposure to UVA that causes the redness and inflammation, or erythema, associated with sunburn. "The UVA component of sunlight is dangerous as it acts as an oxidising agent that forms free radicals which trigg...

Anticipation plays a powerful role in human memory, brain study finds

...ndane recollections of everyday matters. Probing deeper into how such memories form, researchers at the University of Wisconsin-Madison have found that the mere anticipation of a fearful situation can fire up two memory-forming regions of the brain - even before the event has occurred. That means the si...

German researchers develop first non-invasive test to measure skin aging

...new laser-based technique images the fabric of the deeper layers of the skin, combining methods for imaging collagen and elastin, whose degeneration causes the appearance of wrinkles and the progressive loss of skin smoothness. The technique measures relative amounts of collagen and elastin by a single fact...

Dig deeper to find Martian life

...urrent probes is slim. Scientists will need to dig deeper and target very specific, hard-to-reach areas such as recent craters or areas where water has recently surfaced. Dr Andrew Coates, UCL Department of Space & Climate Physics, said: "This study is trying to understand the radiation environment ...

Ocean's 'twilight zone' may be a key to understanding climate change

...ten called "marine snow," supply food to organisms deeper down, including bacteria that decompose the particles. In the process, carbon is converted back into dissolved organic and inorganic forms that are re-circulated and reused in the twilight zone and that can make their way to the surface and back into...

Turtles are loyal in feeding as well as in breeding

...s remained in the same foraging grounds, moving to deeper water for the winter where they conducted dives of up to a record breaking 10.2 hours. Five females were also tracked when they nested again up to five years later and returned to the same foraging sites. Green turtles have been observed cropping ...

Nanotechnology shows promise as next wrinkle fighter

...he cosmetic marketplace because they can penetrate deeper into the skin, transporting vitamins and other compounds to plump and smooth tissue. But Ilsoon envisions thin films that can be injected beneath the thinning outer layer of the skin, the epidermis, that over time stiffens and buckles with aging, and...

Researchers discover new details about HIV-1 entry and infection

...ormally migrate out of the vaginal epithelium into deeper tissues shortly after exposure to HIV-1. The researchers found that HIV-1 simultaneously enters two different types of intraepithelial cells associated with the immune system, Langerhans cells (LC) and CD4+ T cells. However, the path of entry and ...

World's largest flower evolved from family of much tinier blooms

...sed to trace plant ancestry, the scientists delved deeper into the genome, looking at some 11,500 base pairs of DNA to determine that the giant flower's closest relatives are in the Euphorbiaceae family, many of which have blossoms just a few millimeters in diameter. "The power of nucleic acid comparisons...

New species of snapper discovered in Brazil

...ive in mangroves, then migrate to reef habitat and deeper areas as adults. "Several species spend some of their lives in these different yet connected habitats," Lindeman said. "That's why it's so important to develop integrated conservation strategies that include mangroves, deep reefs and other interde...

How fish species suffer as a result of warmer waters

...imate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is th...

Scientists discover new life in the Antarctic deep sea

...l Nature, scientists describe how creatures in the deeper parts of the Southern Ocean - the source for much of the deep water in the world ocean ?are likely to be related to animals living in both the adjacent shallower waters and in other parts of the deep ocean. A key question for scientists is whethe...
