Mechanism in newborn's memory centre that adjusts brain maturation for information processing discovered

With their French colleagues, researchers at the University of Helsinki have found a mechanism in the memory centre of newborn that adjusts the maturation of the brain for the information processing required later in life. The study was published this week in an American science magazine The Journal of Neuroscience.

World Science Festival announces 2010 Kavli Prize laureates

The World Science Festival launches its first full day with the announcement of the 2010 Kavli Prize laureates. This event will feature a keynote address by Harold Varmus, co-chair of President Obama's Council of Advisors on Science and Technology, as well as a live simulcast of the announcement of the laureates by the Norwegian Academy of Science and Letters from Oslo, Norway.

Oxygen levels induce X chromosome inactivation in female cells: Study

Oxygen levels in the lab can permanently alter human embryonic stem (ES) cells, specifically inducing X chromosome inactivation in female cells, according to Whitehead Institute researchers. Human ES cells have been routinely created and maintained at atmospheric levels of oxygen, which is about 20%. Cells in the body are usually exposed to only 1-9% oxygen.

Revolutionary technology to protect skin stem cells and combat chronological aging

Emerge Labs presents a revolutionary technology that protects skin stem cells and combats chronological aging. The breakthrough patent-pending active ingredient, PhytoCellTec Solar Vitis, boosts the production of human skin stem cells, protects human skin stem cells against UV radiation, and fights photo-aging, thus decreasing wrinkles and producing younger, fresher looking skin.

Male physical competition central in winning mates among human ancestors: Penn State

Male physical competition, not attraction, was central in winning mates among human ancestors, according to a Penn State anthropologist.

New way to coax embryonic stem cells and reprogrammed adult cells to develop sensory cells

After ten years of effort, researchers reporting in the May 14th issue of the journal Cell, a Cell Press publication, say they have found a way to coax embryonic stem cells as well as reprogrammed adult cells to develop into sensory cells that normally reside in the mammalian inner ear. Those mechanosensitive sensory hair cells are the linchpin of hearing and balance.

Measuring gene expression in healthy women may predict future breast cancer risk, say scientists

Researchers at Georgetown Lombard Comprehensive Cancer Center have been able to show, in mice, how just a little adjustment in the expression of two common genes can promote the kind of cellular changes that led to breast cancer. They say these tweaks likely mimic natural variation women have in expression of the two genes.

Tiny cell bricks hold potential for building artificial tissue

Tissue engineering has long held promise for building new organs to replace damaged livers, blood vessels and other body parts. However, one major obstacle is getting cells grown in a lab dish to form 3-D shapes instead of flat layers.

Study examines impact of tobacco smoke carcinogen on mice

Although tobacco use is widely understood to be one of the leading causes of oral cancer, research on the prevention of tobacco-related oral cancer in experimental animals has traditionally been limited to examining the impact of synthetic carcinogens manufactured especially for cancer research, rather than on observing the effects of carcinogens that occur in tobacco smoke.

Researchers determine how cells regulate chromosome/microtubule interface

Whitehead Institute researchers have determined a key part of how cells regulate the chromosome/microtubule interface, which is central to proper chromosomal distribution during cell division.

Stanford researchers make hair-cell-like cells in a petri dish

Deep inside the ear, specialized cells called hair cells detect vibrations in the air and translate them into sound. Ten years ago, Stefan Heller, PhD, professor of otolaryngology at the Stanford University School of Medicine, came up with the idea that if you could create these cells in the laboratory from stem cells, it would go a long way toward helping scientists understand the molecular basis of hearing in order to develop better treatments for deafness.

Each melanoma cell capable of cancer stem cell behavior: Study

Scientists at The Wistar Institute offer a new explanation for the persistent ability of melanoma cells to self-renew, one of the reasons why melanoma remains the deadliest form of skin cancer. The concept of the "dynamic stemness" of melanoma can explain why melanoma cells behave like both conventional tumor cells and cancer stem cells.
