Researchers think pink to produce 'green' solar energy

Researchers at Ohio State University have developed new pink dye-sensitized solar cells with half the efficiency of commercially available silicon-based solar cells, but at one quarter of the cost. The new materials use complex metals and novel particle shapes to boost electricity production.

Breakthrough for treatment of fatal heart condition

Researchers at the University of Leeds have discovered a mechanism to prevent cardiac hypertrophy by increasing the levels of REST protein, halting the progression of the fatal heart condition. This finding offers a new approach to treating the cause of heart hypertrophy rather than its symptoms.

An apple peel a day might keep cancer at bay

Cornell researchers identified a dozen triterpenoids in apple peel with potent anti-proliferative activities against human liver, colon, and breast cancer cells. The compounds may be responsible for the anti-cancer properties of whole apples.

FSU engineering professor growing bone in a lab

A FSU engineering professor is developing technologies to generate bone cells in a lab that can be transplanted into human patients. The goal is to replace lost bone mass due to osteoporosis and treat traumatic injuries. Research has shown promising results, but significant hurdles remain before the technology is ready for medical use.

Cornell robot discovers itself and adapts to injury

A Cornell-built robot learns its own model of itself and can revise the model to adapt to injury, a process resembling human and animal babies discovering their bodies. The underlying algorithm could be applied to build more complex robots and allow them to adapt to changes in environment and repair themselves.

In early embryos, cilia get the message across

Researchers at the Salk Institute discovered a non-structural gene, duboraya, that influences cilia function and regulates left-right patterning in zebrafish embryos. The gene's activation by Wnt signaling pathway helps create a counterclockwise flow necessary for establishing left versus right asymmetry.

Brown engineers build a better battery -- with plastic

Researchers have developed a hybrid battery that combines the power of a capacitor with the storage capacity of a traditional battery. The device, made from plastic and polypyrrole, has twice the storage capacity of an electric double-layer capacitor and delivers over 100 times more power than a standard alkaline battery.

Training benefits brains in older people, counters aging factors

The study found that training increases neural activation in areas associated with executive control, countering the idea that opposite brain areas compensate for cognitive decline in aging. Older adults who received training showed increased activity in brain regions tied to scheduling and planning, similar to younger participants.

Fitness counteracts cognitive decline from hormone-replacement therapy

A new study reveals that high fitness levels can enhance the effects of short-term hormone treatment and offset declines associated with long-term use. Researchers analyzed brain tissue volume in 54 postmenopausal women and found a significant association between higher fitness levels and greater tissue volume in key areas.

New microprinting technique improves nanoscale fabrication

Researchers at Penn State have developed a new microprinting technique called microdisplacement printing, which enables precise placement of molecules during nanoscale component fabrication. This method relaxes requirements for positioning stamps used to apply consecutive patterns with different molecular inks.
