Scientists show that a microRNA can reduce lung cancer growth 
A small RNA molecule, known as let-7 microRNA (miRNA), substantially reduced cancer growth in multiple mouse models of lung cancer, according to work by researchers at Yale University and Asuragen, Inc., published in the journal Cell Cycle.

Stanford researchers unmask proteins in telomerase, a substance that enables cancer
A protein conglomerate called telomerase, has in its short history been implicated in some critical areas of medicine including cancer, aging and keeping stem cells healthy. With such a resume, telomerase has been the subject of avid interest by basic scientists and pharmaceutical companies alike, so you'd think at the very least people would know what it is.

Mantis shrimp vision reveals new way that animals can see
Mantis shrimp can see the world in a way that had never been observed in any animal before, researchers report in the March 20th Current Biology, a Cell Press publication. The discovery—which marks the fourth type of visual system—suggests that the ability to perceive circular polarized light may lend mantis shrimp a secret mode of communication.

Substantial improvement in essential cheap solar cell process
A cheap alternative to silicon solar cells can be found in dye-sensitised solar cells. This type of cell imitates the natural conversion of sunlight into energy by, for instance, plants and light-sensitive bacteria.

Neuronal regulators offer potential targets for cancer
Being too brainy can be a bad thing in a junior high cafeteria, where the social hierarchy favors other traits. "Braininess" also causes problems for cells. When a breast cell begins making the proteins normally produced in neurons, for example, it can acquire cancerous properties.

NIST finds 'metafilms' can shrink radio, radar devices
Recent research at the National Institute of Standards and Technology (NIST) has demonstrated that thin films made of “metamaterials”—manmade composites engineered to offer strange combinations of electromagnetic properties—can reduce the size of resonating circuits that generate microwaves. The work is a step forward in the worldwide quest to further shrink electronic devices such as cell phones,

Researchers discover how stealthy HIV protein gets into cells
Scientists have known for more than a decade that a protein associated with the HIV virus is good at crossing cell membranes, but they didn’t know how it worked. A multidisciplinary team from the University of Illinois has solved the mystery, and their findings could improve the design of therapeutic agents that cross a variety of membrane types.

New research provides dynamic visualization of simplest circadian clock
Scientists have acquired a more dynamic picture of events that underlie the functions of a bacterial biological clock. New research published online March 13th by Cell Press in the journal Molecular Cell, shows how the simplest organism known to have a circadian clock keeps time and may enhance our understanding of how other organisms establish and govern chronological rhythms.

New window opens on the secret life of microbes
Nowhere is the principle of "strength in numbers" more apparent than in the collective power of microbes: despite their simplicity, these one-cell organisms -- which number about 5 million trillion trillion strong (no, that is not a typo) on Earth -- affect virtually every ecological process, from the decay of organic material to the production of oxygen.

Post brain injury: New nerve cells originate from neural stem cells
Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain. However, what these ‘reactive glial cells’ in the brains of mice and men originate from, and which cells they evolve into was hitherto unknown.

Paradigm shift: Switch for programmed cell death promotes spread of glioblastoma
Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis. Therefore, tumors are often resistant to chemotherapy or radiation therapy, whose effect is based on forcing tumor cells to commit suicide.

Invasive species can produce 'hotspots of evolutionary novelty,' study shows
When exotic species invade new territory, they often present a major threat to the other plants and animals living there—that much is clear. But researchers writing in the March 11th issue of Current Biology, a publication of Cell Press, now show that, in addition to their destructive tendencies, invasive species can also have a surprisingly “creative” side.

A team of Penn State University researchers is the first to demonstrate that lipid molecules in cell membranes participate in mammals' reactions to allergens in a living cell. The finding will help scientists better understand how allergy symptoms are triggered, and could contribute to the creation of improved drugs to treat them.
