Detecting tiny twists with a nanomachine
A Boston University-led research team has developed a nanoscale spin-torsion oscillator that can measure miniscule amounts of twisting or torque in a metallic nanowire.

Substance tackles skin cancer from 2 sides
By playing it safe and using a two-pronged attack, a novel designer molecule fights malignant melanoma.

The US health-care crisis -- more family doctors desperately needed
The US desperately needs to increase its numbers of family doctors to improve patients' care and reduce their costs, particularly for those most vulnerable in society.

New method provides panoramic view of protein-RNA interactions in living cells
Scientists have developed a genome-wide platform to study how specialized proteins regulate RNA in living, intact cells.

Nature study demonstrates that bacterial clotting depends on clustering
Bacteria can directly cause human blood and plasma to clot -- a process previously thought to have been lost during vertebrate evolution.

MIT: Mending broken hearts with tissue engineering
Broken hearts could one day be mended using a novel scaffold developed by MIT researchers and colleagues.

Earliest known Hebrew text in Proto-Canaanite script discovered in area where David slew Goliath
The earliest known Hebrew text written in a Proto-Canaanite script has been discovered by Hebrew University archaeologists in an ancient city in the area where David slew Goliath -- the earliest Judean city found to date.

A double-barreled immune cell approach for neuroblastoma
Adding an artificial tumor-specific receptor to immune system cells called T-lymphocytes that target a particular virus extended and improved the cells' ability to fight a form of childhood cancer called neuroblastoma, said researchers form Baylor College of Medicine and Texas Children's Hospital in a report that appears online today in the journal Nature Medicine.

Persistent bacterial infection exploits killing machinery of immune cells
A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them.

Human genes sing different tunes in different tissues
Scientists have long known that it's possible for one gene to produce slightly different forms of the same protein by skipping or including certain sequences from the messenger RNA.
