Salk researchers find new drug target for lung cancer

Drugs targeting an enzyme involved in inflammation might offer a new avenue for treating certain lung cancers, according to a new study by scientists at the Salk Institute for Biological Studies.

The scientists discovered that blocking the activity of the enzyme IKK2, which helps activate the body's inflammation response, slowed the growth of tumors in mice with lung cancer and increased their lifespan.

Old antibiotic could be a new weapon to fight TB

A cheap and safe antibiotic that is widely available in the developing world might have a new use as a tuberculosis (TB) treatment, according to new research.

Building Blocks of Early Earth Survived Collision that Created Moon

Unexpected new findings by a University of Maryland team of geochemists show that some portions of the Earth's mantle (the rocky layer between Earth's metallic core and crust) formed when the planet was much smaller than it is now, and that some of this early-formed mantle survived Earth's turbulent formation, including a collision with another planet-sized body that many scientists believe led to the creation of the Moon.

Alzheimer's drugs may have adverse side effects

Alzheimer's disease drugs now being tested in clinical trials may have potentially adverse side effects, according to new Northwestern Medicine research. A study with mice suggests the drugs could act like a bad electrician, causing neurons to be miswired and interfering with their ability to send messages to the brain.

Multi-modal EEG analysis of newborns show how brain tracts are formed

In the past few years, researchers at the University of Helsinki have made several breakthroughs in discovering how the brain of preterm babies work, in developing treatments to protect the brain, and in developing research methods suitable for hospital use.
