Ant’s social network similar to Facebook

(PhysOrg.com) -- A recent study in the Journal of the Royal Society Interface presents findings that show that not all ants are as social as others. Similar to your friends on Facebook, some ants communicate with only a ...

Initiating DNA repair

To find out what activates SIRT6, the researchers alternately applied chemical inhibitors to human skin cells to determine which proteins were essential in getting the gene to repair the broken DNA strands. They discovered ...

Biochemical cell signals quantified for first time

Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term "cell signaling" was coined more than 30 years ago ...

Researchers present a shiny new tool for imaging biomolecules

At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals that can mean life ...

A whiff of tears reduces male aggression, says study

Watching someone cry often evokes an emotional response—but according to a new study published Thursday, human tears themselves contain a chemical signal that reduces brain activity linked to aggression.

Breakthrough in sensing at the nanoscale

Researchers have made a breakthrough discovery in identifying the world's most sensitive nanoparticle and measuring it from a distance using light. These super-bright, photostable and background-free nanocrystals enable a ...

Worms hijack development to foster cannibalism, study finds

(Phys.org)—Conventional wisdom holds that genes determine the shape and structure (morphology) of animals, but something else may be at play. A new study shows that a roundworm (P. pacificus) regulates its offspring's morphology ...

Team 'spikes' stem cells to generate myelin

Stem cell technology has long offered the hope of regenerating tissue to repair broken or damaged neural tissue. Findings from a team of UC Davis investigators have brought this dream a step closer by developing a method ...

New double-contrast technique picks up small tumors on MRI

Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick ...
