The fossil record tells us about ancient life through the preserved remains of body parts like bones, teeth and turtle shells. But how to study the history of soft tissues and organs, which can decay quickly, leaving little evidence behind? In a new study, scientists use gene expression patterns, called...

Recently, a group of 23 science and policy experts from the U.S. and Canada published a review of mining risks to watersheds ranging from Montana to British Columbia and Alaska. The paper brought together experts in salmon ecology, watershed science, mining impacts and mining policy to integrate knowledge across research...

Using high quality molecular data, researchers have re-investigated a long-standing question about the position of two phyla of small aquatic invertebrates -- Kamptozoa and Bryozoa -- on the evolutionary tree.

DNA testing reveals that the wild ancestors of the common domestic and feral pigeons, now extinct in many parts of the world, are still living on islands in Scotland and Ireland.

A 15-year study details the origins and diversity of every known mineral on Earth, a landmark body of work that will help reconstruct the history of life on Earth, guide the search for new minerals and ore deposits, predict possible characteristics of future life, and aid the search for habitable...

The crystal structure of a human endogenous reverse transcriptase has similarities to HIV reverse transcriptase, a well-known tractable drug target, which will help design drugs to treat cancer and other diseases, according to a study co-authored by a Rutgers researcher.

Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leading aviation and rocket fuels, JetA and RP-1.

Researchers have created artificial Hox genes -- which plan and direct where cells go to develop tissues or organs -- using new synthetic DNA technology and genomic engineering in stem cells. Their findings confirm how clusters of Hox genes help cells to learn and remember where they are in the...

Researchers have discovered that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.

New research using computer simulations and Hollywood-style motion capture shows how birds optimize their landing maneuvers for an accurate descent.
