New discovery may be breakthrough for hydrogen cars

A team of Virginia Tech researchers has discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel. This method uses abundantly available ...

Mature sperm lack intact mitochondrial DNA, study finds

New research provides insight about the bedrock scientific principle that mitochondrial DNA—the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body—is exclusively passed ...

Study reveals the dynamics of human milk production

For the first time, MIT researchers have performed a large-scale, high-resolution study of the cells in breast milk, allowing them to track how these cells change over time in nursing mothers.

Scientists unlock the secrets of a sixth basic flavor

Japanese scientist Kikunae Ikeda first proposed umami as a basic taste—in addition to sweet, sour, salty and bitter—in the early 1900s. About eight decades later, the scientific community officially agreed with him.

Rehabilitating lactate: From poison to cure

George Brooks has been trying to reshape thinking about lactate—in the lab, the clinic and on the training field—for more than 40 years, and finally, it seems, people are listening. Lactate, it's becoming clear, is not ...

Inverted polymer solar cell efficiency sets world record

(Phys.org)—For many years, researchers have strived to reach the goal of 10% efficiency for polymer-based organic photovoltaic (OPV) solar cells, a target widely considered to be the threshold for commercial applications. ...

Escherichia coli bacteria produce diesel on demand

It sounds like science fiction but a team from the University of Exeter, with support from Shell, has developed a method to make bacteria produce diesel on demand. While the technology still faces many significant commercialisation ...
