Ultrafast lasers helping to make some of the shortest pulses of light ever seen in the UK will be at the heart of a new system to capture the movements of electrons as they whizz around the nucleus of atoms.

A UKP3.5 million research grant from the UK Research Councils’ Basic Technology Programme announced today has been awarded to a team of scientists to develop and build the first attosecond laser system capable of freeze-framing and controlling the motion of electrons.

The hormone leptin, primarily produced in fat cells, helps regulate food intake, metabolism and reproduction. It has also been shown to promote and sustain the bodys immune response by binding to T lymphocytes – the frontline cells that protect against infection.

The disease experimental autoimmune encephalomyelitis (EAE) in mice is currently used by researchers as a model of human multiple sclerosis (MS). The disease is characterized by the production of autoreactive T lymphocytes that tur

Research conducted at Ohio State University suggests that cell biologists may be exposing the cell cultures they study to too much oxygen.

This finding could have broad implications for cellular biology research, which receives billions of dollars of funding nationally, said Ohio State scientist Chandan Sen. He is the lead author of a study which suggests that cells act differently depending on how much oxygen they are exposed to, especially when it is too much.

Wheat growers turn to aerial imagery to overcome economic, environmental challenges

Today’s wheat growers face many economic and environmental challenges, but arguably their greatest challenge is the efficient use of fertilizer.

Growers need to apply nitrogen-based fertilizer in sufficient quantities to achieve the highest possible crop yields without over-applying – a situation that could lead to serious environmental effects. In wheat, a critical factor comes down to

Diabetes is a chronic metabolic disorder that afflicts 17 million people in the United States and is the fourth leading cause of death. Over 2 million patients suffer from its most severe form – childhood diabetes – also known as Type 1, juvenile or insulin-dependent diabetes. We now understand that childhood diabetes is an autoimmune illness, where the body’s own white blood cells, which normally fight infection, turn and act against the body. These white blood cells target a specific group of

A doctor gets a better view inside a patient by probing the body with CAT and MRI scanning equipment. Now, NASA meteorologists have done a kind of “full-body scan” of an evolving thunderstorm in the tropics, using advanced radar equipment to provide a remarkable picture of the storm’s anatomy. The observations are expected to help double-check satellite rainfall measurements, improve computer models of storms, and make the skies safer for airplanes to navigate.
