Two brain systems tell us to breathe

Until now, scientists believed that a single area in the brain generated breathing rhythm, enabling breathing to speed up or slow down to adapt to the body’s activity and position. But UCLA neurobiologists have discovered that two systems in the brain interact to generate breathing rhythm — a finding that may translate into better treatment for sleep apnea and sudden infant death syndrome. The journal Neuron reported the findings in its March 6 issue.

“We originally thought that only one bra

New hope for correcting irregular heartbeat

Robert Wood Johnson University Hospital expands treatment options

People who suffer from irregular heartbeat now have a different treatment option, thanks to a new procedure being offered at Robert Wood Johnson University Hospital.
RWJUH is the first hospital in New Jersey and one of a few centers in the nation to offer patients the option of Microwave Ablation as a stand-alone procedure to eliminate atrial fibrillation, the most common form of irregular heartbeat.

Myosin V, The Molecular Motor, Moves in ’Monkey-Bar’ Motion

Unique Hand-Over-Hand Rotation Transports Molecules Through Cells

Within every neuron is a vast protein trail system traversed by a small protein engine called Myosin V. The long-standing question of how this molecule moves may have finally been resolved by researchers from the University of Pennsylvania School of Medicine. Their findings, presented in this week’s issue of Nature, show how myosin V can move ’hand-over-hand’ on tracks, composed of a protein called actin,

It takes two to fight cancer

New research at the Institute of Food Research shows that two food components recognised for their ability to fight cancer are up to 13 times more powerful when put to work together. The results are published in the latest issue of international journal Carcinogenesis.

The study focuses on genes that play an important role in tumour formation, tumour progression, and the spread of tumour cells. The food components sulforaphane and selenium were found to have an increased impact on these gene

Sunquakes Reveal The Solar Furnace

Most people are familiar with the fact that sensitive instruments known as seismographs can detect earthquakes taking place many hundreds or thousands of miles away. By studying the waves from these tremors, scientists can find out about the conditions deep inside our rocky planet.

In the same way, astronomers are now able to measure millions of sound waves that propagate throughout the Sun, causing it to vibrate or ring like a bell. This technique, known as helioseismology, is the solar eq

Researchers Say Deadly Twist Key To Sickle Cell Disease

Patients with sickle cell disease have mutant haemoglobin proteins that form deadly long, stiff fibres inside red blood cells. A research team led by University of Warwick researcher Dr Matthew Turner, propose a mathematical model in the 28 March online issue of PRL to explain the persistent stability of these deadly fibres. The theory suggests that an inherent “twistiness” in the strands that make up the fibres could be the key to their durability and possibly to new treatments.
