ReFIT algorithm improves speed and accuracy of neural prosthetics

When a paralyzed person imagines moving a limb, cells in the part of the brain that controls movement still activate as if trying to make the immobile limb work again. Despite neurological injury or disease that has severed the pathway between brain and muscle, the region where the signals originate remains intact and functional.

Examining private sector, foreign government involvement in Haiti's health system

With recent suggestions "of privatizing the [U.S.] government's emergency response capability for natural and human-caused disasters and infectious diseases," Henry (Chip) Carey, an associate professor of political science at Georgia State University in Atlanta, writes in the World Policy Blog, "One might want to look at Haiti for a case study in the effects of bypassing the government health sector for private organizations."

Viewpoints: Voters want Medicare protected in 'grand bargain;' Increases in taxes can't cover the 'fiscal cliff'; Kids' health needs more attention

As the ranking member on the House Financial Services Subcommittee on Domestic Monetary Policy and Technology, let me simply state the hard truth. To avoid the fiscal cliff and to get our budget deficit and the national debt under control, we need to do three things simultaneously: cut spending, increase revenue and have the courage to put everything on the table in a responsible, bipartisan manner.

Researchers sequence the DNA of 6,700 exomes of cystic fibrosis patients

A multi-institutional team of researchers has sequenced the DNA of 6,700 exomes, the portion of the genome that contains protein-coding genes, as part of the National Heart, Lung and Blood Institute (NHLBI)-funded Exome Sequencing Project, one of the largest medical sequencing studies ever undertaken.

Researchers develop new kind of intracranial pressure sensor

An increase in cerebral pressure may cause dementia and could destroy the brain. Companies have been seeking to find monitoring sensors that can be implanted into the brain, and read from outside the body. A tiny sensor may provide the help needed.

Researchers succeed in teaching computers how to identify commonalities in DNA sequences

Johns Hopkins researchers have succeeded in teaching computers how to identify commonalities in DNA sequences known to regulate gene activity, and to then use those commonalities to predict other regulatory regions throughout the genome. The tool is expected to help scientists better understand disease risk and cell development.

Viewpoints: Romney, Obama offer details of their plans; The 'passionate supply-sider' who taught Paul Ryan; Medicare plan has not 'doomed GOP'

All presidential elections matter. This one matters a great deal. It matters to the senior who needs medical care but, thanks to ObamaCare, can't find a doctor who is taking new Medicare patients. ... This election is about them. It is about all of us. ... It is about the education of our children, the value of our homes, the take-home pay from our jobs, the price of the gasoline we buy, the choices we have in our health care.

Scientists develop new micropump for hand-held medical devices

In an advance toward analyzing blood and urine instantly at a patient's bedside instead of waiting for results from a central laboratory, scientists are reporting development of a new micropump capable of producing pressures almost 500 times higher than the pressure in a car tire. Described in ACS' journal Analytical Chemistry, the pumps are for futuristic "labs-on-a-chip," which reduce entire laboratories to the size of a postage stamp.

Roundup: SCOTUS won't hear Okla. 'personhood' case; Vt. pushes state employees to use CHIP for kids coverage; N.J. hospitals want bundled payments

The Supreme Court on Monday declined to hear a case involving the anti-abortion-rights movement's push to define "personhood" in the law. By rejecting the appeal, the justices left in place a lower court's decision that found a personhood measure in Oklahoma would violate the Constitution. Only four of the nine justices have to agree for the court to take a case, so Monday's rejection could be a sign that the court's four conservative justices aren't interested in wading into personhood, a concept that has divided opponents of abortion rights.
