Nano-Bandages Used to Stop Severe Bleeding

Nano-Bandages Used to Stop Severe Bleeding

 New gauze material is infused with nanoparticles to quickly stop bleeding

Medical gauze has received its first upgrade since World War I. Chemists have infused it with nanoparticles derived from kaolin clay, which somehow give it an amazing ability to stop severe bleeding. It was developed when the Navy approached a team of inorganic chemists at the University of California Santa Barbara to solve a problem with QuikClot, a zeolite-based hemostatic agent that became way too hot and caused burns when it came in contact with water or blood. While performing blood clotting tests, they realized that kaolin clay, which has been used as a control for clotting experiments since the 1950’s, could also be used as a first aid product.

Geomagnetism Linked to Suicide

 Geomagnetism Linked to Suicide

Geomagnetism is an influential force on humanity

Scientists believe that earth’s magnetic field may be responsible for suicidal behavior among people.

Oleg Shumilov of the Institute of North Industrial Ecology Problems in Russia studied earth’s geomagnetic field from 1948 to 1997 and found three seasonal peaks, from March to May, July and October.

Insight Into Development of Alzheimer’s Disease

According to estimates there are 85,000 Alzheimer patients in our country and approximately 20,000 new cases every year. This spectacular increase is due to the increasing ageing population. Unfortunately it is still unclear precisely which ageing process forms the basis of this spectacular rise in the occurrence of the disease. VIB scientists affiliated to K.U.Leuven have discovered an important molecular link between Alzheimer’s disease and the development of the typical plaques in the brains of Alzheimer patients. This discovery is an important breakthrough in the fundamental research into the cause of Alzheimer’s disease.

The Military Plans To Regrow Body Parts

 The Military Plans To Regrow Body Parts

The US Military believes that humans will someday be able to regrow their limbs much like reptiles

The Department of Defense has announced the creation of the Armed Forces Institute of Regenerative Medicine to ‘harness stem cell research and technology… to reconstruct new skin, muscles and tendons, and even ears, noses and fingers.’ The government is budgeting $250 million in public and private money for the project’s first five years, and the NIH and three universities will be on the team.

Approaching the $100 Genome

 Approaching the $100 Genome
Threading long DNA molecules through nano-sized channels on a specially
fabricated chip could provide a cheaper way to sequence DNA.

It currently costs roughly $60,000 to sequence a human genome, and a handful of research groups are hoping to achieve a $1,000 genome within the next three years. But two companies, Complete Genomics and BioNanomatrix, are collaborating to create a novel approach that would sequence your genome for less than the price of a nice pair of jeans–and the technology could read the complete genome in a single workday.

Tiny Robotic Hand Has Strong Grip

Robotic Hand

Scientists have developed a pair of robotic hands that are both strong and sensitive

The tweezers can guide themselves to pick up and move individual cells without damaging them, and have a grip that can be as slight as 20 nanoNewtons of force. In fact, so advanced are the little grippers, that they can be hitched up to a microscope and, with the right software, function without human control. More below.
