Researchers at the University of Missouri have found a way to create radioactive nanoparticles that target lymphoma tumor cells wherever they may be in the body.

Michael Lewis, an associate professor of oncology in the MU College of Veterinary Medicine, says being able to target secondary tumors is vital to successfully treating patients with progressive cancers.

“Depending on the type of cancer, primary tumors… read more

New data show that the NeuroStar TMS (transcranial magnetic stimulation) Therapy System induced statistically and clinically meaningful response and remission in patients with Major Depressive Disorder (MDD) during the acute phase of therapy, and the effects were maintained through one year of treatment.

At the end of acute treatment, 62 percent of patients achieved symptomatic improvement while 41 percent reported complete remission. At 12 months,… read more

When did the first stars and galaxies form in the universe? How brightly did they burn their nuclear fuel?

Scientists will seek to gain answers to these questions with the launch of the Cosmic Infrared Background ExpeRIment (CIBER) on a Black Brant XII suborbital sounding rocket between 11 and 11:59 p.m. EDT, June 4 from the Wallops Flight Facility in Virginia.

Jamie Bock, CIBER principal investigator… read more

A new tumor-killer

May 23, 2013


Scientists from Nanyang Technological University (NTU) and Lund University, Sweden, have bioengineered a novel molecule proven to successfully kill tumor cells.

This molecule is based on a natural protein present in human breast milk, which has been found to have strong and wide-ranging tumor killing properties when bound to certain lipids. Lipids are organic molecules like amino acids and carbohydrates, made up of carbon and… read more

A new method for producing clean hydrogen

May 23, 2013


Duke University engineers have developed a novel method for producing clean hydrogen, which could prove essential to weaning society off of fossil fuels and their environmental implications.

While hydrogen is ubiquitous in the environment, producing and collecting molecular hydrogen for transportation and industrial uses is expensive and complicated. Just as importantly, a byproduct of most current methods of producing hydrogen is carbon monoxide, which is… read more

Scanadu has announced updates to its Scanadu Scout, the “first medical Tricorder,” a prototype device designed to measure vital signs; and the launch of an indiegogo campaign.

A first-edition Scout can be reserved on indiegogo and will be available in March 2014.

The Scout is sold as an exploratory tool. “By helping us collect data, we can file our application to the FDA for market… read more

Stephen Hawking’s life: a comic book

Released May 23, “Stephen Hawking: Riddles of Time & Space” is an illustrated version of Hawking’s life story in comic-book form.

“The most surprising thing about Stephen Hawking is his razor wire wit that is sometimes withering and other times matched with a puckish sense of humor. He maintains a child’s delight in discovery and credits his disability for allowing him to focus his mind.

“Our… read more

Russia developing anti-terrorist robots

May 23, 2013


Russian experts are developing robots designed to minimize casualties in terrorist attacks and neutralize terrorists, Russian Deputy Prime Minister Dmitry Rogozin said on May 17, RIA Novosti reports.

Robots could also help evacuate injured servicemen and civilians from the scene of a terrorist attack, said Rogozin, who oversees the defense industry.

Other anti-terror equipment Russia is developing includes systems that can see terrorists through obstacles and… read more

Instead a carrying spare parts, space-constrained U.S. Navy ships in the future might carry 3-D printers and bags of various powdered ingredients, and simply download the design files needed to print items as necessary, according to the Armed Forces Journal,

“Perhaps closer at hand is a distributed global production network in which sailors and Marines send an email with a digital scan or design for a

Waterproof fabrics that whisk away sweat could be the latest application of microfluidic technology developed by bioengineers at the University of California, Davis.

The new fabric works like human skin, forming excess sweat into droplets that drain away by themselves, said inventor Tingrui Pan, professor of biomedical engineering.

One area of research in Pan’s Micro-Nano Innovations Laboratory at UC Davis is a… read more

Do salamanders hold the solution to regeneration?

May 22, 2013


Salamanders’ immune systems are key to their remarkable ability to regrow limbs, and could also underpin their ability to regenerate spinal cords, brain tissue and even parts of their hearts, scientists have found.

In research published in the Proceedings of the National Academy of Sciences (open access), researchers from the Australian Regenerative Medicine Institute (ARMI) at Monash University found that when immune cells known as macrophages… read more

Activating an enzyme known to play a role in the anti-aging benefits of calorie restriction delays the loss of brain cells and preserves cognitive function in mice, according to a study published in the May 22 issue of The Journal of Neuroscience.

The findings could one day guide researchers to discover drug alternatives that slow the progress of age-associated impairments in the brain.… read more

Researchers in the Optical and Quantum Communications Group at MIT’s Research Laboratory of Electronics (RLE) have experimentally demonstrated a new quantum communication protocol that solves two basic problems with achieving practical quantum encryption.

Quantum key distribution (QKD) requires the inefficient transmission of a huge number of bits for each one that’s successfully received. And QKD depends on the properties… read more
