Special E. coli bacteria produce diesel on demand

Posted: 22 Apr 2013 12:49 PM PDT

It sounds like science fiction but scientists have developed a method to make bacteria produce diesel on demand. While the technology still faces many significant commercialization challenges, the diesel, produced by special strains of E. coli bacteria, is almost identical to conventional diesel fuel and so does not need to be blended with petroleum products as is often required by biodiesels derived from plant oils.

Radioactive bacteria targets metastatic pancreatic cancer

Posted: 22 Apr 2013 12:47 PM PDT

Researchers have developed a therapy for pancreatic cancer that uses Listeria bacteria to selectively infect tumor cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue.

The human immune system in space

Posted: 22 Apr 2013 10:25 AM PDT

When the space shuttle Atlantis touched down in the summer of 2011 at Cape Canaveral, closing the book on the U.S. shuttle program, a team of U.S. Army researchers stood at the ready, eager to get their gloved hands on a small device in the payload that housed a set of biological samples. Results from studying these samples shed light on how the human immune system responds to stress and assaults while in space – and maybe here on Earth.

Can the friend of my friend be my enemy? Choice affects stability of the social network, animal study shows

Posted: 22 Apr 2013 09:29 AM PDT

Just as humans can follow complex social situations in deciding who to befriend or to abandon, it turns out that animals use the same level of sophistication in judging social configurations, according to a new study that advances our understanding of the structure of animal social networks.

Lazy eye disorder treated with video game Tetris

Posted: 22 Apr 2013 09:29 AM PDT

Scientists have used the popular puzzle video game Tetris in an innovative approach to treat adult amblyopia, commonly known as "lazy eye." By distributing information between the two eyes in a complementary fashion, the video game trains both eyes to work together, which is counter to previous treatments for the disorder (e.g., patching).

Grains of sand from ancient supernova found in meteorites: Supernova may have been the one that triggered the formation of the solar system

Posted: 22 Apr 2013 08:12 AM PDT

Scientists have discovered two tiny grains of silica (SiO2; the most common constituent of sand) in meteorites that fell to earth in Antarctica. Because of their isotopic composition these two grains are thought to be pure samples from a massive star that exploded before the birth of the solar system, perhaps the supernova whose explosion is thought to have triggered the collapse of a giant molecular cloud, giving birth to the Sun.

Honor among (credit card) thieves?

Posted: 22 Apr 2013 08:12 AM PDT

A criminologist dug into the seamy underbelly of online credit card theft and uncovered a surprisingly sophisticated network of crooks that is unique in the cybercrime domain.

Long-lost giant fish from Amazon rediscovered

Posted: 22 Apr 2013 08:11 AM PDT

Scientists have put aside nearly a century and a half of conventional wisdom with the rediscovery of a species of giant Amazonian fish whose existence was first established in a rare 1829 monograph only to be lost to science some 40 years later.

Experimental therapy saves child born 'without bones'

Posted: 22 Apr 2013 08:11 AM PDT

Four years ago, Janelly Martinez-Amador was confined to a bed, unable to move even an arm or lift her head. At age 3, the fragile toddler had the gross motor skills of a newborn and a ventilator kept her alive. She was born with thin, fragile bones, and by 3, she had no visible bones on X-rays. Initially, doctors weren't sure she would survive her first birthday. In May, Janelly will turn 7, and is developing bone with the help of an experimental drug therapy.
