CDC director admits safety problems at germ labs

July 16, 2014 4:22 pm | by Mike Stobbe - AP Medical Writer - Associated Press | News | Comments

The director of the Centers for Disease Control and Prevention acknowledged Wednesday that systemic safety problems have for years plagued federal public health laboratories that handle dangerous germs such as anthrax and bird flu. Testifying at a congressional hearing in Washington, CDC Director Dr. Tom Frieden said the agency had long thought of the lapses as unrelated accidents.

Study: Squid skin protein could improve biomedical technologies

July 16, 2014 2:24 pm | News | Comments

The common pencil squid may hold the key to a new generation of medical technologies that could communicate more directly with the human body. Materials science researchers in California have discovered that reflectin, a protein in the tentacled creature’s skin, can conduct positive electrical charges, or protons, making it a promising material for building biologically inspired devices.

Trying gene therapy to create biological pacemaker

July 16, 2014 2:22 pm | by Lauran Neergaard - AP Medical Writer - Associated Press | News | Comments

No batteries required: Scientists are creating a biological pacemaker by injecting a gene into the hearts of sick pigs that changed ordinary cardiac cells into a special kind that induces a steady heartbeat. The study, published Wednesday, is one step toward developing an alternative to electronic pacemakers that are implanted into 300,000 Americans a year.

Dispersant from Deepwater Horizon spill found to persist in the environment

July 16, 2014 12:51 pm | News | Comments

In an attempt to prevent vast quantities of oil from fouling beaches and marshes after the 2010 Deepwater Horizon spill in the Gulf of Mexico, BP applied 1.84 million gallons of chemical dispersant. The dispersant was thought to rapidly degrade in the environment, but a new study has found that the DOSS dispersant compound remains associated with oil and can persist in the environment for up to four years.

Bubble wrap serves as sheet of tiny test tubes in resource-limited regions

July 16, 2014 11:46 am | News | Comments

Popping the blisters on the bubble wrap might be the most enjoyable thing about moving. But now, researchers led by 2007 R&D Magazine Scientist of the Year George Whitesides propose a more productive way to reuse the popular packing material: as a sheet of small, test tube-like containers for medical and environmental samples. Analyses can take place right in the bubbles.

Breakthrough in the development of stretchable optical waveguides

July 16, 2014 10:33 am | News | Comments

Scientists in Belgium have recently fabricated the world’s first randomly deformable optical waveguide. This innovative optical link remains functional for bending radii down to 7 mm, and can be stretched to more than a third of its length. A link like this can be used to interconnect optical components within a stretchable system, just like stretchable electrical interconnections.

Ultra-high Performance Liquid Chromatograph

July 16, 2014 10:10 am | Product Releases | Comments

Thermo Fisher Scientific has unveiled a new high performance liquid chromatography system, the Vanquish UHPLC. The monolithic case contains an instrument that combines the ruggedness of an integrated system with the flexibility and serviceability of a modular system. Vanquish stands about 25% lower than comparable modular stacks for safety and convenience in the laboratory.

Researchers develop simple procedure to obtain nanosized graphene

July 16, 2014 9:34 am | Videos | Comments

A team including scientists from Spain and from IBM Research in Switzerland have published work which describes an extremely simple method to obtain high quality nanographenes from easily available organic compounds. This method is based on the reactivity of a group of molecules named arynes, which can act as "molecular glue" to paste graphene fragments together.

Self-assembling nanoparticle could improve MRI cancer scanning

July 16, 2014 8:44 am | News | Comments

Scientists have designed a new self-assembling nanoparticle that targets tumors, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers in the U.K., boosts the effectiveness of magnetic resonance imaging scanning by specifically seeking out receptors that are found in cancerous cells.

NASA’s Van Allen probes show how to accelerate electrons

July 16, 2014 7:50 am | News | Comments

One of the great, unanswered questions for space weather scientists is just what creates two gigantic donuts of radiation surrounding Earth, called the Van Allen radiation belts. Theories abound, but probes sent by NASA have recently provided the first really strong confirmation of what's happening. For the first time, scientists can explain how the electrons are accelerated up to nearly the speed of light.

Powerful new sensor amplifies optical signature of single molecules by 100 billion times

July 15, 2014 5:19 pm | News | Comments

Scientists in Texas have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. The new imaging method uses a form of Raman spectroscopy in combination with an intricate but mass reproducible optical amplifier. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 atoms.
