After generics it's the turn of biosimilar drugs, a budding market

Tue, 09/09/2014 - 3:33pm
Biosimilar drugs are the complex equivalents of generic ones and are destined to make a great impact on the healthcare system over the coming years. According to a researcher, 'they are going to have an importance on a par with that of the introduction of generics.' So it is necessary to set up a suitable regulatory framework, authors of a new study say.

Miniature light-emitting devices and optical sensors: Pesky insect inspires practical technology

Tue, 09/09/2014 - 3:32pm
Our hands and swatters often fail in the struggle to kill flies. This isn't our fault, but rather is due to flies' compound eyes. Arranged in a hexagonal, convex pattern, compound eyes consist of hundreds of optical units called ommatidia, which together bestow upon flies a nearly 360-degree field of vision. With this capability in mind, a team of researchers is drawing on this structure to create miniature light-emitting devices and optical sensors.

Mapping the DNA sequence of Ashkenazi Jews

Tue, 09/09/2014 - 3:32pm
Researchers have created a data resource that will improve genomic research in the Ashkenazi Jewish population and lead to more effective personalized medicine. The team of experts focused on the Ashkenazi Jewish population because of its demographic history of genetic isolation and the resulting abundance of population-specific mutations and prevalence of rare genetic disorders.

Bacteria harbor secret weapons against antibiotics

Tue, 09/09/2014 - 3:32pm
The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide, and scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to promote rapid evolution under stress and developing antibiotic resistance in more ways than previously thought.

Liberal countries have more satisfied citizens while conservatives are happier individuals

Tue, 09/09/2014 - 3:27pm
People living in more liberal countries are happier on average than those in less liberal countries, but individually, conservatives are happier than liberals no matter where they live, according to a study of people in 16 Western European countries.

African American women receive less breast reconstruction after mastectomy

Tue, 09/09/2014 - 3:26pm
African American women are 55 percent less likely to receive breast reconstruction after mastectomy regardless of where they received their care. Breast reconstruction after mastectomy is associated with better quality of life and other benefits — in fact insurance coverage for reconstruction is legislatively mandated.

First evidence for water ice clouds found outside our solar system

Tue, 09/09/2014 - 3:07pm
A team of scientists has discovered the first evidence of water ice clouds on an object outside of our own Solar System. Water ice clouds exist on our own gas giant planets -- Jupiter, Saturn, Uranus, and Neptune -- but have not been seen outside of the planets orbiting our Sun until now.

Race, ethnicity important when evaluating risk of fat around heart

Tue, 09/09/2014 - 1:38pm
A man's likelihood of accumulating fat around his heart -- an important indicator of heart disease risk -- may be better determined if doctors consider his race and ethnicity, as well as where on his body he's building up excess fat, reveals an international evaluation.

Buckyballs and diamondoids in tiny electronic gadget: Two exotic types of carbon form molecule for steering electron flow

Tue, 09/09/2014 - 1:38pm
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

Shift in Arabia sea plankton may threaten fisheries

Tue, 09/09/2014 - 1:38pm
The rapid rise of an unusual plankton in the Arabian Sea has been documented by researchers who say that it could be disastrous for the predator fish that sustain 120 million people living on the sea's edge. "These blooms are massive, appear year after year, and could be devastating to the Arabian Sea ecosystem over the long-term," said the study's lead author.

Eating habits, body fat related to differences in brain chemistry

Tue, 09/09/2014 - 1:38pm
People who are obese may be more susceptible to environmental food cues than their lean counterparts due to differences in brain chemistry that make eating more habitual and less rewarding, according to new research.

Biologists try to dig endangered pupfish out of its hole

Tue, 09/09/2014 - 1:38pm
A biologist is giving important guidance in the efforts to rescue a critically endangered fish found only in Devils Hole, about 60 miles east of Death Valley National Park. It is estimated that fewer than 100 Devils Hole pupfish remain. Considered the world's rarest fish, the wild pupfish faces a 28 to 32 percent risk of extinction over the next 20 years.

Tracing water channels in cell surface receptors

Tue, 09/09/2014 - 1:37pm
G-protein-coupled receptors (GPCRs) mediate most of our physiological responses to external stimuli and are involved in many diseases. Scientists have now used computer modeling to uncover central steps of GPCR signal transduction. This finding could help in developing new medicines targeting this important class of cell surface receptors.
