Engineers have developed and successfully demonstrated the value of a simple pulley mechanism to improve hand function after surgery. The device, tested in cadaver hands, is one of the first instruments ever created that could improve the transmission of mechanical forces and movement while implanted inside the body.

After continued research, technology such as this may offer new options to people who have lost the use of their hands due to nerve trauma, and ultimately be expanded to improve function of a wide range of damaged joints in the human body.

Neurons programmed to fire at specific faces, such as the famously reported "Jennifer Aniston neuron", may be more in line with the conscious recognition of faces than the actual images seen.

In an experiment, subjects presented with a blended face, such as an amalgamation of Bill Clinton and George W. Bush, had significantly more firing of such face-specific neurons when they recognized the blended or morphed face as one person or the other. 

A bright orange poison dart frog with a unique call was discovered in Donoso, Panama, and described by researchers from the Smithsonian Tropical Research Institute and the Universidad Autónoma de Chiriquí in Panama, and the Universidad de los Andes in Colombia.

Andinobates geminisae is named for Geminis Vargas, "the beloved wife of [coauthor] Marcos Ponce, for her unconditional support of his studies of Panamanian herpetology." 

Astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space -  27,000 light years away. Like finding a molecular needle in a cosmic haystack, astronomers have detected radio waves emitted by isopropyl cyanide. The discovery suggests that the complex molecules needed for life may have their origins in interstellar space.

Using the Atacama Large Millimeter/submillimeter Array (ALMA), researchers studied the gaseous star-forming region Sagittarius B2.

A review in the Journal of Animal Science has found that feeding livestock diets containing genetically engineered crops has no impact on the health or productivity of those animals.

The article documents 30 years worth of livestock-feeding studies, representing more than 100 billion animals, finding that the performance and health of food-producing animals fed GE crops are comparable with those of animals fed non-GE crops. 

Since their introduction in 1996, GE feed crops have become an increasing component of livestock diets. Today, more than 95 percent of U.S. food-producing animals consume feed containing GE crops. Studies that involve feeding GE crops to livestock are used to evaluate the safety of these crops. 

Rolapitant reduces nausea and vomiting in patients receiving cisplatin-based chemotherapy, according to the results of a phase III trial presented for the first time today at the ESMO 2014 Congress in Madrid, Spain.

Afatinib, a tyrosine kinase inhibitor, significantly improved progression-free survival compared to methotrexate in patients with recurrent or metastatic squamous cell carcinoma of the head and neck after failure of platinum-based chemotherapy, the results of a phase III trial presented at the ESMO 2014 Congress in Madrid show.

The Lux-Head&Neck 1 trial showed that patients who received treatment with 40 mg/day oral afatinib had a 20% reduction in risk of progression or death compared to patients who received methotrexate, with a median progression-free survival of 2.6 months.

Medinah Country Club, Chicago, Ryder Cup 2012. There were six short feet between Martin Kaymer and the 18th hole. This was the moment. No other player, no spectator, none of the many millions watching on television would have dared breathe. The seconds stretched as the German composed himself for his final shot.

The public is not aware of this, but academic science is more like a small business than being part of a vast university structure. An investigator is the business owner and the researchers are independent contractors, augmented by graduate students who go to the school.

In that sort of environment, where the life and death of the business is determined by beating other labs for a finite pool of money, while the government spends billions to try and increase the number of competitors who want to be in government-funded academia rather than the private sector, competitive instincts run high.

Sharing data either dilutes the strength of a research group or it allows a competitor to have a shortcut that another lab funded.  Lose-lose. 

NASA's Aqua satellite captured strong thunderstorms with colder cloud tops that have grown within Tropical Storm Rachel in the Eastern Pacific Ocean.

Aqua passed over the large Tropical Storm Rachel on Sept. 25 at 4:41 p.m. EDT and the Atmospheric Infrared Sounder or AIRS instrument, saw that the extent of colder cloud tops had increased, indicating thunderstorm heights were increasing and it was strengthening. The expansion of those stronger thunderstorms also suggests that the northeasterly wind shear may be relaxing a little. The strongest thunderstorms remain limited to the southwest of the low-level center,
