Genetic switch detects TNT

A new genetic 'switch' device can detect damaging contaminants like TNT, offering a cheaper and easier method for cleaning up post-war explosive chemicals. The system is cell-free, specific, and requires minimal expertise, but further research is needed to refine its sensitivity.

Rosetta spacecraft sees sinkholes on comet

The Rosetta spacecraft has captured unprecedented imagery of comet 67P/Churyumov-Gersimenko, revealing large, circular sinkholes formed by surface collapse. The study suggests that these pits are a result of ices beneath the surface sublimating, causing the ceiling to collapse and exposing younger, relatively young ice chunks.

Helping students stick with MOOCs

Researchers developed a dropout-prediction model that uses data from one course offering to predict stopout in the next. The model achieved fairly accurate predictions and showed promise, particularly when incorporating additional variables like weekend study habits. Ongoing work aims to refine the model for improved accuracy.

Evaluation of NK1 antagonists for emesis prevention in oxaliplatin chemo: SENRI trial

The SENRI trial found that NK1 antagonists significantly increased the inhibition rate of vomiting and nausea, especially in females. The three-drug combination therapy of aprepitant, a 5-HT3 receptor antagonist, and dexamethasone may be a good antiemetic treatment option for oxaliplatin-based chemotherapy in patients with colorectal c...
