Athletes sometimes 'choke' - succumb to pressure and underperform - in key situations. How can an athlete be among the top 1,000 participants in the world at a task and be paralyzed by situations in a game they play with expertise?

Choking happens to lots of people.  We've all heard people say they can't take tests, for example.  A new analysis from the California Institute of Technology (Caltech) suggests that when there are higher incentives to succeed, people can become so afraid of losing their potential reward that their performance suffers.

It's no surprise that tattoos and piercings have been linked to other risky decisions but capped Internet bandwidth?  

People who claim to see the 'aura' of others - and subsequently claim they can modify them - may actually have synesthesia, according to new research.

Synesthesia is believed to occur due to cross-wiring in the brain; synesthetes have more synaptic connections than 'normal' people and some are interconnected in ways others are not, including across brain regions. Since the brain regions responsible for the processing of each type of sensory stimuli are intensely interconnected, synesthetes see or taste a sound, feel a taste, or associate people with a particular color.

Shortly after celebrating the tenth anniversary of its time in service, engineers have declared the Envisat satellite lost, following numerous attempts to re-establish contact since April 8th.

Which countries are the best at providing higher education?

 The Universitas 21 Ranking was announced today at Lund University in Sweden. Universitas 21, a network of research universities, has developed their own ranking as a benchmark for governments, education institutions and individuals to highlight the importance of creating a strong environment for higher education institutions that will contribute to economic and cultural development, provide a high-quality experience for students and help institutions compete for overseas applicants. 

So calibrate accordingly when the metrics for 'higher education' don't actually mention education.

How can basically honest scientists using a rigorous methodology have different data?  Numerical models are tricky business and while climate scientists are rapidly becoming experts in statistics and creating better models, that was not always the case.

One vital component of getting clean models is accurate calibration. Calibration is life, in science.  A satellite temperature record put together by the University of Alabama in Huntsville in 1989 has often been cited by climate change skeptics as evidence of doubt that models showing the impact of greenhouse gases on global warming are accurate.
