Tragedies at NASA, such as Challenger and Columbia disasters, have impeded the organization from taking risks, critics say. Indeed, in terms of PR, these tragedies were particularly baleful. Although NASA was once a contractor, its staff spearheading missions, today they are more a client. SpaceX is basically selling NASA a ride to the ISS. Essentially, NASA has put the risk on private companies

The herds appear to aimlessly move back and forth through meadows threaded by a winding river, just passive figures in an idyllic scene. But, as it turns out, that's far from the full picture.
Indiana University researchers have identified a mechanism involving the body's ability to resist fungal infection. The work could help advance research on cancer therapies that use the body's own immune system to fight disease.
There's a long-standing belief in the freshwater fishing community that once anglers find it too hard to land a particular fish for their dinner plate, they either move on to fishing for different species or fish in new waters, giving depleted populations time to rebound.
The oldest living organism on Earth is a plant, Methuselah a bristlecone pine (Pinus longaeva) that is over 5000 years old. Conversely, animals only live up to a few hundred years. Can we learn something from plants about longevity and stay young forever or even recapture lost youth?

Walking on Caltech's campus, research engineer Chris Roh (MS '13, Ph.D. '17) happened to see a bee stuck in the water of Millikan Pond. Although it was a common-enough sight, it led Roh and his advisor, Mory Gharib (Ph.D. '83), to a discovery about the potentially unique way that bees navigate the interface between water and air.
Using a powerful supercomputer, scientists have created a state-of-the-art simulation of galactic formation. While previous simulations typically had to choose between showing a big-picture view or being highly detailed, the TNG50 simulation is both. Not only does it show how a whole universe may have formed in the 13.8 years since the Big Bang , but it also gives scientists the ability to zoom i

The experience of stress and fear upon hospitalization is frequent with pediatric patients . The findings suggest that a magic therapy program for pediatric inpatient care may have great value to patients and caregivers while they're in the hosp
It's a long way to Mars. At its closest, it's still 55 million kilometers away from the Earth, meaning that depending on how fast you're traveling, it'd still take at least five months . But there might be a way to make the journey less taxing: hibernation, an idea that has so far been limited to the realm of science fiction. A special dedicated panel made up of European Space Agency (ESA) scient
What's the best way to get people to change their behavior? In this funny, information-packed talk, psychologist Dan Ariely explores why we make bad decisions even when we know we shouldn't — and discusses a couple tricks that could get us to do the right thing (even if it's for the wrong reason).
A few years ago, Jason Rentfrow, a psychologist at the University of Cambridge, dug into a question that has captivated him for decades: Do different places have different personalities? Do people in Los Angeles, for instance, have measurably different temperaments than the residents of Augusta, Georgia? If so, what does that mean for both places? Rentfrow decided to test these questions on a phe
According to the chaos theory in mathematics, a minute change such as the 'flap of a butterfly's wing' could cause huge changes elsewhere. This seems to hold true at much smaller scales too–for example, within a cell. Scientists from the National Centre for Biological Sciences (NCBS), Bangalore, have now found how a minuscule atomic change in a protein molecule enables the bacterium to shut down
New research published this month in the Southern Economic Journal reveals job losses during the Great Recession (2007-2009) may be partly responsible for the recent drop in U.S. birth rates.
Teenagers with the contamination and washing variant of OCD are not generally more ill than children and adolescents with other forms of disabling obsessive thoughts and compulsive behaviour.
