But others don't. Why is this? A person who goes through experiences like that and does not get depressed has a measure of what in the psychiatric trade is known as "resilience".

Carl Bernstein (pictured right, with Bob Woodward) says journalism is the ‘best obtainable version of the truth’. Photograph: © Bettmann/CORBIS The truth is a moving target. You can see it in the fluidity of modern news – whether it comes from newspapers or Twitter – and attest to the ever-changing narratives as you try to work out what happened, when, who caused it and, crucially, what it all means. This is another way of saying that mistakes happen all day, every day. The faster you want your information, the less you cross-reference it, and the less likely it is to be true. Acknowledging mistakes is key to advancement – and not just in science | Alok Jha | Comment is free

26 September 2011Last updated at 00:22 By Richard Anderson Business reporter, BBC News Mathematicians and their trading programs are increasingly taking the place of professional investors in financial centres across the world Trading floors were once the preserve of adrenalin-fuelled dealers aggressively executing the orders of brokers who relied on research, experience and gut instinct to decide where best to invest. Long ago computers made dealers redundant, yet brokers and their ilk have remained the masters of the investment universe, free to buy and sell wherever they see fit. But the last bastion of the old order is now under threat.

Women on pill remember things differently It looked at how women on the contraceptive pill or experiencing natural hormonal cycles remembered a car accident involving a mother and son. Women using hormonal contraceptives for as little as one month remembered more clearly the main steps in the traumatic event - that there had been an accident, that the boy had been rushed to the hospital, that doctors worked to save his life and successfully reattached both his feet, for instance. Women not using them remembered more details, such as a fire hydrant next to the car. Shawn Nielsen, a graduate researcher involved in the study, said those who use contraceptives like birth control pills remember the gist of an emotional event while women not using the contraceptives better retain details.

Reindeer have to survive the light polar summer and dark polar winter Reindeer have no internal body clock, according to scientists. Researchers found that the animals are missing a "circadian clock" that influences processes including the sleep-wake cycle and metabolism. This enables them to better cope with the extreme Arctic seasons of polar day, when the sun stays up all day, and polar night, when it does not rise. The team from the universities of Manchester and Tromso report their study in Current Biology journal. Reindeer body clock switched off
10 September 2011Last updated at 02:17 By Leila Battison Science reporter Millions of years of evolution in the dark have led to this Somalian cavefish losing its eyes, scales, and pigmentation. A blind, cave-dwelling fish in Somalia knows what time it is, but its "day" is twice as long as ours. Most animals have an internal body clock, or circadian rhythm, that lasts around 24 hours and is modified by the light-dark cycle of a day. But an international team, whose research is published in the open access journal PloS Biology, shows that certain blind cave fish have a circadian rhythm that lasts almost two days. The cavefish, Phreatichthys andruzzii, has evolved for nearly two million years in the isolated darkness of caves beneath the Somali desert. Fish living in dark caves still feel the rhythm of life

9 September 2011Last updated at 15:57 Sentiment mining showed a sharp change in tone around Egypt ahead of President Mubarak's ousting Feeding a supercomputer with news stories could help predict major world events, according to US research. A study, based on millions of articles, charted deteriorating national sentiment ahead of the recent revolutions in Libya and Egypt. While the analysis was carried out retrospectively, scientists say the same processes could be used to anticipate upcoming conflict.

Internet Explorer users 'have below-average IQ' It found that Internet Explorer users scored lower than average, while Chrome, Firefox and Safari users were very slightly above average. Camino, Opera and Internet Explorer with Chrome Frame were scored "exceptionally" high. "The study showed a substantial relationship between an individual's cognitive ability and their choice of web browser," AptiQuant concluded. "From the test results, it is a clear indication that individuals on the lower side of the IQ scale tend to resist a change/upgrade of their browsers." Some people have suggested that there may be other factors at work.

18 Jul 2011: Opinion by robert engelman Demographers aren’t known for their sense of humor, but the ones who work for the United Nations recently announced that the world’s human population will hit 7 billion on Halloween this year. Since censuses and other surveys can scarcely justify such a precise calculation, it’s tempting to imagine that the UN Population Division, the data shop that pinpointed the Day of 7 Billion, is hinting that we should all be afraid, be very afraid. We have reason to be. The 21st century is not yet a dozen years old, and there are already 1 billion more people than in October 1999 — with the outlook for future energy and food supplies looking bleaker than it has for decades.
