“Science is very good at finding cause and effect,” Dr Fekete says. “You make a perfect cup or a perfect roast, but it’s a bit of luck, a matter of trial and error. By doing coffee science, we’re taking some of the guesswork and mystery out of making good coffee.”
I wonder if they have any vacancies for field testers?
I’m not sure what drew me to this experiment. That it was being conducted by someone, Taras Kul, calling himself the CrazyRussianHacker, or that it involved throwing dry ice into a swimming pool. It’s something I must try one day.
This tendency is codified in the second law of thermodynamics, which dictates that everything ages and decays: Buildings and roads crumble; ships and rails rust; mountains wash into the sea. Lifeless structures are helpless against the ravages of thermal motion. But life is different: Protein machines constantly heal and renew their cells. In this sense, life pits biology against physics in mortal combat. So why do living things die? Is aging the ultimate triumph of physics over biology? Or is aging part of biology itself?
The atmosphere of our planet could be confirmed as containing 400 parts of carbon dioxide per million within a matter of weeks, a level from which they may be no return, and something that is likely to see temperatures continue to rise.
While the 400 figure is in itself of no particular note, compared with 399 or 401, it was a marker likely to carry important symbolism. “People react to these things when they see thresholds crossed,” Dr Etheridge said. While the fraction may seem small, it is 0.04 per cent of the atmosphere. By comparison, a similar level of alcohol would be close to the legal driving limit in Australia. “These things act at low concentrations,” he said, noting that ozone-destroying chemicals at levels of parts per trillion were enough to damage that important component of the atmosphere.
The Large Hadron Collider (LHC) is due to resume operations soon, after a maintenance shutdown, and some scientists think that a batch of upcoming experiments will prove the existence of a new particle, one that might redefine their understanding of the universe. Fascinating…
Last year, researchers there recorded faint but extremely promising signs of what could be a new particle that does not fit within the current theoretical model. The LHC is now about to resume operation after being shut down since December for annual maintenance. If its next run confirms the existence of the new particle, that could open the long-sought passage to ‘the new physics’ – and, hopefully, answer some big, longstanding questions.
Hadn’t people thought this to be the case already? British physicist Stephen Hawking thinks that black holes, rather than being objects from which nothing can escape, including light, could possibly be portals to other universes. Anyone game enough to find out?
“For more than 200 years, we have believed in the science of determinism, that is that the laws of science determine the evolution of the universe” Stephen Hawking said. If information was lost in black holes, we wouldn’t be able to predict the future because the black hole could emit any collection of particles.” In an earlier talk, Hawking had said things can escape out a black hole, both from the outside and probably through another universe.
Forget about wearing the balaclava and gloves during tonight’s heist, it’s not your facial features, or finger prints, that will give you away, but rather your brainwaves, or brain prints, that stand to reveal your identity to the powers that be (though possibly a tin-foil hat might help).
Researchers at Binghamton University in US recorded the brain activity of 50 people wearing an electroencephalogram (EEG) headset while they looked at a series of 500 images designed specifically to elicit unique responses from person to person – eg a slice of pizza, a boat, or the word “conundrum.” They found that participants’ brains reacted differently to each image, enough that a computer system was able to identify each volunteer’s ‘brainprint’ with 100 per cent accuracy.
It’s a mystery how the world became awash in it. But one prevailing theory says that water originated on our planet from ice specks floating in a cosmic cloud before our sun was set ablaze, more than 4.6 billion years ago. As much as half of all the water on Earth may have come from that interstellar gas according to astrophysicists’ calculations. That means the same liquid we drink and that fills the oceans may be millions of years older than the solar system itself.
