Neil deGrasse Tyson shared “deeply cosmic” thoughts, whatever that is supposed to mean, and then “a fascinatingly disturbing thought” - watch it on liveleak.
There is a lot one can criticize* about his claims, however, he is missing something obvious that stands out like a sore thumb: Silicon!
Billions of stars in our galaxy have acquired released planets that once roamed interstellar space. Those free agent worlds left the star systems in which they formed, and found a new home with a different sun.
If it sounds a lot like baseball, that's because it is, said Hagai Perets of the Harvard-Smithsonian Center for Astrophysics, making the most incongruent cosmological metaphor of April 17th, 2012.
A small marine worm, Olavius algarvensis, is faced with a scarce food supply in the sandy sediments it lives in off the coast of Elba, so it must deal with a highly poisonous menu: it lives on carbon monoxide and hydrogen sulfide.
O. algarvensis can thrive on these poisons thanks to millions of symbiotic bacteria that live under its skin. The bacteria use the energy from carbon monoxide and hydrogen sulphide to produce food for the worm, just like plants do by fixing carbon dioxide into carbohydrates - but instead of using light energy from the sun, the symbionts use the energy from chemical compounds like carbon monoxide.
Dye-sensitized solar cells (DSC) are easier to manufacture than silicon-based solid-state photovoltaic cells but not as efficient. Some new research may make carbon nanotubes a more efficient alternative for platinum electrodes in dye-sensitized solar cells, making them more viable overall.
Wikipedia is crowdsourced knowledge and therefore discourages people from writing about themselves. As a result, 60 percent of Wikipedia articles about companies contain factual errors, according to research published in Public Relations Journal.
Marcia W. DiStaso, Ph.D., assistant professor of public relations at Penn State University, surveyed 1,284 public relations people from the Public Relations Society of America's (PRSA). Results of the survey indicate a gap exists between public relations companies and Wikipedia concerning the proper protocol for editing entries.
Whether you are concerned about Mayans, a worldwide infrastructure collapse or an exploding supervolcano, science has some good news for your doomsday preparation - sunlight and a twist of lime are an inexpensive and effective way to quickly improve the quality of your drinking water.
Researchers have found that adding lime juice to water while using a solar disinfection method removed detectable levels of harmful bacteria such as Escherichia coli (E. coli) significantly faster than solar disinfection alone.
It was back in 2005 that inventor
Boris Volfson was granted a US patent for a device which has been erroneously summarised by some as a 'Flying Saucer'. But which is more accurately described as a
Space Vehicle Propelled by the Pressure of Inflationary Vacuum State. Although the patent explained at length how “A levitating, rotating, superconducting disk“ might be able to develop a temporary egg-shaped space-time anomaly sufficient to allow a passenger vehicle to travel faster than light, the exact physics behind the crucial component known as the ‘Phonon Maser’ may have remained opaque to many readers.
It's called
Knowledge and it's a short story by John Frizell in
Nature. Did you know that
Nature publishes short stories, one at the back of every issue? They do!
No human could have grasped the squid's name. Human eyes could not distinguish the differences in shades of colour or register the intervals at which they changed to define the unique pattern that was his name. The squid was concentrating hard because he was holding two conversations at once, one deliberately misleading, the other closer to the truth, as he glided through the deep ocean, his mantle pulsing gently, powering him with puffs of water.
Proteins are large, organic - in the science sense of organic, not the food marketing sense - molecules that help us to convert food into energy, supply oxygen to our blood and muscles and drive our immune systems.
Proteins consist of one or more polypeptides, chains of amino acids held together by peptide bonds. If a protein in water is heated to temperatures approaching the boiling point of water, these chains will lose their structure and the protein will denature (unfold).
Evolution has various mechanisms and one of them is natural selection. While most religious people have no disagreement with science overall, Biblical literalists contend man cannot have changed or evolved. Some confusion about evolution is understandable - evolution is darn complex - and the disagreement with evolution does not fall strongly into any demographic except the religious. In America, we hear more about 'the religious right' but primarily we hear about them from the secular left - while noting that 39% of Republicans don't accept evolution they fail to mention 30% of Democrats don't either.
