A naturally decaffeinated coffee plant has been discovered. Coffee from the new strain could be tastier than existing decaf brews, which can lose flavour compounds when caffeine is extracted with solvents.
Other caffeine-free plants have been reported, but the latest comes from the same genetic stock as today’s elite commercial strains. This means the decaffeinated trait should be relatively easy to breed into popular types of coffee.
Scientists have performed successful teleportation on atoms for the first time, the journal Nature reports.
The feat was achieved by two teams of researchers working independently on the problem in the US and Austria.
The ability to transfer key properties of one particle to another without using any physical link has until now only been achieved with laser light.
Experts say being able to do the same with massive particles like atoms could lead to new superfast computers.
In a step toward making ultra-powerful computers, scientists have transferred physical characteristics between atoms by using a phenomenon so bizarre that even Albert Einstein called it spooky.
Such "quantum teleportation" of characteristics had been demonstrated before between beams of light.
The work with atoms is "a landmark advance," H.J. Kimble of the California Institute of Technology in Pasadena, California, and S.J. van Enk of Bell Labs in Murray Hill, New Jersey, declare in Thursday's issue of the journal Nature.
A French mathematician is claiming to have solved a fiendishly difficult problem, upon which rides a million dollars of prize money. But other mathematicians are sceptical that he has really done it.
On Tuesday, Louis de Branges de Bourcia, a professor of mathematics at Purdue University in Indiana, issued a press release claiming that he has proved the Riemann hypothesis is true.
"Toxic dust" found on computer processors and monitors contains chemicals linked to reproductive and neurological disorders, according to a new study by several environmental groups.
The survey, released Thursday by Silicon Valley Toxics Coalition, Computer TakeBack Campaign and Clean Production Action, is among the first to identify brominated flame retardants on the surfaces of common devices in homes and offices.
