No peak in sight for evolving bacteria

Posted: 14 Nov 2013 11:22 AM PST

There's no peak in sight -- fitness peak, that is -- for the bacteria being studied in one American lab. Scientists there have been running an evolutionary bacteria experiment for 25 years, generating more than 50,000 generations. In a paper published, the author compares it to hiking.

Distant artificial atoms cooperate by sharing light: Future applications in advanced quantum devices

Posted: 14 Nov 2013 11:21 AM PST

Scientists have shown for the first time that atoms can work collectively rather than independently of each other to share light. Quantum physicists have long discussed such an effect, but it has not been seen before in an experiment.

Quantum world record smashed: Quantum state survives at room temperature for 39 minutes

Posted: 14 Nov 2013 11:21 AM PST

A normally fragile quantum state has been shown to survive at room temperature for a world record 39 minutes, overcoming a key barrier towards building ultrafast quantum computers.

Hydrogen fuel from sunlight? Low-cost, long-lasting water splitter made of silicon and nickel

Posted: 14 Nov 2013 11:21 AM PST

Scientists have created a silicon-based water splitter that is both low-cost and corrosion-free. The novel device -- a silicon semiconductor coated in an ultrathin layer of nickel -- could help pave the way for large-scale production of clean hydrogen fuel from sunlight.

Toward new quantum possibilities: Seeing a photon without absorbing it

Posted: 14 Nov 2013 11:19 AM PST

Scientists can detect an optical photon twice. Light is of fundamental importance. It allows us to see the world around us and record pictures of our environment. It enables communication over long distances through optical fibers. All current methods of detecting light share a common property: absorption and thus destruction of a photon. It has been a long-standing dream to be able to watch individual photons fly by without absorbing them. Scientists have now for the first time realized a device which leaves the photon untouched upon detection. This provides new possibilities for using single photons in quantum communication and quantum information processing.

Penguin-inspired propulsion system

Scientists who have explored leveraging penguins' "rocket" properties to create new propulsion technologies with high maneuverability and improved hydrodynamic efficiency, are creating a penguin-inspired propulsion system that uses a novel spherical joint mechanism.

Jupiter mystery solved: Why the giant planet's mysterious Great Red Spot has not disappeared

Posted: 14 Nov 2013 10:19 AM PST

Based on what scientists understand about fluid dynamics, Jupiter's Great Red Spot should have disappeared centuries ago. Astronomers now think they can explain why. Their work also provides insight into persistent ocean eddies and vortices that contribute to star and planet formation.

Hubble reveals first scrapbook pictures of Milky Way's formative years

Posted: 14 Nov 2013 08:36 AM PST

NASA's Hubble Space Telescope has provided the first visual evidence showing how our home galaxy, the Milky Way, assembled itself into the majestic pinwheel of stars we see today. Perusing Hubble's deep-sky surveys, astronomers traced 400 galaxies similar to our Milky Way at various stages of construction over a time span of 11 billion years.

Mind-reading robots coming ever closer

Posted: 14 Nov 2013 07:25 AM PST

If you think with the release of every new i-device the world is getting closer to thought-controlled smart tech and robotic personal assistants, you might be right.

Accidental discovery dramatically improves electrical conductivity

Posted: 14 Nov 2013 06:49 AM PST

Quite by accident, researchers have achieved a 400-fold increase in the electrical conductivity of a crystal simply by exposing it to light. The effect, which lasted for days after the light was turned off, could dramatically improve the performance of devices like computer chips.

Could next new cancer drug come from Kentucky coal mines?

Posted: 13 Nov 2013 09:56 AM PST

In their ongoing quest to develop the latest and most effective drugs for disease treatment, researchers are looking deep — as in, deep underground.
