Artificial Photosynthesis: Turning Sunlight Into Liquid Fuels Moves A Step Closer
Through photosynthesis, plants use sunlight to convert water and carbon dioxide into sugars they use for fuel. Scientists want to create an artificial version of photosynthesis to produce liquid fuels...
Caravaggio was early 'photographer'
Caravaggio used an early form of photography to create his masterpieces - 200 years before the invention of the camera, a researcher claims.
Opinion: Concentrating solar powered desalination - a solution to our water problems?
Australia needs electricity and Australia needs water. Concentrating solar power could provide both, writes Stewart Taggart.
Aussies set X-ray standards
Australian scientists have developed the first international standards that border-protecting X-ray equipment around the world will have to meet.
Applied research is ousting curiosity-driven science
When funders focus on market-driven and applied science they hinder basic scientific enquiry in developing countries, says Lemuel V. Cacho.
Cosmic Log: Tales of the big bang
Science editor Alan Boyle's Weblog: A researcher who is working on the world’s biggest physics experiment — and the second-biggest experiment — explores the quantum frontier in a new book.
New Genre Of Sugar-coated 'Quantum Dots' For Drug Delivery
Scientists in Switzerland are reporting an advance that could help tap the much-heralded potential of "quantum dots"-- nanocrystals that glow when exposed to ultraviolet light -- in the treatment of...
Mechanism To Increase Magnetic Response Of Ferromagnetic Semiconductor Identified
When squeezed, electrons increase their ability to move around. In compounds such as semiconductors and electrical insulators, such squeezing can dramatically change the electrical- and magnetic- properties. Now scientists have...
Breath or urine analysis may detect cancer, diabetes
A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing...
Cherry A. Murray is named dean of SEAS
Cherry A. Murray, who has led some of the nation’s most brilliant scientists and engineers as an executive at Bell Laboratories and the Lawrence Livermore National Laboratory, has been appointed...
Terrorism Fears Top Public Information
Chemical company pressure drives Chemical Safety Board to cancel public meeting on fatal accident
Study Rules Out Fröhlich Condensates in Quantum Consciousness Model
(PhysOrg.com) -- Scientists don't fully understand how consciousness works, and, so far, no classical theories can explain consciousness in the brain. In light of this lack of understanding, some researchers...
Ultra-thin Chip Embedding For Wearable Electronics
Technologists have created a new 3D integration process enabling flexible electronic systems with a thickness of less than 60 micrometer. This ultra-thin chip package (UTCP) technology allows integrating complete systems...
Double graphene coat is slippery stuff
Two layers of carbon atoms could reduce wear and tear in tiny machines
Models Present New View Of Nanoscale Friction
Friction is a force that affects any application where moving parts come into contact; the more surface contact there is, the stronger the force. At the nanoscale -- mere billionths...
World's largest laser gears up for ignition experiments
(PhysOrg.com) -- Construction of the National Ignition Facility (NIF), the world's largest and highest-energy laser system, was essentially completed on Feb. 26, when technicians at Lawrence Livermore National Laboratory (LLNL),...
Samsung Launches 1.5 Terabyte 'EcoGreen' F2EG Hard Disk Drive
Samsung Electronics today announced its new EcoGreen F2EG hard disk that delivers a massive 1.5TB of capacity with 500GB per disk. With increased recording density and reduced number of disks,...
Observatory: With Fibers, Chemical Reactions on a Tiny Scale
Tiny chemical reactors made of thin fibers may allow researchers to study how chemical reactions occur on a really small scale.
New gel offers controlled drug delivery
MIT researchers have demonstrated that a gel composed of small, woven protein fragments can successfully carry and release proteins of different sizes, potentially enabling delivery of drugs such as insulin...
A water splitter with a double role
(PhysOrg.com) -- There is a lot of hope invested in hydrogen, but it also presents some problems. It is energy-rich, clean and, as a constituent of water, of almost unlimited...
The Next Step in Revolutionary Electronics
Accidental discovery of the elusive "memristor" electronic component. It could soon replace both RAM and hard drives with devices 10x smaller. Cell phones might become sensors, protecting planet Earth. Credit:...
Startup gives boost to electric cars: 'vending machines for electricity'
Richard Lowenthal used to worry about the electric-auto industry's chicken-and-egg question: Which will come first, the chargers or the cars?
