Discovery provides insights on how plants respond to elevated CO2 levels
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
Building a better battery
A new battery technology provides double the energy storage at lower cost than the batteries that are used in handheld electronics, electric vehicles, aerospace and defence.
Inexpensive material boosts battery capacity
Battery-powered cars offer many environmental benefits, but a car with a full tank of gasoline can travel further. By improving the energy capacity of lithium-ion batteries, a new electrode made from iron ...
How plants sense touch, gravity and other physical forces
(PhysOrg.com) -- At the bottom of plants' ability to sense touch, gravity or a nearby trellis are mechanosensitive channels, pores through the cells' plasma membrane that are opened and closed by the deformation ...
Discovery of extremely long-lived proteins may provide insight into cell aging
One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain ...
Tiny reader makes fast, cheap DNA sequencing feasible
Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.
Aiming to boost electronics performance, researchers capture images of sub-nano pore structures for the first time
(PhysOrg.com) -- Moore's law marches on: In the quest for faster and cheaper computers, scientists have imaged pore structures in insulation material at sub-nanometer scale for the first time. Understanding ...
Team uses forest waste to develop cheaper, greener supercapacitors
Researchers report that wood-biochar supercapacitors can produce as much power as today's activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts.
U.S. team creates diamond aerogel in lab by emulating Mother Nature
Glass that cleans itself
Eyeglasses need never again to be cleaned, and dirty windscreens are a thing of the past! Researchers at the Max Planck Institute for Polymer Research in Mainz and the Technical University Darmstadt are now ...
Shocking new way to create nanoporous materials revealed
Scientists have developed a new method of creating nanoporous materials with potential applications in everything from water purification to chemical sensors.
Climate change: More carbon dioxide leads to fewer clouds
(Phys.org)—The warmer the air, the more water can evaporate: a simple relationship familiar to us from everyday life. Researchers from Germany and the Netherlands have now established that this is not always ...
Ancient fossilized sea creatures yield oldest biomolecules isolated directly from a fossil
(Phys.org)—Though scientists have long believed that complex organic molecules couldn't survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and ...
New technique produces highly selective filter materials
Researchers have devised a way of making tiny holes of controllable size in sheets of graphene, a development that could lead to ultrathin filters for improved desalination or water purification.
