Seventy-five per cent of the world's heather moorlands are in the UK. However, pollution, overgrazing and wild fires have damaged large areas. Several organisations in the Peak District National Park are trying to restore and conserve the moorland habitat.

Innovative sound-mapping software based on human hearing has been developed to help architects design out unwanted noise.
The new software generates audibility maps of proposed room designs.
The EPSRC (Engineering and Physical Sciences Research Council) project has been developed at Cardiff University.
These maps show hotspots where conversations would not be intelligible if the room were busy. Architects can then adjust their designs to reduce reverberation until the hotspots are eliminated and audibility is maximised.
Washington, DC, USA – Today, during the 39th Annual Meeting of the American Association for Dental Research, convening at the Walter E. Washington Convention Center in Washington, DC, lead researcher M. Tong, The Ohio State University, will present a poster of a study titled "Epithelial-to-Endothelial Transition: An Epithelial Phenotypic Modulation Facilitating Oral-Squamous-Cell Carcinoma Progression." Tong and a team of researchers have reported that oral squamous cell carcinoma (OSCC) cells endogenously produce exceptionally high levels of vascular endothelial growth factor (VEGF).
UPTON, NY — An international team of scientists studying high-energy collisions of gold ions at the Relativistic Heavy Ion Collider (RHIC), a 2.4-mile-circumference particle accelerator located at Brookhaven National Laboratory, has published evidence of the most massive antinucleus discovered to date. The new antinucleus, discovered at RHIC's STAR detector, is a negatively charged state of antimatter containing an antiproton, an antineutron, and an anti-Lambda particle. It is also the first antinucleus containing an anti-strange quark.
Keeping an infrared telescope at very cold operating temperatures isn't an option, it's an absolute necessity. For the James Webb Space Telescope to see the traces of infrared light generated by stars and galaxies billions of light years away, it must be kept at cryogenic temperatures of under 50 Kelvin (-370°F). Otherwise, sunlight would warm the telescope and this heat from the telescope itself will swamp the very faint astronomical signals, effectively blinding the telescope's eye. The job of the huge, five-layer sunshield is to keep that from happening.
By accurately re-creating the jumbled wireless signal environment of a city business district in a special indoor test facility, researchers at the National Institute of Standards and Technology (NIST) have shown how the wireless industry could lop hours off the process of testing the capabilities of new cellular phones. The NIST techniques also could simulate complex real-world environments for design and test of other wireless equipment.
Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20 percent efficiencies, the cost of this solar power is prohibitive for large-scale use. Researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab), however, are developing a new approach that could substantially reduce these costs. The key to their success is a better way of trapping sunlight.
If harnessing the unlimited solar power of the sun were easy, we wouldn't still have the greenhouse gas problem that results from the use of fossil fuel. And while solar energy systems work moderately well in hot desert climates, they are still inefficient and contribute only a small percentage of the general energy demand. A new solution may be coming from an unexpected source ― a source that may be on your dinner plate tonight.
Blacksburg, Va. -- Students at Virginia Tech's Unmanned Systems Laboratory are perfecting an autonomous helicopter they hope will never be used for its intended purpose. Roughly six feet long and weighing 200 pounds, the re-engineered aircraft is designed to fly into American cities blasted by a nuclear weapon or dirty bomb.
The helicopter's main mission would be to assist military investigators in the unthinkable: Enter an American city after a nuclear attack in order to detect radiation levels, map and photograph damage.
HOUSTON - In a new study from The University of Texas M. D. Anderson Cancer Center, researchers found that cystoscopy, the standard for screening for recurrence of early-stage bladder cancer, is a cost-effective method of detecting tumors.
Adding other tests to cystoscopy increases the cost, as well as the number of false positives that may result in emotional distress and unnecessary procedures, the investigators include.
ANN ARBOR, Mich.---The most common digital security technique used to protect both media copyright and Internet communications has a major weakness, University of Michigan computer scientists have discovered.
RSA authentication is a popular encryption method used in media players, laptop computers, smartphones, servers and other devices. Retailers and banks also depend on it to ensure the safety of their customers' information online.
Mini- thrusters or miniature, electric propulsion systems are being developed, which could make it easier for the Air Force's small satellites, including the latest CubeSats, to perform space maneuvers and undertake formidable tasks like searching for planets beyond our solar system.
WEST LAFAYETTE, Ind. — Purdue University researchers have developed a miniature device capable of converting ultrafast laser pulses into bursts of radio-frequency signals, a step toward making wires obsolete for communications in the homes and offices of the future.
Such an advance could enable all communications, from high-definition television broadcasts to secure computer connections, to be transmitted from a single base station, said Minghao Qi, an assistant professor of electrical and computer engineering.
LAWRENCE, Kan. — People who lie on online dating services likely are people-pleasers who want to present themselves in the most favorable light to get someone to like them — just as they would in face-to-face dating, according to a University of Kansas researcher.
Scientists at L'Oréal, in hot pursuit of the hidden elements of beauty, seem well on their way to disputing the old adage, "beauty is only skin deep." In fact, their work indicates that what makes hair curly or straight and skin smooth or rough, is much deeper. It actually is linked to molecules within the body, according to an article in Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.
