By Nina Chestney LONDON (Reuters) - The world is close to reaching tipping points that will make it irreversibly hotter, making this decade critical in efforts to contain global warming, scientists warned on Monday. Scientific estimates differ but the world's temperature looks set to rise by six degrees Celsius by 2100 if greenhouse gas emissions are allowed to rise uncontrollably. As emissions grow, scientists say the world is close to reaching thresholds beyond which the effects on the global climate will be irreversible, such as the melting of polar ice sheets and loss of rainforests

Filing patent applications between now and March 2013, while the first-to-invent rules are still in place, can provide some significant benefits. Companies should proactively manage their intellectual property strategy to make the most of this opportunity.

Humankind’s efforts to tell time have helped drive the evolution of our technology and science throughout history. The need to gauge the divisions of the day and night led the ancient Egyptians, Greeks and Romans to create sundials, water clocks and other early chronometric tools. Western Europeans adopted these tech

On top of the critical shortage of potentially life saving drugs in America, terminally ill patients are up against drug companies dealing on the gray market and exploiting the short supply. Armen Keteyian reports.

(PhysOrg.com) -- Experiments at the Department of Energy’s Fermilab are close to reaching the critical sensitivity that is necessary to look for the existence of a light Higgs particle. Scientists from both the CDF and DZero collider experiments at Fermilab will present their new Higgs search results at the EPS High-Energy Physics conference, held in Grenoble, France, from July 21-27.

LINDAU, Germany--There's a magazine ad for an expensive skin care product marketed by Christian Dior that claims to trade on aquaporins, the discovery of which by Peter Agre won him the Nobel Prize in chemistry in 2003 (he shared it with Roderick MacKinnon).

(PhysOrg.com) -- Like an opera singer hitting a note that shatters a glass, a signal at a particular resonant frequency can concentrate energy in a material and change its properties. And as with 18th century "musical glasses," adding a little water can change the critical pitch. Echoing both phenomena, researchers at the National Institute of Standards and Technology (NIST) have demonstrated a unique fluid-tuned "metasurface," a concept that may be useful in biomedical sensors and microwave-assisted chemistry.

You're not going to like hearing this: the arsenal of mental and physical resources is out there right now could easily bring down our cybersecurity system, which protects the trivial, such as emails, to the critical, think banking system. The only reason it hasn't happened yet: the intent hasn't been there. [More]

NEW YORK (Reuters Health) - Many daily skin creams that claim to provide ultraviolet protection and anti-aging benefits may not have enough of the critical ingredients needed to block UV-A light, according to new research.
