By Nina Chestney LONDON (Reuters) - Global warming will get worse as agricultural methods accelerate the rate of soil erosion, which depletes the amount of carbon the soil is able to store, a United Nations' Environment Programme report said on Monday. [More]

Data are the currency of physics. As data accumulate, measurement uncertainty ranges narrow up to a certain point, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching consequences. In collider physics, the amount of data is measured by the total number of collisions observed, and the rate of those collisions (the luminosity).

When asked to rate their own health, women , on average, consistently report being in worse health than men do, and a new study from researchers in Spain says this is because women have a higher rate of chronic diseases -- contradicting a previous theory that women's lower self-rated health is simply a reporting bias.

The unemployment rate dropped to 8.6% last month. And that's just the beginning of the bad news. Yes, the bad news.

(PhysOrg.com) -- After some 180 days of running and four hundred trillion (4x1014) proton proton collisions, the LHC’s 2011 proton run came to an end at 5.15pm yesterday evening.

(PhysOrg.com) -- After some 180 days of running and four hundred trillion (4x1014) proton proton collisions, the LHC’s 2011 proton run came to an end at 5.15pm yesterday evening. For the second year running, the LHC team has largely surpassed its operational objectives, steadily increasing the rate at which the LHC has delivered data to the experiments.

The iPad might only be 18 months old, but she and her Android siblings are getting users to pay attention and click. Tablets are also taking the lion's share of mobile advertising dollars.

So says a new paper from the Ewing Marion Kauffman Foundation. "If we’re looking for an answer to jobs," Kauffman vice president Lesa Mitchell tells us, "it’s right in front of our face." The country is in a recession, and Washington is tangling over how to create new jobs , but, according to a new paper from the Ewing Marion Kauffman Foundation, there’s a fairly simple potential source of them sitting right under our noses.

A major government report says that the rate of excess weight and obesity among children ages two to five have doubled since the 1980s. Michelle Miller takes a look at what's being done to stop the trend.

Silicon is the dominant material for the fabrication of integrated circuits and is also becoming a popular material for making photonics circuits -- miniaturized circuits that use light instead of electronic signals for processing information.

(PhysOrg.com) -- As the Large Hadron Collider (LHC) ramps up the rate and impact of its collisions, physicists hope to witness the emergence of the Higgs boson, an anticipated, but as-yet-unseen, fundamental particle that scientists believe gives mass to matter.

(PhysOrg.com) -- Researchers at the National Institute of Standards and Technology and Wesleyan University have used computer simulations to gain basic insights into a fundamental problem in material science related to glass-forming materials, offering a precise mathematical and physical description* of the way temperature affects the rate of flow in this broad class of materials -- a long-standing goal.

Described in the March 10 issue of Nature, the NIST experiments created strong interactions between microwave light oscillating 7.5 billion times per second and a "micro drum" vibrating at radio frequencies 11 million times per second. Compared to previously reported experiments combining microscopic machines and electromagnetic radiation, the rate of energy exchange in the NIST device -- the "coupling" that reflects the strength of the connection -- is much stronger, the mechanical vibrations last longer, and the apparatus is much easier to make.

In 2010 , Americans started their own businesses at the highest rate in 15 years—but they were more apt to go at it alone, says a new study.
