While various cyber-attacks against US government and business targets are numerous and well-documented, America's own offensive capabilities in this area have remained mostly out of view. However, in his recent testimony before Congress, NSA chief Lt. General Keith Alexander reversed that history a bit, and confirmed that the US has, and is, engaged in offensive cyber-warfare. Alexander also explicated how cyber-combat factors into the general doctrine of legality of war.
After months of deliberation and 150 meetings, the Obama Administration finally released its new guidelines for nuclear weapons policy. In a sharp break from previous administrations, Obama's Nuclear Posture Review released today dictates the U.S. halt development of any new nuclear weapons and cease to consider nuclear retaliation against non-nuclear nations, even in response to a biological or chemical attack.
In a move that could significantly alter the future of genetic medicine and the industry around it, a US District Court judge invalidated seven patents for human genes linked to breast and ovarian cancer, on the grounds that genes are discovered, not created. The ruling opens up challenges against the patents held by numerous companies on thousands of human genes, and jeopardizes an industry business model based on exclusive rights to gene treatment.
Today the Federal Communications Commission unveiled its plan to expand broadband Internet access to 100 million more Americans within the next five years. The plan calls both for the expansion of wired networks in under-serviced areas, and for the dedication of more wireless spectrum for Internet use as opposed to television. Largely deficit-neutral, the plan has bipartisan support in the current Congress, in part because contentious issues of net neutrality and privacy were not tackled by the FCC's plan. As you remember, PopSci called for an improvement to the nation's broadband infrastructure last year
Ever since prehistoric man first set fires to drive game towards hunters and cliffs, humans have altered their environment for their own gain. No more so than in the years since the Industrial Revolution, when carbon emissions began to drastically alter Earth's climate and atmosphere. And now that we know definitively that humans can alter Earth's climate, some scientists have begun investigating ways to deliberately change the weather to offset the negative impact of a century of inadvertent human generated climate change.
How long does it take the Earth to revolve around the sun? Did the earliest humans and dinosaurs live at the same time? What percentage of the Earth’s surface is covered with water? Think you know the answers? Well, if you’re an American adult you may be frighteningly alone.
Call it the "green" team or even the "dream" team, but what environmentalists can now say with affirmation is that change really is here. President-elect Barack Obama's picks for his administration's green team are among the best and brightest scientists and advocates of environmental change.
The backlash to the Science Debate movement has begun

The idea that a presidential debate focused on science will advance the cause of science "is more magical thinking than scientific," according to a new essay by David Goldston in the journal Nature. Momentum around such a debate has been growing since December, when a grassroots, nonpartisan group called Science Debate 2008 started a petition that called for a "public debate in which the U.S. presidential candidates share their views on the issues of The Environment, Medicine and Health, and Science and Technology Policy." The petition now has many thousand signatories [full disclosure: they include both myself and the editor-in-chief of Popular Science, a.k.a. my boss].
Tight on funds, NASA cuts key science programs to foot the bill for manned missions to space

In July, the space shuttle Discovery is slated to deliver two tons of hardware and supplies to the partially built International Space Station. This mission is paid for. As for the 16 more needed to finish assembly, as mandated by President George W. Bush two years ago in his Vision for Space Exploration policy, NASA is short by as much as $5 billion.
