USGS: Sandy will erode many Atlantic Coast beaches
Nearly three quarters of the coast along the Delmarva Peninsula is very likely to experience beach and dune erosion as Hurricane Sandy makes landfall, while overwash is expected along nearly half of the shoreline; the predictions of coastal change for the Delaware, Maryland, and Virginia peninsula is part of a larger assessment of probable coastal change released by the U.S. Geological Survey (USGS)

Hurricanes will test Florida buildings, built under new, post-Wilma building codes
In 2005 Hurricane Wilma was responsible for five deaths and millions of dollars worth of damage in Florida; building codes in the state were updated, and experts predict that these new buildings, most of which were designed with wind-tunnel testing, should perform well in all but the most severe conditions

Human activity can trigger an earthquake
Earthquakes occur when tectonic plates try to move past each other, and the friction between them holds them in place; the friction creates energy which builds up, and when the plates move past each other, the energy is released, triggering an earthquake; fracturing increases the fluid pressure inside faults; this increased pressure, in turn, lowers the stress threshold for triggering an earthquake enough for one to take place

Smart camera to describe what it sees -- and reason about what it cannot see
Army scouts are commonly tasked with covertly entering uncontrolled areas, setting up a temporary observation post, and then performing persistent surveillance for twenty-four hours or longer; what if instead of sending scouts on high-risk missions the military could deploy taskable smart cameras? A truly “smart” camera would be able to describe with words everything it sees and reason about what it cannot see

Thawing permafrost to release nitrogen, carbon – doubling the amount of carbon in the atmosphere today
As much as forty-four billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost, or frozen ground, could be released into the environment as the region begins to thaw over the next century as a result of a warmer planet; for context, this is roughly the amount of carbon stored in the atmosphere today

U.S. East Coast braces for Sandy
Residents along the U.S. Atlantic coast, from North Carolina to Maine, were bracing form Hurricane Sandy landfall; people began to evacuate certain areas, while in many other places school closures were announced and supplies were quickly disappearing from stores’ shelves; public transit services were suspended Sunday evening, and more than 3,000 flights canceled; the hurricane may be especially ferocious because it was on its path to meet a winter storm and a cold front, together with high tides from a full moon

Asteroid DA14 will be whizzing by Earth on 15 February -- the closest asteroid fly by in history
On 15 February 2013, asteroid 2012 DA14, the size of a city block, will be whizzing within 14,000 miles of Earth, squeezing between Earth’s atmosphere and the geostationary satellites orbiting the planet; it will be the closest asteroid fly by in history; experts say there is no chance the asteroid will hit Earth — this time; with more than 4,700 asteroids NASA has identified as potential threats to Earth, however, some as big as sixteen football fields, these objects are getting a lot of attention

Paintballs may deflect an incoming asteroid
With twenty years’ notice, paint pellets could cause an asteroid to veer off course; researchers say that, if timed just right, pellets full of paint powder, launched in two rounds from a spacecraft at relatively close distance, would cover the front and back of an asteroid, more than doubling its reflectivity, or albedo; the initial force from the pellets would bump an asteroid off course; over time, the sun’s photons would deflect the asteroid even more

U.S. shale gas drives up coal exports – and CO2 emissions
U.S. CO2 emissions from domestic energy have declined by 8.6 percent since a peak in 2005, the equivalent of 1.4 percent per year; researchers warn, however, that more than half of the recent emissions reductions in the power sector may be displaced overseas by the trade in coal

Understanding the effects of Fukushima by studying fish
Japan’s “triple disaster,” as it has become known, began on 11 March 2011, and remains unprecedented in its scope and complexity; to understand the lingering effects and potential public health implications of that chain of events, scientists are turning to a diverse and widespread sentinel in the world’s ocean: fish; the data from Japan fisheries provide a look at how the ocean is faring eighteen months after the worst accidental release of radiation to the ocean in history

Safety glass – cut to any shape
If an object slams into the glass façade of a high-rise building, the glass must not shatter and fall down, because it could harm pedestrians below; in addition, the window panes must hold if a person were to fall against it from the inside; architects and builders must therefore use something stronger than laminated safety glass on the façades of high rise buildings; scientists develop a method which offers more flexibility with the design and handling of safety glass

Scientists improving process to recycle rare-earth materials
Recycling keeps paper, plastics, and even jeans out of landfills. Could recycling rare-earth magnets do the same? Perhaps, if the recycling process can be improved; scientists are working more effectively to remove the neodymium, a rare earth element, from the mix of other materials in a magnet; initial results show recycled materials maintain the properties that make rare-earth magnets useful

The long view
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
A Brief History of Federal Funding for Basic Science
Biomedical science in the United States is at a crossroads. For 75 years, the federal government has partnered with academic institutions, fueling discoveries that have transformed medicine and saved lives. Recent moves by the Trump administration — including funding cuts and proposed changes to how research support is allocated — now threaten this legacy.

The United States since its founding has always been a technological republic, one whose place in the world has been made possible and advanced by its capacity for innovation. But our present advantage cannot be taken for granted.
Autonomous Weapon Systems: No Human-in-the-Loop Required, and Other Myths Dispelled
“The United States has a strong policy on autonomy in weapon systems that simultaneously enables their development and deployment and ensures they could be used in an effective manner, meaning the systems work as intended, with the same minimal risk of accidents or errors that all weapon systems have,” Michael Horowitz writes.
Ukraine Drone Strikes on Russian Airbase Reveal Any Country Is Vulnerable to the Same Kind of Attack
Air defense systems are built on the assumption that threats come from above and from beyond national borders. But Ukraine’s coordinated drone strike on 1 June on five airbases deep inside Russian territory exposed what happens when states are attacked from below and from within. In low-level airspace, visibility drops, responsibility fragments, and detection tools lose their edge. Drones arrive unannounced, response times lag, coordination breaks.
