• Without water reform Asia will face food shortage by 2050

    There are three options for meeting the food needs of Asia’s population, which will expand by one-and-a-half billion people over the next forty years: The first is to import large quantities of cereals from other regions; the second to improve and expand rainfed agriculture; and the third to focus on irrigated farmlands

  • Massive earthquakes shake scientific thought

    Experts who dismissed notions that far-away quakes could be linked are beginning to think again after huge tremors rocked Samoa and Indonesia on the same day, followed by another major convulsion in Vanuatu

  • New Bay Bridge span designed to endure major quake

    Twenty years ago a 250-ton section of the Bay Bridge fell into the water as a result of a 6.9 magnitude earthquake; the new bridge design will be able to withstand the largest plausible earthquake to occur within a 1,500-year period

  • Asteroid collision: How to defend Earth, II

    Asteroid impacts are much rarer than hurricanes and earthquakes, but they have the potential to do much greater damage; moreover, what if an asteroid hits Earth in the Middle East or the Asian subcontinent? Such an event could be misinterpreted as a nuclear attack — both produce a bright flash, a blast wave, and raging winds; the result may be a nuclear war

  • How high is the risk of civilization-killing asteroids?

    Planetary bombardments: scientists at a planets meeting discuss the risks of an asteroid colliding with Earth; researchers are worried about asteroid Apophis, which will come uncomfortably close to Earth on 13 April 2029; one scientist said that “It’s 10 times more likely that an unknown asteroid will slam into us from behind while you’re looking at Apophis”

  • Asteroid collision: How to defend Earth, I

    There are thousands of Near Earth Objects (NEOs) orbiting Earth; some of them are of a civilization-ending size, others are smaller — they will take out “only” a country or a city were they to collide with Earth; scientists say we should focus our minds on this danger

  • Is California's Big One coming?

    In 1992 and in 2004, remote earthquakes caused changes to the San Andreas fault; in both cases, there were distinct changes in the movement of fluids and an increase in the frequency of micro-earthquakes deep within the fault below Parkfield; what will be the effect on the fault of the recent Sumatra earthquake?

  • Corps asked to scrap floodgate plans in Belle Chasse, Louisiana

    There is a debate in Louisiana about the best way to protect homes in the Jesuit Bend area: the Army Corps of Engineers wants to build a floodgate — but this would leave some 1,400 homes unprotected; residents prefer an 8-mile levee

  • New Orleans storm pumps do not protect city

    The Army Corps of Engineers quickly installed new storm control pumps in New Orleans in the months after Katrina; trouble is, these pumps do not protect the city, the the Corps could have saved $430 million in replacement costs by buying proven equipment

  • How life will survival in a post-apocalypse blackout

    What if asteroid impacts, massive volcanic eruptions, or large-scale wildfires were to plunge our planet into abnormal darkness” It happened several times in the past; life will continue with a little help from organisms that can switch to another source of energy while they wait for sunlight to pierce the darkness once more

  • Mega-quake could strike near Seattle

    New study shows that two massive tectonic plates colliding 25 miles or so underneath Washington state’s Puget Sound basin; findings suggest that a mega-earthquake could strike closer to the Seattle-Tacoma area, home to some 3.6 million people, than was thought earlier

  • "Active cloak" protects buildings from earthquakes

    Researchers say real objects could be cloaked by active cloaking — which means the technology uses devices that actively generate electromagnetic fields rather than being composed of “metamaterials” (exotic metallic substances) that passively shield objects from passing electromagnetic waves

  • NASA short on funds to keep up with killer asteroids

    NASA is charged with seeking out nearly all the asteroids that threaten Earth; trouble is, it does not have the money to do the job

  • Universities, businesses offer solutions for dealing with hurricanes

    Three universities are busy offering solutions which better predict hurricanes and cope with the damage they cause; a Bill Gates-supported company is more ambitious: it proposes to kill hurricanes by placing giant ocean-going tubs in the paths of storms

  • Predicting hurricanes

    Researchers developed a new computer model that they hope will predict with unprecedented accuracy how many hurricanes will occur in a given season
