NASA to use asteroid flyby to test planetary defense network
For the first time, NASA will use an actual space rock for an observational campaign to test NASA’s network of observatories and scientists who work with planetary defense. The asteroid, named 2012 TC4, does not pose a threat to the Earth, but NASA is using it as a test object for an observational campaign because of its close flyby on 12 October 2017.

Troubled flood insurance program traps homeowners in flood-prone areas
The U.S. flood insurance program has repeatedly rebuilt some of the most flood-prone properties in the country, unintentionally setting a trap for owners of modest homes who would prefer to move out of harm’s way, according to a new national report. Today it is thousands of properties, but climate change and rising sea levels threaten to flood millions of properties in the coming decades. For every $100 the nation spends to rebuild homes with national flood insurance funds, FEMA spends just $1.72 to better protect people by moving them to safer, less flood-prone land.

Shifting storms threaten once placid areas with extreme waves, extensive damage
The world’s most extensive study of the impacts of coastal storm fronts in a changing climate has found that rising seas are no longer the only threat. The study of a major storm front striking the coast has revealed a previously unrecognized danger from climate change: as storm patterns fluctuate, waterfront areas once thought safe are likely to be hammered and damaged as never before.

A “cocktail” of geoengineering approaches to combat climate change
Geoengineering is a catch-all term that refers to various theoretical ideas for altering Earth’s energy balance to combat climate change. New research from an international team of atmospheric scientists investigates for the first time the possibility of using a “cocktail” of geoengineering tools to reduce changes in both temperature and precipitation caused by atmospheric greenhouse gases.

Hawaii launches a campaign to prepare islanders for North Korean nuclear attack
Officials in Hawaii are preparing for a North Korean nuclear attack. State officials said they would not want to create a panic among the islanders, but that the right thing to do under the circumstances was to have the Hawaii Emergency Management Agency unveil a public education and information campaign aiming to inform people what to do in the event Pyongyang launched a nuclear-tipped missile targeting Hawaii.

Soft, growing robot for searching people under collapsed buildings
Imagine rescuers searching for people in the rubble of a collapsed building. Instead of digging through the debris by hand or having dogs sniff for signs of life, they bring out a small, air-tight cylinder. They place the device at the entrance of the debris and flip a switch. From one end of the cylinder, a tendril extends into the mass of stones and dirt, like a fast-climbing vine. A camera at the tip of the tendril gives rescuers a view of the otherwise unreachable places beneath the rubble. This is just one possible application of a new type of robot – a robot that can grow across long distances without moving its whole body.

Search and rescue dogs perform well despite travel stress
When disaster strikes, you want the very best tools, functioning at their peak. In the case of catastrophic earthquakes, tornadoes, or even bombings in war zones, those tools are search and rescue dogs. But researchers have found that getting dogs to disaster sites can add to the animals’ stress. search and rescue dogs fly on a moment’s notice to the site of a disaster, where they are expected to perform at the top of their game. But, just like for humans, flying can be stressful for dogs.

Making flood forecasting easier, faster
Floods and tornadoes are the deadliest disasters in the world. In the United States alone, approximately eighty lives are lost every year due to flood related incidents. In addition to the loss of lives, the nation loses billions of dollars in property damage and spends billions on recovery and rebuilding efforts every year. With the help of the Internet of Things (IoT) and early alerts and warnings technology, flood forecasting is not impossible.

20-story earthquake-safe buildings made from wood
Engineering researchers are putting a two-story wooden structure through a series of powerful earthquake simulations, using a lab shake table. The goal is to gather the data required to design wood buildings as tall as twenty stories that do not suffer significant damage during large earthquakes.

Building to better weather the storm
The Atlantic hurricane season has officially begun and the National Oceanic and Atmospheric Administration (NOAA) is predicting “above normal” storm activity this year. That could mean significant damage to coastal communities — some of which are still recovering from last year’s hurricane season. New dashboard developed by the MIT Concrete Sustainability Hub helps builders calculate the breakeven cost of hazard mitigation in hurricane-prone areas.

Dust Bowl redux: Increase in dust storms in the U.S.
Could the storms that once engulfed the Great Plains in clouds of black dust in the 1930s once again wreak havoc in the United States? A new statistical model developed by researchers predicts that climate change will amplify dust activity in parts of the United States in the latter half of the 21st century, which may lead to the increased frequency of spectacular dust storms that have far-reaching impacts on public health and infrastructure.

Cyberattack could cost $120 billion: Lloyd’s
Insurance giant Lloyd’s of London has warned that the cost of a serious cyberattack to the global economy could reach $120 billion or more – which was the cost of damage inflicted by Hurricanes Katrina or Sandy. insurance firm says the threat posed by global cyberattacks has spiraled, and that it poses a huge risk over the next decade to business and governments everywhere. Trevor Maynard, Lloyd’s head of innovation and co-author of the report, said that where people are involved, risk changes quite rapidly — from cyberattacks to terrorism and political risk – but that from year to year, such risks vary relatively little. “But climate change in the end will be far larger as a risk,” he said, and it remains the biggest challenge in the long run.

Climate change to deplete some U.S. water basins, reduce irrigated crop yields
A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation. The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this region is projected to experience reduced precipitation by midcentury. Less rainfall to the area will mean reduced runoff into water basins that feed irrigated fields.

We worked out what it would take to wipe out all life on a planet – and it’s good news for alien hunters
Earth has undergone at least five mass extinctions in its history. It’s long been thought that an asteroid impact ended the dinosaurs. As a species, we are rightly concerned about events that could lead to our own elimination – climate change, nuclear war or disease could wipe us out. So it’s natural to wonder what it would take to eliminate all life on a planet. There are many events, both astrophysical and local, that could lead to the end of the human race. Life as a whole, however, is incredibly hardy. As we begin our search for life away from Earth, we should expect that if life had ever begun on a planet, some survivors might still be there.

Extreme coastal sea levels more likely
Extreme sea levels are typically caused by a combination of high tides, storm surges, and in many cases waves, Wahl said. When an extreme event collides with continually rising seas, it takes a less intense storm, such as a Category I hurricane, to inflict as much coastal damage as a Category II or III storm would have had when the seas were lower. Because of the rising sea levels, which research has confirmed has occurred steadily during the past century and is expected to accelerate in the future, extreme events that are now expected to happen, on average, only once every hundred years, could occur every decade or even every year, in many places by 2050, the study said.
