Missing the energy-saving forest for the trees
U.K. expert says that the beneficial effects of turning off standby lights, switching from bottled to tap water, washing clothes at a lower temperature, or having car tires at the right air pressure, pale in insignificance when compared with what was happening at the supply end of energy provision

Using herd mentality for protection
New car security system acts as a herd of animals in the wild would: cars parked next to each other on the street or parking lot serve as look-outs for each other, alerting the authorities if one of the cars is being broken into

Future weapons on display
Last week the futuristic-looking XM-25 IAWS was displayed to lawmakers; the system, still under development, will eventually be used to address the defeat of defilade targets — those targets protected by obstacles such as hills or ridges

Stretchy spider silks can be springs or rubber
Spider silk is stronger than steel and nylon, and more extensible than Kevlar; it would be ideal for personal protective gear for soldiers and law enforcement, and medical applications; “would be ideal” — because we do not yet know how to spin artificial silk; Canadian scientists have interesting ideas

Pentagon wants laser attack warnings for satellites
The U.S. economy and military capabilities are dependent on satellites for communication and information gathering; growing anti-satellite warfare capabilities — for example, by China — lead Pentagon to seek a measure of protection for space-based assets

Cheap carbon trap cleans up power station emissions
Sequestering CO2 is a good way to fight global warming, but only about 10 percent of the gas produced in the process of burning fossil fuels is CO2; most of the rest is nitrogen, which is not a greenhouse gas; there is a new, inexpensive way to separate the two

IAEA: Iran evasive about its nuclear program
Iran’s march toward the bomb continues unabated; the U.S. intelligence community may have concluded that Iran had “halted” its nuclear weapons program in 2003, but a UN atomic agency says indications are to the contrary

The long view
A Machine Learning-Based Solution May Help Firefighters Avoid Deadly Backdrafts
A lack of oxygen can reduce even the most furious flame to smoldering ash. But when fresh air rushes in, say after a firefighter opens a window or door to a room, the blaze may be suddenly and violently resurrected. Researchers have devised a plan for informing firefighters of what dangers lie behind closed doors.
A Drone Wing That Could Learn How to Sense Danger Faster
The small domes that you press on your soda’s to-go cup lid may one day save a winged drone from a nosedive. Patterns of these invertible domes on a drone’s wings would give it a way to remember in microseconds what dangerous conditions feel like and react quickly.
Battery Tech Breakthrough Paves Way for Mass Adoption of Affordable Electric Car
If new car sales are going to shift to battery-powered electric vehicles (EVs), they’ll need to overcome two major drawbacks: they are too slow to recharge and too large to be efficient and affordable. Researchers develop new technique that charges EV battery in just ten minutes.
Method for Decoding Asteroid Interiors Could Help Aim Asteroid-Deflecting Missions
Knowing how the density is distributed inside an asteroid could help scientists plan the most effective defense. For instance, if an asteroid were made of relatively light and uniform matter, a DART-like spacecraft could be aimed differently than if it were deflecting an asteroid with a denser, less balanced interior. Astronomers have found a way to determine an asteroid’s interior structure based on how its spin changes during a close encounter with Earth.
Why Not Use Space Mirrors for Reflecting Sunlight to Cool the Planet?
Given the potential consequences of climate change and a danger of reaching irreversible “tipping points,” there is an argument to be made that all options should be carefully considered. Sending giant mirrors into space to reflect solar radiation away from the Earth is one such option. The problem is that the many such geoengineering approaches have been so taboo that there is not enough information from researchers to definitively decide what options are still viable.
