New material dramatically increases explosive force of weapons
A revolutionary material that will replace steel in warhead casings will bring added lethality and increase the likelihood of a hit on an enemy target; by combining several metals with standard manufacturing techniques, High-Density Reactive Material (HDRM) has the potential dramatically to increase the explosive impact of most weapons with little or no compromise in strength or design

Reversing metabolism to make biofuels at breakneck pace
Engineers reverse E. coli metabolism for speedy production of fuels, chemicals; a Rice University’s team reversed one of the most efficient of all metabolic pathways — the beta oxidation cycle — to engineer bacteria that produce biofuel at a breakneck pace

Self-assembled "micro-robots" designed
Tiny micro-robots — just half a millimeter wide — assemble themselves into star shapes when an alternating magnetic field is applied; the robots can pick up, transport, and put down other non-magnetic particles — potentially enabling fabrication of precisely designed functional materials in ways not currently possible

Storing CO2 underground to extract electricity
A team of scientists, led by the Berkeley Lab, hopes to become the first in the world to produce electricity from the Earth’s heat using CO2; They also want permanently to store some of the CO2 underground, where it can not contribute to climate change

Undergraduate student overcomes major hurdle to invisibility cloak
An undergraduate student has overcome a major hurdle in the development of invisibility cloaks by adding an optical device into their design which not only remains invisible itself, but also has the ability to slow down light; the innovation open up the possibility for a potential invisibility cloak wearer to move around amongst ever-changing backgrounds of a variety of colors

Towing icebergs to provide fresh water for parched regions
A third of the world’s population — more than two billion people — lives without access to clean drinking water, and studies show that the situation will only get worse; a French innovator has an idea: towing icebergs from the Greenland and Antarctica to regions most in need of fresh water; a computer simulation shows this solution to be viable and affordable

Solar-based method to provide safe water
A revolutionary low-cost technique that uses sunshine to provide safe drinking water; solar disinfection (SODIS) of drinking water is an effective way of preventing water-borne diseases such as cholera, dysentery or polio — especially important in developing countries, where safe drinking water is often a precious rarity

U Maryland students design record-breaking helicopter
University of Maryland students flew past a world record after their human-powered helicopter hovered more than twelve seconds inside a campus building; the team’s goal is to win the Sikorsky Prize, a $250,000 reward given by the American Helicopter Society; in order to win, a human-powered helicopter must fly at least thirty seconds, hover at least three meters above ground, and not drift outside a ten-meter square

Beachball-like observation UAV developed
A beach ball-size drone can fly down narrow alleys, hover on the spot, take off vertically, bounce along the ground like a soccer ball — all the time transmitting live images from a video camera; it can travel above traffic or spy on a target through a window — and can also be used in search and rescue in disaster zones, where it could fly through buildings and even up and down stairways

Innovative biosensor for rapid virus field tests
Relying on a novel DNA-based bio-chemo-physical conversion method, a new bio-detection device is able to detect harmful bacteria, such as E. coli, salmonella, and staphylococcus, on site, within thirty minutes; it can be adapted to cover such deadly viruses as SARS, H5N1 flu, and swine flu viruses; it can also be designed to monitor possible biological attack from anthrax, smallpox, cholera, and more

Making runways safer
Airplanes undergo significant stresses during take-off and landing, and parts often become detached, putting subsequent runway users at risk; until now, airport staff have had to monitor runways without technical assistance — an activity that is prone to errors; a new radar system is set to increase safety at airports

New device identifies unknown liquids instantly
Materials scientists and applied physicists have invented a new device that can instantly identify an unknown liquid; the 3D-nanostructured chip offers a litmus test for surface tension (and doubles as a carrier for secret messages); the researchers are currently developing more precisely calibrated chips and conducting field tests with government partners for applications in quality assurance and contaminant identification

Listening to the sound of bullets
ShotSpotter systems relies on a system of acoustic sensors to identify the location from which a shot has been fired; the alerts are immediately conveyed to police dispatchers, 911 operators, and sometimes to officers in the field via laptops in patrol cars; the system includes a computer program which displays a comprehensive bird’s-eye view of the area, marking the location of the incident with a red dot and indicating the time and number of rounds fired

Blast gauge gives medics, doctors critical information
Researchers are working to enhance the safety of soldiers in the field through the development of a device that monitors the physical impacts of exposure to an explosive blast; 188,270 service members have suffered a traumatic brain injury in the last decade; the extent of injury is often difficult to discern, making diagnosis and selection of appropriate medical treatment challenging
