Bringing Sunlight Inside
Photovoltaic panels have a
new design: concentric
circles that focus the sun's
rays on miniaturized
modules. Having the panels
automatically sense sunlight
and turn towards it also

De-Bugging Your Food
A physical chemist has
developed a new technique
for ridding harvested
produce of insect pests and
microorganisms without using
pesticides such as methyl
bromide. The technique,
called Metabolic Stress

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
Mechanical Engineers' Device Helps Electricity Conservation
Smart meters are small computers that provide real-time information on how much electricity is being used by each customer and when, and can relay information back to the head office over the very ... > more -
Mechanical Engineering Students Develop High-Altitude Reconnaissance Airships
On a shoestring, and with off-the-shelf components, students are designing prototypes of robotic blimp that could one day be used by the Pentagon. Cheaper than spy satellites, blimps can hover in ... > more -
Engineers Test Ventilated Seats And Thermal-Acoustic System To Make A/C Energy-Efficient
Engineers at a national lab have shown that small fans embedded in car seats could help cool passengers down -- saving up to 7 percent of the 30 to 40 gallons of gasoline per year an average driver ... > more -

Energy Scientists Propose Color-Coding Standard for PC Sleep Mode
Different computers use different indicator lights to signal that they are in energy-saving, or "sleep" mode. Users are often unsure if their PC is truly saving energy, rather than just turning its ... > more -
Vascular Surgeons Lower Blood Pressure with Implanted Device
A new cell phone-sized implant can keep blood pressure in check from within the chest, just like a pacemaker controls heartbeats. When the device detects a rise in pressure, it sends electrical ... > more
