Solar energy conversion breakthrough
Scientists say that sunlight falling on only 9 percent of California’s Mojave Desert could power all of the U.S. electricity needs — if the energy could be efficiently harvested; this is a big “if,” since current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications; Northwestern University researchers show a way to increase solar cell efficiency

DOE, partners test commercial geothermal technology in Nevada
Geothermal energy attracts more and more attention, and for good reason: One cubic kilometer of hot granite at 250 degrees centigrade has the stored energy equivalent of 40 million barrels of oil

TSA lab's new concept in airport security: Tunnel of Truth
Futuristic vision of airport security would see passengers stand on a conveyor belt moving under an archway as different sensors scan them for weapons, bombs, and other prohibited items; no need to take the shoes off; by the time they step out of the tunnel, they have been thoroughly checked out

Cleaner water through nanotechnology
As global warming causes more and more countries to have less and less fresh water for human consumption and irrigation, the purification and re-use of contaminated water becomes more urgent; Aussie researchers offer a nanotechnology-based method to purify water which is more effective and cheaper than conventional water purification methods

Protecting against cosmic radiation effects on aviation microelectronics
Cosmic radiation has a deleterious effect on aviation microelectronics — the effect on circuitry is 300 times greater at high altitude than at ground level, creating a potential risk to civil and military aircraft; U.K. scientists accelerate the effects of cosmic radiation so they can replicate the effect of thousands of hours of flying time in just a few minutes

King coal, II: Administration restructures approach to clean coal funding
DOE restructures FutureGen approach; under the new plan, DOE’s investment would provide funding for no more than the carbon capture and storage (CCS) component of the power plant — not the entire plant construction; the original 2003 FutureGen concept called for the federal government to cover 74 percent of the cost of the entire project; DOE requests $648 million in FY2009 budget for coal research, development, and deployment

The long view
Building Trust into Tech: A Framework for Sovereign Resilience
Governments are facing a critical question: who can be trusted to build and manage their countries’ most sensitive systems? Vendor choices, for everything from cloud infrastructure to identity platforms, are no longer just commercial; they are strategic.
Researchers Unveil First-Ever Defense Against Cryptanalytic Attacks on AI
Security researchers have developed the first functional defense mechanism capable of protecting against “cryptanalytic” attacks used to “steal” the model parameters that define how an AI system works.
Data Centers’ Insatiable Demand for Electricity Will Change the Entire Energy Sector
When the first large language models were unleashed, it triggered a headache for authorities around the world as they tried to figure out how to satisfy data centers’ endless demand for electricity.
