Ever stricter security measures in place in U.S. airports is making air travel less safe and airports more vulnerable, according to University of Illinois mathematics professor Sheldon H. Jacobson. The reason is too many resources are spent screening passengers who pose little risk, which steals time and money away from identifying real threats.
“A natural tendency, when limited information is available about from where the next threat will come, is to overestimate the overall risk in the system,” says Jacobson in a press release. “This actually makes the system less secure by over-allocating security resources to those in the system that are low on the risk scale relative to others in the system.”
Jacobson recommends airports work to distinguish high-risk from lower-risk passengers before subjecting every flier (and all that baggage) to zealous screening. More programs like the TSA’s Pre-Check, which expedites screening for eligible passengers by rating their risk against that of entire flying population, would help airports perceive security threats more accurately. His recently published paper also explores scenarios to expose security gaps.

Addressing Passenger Risk Uncertainty for Aviation Security Screening by Adrian J. Lee and Sheldon H. Jacobson, Transportation Science (December 2011)
Rising socioeconomic inequality is one of the major risk factors portending an insecure future, warn researchers for the Organization for Economic Cooperation and Development (OECD). In a new report, OECD economists outline several policy proposals for reducing Europe’s wealth and income gap while simultaneously boosting economic growth.
First, the report recommends that governments adjust tax and benefits systems to promote “growth in the middle” i.e., reform tax codes that favor the wealthy, thus enabling tax burdens on struggling middle-income taxpayers to be reduced.
The 25% wage gap between temporary and permanent workers could also be reduced by offering more protections for temporary workers. Women’s labor-force participation could be increased with the provision of more affordable child care. And improving educational opportunities and outcomes for immigrants and disadvantaged groups will have long-term benefits to the economy, such as enhancing the quality of the labor force, according to the report.
“The main challenge facing governments today is implementing reforms that get growth back on track, put people to work and reduce the widening income gap,” concludes OECD chief economist Pier Carlo Padoan.
People in the path of a tornado don’t typically know it’s coming until minutes before it arrives. But a new tornado prediction model could give them as much as a month or more of prior notice.
The model’s debut is particularly timely, as climate experts expect climate warming to intensify tornado activity. U.S. deaths due to tornado activity last year exceeded all tornado-related deaths for the prior 10 years combined. It is not conclusive that global warming is to blame, but the index’s authors hope that their model could help researchers find out for sure.
Meanwhile, NOAA tornado expert Harold Brooks is optimistic that the index will minimize future injuries and deaths. With advance warning, communities and relief agencies will have time to gather needed supplies, he says.

Researchers at IBM have succeeded in encoding data in just 12 magnetic atoms, an enormous improvement over conventional disk drives that use as many as 100 atoms to store a single bit of Information. The accomplishment could lead to future breakthroughs in nanocomputation and computer efficiency.
To make it happen, the IBM team had to look beyond the traditional silicon transistor and get specially magnetized atoms to “hold” information by spinning in one of two directions, to represent either ”1” or “0.”
“The chip industry will continue its pursuit of incremental scaling in semiconductor technology but, as components continue to shrink, the march continues to the inevitable end point: the atom. We’re taking the opposite approach and starting with the smallest unit — single atoms — to build computing devices one atom at a time, ” said project leader Andreas Heinrich in a press release.
The World Future Society will publish a collection of essays in conjunction with WorldFuture 2012: Dream. Design. Develop. Deliver, to be held July 27-29, 2012, in Toronto.
This collection will be published in a special edition of World Future Review, the journal of the Society’s Professional Membership program, and will be made available to all conference registrants.
Deadline for completed papers is February 20, 2012.
