Circa 2015


The Plasma Acoustic Shield System (PASS) is a crackling, flashing wall of light hanging in the air up to 100 meters away. And while it’s the stuff of sci-fi, the laser-powered PASS already exists in prototype form, built by Stellar Photonics of Redmond, Wash., with funding from the Pentagon’s Joint Nonlethal Weapons Directorate (JNLWD).

Perfectionism often develops in childhood, is impacted by parenting and can lead to mental health struggles in later life. Credit: Shutterstock We recently conducted one of the largest-ever studies on perfectionism. We learned that perfectionism has increased substantially over the past 25 years and that it affects men and women equally.

We also learned that perfectionists become more neurotic and less conscientious as time passes.

Perfectionism involves striving for flawlessness and requiring perfection of oneself and others. Extremely negative reactions to mistakes, harsh self-criticism, nagging doubt about performance abilities and a strong sense that others are critical and demanding also define the trait.

New data predicts an “empty planet.”


But a new book examines the data and comes to a radically different conclusion: instead of continuing to rise, the population will level out in about 30 years — and then start to decline, possibly forever.

Stand on Zanzibar

The book is called “Empty Planet,” and it was written by journalist John Ibbitson and political scientist Darrell Bricker. Their key argument: access to information is changing people’s outlook on reproduction around the world and rapidly shifting the old norms around families and fertility.

New York: Researchers say they have developed an innovative new system for delivering a malaria vaccine that shows promise in its effectiveness. By developing a vaccine that targets specific cells in the immune system, researchers from the University of Chicago in the US saw a much greater immune and antibody response to the vaccine.

Though a vaccine for malaria exists, it is only effective in 30 to 50 per cent of patients, and malaria is still responsible for nearly 500,000 deaths annually, according to the US Centers for Disease Control. “When compared to the current malaria vaccine option, our results are extremely exciting,” said Jeffrey Hubbell, a professor at the University of Chicago.

Researchers at the University of South Carolina in Columbia have demonstrated an experimental plasma device capable of cleaning gas samples of D4, one of the most common siloxanes. Drawing on a technique for creating plasma called dielectric barrier discharge, the group was able to significantly reduce the amount of D4 samples after treating it with a helium-based plasma.

The findings point to a new potential solution for accommodating landfill gas rich in siloxanes. They will be presented at the American Physical Society 71st Annual Gaseous Electronics Conference and 60th Annual meeting of the APS Division of Plasma Physics, which takes place Nov. 5–9 at the Oregon Convention Center in Portland.

“This is the first time dielectric barrier discharge has been used to remove volatile organic silicate compounds,” said Malik Tahiyat, one of the researchers involved with the study. “In our case, there’s no wait for removing it or material that has to be thrown out after a certain amount of time.”
