Government lockdowns may have been terrible for diagnosing disease and the mental health of kids but it reduced terrorism, according to a new paper. If no one can travel, government agents helping fifth columnists do their damage are useless. When the pandemic struck, terrorists vowed to increase their attacks and create a tipping point but that did not happen.

Instead, government-imposed curfews and travel bans instituted to protect public health in Iraq, Syria, and Egypt were significantly associated with a reduction in ISIS attacks, especially in urban areas and locations near their bases of operations. It likely meant fewer attacks by al-Qaeda, and Boko Haram also.

Superionic materials, needed for solid-state electrolytes that could replace the liquid organic electrolytes in current electric car batteries and make them safe for mass usage, face challenges in going from conception to production.

Lithium ions are very mobile at ambient temperatures in solid-state ionic conductors, and that means atoms do not simply vibrate around their equilibrium positions. Disorder is bad in production systems. 

Until Alfred the Great managed to isolate and contain invaders from Scandinavia, Lyminge, a monastery in Kent, was on the front line of long-running Viking hostility.

Lyminge endured repeated attacks for almost a century through effective defensive strategies, University of Reading archaeologists now say. Despite being in a region of Kent which bore the full brunt of Viking raids in the later 8th and early 9th centuries, they survived. rebuilt, and recovered more completely than historians previously thought.

Stimuli-responsive polymers will bring next-generation small-scale, wirelessly controlled soft-bodied robots.

Even now, these materials have made robots that can walk, swim and jump. Now, a FAIRY can even fly. FAIRY is the nickname of the Flying Aero-robots based on Light Responsive Materials Assembly program at Tampere University. It flies by wind and is controlled by light, using a soft actuator.

"The actuator is made of light-responsive liquid crystalline elastomer, which induces opening or closing actions of the bristles upon visible light excitation,” explains Hao Zeng, group leader of the project.

Since the 1960s, antioxidant supplements have been promoted as a miracle cure and that has never been true - preventing oxidation too much would be as bad as not preventing enough - but luckily few supplements make coenzyme Q bioavailable at all. Evolution created a way for the energy factories of our cells, mitochondria, to be thrown out of balance by pills.

Yet they can be thrown out of balance by nature. Coenzyme Q is entirely natural, and a lack of it leads to mitochondrial diseases like Leigh syndrome. But short of experimentally replacing mitochondrial DNA, it is hard to modify. For anything to change it must pass through the watery cell interior called cytoplasm to the surface of the cells in order to neutralize oxidized lipid species. 

The booster dose of either the BNT162b2 mRNA (Fosun-BioNTech, equivalent to Pfizer-BioNTech outside China) or CoronaVac (Sinovac) COVID-19 vaccine was correlated to a 90 percent reduction in death in people with multiple co-morbidities compared to 2 doses, according to a new study.
