BIG Wrap

Wi-Fi frag attacks put all mobile device users at risk

Recent studies have shown that all contemporary security protocols leave mobile device users vulnerable to Wi-Fi fragmentation and aggregation attacks – or frag attacks, reports Tech Xplore. Research indicates that while the design flaws may prove more challenging to abuse due to the need for user interaction or uncommon network settings, the vulnerabilities related to programming pose a more significant risk. Researchers revealed that the flaws originated with some of the first Wi-Fi protocol back in...

Study of 70,000 gives us Reason #187,568 to quit smoking … but impaired brain might prevent us from remembering to do it

In the largest study of the associations between smoking and cardiovascular disease on cognitive function, researchers at the Translational Genomics Research Institute found that both impair the ability to learn and memorize, and that the effects of smoking are more pronounced among females, while males are more impaired by cardiovascular disease, reports Medical Xpress. By analyzing data from more than 70,000 individuals worldwide, the study produced results that indicate definitive trends. "These results suggest that smoking...

Batch reverse osmosis’ could be transformative in producing fresh water, say Purdue engineers

Purdue University engineers have developed a "batch reverse osmosis" process that promises better energy efficiency, longer-lasting equipment and the ability to process water of much higher salinity, Tech Xplore reports. It could end up a difference maker in water security around the world. Reverse osmosis is used in many countries; in arid places such as the Middle East, more than half of the fresh drinking water supplies come from desalination facilities. "About a third of the lifetime cost of...

Scar faces stiff tests as robotic dog fetching data

Deep underground in eastern France, a four-legged bundle of energy named Scar, loaded with sensors, steps gingerly through vast caverns. It's an ideal training ground for the robotic dog being groomed by researchers at the Ecole des Mines engineering school, reports Tech Xplore. On Tuesday, a team from the university tested out Scar's abilities at the Cigeo lab 500 metres below the village of Bure, slated to become a permanent home for thousands of tonnes...

‘Thank you, Professor Rima Azar, for picking Canada as your home. I apologize for some of the tenants’

If there is a more eloquent journalist in Canada than Rex Murphy, I welcome your nominations. In his piece in the National Post today, Rex tells the story of a movement gone too far.   https://nationalpost.com/opinion/rex-murphy-when-the-woke-come-for-conservatives-of-colour

MIT researchers blowing the whistle on fouling

Fouling of filtration membranes used in desalination and separating of dairy products occurs when particles get deposited on the filter over time, clogging the system and limiting its effectiveness and efficiency. Efforts to clean, or de-foul, these membranes have typically relied on chemical processes, which result in losses in productivity and profit while raising environmental and workplace safety concerns associated with waste disposal. A team of researchers from the MIT Department of Mechanical Engineering has found...

Colonial Pipeline shutdown and looming Line 5 disruption could result in price bump at the pump

A cyberattack that knocked out the main oil pipeline supplying the U.S. Eastern Seaboard and the potential shutdown of a major Canadian conduit could send fuel prices soaring, the Financial Post reports  The outage on the Colonial Pipeline could be exacerbated by a Michigan state order forcing Enbridge Inc.’s Line 5 pipeline — supplying oil to Michigan, Ohio, Ontario and Pennsylvania refineries — to shut down on Wednesday, which could further strain U.S. oil...

Examining the science of motherhood

Abigail Tucker’s article in Smithsonian Magazine is a fascinating look at how offspring affect their mothers’ hearts and brains in deep and enduring ways. New research sheds light on why hearts of recently delivered human mothers have shown a remarkable ability to recover from cardiac events. In tests on mice at Mount Sinai Hospital lab, cardiologist Hina Chaudhry and her research team discovered something astonishing: heart cells with DNA that doesn’t match the mother’s own. The...

Study indicates most animals are totally cool with getting it on with close relatives

When given a choice, animals rarely avoid mating with their cousins or siblings, according to a new study published in the journal Nature Ecology & Evolution. The study was a meta-analysis that collected and analysed information from 139 studies on mate choice, conducted over 40 years looking at 88 different species, from fruit flies to chimpanzees, CBC reports. Canadian researcher John Fitzpatrick, an associate professor of zoology at Stockholm University, told Quirks & Quarks host Bob McDonald that he was motivated to understand...

Major U.S. pipeline shut down by cyberattack

A cyberattack has taken down the main pipeline that carries gasoline to the U.S. East Coast, elevating concern about how vulnerable critical systems are to hacking assaults, reports CNET. Colonial Pipeline, which operates pipes that carry refined petroleum products said in a statement that it has taken "certain systems offline to contain the threat, which has temporarily halted all pipeline operations, and affected some of our IT systems." It is unclear whether criminal hackers...
