Can Christmas Tree Lights Really Play Havoc With Your Wi Fi

Ofcom, the UK’s independent telephony regulator, has just released a Wi-Fi checker app for your smart phone. At the same time, it warned in its press release that your Christmas tree fairy lights could affect the quality of your Wi-Fi connection. Before the terrible jokes start and we all declare that this is a fit of “Bah Humbug!” from the telephone regulator, the warning is correct—your fairy lights could indeed be a Wi-Fi downer....

Can Zapping The Vagus Nerve Jump Start Immunity

Six times a day, Katrin pauses whatever she’s doing, removes a small magnet from her pocket and touches it to a raised patch of skin just below her collar bone. For 60 seconds, she feels a soft vibration in her throat. Her voice quavers if she talks. Then, the sensation subsides. The magnet switches on an implanted device that emits a series of electrical pulses — each about a milliamp, similar to the current drawn by a typical hearing aid....

Crime Ring Revelation Reveals Cybersecurity Conflict Of Interest

Those numbers made Internet security watchers and even some consumers sit up and take notice—people use such credentials to access banking, investment and social media accounts after all. If true, the CyberVor haul would dwarf last December’s data breach of retailer Target, in which 40 million customer credit cards were compromised. Although a New York Times story lent credibility to Hold Security’s claims, some observers question whether the cybersecurity vendor’s big reveal was more of a publicity stunt than a public service....

Firefighting Robots Go Autonomous

Firefighting, one of the nation’s most tradition-bound professions, is poised for an influx of eccentric assistants. They range from contraptions the size of a toy wagon to two-ton beasts that resemble military tanks and can blast out 2,500 gallons of water per minute. Some move on rubber tires, some on steel tracks, and some fly. All are robots. At a time when more than 3,000 Americans die in fires each year—including an average of 80 firefighters—these high-tech devices can enter burning buildings too hot for human survival....

How To Minimize Covid Risk And Enjoy The Holidays

Anthony Fauci is not celebrating Thanksgiving with his three adult daughters this year. The now famous director of the National Institute of Allergy and Infectious Diseases said in an American University Webinar that as much as he would love to spend the holiday with his kids, they had told him, “We want you and Mommy to have a nice, quiet dinner.” Fauci may be “a ‘young,’ vigorous guy,” they said, but he is also 79 years old—and that puts him in a vulnerable category for COVID-19....

In The Con We Trust A Q A With Confidence Game Author Maria Konnikova

We know con artists are out there—from psychics and Ponzi schemers to identity thieves and insurance fraudsters—and that they will surely succeed in finding their next mark. We just never think it’ll be us. But all of us are vulnerable to the wiles of the con artist, because humans have evolved to trust one another, to empathize with other people’s stories. Science writer and journalist Maria Konnikova sets us straight in her new book, The Confidence Game: Why We Fall for It…Every Time....

Lift A Large Load Using Liquids

Key Concepts Physics Engineering Simple Machines Force Pressure Introduction Not even the strongest human could lift a truck into the air. Our brains, however, are smart enough to create a tool that can lift heavy objects for us: hydraulic lifts! You can find them at car repair shops, in wheelchair lifts, and even on skyscraper construction sites. They use water (or other liquids) to increase the force available to lift things....

Meat Of The Matter Are Our Modern Methods Of Preserving And Cooking Meat Healthy

John Durant really likes meat, but he does not keep much of it in his refrigerator—there is not enough room. Instead he stores his meat in a large white freezer chest in his shared Manhattan apartment. Durant, 29, opens the chest and pulls out some frozen chunks of venison wrapped in butcher paper. He digs through the ice to find a couple of cuts of grass-fed beef. He shows me lamb kidneys, pork fatback and ham hocks....

Nations Squabble Over Room In The Atmosphere For Pollution

WARSAW – One question, now that the world’s climate scientists have definitively declared that humanity has triggered global warming, is what to do with the United Nations agency established to assess the robustness of climate science? A group of 130 developing countries, headed by Brazil, has an answer: Instruct the Intergovernmental Panel on Climate Change to investigate historic emissions. In their thinking, apportionment of past emissions would bring clarity to just who’s responsible for fixing the mess that’s brought the world to the brink of climate chaos....

Out To Launch Mystery Missile Off California Coast Was Probably Just An Airliner Pentagon Says

When the crew of a KCBS television news helicopter caught sight of a growing, glowing streak in the evening sky off the southern California coast November 8, experts and amateurs alike began to wonder just what this “mystery missile” was. To the dismay of conspiracy theorists everywhere, the sky trail seems to have been caused by an ordinary passenger plane, according to the Pentagon and some independent experts. “It’s clearly an airplane contrail,” says John Pike, director of GlobalSecurity....

Proteins Behind Mad Cow Disease Also Help Brain Develop

Prions are best known as the infectious agents that cause ‘mad cow’ disease and the human versions of it, such as variant Creutzfeldt–Jakob Disease. But the proteins also have at least one known useful function, in the cells that insulate nerves, and are suspected to have more. Now researchers have provided the first direct evidence that the proteins play an important role in neurons themselves. The team reports in the Journal of Neuroscience that prions are involved in developmental plasticity, the process by which the structure and function of neurons in the growing brain is shaped by experience....

Secrets Of Successful Parenting

The findings might surprise you. Academic testing, for instance, has a terrible rap these days. Yet done correctly, it beats other study methods for fixing information in a student’s mind. Moreover, telling children that they are smart can backfire; if you want them to be eager learners and creative thinkers, praising effort is far more effective. Beyond wanting our children to love learning, we hope that they will get along well with others, be happy and bounce back from adversity....

Sewer Studies Based On Leaky Science

By Hannah HoagChemicals flushing into sewer systems have been in the news for years. From opiates and hormones to heart medications, studies have detected a range of pollutants. Tests of sewage from hospitals have uncovered antibiotics, and investigations of sewage systems have exposed widespread illicit drug use in cities worldwide.But now a group of water-management scientists claim that some of these studies may be making exaggerated claims, producing dramatic variation in concentration estimates or not detecting substances because of fundamental flaws in sampling protocols....

Should Prisoners Be Used In Medical Experiments

The year was 1946, and under the guise of public health hundreds of Guatemalan prison inmates were deliberately infected with syphilis. Male prisoners were sometimes infected via direct injection—including right to the penis. Still other prisoners got sick after visits from prostitutes who were often also purposely infected. None of the research subjects were asked for their consent. Some six decades later Pres. Barack Obama called Álvaro Colom, Guatemala’s president, to personally apologize for the abhorrent U....
