The East Kootenay region on the south-eastern edge of British Columbia is a land of colossal mountains against a clear blue sky.
That is not strictly true, of course, as this area does see its fair share of rain and temperature extremes — but visiting in the summer every view is a postcard of mountainous terrain.
Rocks from deep within the Earth's crust underlie the entire East Kootenay region and are commonly exposed in the areas majestic mountain peaks, craggy rocky cliffs, glaciated river canyons, and in rock cuts along the highways.
I was homeschooled for eight years, from age 11 through to college, before it was a novel way for tiger parents to show off their dynamic commitment to their children’s education. Now, if millions of parents and families are suddenly going to be homeschooling their kids for the coming weeks (and, let’s be honest, quite likely beyond), it’s worth trying to think about how to do this in a manner as smooth, healthy and wise as possible.
Sporting history is littered with tales of defeat snatched from the jaws of victory. Famously, the US golfer Doug Sanders was a three-foot putt away from winning the 1970 Open Championship in St Andrews. He missed. Not only did it lose him the championship, it cost him several sponsorship and endorsement deals too.
Yet belief in medicinal properties remain despite no evidence it does anything. The US Food and Drug Administration (FDA) does say it might help for rare forms of childhood epilepsy, but that has led to charlatans selling it as part of the "wellness" scam.
Supplements are fine for people who are healthy anyway. Yet those who have been duped into being marijuana will help with acne, afib, or anxiety are putting their physical or mental health at risk.
That's not science fiction, and they all belonged to the genus Homo, but only we Homo sapiens have survived. What killed H. habilis, H. ergaster, H. erectus, H. heidelbergensis, and H. neanderthalensis? Nature exists to kill and birth so that seems a more likely culprit than conquest, and a new paper points the blame at one aspect of nature that dominated science media before the coronavirus pandemic - climate change.
Human personality is characterized by a peculiar dualism: it is both stable and malleable, depending on the point of reference. If we compare ourselves to our peers, it is stable as our personality rankings relative to others remain consistent over time. However, personality changes became obvious if we compare ourselves across time, as people become more conscientious, more emotionally stable, and more agreeable as they get older.
In two surveys in the United States, the United Kingdom, and Germany, participants were asked on a scale from 1 to 5 how concerned they are about those who are most vulnerable to SARS-CoV2, the 2019 form of coronavirus that erupted in Wuhan, China and spread worldwide. Subsequently, they were asked about the extent to which they themselves avoid social contact due to the coronavirus. The relationship was clear. The higher the degree of empathy, the greater the focus on reducing social contact.
A new study finds it does not take generations. Tame socialized grey wolves form individualized social bonds with their human handlers. And they don't like being separated any more than dogs do.
Yet the future looks bleak if recent survey results hold true. They find that compared to just a generation ago, college students - and alcohol, like smoking, is most often a pediatric condition - are drinking less alcohol.
Drug development usually starts on a computer, then moves to cells and then animals. Animals, of course, are not little people, despite what anti-science activists like to claim in their war on food and chemicals, so if a drug works in all the preceding steps it will go to human clinical trials where it must survive the real challenge.
For poorer countries, there is good news. Scientists have created a new crystal form of the pyrethroid pesticide deltamethrin that is up to 12 times more effective against mosquitoes. Insecticides such as deltamethrin and DDT can prevent the spread of diseases carried by mosquitoes and are often sprayed indoors and on bed nets. Though DDT, for example, is banned in the United States for political reasons, our EPA writes the book on how to spray it indoors where malaria still exists.
Emmanuelle Charpentier Had To Leave France To Be Allowed To Do The Science For Her CRISPR-Cas9 Nobel
This year’s Nobel prize in chemistry was awarded for a genuine revolution in modern science. The Crispr-Cas9 gene-editing tool allows scientists to precisely alter DNA by cutting and pasting sections of it.
No argument there, anyone would be worried if their surgeon showed up in the operating room without a mask on, but the economists go a little further and claim mask mandates are the reason. They statistically associate mandates with a 25 percent reduction in COVID-19 cases.
The scientific flaws in that logic are well known, but the higher profits and environmental effects are real. Though California has only a tiny amount of organic produce, it requires 300 percent more pesticides to grow the same food as it would if they used regular farming. Organic farmers believe the higher profits are worth the higher economic and environmental costs.
Exponential disks, common in spiral galaxies, dwarf elliptical galaxies and some irregular galaxies, appear smooth and have an exponential fade. How did they get it way?
It's not possible to know but using inference, simulations help provide insight.
