Source: Original cartoon by Alex Martin Without modern medical science, a baby’s sex would remain unknown until birth. But many mothers today know long beforehand whether a baby will be male or female. Routine ultrasound scans reveal fetal genitals a third of the way through pregnancy, and genetic tests identify sex even earlier. Yet basic questions remain. Is a baby’s sex like coin tossing, or can the male:female ratio be skewed? If sex bias occurs, does it happen through sperm sorting before fertilization or mortality differences in the womb after conception?

What if, rather than pay estate agents to find a single buyer, you simply sold raffle tickets for your home? Back in 2017 that was the exact plan used by Dunstan Low - owner of the six-bedroom Melling Manor near Kirkby Lonsdale. His "Win a country home" competition sold 450,000 tickets at £2 each and resulted in officer worker Marie Seager walking away with the property a few months later - which she's now rented out. Since that initial success, dozens of homes have gone up for sale this way - but almost none of them have resulted in a home changing hands. Some of the competitions have refunded cash, others have simply vanished while most have seen the "winner" walk away with a cash prize instead of a home. Then there are the competitions that won't die - with owners simply extending the "draw" date again and again in an effort to drum up enough ticket sales to make the whole process worthwhile. Marc Gershon, of recent raffle operator Win my Dream Home , said: “When you … [Read more...] about Does anyone ever win? A look inside the remarkably murky world of house raffles
Adolescence is that time between the start of puberty and the acceptance of adult roles in society. In the developed world, this period of life usually ranges from around 13 to the early twenties. It’s a time when young people begin asserting their independence and forming their first deep attachments outside the family. And for many adolescents, it’s also a time for taking risks and exploring new experiences. Many people blame raging hormones for teenagers’ reckless behavior, and no doubt that’s one reason. Testosterone, the hormone of sex drive, aggression, and risk-taking behavior, surges in the years after puberty. But not all teens drive fast, do crazy stunts on their roller blades, try out drugs, or engage in risky sex. So there must be other explanations. Some scholars argue that adolescence is a manufactured phenomenon of Western society, a by-product of keeping our children dependent far longer than is natural or necessary. Because of the lengthy … [Read more...] about Why Your Teenager Does Such Crazy Things
Bengaluru, September 12: The national selectors will meet on Thursday (September 12) to pick the Test squad for three-match India vs South Africa Test series beginning at Visakhapatnam on October 2. While most the of the squad members pick themselves, there could be doubt over opener KL Rahul. Here's MyKhel looks at the possible squad. 1. KL Rahul may get the axe Rahul has been going through a modest patch as reflected in his two fifty-plus scores in the last 27 innings. His last 50-plus score was the 149 against England at the Oval in 2018. Since then, he has made several starts and promised better and bigger innings. But it never happened and the latest example was the first Test against the West Indies at Antigua when made 38 and 44. 2. Who are in contention for opener's slot Despite a lean outing against the West Indies, Mayank Agarwal, who made his Test debut against Australia earlier this year, is certain to get another chance. If the selectors indeed drop Rahul, then they … [Read more...] about India vs South Africa 2019: Test team selection: Rahul may get axe, focus on Easwaran, Gill
There is a very good chance that if you suffer from depression, you may have a coexisting problem like an anxiety disorder. In our research of individuals with depression, 75% of them had a coexisting anxiety disorder. This makes sense in that both depression and anxiety have a relationship to your sense of focus on time. For example, in depression, you are probably focused on a loss (e.g., a relationship, position, money) that has already occurred. In anxiety disorders, you are focused on an upcoming loss that you anticipate occurring. Time Focus Source: Wikimedia Commons This relationship to time focus highlights one of the ways that MBCT (Mindfulness-Based Cognitive Therapy) helps: it brings your focus to the present moment, letting go of looking at the past or the future. If you are focused on your breath in this moment, you cannot be focused on past losses or future catastrophes. The focus on the present represents one of MBCT’s transdiagnostic features. This term, … [Read more...] about Does MBCT Help Other Problems Besides Depression?
If you’re like me, chances are good you just distractedly clicked on this article while scrolling through your feed in, or while waiting for, a Lyft. Maybe, like me, you need that app to get to back-to-back meetings in different locations today, as you’re well on your way to at least a 60-hour workweek between the various things you do. Maybe you’re exhausted. Maybe the ride you just took, zoning out on your phone in an Uber on Quiet Mode, was actually a lifesaver. And as you settle into each new driver’s backseat, en route to each new destination in your crazy busy life, maybe, like me, you find yourself somewhat unwittingly implicated in one of the most contentious ethical struggles of this generation – a struggle with profound implications for the future of work. Yesterday, California-based advocacy organizations Gig Workers Rising and Mobile Workers Alliance announced that a caravan of Uber and Lyft drivers will drive from SoCal through San Francisco … [Read more...] about Hundreds of Uber and Lyft drivers to launch a protest caravan across California
