Study concludes there is no such thing as ‘gay gene’

Technology
There is no such thing as a "gay gene" - but there is a mix of genetic and environmental factors which influence sexual behaviour, scientists have said.Researchers examined the genetics of almost half a million people who self-reported on whether they had experienced same-sex sexual behaviour - defined in the study as having ever had sex with someone of the same sex. They could not find any patterns among genetic variants that could be used to meaningfully predict or identify a person's sexual orientation or behaviour.Their findings indicate that like personality and other complex human traits, the behaviour is influenced by a combination of genetic and environmental factors.The authors analysed survey responses and performed genome-wide association studies (GWAS) on data from more than 47...
Roach-inspired robot nearly as fast as real thing, unsquashable

Roach-inspired robot nearly as fast as real thing, unsquashable

Science
July 31 (UPI) -- If you see the latest robot from the University of California, Berkeley scurrying across your kitchen floor, don't bother trying to step on it. The novel roach-like robot, described this week in the journal Science Robotics, can't be squashed. The new robot, developed by engineers at Cal, can run nearly as fast as a cockroach and as is even harder to kill. If one were to stomp on the little robot, the durable electronic bug would likely emerge unharmed. "Most of the robots at this particular small scale are very fragile. If you step on them, you pretty much destroy the robot," Liwei Lin, a professor of mechanical engineering at Berkeley, said in a news release. "We found that if we put weight on our robot, it still more or less functions." It's small stature, speed and d...
Here's why getting exactly zero back from the IRS might be a good thing

Here's why getting exactly zero back from the IRS might be a good thing

Forget about that gigantic refund: What you really want from the IRS is a tax balance of exactly zero and no big check. That's because hitting zero with the taxman — that is, neither owing a balance nor receiving a refund — is an indication that you paid exactly the amount of tax liability you owed. A select group of taxpayers managed to hit that goal during the 2016 tax year, according to SmartAsset's analysis of IRS data. Montana happens to be home to the greatest number of filers who owed nothing and received nothing in return from the ...

Former North Dakota Democratic Sen. Heidi Heitkamp's path to the Capitol wasn't paved in gold. In fact, Heitkamp said growing up in rural North Dakota, her family faced many financial challenges. "We talked about money all the time and how there wasn't enough of it," she told CNBC. She said the first thing she ever paid for on her own was probably a school lunch. "We shared that family responsibility for a budget." She credits the lessons she learned early on for the fina...
