US Drought Isn't Going Anywhere Anytime Soon
According to recent figures, a full 61 percent of the country is experiencing drought conditions, almost double the amount in 2011. Some are warning of a coming "megadrought" in the western US.
What's the Latest Development?
Drought conditions in the US are worsening to the point where research meteorologist Martin Hoerling compares it to "the blob in the old Steve McQueen movie." Sixty-one percent of the country is experiencing drought, and that number climbs to 79 percent when including areas that are seen as being "abnormally dry." Although recent storms have brought a measure of relief, experts say that the "blob" will expand deeper into northern and eastern states through the end of October.
What's the Big Idea?
The continent has experienced drought conditions before, so this particular drought can't entirely be blamed on human-created climate change. However, across the planet, subtropical areas are drying out, and the drying is slowly spreading north and south, which is consistent with existing climate change models. A drought that affected the western US earlier this century fit the pattern, and was the worst seen in that region in 800 years. However, given current projections, researcher Christopher Williams says that what's coming "could make that drought look positively moist."

"I was so moved when I saw the cells stir," said 90-year-old study co-author Akira Iritani. "I'd been hoping for this for 20 years."
- The team managed to stimulate nucleus-like structures to perform some biological processes, but not cell division.
- Unless better technology and DNA samples emerge in the future, it's unlikely that scientists will be able to clone a woolly mammoth.
- Still, studying the DNA of woolly mammoths provides valuable insights into the genetic adaptations that allowed them to survive in unique environments.
An MIT study predicts when artificial intelligence will take over for humans in different occupations.
While technology develops at exponential speed, transforming how we go about our everyday tasks and extending our lives, it also offers much to worry about. In particular, many top minds think that automation will cost humans their employment, with up to 47% of all jobs gone in the next 25 years. And chances are, this number could be even higher and the massive job loss will come earlier.
The blood of horseshoe crabs is harvested on a massive scale in order to retrieve a cell critical to medical research. However, recent innovations might make this practice obsolete.
- Horseshoe crabs' blue blood is so valuable that a quart of it can be sold for $15,000.
- This is because it contains a molecule that is crucial to the medical research community.
- Today, however, new innovations have resulted in a synthetic substitute that may end the practice of farming horseshoe crabs for their blood.
