Most of California's Big Earthquakes Are Preceded by Ghostly 'Foreshocks' Weeks in Advance

How do earthquakes begin? It's an ancient question — and while scientists have ruled out the vengeful gods blamed over the past few millennia, agreeing that tremors are more a matter of grinding plate tectonics than of Poseidon's wrath, many facets of this seismic puzzle remain murky.  One ongoing mystery is the phenomenon of foreshocks, small, sometimes imperceptible tremors that can precede larger quakes in the same area by several days or weeks.

Photos: Kangaroos Use Tails to Walk

Kangaroo newsKangaroos walk using all four limbs and their tails more often than they hop on their hind legs, and new research published July 1, 2014 in the journal Biology Letters finds that their tails actually act as a fifth leg. Here, an illustration of the kangaroo's fore limb, hind limb and tail bones.

Plate Tectonics Becoming Clearer With Computers

Computers may now be better than ever at revealing how the giant plates of rock that we live on will drift, crash and dive against each other to shape Earth throughout its history, scientists say. The findings of a new study on a plate tectonics model could help better understand the factors driving earthquakes, the formation of mountains and the rifting of continents, the researchers said. Computer models that simulate the motions of the tectonic plates that make up Earth's crust are continually becoming more powerful. [Read More]

Size Matters to Spiders: Smaller Males Have Advantages

Male spiders can be tens of times smaller and weigh one hundredth of what their female counterparts weigh, and new research shows that these size differences may be in part due to a spider behavior called bridging. Bridging is a means of transportation for spiders living in the trees and other vegetation of forests and meadows. In bridging, a spider casts a strand of its silk into the wind, and the silk is carried aloft to a neighboring plant. [Read More]

Smart Shades: High-Tech Windows Can Turn Dark in Just 1 Minute

The smart windows, developed by engineers at Stanford University and described in a study published online Aug. 9 in the journal Joule, rely on a completely different principle compared to existing alternatives known as dynamic windows. The new approach uses a polymer gel containing metal ions applied on top of a transparent electrode. When voltage is applied, the metal ions plate the electrodes, blocking all wavelengths of light. After the opposite voltage is applied, the windows switch back to being transparent. [Read More]

Texas Mayor Said Killed by Rare Donkey Attack

The mayor of a South Texas town appears to have been attacked and killed by a 500-pound donkey, according to the Associated Press. The body of William “Bill” Bohlke, the 65-year-old mayor of Hollywood Park, was found on Monday night (Aug. 27) by sheriffs and relatives who went looking for him after he failed to return home from tending to his cattle ranch. Atascosa County Chief Deputy David Soward told the San Antonio Express-News the search party’s findings on the ranch made it clear a combative male donkey had been responsible for the mayor's death.

The Faults That Ruptured in Twin California Quakes Are Very, Very Weird, Geologists Say.

On July Fourth, the most powerful earthquake to hit Southern California in nearly 20 years struck a remote part of the Mojave Desert. A day later, an even larger temblor rocked the same area. Though earthquakes beget earthquakes, there's generally thought to be just a 5% chance that one quake will be followed by an even more powerful one, according to geoscientists. But that wasn't the only unusual feature of this earthquake duo in SoCal. [Read More]

The mysterious connection between the coronavirus and the heart

The novel coronavirus(opens in new tab) mainly attacks the lungs. But doctors have been increasingly reporting cases of another battlefield raging within the body: the heart. More than 1 in 5 patients develop heart damage as a result of COVID-19 in Wuhan, China, one small study published March 27 in the journal JAMA Cardiology suggested. While some of these patients have a history of heart conditions, others do not. So what's going on? [Read More]

What's Behind Toddler's Extremely Rare Water Allergy?

We can't live without water, but for one toddler in Minnesota, contact with plain old H2O can be dangerous — she has an extremely rare allergy that causes her to break out in hives and rashes anytime she touches water, according to news reports. The 18-month-old, Ivy Angerman, was recently diagnosed with aquagenic urticaria, or an allergy to water, according to local news station Fox 9. Her doctors say she may be the youngest person ever diagnosed with the condition, which more often appears around the age of puberty. [Read More]
