Google has now started blocking websites that use deceptive content or ads to make you do things that you wouldn't normally do, such as fake download buttons that appear right next to the real download button, or pop-ups demanding you phone tech support to remove a million malware infections that were apparently found on your computer. It sounds like this will be a gradual rollout; it'll take time for Google to work out which sites are consistent offenders.

The blocking will occur via Google's Safe Browsing tech, which you've probably seen before: it's that big red interstitial that appears when you click on a dodgy search result. Safe Browsing has been around for years, but it mostly just prevented you from visiting sites that were serving up malware, or sites that Google had otherwise deemed unsafe.

In November, however, Google started blocking sites that used "social engineering attacks" to get you to install unwanted software or reveal sensitive information—and today, Google is expanding that to websites that serve up deceptive embedded content (i.e. adverts). Google gives the following examples of ads that will get a website blocked:

LIVINGSTON, La.—The rain began to fall as Joe Giaime and I scrambled down a lonely rise, back toward the observatory’s main building. It wasn’t so much rain as a hard mist, characteristic of the muggy weather southern Louisiana often sees in January when moisture rolls inland from the Gulf of Mexico. As gray clouds fell like a shroud over the loblolly pines all around us, Giaime mused, “Well, I guess you’ve already gathered that we’re in the middle of nowhere."

Middle of nowhere happens to be ground zero in the search for gravitational waves, which were first posited by Albert Einstein a century ago and may soon become one of the hottest fields in science. Livingston is remote in terms of geography, but as humans scan the heavens for gravitational waves this forest is practically the center of the physics universe.

Because of general relativity, we understand that large masses curve spacetime, kind of like standing in the middle of a trampoline distorts the fabric. When massive, dense objects in space accelerate, such as black holes or neutron stars, they create ripples in the fabric of spacetime. These ripples carry gravitational radiation away from the very massive objects, and the radiation then propagates through the Universe. This Louisiana observatory, the Laser Interferometer Gravitational-Wave Observatory or LIGO, exists to try to measure these subtle ripples.
