Need To Know
Quake Strikes Colombia
At least 111 people are dead as of this writing after a 7.4-magnitude earthquake struck western Colombia yesterday, leaving dozens more injured and others trapped beneath collapsed buildings (w/photos). Colombia’s strongest earthquake this century was also felt in Ecuador and Panama.
The quake was centered near San José del Palmar in Chocó, a remote region roughly 250 miles west of Colombia's capital, Bogotá (see interactive map). More than 1,500 homes, 50 schools, and 18 health centers were damaged, while over 60 buildings collapsed. Chocó is one of Colombia's poorest regions, with many jungle communities reachable only by boat or plane. The region sits along the Pacific "Ring of Fire," a horseshoe-like belt responsible for 75% of the world's volcanoes and 90% of earthquakes. Explore why earthquakes happen and defy prediction here.
Elsewhere, Tropical Storm Dolphin is expected to bring heavy rain and flooding to eastern China. The storm made landfall as a typhoon Sunday, prompting over 1 million people to evacuate. See photos.
Tupac Trial, 30 Years On
Jury selection began yesterday for the man charged with killing rapper Tupac Shakur. Duane “Keefe D” Davis stands accused of first-degree murder in one of hip-hop's most famous killings. See crime scene photos.
Davis once led the South Side Compton Crips, a rival to the Bloods-affiliated gang associated with Shakur’s record label. On Sept. 7, 1996, Shakur and others were seen assaulting Davis’ nephew after a Mike Tyson fight. Later that night, Shakur was in a black BMW driven by his label’s cofounder when he was fatally shot from a white Cadillac. Prosecutors allege Davis directed the killing but did not pull the trigger and was one of four passengers in the Cadillac (the other three have died). Davis acknowledged his involvement in a 2018 BET interview and 2019 memoir, but pleads not guilty and characterizes the memoir as fiction (free w/email). He previously accused Sean “Diddy” Combs of commissioning the murder, which Combs denies.

Emotional Watchdog
Dogs can differentiate between a range of human emotions by reading our facial expressions, according to brain scan results published yesterday.
Researchers first put eight dogs into MRI scanners (watch how) and showed them photos of people with happy or neutral expressions. The happy faces activated a brain region associated with reward processing, while the neutral faces did not. In a second experiment, 12 dogs were shown photos of people with happy, sad, fearful, and angry expressions. The MRI scans suggest they could distinguish happiness from the three negative emotions, and fear from both sadness and anger. But, for reasons still unclear, the dogs appeared unable to differentiate anger and sadness.
The study authors next want to understand how dogs might process emotions using nonvisual cues, given how heavily they rely on their sense of smell over sight. Dogs can smell about 1,000 to 10,000 times better than humans, and previous research has shown their noses can detect heat.

Others Burn Coal. This Company Cashes It In.
One lump of coal holds six separate commodities, and almost every company on Earth just sets it on fire. Frontieras North America patented a way to split it apart instead.
Their process pulls diesel, jet fuel, naphtha, sulfuric acid, and fertilizer out of the same ton of coal, without burning any of it. One rock. Six markets totaling $2.1 trillion annually*.
Every ton of coal already has a 10-year buyer locked in for the products, so the revenue is contracted before the plant even fully ramps up. Now you can own a piece of the potential growth. Don’t miss your chance to invest before the opportunity closes on 8/27.*
