In the blink of a few thousand likes and shares, Texas teacher Brandy Young's homework policy gained the viral notoriety normally reserved for tip-shaming.

Earlier this month, Young informed parents of her Godley Elementary second-graders of her policy for the year: no homework.

ROBERT SIEGEL, HOST:

Bernie Sanders is launching a new political organization. It's called Our Revolution. It aims to support candidates and, according to its website, "advance the progressive agenda that we believe in."

But the revolution is getting off to a rocky start.

Eight key staffers abruptly resigned over the weekend in a dispute over the group's leadership and legal structure.

Sanders himself is set to address followers on Wednesday at 8 p.m. ET for the launch of the group. You can watch that here:

For such a commonplace bodily function, the sneeze has messed with our minds (and noses) for centuries. It will kill us, it won't kill us. We'll have bad luck, we'll have good luck. Watch out for Satan, he's wily and knows how to get into your nasal membranes. Did you have too much to eat? Are you sad? Do you have a weak heart?

To a mathematician, it's a violent explosion that shoots out missiles of hot, wet air, slamming a turbulent cloud of moisture into anybody or anything that crosses its path.

To the rest of us, it's a sneeze.

The Bombay to Barcelona Library Cafe sits on one side of a noisy street in a lower-middle-class neighborhood of Mumbai, India, not far from the city's swanky new international airport.

Like a lot of people's grandmothers, Flonzie Brown-Wright keeps a candy jar in the living room of her single-story home, which is also adorned with potted plants and family photos.

They call it the octobot.

The squishy eight-legged robot described in the journal Nature is made entirely out of soft, flexible materials, runs on hydrogen peroxide, and looks like a 2-centimeter-tall baby octopus.

A major study about the best way to treat early-stage breast cancer reveals that "precision medicine" doesn't provide unambiguous answers about how to choose the best therapy.

"Precision doesn't mean certainty," says David Hunter, a professor of cancer prevention at Harvard's T.H. Chan School of Public Health.

That point is illustrated in a large study published Wednesday in the New England Journal of Medicine, involving decisions about chemotherapy.

EpiPens are in your friend's purse and your kid's backpack. The school nurse has a few, as does Grandma.

The medicine inside — epinephrine — has been around forever, and the handy gadget that injects it into your leg is not particularly new either.

So members of Congress, responding to their angry constituents, want to know why the price of the EpiPen, which can reverse a life-threatening allergic reaction, has risen about fivefold in the past decade.

Newborn conjoined twins were evacuated from a Syrian rebel stronghold to the capital Damascus after lengthy negotiations earlier this month.

But brothers Moaz and Nawras died early Wednesday before they could be transferred to a hospital outside Syria for urgent heart surgery. It's a tragic end to a story that was the subject of an international campaign to save their lives.

Canada's national police force says it is allowing women in its ranks to wear the hijab.

A spokesman confirmed Wednesday that the Royal Canadian Mounted Police, known as the Mounties, recently approved the headscarf for its Muslim officers.

Tropical Storm Colin ripped across the Gulf of Mexico in June and hit the coast of southwest Florida with 60-mile-an-hour winds. Before it arrived, a team from the U.S. Geological Survey used a new computer model to predict how far inland the waves would invade. When the storm hit, the USGS sent Joe Long out to film it.
