Plenty of toys on the market promise to provide the next generation of coders and engineers with the foundation they'll need to compete in the rapidly-changing job market. But in a sea of coding-for-kids products, an update to Anki's holiday-shopping darling, Cozmo the robot, offers a chance for young would-be coders to tap into a complex machine capable of advanced feats, like facial recognition.
The ultimate goal of a lumpectomy is to remove all the cancerous tissue from a person's breast while saving as much of the healthy tissue as possible. But that's even harder than it sounds. Without the ability to look at tissue under a microscope, it's currently impossible to tell whether the area surrounding a tumor contains cancerous cells or not. Surgeons deal with this by taking samples from around the removed tumor, waiting for a pathologist to look at them, and performing additional surgeries if they turn out to be cancerous. This is not only time consuming and expensive, but also extremely stressful for the patient.
Pandas get a lot of attention—and given how hard it is to keep those black and white bundles of fluff from going extinct, it's not surprising that they take up a huge glut of the world's conservation funding. These are animals that literally evolved to be lazy: the only food they eat, bamboo, is incredibly hard for them to digest, so they have to consume about 30 pounds of it a day (around a fifth of that is actually digested) and expend so little energy that they basically live in a state of suspended animation. They also seem to suffer from pretty constant gastrointestinal disorders, and they're notoriously difficult to breed in captivity. Still, we work to save them. In fact, thanks to aggressive conservation efforts from China, the animals moved from "endangered" to "vulnerable" status in 2016.
The biological differences between men and women can affect the way they react to certain drugs and treatments, according to a new study in Nature Communications. If this sounds like a no brainer, you probably haven't looked at many biomedical studies. As PopSci noted earlier this year, biomedical researchers experiment almost exclusively on male animal subjects. A 2011 study found that animals in medical research are up to five times more likely to be male than female.
On May 22, 1960, the largest earthquake ever measured struck off the coast of southern Chile. Once the shaking stopped, Denis García, a resident of the nearby port town Corral, noticed something odd. He was searching for his family, not realizing they were safe and on high ground, when he caught sight of Corral Bay. The waters had drawn back, leaving the seafloor bare. García went to investigate. He did not see the 40-foot-high tsunami barreling toward him until it was too late.

We all know what an egg looks like, right? Well, we might know less than we think—bird eggs can be spheres, teardrops, oblong, and anything in between. An interdisciplinary group of scientists may have made progress in cracking the mystery behind how these different shapes emerged.
Ticks are horrifying, plain and simple. Even if they weren't vectors for nasty infections, the fact that they swell up like tiny blood balloons and then burst if you don't remove them properly is enough to make you never want to set foot in the woods again. And guess what: they can also make you allergic to hot dogs and hamburgers, which is pretty darn unpatriotic for a tick named Amblyomma americanum.
"Are you allergic to any medications?" I've answered that query dozens of times since a childhood incident when penicillin, taken to treat a minor infection, instead gave me an itchy rash all over my body. So I respond automatically, and call out the common antibiotic. But I recently learned that this diagnosis could be wrong. Penicillin sensitivity can disappear over time, a fact researchers have known for years. So why hasn't my doctor told me to go get an official test? It could be because she doesn't actually know the allergy can fade.
