An antibody is an agent of the immune system that attaches to an antigen. Usually antibodies recognize antigens on a virus or bacteria and attach to the invader to mark it for destruction by other immune cells.

In a new study,  University of Colorado Anschutz researchers engineered an antibody to recognize and attach to a protein called EGFR. Bladder tumors (but not healthy cells) are often covered in EGFR. Other researchers have hooked molecules of chemotherapy to antibodies that recognize EGFR and have used this antibody-antigen system to micro-target the delivery of chemotherapy. In this case, researchers used nifty chemistry to attach gold nanoparticles to antibodies.
This well-preserved partial ichthyosaur was found in the Blue Lias shales by Lewis Winchester-Ellis. The vertebrae you see are from the tail section of this marine reptile. The find includes stomach contents which tell us a little about how this particular fellow liked to dine. As with most of his brethren, he enjoyed fish and cephalopods. Lewis found fish bone and squid tentacle hooklets in his belly. Oh yes, these ancient cephies had grasping hooklets on their tentacles. I'm picturing them wiggling all ominously.

This fellow is Chengjiangocaris kunmingensis, a rather glorious fuxinhuiid arthropod. While he looks like he could be from the inside of the Lascaux Caves and their fire-kissed Palaeolithic paintings, albeit by a very ancient Picasso, he was found at a UNESCO World Heritage Cambrian fossil site in southern China.

As his name indicates, he is from a locality in the Yunnan region near Kunming. He is unusual in many ways, both because of the remarkable level of preservation and the position in which he was found.
Meet one of the most adorable of all the Living Fossil species, the Elephant shrew, Macroscelides proboscideus, one of 15 species of this order. These small, quadrupedal, insectivorous mammals strongly resemble rodents or opossums with their scaly tails, elongated snouts, and rather longish legs. 

Move over Burgess, there's a new Cambrian Lagerstätten in town. Meet Tuzoia sinesis from the Balang Formation of southern China. 
Salmon have permeated First Nations mythology and have been prized as an important food source for thousands of years. 

For the Salish people of the Interior of British Columbia, Canada, salmon was the most important of the local fishing stock and salmon fishing season was a significant social event which warranted the nomination of a “Salmon Chief” who directed the construction of the hooks, weirs and traps and the distribution of the catch.

Plesiosaurus were large, carnivorous air-breathing marine reptiles with strong jaws and sharp teeth that moved through the water with four flippers. We'd originally thought that this might not be the most aerodynamic design but it was clearly effective as they used the extra set to create a wee vortex that aided in their propulsion. In terms of mechanical design, they have a little something in common with dragonflies.

From the Trump administration’s Muslim travel ban to its family separation policy, many Americans object to the White House’s hardline immigration policies as a historical aberration out of sync with U.S. values.

Having explored the evolution of these policies and their consequences as both a practitioner of immigration law and scholar of U.S.-Latin American relations, I disagree.

In April 2017, journalists promoted a claim about plastic bag eating caterpillars which led to sensationalistic coverage in worldwide media. They could eat the sea-sized floating islands of plastic bags that don't actually exist.

The science community was skeptical. 
Sometimes pop culture becomes fact for the public. When the climate disaster film "The Day After Tomorrow" came out, journalists bizarrely started referencing it as a real climate change scenario, and now that Netflix, the home of anti-science sentiment among streaming services(1), has "Chernobyl" available, people think that is creating mutants.(2)
