We Are Built To Be Kind

Greed is good. War is inevitable. Cooperation is for suckers. 

Whether in political theory or popular culture, human nature is often portrayed as selfish and power hungry. UC Berkeley psychologist Dacher Keltner challenges this notion of human nature and seeks to better understand why we evolved pro-social emotions like empathy, compassion and gratitude.

Maple syrup could help fight bacterial infections, Canadian scientists find

Maple syrup is once again making headlines for being the rockstar condiment that every Canadian knows it is, but it’s not the culinary world that’s buzzing this time — it’s the medical world. Newly released research from McGill University in Montreal suggests that concentrated maple syrup extract may actually help fight bacterial infections, potentially reducing the need for antibiotics around the world. “Combining maple syrup extract with common antibiotics could increase the microbes’ susceptibility, leading to lower antibiotic usage,” reads a press release issued by the university Friday. “Overuse of antibiotics fuels the emergence of drug-resistant bacteria, which has become a major public-health concern worldwide.”

The Oldest Ancestor of Modern Birds Has Been Found in China

Ever since the birdlike dinosaur Archaeopteryx was first discovered in 1861, paleontologists have tried to decipher the evolutionary origins of modern birds—the only surviving descendants of the dinosaurs.

Now, paleontologists based out of the Chinese Academy of Sciences (CAS) have reached a new milestone in this quest. The CAS team has discovered the oldest fossils from the Ornithuromorpha group of dinosaurs, the common ancestor of all modern bird species.

The two specimens date back 130 million years to the Early Cretaceous period, when pterosaurs still dominated the skies. They belong to a new species named Archaeornithura meemannae, a feathered wading bird that lived in what is now northeastern China. The CAS team, led by paleontologist Min Wang, published a detailed analysis of the new specimens today in Nature Communications.

Bobbit Worm. By: ken & anita’s photos

The Bobbit worm, Eunice aphroditois, is a ferocious underwater predator. Armed with sharp teeth, it is known to attack with such speeds that its prey is sometimes sliced in half. Though they do vary in size, they have been recorded to grow up to nine feet tall.

Flower Mushroom Coral - Ricordea yuma

Ricordea yuma (Corallimorpharia - Ricordeidae) is a species of soft coral belonging to a group commonly referred to as mushroom corals. These soft corals are very popular among aquarists due to their vibrant and varied color patterns. 

Ricordea yuma is found in the tropical Pacific. Like other Corallimopharians, this one has the ability to rapidly colonize available substrate.

KISS OF DEATH

One of the reasons cancer is so hard to defeat is that the body’s immune system has trouble recognizing cancer cells growing among healthy cells. Some scientists want to help. Researchers designed mouse T cells to specifically bind to a protein complex on fibrosarcoma MC57 tumor cell membranes. In this sped-up video, once the T cells (each about 10 μm across) meet their targets, they create holes in the cancer cell membranes using a protein called perforin. Next, the immune cells flood the pierced cells with a rush of cell-killing granules called granzymes. Propidium iodide, a dye the scientists added to the plate of cells, also squeezes in through the hole and starts glowing red when it comes in contact with RNA and DNA inside the cancer cells. This tells the researchers that the cells have been pierced and will soon die. This process takes about 75 minutes in real time.
