A new species of titanosaurian, a member of the large-bodied sauropods that thrived during the final period of the dinosaur age, has been found in Tanzania.

Many fossils of titanosaurians have been discovered around the globe, notably in South America, but few have been recovered from the continent of Africa. 

A new study has found that the pond-dwelling, single-celled organism Oxytricha trifallax has the remarkable ability to break its own DNA into nearly a quarter-million pieces and will then rapidly reassemble those pieces when it's time to mate.

Why? No one knows, sometimes nature gets drunk and creates things that make no sense. The organism internally stores its genome as thousands of scrambled, encrypted gene pieces. Upon mating with another of its kind, the organism rummages through these jumbled genes and DNA segments to piece together more than 225,000 tiny strands of DNA. This all happens in about 60 hours.

Immunotoxins are targeted antibodies that go after deadly toxins like ricin.

In the quest to find targeted therapies for cancer - that kill cancer but spare the surrounding tissue, immunotoxins make perfect sense. But they have not succeeded in part because cancer cells share many molecules with normal cells and because it can be challenging to unlock the deadly chemical only after the antibody has homed to the diseased tissue.

At first glance, water seems to be a simple molecule because a single oxygen atom is bound to two hydrogen atoms - but it is more complex when taking into account hydrogen's nuclear spin, a property reminiscent of a rotation of its nucleus about its own axis. 

The spin of a single hydrogen can assume two different orientations, symbolized as up and down. So, the spins of water's two hydrogen atoms can either add up, called ortho water, or cancel out, called para water. Ortho and para states are also said to be symmetric and antisymmetric, respectively.

In 2014, there will be an estimated 22,240 new cases of ovarian cancer in the United States and over 40,000 new cases in the European Union. Ovarian cancer is one of the most lethal gynecologic cancers. Women with recurrent or persistent ovarian cancer recur within 6-12 months of completion with a platinum-containing regimen and there remains a high unmet need for improved treatment options.
