How madagascar’s lizards became the island’s last hope for reforestation

After the island of Madagascar drifted away from India 88 million years ago, isolating it from all other landmasses, its flora and fauna evolved in seclusion. As these transformed into plants and animals completely unique to their island, Madagascar became a biodiversity hotspot unlike anywhere else on Earth. An important facet of this biodiversity is […]

What a dinosaur ate 100 million years ago—Preserved in a fossilized time capsule

Plant fossils found in the abdomen of a sauropod support the long-standing hypothesis that these dinosaurs were herbivores, finds a study published on June 9 in the Cell Press journal Current Biology. The dinosaur, which was alive an estimated 94 to 101 million years ago, ate a variety of plants and relied almost entirely on […]

Take Care When Paying Volume-Based Compensation to Sales Agents to Avoid Anti-Kickback Statute Violations – Duane Morris Life Sciences Law

By  Frederick R. Ball, Coleen W. Hill and Victoria (Tori) Hawekotte Pharmaceutical companies sometimes compensate sales agents per volume sold. The Fifth and Seventh Circuits have indicated that a company may structure such arrangements without running afoul of the Anti-Kickback Statute (AKS). However, such arrangements carry risk of violating the AKS and should […]

Satellite tracking of 12,000 marine animals reveals ocean giants are in trouble

A sweeping new study is helping pinpoint where whales, sharks, turtles, and other ocean giants need the most protection and where current efforts fall short. Led by Ana Sequeira of Australian National University and supported by the United Nations, the research synthesized data from 12,000 satellite-tracked animals across more than 100 species. It reveals how […]

Extreme weather is wiping out amphibians—Here’s where it’s worst

The fire salamander native to Europe is one of many species that depend on sufficient moisture. Credit: Daniel Rosengren/Frankfurt Zoological Society Habitat loss, diseases, pollution, and climate change are already massively affecting amphibians – frogs, salamanders, and the caecilians native to tropical regions. The new study from the Institute for Ecology, Evolution and Diversity shows […]

Two plant species invent the same chemically complex and medically interesting substance

The elucidation of the biosynthetic pathway of ipecacuanha alkaloids shows how two distantly related plant species could develop the same substance independently. Plants produce an enormous abundance of natural products. Many plant natural products are ancestry-specific and occur only in certain plant families, sometimes only in a single species. Interestingly, however, the same substances can […]

Eating an array of smaller fish could be nutrient-dense solution to overfishing

To satisfy the seafood needs of billions of people, offering them access to a more biodiverse array of fish creates opportunities to mix-and-match species to obtain better nutrition from smaller portions of fish. The right combination of certain species can provide up to 60% more nutrients than if someone ate the same quantity of even […]

Student discovers long-awaited mystery fungus sought by LSD’s inventor

Making a discovery with the potential for innovative applications in pharmaceutical development, a West Virginia University microbiology student has found a long sought-after fungus that produces effects similar to the semisynthetic drug LSD, which is used to treat conditions like depression, post-traumatic stress disorder and addiction. Corinne Hazel, of Delaware, Ohio, an environmental microbiology major […]

Mammals didn’t walk upright until late—here’s what fossils reveal

For over a century, scientists have puzzled over a fundamental mystery in our evolutionary history: how did mammals go from sprawling like lizards to striding like cats and dogs? This transition — from a sprawled stance (like a lizard) to an upright (parasagittal) posture — marked a pivotal moment in mammal evolution. While the earliest […]

A coordinated kinase and phosphatase network regulates Stu2 recruitment to yeast kinetochores

Cells coordinate diverse events at anaphase onset, including separase activation, cohesin cleavage, chromosome separation, and spindle reorganization. Regulation of the XMAP215 family member and microtubule polymerase, Stu2, at the metaphase-anaphase transition determines a redistribution from kinetochores to spindle microtubules. We show that cells modulate Stu2 kinetochore-microtubule localization by Polo-like kinase1/Cdc5-mediated phosphorylation of T866, near the […]
