New study puts a number on what 'Exxon knew' decades ago about climate science

Climate projections reported by ExxonMobil scientists between 1977 and 2003 were accurate and skillful in predicting subsequent global warming and contradicted the company's public claims, a new Harvard study shows.

How did the Butterfly Nebula get its wings? It's complicated

Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel—becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, ...

Study clarifies mystery of crocodilian hemoglobin

It can pogo-stick along at 50-plus miles per hour, leaping 30-odd feet in a single bound. But that platinum-medal athleticism falls by the wayside at a sub-Saharan riverside, the source of life and death for the skittish ...

Ancient ostrich eggs found in southern Israeli desert

Climate goals achievable at affordable cost: Study

Climate change could be constrained by implementation of policies to ensure fossil fuel producers pay for carbon clear-up, or capture, according to new Oxford-led research, published today in Environmental Research Letters.

Scientists take another step toward creating better pain medications

In the continuing effort to improve upon opioid pain relievers, American and Chinese scientists used cryoEM technology to solve the detailed structures of the entire family of opioid receptors bound to their naturally occurring ...

How gut bacteria evade the immune system

Researchers from the Max Planck Institute for Biology Tübingen address the long-standing question of how benign gut microbes evade the immune system. In doing so, they also reshape our understanding of how immune receptors ...

Exploring the air we breathe

Melbourne Pollen—a service at the University of Melbourne's School of BioSciences that forecasts the level of grass pollen and several other types of pollen in the air—has been looking at what's in Melbourne's air for ...

Sounding the alarm in time to save endangered species

A few years—or sometimes even just a few weeks—can be all it takes for a plant or animal to acquire "endangered species" status. For instance, when a new road is built through a forest, the chainsaws come out and a rare ...

How immortal jellyfish turn back time

Achieving immortality is something that has driven human beings throughout much of their history. Many peculiar legends and fables have been told about the search for the elixirs of life. Medieval alchemists worked tirelessly ...
