Hubble watches cosmic light bend

This extraordinary image from the NASA/ESA Hubble Space Telescope of the galaxy cluster Abell 2813 (also known as ACO 2813) has an almost delicate beauty, which also illustrates the remarkable physics at work within it. The ...

Global warming causes uneven changes in heat stress indicators

As the planet warms under the effects of human-caused climate change, prolonged periods of high temperatures are projected to become a significant public health challenge. The elderly are often more susceptible than others ...

Scientists pinpoint our most distant animal relatives

Scientists from Trinity believe they have pinpointed our most distant animal relative in the tree of life and, in doing so, have resolved an ongoing debate. Their work finds strong evidence that sponges—not more complex ...

Breaking the warp barrier for faster-than-light travel

If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport ...

Factoring in gravitomagnetism could do away with dark matter

Observations of galactic rotation curves give one of the strongest lines of evidence pointing towards the existence of dark matter, a non-baryonic form of matter that makes up an estimated 85% of the matter in the observable ...

Tropical paper wasps babysit for neighbors

Wasps provide crucial support to their extended families by babysitting at neighboring nests, according to new research by a team of biologists from the universities of Bristol, Exeter and UCL published today in Nature Ecology ...
