Twice a day, Mars may briefly host water that could support life

What if dark matter came from a mirror universe?

One theory proposes a hidden physical realm with its own versions of particles and forces that gave birth to tiny, stable black hole-like objects that would account for all the dark matter observed today.

Now, an international team of scientists have taken a page from nature’s playbook to model micro-sized robots that use sound waves to coordinate into large swarms that exhibit intelligent-like behavior. The robot groups could one…

Scientists turn grapevine waste into clear, strong films that vanish in days

The need for biodegradable packaging material has never been higher. Currently, most packaging is “single use” and is made with plastic materials, derived from nonrenewable sources like crude oil that take hundreds of years to decompose in the environment.
