Heat energy leaps through empty space

A surprising new study shows that heat energy can leap across a few hundred nanometers of a complete vacuum, thanks to a quantum mechanical phenomenon. It could have profound implications for the design of computer chips and other nanoscale electronic components.

Borisov is the first identified comet from another star

Comet 2I/Borisov is only the second interstellar object known to have passed through the solar system. This mysterious visitor from the depths of space is the first identified comet to arrive here from another star.

Too Much More Microplastic in the Ocean Than We Realized

If you pulled 1,000 liters of water out of the ocean, how many small bits of plastic would you expect to find? Ten pieces? One hundred pieces? 8.3 million pieces of what researchers call "mini-microplastic" is the finding of an alarming new study.

Physicists 'See' Gravitational Waves From Deeper in the Universe

A new method, the result of decades of research, has allowed researchers to suppress vacuum noise and extend the reach of the gravitational wave detectors.

Our BPA Exposure Is Much Higher Than We Thought

BPA or Bisphenol A (a toxic ingredient in plastic products) levels on might be far higher then we previously tested, a new study, that used new device to measure levels of the common industrial chemical in our bodies, suggests 

Reducing Air Pollution Saves Lives in Just Weeks

In the US,  a 13-month closure of a steel mill in Utah resulted in reducing hospitalizations for pneumonia, pleurisy, bronchitis and asthma by half. School absenteeism decreased by 40 percent, and daily mortality fell by 16 percent.

A New Record for the Most Massive Black Hole Ever Seen

Astronomers have measured a 40 billion solar mass black hole in the Holm 15A galaxy. Their results could lead to even more massive black holes.

An Organism That Thrives on Eating Meteorites

The discovery of Metallosphaera sedula - the bacteria that eats meteorites not only invites speculation on how terrestrial life could survive off world, it offers insight into how early biology could have received key nutrients through space rocks.

SpaceX Launched Its Last Rocket of the Decade to the ISS

Four in five teens do not exercise enough: WHO

More than 80% of global teens don't get at least one hour of daily exercise, according to a UN health agency study. The findings have implications for physical and mental health as well as youth education.

Smart devices score poor marks on recycling

E-waste is a global problem, while the mining of fresh resources for electronics leaves devastation in its wake. And yet, the more cutting-edge our devices, the harder they are to recycle.

The truth about airplane carbon offsetting

A 2017 report for the European Commission looking at carbon offsetting found that 85% of offset programs failed to deliver "real, measurable and additional" emission reductions, and noted that some projects would have happened anyway.
