Most of us have experienced unwanted calls at home. This is in spite of efforts by regulators, including the Information Commissioner’s Office and Ofcom, whose most recent report shows that around half of the UK population still receive nuisance calls. Many of these unsolicited calls annoy us because they interrupt our dinner or favorite TV show – but some, such as sales or scam calls, can cause distress or even harm.

Pluto, along with many other dwarf planets in the outer solar system, is often thought of as dark, icy and barren – with a surface temperature of just −230°C.

But now a new study, published in Nature Geoscience, suggests that the body has had a warm interior ever since it formed, and may still have a liquid, internal ocean under its icy crust.

It could mean that other sizable icy dwarf planets may have had early internal oceans too, with some possibly persisting today. This is exciting, as where there’s warm water, there could be life.

Video of police in riot gear clashing with unarmed protesters in the wake of the killing of George Floyd by Minneapolis police officer Derek Chauvin has filled social media feeds. Meanwhile, police surveillance of protesters has remained largely out of sight.

Most public restrooms are grungy in the best of times. Now, we have the coronavirus risk to contend with, too. There are lots of risks – dirty sinks and door handles, airborne particles and other people in small, enclosed spaces who may or may not be breathing out the coronavirus.

A teenager held her phone steady enough to capture the final moments of George Perry Floyd’s life as he apparently suffocated under the weight of a Minneapolis police officer’s knee on his neck. The video went viral.

What happened next has played out time and again in American cities after high-profile cases of alleged police brutality.

When the coronavirus pandemic really started to take hold in the UK in March, news consumption increased, as in many other countries. But, since then, our research shows that an increasing share of the UK population is switching off from the news.
