When whizzing through the Martian air, NASA’s pint-sized Mars helicopter sometimes stirs up a dust cloud that envelops and travels along with the tiny chopper. The unexpected phenomenon has scientists salivating over what it will teach us about the dynamics of Mars’s thin atmosphere, where tornado-like dust devils often form when the Sun heats the air and afternoon winds begin to blow. Ingenuity’s only goal is to show that flight on Mars is possible. So “anything we can learn from it scientifically is icing on the cake”, says physicist Brian Jackson.
The CureVac vaccine has proved to be only 47% effective in preventing COVID-19 in late-stage trials. CureVac, a German biotechnology company, pointed to the challenges of protecting against an “unprecedented broad diversity of variants” — 13 variants were detected among the people involved in the study, and only one person was infected with the original strain. The interim results have not yet been peer reviewed.

Three astronauts have moved into China’s space station, following the launch of the country’s first crewed spaceflight in nearly five years. They will be the first humans to visit the station. The crew will bring the station’s core module, Tianhe, into service. “We need to set up our new home in space,” said mission commander Nie Haisheng.

Quirks of our evolution might explain why humans need to drink more water than most mammals. While our ancestors were evolving in Africa two to three million years ago, the climate became more arid. Their bodies became taller and slimmer, with a greater surface area. Combined with a reduction of body hair and increase in sweat glands, this made them better at dissipating heat. But it also increased the amount of water that our ancestors needed. “Throughout history people have drastically engineered their environments to ensure access to water” as a result, writes human biologist Asher Rosinger.
