On 18th February the Perseverance rover should land on Mars. Katie Stack-Morgan of NASA’s Jet Propulsion Lab tells Roland Pease about the technological advances that mean that the spacecraft should be able to land in Jezero Crater. Imperial College geologist Sanjeev Gupta discusses what this crater can reveal about the history of life on the red planet.

After months of negotiations, and weeks of work on the ground, a team brought together by the World Health Organisation has just concluded its first attempts to find out the origins of SARS-Cov2 in Wuhan. Peter Daszak, who has worked closely with Chinese virologists in the past, briefed Roland Pease on what had been discovered.

The South African government has announced that it will not be rolling out the Astra Zeneca Covid vaccine as it appears it is not very effective against the dominant strain in the country. Helen Rees, of Witwatersrand University and a member of South Africa’s Health Products Regulatory Authority, explains that the ‘ban’ is an overstatement.

At least 35 people died in a flood disaster in the Himalayan state of Uttarakhand in India on February 6th. The details are still unclear, but the trigger seems to be associated with a glacier overhanging an upstream lake in the steep valley. Rupert Stuart-Smith of Oxford University, who has just published an analysis of a glacier melting disaster in waiting in the Andes, talks about the impacts of climate change on the stability of mountain glaciers.

And Do you find your bearings quickly or are you easily disorientated? Do your friends trust you with the directions in a new city? Finding our way in the physical world – whether that’s around a building or a city - is an important everyday capability, one that has been integral to human survival. This week CrowdScience listeners want to know whether some people are ‘naturally’ better at navigating, so presenter Marnie Chesterton sets her compass and journeys into the human brain. Accompanied by psychologists and neuroscientists Marnie learns how humans perceive their environment, recall routes and orientate themselves in unfamiliar spaces. We ask are some navigational strategies better than others?

Marnie also hears that the country you live in might be a good predictor of your navigation skills and how growing up in the countryside may give you an wayfaring advantage. But is our navigational ability down to biology or experience, and can we improve it?

With much of our modern map use being delegated to smartphones, Marnie explores what implications an over-reliance on GPS technology might have for our brain health.

Archival records may help researchers figure out how fast the sea level is rising in certain places. Millions of people in coastal cities are vulnerable to rising sea levels and knowing exactly how fast the water is rising is really important. But it's a tough scientific question. NPR climate correspondent Lauren Sommer explains how scientists are looking to historical records to help get at the answer.

Global Witness documented that 212 environmental and land activists were murdered in 2019. Over half of those documented murders took place in Colombia and the Philippines, countries where intensive mining and agribusiness has transformed the environment. NPR Short Wave reporter Emily Kwong speaks with three activists about the intersection between natural resource extraction and violence, and what keeps them going in their work.

Why is it so hard to feel the difference between 400,000 and 500,000 COVID-19 deaths—and how might that impact our decision making during the pandemic? Psychologist Paul Slovic explains the concept of psychic numbing and how humans can often use emotion, rather than statistics to make decisions about risk.

Three in 10 people in America have a tattoo, and those in the 18 - 34 age bracket, it's almost 40 percent. But what's in those inks, exactly? NPR science correspondent Nell Greenfieldboyce talks about what researchers currently know about tattoo inks. It's not a lot, and researchers are trying to find out more.
