The appearance of Covid -19 in Italy and Iran surprised many this week. As the virus continues to spread we look at ways to contain it.Australia’s fires have burnt around 20 percent of the countries woodlands, what are the implications for the recovery of those ecosystems?And what is the link between the world’s super rich and deforestation? Unsurprisingly it’s money.And we hear about the unexpected cooling effects of hydroelectric dams.Weather: wet, dry, cold, hot, sunny, windy or downright weird -

2020/02/23

Roland Pease reports from the American Association for the Advancement of Science’s annual meeting in Seattle. At the UK Research and Innovation’s stand in the exhibition hall, he’s joined by three scientists to discuss monitoring the Coronavirus outbreak, the locusts devastating crops in East Africa and the ever increasing amount of space junk orbiting the Earth. Professor Jeffrey Shaman of the Mailman School of Public Health at Columbia University talks about how he is modelling the movement of

CoVid-19: Mapping the outbreak

Unexpected Elements ·

2020/02/16

Researchers at the London School of Hygiene and Tropical medicine have developed an online map which presents the latest information on the spread of CoVid-19 and allows anyone to follow the outbreak and compare this data with the spread of Ebola and SARS. See the weblink from this page to try it for yourself.And the coming together of microbiology and big data science has led to the development of a portable device able to spot antibiotic resistant bacteria. This should help with more precise drug

Coronavirus, prospects for treatment?

Unexpected Elements ·

2020/02/09

Doctors in the US have treated a coronavirus patient with a drug developed for Ebola. That drug had never been tested on people so its use here seems an extreme move. We look at why this kind of drug developed for one virus might work on another. It’s all down to the genetic material at the centre of the virus. That raises safety concerns as human cells contain similar material.East Africa is experiencing a plague of locusts and bizarrely it’s linked to the Australian wildfires. A weather pattern

Understanding the Wuhan coronavirus

2020/02/02

Parts of China are on lockdown, a small number of cases have been reported in other countries and the past week has brought widely conflicting views on the potential danger presented by the new virus. We look at the scientific facts, analyse why it’s so difficult to predict the spread of the virus, look at the nature of virus infection and discuss why treatments such as vaccines are not available. We look at why some viruses can jump from animals to humans and examine hi-tech solutions designed to

Wuhan Coronavirus

2020/01/26

The way in which a new virus has emerged in China is reminiscent of SARS, a highly infectious virus that spread rapidly. It’s so similar that Health officials demanded action as soon as its existence became known. And the Chinese authorities and global medical community have acted to try and stop the spread. Events were still developing, even as we were in the studio making this programme, new reports of suspected cases were coming in. The WHO was yet to give its view on the severity of the

An experimental satellite called Aeolus, named after a Greek god of wind, which takes daily global measurements of the wind patterns throughout the depth of atmosphere has improved weather forecasts. ESA’s Anne-Greta Straume explains how it works. The dramatic eruption of the island volcano Taal in the Philippines was a spectacular picture of the plume of ejecta punching a hole in overlying cloud cover. Nearby towns have been blanketed with dust, fissures have appeared in the ground and there has

Australia’s extreme fire season

2020/01/12

2019 was Australia’s hottest year on record, a major factor behind the bush fires which have been far worse than usual. We look at the patterns of extreme weather that have contributed to the fires but are also linked to floods in Africa. And the way in which thunderstorms have helped to spread the fires.The armpit of Orion is changing.

Roland Pease is joined by California based science Journalist Molly Bentley as we examine the impact of earthquakes and fires. California has experienced both in the last year - What’s it like to live with a constant threat from these extreme events? We also take a look at NASA’s plans for a new mission to Mars – to look for signs on life. What is empathy?

Gaming climate change

2019/12/29

The latest round of climate negotiations, COP25 have ended without agreement on many fundamental issues. We join researchers from Perdue University in the US who have developed a role playing game to encourage climate negotiators and others to take a long term view. Key to this research project is the concept of tipping points, where an environment changes irreversibly from one state to another. This is accompanied by the loss of ecosystems, for example the widespread melting of arctic sea ice,

As CrowdScience celebrates its third birthday, the team takes time to revisit some of our early episodes, and catch up with listeners to discover if the answers we uncovered changed the course of their lives?

Molecular scale investigations have identified the mechanism which confers resistance to antimalarial drugs. Researchers hope work to turn off this mechanism could mean cheaper well known antimalarials can become effective once again. We look at the threat to weather forecasting from 5G networks, discuss the origins of much of the technology in our mobile phones and ask what food we’ll be eating in the future and how the past can inform this.Science fiction is full of people settling on distant

The Santa Ana in the south, and the Diablo in the north, are winds that are fuelling the terrible fires raging in California this week. They’re also blamed for bringing down power lines that sometimes start the fires. Roland Pease talks to Janice Coen of the National Center for Atmospheric Research NCAR who has been developing a highly detailed model to forecast how wind, mountains, and flames interact during a wildfire.

A quantum computer has performed a calculation considered impossible for conventional computers, but how meaningful is the result? As our guest reveals, this quantum state can be hugely significant and garbage – at the same time.
