Tam O'Shaughnessy and Sally Ride, the first American woman in space, met as kids in the early 1960s and developed an instant connection. Years later, they fell in love. They also were dedicated to STEM education and founded Sally Ride Science in 2001, a company focused on equity and inclusion in science education. Tam talks about this, and her relationship with Sally Ride, with Maddie Sofia. (encore)

Should we worry about the most recent Omicron subvariants, BA 4 and BA5? They are the subtypes of the Covid-19 virus now dominant in southern Africa and spreading elsewhere. New research suggests that they are better at evading our antibody defences than other forms of the virus. Columbia University virologist David Ho explains the findings and what they means for us. Also, reducing air pollution makes agricultural crops grow better, how large wildfires warm the upper atmosphere, and the dolphins in the Red Sea which use secretions from corals and sponges as preventative medicines.

This week’s CrowdScience is dedicated to bodily fluids – and why humans spend so much time spraying them all over the place. From snot and vomit to sweat and sneezes, listeners have been positively drenching our inbox with queries. Now presenter Marnie Chesterton and a panel of unsqueamish expert guests prepare themselves to wade through…

One listener has found that as he ages, bright light seems to make him sneeze more and more – with his current record sitting at 14 sneezes in a row. He’d like to know if light has the same effect on other people and why?

Sticking with nasal fluids, another listener wants to know why she’s always reaching for a tissue to blow her endlessly dripping nose and yet her family seem to produce hardly any snot at all. Could it be because she moved from a hotter climate to a colder one?

CrowdScience reveals the answers to these and other sticky questions… if you can find the stomach to listen.

Today, we're passing the mic to our friends at It's Been A Minute. Recently, they dug into how the anticipated repeal of Roe v. Wade will affect broader privacy issues. Will tech platforms continue to provide the same information, in states where the procedure is outlawed? What risk does your digital footprint create, if you seek information about abortion or other reproductive health care? Guest host Elise Hu talks it out with Rachel Cohen, senior policy reporter at Vox News, and Lil Kalish from CalMatters.

The knowledge economy. Intellectual property. Software. Maybe even bitcoin. All pretty much intangible, and yet all clearly real and genuinely valuable. This is the realm where economist Jonathan Haskel of Imperial College London mints his own non-physical scholarship. “In the old days,” relates the co-author of Capitalism without Capital: The Rise of the Intangible Economy, “the assets of companies, the sort of secret sauce by which companies would generate their incomes and do their services for which they’re employed for, was very tangible-based. These would be companies with lots of machines, these would be companies with oil tankers, with buildings, with vehicles to transport things around. Nowadays, companies like Google, like Microsoft, like LinkedIn, just look very different.” And that difference, he explains to interviewer David Edmonds in this Social Science Bites podcast, is knowledge. “What they have is knowledge,” says Haskel, “and it’s knowledge assets, these intangible assets, which these companies are deploying.”

Intangible investments, as you might expect, have different properties than do tangible ones. Haskel dubbed them the four S’s:

• Scale. Once you have a handle on a successful intangible, like software, that can generally scale up without more capital spending;
• Sunk Costs. These are invested costs you can’t get back, such as the costs of developing software;
• Spillovers. Aspects of your intangibles that others can copy or adopt for themselves; and
• Synergies. “If you put all these intangibles together,” he explains, “you get more than the sum of the parts.”

Meanwhile, intangibles help keep modern economies humming – we think. “Accountants and statistical agencies are quite reluctant to measure intangibles because it’s -- intangible. It’s a rather difficult thing to get at; these are often goods that aren’t traded from one person to another …”

Part of Haskel’s research effort is to quantify how much investment in intangibles is going on “behind the scenes,” which fits in with other interests of his such as re-engineering how gross domestic product gets measured. Businesses are now spending more on intangibles then on tangibles: Haskel’s work reveals that for every monetary unit companies spend on tangible assets, they spend 1.15 on intangible ones.

In addition to serving as a professor at the Imperial College Business School, Haskel is director of the Doctoral Programme at the Imperial. He is an elected member of the Conference on Research in Income and Wealth and a research associate of the Centre for Economic Policy Research, the Centre for Economic Performance, LSE, and the IZA, Bonn.

Haskel has been a non-executive director of the UK Statistics Authority since 2016 and an external member of the Bank of England’s Monetary Policy Committee since 2019.

Parkland, Fla. Buffalo, NY. Uvalde, Texas. Every mass shooting in the U.S. raises calls for better policies to prevent such tragedies. There's evidence suggesting that certain kinds of laws may reduce deaths from mass shootings, say scientists who study the field — but those policy options are not the ones usually discussed in the wake of these events. Furthermore, the amount of resources devoted to studying gun violence is paltry compared to its public health impact.

Recent rule changes have increased access to abortion pills through the mail, using telehealth services. As many U.S. states gear up to restrict abortion access in anticipation of the Supreme Court possibly overturning Roe v. Wade, the medical professionals behind these services are preparing for an even bigger surge in demand. Groups that provide abortion pills are also preparing to face significant new obstacles, as anti-abortion states push back against expanded online access. Both patients and clinicians are testing the boundaries of this service that is fully legal in many states — but operates in a legal gray area in others.

This week Science in Action comes from a vast gathering of earth scientists in Vienna, at the general assembly of the European Geosciences Union.

Roland Pease hears the latest insights into the cataclysmic eruption of Hunga Tonga in the Pacific ocean from volcanologist Shane Cronin of the University of Auckland. He also talks to NASA's Michael Way about how the planet Venus might have acquired its hellish super-greenhouse atmosphere, and how the same thing could happen to planet Earth. There’s intriguing research from geologist John Tarduno of the University of Rochester that hints of a link between the ups and downs of the Earth’s magnetic field and the evolutionary history of animals. Fraser Lott of the UK's Hadley Centre explains his ideas for calculating an individual person's responsibility for climate change-driven extreme weather events.

On Crowd Science, why can't I find gold in my back yard?

If you go outside with a spade and start digging, the chances are you won't find any gold. You might get lucky or just happen to live in a place where people have been finding gold for centuries. But for the most part, there'll be none. But why is that? Why do metals and minerals show up in some places and not others?

It's a question that's been bothering CrowdScience listener Martijn in the Netherlands, who has noticed the physical effects of mining in various different places while on his travels. It’s also a really important question for the future – specific elements are crucial to modern technology and renewable energy, and we need to find them somewhere.

Marnie Chesterton heads off on a hunt for answers, starting in a Scottish river where gold can sometimes be found. But why is it there, and how did it get there? Marnie goes on a journey through the inner workings of Earth's geology and the upheaval that happens beneath our feet to produce a deposit that’s worth mining.

On the way she discovers shimmering pools of lithium amongst the arid beauty of the Atacama Desert, meets researchers who are blasting rocks with lasers and melting them with a flame that’s hotter than the surface of the sun, and heads to the bottom of the ocean to encounter strange potato-sized lumps containing every single element on Earth.

And maybe, just maybe, she’ll also find gold.
