As the rollout of #Covid-19 vaccinations gathers pace, the mammoth task of inoculating billions of people across the globe has seen a number of unusual sites and buildings converted into #vaccination centres, from Disneyland in California, to an ancient UK cathedral and a bus converted into a mobile vaccination unit.
On its first day, the new Biden administration announced plans to recalculate the social cost of carbon—a way of estimating the economic toll of greenhouse gases. Staff Writer Paul Voosen and host Sarah Crespi discuss why this value is so important and how it will be determined.
Next up, Alison Barker, a postdoctoral researcher at the Max Delbrück Center for Molecular Medicine, talks with Sarah about the sounds of naked mole-rats. You may already know naked mole-rats are pain and cancer resistant—but did you know these eusocial mammals make little chirps to identify themselves as colony members? Can these learned local dialects make naked mole-rats a new research model for language learning?
A neuroprosthetic device restores blood-pressure control after spinal-cord injury, and identifying the neurons that help us understand others’ beliefs.
In this episode:
00:47 A neuroprosthetic restores the body’s baroreflex
A common problem for people who have experienced spinal-cord injury is the inability to maintain their blood pressure, which can have serious, long-term health consequences. Now, however, researchers have developed a device that may restore this ability, by stimulating the neural circuits involved in the so-called baroreflex.

10:58 A neuronal map of understanding others
Humans are very good at understanding that other people have thoughts, feelings and beliefs that are different to our own. But the neuronal underpinnings of this ability have been hard to unpick. Now, researchers have identified a subset of neurons that they think gives us this ability.

The saying goes that there are no new ideas out there. Every new invention is just a mashup of other things. But when it comes to E-bikes, who’s complaining? Extra juice to go with your pedal power? We’ll take it. And some serious breakthrough designs are coming in the industry, too. Let’s take a look at the contenders for the title of most innovative e-bike of 2021.

The “Son of Man” is an iconic painting by Belgian Surrealist artist Rene Magritte.
Rene Magritte was an internationally acclaimed surrealist artist of all time, yet it was not until his 50s, when he was finally able to reach some form of fame and recognition for his work. Rene Magritte described his paintings saying, “My painting is visible images which conceal nothing; they evoke mystery and, indeed, when one sees one of my pictures, one asks oneself this simple question, ‘What does that mean?’ It does not mean anything, because mystery means nothing, it is unknowable.”
Magritte was born in 1898, to a wealthy manufacturer father. In 1912, his mom was found drowned in the River Sambre. She had committed suicide, and the family was publicly humiliated because of it. From 1916 to 1918, Rene decided to study at the Academie des Beaux-Art, which was located in Brussels. He left the school, because he thought that it was a waste of time. All his paintings afterward reflect cubism, the movements which were introduced by Pablo Picass and was very popular at the time. In 1922 he married Georgette, and took a number of small jobs, including painting cabbage roses for a wallpaper company, in order to be able to pay the bills.
During the early period of his career, shortly following his marriage, Rene Magritte would spend the free time that he had, creating art forms and worked on a number of pieces; it was during this time period that he realized surrealism was the art form which he most enjoyed. The Menaced Assassin was one of his earliest pieces in 1926, which showcased the surrealist style which he had been working on; The Lost Jockey was another piece that he introduced in 1925, which also showcased this art form. Over the course of his career, he produced a number of variants on this piece, and changed the format to recreate what the viewer was experiencing.
Macular degeneration is a leading cause of visual impairment in people over 65 and can lead to blindness. One in three people will eventually suffer some degree of macular degeneration, which is caused by abnormal blood vessels under the retina, the light-sensitive part of the eye. We treat both the more common “dry” as well as the more dangerous “wet” forms of macular degeneration. While there is currently no cure for this disease, we offer the latest treatments to reduce the risk of vision loss and blindness. These include anti-VEGF drugs—which attack proteins that create the abnormal blood vessels that cause macular degeneration—and photodynamic therapy, in which patients ingest medication that is then activated with a laser.
Online News Editor David Grimm joins host Sarah Crespi to discuss a controversial new paper that estimates how many rodents are used in research in the United States each year.
Though there is no official number, the paper suggests there might be more than 100 million rats and mice housed in research facilities in the country—doubling or even tripling some earlier estimates.
Next, Staff Writer Jennifer Couzin-Frankel talks with Sarah about a new theory behind the cause of irritable bowel syndrome—that it might be a localized allergic reaction in the gut. Sarah also chats with Taline Kazandjian, a postdoctoral research associate at the Centre for Snakebite Research & Interventions in Liverpool, U.K., about how the venom from spitting cobras has evolved to cause maximum pain and why these snakes might have developed the same defense mechanism three different times.
