#Science of #Silicon avec la #MonicaGrady

Silicon
In Our Time

Misha Glenny and guests discuss the physics, biology and chemistry of the element silicon which is at the heart of some of the most useful and beautiful objects on the planet. While it is still being created throughout the universe, the silicon we have here was made billions of years ago in dying stars. In its compounds we have long used silicon for glass and, more recently, purified silicon has become the foundation of modern electronics. Perhaps less appreciated is the role silicon compounds play in the biology of life on Earth, on the levels of carbon dioxide in the atmosphere and the cycling of elements between land, oceans and atmosphere that sustains us.

What is RFK doing to vaccines for children in America?
Americast

A federal judge has temporarily blocked the Trump administration from making big changes to vaccines for children in the United States. It’s a blow to Health Secretary Robert F Kennedy - RFK Jr - a longtime vaccine sceptic who was given free rein by Donald Trump to “go wild with health”.

Since taking office a year ago, Kennedy has sought to slash the number of recommended shots for children from 17 to 11. The American Academy of Paediatrics and other large medical groups have sued, saying Kennedy's changes violate federal law and are based on ideology instead of science.

In this episode, Marianna and Justin unpack what this means for Donald Trump’s big plan
to - as he puts it - "Make America Healthy Again” with Dr Debra Houry, the former director of the CDC (Centre of Disease Control and Prevention) who resigned in August 2025.

(rapid decrease in the number of transplant surgeons)

The battle for hearts and lungs: Transplants in trouble.
File on 4 Investigates

The UK was once a world leader in heart and lung transplantation. Pioneering surgeons attracted patients from all over the world. But the NHS has not kept pace with medical and technological developments and today the UK lags far behind most similar countries. It carries out fewer transplants and a lack of resources mean it doesn’t routinely use modern technologies. Many of the health service’s leading surgeons have left to work overseas in recent years, frustrated, they say, at the lack of attention transplant services have received from NHS England.

Through speaking to patients, surgeons and experts, File on Four Investigates looks at what the UK needs to do to update and transform this life-changing service.

Who is Benjamin Netanyahu?
Profile

Benjamin Netanyahu was born in Tel Aviv in 1949, the year after the State of Israel was founded. One of three brothers, Netanyahu spent much of his early years in the United States pursuing his education.

But following his older brother’s death, Netanyahu found himself drawn into a career in the public eye. Using his military experience to advise on security matters, in 1984 Netanyahu became Israel’s Ambassador to the UN and established himself as a champion of Israel on the international stage. But soon, his attention was drawn closer to home.

He returned to Israel and entered the world of politics; in 1993, he became the leader of the Likud party, and was elected prime minister in 1996, a position he's held for much of the following decades.

During his time in power Netanyahu has tried to portray himself as Israel’s protector. However, in recent years, allegations of corruption and lapses in national security have damaged his reputation and polarised Israelis' views about him. His handling of the conflict in Gaza following Hamas’ October 7th attacks has drawn criticism at home and abroad.

Now, Netanyahu has joined forces with the US president Donald Trump to conduct what they termed as ‘major combat operations’ against Iran. But will this war restore Netanyahu’s reputation as ‘Mr Security’, or draw Israel into another intractable conflict?

Mark Coles profiles the longest-serving Israeli prime minister.
