Secrecy is a huge part of military success. You want to be able to communicate with your own forces without the enemy finding out what your plans are.
As America entered World War II, they were in need of a method of communication that couldn’t be cracked by Germany or Japan. They found the answer they were looking for in the languages of Native Americans.

Former Trump press secretary Stephanie Grisham famously held no press briefings during her time in the White House — but now, she's ready to talk. Her memoir, I'll Take Your Questions Now, is the latest tell-all from a former Trump staffer — and Tamara Keith, from NPR's Politics Podcast, hit her with some tough questions about whether the book is simply an image rehab project. "Too many books have been out there to help one person's reputation so they can be rehabilitated ... or to try to rewrite history," Grisham says. "I just want to tell my story and have people take what they want from it."
To explore the universe humans have made any manner of telescopes. These telescopes can observe visible light, infrared light, radio waves, and even x-rays.
One of the most important forces in shaping the universe is gravity. How can astronomers observe gravity?
In 2002, the National Science Foundation, Caltech, and MIT managed to build a gravitational observatory.
When Colin Powell died on October 18 at the age of 84 from COVID-19 complications, he left behind a long, decorated career in Washington and the U.S. Army. He spent much of his life in the military, eventually rising to the rank of four-star general, and went on to become the first Black Secretary of state and chairman of the Joint Chiefs. But, as he discussed in a 2012 interview with NPR's Robert Siegel about his memoir It Worked For Me, Powell's reputation was tarnished when he used faulty evidence to push for the Iraq War: "I'll never leave it behind."
Weather systems on Earth aren’t stable. There are cycles that weather patterns go through which can have enormous effects around the globe.
There is probably no more important weather cycle than the one meteorologists called the Southern Oscillation. This cycle can have dramatic implications for temperatures and rainfall all over the world.

Batteries are powering the electric car revolution, but can we make them longer lasting, faster charging and smaller and lighter? Beyond electric cars and other vehicles, the more applications means more renewable energy can be stored and used, driving us away from fossil fuels. Tom Heap visits UKBIC - the UK Battery Industrialisation Centre in Coventry - a vast facility to develop better batteries. He dons full protective gear to see some of the processes involved in making batteries and testing new chemistries and engineering. He speaks to Isobel Sheldon from British Volt about the goals and potential that could be realised by improving batteries and climate scientist Dr Tamsin Edwards assesses how much carbon dioxide this could potentially save.

How well is your country doing? The GDP - gross domestic product - has long been a measure of growth and success but some argue judging purely on economics is too narrow-sighted.
Tom Heap meets 'chopsy' Sophie Howe, the Future Generations Commissioner for Wales who will challenge if a decision being made will be detrimental for children and those yet to be born. If the cost and inheritance to them is high it risks getting kicked out. She takes him to the wetlands she helped save from a planned M4 development. Katherine Trebeck explains alternatives measures of national success, the factors they take in and why many feel happier about using them. Dr Tamsin Edwards assesses what an alternative viewpoint could do for carbon cutting.

Generating renewable energy from solar power has been a great resource but land for this purpose can come into conflict with other uses or receive opposition from those who don't enjoy the view. But can floating solar panels on water - which accounts for most of the surface of the planet - provide an alternative?
Tom Heap meets Mark Bennett, a farmer from Berkshire, who created a reservoir for soft fruit production and was curious to see if it had more potential. After a quick internet search he went to visit Ciel et Terre, a French company who were developing floating solar panels. He installed them for power at the farm and to demonstrate to others. Meanwhile the company founder Bernard Prouvost talks to Tom about the countries around the world which are adopting this, where he feels floating panels are appropriate and if the potential to partner with hydrodams. Climate Scientist Dr Tamsin Edwards assesses their carbon cutting potential.

There are different schools of thought on how land (and sea) are best managed but often in the rush for economic development indigenous practices and knowledge are overlooked. Observations and understanding from living on the land can inform how to protect and preserve it . Tom Heap meets Victor Steffensen, a descendent of the aboriginal Tagalaka people and an indigenous fire practitioner. He explains how cultural burns can help manage the land, reduce the fuel load and the likelihood of destructive wildfires. Yet he feels while there are calls to incorporate this knowledge more, it doesn't go far enough. Diana Mastracci is a researcher working with groups in the Amazon and Arctic to give them equal participation and benefits from research and runs hackathons for software ideas that could use and value their knowledge more and says academics have a long way to go to fully appreciate this knowledge.
Dr Tamsin Edwards weighs up just how much carbon dioxide could potentially be saved by adopting indigenous land management practices.

Flying, for business or pleasure, has long been seen as one of the biggest carbon villains. As airports gear up again after Covid it's clear not every business wants to keep meetings online or holidaymakers settle for a staycation.
But what if we could fly without the guilt? Tom Heap meets some of the pioneers of zero carbon flight: hitching a ride with Harbour Air in Canada who have retrofitted one of their planes to fly on electric battery power; visiting the equivalent of the Batcave with a Bristol company making EVTOLs - electric vertical take-off and landing vehicles - which could see us zipping between cities; and asking about the use of sustainable aviation fuels. Dr Tamsin Edwards joins him to discuss how much carbon dioxide - and more - this could potentially save.
