Sky has been given exclusive access to a lab at St Thomas's Hospital that can identify the cause of an illness in just one test. Sky’s Victoria Seabrook went along to see how it works.

Why your brain can't always trust its own senses. And no, we don't live in a matrix.

Pain, color, and awareness—is any of it truly real? Explore the science of illusions and blindsight to uncover how your brain stitches together sensory data to build a complex, sometimes deceptive, simulation of reality.

Extreme heat kills more Americans than any other weather-related hazard. In Phoenix, heat kills more people than homicides each year.

The city is turning to an unlikely lifesaver: bags of ice. And the fire department is creating a new model in the battle against heatstroke.

Special correspondent Ben Tracy of Climate Central shows how this low-tech approach is saving lives. His story is part of our series, Tipping Point.

DW journalist Jonas Gerding is at an Ebola treatment center in Mongbwalu in eastern DR Congo — documenting the hypervigilance, prep, and anonymity kept by its tireless health workers.

In a much closer contest than previous years – when the tardigrade and the common earthworm won with popular landslides – the winner of the 2026 Guardian Invertebrate of the year has been decided.

A new personalised vaccine given in combination with an immunotherapy drug has stopped skin cancer returning in patients during a trial.

This could be a major moment in cancer treatment. But how did it work - and what could it mean for future patients?

Take a look back at some of the best scenes from your favourite shows, such as the octopus who can walk on land in The Hunt and the deadly Portuguese man-of-war from Blue Planet II.

After months stuck in the Strait of Hormuz, hundreds of vessels have set sail with hulls colonized by marine life. A new scientific study warns the ships could help invasive species leap between ecosystems. The authors describe it as a potential marine "bio-invasion superspreader event" that could threaten fisheries and coastal habitats worldwide.

The bigger an animal is, the more calories it needs to sustain itself - the easiest way to do that is by eating small things like leaves, plants, and krill.

This TEDx talk explores the fragile relationship between humans and wildlife through a deeply personal story from rural Tanzania, where nightly encounters with elephants can mean fear, loss, and even death. This talk aims to reframe human–elephant conflict not as a battle to be won, but as a communication problem to be solved. It highlights an unexpected solution, beehive fences, inspired by research from conservation biologist Lucy King, to show how designing with nature, rather than against it, can protect communities while allowing wildlife to thrive. 

Over 2,400 people have contracted measles in the United States so far this year, topping the total number of cases for 2025 in just seven months. At the same time, vaccination rates have been declining, and there’s a lot of conversation about what’s driving vaccine hesitancy and how to combat misinformation.

Elisabeth Marnik has lived in both worlds: She wasn't vaccinated as a kid because her parents were concerned that vaccines could do harm. In high school, she fell in love with science. She went to college, got vaccinated, and then earned a PhD in immunology. She joins Flora to talk about what people misunderstand vaccine hesitancy, and how she approaches science communication in today’s messy information ecosystem.

Do the beavers have a better dam system?

Remembering the Dollys who changed the world.

Cancer can hide from your body’s natural defenses. Here’s how scientists are helping your body fight back.

Australian scientists have developed a system that could help reduce the impact of warming waters and protect vulnerable coral reefs.

101 East meets the researchers behind innovations that could potentially help safeguard the world’s reefs from the climate crisis.

DR Congo has begun vaccinating against its largest and deadliest recorded Ebola outbreak. However, the vaccine has not been proven effective against the Bundibugyo strain, which has killed 2,786 people out of 5,795 confirmed cases since May.

Ebola outbreaks can be contained, but ending them is another story. Conflict, fragile healthcare systems, and limited access to vaccines give the virus new chances to spread. Stopping one outbreak helps prevent the next.

South African scientist’s breakthrough research shows soil fungus could be used in fight against devastating crop pest

Speed, stealth, teamwork and extraordinary ingenuity, every hunter has a strategy! Across land and water, discover the remarkable tactics animals use to find and capture prey in this 4K compilation featuring original narration by David Attenborough.

Some people just seem to be mosquito magnets; in one scientific study, 20 percent of the people ended up with 95 percent of the mosquito bites! So if you’ve ever thought mosquitoes had it out for you specifically, you might be right. And now, we know why.

Antidepressants don't make people happy overnight. Instead, they slowly change how brain cells communicate, helping worn-down neural circuits recover over time. Here's why they take weeks to work, and why they help millions of people.

The Guardian's global health correspondent, Kat Lay, spoke to CDC Africa's Yap Boum II to understand why health teams on the ground are struggling and what is being put in place to try to contain the spread

It doesn't have sharp teeth or claws, but the mosquito kills more people than any other animal on Earth. As the climate warms, mosquito season is lasting longer, giving them more time to spread dangerous diseases. Ben Tracy with Climate Central reports on why the insects are thriving, and the surprising way scientists are fighting back.

The DNA in twins is (almost) exactly the same.

So how could a team of forensic scientists tell which twin committed the crime?

There is a way but it has some issues...
