Radiation

Solar wind – charged particles from the Sun – pervades our solar system, but the exact mechanism behind it remains murky. Now ESA’s Solar Orbiter spacecraft has observed previously unknown tiny flares on the Sun’s surface spewing plasma into space.

Scientists have discovered that the Sun produces higher energy light than was thought possible. An unusual type of telescope detected gamma rays with energies of over 1 tera electron volt, at least five times more energetic than previously known.

In a scary first, scientists have discovered a 2021 solar eruption so large that it was, for the first time, detected simultaneously on Earth, the Moon, and Mars, highlighting the radiation dangers posed by such events to deep space travelers.

More than 12 years after the Tōhoku earthquake and tsunami that cost Japan 20,000 lives, the IAEA has formally approved Japan's plan to release treated radioactive water from the damaged Fukushima Daiichi nuclear power station into the sea.

A new study has found that combining radiotherapy with a cancer-targeting virus was more effective at combatting a hard-to-treat, deadly form of brain tumor than using either therapy alone. The finding may lead to more effective cancer treatments.

Sinclair International has begun human trials of a new anti-radiation drug called HOPO 14-1 that is designed to help decontaminate those who have been exposed to radioactive elements as a result of a nuclear accident or dirty bomb attack.

A team of engineers has developed a new type of camera that can detect radiation in terahertz wavelengths. This new imaging system can see through certain materials in high detail, which could make it useful for security scanners and other sensors.

Tree rings can preserve a snapshot of the Earth throughout the tree's life. Now Australian scientists analyzing these records have found evidence of huge radiation storms that periodically bathe the planet – and their origin remains a mystery.

Engineers at Duke University have developed a novel delivery system for cancer treatment involving a radioactive implant, and demonstrated its potential against one of the disease’s most troublesome forms: pancreatic cancer.

The liver can regenerate itself after taking damage, but whether that ability fades with age is unknown. A new study has found that age doesn’t slow down the liver’s regeneration, and whether you’re 20 or 80, your liver is on average just three years old.

Analysis of an ongoing project that has been tracking the health of nearly one million women in the UK for more than 20 years has found no association between increased risk of brain tumors and cell phone use.

Stem cell transplants to treat blood cancers can be a risky process. In a new study in mice, researchers found a way to make the process safer by targeting a patient’s faulty stem cells more precisely, removing the need for radiation or chemotherapy.
