In this episode:00:45 A recyclable 3D printing resin from an unusual sourceMany 3D printers create objects using liquid resins that turn into robust solids when exposed to light. But many of these are derived from petrochemicals that are difficult to recycle. To overcome this a team has developed a new type of resin, which they’ve made using a bodybuilding supplement called lipoic acid. Their resin can be printed, recycled and reused multiple times, which they hope could in future contribute to

Now, a team of researchers have made a breakthrough in the development of these clocks, identifying the correct frequency of laser light required to make this energy transition happen. Ultimately it’s hoped that physicists

Talking about sex and gender doesn't need to be toxic

2024/05/02

Ever since scientific enquiry began, people have focused mainly on men, or if studies involve animals, on male mice, male rats or whatever it may be. And this has led to gaps in scientists’ understanding of how diseases, and responses to treatment, and many other things might vary between people of different sexes and genders.These days, mainly thanks to big funders like the NIH introducing new guidelines and mandates, a lot more scientists are thinking about sex and, where appropriate, gender.

They reveal a link between geographical locations and specific genetic mutations, suggesting that there are as-yet unknown environmental or chemical exposures in different locations. They hope this

Many people around the world feel lonely. Chronic loneliness is known to have far-reaching health effects and has been linked to multiple conditions and even early death.But the mechanisms through which feeling alone can lead to poor health is a puzzle.

Now, researchers have developed a portable optical clock and demonstrated its robustness by sending it on a perilous sea journey. The team hope that this work will pave the way to more practical uses of optical clocks, such as on satellites where they could help improve the accuracy of

In this episode:00:46 Mapping ‘ghost roads’ in tropical forestsAcross the world, huge numbers of illegal roads have been cut into forests. However, due to their illicit nature, the exact numbers of these roads and their impacts on ecosystems is poorly understood. To address this, researchers have undertaken a huge mapping exercise across the tropical Asia-Pacific region. Their findings reveal over a million kilometers of roads that don’t appear on official maps, and that their construction is a key

Around the world, rates of cancers that typically affect older adults are increasing in those under 50 years old. Models based on global data predict that the number of early-onset cancer cases like these will increase by around 30% between 2019 and 2030.The most likely contributors — such as rising rates of obesity and early-cancer screening — do not fully account for the increase. To try and understand the reasons behind this trend, many researchers are searching for answers buried in studies that

Now researchers have found an inflammatory pathway that responds to DNA damage in neurons has a key role in the persistence of memories. How this pathway helps memories persist is unclear, but the researchers suggest that how the DNA damage is repaired may play a role. As inflammation in the brain is often associated with disease, the team were surprised by this finding, which they hope

The deep haunting tones of the world's largest animals, baleen whales, are iconic - but how the songs are produced has long been a mystery. Whales evolved from land dwelling mammals which vocalize by passing air through a structure called the larynx - a structure whichalso helps keep food from entering the respiratory system. However toothed whales like dolphins do not use their larynx to make sound, instead they have evolved a specialized organ in their nose. Now a team of researchers have
