Strolling through a forest, you may notice that the air is filled with sound. Birds sing, insects and small mammals rustle through the undergrowth, and at dusk bats squeak as they communicate with each other.

Anthropogenic underwater noise is a growing concern for marine mammal populations, particularly where short-term behavioral disturbance may scale into longer-term population consequences. While individual responses to noise exposure are well documented, quantitative...

Imagine struggling to follow conversations in a noisy restaurant or keep up in a busy office, yet being told by a doctor that your hearing is fine. That is the frustrating reality for people living with cochlear synaptopathy, or hidden hearing loss.

Farmland biodiversity plays a crucial role in maintaining healthy ecosystems and productive agricultural landscapes. Yet across Europe, farmland birds – key indicators of environmental health – have suffered sharp declines as farming has intensified.

For the first time, scientists have used NASA's IXPE (Imaging X-ray Polarimetry Explorer) to directly measure the magnetic fields of PSR J1101−6101, a pulsar located within what is often referred to as the Lighthouse Nebula. The results provide new insight into the structure of some of the most extreme objects in the cosmos, as NASA continues to explore the secrets of how the universe works. A

Diabetes affects more than 800 million people worldwide and can cause a range of serious complications. Among the most challenging are diabetic foot ulcers – chronic wounds that resist healing and can lead to amputation or death if not treated effectively.

Federal accessibility requirements are only as effective as the local governments responsible for enforcing them.

Scientists using NASA's IXPE (Imaging X-ray Polarimetry Explorer) conducted more than 140 hours of observations of the magnetar 1E 1547-5408, between March and April 2025, alongside NASA's NICER (Neutron Star Interior Composition Explorer) and Murriyang, CSIRO's Parkes radio telescope, owned and operated by Australia's national science agency. This was the first-ever coordinated radio and X-ray polarization measurement of a magnetar.

Wetlands are surprisingly effective at locking away carbon. Marshes, floodplains and peatlands together cover less than a tenth of the Earth's surface, yet peatlands alone hold around a third of all the carbon stored in soil worldwide.
