The iconic tusked whale of the Arctic has a new enemy -- noise. A unique study shows that narwhals are highly affected by noise from ships and seismic airgun pulses -- even at 20-30 kilometers away. As ice melts, noise levels in the Arctic are rising, worrying scientists about the future of narwhals.

Drugs developed to treat AIDS and HIV could offer hope to patients diagnosed with the most common form of primary brain tumor. The breakthrough is significant because, if further research is conclusive, the anti-retroviral drugs could be prescribed for patients diagnosed with meningioma and acoustic neuroma brain tumors (also known as schwannoma).

A new study has shown how the brain gives credit to events, along with how transcranial ultrasound (TUS) can disrupt this process. While currently developed in an animal model, this line of research and the use of TUS could one day be applied to clinical research to tackle conditions such as addiction.

Researchers uncover a single rule for how animals make spatial decisions while on the move.

Birds and humans have very different networks of neurons in their brains. Nevertheless, their working memory is limited by similar mechanisms.

Scientists have developed a pioneering new technique to barcode individual cells more accurately and efficiently - which could help pave the way for quicker disease diagnosis.

Why are some individuals able to use recreational drugs in a controlled way, whereas others switch to the compulsive, relapsing drug-seeking and -taking habits that characterize substance use disorder (SUD)? Despite more than six decades of extensive research, the question remains unanswered, hampering the development of targeted prevention and therapeutic strategies. Now, a new study in rats has identified the maladaptive nature of drug-seeking habits and how they contribute to the perpetuation of addiction by promoting the tendency to relapse.

Perovskites are the great hope for further increasing the efficiency of solar modules in the future. Until now, their short service life has been considered the biggest hurdle to their practical use, but this could soon change. Researchers now present a variant that stands out for its stability.

Genes that make bacteria resistant to antibiotics can persist longer than it was previously believed. This was recently shown in a new study that reports a previously unknown hiding place for these genes. The finding represents a new and important piece in the puzzle to understand how bacterial antibiotic resistance works.

Ammonium is one of the specific components of fine particulate matter (PM2.5), that has been linked to a higher risk of death compared to other chemicals found in it, according to a new study.

While farmers have the capacity to drive species conservation worldwide, their true potential is yet to be fully realized. An international team of researchers shows how this can change. The researchers interviewed 560 farmers around the world to find out what they know about their local pollinator diversity and their engagement in the issue. The results offer important insights for politics and science.

Researchers have developed a method to generate embryo-like cell complexes from the stem cells of mice. The method provides new insights into embryonic development. In the medium term, it might also be suitable for developing tests for substances that could be harmful to fertility.

As climate change makes periods of record low snow more frequent, a new study helps to bridge disagreement over how to measure snow depth and how to define snow drought.
