Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.

A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.

There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science.

Weed killers of the future could soon be based on failed antibiotics. Researchers have found a molecule which was initially developed to treat tuberculosis but failed to progress out of the lab as an antibiotic is now showing promise as a powerful foe for weeds that invade our gardens and cost farmers billions of dollars each year.

Species known as marine habitat-forming species -- gorgonians, corals, algae, seaweeds, marine phanerogams, etc.-- are organisms that help generate and structure the underwater landscapes. These are natural refuges for other species, and provide biomass and complexity to the seabeds. But these key species in marine ecosystems are currently threatened by climate change and other perturbations derived from human activity. Now, a study warns that even in the marine protected areas (MPAs) the genetic diversity of structural species is not protected, although it is essential for the response and adaptation of populations to changes that alter the natural environment.

A team of engineers has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air. Researchers describe the 'generic Air-gen effect'-- nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity. The secret lies in being able to pepper the material with nanopores less than 100 nanometers in diameter.

A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.

A new study has shown that human T cells have an important role to play in controlling infection.

Scientists have found evidence that microplastics in the digestive tract of seabirds altered the microbiome of the gut -- increasing the presence of pathogens and antibiotic-resistant microbes, while decreasing the beneficial bacteria found in the intestines.

Scientists have uncovered new clues about the origin of paired appendages -- a major evolutionary step that remains unresolved and highly debated.

Armadillos have long been considered to be the only living mammals that produce protective bony plates. But a new study unexpectedly shows that African spiny mice produce the same structures beneath the skin of their tails, which until now had gone largely undetected.

Seaside residents and holidaymakers have felt it for centuries, but scientists have only recently started to investigate possible health benefits of the coast. Using data from 15 countries, new research confirms public intuition: Living near, but especially visiting, the seaside is associated with better health regardless of country or personal income.

A new study has revealed that drying laundry using a condenser tumble dryer leads to hundreds of tons of potentially harmful microfibers being released into waterways and oceans across the UK and Europe.

Scientists have successfully conducted a simultaneous marine and atmospheric measurements at multiple locations directly beneath a violent, Category 5, which is the strongest class, typhoon in the North-West Pacific, before it reached land.
