Our understanding of which aquatic species produce sounds just took a big step forward. Scientists have created an inventory of species confirmed or expected to produce sound underwater.

Some coral species can be resilient to marine heat waves by 'remembering' how they lived through previous ones, research suggests.

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

A new study of natural capital finds nature's benefits to humanity are expected to decline as climate change shifts ecosystems across borders.

Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store.

The word 'drought' typically conjures images of parched soil, dust-swept prairies, depleted reservoirs, and dry creek beds, all the result of weeks or seasons of persistently dry atmospheric conditions. In the sun-soaked islands in the Caribbean, however, drought conditions can occur much more rapidly, with warning signs appearing too late for mediation strategies to limit agriculture losses or prevent stresses on infrastructure systems that provide clean water to communities.

Positive tipping points must be triggered if we are to avoid the severe consequences of damaging Earth system tipping points, researchers say.

An international team of scientists led by geneticists and disease biologists has used ancient DNA to trace the evolution of Marek's Disease Virus (MDV). This global pathogen causes fatal infections in unvaccinated chickens and costs the poultry industry over $1 billion per year. The findings show how viruses evolve to become more virulent and could lead to the development of better ways to treat viral infections.

Early 2024, the European Parliament will take a final vote on the 'Nature Restoration Law' (NRL), a globally unique but hotly debated regulation that aims to halt and reverse biodiversity loss in Europe. An international team of scientists has investigated the prospects of the new regulation.

Drones flying along miles of rivers in the steep, mountainous terrain of central Taiwan and mapping the rock properties have revealed new clues about how water helps shape mountains over geological time.

Researchers have increased the fatigue threshold of particle-reinforced rubber, developing a new, multiscale approach that allows the material to bear high loads and resist crack growth over repeated use. This approach could not only increase the longevity of rubber products such as tires but also reduce the amount of pollution from rubber particles shed during use.

Arctic seals have evolved many adaptations to cope with their frosty environment -- one that you might not immediately think of is the bones in their nasal cavity. Arctic seals have more convoluted nasal passages than seal species that live in milder environments, and researchers report that these structures help the seals more efficiently retain heat and moisture as they breathe in and out.

A research team is studying how expanding populations of two local herbivores -- reindeer and geese -- on Svalbard will impact the future of the ecosystem on the islands.

Researchers sought to investigate whether socioeconomically vulnerable households experienced longer power outage durations after extreme weather events. The team analyzed data from the top eight major Atlantic hurricanes between 2017 and 2020 that knocked out power for over 15 million customers in nine states across the southeastern U.S. The team found that people in lower socioeconomic tiers wait significantly longer to have power restored after a major storm -- nearly three hours longer on average.

Two new studies based on data from 2009 to 2018 show that renters living along the East and Gulf coasts of the United States face rent increases, higher eviction rates, and a lack of affordable housing in the aftermath of a hurricane.

With the holiday season in full swing, gifts of all shapes and sizes are being shipped around the world. But all that packaging generates lots of waste, including cardboard boxes and plastic-based foam cushioning. Rather than discard those boxes, researchers have developed a cushioning foam from cardboard waste. Their upcycled material was stronger and more insulating than traditional, plastic foam-based cushioning.

Beef operations that keep cattle on lifelong grass-based diets may have an overall higher carbon footprint than those that switch cattle to grain-based diets partway through their lives, according to new findings.

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it's likely been spoiled for generations.

Researchers have shown that the effects of wildfires are not limited to terrestrial ecosystems. Aquatic ecosystems are also undergoing rapid changes. The study found that fire debris transforms lakes and other aquatic ecosystems, with implications for fisheries and water quality.
