Published Ritual use of human remains dating from the Neolithic



An international study has documented post-mortem bone modifications not linked to consumption.
Published How to tackle the global deforestation crisis



New research examines the 'revolution' in the study of deforestation brought about by satellites, and analyzing which kinds of policies might limit climate-altering deforestation.
Published Ancient Amazonians intentionally created fertile 'dark earth'



A new study suggests patches of fertile soil in the Amazon, known as dark earth, were intentionally produced by ancient Amazonians as a way to improve the soil and sustain large and complex societies.
Published Archaeologists discover world's oldest wooden structure



Half a million years ago, earlier than was previously thought possible, humans were building structures made of wood, according to new research.
Published Prehistoric fish fills 100 million year gap in evolution of the skull



X-rays of an ancient jawless fish shows earliest-known example of internal cartilage skull, unlike that of any other known vertebrate.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction



A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Researchers discover a new species of larger benthic foraminifer from the Ryukyu Islands



An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.
Published The pace of climate-driven extinction is accelerating



Studying a lizard species in Arizona mountains, researchers found 70 years' worth of climate-related extinction occurred in only seven years.
Published Buried ancient Roman glass formed substance with modern applications



Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals -- ordered arrangements of atoms that filter and reflect light in very specific ways -- an analog of materials used in communications, lasers and solar cells.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens


Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration


• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Rivers are rapidly warming, losing oxygen; aquatic life at risk



Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.
Published Pollination by more than one bee species improves cherry harvest



To obtain the biggest cherry harvest, trees should be pollinated by both honey bees and mason bees. This new study shows yet another benefit of biodiversity.
Published How just one set of animal tracks can provide a wealth of information



Rock faces in Namibia are decorated with hundreds of stone-age images not only of animals and human footprints, but also of animal tracks. These have been largely neglected to date as researchers lacked the knowledge required to interpret them. Archaeologists have now worked together with animal tracking experts to investigate the engraved animal tracks on six rock faces in more detail, and were able to determine detailed information on the species, age, sex, limbs, side of the body, trackway and relative direction of the tracks.
Published Earth's stability and ability to support civilization at risk: Six of nine planetary boundaries exceeded



A new study updates the planetary boundary framework and shows human activities are increasingly impacting the planet and, thereby, increasing the risk of triggering dramatic changes in overall Earth conditions.
Published Shipboard cannon found off the Swedish coast may be the oldest in Europe



Maritime archaeologists have studied what might be Europe's oldest shipboard cannon. The cannon was found in the sea off Marstrand on the Swedish west coast and dates back to the 14th century. The findings from the interdisciplinary study contribute new knowledge about the early development of artillery on land and at sea, but also bears witness to a troubled period for seafarers as well as coastal populations.
Published Protected nature reserves alone are insufficient for reversing biodiversity loss



Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.
Published Some spiders can transfer mercury contamination to land animals


Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
Published More Texas owls are testing positive for rat poisons


New research suggests that owls in Texas have high rates of anticoagulant rodenticides (AR) -- blood thinning rat poisons -- in their systems.
Published Freshwater connectivity can transport environmental DNA through the landscape


A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
