The fossils of ancient salamander-like creatures in Scotland are among the most well-preserved examples of early stem tetrapods -- some of the first animals to make the transition from water to land. Thanks to new research, scientists believe that these…

A new study finds that if global warming exceeds the Paris Climate Agreement targets, the non-polar glacier mass will diminish significantly. However, if warming is limited to 1.5 degrees Celsius, at least 54 per cent could be preserved -- more than twice as…

Spring in the Arctic brings forth a plethora of peeps and downy hatchlings as millions of birds gather to raise their young. The same was true 73 million years ago, according to a new article. The paper documents the earliest-known example of birds nesting in…

Long considered a disease brought to the Americas by European colonizers, leprosy may actually have a much older history on the American continent. Scientists reveal that a recently identified second species of bacteria responsible for leprosy, Mycobacterium…

Anthropologists have examined the societal consequences of global glacier loss. This article appears alongside new research that estimates that more than three-quarters of the world's glacier mass could disappear by the end of the century under current climate…

Scientists have documented the way a single gene in the bacterium that causes bubonic plague, Yersinia pestis, allowed it to survive hundreds of years by adjusting its virulence and the length of time it took to kill its victims, but these forms of plague…

A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope analysis from ancient South African rock cores. These…

New techniques used to analyze soft tissue in dinosaur fossils may hold the key to new cancer discoveries. Researchers have analyzed dinosaur fossils using advanced paleoproteomic techniques, a method that holds promise for uncovering molecular data from…

Researchers created a detailed physical model that suggests a major Atlantic Ocean current will weaken far less under climate change than indicated by more extreme climate model projections.

Lightweight, powerful lithium-ion batteries are crucial for the transition to electric vehicles, and global demand for lithium is set to grow rapidly over the next 25 years. A new analysis looks at how new mining operations and battery recycling could meet…

Replanting forests can help cool the planet even more than some scientists once believed, especially in the tropics. But even if every tree lost since the mid-19th century is replanted, the total effect won't cancel out human-generated warming.

Whether you are lucky enough to have a cat companion or must merely live this experience vicariously through cat videos, Felis catus is a familiar and comforting presence in our daily lives. Unlike most other feline species, cats exhibit sociality, can live in…

Scientists analyzed almost 200 cannabis genomes to create the most comprehensive, high-quality, detailed genetic atlas of the plant to date. The atlas reveals unprecedented diversity and complexity within the species, sets the stage for advances in…

Reducing travel speeds and using an intelligent queuing system at busy ports can reduce greenhouse gas (GHG) emissions from oceangoing container vessels by 16-24%, according to researchers. Not only would those relatively simple interventions reduce emissions…

Interactive robots should not just be passive companions, but active partners -- like therapy horses who respond to human emotion -- say researchers.

A new concept of kinetic modules in biochemical networks could revolutionize the understanding of how these networks function. Scientists succeeded in linking the structure and dynamics of biochemical networks via kinetic modules, thus clarifying a systems…

New research brings together 7,000 years of history in South Arabia to show how ancient pastoralists changed placement and construction of monuments over time in the face of environmental and cultural forces.

This study measured the growth rate of coral reefs in Honaunau Bay, Hawaii, using on-site data gathering and aerial imagery. Researchers found that the reefs are being eroded by sea urchin populations which have exploded due to overfishing in the area. The…

Researchers compared the whole genome sequence of two genetically distinct lineages of bed bug, and their findings indicate bed bugs may well be the first true urban pest.

Close to five million smuggled seahorses worth an estimated CAD$29 million were seized by authorities over a 10-year span, according to a new study that warns the scale of the trade is far larger than current data suggest. The study analyzed online seizure…

Palaeontologists have analyzed the most complete stegosaurian skull ever found in Europe and rewritten the evolutionary history of this iconic group of dinosaurs.

Chemists have demonstrated how RNA (ribonucleic acid) might have replicated itself on early Earth -- a key process in the origin of life.

Researchers find high-fat diets set off metabolic dysfunction in cells, leading to weight gain, but these effects can be reversed by treatment with an antioxidant.

A team identified herpes virus saimiri, which infects the T cells of squirrel monkeys, as a source of proteins that activate pathways in T cells that are needed to promote T cell survival.

In a major leap forward for genetic and biomedical research, scientists have developed a powerful new artificial intelligence tool that can predict the 3D shape of chromosomes inside individual cells -- helping researchers gain a new view of how our genes…

The timing and consistency of your daily activity might be associated with improved cardiorespiratory fitness and walking efficiency.

Scientists show that wolves that are eating sea otters in Alaska have much higher concentrations of mercury than those eating other prey such as deer and moose.

Many bat species native to Germany, such as the Leisler's bat, are forest specialists. However, as it is becoming increasingly hard for them to find tree hollows in forest plantations, so they are moving to settlements instead. Using high-resolution GPS data…

The aging of the innermost cell layer of blood vessels leads to cardiovascular diseases. Researchers have now shown for the first time that intestinal bacteria and their metabolites contribute directly to vascular aging. As people age, the bacterial…

A new study finds that chronic cannabis use -- whether it's smoked or consumed in edible form -- is associated with significant cardiovascular risks.
