An analysis of changes to global ecosystems has revealed that almost nowhere is untouched by the influence of humanity, with more than 50 per cent of the planet’s land mass experiencing “novel” conditions An analysis of changes to global ecosystems has revealed that almost nowhere is untouched by the influence of humanity, with more than 50…
Brook trout may have a genetic trick up their scales when it comes to adapting, with limitations, to heat waves that threaten their existence. Scientists have known for years that brook trout—an iconic coldwater fish species native to streams and lakes in the eastern United States and Canada—are extremely vulnerable to warming temperatures, with more…
About 90% of flowering plants rely on animals to transfer their pollen and optimize reproduction, making pollination one of nature’s most important processes.

An international team of paleontologists, geoscientists and biologists has found via analysis of melanosome patterns in fossilized Mesozoic mammals, that they most likely had dark, uniformly dull fur coloring. In their paper published in the journal Science, the group describes how they created a predictive model to analyze melanosome patterns found in fossilized fur samples. An…

Hydrology experts at Flinders University are calling for urgent investigations into the operation of bore-fields that access fresh groundwater on Pacific islands, including Kiribati, where rising sea levels are already putting local water supplies at risk.

SARS-CoV-2, the virus responsible for COVID-19, infects cells by binding its spike protein to angiotensin-converting enzyme 2 (ACE2) receptors. Blocking this interaction with inhibitors could prevent infection. Since these inhibitors act directly on the virus without affecting human cells, they may be safer than some existing treatments. However, mutations in the spike protein can alter…
Scientists have found a new way to navigate beams of light through dynamic scattering media, such as the turbulent atmosphere or living tissue.

A newly developed laboratory tool can, within hours, help to identify specific viruses which can be used to destroy variants of the dangerous pathogenic bacteria Staphylococcus aureus. Viruses of bacteria, known as bacteriophages, offer an alternative approach to antibiotics in treating multiresistant pathogens.
