Peatlands will store more carbon as planet warms

New research suggests global warming will cause peatlands to absorb more carbon initially, but the effect will weaken as warming increases. The study highlights the importance of protecting intact peatlands and restoring drained peatlands to prevent rapid rates of peat decomposition.

Bird bacteria study reveals evolutionary arms race

A recent study has found that birds develop resistance to bacterial infections, which in turn leads to the evolution of more potent pathogens. This host-pathogen coevolution process plays a key role in shaping species' defenses and highlights the importance of understanding emerging infectious diseases.

Burly bird gets the worm

A study at the University of Exeter found that larger garden birds, such as house sparrows and greenfinches, dominate access to better food sources like sunflower hearts. Smaller bird species like blue tits and coal tits face limited access to quality food, pecking quickly to make the most of their time.

Beluga whales and narwhals go through menopause

Researchers discovered that beluga whales and narwhals undergo menopause, mirroring killer whales' behavior. This reproductive strategy may have evolved due to increased relatedness among family members and the need for older females to contribute to group survival through knowledge sharing.

Study confirms truth behind 'Darwin's moth'

Researchers found that pale peppered moths are more camouflaged against lichen-covered tree bark than dark moths, making them less likely to be eaten by birds in unpolluted woodland. This supports Darwin's theory of evolution by natural selection and provides key evidence for the evolutionary advantage of camouflage.

How hot is Schrödinger's coffee?

A new uncertainty relation has been discovered, linking the precision of temperature measurements to quantum mechanics. This discovery establishes a connection between quantum uncertainty and the accuracy of nanoscale thermometers.

World experts target guidance on managing dementia symptoms

New research suggests that non-drug approaches should be prioritised in treating agitation in people with Alzheimer's disease, ranking assessment and management of underlying causes as the top treatment. Non-pharmacological treatments such as person-centred care and tailored activity programmes are also recommended for managing symptom...

Stop antibiotics before resistance 'tipping point'

New evidence suggests that reducing antibiotic course length can reduce the risk of resistance. Microbial communities can reach a tipping point when exposed to antibiotics, leading to an irreversible shift towards drug resistance. Stopping treatment too soon may not prevent resistance from occurring.

Asian hornet nests found by radio-tracking

Scientists used tiny radio tags attached to Asian hornets to track them to five previously undiscovered nests in southern France and Jersey. The technique has the potential to help protect Britain's beleaguered pollinator populations from the invasive species' devastating impact on honeybees and other pollinators.

World's first animals caused global warming

Researchers found that early animals caused a decrease in oxygen levels and increase in carbon dioxide, leading to global warming. This process had a massive impact on the environment, contributing to mass extinctions during animal evolution's first 100 million years.

New hope from the 'seven year switch' in Type 1 diabetes

A study published in Diabetes Care found that the rapid decline in insulin production associated with Type 1 diabetes follows a two-phase pattern: an initial exponential fall and a subsequent stable phase. This discovery suggests that people with Type 1 diabetes may retain some working beta-cells for seven years after diagnosis.

Thousands of turtles netted off South America

New research reveals tens of thousands of sea turtles are caught each year by small-scale fishers off South America's Pacific coast, with over 16,000 killed. The study highlights Ecuador and Peru as key places to tackle this issue, which threatens critically endangered species like leatherbacks and hawksbills.

Mixed signals from poisonous moths

Scientists studied six-spot burnet moths to examine if natural variation in wing markings indicates toxicity levels. Smaller red forewing markings were associated with more cyanide in females but not males. The study suggests evolutionary pressures may be complex and drive colors beyond matching toxicity levels.

Cautious prawns win battle for food

Research by University of Exeter scientists found that cautious rockpool prawns are better at controlling a limited resource than bolder counterparts. This may be due to their risk-averse strategy, which involves staying near a food source rather than exploring new areas and risking competition with stronger rivals.

Goal conflict linked to psychological distress

Research at the University of Exeter and Edith Cowan University found that goal conflict and ambivalence are associated with symptoms of anxiety and depression. The study involved over 200 young adults aged 18-35, who reported experiencing psychological distress due to conflicting goals.
