Climate change’s effects on ocean water temperatures and salinity could shrink sonar detection ranges underwater and make it more challenging to spot submarines
The balance of omega fatty acids in the food we eat affects our health. But what does the evidence say about claims you should be seeking to reduce omega-6 intake as well as boosting omega-3s?
AI can analyse satellite images to reveal the movements of dark ships in a shadow fleet that smuggles oil and other cargo from sanctioned countries such as Russia, Iran, Venezuela and North Korea
With severe climate impacts becoming more and more apparent, many scientists think we should explore ways to block out solar radiation, but doing so would be risky
A group of around 40 scientists signed a declaration calling for formal acknowledgement of consciousness in a range of animals, including insects and fish – but the evidence is still lacking
As work begins on building the US’s first high-speed rail service – linking Los Angeles to Las Vegas – analysts say the project could serve as a blueprint for similar projects across the country
In the 1920s, Erwin Schrödinger wrote an equation that predicts how particles-turned-waves should behave. Now, researchers are perfectly recreating those predictions in the lab
"Advanced recycling" promises to convert dirty, mixed waste plastic into brand new plastic time and time again. It is a major step towards creating a circular economy and fighting climate change
Rather than being an optional extra, dreams might be vital to our functioning Exposed, the undulating surface of the brain is shimmering and opalescent, punctuated with arteries and veins. Give any part of it the tiniest jolt of...
Shading the planet by spraying aerosols into the stratosphere might stave off ice sheet collapse, modelling studies suggest, but we are running out of time
Researchers adapted the "delay of gratification" test for Singaporean preschool children, offering insights into self-regulation development in Asian contexts. The research involved children choosing between smaller immediate rewards and...
A new study investigates why everyday actions like locking a door are often forgotten. Researchers explored how people tend to remember significant events rather than routine details.
Researchers made a significant discovery in understanding the mechanisms behind protein accumulation in neurodegenerative diseases like Alzheimer’s. By studying fruit flies, the team found that a reduction in mitochondria within neuron...
A new study revealed significant risks associated with antipsychotic use in dementia patients, including increased chances of stroke, heart failure, pneumonia, and other serious conditions. The research analyzed data from 173,910...
Research that aims to explain why some people experience intense visual imagery could lead to a better understanding of creativity and some mental disorders William Blake’s imagination is thought to have burned with such intensity that,...
20 April is weed's unofficial holiday. In honour of the special day, we collected our answers to all your cannabis questions. This is the science of 420
Cnicin, a compound derived from the plant Blessed Thistle, significantly enhances nerve regeneration. The study shows that Cnicin can accelerate the growth of axons, the long fibers of nerve cells, which is crucial for the recovery of...
It can be difficult to figure out how to move a spacecraft from one orbit to another, but a trick from knot theory can help find spots where shifting orbits becomes easy
Researchers initiated a pioneering clinical trial using an advanced form of CAR-T therapy, enhanced by synthetic notch (synNotch) technology, to treat glioblastoma. This trial represents a significant shift towards targeted, safer cancer...
Optical coherence tomography, commonly used in eye exams, can monitor neurodegeneration in Parkinson's disease patients by measuring the thickness of the retina. This method has revealed that retinal degeneration often precedes cognitive...
Researchers identified a novel mechanism that impacts memory formation through changes in DNA structure, specifically G-quadruplex DNA (G4-DNA). Their study reveals that G4-DNA accumulates in neurons, dynamically influencing gene...
In a discovery that could hasten treatment for patients with multiple sclerosis (MS), scientists have discovered a harbinger in the blood of some people who later went on to develop the disease.
Although there are still some aspects pending confirmation for its use in the clinical setting, and its resolution needs to be improved slightly, a study has shown that a method routinely used to carry out ophthalmological tests can also...
By measuring how birds’ vocal muscles move while they are asleep and using a physical model for how those muscles produce sound, researchers have pulled songs from the minds of sleeping birds
Researchers identified a specific pattern of autoantibodies in the blood that precedes the clinical onset of multiple sclerosis (MS), potentially paving the way for early diagnosis and treatment. Their study found that 10% of MS patients...
Identical twins seem to experience more similar levels of pleasure when listening to music than non-identical twins, which suggests it has a genetic element
Curved wing tips inspired by the world's heaviest flying bird could enhance the efficiency of wind turbines by of 10 per cent, according to simulations
A site in Siberia has evidence of human presence 417,000 years ago, raising the possibility that hominins could have reached North America much earlier than we thought
Teams of staff usually return e-scooters to where they will be needed, but adapted scooters that can balance and stop themselves, and be controlled remotely, are a step towards autonomous ones that can take themselves wherever they have...
Last year’s marine heatwaves saw an unprecedented decline in the growth of phytoplankton and algae, which many animals in the oceans depend on for food
Contrary to previous assumptions, nerve cells in the human neocortex are wired differently than in mice. The study found that human neurons communicate in one direction, while in mice, signals tend to flow in loops. This increases the...
Summary: Cannabinol (CBN), a cannabinoid derived from cannabis, offers neuroprotective properties that could treat neurological disorders like Alzheimer’s, Parkinson’s, and traumatic brain injuries. Their study details how...
Fibroblast growth factor receptor inhibitors, commonly used in cancer treatment, could effectively reduce neurological symptoms in patients with post-treatment Lyme disease syndrome. The study shows these inhibitors can decrease...
Researchers made significant advances in understanding how drugs like cocaine and morphine disrupt the brain's natural reward mechanisms. Their study reveals that these drugs manipulate the same brain cells responsible for processing...
Twin studies have proven invaluable for teasing out the effects of both genetics and the environment on human biology. Researchers studied pairs of twins to look at how the interplay of genetics and environment affect cognitive...
A sensitive perception of the environment is crucial for guiding our behavior. However, an overly sensitive response of the brain's neural circuits to stimuli can lead to neurodevelopmental disorders such as epilepsy. Researchers now...
