Researchers have discovered that breathing affects pupil size, with the pupil being smallest during inhalation and largest during exhalation. This newly identified mechanism is independent of external stimuli and could influence vision...
Rock dust, compost and biochar can all help capture carbon dioxide and boost crop yields when spread on soil – but researchers are discovering they may be even more effective when used in combination
The US withdrawal from the World Health Organization formally takes one year, but the country has already stopped sharing influenza surveillance with the international body, which could impact the efficacy of the next flu vaccine
Researchers have applied a visualization technique to depict the brain's activity related to visual perception as geometric patterns. They visualized different shapes as the ever-changing neuronal activity in the temporal and frontal...
Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation -- something that could affect our...
Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing fetus and forms a strong barrier...
Researchers have investigated how microbubbles tiny gas bubbles can deliver drugs into cells in a targeted manner using ultrasound. For the first time, they have visualized how tiny cyclic microjets liquid jets generated by microbubbles...
Tasmanian devils are already being released inside predator-proof sanctuaries in New South Wales, and rewilding advocates believe they could suppress feral cats and foxes across the continent
Physicists use mathematical assumptions in many situations that forbid time from moving backwards – but that isn’t necessarily a reflection of quantum reality
New observations have dramatically reduced the chances of asteroid 2024 YR4 hitting Earth in 2032, lowering the risk to minimal levels, but its extraordinarily close approach will offer astronomers the chance to examine it in detail
A new AI-based method can accurately recover digital data from DNA strands nearly 90 times faster than older techniques, raising the possibility of practical DNA storage for computing
Seeking mental health help is a significant step, but that first intake session can often feel more like paperwork than progress, and a significant proportion of people 'drop out' or never return for a second visit, previous research has...
Human evolution has revolved around food, from identifying and foraging for it to growing and preparing it. Researchers have identified a region in the brain's visual cortex that responds to food and have developed a theoretical...
Fetal acetaminophen exposure increases the likelihood that a child will develop attention-deficit/hyperactivity disorder (ADHD), according to a new study.
In a monthly reporting call on global climate, researchers from the US government’s climate and weather agency avoided mentioning rising levels of greenhouse gases
Repurposing amlodipine, a commonly used blood pressure medicine, could help manage attention-deficit/ hyperactivity disorder (ADHD) symptoms, according to an international study.
A new study analyzes the disease burden and the risk factors for severity among people who suffer from a condition called cannabinoid hyperemesis syndrome. Researchers say the condition occurs in people who are long-term regular...
Narcissists feel ostracized more frequently than their less self-absorbed peers, according to researchers. This may stem not only from being shunned due to their personalities but from a tendency to misinterpret ambiguous social signals...
A longer paternity leave after the birth of a child can improve the co-parenting relationship between moms and dads in a key way, a new study finds. Researchers found that mothers were less likely to discourage fathers' involvement in...
With the goal of informing clinician practice, a new study explores the harms and benefits of continuing and of discontinuing the long-term prescription of opioid medicines to adults with chronic pain.
A new study shows that enhancing activity of a specific component of 'NMDA' receptors normalizes protein synthesis, neural activity and seizure susceptibility in the hippocampus of fragile X lab mice.
When focusing in noisy environments, the brain adjusts not by concentrating harder but by ignoring distractions that were previously disruptive. Researchers developed a neural network model showing that people fine-tune their attention...
Researchers have identified two distinct groups of neurons that help the brain evaluate risk and reward in decision-making. These neurons, located in the ventral striatum, separately process better-than-expected and worse-than-expected...
Questioning a chatbot that has been trained on bestselling books from a particular decade can give researchers a measure of the social biases of that era
In new video footage, cuttlefish show off their dazzling camouflage techniques, such as creating stripes that move over their bodies or mimicking non-threatening objects
A red supergiant star appears to have changed in just a few years – an astronomical blink of an eye – which suggests it may be getting ready to explode in a supernova
Researchers found that Buddhist jhāna meditation and Christian speaking in tongues, despite their differences, share a common cognitive feedback loop. This process, called the Attention, Arousal, and Release Spiral, creates a cycle where...
Scientists have identified a key protein, AP2A1, that may hold the secret to reversing cellular aging. The study found that suppressing AP2A1 in older cells led to rejuvenation, while overexpressing it in young cells accelerated senescence.
The Trump administration’s pause on US foreign assistance could lead to an estimated 4.2 million unintended pregnancies and more than 8300 pregnancy-related deaths
Clinical research suggests that combining a novel agent called navtemadlin with DNA-damaging chemotherapy for the treatment of glioblastoma, a form of brain cancer, could increase efficacy. Navtemadlin is an MDM2 inhibitor that can help...
A new exhibition at Somerset House in London, SOIL: The World at Our Feet, wants us to rediscover how key soil is to our lives and to the planet’s future
In Feedback's true crime exclusive, we look into calls for a fresh inquest into the murder of Catherine Eddowes in the 19th century – and discover that a rather crucial part of the puzzle may be missing
Humans learn very differently to machines, thanks to our biased, malleable memory – and that's a good thing, says Charan Ranganath, director of the Dynamic Memory Lab at the University of California, Davis
Millions of years after humans vanish, fossil clues showing how we lived and dominated the planet may confuse future civilisations, says a new book by Sarah Gabbott and Jan Zalasiewicz
The opioid epidemic endangers not only public health but also social and economic welfare. Growing clinical evidence indicates that chronic use of prescription opioids may contribute to an elevated risk of ischemic stroke and negatively...
Pyramidal cells (PCs) in CA1 hippocampus can be classified by their radial position as deep or superficial and organize into subtype-specific circuits necessary for differential information processing. Specifically, superficial PCs...
