An autoimmune response may contribute to hypertension

A new study suggests that an autoimmune response may contribute to the development of high blood pressure. Using mouse models, researchers found that compounds stimulating hypertension led to the faulty production of modified proteins in dendritic cells, triggering an immune response.

Habitual Facebook users more likely to be caught in phishing scams

A study published in the Journal of Computer-Mediated Communication found that habitual Facebook users are more likely to accept strangers as friends and give them personal information. This is because Facebook's design fosters habit formation and users with large social networks, frequent use, and impulsive behavior are more susceptib...

Reinterpreting dark matter

A team of researchers, led by Tom Broadhurst, has reinterpreted cold dark matter as a Bose-Einstein condensate, proposing that it governs the formation of the universe's structure. The theory predicts galaxies formed relatively late and could explain puzzling cores in dwarf galaxies.

New MRI technique helps clinicians better predict outcomes following mild traumatic brain injury

A new MRI technique using Diffusion Tensor Imaging (DTI) can help clinicians predict the likelihood of poor clinical outcomes following mild traumatic brain injury. This technique shows significant differences in white matter between mTBI patients with positive versus negative findings on CT and MRI evaluation.

Brain imaging research pinpoints neurobiological basis for key symptoms associated with post-traumatic stress disorder like listlessness and emotional detachment in trauma victims

A new study by NYU Langone Medical Center identifies a specific neurobiological basis for key symptoms of post-traumatic stress disorder (PTSD), including sadness, emotional detachment, and listlessness. The research uses brain imaging to link an opioid receptor in the brain to these symptoms, suggesting a potential target for personal...

The mobility model is closely linked to the city's characteristics

According to a study by the University of the Basque Country, the mobility model is closely linked to the city's characteristics. The study found that compact towns and cities have lower private vehicle use, better public transport offers lead to less car usage, and higher per capita income is associated with greater private car use. T...

Lunar explorers will walk at higher speeds than thought

Researchers studied astronauts' movements in low gravity and found that they could maintain higher speeds while walking on the moon. The team used NASA's DC-9 aircraft to simulate lunar gravity and tested the speed at which walkers transitioned from a walk to a run, discovering an average speed of 1.4m/s, exceeding previous estimates.

Failed Medicare payments law remains relevant

Despite Congress's adjournment, the Sustainable Growth Rate (SGR) Repeal and Medicare Provider Payment Modernization Act of 2014 remains a crucial issue in healthcare finance. Experts, including Dr. Eli Adashi, advocate for bipartisan efforts to address the SGR law and promote reforms to move Medicare towards quality-based compensation.

Transparent larvae hide opaque eyes behind reflections

Marine species use reflectors on scales to reduce contrast with background, but tiny mantis shrimp larvae hide compound eyes behind brilliant eye reflections that match surrounding water spectrum. Lab tests show little contrast between eye reflections and environment, revealing potential role for larval eyeshine in camouflage

Recruiting bacteria to be technology innovation partners

A Harvard team has created a novel protein engineering system called BIND to engineer bacteria into living foundries for the production of biomaterials with specific functions. The researchers have demonstrated the ability to fuse multiple proteins to create multifunctional biofilms that can be programmed to perform various tasks.

Cape Cod saltmarsh recovery looks good, falls short

Despite visible signs of recovery, Cape Cod's saltmarshes are not fully restoring their ecosystem functions. A new study found that recovering marshes provide only partial benefits in terms of wave exposure and sediment height, while always-healthy marshes continue to offer superior coastal protection.

Nile River monitoring influences northeast Africa's future

Curtin University research monitors Nile River water volume to help 200 million North-East Africans plan for sustainable use of resources. The study uses GRACE satellite data to isolate total water storage, providing independent insights for countries to inform decision-making and reduce reliance on the river's precious water supply.

Nanoscience makes your wine better

Researchers at Aarhus University developed a nanosensor to measure the effect of astringency in wine, allowing for better control over taste. The sensor uses salivary proteins to mimic mouth sensations, expanding understanding of astringency and its impact on wine quality.

New branch added to European family tree

A new study by Harvard Medical School and University of Tübingen reveals that present-day Europeans descend from three ancestral groups: Ancient North Eurasians, Basal Eurasians, and Near Eastern farmers. Genetic analysis found that Northern Europeans have more hunter-gatherer ancestry while Southern Europeans have more farmer ancestry.

Survey finds benefits, risks of yoga for bipolar disorder

A new survey of over 70 people with bipolar disorder suggests that yoga can have a substantial impact on reducing anxiety, promoting calm, and improving emotional well-being. However, some respondents also reported potential risks, such as physical injury or pain, and the need for caution in certain practice styles.

Peacock's train is not such a drag

Researchers found no significant difference in take-off performance between peacocks with and without their iconic trains. Despite initial expectations, the elaborate plumage does not seem to be a costly sacrifice for male birds. However, it may still affect flight stability and running ability.

A link between Jacobsen syndrome and autism

A recent study found that symptoms of autism were unusually common in people with Jacobsen syndrome, a rare genetic disorder affecting approximately 1 in 100,000 people. The study suggests that knowing this connection can help families investigate early intervention treatments to support their children.
