Sound bullets in water

Scientists develop a device that can form and control sound bullets in water, with potential uses for underwater imaging and biomedical applications. The device, inspired by Newton's cradle, focuses high-amplitude pressure pulses into compact sound bullets that can be tightly focused on a target area.

Pond skating insects reveal water-walking secrets

Researchers have discovered the mechanism behind pond skaters' ability to walk on water. They use their middle leg to create swirling vortices, similar to those made by oars in a rowing boat, allowing them to move forward without sinking. The waxy hairs covering their legs also repel water and help generate an upward force.

More than 60 percent of people in low- and lower-middle income regions are not accessing any appropriate epilepsy treatment

A study finds that more than 60% of people in low- and lower-middle income regions are not accessing any appropriate epilepsy treatment. The burden of epilepsy in these regions is estimated to be at least double that found in high-income countries, with inadequate facilities for diagnosis, treatment, and ongoing management.

Parents find terms 'large' or 'gaining too much weight' less offensive than 'obese'

Medical researchers at the University of Alberta found that parents prefer terms like 'large' or 'gaining too much weight' when discussing their child's weight, rather than the term 'obese'. This suggests that using more neutral and descriptive language can reduce stigma and improve the physician-patient relationship.

Has the speediest pulsar been found?

Researchers using Chandra X-ray Observatory and XMM-Newton have found a point-like object, IGR J11014, which may be a rapidly spinning, super-dense star ejected during a supernova explosion. If confirmed, its speed of millions of miles per hour poses a challenge to existing models for supernova explosions.

First Nations and low-income children visit emergency departments more often for mental health care

A study found that First Nations children and those from families receiving government subsidies had significantly more visits to emergency departments for mental health crises. These visits were often due to anxiety- or stress-related disorders, emotional or behavioural issues from substance abuse, or unspecific diagnoses.

Cosmic calculations

A University of Delaware-led research team has developed more accurate calculations for the interactions between molecules of hydrogen and carbon monoxide, essential for spectroscopy in astrophysics. These advancements enable researchers to analyze molecular clouds where stars are born with greater precision.

A cannibalistic galaxy with a powerful heart

The closest large elliptical galaxy to the Milky Way, Centaurus A has a twisted disc of dust near its centre, formed from a cosmic collision with another galaxy. The galaxy's powerful heart features two massive jets streaming from a massive black hole, emitting strong radio emission and visible in far-infrared images.

Combating counterfeit medicines

Counterfeit medicines pose significant health risks, and experts argue that the World Health Organization (WHO) should play a key role in combating them. The authors propose an international treaty on medicine quality under WHO auspices to address this issue.

Recent advance in detonation theory

Researchers Hu et al. developed a new detonation model named the least-action detonation model (LADM) that takes into account complex movement and transport effects, differing from the classical ZND model. The LADM model predicts detonation product particles to be in a stationary state, which has been observed in experiments.

Cloudy with a chance of sudden death

Bioengineers from Rice University are testing a new law of biology to predict when critically ill patients will worsen, and which treatment is likely to prevent it. The study aims to provide clinicians with a patient-specific 'forecast' using data from electrocardiograms and other vital signs.

Robot biologist solves complex problem from scratch

A team of scientists has successfully demonstrated a computer's ability to analyze raw experimental data from a biological system and derive the basic mathematical equations that describe its operation. This achievement marks one of the most complex scientific modeling problems solved completely from scratch by a computer.

Pale people may need vitamin D supplements

Researchers at the University of Leeds found that people with fair skin are more likely to have sub-optimal vitamin D levels. The study suggests that these individuals may need vitamin D supplements to maintain optimal health levels, particularly in areas with limited sunlight.

Age gap really does matter

A Northwestern University study reveals that successful academics struggle to mentor students during the latter half of their careers. The research, analyzing 60 years of mathematicians and their advisees, found that mentors who advised fewer students had more successful protégés.

Caltech researchers create 'sound bullets'

Researchers at Caltech develop a nonlinear acoustic lens producing highly focused sound bullets for advanced medical imaging, nondestructive evaluation, and potentially even cancer treatment. The device exploits particle contacts to create compact acoustic pulses with high amplitude and low distortion.

For better trade, give peace a chance

A new study published in Conflict Management and Peace Science suggests that peace is a vital ingredient for trade to flourish, rather than trade leading to peaceful relations. The authors found that conflict reduces trade and that ignoring this relationship can produce biased estimates.
