Gun-related deaths in NZ dropped after gun laws passed

Humans use lots of different types of information to make sure we don't get lost. We can look out for familiar landmarks and use our sense of direction, but we can also estimate how far we have walked.

Dental fear is an intense emotional reaction that can be characterized by anxiety, palpitations, sweating, dizziness, a feeling of unreality or nausea. It may cause some people to avoid going to the dentist, while others feel an intense urge to flee once they are there.

Maintaining balance while walking may seem automatic—until suddenly it isn't. Gait impairment, or difficulty with walking, is a major liability for stroke and Parkinson's patients. Not only do gait issues slow a person down, but they are also one of the top causes of falls. And solutions are often limited to time-intensive and costly physical therapy.

A cognitive behavioral therapy (CBT) program developed for parents whose child was born prematurely reduced harmful perceptions that their child remained medically fragile, according to a new study led by UT Southwestern Medical Center. Published in Pediatric Research, the study is the first to show that an intervention could lower parental perceptions of child vulnerability (PPCV), a critical factor in a child's development.

On Thursday 18 September 2025, a committee of the US Centers for Disease Control and Prevention (CDC) voted to recommend that children should receive multiple separate vaccines to protect against measles, mumps, rubella and chickenpox.

Mosquito-borne viruses can cause more than fevers and joint pain. In severe cases, they invade the brain, leading to seizures, encephalitis, lasting memory loss and sometimes death. But thanks to a new UCLA study, researchers have uncovered how some of these viruses breach the brain's defenses—and point toward ways of keeping them out.

The number of reported cholera cases is increasing in Darfur and more than 3,000 people across all of Sudan have died from the illness over the last 14 months of civil war, the U.N. health agency said Tuesday.

In behavioral research, it is largely assumed that people adapt their personal behavior to match the behavior of a reference group. A distinction is made between descriptive norms—the assumption that others behave in a certain way—and injunctive norms, where people believe that others expect them to behave in a certain way.

In a mouse model of liver transplantation, UCLA researchers have identified proteins that act as "protective switches" guarding the liver against damage occurring when blood supply is restored during transplantation, a process known as ischemia-reperfusion injury.

Cancer kills more than 500,000 Americans each year. But today, UC San Francisco researchers are revolutionizing what we thought we knew about how cancer spreads, opening new paths to cures. The paper is published in the journal Nature Cell Biology.

For immune cells, the actin cytoskeleton is more than a structural scaffold. Immune cells can migrate to sites of infection or form precise, short-lived contacts with other cells, by constantly reshaping their actin cytoskeleton. Genetic errors in the molecular machinery controlling actin dynamics lead to impaired immunity, and often to autoimmunity and chronic inflammation.

Qualified local optometrists can manage certain eye care conditions rather than those based at hospitals, significantly reducing patient waiting times and lowering costs for the NHS, a new study finds.

A study involving more than half a million adults has confirmed that the combination of cardiovascular, kidney, and metabolic conditions, collectively known as cardiovascular–kidney–metabolic (CKM) syndrome, substantially increases the risk of early death and serious illness. The findings highlight the urgent need for integrated care that treats these conditions together rather than in isolation.

Researchers examined problems related to the timing and scheduling of surgeries and patients' stays in recovery units. In collaboration with a hospital, they developed an integrated elective surgery assignment, sequencing, and scheduling problem (ESASSP) and devised new ways to solve it.

Costco has recalled more than 3,000 pounds of its Kirkland Signature Ahi Tuna Wasabi Poke after testing found a risk of listeria contamination.

There are over 100,000 fitness apps currently available on app stores, but despite the variety in choice, there has been little evidence they lead to real-world fitness improvements—until now.

A Novo Nordisk designed trial reports that their 25 mg oral semaglutide taken once daily produced greater mean weight reduction than placebo over 64 weeks in adults with overweight or obesity.

Music affects us so deeply that it can essentially take control of our brain waves and get our bodies moving. Now, neuroscientists at Stanford's Wu Tsai Neurosciences Institute are taking advantage of music's power to synchronize brain waves to boost the effectiveness of a technique called transcranial magnetic stimulation (TMS), a promising tool for both basic brain research and treating neuropsychiatric disorders.
