Darfur cholera cases rising at an 'alarming' rate as death toll in Sudan tops 3,000, says WHO

The brain never rests: even during deep sleep or under anesthesia, it maintains rhythmic electrical activity known as slow oscillations. A team from the Sensory-motor Processing by Subcortical Areas laboratory, led by Ramón Reig at the Institute for Neurosciences, a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University (UMH) of Elche, has discovered what determines the direction of these waves. The study, published in iScience, reveals that the key lies not in anatomical structure, as previously thought, but in the degree of neuronal excitability.

Infection rates from drug-resistant "nightmare bacteria" rose almost 70% between 2019 and 2023, according to a new report from Centers for Disease Control and Prevention scientists.

Dexterity, coordination and balance are all extremely important throughout our lives, but these skills change between early childhood and old age. At which stage of our lives do we have the best balance? Do fine and gross motor skills continue to decline with age?

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.

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.

Each year, firearms injuries are costing the New Zealand hospital system an average of $1.48 million and costing the country a further $321 million in years of life lost, a new study led by the University of Otago—Ōtākou Whakaihu Waka has found.

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.
