A flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied...

Fossil-fuel plants are increasingly being forced to stop and start production in response to changes in output from renewables. In a new study, researchers developed a dynamic competitive benchmark that accounts for start-up costs and other unit-level operating constraints. They apply their framework to Western Australia, a setting where rooftop solar capacity more than doubled between 2014 to 2018 to world-leading rooftop solar penetration rates. The study found that the... Read more ›

Exposure to antibiotics during a key developmental window in infancy can stunt growth of insulin-producing cells in the pancreas and may boost risk of diabetes later in life, new research in mice suggests. The study also pinpoints specific microorganisms that may help those critical cells proliferate. Read more ›

For human health, prematurely aging cells are a big problem. When a cell ages and stops growing, its function changes, which can cause or worsen cardiovascular disease, Alzheimer's disease and other chronic diseases. But these cells are also like needles in a haystack, difficult to identify by traditional scientific measures. Read more ›

How is organic matter transported from productive coastal areas to the open ocean? Researchers have now shown that eddies play a crucial role in this process. The swirling currents contain large amounts of energy-rich and essential fat molecules (essential lipids), which play a key role in marine food webs and the carbon cycle. Read more ›

A drug typically prescribed for arthritis halts brain-damaging seizures in mice that have a condition like epilepsy, according to researchers. If the drug proves viable for human patients, it would be the first to provide lasting relief from seizures even after they stopped taking it. Read more ›

Scientists have discovered a promising way to trigger immune responses against certain tumors, using a lupus-related antibody that can slip, undetected, into 'cold' tumors and flip on an immune response that has been turned off by cancer. The research offers new findings that could help improve therapies for glioblastoma and other aggressive cancers that are difficult to treat. Read more ›

Mothers experience major metabolic adaptations during pregnancy and lactation to support the development and growth of the new life. Although many metabolic changes have been studied, body temperature regulation and environmental temperature preference during and after pregnancy remain poorly understood. Researchers show that postpartum female mice develop new environmental temperature preferences and reveal brain changes mediating these changes. Read more ›

Plastic is everywhere in our daily lives. And much of what we use, such as cutting boards, clothes and cleaning sponges, can expose us to tiny, micrometer-wide plastic particles called microplastics. Now, chewing gum could be added to the list. In a pilot study, researchers found that chewing gum can release hundreds to thousands of microplastics per piece into saliva and potentially be ingested.

Early animal studies show that a single vaccine could protect the recipient from different variants of the coronaviruses that cause COVID-19, the flu and the common cold. In addition to creating antibodies that target a specific region of the spike protein that doesn't mutate, the vaccine removes the sugar coat from the virus that allows it to hide in the body.

Deep below the Earth's surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, environments. Read more ›

Tiny fragments of plastic have become ubiquitous in our environment and our bodies. Higher exposure to these microplastics, which can be inadvertently consumed or inhaled, is associated with a heightened prevalence of chronic noncommunicable diseases, according to new research. Read more ›

The condition of the grass on a golf course can drastically skew the chances of a winning putt regardless of a player's skill. Now, a coating that soaks up water molecules could slow the roll of a golf ball on a lightning-fast, dry course and speed it up on a sluggish, wet course without interfering with the ball when it's airborne.

A new study has uncovered evidence of far-reaching ecosystem consequences following the disappearance of Great white sharks (Carcharodon carcharias) from False Bay, South Africa. The research spans over two decades and documents cascading ecological disruptions, underscoring the crucial role apex predators play in maintaining ocean health. Read more ›

Crashes on electric scooters are mostly due to the behavior of the riders, with one-handed steering and riding in a group being some of the largest risk factors. The researchers are also concerned about riders who deliberately crash or cause dangerous situations when riding, a phenomenon that seems to be specific to electric scooters. Read more ›
