How should governments offer subsidies for clean-energy heating?

A new study from Aalto University recommends that government subsidies for clean-energy heating be allocated to areas where homeowners can least afford the upfront cost, namely those with lower housing prices. This approach aims to promote energy-efficient heat pumps and reduce carbon emissions in Finland's residential buildings.

Alternate-day intermittent fasting leads to less fat loss than traditional daily energy restriction

A new study suggests that alternate-day intermittent fasting may offer no unique health benefits over a standard daily diet. In contrast, traditional daily energy restriction resulted in greater weight and fat loss. The researchers note that longer studies with larger groups are needed to confirm these findings.

How do we know where things are?

Researchers at Dartmouth College discovered that the brain uses a 'steadycam' strategy to stabilize visual experience, perceiving frames as stationary even when they're clearly moving. This 'paradoxical stabilization' effect creates the illusion of stable images, similar to how our brains discount motion in everyday life.

Most rivers run dry -- now and then

A new study found that between 51-60% of the world's rivers stop flowing periodically, highlighting the need for a paradigm shift in river science and management. Non-perennial rivers provide critical water sources and support biological diversity, but are often overlooked and mismanaged.

Over-the-counter fungicide can disrupt hormones

A recent study by the National Food Institute found that clotrimazole, an over-the-counter fungicide, can significantly alter sex hormones in pregnant rats and their developing fetuses. This exposure was observed at concentrations comparable to those experienced by human mothers taking clotrimazole to treat vaginal thrush. The research...

How a supermassive black hole originates

A team of researchers has proposed a new explanation for the origin of supermassive black holes, suggesting that they are formed through the collapse of a massive seed black hole produced by the gravitational instability of a dark matter halo. This process, known as gravothermal collapse, can lead to the creation of a seed black hole w...

Ozone pollution has increased in Antarctica

Researchers analyzed 25 years of Antarctic data, finding that ozone levels near the ground have risen by up to 0.14 ppb per year, primarily driven by natural and human sources. This increase can have negative impacts on the region in the future due to ozone's ability to trap heat near Earth's surface.

How sex trafficking trauma affects the way its survivors parent

A study found that sex trafficking survivors' trauma affects their parenting, causing them to be overly protective and emotionally withdrawn. Despite this, they cope by finding meaning in motherhood and social support, and often experience strong connections with their children. The research highlights the need for policies and program...

Stem cells may hold a key to developing new vaccines against COVID-19

Researchers discovered a stem cell-mediated defense mechanism that reactivates dormant tuberculosis in mice infected with SARS-CoV-2, suggesting potential for new vaccines and avoiding global TB pandemic. This discovery may help develop novel therapeutic approaches against COVID-19 and target antiviral activities.

Heat spells doom for Aussie marsupials

Researchers from Australian National University warn that climate change may be causing more deaths among Australian marsupials, including the greater glider, due to heat-induced eating habits. The study highlights the importance of protecting food sources and restoring nutrient-rich forests to help these animals survive.
