Bringing aromas indoors with the help of chemical products -- yes, air fresheners, wax melts, floor cleaners, deodorants and others -- rapidly fills the air with nanoscale particles that are small enough to get deep into your lungs, engineers have found over a series of studies.
Near-complete skull discovery reveals ‘top apex’, leopard-sized ‘fearsome’ carnivore
A rare discovery of a nearly complete skull in the Egyptian desert has led scientists to the 'dream' revelation of a new 30-million-year-old species of the ancient apex predatory carnivore, Hyaenodonta.
Does planetary evolution favor human-like life? Study ups odds we’re not alone
Humanity may not be extraordinary but rather the natural evolutionary outcome for our planet and likely others, according to a new model for how intelligent life developed on Earth.
Marine mystery solved: How anemonefish avoid stings from their sea anemone hosts
The clownfish-anemone living arrangement is one of the most widely recognized examples of symbiosis. Researchers have made a breakthrough in understanding how anemonefish can live safely among sea anemones without being stung by their venomous tentacles, solving a century-long mystery. Scientists have discovered that anemonefish have evolved to maintain very...
Under-sea mountains are key ‘hubs’ for sharks
Under-sea mountains are key locations for predators -- with 41 times more sharks than the open ocean, new research shows.
Brake pad emissions can be more toxic than diesel exhaust
A study has found microscopic particles emitted from certain types of commonly fitted brake pads can be more toxic than those found in diesel vehicle exhaust.
Mouse study finds impaired cell development: Intermittent fasting could be unsafe for teenagers
A recent study reveals that age plays a significant role in the outcomes of intermittent fasting. Researchers discovered that chronic intermittent fasting disrupted the development of insulin-producing beta cells in young mice. The findings raise concerns about potential risks for humans, especially teenagers.
Dessert stomach emerges in the brain
Who hasn't been there? The big meal is over, you're full, but the craving for sweets remains. Researchers have now discovered that what we call the 'dessert stomach' is rooted in the brain. The same nerve cells that make us feel full after a meal are also responsible for our...
Scientists herald active matter breakthrough with creation of three-dimensional ‘synthetic worms’
Researchers have made a breakthrough in the development of 'life-like' synthetic materials which are able to move by themselves like worms. Scientists have been investigating a new class of materials called 'active matter', which could be used for various applications from drug delivery to self-healing materials.
Models show intensifying wildfires in a warming world due to changes in vegetation and humidity; only a minor role for lightning
Climate scientists present a realistic supercomputer simulation that resolves the complex interactions between fire, vegetation, smoke and the atmosphere. The authors find that increasing greenhouse gas emissions will likely increase the global lightning frequency by about 1.6% per degree Celsius global warming, with regional hotspots in the eastern United States,...
