Multifunctional metalens unlocks with light
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a flat optical component that is simultaneously a metalens, a microscope objective that can resolve details smaller ...
Why does a spinning egg stand up?
If a hard-boiled egg is spun fast enough on a table, it will slowly stand upright as it continues to spin. Although the spinning egg rises due to the force of friction between the egg and the table, the full explanation involves ...
Feeding wildlife can influence migration, spread of disease
Animal migration patterns are changing as humans alter the landscape, according to new research from the University of Georgia. Those changes can affect wildlife interactions with parasites-with potential impacts on public ...
Researchers bring the bling to improve implants
In a world first, Australian researchers have harnessed the power of diamonds in a breakthrough that could lead to radical improvements in the way human bodies accept biomedical implants.
Genetic study shows explosion of diversity in fish after end-Cretaceous mass extinction
A team of researchers from several institutions across the U.S. has found evidence suggesting that there was an explosion of diversity in fish after the end-Cretaceous mass extinction. In their paper published in the journal ...
Warm Arctic means colder, snowier winters in northeastern US, study says
Scientists from Rutgers University-New Brunswick and Atmospheric and Environmental Research (AER) have linked the frequency of extreme winter weather in the United States to Arctic temperatures.
Pterosaurs went out with a bang, not a whimper
Fossils of six new species of pterosaurs - giant flying reptiles that flew over the heads of the dinosaurs - have been discovered by a research team led by the Milner Centre for Evolution at the University of Bath, revealing ...
It's not only size, but scales that matter in some male moth antennae
Male moths have evolved intricate scale arrangements on their antennae to enhance detection of female sex pheromones, which allows them to keep their antennae small enough to maximise flying, new research suggests.
Scientists help solve mystery of why comets emit X-rays
The mystery of why comets travelling through Space give off X-ray emissions has been solved thanks to new research undertaken by a team that included science staff from STFC's Central Laser Facility (CLF) and RAL Space.
Compassion helped Neanderthals to survive, new study reveals
They have an unwarranted image as brutish and uncaring, but new research has revealed just how knowledgeable and effective Neanderthal healthcare was.
World's largest cities depend on evaporated water from surrounding lands
Urbanization has taken billions of people from the rural countryside to urban centers, adding pressure to existing water resources. Many cities rely on renewable freshwater regularly refilled by precipitation, rather than ...
Ultra-white coating modelled on beetle scales
Researchers have developed a super-thin, non-toxic, lightweight, edible ultra-white coating that could be used to make brighter paints and coatings, for use in the cosmetic, food or pharmaceutical industries.
Infected 'zombie ants' face no discrimination from nest mates
Carpenter ants infected with a specialized parasitic fungus are not subjected to aggression or isolation from their nest mates, and they continue to share in the colony's food resources until they leave the nest for the last ...
The early bird got to fly: Archaeopteryx was an active flyer
The question of whether the Late Jurassic dino-bird Archaeopteryx was an elaborately feathered ground dweller, a glider, or an active flyer has fascinated palaeontologists for decades. Valuable new information obtained with ...
Google guru Page tests flying taxis in New Zealand (Update)
Pilot-less flying taxis are being tested in New Zealand as part of a project backed by Google co-founder Larry Page that supporters say will revolutionise personal transport.
Shaken, and stirred: Scaling up bioreactors' fluid dynamics
Bioreactors are widely used to produce different therapeutics in the biopharmaceutical and regenerative medicine industries. Drug development relies on small multi-well plates shaken around an orbital diameter, while production-scale ...
Researchers develop spectroscopic thermometer for nanomaterials
A scientific team led by the Department of Energy's Oak Ridge National Laboratory has found a new way to take the local temperature of a material from an area about a billionth of a meter wide, or approximately 100,000 times ...
Biophysicists discover how small populations of bacteria survive treatment
Small populations of pathogenic bacteria may be harder to kill off than larger populations because they respond differently to antibiotics, a new study by Emory University finds.
