Being mobile individually, at any time -- without owning a car: To facilitate this, public transportation authorities cooperate with service providers for new forms of mobility such as bicycle sharing, car sharing, or ridepooling. Researchers have studied how publicly available mobility options in the Karlsruhe region in the future can...
Air pollution linked to deadly heart rhythm disorder
Life-threatening arrhythmias are more common on days with highly polluted air, according to new research.
Researchers have developed a potential super wheat for salty soils
Researchers have developed several new varieties of wheat that tolerate soils with higher salt concentrations. After having mutated a wheat variety from Bangladesh, they now have a wheat with seeds that weigh three times more and that germinate almost twice as often as the original variety.
Noisy jackdaw birds reach ‘consensus’ before taking off
On cold, dark winter mornings, small black crows known as jackdaws can be heard calling loudly to one another from their winter roosting spots in the U.K. before taking off simultaneously right around sunrise. Now, researchers who've studied their daily activities in unprecedented detail report evidence that these groups of...
Skydiving salamanders live in world’s tallest trees
Researchers have documented in a vertical wind tunnel the amazing ability of one species of salamander -- which spends its entire life in the tops of redwoods -- to parachute, glide and maneuver in mid-air. Ground-dwellers, on the other hand, freak out during free-fall. The salamander's skydiving skills are likely...
Gene-edited tomatoes could be a new source of vitamin D
Tomatoes gene-edited to produce vitamin D, the sunshine vitamin, could be a simple and sustainable innovation to address a global health problem.
Turning X chromosome ‘off and on again’ critical for oocyte development
Researchers have found that a carefully orchestrated act of X-chromosome 'yoyo' predicts the successful and efficient development of mammalian egg cells. The findings could pave the way for generating artificial oocytes in the laboratory, helping researchers study the causes and treatments of infertility disorders and test the impact of drugs...
Multiple habitats need protecting to save UK bumblebees, finds 10-year citizen science study
A study using 10 years of citizen science data has found that a variety of targeted conservation approaches are needed to protect UK bumblebee species.
Organic farming or flower strips: Which is better for bees?
How effective environmental measures in agriculture are for biodiversity and wild bee populations depends on various factors and your perspective. This is shown by agroecologists. The research team found that when assessing the effectiveness of different measures, whether in the field (organic farming) or next to the field (flower strips...
Where do ‘Hawaiian box jellies’ come from?
An insightful cross-disciplinary team, working for over a decade, published a study recently revealing that a key number of hours of darkness during the lunar cycle triggers mature 'Hawaiian box jellyfish' (Alatina alata) to swim to leeward O'ahu shores to spawn.
