From pacemakers to neurostimulators, implantable medical devices rely on batteries to keep the heart on beat and dampen pain. But batteries eventually run low and require invasive surgeries to replace. To address these challenges, researchers have devised an implantable battery that runs on oxygen in the body. The study shows in rats that the proof-of-concept design can deliver stable power and is compatible with the biological system. Read more ›

Researchers have discovered the first species pollinated by sap beetles in the genus Pandanus, a group of palm-like plants native to the tropics and subtropics of Africa and Eurasia. The discovery overturned the long-held belief that these plants were pollinated by wind. The researchers also found that fragrant screw pines' male and female flowers produced heat at night stably, making them the first such species in the family Pandanaceae. Read more ›

Rabbits are popular family pets, with around 1.5 million in the UK and it is important that owners can recognize when their animal is in pain, and know when to seek help to protect their rabbit's welfare. New research has found the majority of rabbit owners could list signs of pain and could mostly identify pain-free rabbits and those in severe pain, but many lacked knowledge of the subtler sign...

The queens in colonies of social insects, such as ants, bees, and wasps, are considered the veritable embodiment of specialization in the animal kingdom. The common perception is that the queen's only task is to lay eggs -- and that this attribute is an inherent trait, not influenced by external factors. In contrast, recent research has demonstrated that in certain ant colonies the social environment can play a crucial role... Read more ›

While CRISPR has shown immense promise as a next-generation therapeutic tool, the gene editing technology's edits are still imperfect. Researchers have developed a new system to test and analyze CRISPR-based DNA repair and related risks from unintended but harmful 'bystander' edits. Read more ›

Most organic household waste ends up in landfills where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming. A new study explores the effects of curbside compost collection programs. Read more ›

Researchers have discovered a protein called SEL1L that plays a critical role in clearing collagen from tissue, and which may be a therapeutic target to help prevent fibrosis, scar tissue that interferes with organ function. The paper provides clues that could lead to drug development for diseases like lung fibrosis which have no therapeutic options currently. Read more ›

Researchers have now developed standards and calibrations for optical microscopes that allow quantum dots to be aligned with the center of a photonic component to within an error of 10 to 20 nanometers (about one-thousandth the thickness of a sheet of paper). Such alignment is critical for chip-scale devices that employ the radiation emitted by quantum dots to store and transmit quantum information. Read more ›
