In the movie “A Fish Called Wanda”, the villain Otto effortlessly gobbles up all the occupants of Ken`s fish tank. Reality, however, is more daunting. At least one unfortunate fan who re-enacted this scene was hospitalized with a fish stuck in the throat. At the same time this also was a painful lesson in ichthyology…
A study published the week of July 5 in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates. “Our study shows that the wing pigmentation of dragonfly males evolves so consistently…
Research published today has demonstrated the viability of 3D-printed tissue scaffolds that harmlessly degrade while promoting tissue regeneration following implantation. The scaffolds showed highly promising tissue-healing performance, including the ability to support cell migration, the ‘ingrowth’ of tissues, and revascularisation (blood vessel growth). Professor Andrew Dove, from the University of Birmingham’s School of Chemistry, led…
Researchers at Uppsala University have discovered lymph node-like structures close to the tumour in brain cancer patients, where immune cells can be activated to attack the tumour. They also found that immunotherapy enhanced the formation of these structures in a mouse model. This discovery suggests new opportunities to regulate the anti-tumour response of the immune…
Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape – creating potential neurological impacts that could be both positive and negative, a new study reveals. Scientists found that metal-based nanomaterials such as silver and zinc oxide…
The theory that modern society is too clean, leading to defective immune systems in children, should be swept under the carpet, according to a new study by researchers at UCL and the London School of Hygiene & Tropical Medicine. In medicine, the ‘hygiene hypothesis’ states that early childhood exposure to particular microorganisms protects against allergic…
DIRT TOWN VALLEY, Ga. — Just before people started to take the pandemic seriously, Stacie Marshall slipped into the back of a conference room in Athens, Ga., and joined two dozen Black farmers in a marketing seminar called “Collards Aren’t the New Kale.” She stood out, and not just because she was one of only…
When it came to coronavirus vaccination, the third time was the charm for Esther Jones, a dialysis nurse in rural Oregon. After two doses of the Pfizer-BioNTech vaccine failed to jolt her immune system into producing antibodies, she sought out a third, this time the Moderna shot. It worked. Blood tests revealed a reasonable antibody…
Tyson Foods is recalling nearly 8.5 million pounds of frozen chicken that may have been contaminated with listeria, the Agriculture Department said. The voluntary recall was issued after Agriculture Department investigators were notified last month about two people who had been sickened with listeriosis, the department said in a statement on Saturday. An investigation found…
Para algunos de nosotros, la era del rapidín ha terminado. Sin embargo, una excursión en solitario a mediodía o un encuentro para uno a la hora del té podría ser genial. Sin importar el lugar, los juguetes también son para los grandes. Cuando las personas menosprecian a las tiendas eróticas, a menudo lo hacen con…
