| COVID-19 infection detected in deer in six Ohio locations Posted: 23 Dec 2021 08:32 AM PST Scientists have detected infection by at least three variants of the virus that causes COVID-19 in free-ranging white-tailed deer in six northeast Ohio locations, the research team has reported. |
| Researchers lay groundwork for potential dog-allergy vaccine Posted: 22 Dec 2021 12:32 PM PST Scientists have identified a series of molecular candidates for those parts of dog allergens that cause immune reactions in people--the first step in developing a vaccine against most causes of dog allergies. |
| How tissues form complex shapes that enable organ function Posted: 22 Dec 2021 12:31 PM PST From the smooth tubes of our arteries and veins to the textured pockets of our internal organs, our bodies are made of tissues arranged in complex shapes that aid in performing specific functions. |
| Geneticists’ new research on ancient Britain contains insights on language, ancestry, kinship, milk Posted: 22 Dec 2021 12:31 PM PST New research revealing a major migration to the island of Great Britain offers fresh insights into the languages spoken at the time, the ancestry of present-day England and Wales, and even ancient habits of dairy consumption. |
| Humble lizards offer surprising approach to engineering artificial lungs Posted: 22 Dec 2021 12:29 PM PST A new study shows how the brown anole lizard solves one of nature's most complex problems -- breathing -- with ultimate simplicity. Whereas human lungs develop over months and years into baroque tree-like structures, the anole lung develops in just a few days into crude lobes covered with bulbous protuberances. These gourd-like structures, while far less refined, allow the lizard to exchange oxygen for waste gases just as human lungs do. And because they grow quickly by leveraging simple mechanical processes, anole lungs provide new inspiration for engineers designing advanced biotechnologies. |
| Developing bioactive coatings for better orthopaedic implants Posted: 22 Dec 2021 05:40 AM PST Bioactive coatings play a vital role in the success of implants such as those for knees or hips, because their properties induce a biological response that is good for the health. Researchers are working on a coating that mimics bone tissue. |
| Study finds electric vehicles provide lower carbon emissions through additional channels Posted: 21 Dec 2021 06:25 PM PST A recent study found that the total indirect emissions from the supply of chain of electric vehicles pale in comparison to the same indirect emissions from fossil fuel-powered vehicles. |
| Form, function and a deadly fungus Posted: 21 Dec 2021 10:35 AM PST New research marks a major step forward in understanding C. auris biology, homing in on the genetics behind its ability to shape-shift from a round yeast form to a more hair-like, filamentous form -- potentially unlocking how the emerging pathogen causes disease. |
| Your seat on public transportation determines level of exposure to exhaled droplets, study finds Posted: 21 Dec 2021 10:35 AM PST In a new study, researchers developed a model with an unprecedented level of detail and focused on conditions that are more characteristic of asymptomatic transmission. The multiphysics model involved air and droplet dynamics, heat transfer, evaporation, humidity, and effects of ventilation systems. The researchers modeled various scenarios in close detail and were able to reconstruct their ventilation paths. |
| Posted: 21 Dec 2021 10:34 AM PST As the Arctic and the oceans warm due to climate change, understanding how a rapidly changing environment may affect birds making annual journeys between the Arctic and the high seas is vital to international conservation efforts. However, for some Arctic species, there are still many unknowns about their migration routes. Using telemetry to solve some mysteries of three related seabird species -- the pomarine jaeger, parasitic jaeger and long-tailed jaeger -- scientists discovered they took different paths across four oceans from a shared central Canadian high Arctic nesting location. |
| Promising new target for tuberculosis treatment Posted: 21 Dec 2021 10:31 AM PST Mycobacterium tuberculosis (Mtb), the hardy bacterial species that causes tuberculosis (TB), has an unexpected vulnerability that future drugs may be able to exploit, according to a new study. |
| Posted: 21 Dec 2021 07:27 AM PST A new study tracks the development of early humans' hunting practices over the last 1.5 million years -- as reflected in the animals they hunted and consumed. The researchers claim that at any given time early humans preferred to hunt the largest animals available in their surroundings, which provided the greatest quantities of food in return for a unit of effort. |
