Want to save the bees? Pay attention to pathogens and flowers

New research conclusively shows that certain physical traits of flowers affect the health of bumble bees by modulating the transmission of a harmful pathogen called Crithidia bombi. In particular, the research shows that the length of a flower's corolla, or the flower's petals, affects how this pathogen gets transferred between bees because shorter corollas mean that fewer bee feces wind up inside...
Mathematicians explain how some fireflies flash in sync

A new study by mathematicians shows that math borrowed from neuroscience can describe how swarms of these unique insects coordinate their light show, capturing key details about how they behave in the wild.

A large-scale comparison of direct oral anticoagulants (blood thinners), commonly prescribed for irregular heartbeats, has identified the drug with the lowest risk of bleeding.
Ancient genomes reveal hidden history of human adaptation

The use of ancient DNA, including samples of human remains around 45,000 years old, has shed light on a previously unknown aspect of human evolution.
Violent supershear earthquakes are more common than previously thought
- ScienceDaily
- 22/11/1 02:28
About 14% of magnitude 6.7 or greater strike-slip earthquakes since 2000 have been supershear. That's 50% more than previously thought. Supershear earthquakes occur when a fault ruptures faster than seismic shear waves can travel through rock. The events were thought to be rare because scientists had mostly looked for them on land. The findings suggest that disaster planning assessments should...
New species of owl discovered in the rainforests of Africa's Príncipe Island
A new species of owl has just been described from Príncipe Island, part of the Democratic Republic of São Tomé and Príncipe in Central Africa. Scientists were first able to confirm its presence in 2016, although suspicions of its occurrence gained traction back in 1998, and testimonies from local people suggesting its existence could be traced back as far as 1928.
Antibody weapon against malaria shows promise in Africa
A new way to prevent malaria that showed promise in 9 U.S. volunteers deliberately exposed to parasite-laden mosquitoes last year has now shown its mettle in a real-world situation in Africa. A study published today in the
New England Journal of Medicine
showed that
a single dose
of lab-produced monoclonal antibodies can protect recipients from infection...
Catholic Church can reduce carbon emissions by returning to meat-free Fridays, study suggests
In 2011, the Catholic bishops of England and Wales called on congregations to return to foregoing meat on Fridays. Only around a quarter of Catholics changed their dietary habits—yet this has still saved over 55,000 tons of carbon a year, according to a new study led by the University of Cambridge.
