Global analysis on pollinators in cities: Wild bees and butterflies are at particular risk      (via sciencedaily.com)     Original source 

Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been impacted by this because honeybees, for example, can compensate for the reduction of urban pollinators. The study is the first comprehensive analysis of the subject and includes data from 133 studies. The results underline the importance of nature conservation measures in urban areas.

When soft spheres make porous media stiffer      (via sciencedaily.com)     Original source 

Porous media such as concrete physically represent a spherical packing of different components -- in this case cement, rock and water. The mechanical properties of such mixtures are still difficult to calculate due to their discretized nature. A team has now been able to investigate an unexpected property of mixtures of granular media consisting of soft and stiff spherical particles. For this purpose, a combination of ultrasound investigations and X-ray computed tomographic imaging was employed, allowing a three-dimensional (3D) characterization and evaluation. The discovery could contribute to safer future building in earthquake zones.

Potential financial losses from a renewable energy transition are concentrated among the wealthy      (via sciencedaily.com)     Original source 

One common rationale against climate action is that the resulting fossil fuel investment losses could impact people's retirement or long-term savings. However, researchers report that the loss of fossil fuel assets would have a minimal impact on the general populace. In high-income countries, most financial losses would be borne by the most affluent individuals for whom the loss makes up a small percentage of their total wealth. In contrast, the financial loss of lower-income individuals would be minimal and feasible for governments to compensate.

Never-before-seen way to annihilate a star      (via sciencedaily.com)     Original source 

Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.

Conservation policies risk damaging global biodiversity, researchers argue      (via sciencedaily.com)     Original source 

Rewilding, organic farming and the 'nature friendly farming' measures included in some government conservation policies risk worsening the global biodiversity crisis by reducing how much food is produced in a region, driving up food imports and increasing environmental damage overseas.

Cave excavation pushes back the clock on early human migration to Laos      (via sciencedaily.com)     Original source 

Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.
