Human influences have the potential to reduce the effectivity of communication in bees, adding further stress to struggling colonies, according to new analysis.

Scientists at the University of Bristol studying honeybees, bumblebees and stingless bees found that variations in communication strategies are explained by differences in the habitats that bees inhabit and differences in the social lifestyle such colony size and nesting habits.

The findings, published today in PNAS, reveal that anthropogenic changes, such as habitat conversion, climate change and the use of agrochemicals, are altering the world bees occupy, and it is becoming increasingly clearer that this affects communication both directly and indirectly; for example, by affecting food source availability, social interactions among nestmates and their cognitive functions.

😗😁 Very interesting findings around the olmec statues.

In a March 31 tweet confirming its recovery, Ebrard referred to the massive stone carving as “the Olmec piece most sought after by Mexico. … It’s about to return to its home, from where it should never have been stolen.”

Mexican officials found out earlier this year that the Manhattan District Attorney’s Antiquity Trafficking Unit had recovered the piece, which is roughly five feet wide, six feet tall and carved out of a slab of stone weighing nearly one ton.

The DA’s office formed the unit in 2017 to deal with the nonstop trade of stolen antiquities from historic sites around the globe. A 2021 article in The Atlantic referred to the unit as the “Tomb Raiders of the Upper East Side.”

“Generative” systems such as ChatGPT promise to generate rich profits for those who harness the technology’s potential — and is already minting fortunes for the sellers of the requisite picks and shovels.

A grey rectangular building on the outskirts of San Jose houses rows upon rows of blinking machines. Tangles of colourful wires connect high-end servers, networking gear and data-storage systems. Bulky air-conditioning units whirr overhead. The noise forces visitors to shout.

The building belongs to Equinix, a company that leases data-centre space.

The clock’s accuracy would be as high as one second for every 300 billion years.

A collaboration between researchers from various institutes in Germany has brought us a step closer to building the first-ever nuclear clock. In experiments carried out at the European Organization for Nuclear Research (CERN), the researchers measure the radiative decay of thorium-229 nuclear isomer, the first instance of having achieved this feat and a critical component for building nuclear clocks.

For years atomic clocks have been our standard of accuracy when it comes to clocks.

For years atomic clocks have been our standard of accuracy when it comes to clocks. The best optical atomic clocks have a precision rate of 10-18, which is equivalent to an inaccuracy of one second every 30 billion years.

If rising oceans aren’t worry enough, add this to the risks New York City faces: The metropolis is slowly sinking under the weight of its skyscrapers, homes, asphalt and humanity itself.

New research estimates the ’s landmass is sinking at an average rate of 1 to 2 millimeters per year, something referred to as “subsidence.”

That happens everywhere as ground is compressed, but the study published this month in the journal Earth’s Future sought to estimate how the massive weight of the city itself is hurrying things along.
