Alarm for apple and cherry trees in Trentino
In the Italian Val di Non valley, in Trentino, temperatures were below zero on the morning of 7 April 2021, marking -7 °C in the coldest areas and -4 °C in the middle valley. The drop in temperature was confirmed by the local producers Fabrizio Zadra and Matteo Dal Piaz. There is some worry, even if it s still early to assess the extent of the damage. On 7 April 2021, the temperature remained below zero until 9 am, which is a very long time. The phenological staging of apple trees is different depending on the areas and the variety. They range from the pink bud stage to open flowers, said Zadra from Sanzeno in Val di Non (Trento).

Bacterial nanopores open future of data storage
Bioengineers at EPFL have developed a nanopore-based system that can read data encoded into synthetic macromolecules with higher accuracy and resolution than similar methods on the market. The system is also potentially cheaper and longer-lasting, and overcomes limitations that prevent us from moving away from conventional data storage devices that are rapidly maxing out in capacity and endurance.
