And… it’s that time again. The clock stopped on the Nenana ice classic this afternoon (April 30, 12:50pm AT). This is pretty much on trend and unsurprising given the relatively slightly cool winter in Alaska. The jackpot on offer this year was $233,591 but will likely be shared among several winners. This year’s ‘break up’ is a little odd, since the ice moved sufficiently to trigger the clock, but not enough to actually topple the tripod (which is still visible as t

I’ve frequently discussed in recent years the mounting evidence for the need to lower the National Ambient Air Quality Standard for PM 2.5. There is also substantial evidence that PM exposure is an environmental justice issue. In this context, electrification of our transportation system is seen as having a substantial co-benefit in the reduction of vehicle-related PM emissions, particularly in EJ communities. .

The first three-dimensional map of the electromagnetic field that “clings” to the surface of a cube less than 200 nm across casts a fresh light on how materials dissipate heat at the nanoscale. The images, obtained by researchers in France and Austria, reveal the presence of infrared photon-like excitations known as surface phonon polaritons near the cube’s surface – a phenomenon that might be exploited to convey waste heat away from nanoelectronic components and so cool them down.

In today's industrial landscape, the pursuit of sustainable energy optimization and decarbonization has become paramount. Manufacturing corporations across the U.S. are facing the urgent need to align with decarbonization goals while enhancing efficiency and productivity. Unfortunately, the lack of comprehensive energy data poses a significant challenge for manufacturing managers striving to meet their targets.

Do not linger after using a public toilet is the advice from researchers at Florida Atlantic University (FAU), who have done a comprehensive study of how aerosols with the potential to carry disease are created and dispersed by flushing toilets and urinals. Siddhartha Verma and colleagues studied three scenarios – toilet flushing, covered toilet flushing and urinal flushing – in a medium-sized public restroom on the FAU campus.

Right: a shoot-through FLASH plan with four proton beams aimed at fictitious target boxes outside the patient’s head. (Courtesy: Phys. Med. Biol. 10.1088/1361-6560/abe55a). FLASH radiotherapy, in which therapeutic radiation is delivered at a very high dose rate, shows promise for sparing normal tissues while maintaining the tumour kill seen in conventional radiotherapy.
