Boiled bubbles jump to carry more heat
The topic of water and the way it can move producing water droplets that leap -- propelled by surface tension -- and frost that jumps -- by way of electrostatics -- is a central focus of a group of scientists. Having incorporated the two phases of liquid and solid in the first two volumes of their research, their third volume investigates a third phase, with boiling water.

1.5°C pathways can still be achieved, combining fairness and global climate protection
Global warming can still be limited to 1.5°C by 2100 while ensuring that the poor are not hit hardest by climate policies and climate impacts. This is achieved by immediately introducing broad carbon pricing together with re-distributive policies using carbon pricing revenues and further measures to reduce energy consumption, accelerate technological transitions, and transform the land sector.

New theory unites Einstein's gravity with quantum mechanics
The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a quantum theory of gravity, string theory and loop quantum gravity. But a new theory challenges that consensus and takes an alternative approach by suggesting that spacetime may be classical -- that is, not governed by quantum theory at all.

Quantum physics: Superconducting Nanowires Detect Single Protein Ions
An international research team has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% quantum efficiency and exceed the detection efficiency of conventional ion detectors at low energies by a factor of up to a 1,000. In contrast to conventional detectors, they can also distinguish macromolecules by their impact energy. This allows for more sensitive detection of proteins and it provides additional information in mass spectrometry.

Endovascular catheter opens blocked arteries deep within lungs
A new endovascular catheter, recently approved by the U.S. Food and Drug Administration (FDA), is paving the way to more effective and safe treatment for acute pulmonary embolism. Already shown to be effective for reducing blockages in lung arteries, new research shows that this catheter also reduces blockages in the smaller segmental pulmonary artery branches. These branches are ultimately responsible for oxygenating the blood in the lungs. The new study, which was part of the National Institutes of Health-sponsored multicenter RESCUE clinical trial, further showed a correlation between decreased numbers of blockages in the small lung arteries and functional recovery of the right ventricle of the heart, which pumps blood into the main pulmonary artery of the lungs. Compared to other devices, the BASHIR™ catheter also had significantly lower bleeding rates, a key advance in acute pulmonary embolism treatment. The findings are described in JACC: Advances.

The study's results include current and future extreme heat across very hot and dry, and very hot and humid conditions, with risks increasing over most of the world.
