Having a fever. Having a fever?
Measuring the temperature of objects at a nanometer-scale has been a long challenge, especially in living biological samples, because of the lack of precise and reliable nanothermometers. An international team of researchers has realized a quantum technology to probe temperature on a nanometer-scale, and have observed a ‘fever’ in tiny nematode worms under pharmacological treatment.…

Certain!
Physicists are raising doubts about the existence of an exotic subatomic particle that failed to show up in twin experiments. (1) But by when would anyone be certain? When can anyone know anything? What a weird world. Shaped by the ones who are afraid of it. People being certain of what they know. Full of…

Rough.
Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that…

God. Angels. Particles. Lost.
A 2017 report of the discovery of a particular kind of Majorana fermion – the chiral Majorana fermion, referred to as the “angel particle” – is likely a false alarm, according to another research. Majorana fermions are enigmatic particles that act as their own antiparticle and were first hypothesized to exist in 1937. They are…

Measuring… (What?)
A new optical atomic clock makes ultra-precise time measurements. (1) Measuring time. Even though we are not certain what time is. You see, not knowing something does not hinder you from handling it. But this goes even further than that. Not knowing something is the sole pre-requisite of handling it. Because if you knew it,…
