(1) At some point we might even recreate the old recipes. But we will never be with those people eating.…

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.…

Zachariah Reagh, assistant professor of psychological and brain sciences in Arts & Sciences at Washington University in St. Louis found that brain activity in older adults isn’t necessarily quieter when it comes to memory. “It’s just different,” he said. What he found out is that while a 20-year-old notes all details in a movie, an…

Smell… Understand… Know…
A pair of researchers has used machine learning to understand what a chemical smells like – a research breakthrough with potential applications in the food flavor and fragrance industries. (1) But how can you understand smell without smelling something? How can you understand anything without knowing it first? Why would you seek knowledge about something…

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…
