Shocking heat waves stabilize single atoms

Researchers at Argonne National Laboratory successfully stabilized single atoms using record-high temperatures of up to 2000 K. The method enables the creation of stable single atom catalysts, which can remain in their place for unprecedented periods of time, maximizing atom-use efficiency and improving catalytic performance.

How neuronal recognition of songbird calls unfolds over time

Scientists have created a novel approach to analyze neuronal response to different call meanings in songbirds. The analysis shows that initial responses contain information about the call's meaning, with additional information accumulating up to 600 milliseconds. Individual neurons play a significant role in categorizing call meanings.

The secret of motivation

Researchers identified a neural circuit in fruit flies that controls perseverance, with dopamine and octopamine neurotransmitters playing a key role. The finding suggests that simple organisms like fruit flies exhibit stamina and perseverance, challenging the idea that these traits are unique to humans.

Chemists clarify a chiral conundrum?

Rice chemists disentangled the mysterious interactions between bovine serum albumin and gold nanorods, revealing multilevel chirality and a possible way to sense single proteins' handedness. This discovery could lead to the development of drug-sensing tools with improved accuracy.

NIST goes with the (slow) flow: New technique could improve biotech, precision medicine

Researchers at NIST have created an optical system that can measure the flow of extremely small amounts of liquids with high accuracy. The technique relies on a laser interacting with light-sensitive molecules in a liquid flowing through a microchannel, allowing for precise control of flow rates as low as 2 nanoliters per minute.

Teenage acne may be a natural, transient inflammatory state

Researchers propose that teenage acne is a naturally occurring, inflammatory state caused by the sudden change in skin microbiota composition and increased sebum production during adolescence. This hypothesis challenges conventional thinking and may explain special clinical characteristics of acne.
