PEPPI-MS protocols reveal chemical structure of cellular proteins on a large scale

Sciencedaily.com 

Researchers have detailed PEPPI-MS, an experimental protocol combining high-resolution protein fractionation using SDS-polyacrylamide gel electrophoresis (SDS-PAGE) with the latest mass spectrometry technology to enable highly sensitive analysis of proteoforms, the diverse chemical structures of proteins. This protocol paper is expected to contribute to the development of disease diagnostics based on proteoform information.

Nerve stimulation: The brain is not always listening

Various diseases can be treated by stimulating the vagus nerve in the ear with electrical signals. However, this technique does not always work. A study has now shown: The electrical signals must be synchronized with the body's natural rhythms -- heartbeat and breathing.

Biologists have identified important components and mechanisms of the molecular machinery that transmits information about a pathogen encounter within the plant organism.

Unraveling the connection between Canadian wildfires and Arctic ice clouds

Sciencedaily.com 

Ice nucleating particles as a kind of aerosols have a significant impact on the Arctic climate by promoting the formation of ice clouds at a temperature above -- 38 degrees Celsius. Wildfires in mid-latitudinal areas are a major source of these aerosols. However, a direct observation of wildfire-emitted aerosols facilitating ice cloud formation has never been documented. Now, using field and climate data, scientists have linked aerosols emitted by Canadian wildfires in 2023 to the formation of ice clouds over the Arctic Ocean.

Progress toward a new generation of rechargeable batteries

Sciencedaily.com 

Lithium-air batteries have the potential to outstrip conventional lithium-ion batteries by storing significantly more energy at the same weight. However, their high-performance values have thus far remained theoretical, and their lifespan remains too short. A team has now proposed addition of a soluble catalyst to the electrolyte. It acts as a redox mediator that facilitates charge transport and counteracts passivation of the electrodes.

DoT seeks 'Time-Bound' switch by telcos to authorisation rule

Economictimes.indiatimes.com 

The Department of Telecommunications (DoT) plans to transition all telecom license holders to an authorization-based regime under the Telecommunications Act, 2023, to eliminate dual frameworks and avoid litigation. The new regime, recommended by TRAI and approved by the Digital Communications Commission, replaces the current licensing system with an authorization mechanism where terms are notified separately.
