Some Protective Resin Coatings May Damage Metal Artifacts

American Chemical Society (ACS) — Wed, 23 Apr 2025 08:00:00 EST

Conservators and museum technicians use clear coatings to protect archaeological metal objects, preserving their detailed views. However, some resins in these coatings react with iron-containing metals, causing damage.

How Sebastien Sauve Turned 'Forever Chemicals' Into Big News

Universite de Montreal — Tue, 22 Apr 2025 12:00:43 EST

If Quebecers are now aware of the health risks of per- and polyfluoroalkyl substances (PFAS), it's largely thanks to the work of UdeM's muckraking environmental chemistry professor.

A light-activated probe reveals TB immune system evasion mechanisms

American Chemical Society (ACS) — Mon, 21 Apr 2025 10:55:05 EST

The pathogen that causes tuberculosis is deadly in part because of its complex outer envelope, which helps it evade immune responses of infected hosts. In an ACS Infectious Diseases paper, researchers developed a chemical probe to study a key component of this envelope. Their results provide a step toward finding new ways of inactivating the bacterium.

Simulations Predict How Pesticides May Affect Honeybee Colonies

American Chemical Society (ACS) — Mon, 21 Apr 2025 10:55:03 EST

Researchers in ACS' Environmental Science & Technology demonstrate that an artificial intelligence (AI)-based monitoring system combined with a computer model can link the exposure of neonicotinoid pesticides on individual honeybees to the health of the whole colony.

Scientists Identify Agent of Transformation In Protein Blobs That Morph From Liquid to Solid

Rutgers University-New Brunswick — Fri, 18 Apr 2025 15:00:00 EST

An international research collaboration led by Rutgers University-New Brunswick scientists that examined microscopic blobs of protein found in human cells has discovered that some morph from an almost honey-like substance to a hard candy-like solid. These mysterious droplets, known as biomolecular condensates, solidify when they carry a high proportion of the protein alpha-synuclein, the scientists reported in Science Advances. Clumps of alpha-synuclein are commonly found in the brain cells of people with Parkinson's disease, a neurodegenerative brain disorder.

???Un paso hacia el aprovechamiento de la energia limpia del agua de lluvia

American Chemical Society (ACS) — Wed, 16 Apr 2025 21:15:33 EST

Cuando dos materiales se tocan, sus cargas superficiales se alteran, generando electricidad estatica. Investigadores han aprovechado este fenomeno para generar electricidad a partir de gotas de agua que se desplazan por un tubo, produciendo suficiente energia para encender 12 LED.

John C. Gordon Elected International Fellow of the Royal Society of Edinburgh

Brookhaven National Laboratory — Wed, 16 Apr 2025 09:25:06 EST

John C. Gordon, chair of the Chemistry Division at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, was elected to the Royal Society of Edinburgh (RSE), Scotland's National Academy of science and letters, as an International Fellow.

A Step Toward Harnessing Clean Energy From Falling Rainwater

American Chemical Society (ACS) — Wed, 16 Apr 2025 08:00:00 EST

Water flowing over some surfaces can gain or lose charge. Now, researchers reporting in ACS Central Science have harnessed the phenomenon to generate electricity from rain-like droplets moving through a tube. They demonstrate a new kind of flow that makes enough power to light 12 LEDs.

Imagine editing the bacteria in your gut the same way scientists edit DNA, targeted, precise, and powerful. That's exactly what Dr. Carlotta Ronda, a Principal Investigator at the Innovative Genomics Institute at the University of California, Berkeley, is working on.

Scientists Develop Process Using Molecules in the Cell to Identify Environmental Signals

Rutgers University-New Brunswick — Thu, 10 Apr 2025 20:10:31 EST

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health. Research by Rutgers University-New Brunswick scientists centers on RNA, a nucleic acid that plays a crucial role in most cellular processes. Their work is expected to have applications in the surveillance of environmental chemicals and, ultimately, the diagnosis of critical diseases including neurological and cardiovascular diseases and cancer.

New PCR Chip Design: High-Pressure Liquid Seal Solves Bubble Problem

Chinese Academy of Sciences — Wed, 09 Apr 2025 09:25:40 EST

A new discovery has reshaped our understanding of PCR chip technology: water vapor, not air expansion, is the primary culprit behind bubble formation in polydimethylsiloxane (PDMS)-based chips. This revelation has led to the development of a high-pressure liquid seal technique that effectively eliminates bubbles and prevents water loss during the polymerase chain reaction (PCR) process.
