Air conditioners require a lot of energy and can leak greenhouse gases. Today, scientists report an eco-friendly alternative — a plant-based cooling film with many textures and iridescent colors that could someday keep buildings and cars cool. They will present their results at ACS Spring 2023.
Many highly sensitive diagnostic tests for viral diseases still require complicated techniques. But now, a team reporting in ACS Central Science has developed a sensitive method that analyzes viral nucleic acids quickly and can be completed in one step with “glow-in-the-dark” proteins.
Add water to ouzo liquor, and it turns cloudy. This “ouzo effect” is an example of an easy way to make highly stable emulsions but nobody has yet fully understood how it works. Now, researchers report in ACS Central Science that the secret may lie in the unique structure of the emulsion’s droplets.
Sewage can provide information on potentially harmful compounds, such as per- and polyfluoroalkyl substances (PFAS), that get released into the environment. Now, researchers in Environmental Science & Technology Letters report an unexpected source of these substances in wastewater — toilet paper.
A new technique that targets and breaks apart certain proteins — rather than just interfering with them — may offer a pathway toward treatment of Alzheimer's disease. Researchers reporting in ACS Central Science have designed a compound that breaks down a protein closely associated with the disease.
A compound found in cigarette and industrial smoke, benzo(a)pyrene (BaP), is known to damage DNA. Now, researchers reporting in ACS Central Science have mapped these effects for the first time in human lung cells after BaP exposure, which could help predict exposures that lead to cancers.
Researchers reporting in ACS Infectious Diseases have developed a procedure that could help researchers catch up to microbes which can rapidly mutate and evade detection and treatment. Their “AutoPLP” technique designs nucleic acid probes to detect new variants quickly, accurately and easily.
Spike proteins are one of the main targets for COVID-19 vaccines and treatments. But those remedies gradually lose effectiveness when the spike proteins mutate. Now, researchers report in ACS Central Science that they have discovered small molecules that target other segments that mutate less.
Devices currently in development that clean up dirty water using sunlight can only produce a few gallons of water each day. But now, researchers in ACS Central Science report how a sunlight-powered porous hydrogel could potentially purify enough water to meet daily needs — even when it’s cloudy.
Only a few forms of cancer can currently be diagnosed using blood samples. Now, researchers reporting in ACS Sensors have developed an easy-to-use method that can detect small amounts of cancer-related molecules in exosomes in plasma and effectively distinguish between malignant and benign samples.
Smart voice assistants could make the laboratory safer for scientists and technicians who handle infectious samples. Researchers in ACS Sensors now report a small, voice-activated device that can extract and pretreat bacterial DNA, helping protect those on the front lines of disease outbreaks.
Journalists who register for the spring meeting of the American Chemical Society (ACS) will have access to more than 10,000 presentations on topics. ACS Spring 2023 is a hybrid meeting being held virtually and in-person in Indianapolis on March 26-30 with the theme “Crossroads of Chemistry.”
The way that silkworms wind their cocoons is now helping scientists more easily make new biomedical materials. Researchers in ACS’ Nano Letters have mimicked the seemingly simple head bobbing of silkworms to create more consistent micro- and nanofibers with less equipment than other approaches.
Plants can detect blue light, but instead of causing sleepless nights, it could help make their fruits taste better. Researchers now report in ACS’ Journal of Agricultural and Food Chemistry that mangoes can become redder, sweeter and more ripe when exposed to blue light over several days.
By collecting electrons naturally transported within plant cells, scientists can generate electricity. Now, researchers reporting in ACS Applied Materials & Interfaces have, for the first time, used a succulent plant to create a living “bio-solar cell” that runs on photosynthesis.
One hypothesis about how life began on earth is that meteorites delivered amino acids—life’s building blocks—to our planet. Now, researchers reporting in ACS Central Science have experimentally shown that amino acids could have formed in these early meteorites from reactions driven by gamma rays.
On their own, microplastics are potentially harmful, and it’s unclear what effect they could have on pollutants. Now, researchers reporting in ACS’ Environmental Science & Technology Letters show that, when attached to microplastics, UV filters in sunscreens can make chromium metal more toxic.
Researchers in ACS Nano report a kaleidoscope-like film for telling different sweeteners apart that displayed multiple colors when stretched by hand. When evenly stretched with a simple apparatus, the material enhanced the unique shifts in fluorescence intensity of 14 sugars tagged with a dye.
Researchers in ACS Central Science report that artificial intelligence (AI) could speed up the development of promising water filtration materials. In a proof-of-concept study, they simulated different patterns of water-attracting and water-repelling groups and found optimal arrangements.
The American Chemical Society (ACS) Board of Directors has selected Albert G. Horvath, Treasurer and Chief Financial Officer (CFO) at ACS, as the Society’s next CEO, effective Jan. 1, 2023. He succeeds Thomas Connelly Jr., who is retiring after nearly eight years with ACS.
Researchers are working to harness otherwise wasted static electricity with triboelectric nanogenerators (TENGs). Now, in ACS Omega, a team describes an easy way to manufacture these tiny generators out of double-sided tape that pack in higher energy densities than previously reported versions.
microRNAs are thought to suppress protein expression in dividing cells, such as tumor cells. But new research in ACS Central Science shows that some of these molecules can elevate the expression of a particular gene in dividing human cells and in cancer cells, challenging conventional wisdom.
Recent studies have led to the development of imaging and spinal fluid tests for patients with Alzheimer's disease. However, the tests can only monitor severe disease. Reporting in ACS Chemical Neuroscience, researchers have now identified a biomarker that could help physicians diagnose AD earlier.
Demand is growing for technologies to cool buildings. Now, researchers report in ACS Energy Letters that they have used advanced computing technology and artificial intelligence to design a transparent window coating that could lower the temperature inside buildings, without expending energy.
Hydrogen gas could someday replace fossil fuels as a “clean” energy source, producing only water and energy. Now, researchers reporting in ACS Central Science have developed a method to store and release highly pure hydrogen with salts in the presence of amino acids.
Researchers reporting in ACS Sensors have designed a food-grade device from edible materials that lets you know if food has been thawed and refrozen . The proof-of-concept sensor provides a color readout when it’s warmed above a specific temperature, which is tunable from -58 F to 32 F.
On behalf of the American Chemical Society (ACS), President Angela K. Wilson, Ph.D., congratulates today’s winners of the Nobel Prize in Chemistry: Carolyn R. Bertozzi, Ph.D., Stanford University; Morten Meldal, Ph.D., University of Copenhagen; and K. Barry Sharpless, Ph.D., Scripps Research.
To assist with coverage of the 2022 Nobel Prize in Chemistry, the American Chemical Society (ACS) will issue a statement from ACS President Angela K. Wilson, Ph.D., after the official announcement is made on Wednesday, Oct. 5. Wilson will be available for interviews beginning at 6:15 a.m. ET.
The oils in fingerprints degrade over time, and it’s difficult to figure out their age. Now, researchers reporting in ACS Central Science have discovered molecular markers for changes to these oils over a seven-day time period — which could be used to estimate fingerprints’ ages more accurately.
Though well-known as a respiratory illness, COVID-19 can also affect the nervous system. Now, researchers reporting in ACS Infectious Diseases have developed a new tool and possible vaccine candidate that could help scientists understand how SARS-CoV-2 could be invading these cells.
Adding an ingredient called an adjuvant can help vaccines elicit a more robust immune response. In a study in ACS Infectious Diseases, researchers report a substance that boosted the immune response to an experimental COVID-19 shot in mice by 25 times, compared to injection with the vaccine alone.
Media Briefing Schedule for ACS Fall 2022
Mealworms are edible insects and a healthful alternative to traditional meat protein. Today, researchers report that they’ve cooked up mealworms with sugar, creating a “meat-like” flavoring for a tasty source of extra protein in convenience foods. They will present their results at ACS Fall 2022.
Tattoo inks are unregulated in the U.S. A team has analyzed what is in some inks, and it doesn’t always match what’s on ingredient labels. Once the study is complete, they will publish their results on a website for consumers and tattoo artists. They will present their results at ACS Fall 2022.
Plant-based milk alternatives are an attractive option for many people. But some minerals are required to be on the Nutrition Facts label only under certain circumstances. Now, researchers have analyzed plant-based beverages and report variability in mineral content. They will present their results at ACS Fall 2022.
Vanilla is one of the most popular spices. Today, scientists report a profile of 20 chemicals found in vanilla bean extracts, including several previously unknown ones. The work could help producers develop better-tasting vanilla. The researchers will present their results today at ACS Fall 2022.
Nanoplastics often find their way into the soil and water. But they can also float in the air. Now, researchers have developed a sensor that detects airborne nanoplastics and reports their type of plastic and sizes using carbon dot films. They will present their results at ACS Fall 2022.
Instead of crafting wooden objects with a saw or chisel, scientists can now program a 3D printer to extrude flat wooden shapes that self-morph into complex, 3D shapes as they dry. Potential applications include furniture. The researchers will present their results today at ACS Fall 2022.
Wind power is becoming popular, but disposing of huge turbine blades is a problem. Today, scientists report a composite resin for making these behemoths that could be recycled into new blades or many other products, including gummy bears. They will present their results at ACS Fall 2022.

Treating allergic mice with a form of butyrate — which is produced by good gut bacteria — protects against peanut allergy, scientists report today. The treatment might also counteract other food allergies and inflammatory diseases. They will present their results at ACS Fall 2022.
Lithium needs to be taken in just the right amount to be effective. Today, scientists report the development of a tiny sensor that detects lithium levels noninvasively from sweat on a fingertip in about 30 seconds. The researchers will present their results at ACS Fall 2022.
Urinary tract infections are common, yet can be tough to treat as the bacteria that cause them become resistant to many antibiotics. In ACS Central Science, researchers report a new molecule that inhibits drug-resistant bacteria in lab experiments, as well as in mice with pneumonia and UTIs.
Drugs called interferon betas are common treatments for multiple sclerosis. Interferon beta, a protein known to contain a zinc-binding pocket, is thought to reduce proinflammatory molecules in MS patients. But researchers now report in ACS Chemical Neuroscience that the molecule reduces the binding of three components — zinc, C-peptide and albumin — to red blood cells.
Journalists who register for the fall meeting of the American Chemical Society will have access to nearly 11,000 presentations on topics including food, energy, pollution mitigation, health and more. ACS Fall 2022 is a hybrid meeting being held virtually and in-person in Chicago on Aug. 21–25.
