Science-fiction writers have long envisioned human–machine hybrids that wield extraordinary powers. However, “super plants” with integrated nanomaterials may be much closer to reality than cyborgs.
Attend press conferences live – online at http://bit.ly/ACSLive_Orlando2019 or in person -- at the Spring 2019 National Meeting & Exposition of the American Chemical Society (ACS). Press conferences will be held Monday, April 1, through Wednesday, April 3, 2019. Below is the schedule, which will be updated as needed.
Wood may seem more at home in log cabins than modern architecture, but a specially treated type of timber could be tomorrow’s trendy building material. Today, scientists report a new kind of transparent wood that not only transmits light, but also absorbs and releases heat, potentially saving on energy costs.
Hundreds of everyday items contain organophosphate ester (OPE) flame retardants and plasticizers. Some of these compounds make their way into the air, onto surfaces and even inside our bodies, with uncertain health effects.
Just as controlled-release medications slowly dole out their cargo after they experience a pH change in the body, implanted “artificial muscles” could someday flex and relax in response to light illuminating the skin. In pilot studies, scientists have developed a new material that expands and contracts.
When an act of terrorism or a vehicle or industrial accident ignites fuel, the resulting fire or explosion can be devastating. Today, scientists will describe how lengthy but microscopic chains of polymers could be added to fuel to significantly reduce the damage from these terrifying incidents without impacting performance.
Traditional surgery to reshape a nose or ear entails cutting, sometimes followed by long recovery times and scars. Now, researchers have developed a “molecular surgery” process using tiny needles, electric current and 3D molds to reshape living tissue with no incisions, scarring or recovery time.
From computer hard discs and smart phones to earbuds and electric motors, magnets are at the forefront of today’s technology. Magnets containing rare-earth elements are among the most powerful available, allowing many everyday objects to be ever smaller.
Nature has evolved protein-based substances with mechanical properties that rival even the best synthetic materials. Pound for pound, spider silk is stronger and tougher than steel. But unlike steel, the natural fiber cannot be mass-produced.
Prehistoric rock paintings are a source of fascination. Aside from their beauty, there’s deep meaning in these strokes, which depict ancient rituals and important symbols. Scientists now describe use of “X-ray vision” to gain brand-new insights about the layers of paint in rock art without needless damage.
There’s nothing like a glass of orange juice, but prices have soared as the Florida citrus industry fights a citrus greening disease epidemic that's been drying out oranges and reducing crop yield. There’s no cure, but researchers report they have identified a fungal compound that may inhibit the bacteria.
If you’ve ever dreamed about getting a good night’s sleep, your answer may someday lie in data generated by your sleepwear. Researchers have developed pajamas embedded with self-powered sensors that provide unobtrusive and continuous monitoring of heartbeat, breathing and sleep posture.
Major depression, obesity and chronic pain are all linked to the effects of one protein, called FKBP51. Researchers have now developed a highly selective compound that can effectively block FKBP51 in mice, relieving chronic pain and having positive effects on diet-induced obesity and mood.
Drawing inspiration from nature, researchers are making polymers with ever-more precise compositions on demand. Using multistep synthesis tools pulled from biology, a group is reporting that it is developing ultra-high precision synthetic polymers with precisely controlled chain lengths.
Fentanyl’s powerful effects are long-lasting, and even tiny amounts of the drug can lead to an overdose. Antidotes, do not last long enough in the body to fully counter the drug, requiring repeated injections. Now, scientists report that they are developing single-dose, longer-lasting opioid antidotes.
As current antibiotics dwindle in effectiveness against multidrug-resistant pathogens, researchers are seeking potential replacements in some unlikely places. Now a team has identified bacteria with promising antibiotic activity against known pathogens.
Freshly distilled, un-aged whiskey is filtered over charcoal made from the sugar maple tree in a mysterious, but necessary step known as the Lincoln County Process. By law, a product cannot be called Tennessee whiskey without it. Researchers have clues as to what the process imparts to the final product.
Aiming a laser beam at an aircraft isn’t a harmless prank: The sudden flash of bright light can incapacitate the pilot, risking the lives of passengers and crew. Today, researchers report liquid crystals that could someday be incorporated into aircraft windshields to diffuse any wavelength of laser light.
According to the Centers for Disease Control and Prevention, Down syndrome is the most common birth defect, occurring once in every 700 births. However, traditional non-invasive prenatal tests for the condition are unreliable or carry risks for the mother and fetus. Now, researchers have developed a sensitive new biosensor that could someday be used to detect fetal Down syndrome DNA in pregnant women’s blood. They report their results in the ACS journal Nano Letters.
Vaccines have saved millions of lives, but nobody likes getting a shot. That’s why scientists are trying to develop oral vaccines for infectious diseases. But to be effective, the vaccine must survive digestion and reach immune cells within the intestinal wall. Now, researchers reporting in the ACS journal Nano Letters have developed oral vaccines powered by micromotors that target the mucus layer of the intestine.
