Salamanders may not be the cuddliest of animals, but they can regenerate lost limbs and achieve amazing recovery of seriously damaged body parts. Now, a new report identifies a peptide from the skin of salamanders that may be the key to unlocking the secret of this amazing wound healing trick in humans.
A new clinical initiative will determine a breath test’s effectiveness to identify volatile organic compounds in human breath that are biomarkers of chronic obstructive pulmonary disease.
A growing number of consumers are willing to pay a premium for fruits, vegetables and other foods labeled "organic," but whether they're getting what the label claims is another matter. Now, scientists studying conventional and organic tomatoes are devising a new way to make sure farms are labeling their produce appropriately.
A Bronze Age palace excavation has revealed an ancient wine cellar. Wine production, distribution and consumption are thought to have played a role in the lives of those living in the Mediterranean and Near East during the Middle Bronze Age, but little archaeological evidence about Bronze Age wine is available to support art and documentation about the role wine played during this period.
Researchers have developed a method to screen organic materials for organic photovoltaic cells by charge formation efficiency.
A new technique that traps light at the nanoscale to enable real-time monitoring of individual molecules bending and flexing may aid in our understanding of how changes within a cell can lead to diseases such as cancer.
Monoclonal antibodies represent the largest and fastest-growing segment of international biopharma. While these therapeutic agents are a boon for global healthcare, productivity constraints pose a serious challenge. Now, researchers have developed a high-capacity method to purify monoclonal antibodies that uses magnetic nanoparticles and also introduces new operating conditions.
As the FDA mulls over whether to rein in the use of common antibacterial compounds that are causing growing concern among environmental health experts, scientists are reporting that many pregnant women and their fetuses are being exposed to these substances.
Graphene may be tough, but those who handle it had better be tender. The environment surrounding the atom-thick carbon material can influence its electronic performance, according to researchers who have come up with a simple way to spot contaminants.
Countless products are based on ethylene, a simple two-carbon molecule, which requires an energy-intense separation process to pluck the desired chemical away from nearly identical ethane. To eliminate the extreme cooling required in the separation, researchers have designed a material with a porous framework that greatly prefers ethylene.
A team of engineers has created a truly portable device for NMR spectroscopy. They dramatically shrunk the electronic spectrometer components, fitting them on a silicon chip smaller than a sesame seed. Combined with a compact permanent magnet, this minuscule spectrometer represents the smallest device that can presently perform multidimensional NMR spectroscopy.
Coffee drinkers beware: surprise ingredients that are neither sweet nor flavorful may be hiding in your coffee, and growing coffee shortages may increase the chance of having these fillers in your cup of joe in the future. The good news is that a highly accurate test is in the works to quickly find coffee containing unwanted fillers before the beverage reaches stores and restaurants.
Criminals are smuggling an estimated $30 billion in U.S. currency into Mexico each year from the U.S., but help could be on the way for border guards, researchers report. The answer to the problem: a portable device that identifies specific vapors given off by U.S. paper money.
As thousands of vacationers hit the beach this summer, many of them will expose their unprotected bare limbs to direct UV sunlight, potentially putting them at risk of skin cancer later in life. To fight back, scientists turned to light, designing optical devices that may detect cancerous skin lesions early on, leading to better treatment outcomes and ultimately saving lives.
Nanophotonics experts have created a unique sensor that amplifies the optical signature of molecules by about 100 billion times. Newly published tests found the device could accurately identify the composition and structure of individual molecules containing fewer than 20 atoms.
Cocoa farmers will lose an estimated 30 to 40 percent of their crop to pests and disease this year. With chocolate prices having risen globally by roughly two-thirds in the past decade, concern is growing about sustainability in cocoa production. But scientists have found a safe, biodegradable potential alternative to the hazardous antifungal agents currently being used to combat one of the most damaging cacao diseases.
In chambers that mimic Mars' conditions, researchers have shown how small amounts of liquid water could form on the planet despite its below-freezing temperatures. A type of salt present in Martian soil can readily melt ice it touches. But this Martian salt cannot, as some scientists suggested, form liquid water by sucking vapor out of the air through a process called deliquescence.
The warm beauty of amber was captivating and mysterious enough to inspire myths in ancient times, and even today, some of its secrets remain locked inside the fossilized tree resin. But for the first time, scientists have now solved at least one of its puzzles that had perplexed them for decades.
Working with a gene that plays a critical role in HIV infection, researchers have discovered that some human genes have an alternate set of operating instructions written into their protein-making machinery. The alternate instructions can quickly alter the proteins' contents, functions and ability to survive.
Veterinarians are using advanced forensic techniques and the same technology used by crime scene investigators to monitor drug residues in milk and meat. They are working with producers to strengthen food safety and make sure animals are medicated properly.
The humble blowfly could lead to better detection of methamphetamine (MA) in decomposing tissue. Research has explored the effect of MA on the development, growth rates and survival of the blowfly in relation to estimating post-mortem intervals.
