Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting the drugs directly to the tumors. Now, chemists have devised a new way to build nanoparticles that can carry and deliver three or more different drugs.
In a new video, researchers look at the science behind the world's most popular drug, caffeine, including why it keeps you awake and how much is too much.
French investigators have begun taking DNA samples from 527 male students and staff at a high school— including boys as young as 14— as they search for the assailant who raped a teenage girl on the closed campus.
Pork products cost about 10 percent more than they did last year, and economists expect the prices to continue rising because of diarrhea viruses currently devastating the pork industry. That's why researchers have developed new tests they hope will mitigate the spread of these viruses.
The problem with solar power is that sometimes the sun doesn’t shine. Now, scientists have come up with an ingenious workaround— a material that can absorb the sun’s heat and store that energy in chemical form, ready to be released again on demand.
New research shows that fruit flies are secretly harboring the biochemistry needed to glow in the dark— otherwise known as bioluminescence.
Research may turn an enzyme that acts as a specialized “wrench” in antibiotic assembly into a set of wrenches that will allow for greater customization. By modifying this enzyme, scientists hope to be able to design and synthesize stronger, more adaptable antibiotics from less expensive, natural compounds.
Cell phone scrap can contain precious metals, such as gold and copper. Now, researchers have developed a biological filter, made of mushroom mycelium mats, enabling recovery of as much as 80 percent of the gold in electronic scrap.
Porous silicon, manufactured in a bottom up procedure using solar energy, can be used to generate hydrogen from water, according to mechanical engineers, who also see applications for batteries, biosensors and optical electronics as outlets for this new material.
The Food and Drug Administration is taking steps to ensure that shoppers who buy honey are getting the real deal. New guidance issued this week would prevent food companies from adding sugar or other sweeteners to pure honey and still calling it "honey."
A pH-sensitive microchip, invented by chemists, could improve postoperative care for patients with knee replacements and other surgical implants.
Researchers have developed a simple approach to applying a coating of thin, flat nanoplatelets— using a common spray gun— that spontaneously self-assemble into “nanowalls.” The nanowalls act as rigid barriers that prevent oxygen gas from reaching the surface of objects prone to corrosion.
Experiments have explained the behavior of electrons at tiny step edges on titanium oxide surfaces. This is important for solar cell technology and novel, more effective catalysts.
One theory about the origin of life is that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research has found that it may not have been as easy as previously assumed. Instead, the finds could provide a focus for the search for life on other planets.
Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer.
According to EU guidelines, the new compound R1234yf should, in the future, be used as the refrigerant in air-conditioning systems for automobiles. But the compound is inflammable, and chemists have shown that combustion of the cooling agent leads to the formation of the highly toxic carbonyl fluoride.
A fast diagnosis and treatment can mean the difference between life and death for stroke victims. So scientists are working on a new blood test that one day could rapidly confirm whether someone is having a stroke and what kind.
Scientists have created a copper-based catalyst that produces large quantities of ethanol from carbon monoxide gas at room temperature.
In the fight against “superbugs,” scientists have discovered a class of agents that can make some of the most notorious strains vulnerable to the same antibiotics that they once handily shrugged off.
On the less glamorous side of space exploration, there’s the more practical problem of waste— in particular, what to do with astronaut urine. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and much-needed drinking water.
Synthetic genetic circuitry is helping researchers see, for the first time, how to regulate cell mechanisms that degrade the misfolded proteins implicated in Parkinson’s, Huntington’s and other diseases.
A bioengineer won a contest to develop a 21st century chemistry set. His version, based on a toy music box, is small, robust, programmable and costs five dollars.
Energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This find may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
Chemists have set nanotubes into graphene in a way that not only mimics how steel rebar is used in concrete but also preserves and even improves the electrical and mechanical qualities of both.
Chemists have found that cellulose– the most abundant organic polymer on Earth and a key component of trees– can be heated in a furnace in the presence of ammonia, and turned into the building blocks for supercapacitors.
