An annual list of groundbreaking scientific achievements, selected by Science, is topped by cancer immunotherapy and includes major breakthroughs in solar cell technologies, genome-editing techniques and vaccine design strategies, to name a few.
Health advocates cheered last month’s U.S. Food and Drug Administration proposal to ban...
All good research breaks new ground, but rarely does the research unearth truths that challenge...
Researchers have successfully tested the conversion of large particles of pinewood char in a gasification process, a step necessary for the mass production of synthetic liquid fuel from recalcitrant biomass.
Plants naturally produce millions of tiny spirals that scientists are turning into nanomotors for use in medicine and other fields.
A new video tracks formation of snowflakes from their origins in bits of dust in clouds that become droplets of water falling to Earth.
Scientists are reporting a new development toward a long-sought insulin pill that could save millions of diabetics the pain of daily shots.
Researchers have created a new type of molecular motor made of DNA and demonstrated its potential by using it to transport a nanoparticle along the length of a carbon nanotube.
A novel method for extracting titanium, often used in wedding bands, could lower its cost and make the strong, lightweight metal more widely accessible.
The lithium-ion batteries that power our laptops, smartphones and electric vehicles could have significantly higher energy density if their graphite anodes were to be replaced by lithium metal anodes.
Chemists have been able to trace narcotics substances and prescription drugs in measurements of wastewater from 33 Swedish sewage treatment plants.
Atoms in a nanocrystal can cooperate with each other to facilitate binding or switching, a phenomenon widely found in biological molecules.
The U.S. government says it has found no evidence that common antibacterial soaps prevent the spread of germs, and regulators want the makers of Dawn, Dial and other household staples to prove that their products do not pose health risks to consumers.
The earliest documentation of fireworks dates back to 7th century China, where they were invented. The art and science of firework making has developed into an independent profession.
A controversial oil and natural gas drilling technique called hydraulic fracturing, or fracking, uses many chemicals that can disrupt the body’s hormones.
A chemical bond discovered by scientists, which is essential for animal life and which hastened the “dawn of the animal kingdom,” could lead to new therapies for cancer and other diseases.
The same tiny cellulose crystals that give trees and plants their high strength, light weight and resilience have now been shown to have the stiffness of steel. The nanocrystals might be used to create a new class of biomaterials with wide-ranging applications, such as strengthening construction materials and automotive components.
Researchers have discovered a tube-shaped structure that forms temporarily in a certain type of virus to deliver its DNA during the infection process and then dissolves after its job is completed.
Easily manufactured, low-cost artificial cells manufactured using microprinting may one day serve as drug and gene delivery devices and in biomaterials, biotechnology and biosensing applications. These artificial cells will also allow researchers to explore actions that take place at the cell membrane.
Teens who were heavy marijuana users- smoking it daily for about three years- had abnormal changes in their brain structures related to working memory, and performed poorly on memory tasks.
Researchers have found a catalyst that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy.
In a case series seemingly tailor-made for cinematic tragedy or farce, emergency physicians report severe botulism poisoning from a batch of potato-based "wine" (also known as pruno) cooked up in a Utah prison.
Sunflower seeds and sunflower oils have been shown to decrease risk of cardiovascular disease as well as have potential beneficial effects on obesity, bone health and blood pressure. Now, a study has shown that the addition of oregano essential oils to sunflower seeds preserved their positive sensory attributes and freshness.
Bioengineers have developed a hydrogel scaffold for craniofacial bone tissue regeneration that starts as a liquid, solidifies into a gel in the body and liquefies again for removal. The gel conforms to irregular 3D spaces and provides a platform for functional and aesthetic tissue regeneration.
Researchers have discovered that some banana varieties accumulate specific plant toxins in the immediate vicinity of root tissue that has been attacked by parasites. This local accumulation is crucial for the plant’s resistance to the pest.
Understanding the science behind pain, from a simple “ouch” to the chronic and excruciating, has been an elusive goal for centuries. But now, scientists describe the development of a new technique, which they tested in rats, that could result in better ways to relieve pain and monitor healing.
Through lotions, shampoos and other personal care products (PCPs), infants and toddlers are likely becoming exposed to potentially harmful substances, called parabens, at an even higher level than adult women in the U.S.
Scientists are developing classifications in order to better differentiate readily biodegradable from long-lasting pesticides.
