Researchers have developed the first ever, evidence-based model that can predict with up to 90 percent accuracy the amount of nicotine emitted by an electronic cigarettes.
How online shoppers respond when faced with wide variations in online reviews can give retailers insights into how to display the reviews and what to expect.
Do you ever notice how stress and mental frustration can affect your physical abilities? When you are worried about something at work, do you find yourself more exhausted at the end of the day? This phenomenon is a result of the activation of a specific area of the brain when we attempt to participate in both physical and mental tasks simultaneously.
The number one cause of malnutrition in American pets is obesity. Research experts share causes, implications and potential solutions to this epidemic.
A new study helps explain why the candidate vaccine used in the HVTN 505 clinical trial was not protective against HIV infection despite robustly inducing anti-HIV antibodies: the vaccine stimulated antibodies that recognized HIV as well as microbes commonly found in the intestinal tract, part of the body's microbiome.
By analyzing the natural mechanics of the water strider that enable it to launch off water's surface scientists have emulated this extreme form of locomotion in novel robotic insects.
Two key physical phenomena take place at the surfaces of materials: catalysis and wetting. A catalyst enhances the rate of chemical reactions; wetting refers to how liquids spread across a surface. Non-wetting surfaces promote chemical reaction rates, new research confirms.
North of the Aleutian Islands, submarine canyons in the cold waters of the eastern Bering Sea contain a highly productive 'green belt' that is home to deep-water corals as well as a plethora of fish and marine mammals.
Five men with complete motor paralysis were able to voluntarily generate step-like movements thanks to a new strategy that non-invasively delivers electrical stimulation to their spinal cords. The strategy, called transcutaneous stimulation, delivers electrical current to the spinal cord by way of electrodes strategically placed on the skin of the lower back. This expands to nine the number of completely paralyzed individuals who have achieved voluntary movement while receiving spinal stimulation.
Highly active anti-retroviral therapy has helped millions survive the human immunodeficiency virus. Unfortunately, HIV has a built-in survival mechanism, creating reservoirs of latent, inactive virus that are invisible to both HAART and the immune system. But now, researchers have identified a compound that activates latent HIV, offering the tantalizing possibility that the virus can be flushed out of the silent reservoirs and fully cured.
New findings have implications for questions regarding how animals and plants grow minerals into shapes that have no relation to their original crystal symmetry, and why some contaminants are difficult to remove from stream sediments.
It is possible to predict the timing and intensity of influenza outbreaks in subtropical climates like Hong Kong where flu seasons can occur at different times and more than once during a year, scientists have shown for the first time.
Since 2010, the best estimate of the age of Earth's magnetic field has been 3.45 billion years. But now a researcher responsible for that finding has new data showing the magnetic field is far older.
In a global study of drought impacts, forest trees took an average of two to four years to resume normal growth rates, a revelation indicating that Earth's forests are capable of storing less carbon than climate models have assumed.
A little recognition for a job well done means a lot to children with Attention Deficit/Hyperactivity Disorder -- more so than it would for typically developing kids.
A set of recommendations has been released by experts for how states across the US can improve HIV prevention and care outcomes in an effort to achieve the goals identified within the National HIV/AIDS Strategy.
Researchers report that they have designed a cheap prosthetic knee that mimics normal walking motion. The team reports that it has calculated the ideal torque that a prosthetic knee should produce, given the mass of the leg segments, in order to induce able-bodied kinematics, or normal walking.
Researchers are part of a team of scientists with the Sloan Digital Sky Survey (SDSS) that created a new map of the Milky Way that shows nearly a third of the stars have dramatically changed their obits.
Astronomers have confirmed the existence of a Uranus-sized exoplanet orbiting far from its central star, discovered through a technique called gravitational microlensing.
Researchers have reconstructed an ancient virus that is highly effective at delivering gene therapies to the liver, muscle, and retina. This discovery could potentially be used to design gene therapies that are not only safer and more potent than therapies currently available, but may also help a greater number of patients.
