Imagine being able to shape a pulse of light in any conceivable manner--compressing it, stretching it, splitting it in two, changing its intensity or altering the direction of its electric field.

AMES, Iowa - Search and rescue crews are already using drones to locate missing hikers. Farmers are flying them over fields to survey crops. And delivery companies will soon use drones to drop packages at your doorstep.

A new study shows that vaccination may reduce the impact of white-nose syndrome in bats, marking a milestone in the international fight against one of the most destructive wildlife diseases in modern times.

WEST LAFAYETTE, Ind. - Precise measurements are critical to the discovery, development and usage of medications. Major financial and scientific decisions within pharmaceutical companies are informed by the outcomes of chemical and biological analyses. Even slight measurement variations can add risk and uncertainty in these high-stakes decisions.

Scientists have discovered a new method for quickly and efficiently mapping the vast network of connections among neurons in the brain.

Researchers combined infrared laser stimulation techniques with functional magnetic resonance imaging in animals to generate mapping of connections throughout the brain. The technique was described in a study published in the journal Science Advances.

(Gothenburg, Sweden): Industry fire-safety experts from the oil and gas and aviation sectors are joining with firefighter trade unions to urge governments to protect human health and the environment with a global ban on the toxic chemical, PFOA, and to reject loopholes for its use in firefighting foams. The use of PFOA and other fluorinated organic compounds (PFAS) is widespread across many industrial and domestic applications including textiles, food packaging, stain and oil resistant treatments, and industrial processes.

Hydrogen is a critical component in the manufacture of thousands of common products from plastic to fertilizers, but producing pure hydrogen is expensive and energy intensive. Now, a research team at Princeton University has harnessed sunlight to isolate hydrogen from industrial wastewater.

In a paper published Feb. 19 in the journal Energy & Environmental Science, the researchers reported that their process doubled the currently accepted rate for scalable technologies that produce hydrogen by splitting water.

ITHACA, N.Y. - Cornell University-led research reports that two local fungal pathogens could potentially curb an invasive insect that has New York vineyard owners on edge.

The spotted lanternfly feeds on more than 70 plant species, including grape vines and apple trees.

In recent years, the market for direct-to-consumer genetic testing has exploded. The number of people who used at-home DNA tests more than doubled in 2017, most of them in the U.S. About 1 in 25 American adults now know where their ancestors came from, thanks to companies like AncestryDNA and 23andMe.

When spies meet, they use secret handshakes to confirm their identities, ensuring they are who they say they are. Now, researchers at Stevens Institute of Technology, and colleagues, have solved a 15-year-old problem that allows handshake-style encryption to be used for time-delayed digital communications such as email - a challenge once thought to be impossible.

ISTANBUL, TURKEY - In a paper published in the Journal of Biological Chemistry, Dr. Özdemir has studied two protein families named Rho GTPases and IQGAPs, which are known to play an important role in cancer metastasis. These two "suspicious" protein families have been studied by many researchers over the years, but the interaction between them had not previously been fully understood.

ARLINGTON HEIGHTS, IL - (APRIL 30, 2019) - Many children with asthma think they are using their asthma inhaler medications correctly when they are not. This makes it very difficult to keep their asthma under control. A new study in Annals of Allergy, Asthma and Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI) finds African American school children, along with their parents, had misplaced confidence in their asthma inhaler technique.

New study of University of Jyvaskyla and Aalto University shows that nanostructures constructed of DNA molecules can be programmed to function as pH-responsive cargo carriers, paving the way towards functional drug-delivery vehicles.

Biodegradable plastic bags are still capable of carrying full loads of shopping after being exposed in the natural environment for three years, a new study shows.

Researchers from the University of Plymouth examined the degradation of five plastic bag materials widely available from high street retailers in the UK.

They were then left exposed to air, soil and sea, environments which they could potentially encounter if discarded as litter.

Like memories in computers, quantum memories are essential components for quantum computers - a new generation of data processors that obey quantum mechanics laws and can overcome the limitations of classical computers. They may push boundaries of fundamental science and help create new drugs, explain cosmological mysteries, or enhance accuracy of forecasts and optimization plans with their potent computational power.
