Are we there...
Today (Dec. 30), a team of researchers from the University of California, San Francisco and the Children’s National Hospital in Washington, D.C., published the results of an investigation into whether or not pharmacy workers could provide accurate information on the disposal of two classes of drugs: opioids and antibiotics. The results are frightening: The researchers enlisted volunteers...

The simultaneous use of antibodies based on two differing mechanisms of action leads to a more effective destruction of tumors. This has been demonstrated by a study in animal models by medical oncologists and scientists. Patients who do not respond to current immunotherapy options could benefit most from this new treatment.
Life as we know it requires phosphorus, and lots of it. But phosphorus is scarce. A new study reports that certain types of carbonate-rich lakes, which could have formed on early Earth, have the right chemistry to keep phosphorous levels high and available to organisms.
The theoretical notion of a 'quantum heat engine' has been around for several decades. It was first introduced around sixty years ago by Scovil and Schulz-DuBois, two physicists at Bell Labs who drew an analogy between three-level masers and thermal machines.
The American coot is a somewhat drab water bird with gray and black feathers and a white beak, common in wetlands throughout North America. Coot chicks, however, sport outrageously bright orange and red feathers, skin, and beaks. A new study explains how the bright coloring of coot chicks fits in with the reproductive strategy of their less colorful parents.
Life as we know it requires phosphorus. It's one of the six main chemical elements of life, it forms the backbone of DNA and RNA molecules, acts as the main currency for energy in all cells and anchors the lipids that separate cells from their surrounding environment.
Research on fossilized fish from the late Devonian period, roughly 375 million years ago, details the evolution of fins as they began to transition into limbs fit for walking on land.
When Nalini Nadkarni was a kid, she'd run home from school, climb into one of the eight maple trees in her parents' backyard and spend an afternoon there with an apple and a book.
A growing number of Chinese scientists working in the United States and other parts of the world are returning to their homeland, enhancing China's research productivity.
For the past few months Hasan Zaidi's phone has been ringing nonstop with calls from desperate residents in Pakistan hoping to get their hands on his newly invented air purifier as smog blankets the country.
Dense fog and hazardous air pollution blanketed northern India and disrupted hundreds of flights on Monday, as harsh winter weather sent temperatures plunging to near-record lows.
What will people remember about the year 2019 in the year 3019? Just as they're likely to recall 1969 as the year humans first walked on the moon, they might well hold up the first portrait of a black hole as this year's most memorable achievement. By that measure, there's little question that the Event Horizon Telescope's radio view of M87's supermassive black hole, 55 million...
Not too long ago Coral Ben-Aharon, a 15-year-old sophomore at Granada Hills Charter High School, didn't bother to use her school's recycling bins—and didn't know how plastic waste contributes to greenhouse gas emissions.
