Crop improvement often involves the transfer of genetic material from one organism to another to produce a valuable trait. Some major examples of crops with these so-called 'transgenes' include disease-resistant cotton and beta-carotene-enhanced golden rice. However, when foreign DNA is introduced into a host organism, a natural defensive response in plants is to repress or silence the expression...
In a groundbreaking study of people living with HIV, researchers found that elusive white blood cells called neutrophils play a role in impaired T cell functions and counts, as well as the associated chronic inflammation that is common with the virus.
The United States will send a crewed mission to the Moon "no earlier than 2025," NASA chief Bill Nelson told reporters on Tuesday, officially pushing back the launch by at least a year.
A federal agency announced Tuesday that it is taking a step toward designating a new national marine sanctuary off the central California coast that would be named for the region's Indigenous people.
Tiny particles of gold could be the new weapon in the fight against bacterial antibiotic resistance, according to research just published.

Micro-electro-mechanical devices (MEMS) are based on the integration of mechanical and electrical components on a micrometer scale. We all use them continuously in our everyday life: For example, in our mobile phones there are at least a dozen MEMS that regulate different activities ranging from motion, position, and inclination monitoring of the phone; active filters for the different...
The latest national pledges submitted to the UN climate conference in Glasgow to tackle climate change this decade would lead to around 2.4 degrees Celsius of global warming this century, far above safe levels, analysts said on...
The American Dream may have faded, but it is unrealistically—and perhaps detrimentally—alive and well on teenagers' favorite TV programs, according to a report published today by UCLA's Center for Scholars and Storytellers.
Researchers have shown that there is a genetic component underlying the amazing spatial memories of Mountain Chickadees. Although the genetic basis for spatial memory has been shown for humans and other mammals, direct evidence of that connection has never before been identified in birds.
A new database compiling movement of the largest rivers in the world over time could become a crucial tool for urban planners to better understand the deltas that are home to these rivers and a large portion of Earth's population.
Scientists are calling for government transparency around the huge hidden carbon emissions of their armed forces.
A striped design showing the impact of global warming on 170 years of world temperatures at a glance has become a hit at the UN's COP26 climate summit in Glasgow.
Along the banks of the Mystic River in Groton, Zell Steever points to landmarks he doesn't expect to survive climate change.
A felony history carries more than just a social stigma. It can lead to more adults without work—even after paying their debt to society.
A team of physicists and engineers at Lawrence Berkeley National Laboratory (Berkeley Lab) successfully demonstrated the feasibility of low-cost and high-performance radio frequency modules for qubit controls at room temperature. They built a series of compact radio frequency (RF) modules that mix signals to improve the reliability of control systems for superconducting quantum processors. Their...
A remarkably well-preserved fossil elephant cranium from Kenya is helping scientists understand how its species became the dominant elephant in eastern Africa several million years ago, a time when a cooler, drier climate allowed grasslands to spread and when habitually bipedal human ancestors first appeared on the landscape.
For the first time, researchers have shown that there is a genetic component underlying the amazing spatial memories of Mountain Chickadees. These energetic half-ounce birds hide thousands of food items every fall and rely on these hidden stores to get through harsh winters in the mountains of the West. To find these caches, chickadees use highly specialized spatial memory abilities. Although the...
