Phys.org / Airborne sensors map ammonia plumes in California's Imperial Valley
A recent study led by scientists at NASA's Jet Propulsion Laboratory in Southern California and the nonprofit Aerospace Corporation shows how high-resolution maps of ground-level ammonia plumes can be generated with airborne ...
Medical Xpress / Daily pill helps people lose 10% of weight in 18 months, study finds
A daily pill that is cheaper and easier to take than currently available weight loss drugs helps people lose around a tenth of their body weight over nearly 18 months, a study said Thursday.
Phys.org / Physicists demonstrate the constancy of the speed of light with unprecedented accuracy
In 1887, one of the most important experiments in the history of physics took place. American scientists Michelson and Morley failed to measure the speed of Earth by comparing the speed of light in the direction of Earth's ...
Medical Xpress / Cancer cells have backup metabolic pathway to keep building DNA when blocked, study finds
Northwestern Medicine scientists have uncovered a surprising link between a tiny cellular engine and the way cancer cells build the DNA they need to proliferate, according to a new study published in Molecular Cell.
Phys.org / NASA's Roman could bring new waves of information on galaxy's stars
A team of researchers has confirmed stars ring loud and clear in a "key" that will harmonize well with the science goals and capabilities of NASA's upcoming Nancy Grace Roman Space Telescope.
Phys.org / Smart toilets in Cambodia fall short due to improper use
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was ...
Phys.org / From light to logic: First complete logic gate achieved in soft material using light alone
Researchers from McMaster University and the University of Pittsburgh have created the first functionally complete logic gate—a NAND gate (short for "NOT AND")—in a soft material using only beams of visible light. The ...
Phys.org / Could the solution to the carbon problem be carbon itself?
Can we use carbon to help decarbonize the world and transform the energy and chemical industries? Yes, it seems, but there are some key challenges to overcome first.
Phys.org / Deep imaging suggests isolated galaxy forms stars without signs of past mergers
Using the Two-meter Twin Telescope (TTT3), Spanish astronomers have conducted deep optical imaging of an isolated dwarf galaxy known as NGC 6789. Results of the new observations, presented November 10 on the arXiv preprint ...
Phys.org / Extinct rocket frog species identified from single 62-year-old museum specimen
Anyone walking through the Tarumã neighborhood in Curitiba (the capital of the state of Paraná, Brazil) today may find it difficult to imagine the area as it was in the past. Between the buildings, racetrack, and the city's ...
Phys.org / Light-controlled embryos reveal power of mechanical forces in human development
Only two weeks after fertilization, the first sign of the formation of the three axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, a flat and featureless ...
Phys.org / New fabric reflects 96% of sunlight to keep wearers cooler in extreme heat
As global temperatures rise and heat waves intensify, a new textile innovation co-developed by University of South Australia scientists promises to keep people cooler, drier, and more comfortable in extreme heat.
