Ion engines could take us to the solar gravitational lens in less than 13 years, suggests paper
Sending an object to another star is still the stuff of science fiction. But some concrete missions could get us at least part way there. These "interstellar precursor missions" include a trip to the solar gravitational lens point at 550 AU from the.....»»
Optical technique that uses orbital angular momentum could transform medical diagnostics
An Aston University researcher has developed a new technique using light that could revolutionize non-invasive medical diagnostics and optical communication. The research showcases how a type of light called the orbital angular momentum (OAM) can be.....»»
Did some of Earth"s water come from the solar wind?
The source of Earth's water is an enduring mystery that extends to exoplanets and the notion of habitability. In broad terms, Earth's water was either part of the planet from the beginning of its formation in the solar nebula or delivered later, mayb.....»»
Scientists make Wile E. Coyote observation, confirming theory of how solar flares are created
An international collaboration that includes an Oregon State University astrophysicist has identified a phenomenon, likened to the quick-footed movements of an iconic cartoon predator, that proves a 19-year-old theory regarding how solar flares are c.....»»
Blasts from the past: New insights from old space storms
On 4 August 1972, a burst of solar plasma rocked Earth's magnetic field after hurtling through space for about 14.6 hours—the fastest sun-to-Earth plasma journey ever recorded. The resulting space storm, one of several that occurred from 2 to 11 Au.....»»
Students at Historically Black Colleges and Universities face barriers to medical school admission, study finds
There are 45.3 million African Americans living in the United States and they represent 13.6% of the U.S. population, according to the U.S. Census Bureau. But only 5.7% of physicians in the United States self-identify as Black, despite multiple effor.....»»
NASA begins new deployable solar array tech demo on Pathfinder spacecraft
NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft's systems including its on-board electronics as well as the payload's support systems such as the.....»»
Crucial role of peer support for African American doctoral students at predominantly white institutions
A new study conducted by researchers at George Washington University sheds light on the critical role that same-race peer groups play in the success of African American doctoral students at predominantly white institutions (PWIs). The research unders.....»»
How bioacoustics and AI can help study animal populations in the forest and beneath the waves
Animal sounds combined with artificial intelligence (AI) can revolutionize biodiversity monitoring both on land and in aquatic settings according to researchers from the University of Copenhagen. By analyzing wildlife sounds, AI can now identify spec.....»»
High-resolution, nanoscale imaging method could accelerate the discovery of more durable materials
Take a photo with your phone and you might see wonderful details—leaves on a tree, strands of hair blowing in the wind. The width of that strand of hair is 100,000 nanometers wide. The best traditional laboratory microscope that uses light may capt.....»»
