I don’t think I ever learned one of those little rhymes – My Very Educated Mother Just Served Us Nine Pizzas – to memorize the order of the planets, but if I had, it would’ve painted for me a minimalist picture of the solar system. (Side question: what is my Very Educated Mother serving now that we only have Dwarf Pizzas?) After all, much of the most exciting work in planetary science today happens not at the planets, but around them.
Ask an astronomer where in the solar system she’d like to visit next and you’re just as likely to hear Europa, Enceladus, Titan, or Triton as you are Venus, Mars, or Neptune. Our solar system hosts eight planets but nearly 200 known moons. And moons, it turns out, are just the start. We’ve detected more than a million asteroids; surely that’s just a fraction of what’s lurking beyond our limits of observation. Let’s not even think about the billions, perhaps even trillions, of Kuiper belt and Oort cloud objects – we could be here all day! So, while the planets may dominate the solar system gravitationally, they are pitiful numerically.(…)
GOLDSTONE, Calif., Jan. 26 (UPI) — NASA has discovered the asteroid 2004 BL86, which just passed Earth, has its own moon.
A team of researchers has demonstrated a new way to change the amount of electrons that reside in a given region within a piece of graphene, they have a proof-of-principle in making the fundamental building blocks of semiconductor devices using the 2-D material.
Successfully treating rabies can be a race against the clock. Those who suffer a bite from a rabid animal have a brief window of time to seek medical help before the virus takes root in the central nervous system, at which point the disease is almost invariably fatal. Now, researchers have successfully tested a treatment on mice that cures the disease even after the virus has spread to the brain.
In the first systematic look at the economic outcomes of hospital-based violence intervention, researchers demonstrate that, in addition to transforming victims’ lives, these programs may indeed save a significant amount of money compared to non-intervention, in various sectors including health care and criminal justice, up to about $4 million to serve 90 clients in a 5-year period.
To survive and fulfill their biological functions, cells need to take in material from their environment. In this process, proteins within the cell pull inward on its membrane, forming a pit that eventually encapsulates the material in a bubble called a vesicle. Researchers have now revealed a relationship that governs this process, known as endocytosis.
A new article outlines many of the potential roles drones can play in university research, and the advantages they can offer in speed, cost and data collection.
Many satellites that monitor the Earth orbit relatively close to the planet, while some satellites that monitor the sun orbit our star. DSCOVR will keep an eye on both, with a focus on the sun. To cover both the Earth and sun, it will have an unusual orbit in a place called L1.
A new breast cancer risk prediction model combining histologic features of biopsied breast tissue from women with benign breast disease and individual patient demographic information more accurately classified breast cancer risk than the current screening standard.
Insomniacs who take longer than 14 minutes to fall asleep face a greater risk of hypertension, according to new research. This study is the first to test whether insomnia with physiological hyperarousal, defined as a longer time to fall asleep, is linked to hypertension.
