When it comes to selecting between the best science toys brands, things can be confusing. The top brands and its reputation does make an impact on the choices you have on offer. Cheaply-priced faucets are just that – cheap. science toys and fittings are more like investments, and you wouldn’t want to spend huge in repairs and replacement, which is why selecting a known and reliable brand is important.

Astronomers have been pondering the nature of our first interstellar visitor ever since its discovery. ‘Oumuamua is bizarre -- not only is it from beyond the stars, but it’s also long and cigar-shaped. That led some to wonder if it wasn’t really an alien spacecraft, but past studies of ‘Oumuamua have suggested that it’s just a space rock.

The mirror world, assuming it exists, would have its own laws of mirror-physics and its own mirror-history. You wouldn’t find a mirror version of yourself there (and no evil Spock with a goatee -- sorry "Star Trek" fans). But current theory allows that you might find mirror atoms and mirror rocks, maybe even mirror planets and stars. Collectively, they could form an entire shadow world, just as real as our own but almost completely cut off from us.

Tom Kalil served in the White Houses for two presidents (Obama and Clinton), helping to design and launch national science and technology initiatives in areas such as nanotechnology, the BRAIN initiative, data science, STEM education, and the federal use of incentive prizes. He spoke with Spotlight about the role of science and technology in addressing societal challenges such as promoting opportunity and diminishing income inequality.

Most of what we know about Saturn’s moon Titan comes from the Cassini probe, which studied it repeatedly during its 13-year mission orbiting Saturn. Cassini is gone, but Titan is going to get another robotic visitor in the coming years. NASA has given the green light to the Dragonfly mission, a project to send a multi-rotor flying vehicle to the surface of Titan. This mission is on track to make history in more ways than one.

The poll by The Associated Press and the NORC Center for Public Affairs Research, released Thursday, one month before the 50th anniversary of the Apollo 11 moon landing, lists asteroid and comet monitoring as the No. 1 desired objective for the U.S. space program. About two-thirds of Americans call that very or extremely important, and about a combined 9 in 10 say it's at least moderately important.

Mars is home to dust storms, several robots, and as of today, a new crater. Images from the Mars Reconnaissance Orbiter (MRO) show a fresh impact crater on the surface. Conditions on Mars may eventually sweep the details away, but the reliable probe has spotted the crater while it’s still sharp.

NASA's Curiosity Rover has detected the highest ever levels of methane in the course of its mission on Mars, an exciting discovery because the gas could point to the existence of microbial life. But the methane could also be produced as a result of interactions between rocks and water.

American businesses will help NASA land astronauts on the Moon in five years and establish a sustainable presence there, as part of the agency's larger Moon to Mars exploration approach. NASA has selected 363 proposals from small businesses and research institutions across 41 states to help advance the types of capabilities needed for those future missions, as well as to support the agency in other areas.

A rise in US visa denials for Chinese academics and intensified scrutiny of alleged links to Beijing over fears of potential espionage are having a chilling effect on long-standing research collaboration, researchers say. American and Chinese scientists have co-authored thousands of papers each year, far outpacing the output from scientific collaborations between any other two nations, according to a 2018 survey by academic database Nature Index.
