The design process is being headed by researchers from the Johns Hopkins Applied Physics Laboratory. The goal is to use a refrigerator-sized object to smash into and deflect an asteroid from Earth. Of course, there’s no way such a mission could stop an asteroid that’s poised to smack into the planet in the near future. However, a little nudge early enough might alter an object’s orbit and cause it to miss an impact with Earth.
For the last year, the Curiosity rover has been studying the surface of Mars with more independence than ever before, saving human time and energy. The partly autonomous exploration is also helping people sidestep the constraints of working across vast distances in space. This new capability is powered by software called Autonomous Exploration for Gathering Increased Science, or AEGIS.
A new manufacturing process has been developed that one day may allow us to send life to distant planets, bring living things to earth from extra-terrestrial worlds, change the way we fight viruses, alter our entire approach to biological research, modify our approach to global epidemics, and revolutionize how we manage life on earth.
American scientific teams still publish significantly more biomedical research discoveries than teams from any other country, a new study shows, and the U.S. still leads the world in research and development expenditures. But American dominance is slowly shrinking, the analysis finds, as China's skyrocketing investing on science over the last two decades begins to pay off.
Around the country, science instruction is changing—students are being asked to make models, analyze data, construct arguments, and design solutions in ways that far exceed schools' previous goals. That means science testing, of course, needs to change as well.
A few years back, scientists at the biotechnology company Amgen set out to replicate 53 landmark studies that argued for new approaches to treat cancers using both existing and new molecules. They were able to replicate the findings of the original research only 11 percent of the time. Science has a reproducibility problem. And the ramifications are widespread.
NASA’s Juno spacecraft arrived in orbit of Jupiter last summer, and it began its death-defying dives into Jupiter’s magnetic field earlier this year. It’s on a longer 53-day orbit than originally planned due to engine trouble, but NASA is still gathering lots of information.
The ideal 3D bioprinter, says tissue engineering expert Y. Shrike Zhang, would resemble a breadmaker: “You’d have a few buttons on top, and you’d press a button to choose heart tissue or liver tissue.” Then Zhang would walk away from the machine while it laid down complex layers of cells and other materials. The technology isn’t quite there yet. But the new BioBot 2 printer seems a step in that direction.
In 2011, McKinsey published the report Big data: The next frontier for innovation, competition, and productivity which made significant workforce projections and said that by 2018 “140,000-190,000 more deep analytical talent positions, and 1.5 million more data-savvy managers are needed to take full advantage of big data in the United States”.
Many in the scientific community believe that if the American public were more informed about the science behind climate change and energy issues, people would hold views that aligned more closely with those of scientific experts. But how much people know about science only modestly and inconsistently correlates with their attitudes about climate and energy issues, while partisanship is a stronger factor in people’s beliefs, according to a 2016 Pew Research Center survey.
