Fighting superbugs with nanotechnology and light

Quantum dots - minuscule semiconductor particles with specific light-absorption properties - can kill drug-resistant superbugs without harming the surrounding healthy tissue.

Picture of Pluto further refined by months of New Horizons data

After last summer’s Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here’s some of what scientists have learned so far from that rich, slow cache.

Beyond today’s crowdsourced science to tomorrow’s citizen science cyborgs

Computers are getting better and better at the jobs that previously made sense for researchers to outsource to citizen scientists. But don’t worry: there’s still a role for people in these projects.

How much math do you need to win your March Madness pool?

You want to pick the ‘favorites,’ to get accuracy points. But you also want to pick some ‘underdogs,’ to set yourself apart from the pack. Somewhere in the middle is an optimal solution.
Drivers make some suboptimal routing decisions when they’re traveling around town. A. Lima et al. J. R. Soc. Int. DOI: 10.1098/rsif.2016.0021

Recalculating! By not driving the optimal route, you’re causing traffic jams

No wonder you’re always late. Drivers use a route that minimizes travel time on only a third of their trips. Here’s how real-world data can help planners fight traffic congestion.

A new way to detect tsunamis: cargo ships

Reliably predicting whether a tsunami is large enough to require evacuations requires many more observations from the deep ocean than we now have.

Is your March Madness bracket really better than mine?

Simply filling out a bracket – even with random or uninformed choices – is enough to boost your confidence in success, and to get you to put more money on the line.
This “pi plate” shows some of the progress toward finding all the digits of pi. Piledhigheranddeeper

The search for the value of pi

On the occasion of Pi Day, a look at the history of calculating the actual, and increasingly exact, value of pi (π).

Can we ‘vaccinate’ plants to boost their immunity?

Modern agriculture is synonymous with monoculture. That lack of diversity is bad news for plants’ natural immune defenses. Researchers are figuring out how to help plants fend off microbes – without pesticides.

Beyond silicon: the search for new semiconductors

As we reach the limits of what can be done with silicon, the search for new and improved superconductors is on.

Voters who oppose politicians are the most active

Opposition inspires more confidence in one’s position than support and also helps to turn judgments into actions. This helps explain why attack ads are a crucial tool in politicians’ arsenals.

Beyond invisibility: engineering light with metamaterials

We are beginning to be able to control very precisely how light interacts with matter, creating opportunities for invisibility, soundproofing and even earthquake damage prevention.
