Ant farmers boost plant nutrition‎

Humans began cultivating crops about 12,000 years ago. Ants have been at it rather longer. Leafcutter ants, the best-known insect farmers, belong to a lineage of insects that have been running fungus farms based on chopped-up vegetable matter for over 50 million years. The ant farming of flowering plants, however, started more recently, about 3 million years ago in the Fiji Islands.

Why money cannot 'buy' housework‎

If a man is handy with the vacuum cleaner, isn't averse to rustling up a lush family meal most nights after he's put on the washing machine having popped into the supermarket on his way home then it's more than likely his partner will have her own bank account.

Check your settings if you don't want Google tracking every move‎

I stepped out of the car and took a visit to a local hotel here right off the main road. It was so easy to find, I didn't have to use Google Maps to get there.

Study finds people prefer to donate time—even when charities lose out‎

Each year during the holiday season, soup kitchens and charities alike are flooded with offers to volunteer. But is a donation of your time most beneficial to the charity, or would a financial contribution provide more value?

Researchers explain visible light from 2-D lead halide perovskites‎

Researchers drew attention three years ago when they reported that a two-dimensional perovskite—a material with a specific crystal structure—composed of cesium, lead and bromine emitted a strong green light. Crystals that produce light on the green spectrum are desirable because green light, while valuable in itself, can also be relatively easily converted to other forms that emit blue or red light, making it especially important for optical applications ranging from light-emitting devices to sensitive diagnostic tools.

New theory for trapping light particles aims to advance development of quantum computers‎

Quantum computers, which use light particles (photons) instead of electrons to transmit and process data, hold the promise of a new era of research in which the time needed to realize lifesaving drugs and new technologies will be significantly shortened. Photons are promising candidates for quantum computation because they can propagate across long distances without losing information, but when they are stored in matter they become fragile and susceptible to decoherence. Now researchers with the Photonics Initiative at the Advanced Science Research Center (ASRC) at The Graduate Center, CUNY have developed a new protocol for storing and releasing a single photon in an embedded eigenstate—a quantum state that is virtually unaffected by loss and decoherence. The novel protocol, detailed in the current issue of Optica, aims to advance the development of quantum computers.
