First Americans arrived in three waves from Siberia

A detailed genetic analysis has settled the question of how and when the first Americans arrived in the continent.

Room temperature quantum bit created

Scientists have taken a big step towards practical quantum computing, with the creation of qubits that can exist in a solid-state system at room temperature.

Future cosmologists doomed by expanding universe

We've arrived late for the cosmic show - too late for the best seat, says Harvard theorist Avi Loeb. He says the ideal time to study the cosmos was more than 13 billion years ago, just half a billion years after the Big Bang.

Red meat consumption linked to early death

Researchers have discovered that eating red meat - any at all - appears to dramatically increase the risk of heart disease and cancer.

Studies wrong to link IQ to specific genes

Most of the genes thought to be linked to human intelligence have nothing to do with it at all, according to Harvard researchers.

'DNA robot' makes cancer self-destruct

Harvard researchers have created a tiny  'DNA robot' that can seek out and destroy specific cells - including cancer cells.

Pop-up origami robots inspired by children's books

Harvard engineers have developed a way to create swarms of 'pop-up' robots to be printed out by the sheet.

Team builds first artificial cell membrane

Chemists have made a big step towards the creation of a completely artificial life form.

La Nina linked to killer flu pandemics

The La Niña weather pattern could be triggering flu pandemics such as 2009's swine flu, scientists suggest.

Insectoid material could replace plastic

Researchers at Harvard University's Wyss Institute for Biologically Inspired Engineering have developed a new super-strong material based on the shells of creatures such as shrimps.

Data mining tool is 'hypothesis generator'

Researchers at Harvard University and MIT's Broad Institute have developed a data mining tool that can detect meaningful patterns in vast data sets.

'3D' transistors promise faster circuits and lighter laptops

A new type of transistor based on a 3D structure could replace silicon chips, say researchers from Purdue and Harvard universities.

Starfish robot shimmies through tight spaces

Harvard University engineers have built a limbo-dancing robot that can squeeze under obstacles in its path for search and rescue missions.

Our galaxy could hold thousands of 'time-bomb' stars

Astrophysicist Rosanne Di Stefano compares it to the Hollywood blockbuster 'Speed' - a newly-described type of star that's destined to explode if it slows down.

Team produces weird optical phenomena - and rewrites the rules of refraction

Researchers at the Harvard School of Engineering and Applied Sciences (SEAS) have induced light rays to behave in a way that defies the laws of reflection and refraction, while producing some weird fun-house images on the way.

Winklevoss twins respond to Harvard pres

After being called "a**holes," the Winklevoss twins have written an amazingly long response to the president of Harvard.

Team develops tools to edit DNA

MIT and Harvard researchers say they can edit the genetic code of a living cell, allowing them to give cells new functions such as building proteins not found in nature, or engineering bacteria that are resistant to any viral infection.

Can people sense Earth's magnetic field?

People may be able to 'see' magnetic fields just as migrating birds do - or, at any rate, have once had the ability to do so in the past.

TV gives you diabetes and heart disease

Stay away from that television - it could kill you. While you might think there's no harm in checking out what the Kardashians are up to,  they could be giving you fatal diseases.

New 'ray gun' can put out fires

A team of chemists has produced a device that they say can put out fires and could be used by firefighters as an alternative to water or foam.
