How birds learn

Children are constantly learning new things, but whether they find it easy or hard to generalise what they have learned and apply it to new situations can depend on how they learned it. It is much the same for songbirds. In their first few months of life, they too must ... Read More »

Easter Island’s society might not have collapsed

You probably know Easter Island as “the place with the giant stone heads.” This remote island 2,300 miles off the coast of Chile has long been seen as mysterious — a place where Polynesian seafarers set up camp, built giant statues, and then destroyed their own society through in-fighting and ...

Parker Solar Probe launches on historic journey to touch the sun

Hours before the rise of the very star it will study, NASA’s Parker Solar Probe launched from Florida Sunday to begin its journey to the Sun, where it will undertake a landmark mission. The spacecraft will transmit its first science observations in December, beginning a revolution in our understanding of ... Read More »

First particle accelerator beam measurement in six dimensions

The first full characterization measurement of an accelerator beam in six dimensions will advance the understanding and performance of current and planned accelerators around the world. A team of researchers led by the University of Tennessee, Knoxville conducted the measurement in a beam test facility at the Department of Energy’s ... Read More »

Laziness helped lead to extinction of Homo erectus

New archaeological research from The Australian National University (ANU) has found that Homo erectus, an extinct species of primitive humans, went extinct in part because they were ‘lazy’. An archaeological excavation of ancient human populations in the Arabian Peninsula during the Early Stone Age, found that Homo erectus used ‘least-effort ... Read More »

Glaucoma may be an autoimmune disease

Glaucoma, a disease that afflicts nearly 70 million people worldwide, is something of a mystery despite its prevalence. Little is known about the origins of the disease, which damages the retina and optic nerve and can lead to blindness. A new study from MIT and Massachusetts Eye and Ear has ... Read More »

Pairs of small colliding galaxies may seed future stars

A pair of dwarf galaxies closely circling the Milky Way, the Large and Small Magellanic Clouds, were in the throes of merging into one when they fell into our galaxy. The duo is thought to hold enough gas to replenish half of the Milky Way’s supply of star-making fuel, and ... Read More »

Ultrahot planets have starlike atmospheres

Recent observations by NASA’s Hubble and Spitzer space telescopes of ultrahot Jupiter-like planets have perplexed theorists. The spectra of these planets have suggested they have exotic — and improbable — compositions. However, a new study just published by a research team that includes Arizona State University astrophysicist Michael Line, an ... Read More »

Neuroscientists get at the roots of pessimism

Many patients with neuropsychiatric disorders such as anxiety or depression experience negative moods that lead them to focus on the possible downside of a given situation more than the potential benefit. MIT neuroscientists have now pinpointed a brain region that can generate this type of pessimistic mood. In tests in ... Read More »

Introducing the latest in textiles: Soft hardware

The latest development in textiles and fibers is a kind of soft hardware that you can wear: cloth that has electronic devices built right into it. Researchers at MIT have now embedded high speed optoelectronic semiconductor devices, including light-emitting diodes (LEDs) and diode photodetectors, within fibers that were then woven ...

There and back again: Mantle xenon has a story to tell

The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to start incorporating and retaining volatile compounds from the atmosphere in the mantle before spewing them out again through volcanic eruptions. This transport could not have begun much before 2.5 billion years ... Read More »

Novel approach to coherent control of a three-level quantum system

For the first time, researchers were able to study quantum interference in a three-level quantum system and thereby control the behavior of individual electron spins. To this end, they used a novel nanostructure, in which a quantum system is integrated into a nanoscale mechanical oscillator in form of a diamond ... Read More »
