‘Seeing’ the other side of our galaxy

Astronomers have successfully traced a spiral arm on the far side of our Galaxy, an accomplishment that provides new insights into the structure of the Milky Way. Efforts to observe the far side of our Galaxy have been hampered by the vast distance and interstellar dust that blocks optical light from those regions. Here, Alberto Sanna and colleagues used radio ...

Reducing racial bias in children

We tend to see people we’re biased against as all the same. They are “those people.” Instead of thinking of them as specific individuals, we lump them into a group. Now an international team of researchers suggests that one way to reduce racial bias in young children is by teaching them to distinguish among faces of a different race. The ...

Goodbye, login. Hello, heart scan

Forget fingerprint computer identification or retinal scanning. A University at Buffalo-led team has developed a computer security system using the dimensions of your heart as your identifier. The system uses low-level Doppler radar to measure your heart, and then continually monitors your heart to make sure no one else has stepped in to run your computer. The technology is described ...

Dino-killing asteroid’s impact on bird evolution

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That’s one conclusion drawn by the authors of a new study published in Systematic Biology. Cornell University Ph.D. candidate Jacob Berv and University of Bath Prize Fellow Daniel Field ...

A more complete picture of the nano world

They may be tiny and invisible, says Xiaoji Xu, but the aerosol particles suspended in gases play a role in cloud formation and environmental pollution and can be detrimental to human health. Aerosol particles, which are found in haze, dust and vehicle exhaust, measure in the microns. One micron is one-millionth of a meter; a thin human hair is about ...

Noninvasive eye scan could detect key signs of Alzheimer’s years before patients show symptoms

Cedars-Sinai neuroscience investigators have found that Alzheimer’s disease affects the retina — the back of the eye — similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer’s disease years before patients experience symptoms. Using a high-definition eye scan developed especially for the study, researchers ...

Oldest 8500-year-old Copper Smelting Unit Unearthed in Turkey

A team of archaeological scientists have found the earliest copper smelting event at the Late Neolithic site of Çatalhöyük in central Turkey, confirming the claim of the site’s archaeological importance. Whether metallurgy was such an exceptional skill to have only been invented once or repeatedly at different locations is therefore still contentious. The proponents of the latter have just provided ...

Sleep or sex? How the fruit fly decides

Choosing between sex or sleep presents a behavioral quandary for many species, including the fruit fly. A multi-institution team has found that, in Drosophila at least, males and females deal with these competing imperatives in fundamentally different ways, they report July 28 in the journal Nature Communications. “An organism can only do one thing at a time,” said corresponding author ...
