Eyeing echidnas: Study models echidna forelimbs to help shed new light on mammal evolution
These days, mammals can use their forelimbs to swim, jump, fly, climb, dig and just about everything in between, but the question of how all that diversity evolved has remained a vexing one for scientists.
Majority of HIV persistence during ART due to infected cell proliferation
A majority of the HIV-infected cells that persist in HIV-infected individuals even during suppressive antiretroviral therapy (ART) originated from cellular proliferation, not viral replication, according to new research published …
Abell 1033: To boldly go into colliding galaxy clusters
Hidden in a distant galaxy cluster collision are wisps of gas resembling the starship Enterprise—an iconic spaceship from the “Star Trek” franchise.
SpaceX gets nod to put 12,000 satellites in orbit
SpaceX got the green light this week from US authorities to put a constellation of nearly 12,000 satellites into orbit in order to boost cheap, wireless internet access by the 2020s.
New discovery shows glass made from exploding stars
The next time you’re gazing out of the window in search of inspiration, keep in mind the material you’re looking through was forged inside the heart of an exploding ancient star.
Infinite-dimensional symmetry opens up possibility of a new physics—and new particles
The symmetries that govern the world of elementary particles at the most elementary level could be radically different from what has so far been thought. This surprising conclusion emerges from new work published by theoreticians …
Progress in genetic testing of embryos stokes fears of designer babies
ColorUNet: A new deep CNN classification approach to colorization
A team of researchers at Stanford University has recently developed a CNN classification method to colorize grayscale images. The tool they devised, called ColorUNet, draws inspiration from U-Net, a fully convolutional network …
Electric blue thrusters propelling BepiColombo to Mercury
In mid-December, twin discs will begin glowing blue on the underside of a minibus-sized spacecraft in deep space. At that moment Europe and Japan’s BepiColombo mission will have just come a crucial step closer to Mercury.
Solving mazes with single-molecule DNA navigators
The field of intelligent nanorobotics is based on the great promise of molecular devices with information processing capabilities. In a new study that supports the trend of DNA-based information carriers, scientists have …
Half of the world’s annual precipitation falls in just 12 days, new study finds
Currently, half of the world’s measured precipitation that falls in a year falls in just 12 days, according to a new analysis of data collected at weather stations across the globe.

In a historic vote, more than 50 nations unanimously approved an overhaul of the international measurement system that underpins global trade and other human endeavors, uniting Friday behind new definitions for the kilogram …
PNW woodlands will be less vulnerable to drought, fire than Rocky Mountain, Sierra forests
Forests in the Pacific Northwest will be less vulnerable to drought and fire over the next three decades than those in the Rocky Mountains and Sierra Nevada, computer modeling by researchers in Oregon State University’s College …
Sucking your baby’s pacifier may benefit their health
Many parents probably think nothing of sucking on their baby’s pacifier to clean it after it falls to the ground. Turns out, doing so may benefit their child’s health.
Treated superalloys demonstrate unprecedented heat resistance
Researchers at Idaho National Laboratory have discovered how to make “superalloys” even more super, extending useful life by thousands of hours. The discovery could improve materials performance for electrical generators …
Graphene flickers at 400Hz in 2500ppi displays
With virtual reality (VR) sizzling in every electronic fair, there is a need for displays with higher resolution, frame rates and power efficiency. Now, a joint collaboration of researchers from SCALE Nanotech, Graphenea …
Laser technology uncovers medieval secrets locked in Alpine ice core
A new study has found ground-breaking evidence from an ice core in the Swiss-Italian Alps that proves the 7th century switch from gold to silver currencies in western Europe actually occurred a quarter of a century earlier …
