A New Subclass of Extra-Solar Planets Discovered

three exceptionally large extra-solar planets, dubbed highly inflated Jupiters

Using the HATNet telescopes, CfA astronomers and colleagues discovered three new hot Jupiters and identified a new subclass of extra-solar planets, dubbed “highly inflated Jupiters.” There are currently 851 confirmed extra-solar planets. Of these, 289 were detected because their orbits (as seen from Earth) take them across the face of their host star, dimming the […]

Cyber-Attacks Could Be Thwarted By CPU Symbiotes

printer-graveyard

Targets for hackers are becoming more widespread. The chips running car engines, routers that form the Internet’s backbone, power plants, and rail lines are all at risk because they can link to computers. Computer scientists are now devising guardians called symbiotes, which could run on embedded computers regardless of the operating system. This could help […]

High-Energy Physicists Set New Record for Data Transfer

high-energy-information-flow

Physicists at the California Institute of Technology have set a new record for data network data transfer speeds. The international team of high-energy physicists, computer scientists and network engineers achieved a rate of 339 gigabits per second (Gbps), which is equivalent to four million gigabytes per day, roughly doubling last year’s record. The scientists presented […]

Exploding Star Could Shed New Light on the Nature of Dark Energy

a connection between white dwarf stars that fail to completely detonate and a class of oddly dim supernovae

An international team of scientists has conclusively demonstrated a connection between white dwarf stars that fail to completely detonate and a class of oddly dim supernovae. Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds—one that could nonetheless throw new light on the mysterious nature of […]

High-Speed Video Helps Scientists Understand Hummingbird Pollination

anna-hummingbird-flight

Hummingbirds are part of the family Trochilidae and are among the smallest birds on the planet, with most species measuring between 7.5 to 13 cm. Now, a new high-speed video has helped scientists understand why hummingbirds always pollinate flowers that hang upside down. The scientists published their findings in the journal Functional Ecology. Hummingbirds are […]

Bats Tune Frequency of Echolocation to Change Field Perception

Bats Tune Frequency of Echolocation

Bats can broaden and narrow their visual field by modulating the frequency of their vocalizations they use to navigate and find prey. The scientists published their findings in the journal Nature. Bats find their way through the depths of night by emitting sonar signal and using the return echoes to create a map of their […]

Katydid Ears Have Structures Similar to Mammalian Ones

copiphora-gorgonensis-katydid-ear

Katydid ears have evolved components resembling those of human ears, on a smaller scale. This is an example of convergent evolution. The scientists published their findings in the journal Science. Katydids are part of the family Tettigoniidae, which encompasses more than 6,400 species. A kind of rainforest katydid has ears that are remarkably similar to […]

Slowing Cargo Ships Results in Major Reductions in Pollution

cargo-ship-hyundai

A new study indicates that slowing down vessels near coastlines by 10 to 15 miles per hour can dramatically reduce air pollution from the ships. However, only a few US ports have initiated efforts to apply this. The scientists published their findings in the journal Environmental Science and Technology. A speed limit of 14 mph, […]

At Least a Third of All Marine Species are Still Unknown

ocean-species-marine

The most comprehensive assessment of ocean life has revealed that one third to two thirds of all species are still unknown to science. The scientists published their findings in the journal Current Biology. There were fewer than 1 million marine species, including 226,000 species that had been described by science and 72,000 in collections awaiting […]
