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 […]

Astronomers Find Hydrocarbon in the Horsehead Nebula

Horsehead Nebula in the Orion constellation

Scientists have discovered l-C3H+ hydrocarbon in the interstellar medium for the first time, finding this molecule in the Horsehead Nebula in the Constellation of Orion. The results of their study are published in the journal Astronomy & Astrophysics. What sounds like science fiction is actually reality: using the 30m-telescope of the Institute for Radio Astronomy […]

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 […]

Experiment Using Photons Could Detect Quantum-Scale Black Holes

quantum-gravity-granularity-space

A new tabletop experiment using a single photon was proposed to show whether space-time is made up of indivisible units. Space isn’t smooth, and physicists think that on the quantum scale, it is composed of indivisible subunits, like the dots of a pointillist drawing. This pixelated landscape is thought to be populated by black holes, […]

At a recent meeting in Naples, Italy, EU ministers have agreed to give the European Space Agency (ESA) €10.1 billion ($13 billion) over the next several years, which is less than the total €12 billion that was considered at the beginning of the meeting. The ministers were able to resolve issues and strike deals on […]

Study Shows Dwarf Planet Makemake Lacks Atmosphere

dwarf planet Makemak

Scientists detail the dwarf planet Makemake in a new study, measuring its density for the first time and finding out that it is not surrounded by a significant atmosphere. Astronomers have used three telescopes at ESO’s observatories in Chile to observe the dwarf planet Makemake as it drifted in front of a distant star and […]

New Study Questions the Benefits of Mammograms

mammography-scan

Mammography is routinely used to screen healthy women for breast cancer, and its use has led to the widespread detection and treatment of tumors that would have never caused any symptoms, according to a new study published in the New England Journal of Medicine. The study examined the effects of mammography screens on breast-cancer incidence […]
