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, […]

ESA Sets Goals for Space Exploration

ESA-funding-reduced

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 […]

A newly published paper describes two ways of reversing autism-like symptoms in a new mouse model of the condition. The scientists published their findings in the journal Nature. Autism spectrum disorder (ASD) can affect up to 1 in 110 people and although a few drugs have shown promise in mouse models, none of them have […]

Self-Assembling Polymer Increases Hard Drive Capacity Fivefold

block-copolymer-dots

Synthetic chemists have designed self-assembling polymers, which require heat in order to rearrange themselves. This technology has the potential of increasing hard drive storage capacity fivefold. The scientists published their findings in the journal Nanotechnology. Currently, information is stored by printing the 1s and 0s of binary data as magnetic dots onto a metal surface. […]

WASP-12 b, A Planet Being Consumed By its Own Sun

Planet devoured by its own sun

A newly published study takes a closer look at WASP-12 b, a planet that is being consumed by its own star. A planet roughly 1.4 times the size of Jupiter is being consumed by its own star behind a shroud thanks to a magnesium veil absorbing all of certain light wavelengths, according to new observations […]
