Traffic noise makes mating crickets less picky

A new study shows that the mating behaviour of crickets is significantly affected by traffic noise and other man-made sounds—a finding that could have implications for the future success of the species.

Apes, robots and men: The life and death of the first space chimp

On January 31, 1961, an intrepid chimpanzee called Ham was launched on a rocket from Cape Canaveral in the United States, and returned to Earth alive. In this process, he became the first hominin in space.

A full-scale prototype for muon tomography

Each year, billions of tons of goods are transported globally using cargo containers. Currently, there are concerns that this immense volume of traffic could be exploited to transport illicit nuclear materials, with little chance of detection. One promising approach to combating this issue is to measure how goods interact with charged particles named muons—which form naturally as cosmic rays interact with Earth's atmosphere. Studies worldwide have now explored how this technique, named "muon tomography," can be achieved through a variety of detection technologies and reconstruction algorithms. In this article of EPJ Plus, a team headed by Francesco Riggi at the University of Catania, Italy, build on these results to develop a full-scale muon tomograph prototype.

Supersaturation: The barrier between protein folding and misfolding

Correct, or native, protein folding is essential for correct protein function. Protein misfolding can lead to the formation of amyloid fibrils, and amyloidosis, which is implicated in various human neurodegenerative diseases, including Parkinson's, Alzheimer's, and Huntington's diseases. In this study Yuji Goto and colleagues describe, for the first time, a dynamic link between protein folding and misfolding, and the threshold that must be overcome for the formation of amyloid fibrils.

Branches and treetops can reduce greenhouse gas emission from heavy transport by 90%

New research from University of Gävle shows that forest residues can generate large amounts of biofuel, and, in the long run, reduce greenhouse gas emission by 88-94% from heavy transport on Swedish roads.

You can't talk about disaster risk reduction without talking about inequality

The human and environmental cost of climate change is all around us, and on the rise. The UN reports about 90% of all disasters are weather-related, and that weather and climate are major drivers of disaster risk. So it's more important than ever to examine who is bearing the brunt of this change.

800 million people now using 'Asian Englishes' on a regular basis

An estimated 280 million people in India, as well as 280 million in China, regularly speak English. If ASEAN and other Asian countries are included, the tally reaches an astonishing 800 million people now using "Asian Englishes" on a regular basis.

Researchers realize single full field-of-view reconstruction fourier ptychographic microscopy

Fourier ptychographic microscopy (FPM) is a recently developed computational imaging technique, which has high-resolution and wide field-of-view (FOV). However, due to the lower light efficiency of the off-axis LEDs, the exposure time of dark-field images has to be extended to improve the signal-to-noise of dark-field images. In addition, effected by the spherical illumination wavefronts of LEDs, the wavevectors of full-FOV are different.

Image: Hubble spots an interstellar interaction

The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).

Meet the nano-chameleon, a new contender for the title of world's smallest reptile

An international team, led by the Bavarian State Collection of Zoology (ZSM-SNSB), has discovered a minuscule new species of chameleon. The sole known, apparently adult male of the new species has a body size of just 13.5 mm, making it the smallest known male of the roughly 11,500 known non-avian reptiles. A comparison with 51 other chameleon species showed that the new species has exceptionally large genitals. The study was published in the open access journal Scientific Reports.

Pioneering quantum hardware allows for controlling up to thousands of qubits at cryogenic temperatures

Quantum computing offers the promise of solutions to previously unsolvable problems, but in order to deliver on this promise, it will be necessary to preserve and manipulate information that is contained in the most delicate of resources: highly entangled quantum states. One thing that makes this so challenging is that quantum devices must be ensconced in an extreme environment in order to preserve quantum information, but signals must be sent to each qubit in order to manipulate this information—requiring, in essence, an information superhighway into this extreme environment. Both of these problems must, moreover, be solved at a scale far beyond that of present-day quantum device technology.
