The first prehistoric wind instruments discovered in the Levant
Although the prehistoric site of Eynan-Mallaha in northern Israel has been thoroughly examined since 1955, it still holds some surprises for scientists. Seven prehistoric wind instruments known as flutes, recently identified by a Franco-Israeli team, are the subject of an article published on 9 June in Scientific Reports.
Researchers demonstrate noise-free communication with structured light
The patterns of light hold tremendous promise for a large encoding alphabet in optical communications, but progress is hindered by their susceptibility to distortion, such as in atmospheric turbulence or in bent optical fiber.
Phonons can be chiral: Study claims to settle the debate
Findings published in Nature settle the dispute: phonons can be chiral. This fundamental concept, discovered using circular X-ray light, sees phonons twisting like a corkscrew through quartz.
Study provides genomic resources to help boost climate resilience of fisheries
Candidate genes that could help fish to tolerate warmer and saltier water have been identified in new research from the Earlham Institute, potentially providing a vital resource to guide breeding programs in freshwater aquaculture.
Campi Flegrei volcano edges closer to possible eruption
The Campi Flegrei volcano in southern Italy has become weaker and more prone to rupturing, making an eruption more likely, according to a new study by researchers at UCL (University College London) and Italy's National Research Institute for Geophysics and Volcanology (INGV).
Why elephants have whiskers on their trunks
A team of zoologists from the Bernstein Center for Computational Neuroscience Berlin, Humboldt-Universität zu Berlin, the Leibniz Institute for Zoo and Wildlife Research and Berlin Zoological Garden has discovered the purpose of whiskers on elephant trunks. In their project, reported in the journal Communications Biology, the group studied elephant trunks and their whiskers in two ways.
KISS method for 2D material preparation: Unlocking new possibilities for materials science
It has almost been 20 years since the establishment of the field of two-dimensional (2D) materials with the discovery of unique properties of graphene, a single, atomically thin layer of graphite. The significance of graphene and its one-of-a-kind properties was recognized as early as 2010 when the Nobel prize in physics was awarded to A. Geim and K. Novoselov for their work on graphene. However,...
Astronomers investigate the properties of a nearby pulsar
Using the XMM-Newton satellite and the Hubble Space Telescope (HST), astronomers have conducted X-ray and near-infrared observations of a nearby middle-aged pulsar known as PSR B1055-52. Results of the observational campaign, published on the arXiv preprint server, deliver essential information regarding the properties of this pulsar.
Searching for new particle: Discovering axions could help answer one of the most puzzling questions in physics
One of the most high-profile mysteries in physics today is what scientists refer to as the "Strong CP Problem." Stemming from the puzzling phenomenon that neutrons do not interact with electric fields despite being made up of quarks—smaller, fundamental particles that carry electric charges—the Strong CP Problem puts into question the Standard Model of physics, or the set of theories...
Smoke from Canadian wildfires detected in Norway
Smoke from Canadian wildfires has been detected thousands of kilometers away in Norway this week, the Scandinavian country's Climate and Environmental Research Institute NILU said on Friday.
Facing unprecedented fire season, Canada confronts logistical challenge
Larger and more powerful wildfires than ever have scorched millions of hectares of Canadian forests and displaced tens of thousands of residents. With so many fires out of control and no relief in sight, the nation is facing a logistical nightmare.
Canada wildfires spark 'ecoterrorist' conspiracy theory
As Canada hurtles towards its worst wildfire season in history, a conspiracy theory has taken off online claiming environmentalists intentionally set some of the blazes.
Social media and duct tape are helping people make DIY air purifiers that filter out wildfire smoke
Social media users are sharing a surprisingly effective way to protect yourself indoors from the toxic wildfire smoke blanketing much of the East Coast: a box fan, four air filters and a whole lot of duct tape.
Philippines evacuates people near Mayon Volcano, where more unrest indicates eruption may be coming
Philippine troops, police and rescue workers began forcibly evacuating residents near Mayon Volcano on Friday as its increasing unrest indicated a violent eruption of one of the country's most active volcanoes is possible within weeks or days.
Ancient herbivore's diet weakened teeth and lead to eventual starvation, suggests study
A team of researchers from the University of Bristol have shed light on the life of the ancient reptile Rhynchosaur, which walked the earth between 250-225 million years ago, before being replaced by the dinosaurs.

Unraveling the role of the NiO electrocatalyst in alcohol electrooxidation reactions
A study led by Dr. Wei Chen, Prof. Yuqin Zou, and Prof. Shuangyin Wang (State Key Laboratory of Chemo/Bio-Sensing and Chemometrics, College of Chemistry and Chemical Engineering, Advanced Catalytic Engineering Research Center of the Ministry of Education, Hunan University) unravels the reaction mechanism of the primary alcohol/vicinal diol electrooxidation reaction on NiO, especially for the...
Generation game: Gene-edited mosquitos to fight malaria
Population-level changes in the genetic make-up of one of the world's deadliest animals could provide a key in the fight against malaria, proponents of a radical new technology argue.
New model offers a way to speed up drug discovery
Huge libraries of drug compounds may hold potential treatments for a variety of diseases, such as cancer or heart disease. Ideally, scientists would like to experimentally test each of these compounds against all possible targets, but doing that kind of screen is prohibitively time-consuming.
Non-police services for domestic abusive victims shown to decrease witness statement provision, but reduce victimisation
Victims of repeat domestic abuse are less likely to provide witness statements to police when they have access to non-police services, according to a study from the University of Surrey.
For pet dogs, 'running with the pack' may be the best prevention to promote healthier living
What exactly makes for a fit Fido? And how does a dog's environment factor into their dog years?
Seaweed farming may help tackle global food insecurity
To help solve hunger and malnutrition while also slowing climate change, some farmers could shift from land to sea, suggests a recent study from the Friedman School of Nutrition Science and Policy at Tufts University. The study was published in Global Food Security.
Most nations get low marks on 'net-zero' climate plans
Nearly all of 35 countries accounting for more than four-fifths of global greenhouse gas emissions got low marks for their net zero plans in a peer-reviewed assessment published Thursday.
Untapping barley's grain yield potential by mitigating floral degeneration
Barley possesses an indeterminate "spike"-type inflorescence that forms basic floral structures, called spikelets, in a distichous pattern along its central axis (termed rachis). Each rachis node in the barley spike produces three (one central and two lateral) spikelets.
How and why NASA gives a name to every spot it studies on Mars
Martian maps are full of monikers recognizing places on Earth, explorers, and even cartoon characters.
Multifunctional self-healing liquid metal hydrogel developed for human-computer interaction
Recently, researchers from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences, led by Prof. Tian Xingyou and Prof. Zhang Xian, along with associate Prof. Yang Yanyu from the College of Materials Science and Engineering at Zhengzhou University, used gallium indium alloy (EGaIn) to initiate the polymerization and serve as flexible fillers to construct liquid...
