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.

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...


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...

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.

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.

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...
