A trio of researchers has found evidence of the impact of the Late Antique Little Ice Age on Iceland almost 1,500 years ago. In their paper published in the journal Geology, Christopher Spencer, Thomas Gernon and Ross Mitchell describe…
When an electric current passes through some materials, it generates a voltage perpendicular to the direction in which the current is flowing and of an applied magnetic field. This physical phenomenon, known as the anomalous Hall effect,…
By analyzing the available observational data, astronomers from the Tribhuvan University in Nepal and elsewhere have investigated the properties of a compact dwarf galaxy designated SDSS J134313.15+364457.5 (or J1343+3644 for short). As a…
Neutron star mergers are collisions between neutron stars, the collapsed cores of what were once massive supergiant stars. These mergers are known to generate gravitational waves, energy-carrying waves propagating through a gravitational…
This week, the Curiosity rover found large carbon deposits on Mars, suggesting an ancient carbon cycle. Researchers exploring the domestication of cats believe they may have originally pounced out of Tunisia. And researchers in Michigan…
A team of biologists working at the Naturalis Biodiversity Center, a research museum in the Netherlands, has found evidence of caddisfly larvae using microplastics to build their casings as far back as the 1970s.
A team of astronomers at the Space Telescope Science Institute, working with one colleague from the University of St Andrews' Center for Exoplanet Science and another from the European Southern Observatory, has confirmed the existence of a…
Red roses, the symbol of love, were likely yellow in the past, indicates a large genomic analysis by researchers from Beijing Forestry University, China. Roses of all colors, including white, red, pink, and peach, belong to the genus Rosa,…
Traditionally, magnetic materials have been divided into two main categories: ferromagnets and antiferromagnets. Over the past few years, however, physicists have uncovered the existence of altermagnets, a new type of magnetic material…
Using NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), Indian astronomers have observed an X-ray binary system designated SXP 138. Results of the NuSTAR observations, published March 26 on thearXiv pre-print server, yield important…
Hidden within sphagnum moss, commonly known as peat moss, is an adsorbent material that can help us combat oil spills. A study by researchers from China presents a new bio-based oil adsorbent derived from sphagnum moss that can selectively…
A team of anthropologists, archaeologists and historical specialists affiliated with several institutions in the U.S. and Israel has found that there once existed a coastal settlement in what is now modern-day Israel that was the home to…
The industrially ravaged Gowanus Canal, long regarded as a symbol of urban environmental neglect, is being reimagined through the lens of scientific inquiry as a complex reservoir of microbial life shaped by intense selective pressures.
A study by Dr. Matthew S. Taylor, published in the Journal of Osteoarchaeology, reports on the reanalysis of modified human bones discovered at several prehistoric South Texas archaeological sites.
Astronomers from Swinburne University in Australia and elsewhere have employed the Keck II telescope to investigate the globular cluster system of an ultra-diffuse galaxy designated NGC5846_UDG1. Results of the observations, published…
The detection of dark matter, the elusive type of matter predicted to make up most of the universe's mass, is a long-standing goal in the field of astrophysics. As dark matter does not emit, reflect or absorb light, it cannot be observed…
A pair of physicists at Universidad Nacional de Mar del Plata, in Argentina, have created a computer simulation of the famed Antikythera Mechanism and in so doing have found that manufacturing inaccuracies may have caused the device to jam…
Researchers looking into the origin of domestic cats have long considered that cats likely accompanied early farmers during the Neolithic, spreading through Europe alongside the adoption of agriculture.
Over the past decades, researchers have been trying to develop increasingly advanced and powerful quantum computers, which could outperform classical computers on some tasks. To attain this, they have been trying to identify new ways to…
For many years it was believed that the surface of most, if not all, white dwarfs was made up primarily of hydrogen. But then, two years ago, a white dwarf was spotted by a team of researchers that had a hydrogen surface on one side and a…
An international team of astrophysicists and planetary scientists has discovered a possible link between magnetospheric activity and ionospheric turbulence. In their study published in the journal Physical Review Letters, the group used…
Rising ocean temperatures and lingering industrial toxins are proving deadly for short-beaked common dolphins in UK waters. Researchers led by the Zoological Society of London have drawn a clear connection between environmental stress and…
A trio of environmental scientists at the Mediterranean Institute for Advanced Studies Consejo Superior de Investigaciones Científicas—Universidad de las Islas Baleares, working with a pair of meteorologists from the National Center for…
Indian Institute of Technology Gandhinagar-led research suggests climate change, increased monsoon rainfall and expanded groundwater pumping have driven substantial vegetation growth in the Thar Desert over the past two decades.
An international team of astronomers has performed optical photometric, polarimetric and spectroscopic observations of a cataclysmic variable system known as ASASSN–14dx. Results of the new observations, published April 9 on the arXiv…
A recent study by Dr. Ignacio Montero-Ruiz and his colleagues examined the provenance of ancient copper artifacts discovered on the Island of Ibo off Mozambique's coast. The study, published in Azania: Archaeological Research in Africa,…
Nankai University researchers have found that plant leaves can directly absorb microplastics (MPs) from the atmosphere, leading to a widespread presence of plastic polymers in vegetation. Concentrations of polyethylene terephthalate (PET)…
Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with a mass of at…
A trio of animal physiologists at the University of Tübingen, in Germany, has found that at least one species of crow has the ability to recognize geometric regularity. In their study published in the journal Science Advances, Philipp…
This week, researchers reported a brain circuit linked to the intensity of political behavior. Microbiologists found that the 2018 eruption of the Kīlauea volcano drove a rare, massive summertime phytoplankton bloom, the largest ever…
