Eruption of mega-magnetic star lights up nearby galaxy

Science Daily - 24/04/2024
While ESA's satellite INTEGRAL was observing the sky, it spotted a burst of gamma-rays -- high-energy photons -- coming from the nearby galaxy M82. Only a few hours later, ESA's XMM-Newton X-ray space telescope searched for an afterglow from the explosion but found none. An international team realized that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.

A simple 'twist' improves the engine of clean fuel generation

Science Daily - 24/04/2024
Researchers have found a way to super-charge the 'engine' of sustainable fuel generation -- by giving the materials a little twist. The researchers are developing low-cost light-harvesting semiconductors that power devices for converting water into clean hydrogen fuel, using just the power of the sun. These semiconducting materials, known as copper oxides, are cheap, abundant and non-toxic, but their performance does not come close to silicon, which dominates the semiconductor market.

Researchers explain the genomic and developmental basis of the patagium, the thin skin membrane that allows some mammalian species to soar through the air.

Condensed matter physics: Novel one-dimensional superconductor

Science Daily - 24/04/2024
In a significant development in the field of superconductivity, researchers have successfully achieved robust superconductivity in high magnetic fields using a newly created one-dimensional (1D) system. This breakthrough offers a promising pathway to achieving superconductivity in the quantum Hall regime, a longstanding challenge in condensed matter physics.

A novel universal light-based technique to control valley polarization in bulk materials

Science Daily - 24/04/2024
Scientists report a new method that achieves for the first time valley polarization in centrosymmetric bulk materials in a non-material-specific way. This 'universal technique' may have major applications linked to the control and analysis of different properties for 2D and 3D materials, which can in turn enable the advancement of cutting-edge fields such us information processing and quantum computing.

Researching cancer by studying lipids cell by cell

Science Daily - 24/04/2024
A study has sampled single live cancer cells and measured the fatty lipid compounds inside them. The team saw how those cells transformed in response to changes in their environment.

Bioluminescence first evolved in animals at least 540 million years ago

Science Daily - 24/04/2024
Bioluminescence first evolved in animals at least 540 million years ago in a group of marine invertebrates called octocorals, according to the results of a new study. The study focuses on an ancient group of marine invertebrates that includes soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years.

Squids' birthday influences mating

Science Daily - 24/04/2024
The day a male spear squid hatches determines which mating tactic he will use throughout his life, according to new research. Spear squid (Heterololigo bleekeri) that hatch earlier in the season become 'consorts' which fight for mating opportunities. Those which hatch later become 'sneakers,' which use more clandestine mating tactics. Researchers found that the mating tactic determined by the birth date was fixed for the squid's whole life. Understanding how mating tactics are influenced by birth date, and the environmental conditions at that time, can help researchers consider how squid might be affected by climate change and the implications for marine resource management.

Frog species evolved rapidly in response to road salts

Science Daily - 24/04/2024
When we think of evolution, we think of a process that happens over hundreds or thousands of years. In research recently published, a species of frog that has evolved over the course of merely 25 years. The adaptation was spurred on by something many assume is innocuous: salt.

A nontoxic separation process recovers critical minerals from electronic scrap waste.

Chemical tool illuminates pathways used by dopamine, opioids and other neuronal signals

Science Daily - 24/04/2024
Researchers have developed a new tool to better understand how chemicals like dopamine and epinephrine interact with neurons.

Asian monsoon lofts ozone-depleting substances to stratosphere

Science Daily - 24/04/2024
Powerful monsoon winds, strengthened by a warming climate, are lofting unexpectedly large quantities of ozone-depleting substances high into the atmosphere over East Asia, according to new research. The study found that the East Asian Monsoon delivers more than twice the concentration of very short-lived ozone-depleting substances into the upper troposphere and lower stratosphere than previously reported.

World's chocolate supply threatened by devastating virus

Science Daily - 24/04/2024
A rapidly spreading virus threatens the health of the cacao tree and the dried seeds from which chocolate is made, jeopardizing the global supply of the world's most popular treat. Researchers have developed a new strategy: using mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus.

A study suggests timely reporting and investigating of livestock abortions is feasible in rural areas and can provide insights into emerging infectious diseases.

Warming climate is putting more metals into Colorado's mountain streams

Science Daily - 24/04/2024
Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, presenting a concern for ecosystems, downstream water quality and mining remediation, according to a new study. Natural chemical weathering of bedrock is the source of the rising acidity and metals, but the ultimate driver of the trend is climate change, the report found, and the results point to lower stream volumes and exposure of rock once sealed away by ice as the likely causes.
