Female chickadees living in monogamous mating systems will proactively seek out males that have better cognitive skills than their nest mate, according to new findings.
Paywalls are essential to the financial sustainability of news organizations, yet little is known about how readers respond when they encounter one. Do they subscribe, continue reading free content, look for ways around the paywall or leave the site altogether?
Life on Earth has evolved under an uninterrupted rhythm of day and night. While light provides the energy that powers countless molecular processes, periods of darkness often allow biological systems to reorganize, recover and transform that energy into functional outcomes.
Many quantum effects can be observed only when a small number of particles is studied—individual atoms, molecules or photons, for example, carefully shielded from the rest of the world. But what about macroscopic objects, consisting of an unimaginably large number of particles?
A new study published in the journal Nature Conservation reveals that threatened amphibian species are being inadvertently or illegally sold under incorrect names in digital marketplaces. Using DNA barcoding, researchers discovered that frogs traded online as a widely farmed

A Yale-led team of astronomers has found a third galaxy devoid of dark matter—located alongside the other two in a formation that has never been seen before. Astronomers have followed a faint, cosmic trail of gas to a third galaxy that has no dark matter.
Hot and dry conditions have become synonymous with the risk of extreme wildfires. But a new paper argues that such conditions are not, by themselves, sufficient for blazes, and most warm years do not result in the burning of exceptionally large areas.
When living cells grow, divide or respond to drugs, they give off tiny amounts of heat that offer information about what the cells are doing. But because these heat signals are so vanishingly small, they have traditionally been impossible to measure directly. Researchers in the
Experimental atomic physicists have discovered there is a maximum amount of electrical resistance, or resistivity, that can result from collisions between electrons.
Certain substances can become magnetic when exposed to an external magnetic field. Magnetic susceptibility measures how easily a material can be magnetized. Materials known as organic radicals have been noted to possess anomalously large magnetic susceptibility. However,
Heat waves are arriving sooner and becoming hotter, with the United Kingdom recording May 25 as its hottest day in May since tracking began more than a century ago, only for the record to be broken again the next day. While humans can turn to artificial means of cooling, such
The Dan David Prize will award nine historians and archaeologists with $300,000 to recognize their work and support future research, the foundation announced Tuesday.
Individuals subject to extreme risk protection orders (ERPOs), or "red flag" laws, were significantly less likely to be arrested—including for violent and firearm-related offenses—while the orders were in effect than in the six months before. Strikingly, the drop in arrests did
Using an innovative combination of biochemical experiments and ultra-high-resolution microscopy, a research team at Kiel University has solved the long-standing mystery of how the bacterium B. subtilis regulates its cell division.
Every year, more people in England and Wales are involved in disputes before the civil courts than in the criminal courts. More than 1 million claims a year—for personal injury, debt, housing disrepair, faulty consumer goods or breach of contract, for example—are dealt with in
Genome sequencing has revealed insights into how current-day residents of the Faroe Islands can trace their ancestry to a North Atlantic founder population and how evolutionary forces have shaped their genomes since. The research, published in eLife, uses whole-genome
A University of Melbourne researcher has placed the strongest constraints yet on certain rare decays of subatomic particles, narrowing the window for where new "hidden" particles could be lurking.
We think of atomic clocks as the definitive timekeepers. They are famous for being accurate down to the picosecond. Unfortunately, they are still subject to general relativity, so if you put them on a different planet, they will track time slightly faster or slower than on
A new fluorescent reporter capable of visualizing biologically active iron and oxygen inside living cells at single-cell resolution has been developed, as reported by researchers from Science Tokyo. Using this new tool, they revealed striking differences in the distribution of
An international team of researchers has found plants in the tropics absorb much less carbon dioxide than previous modeling had suggested, which has implications for ecosystem management.
Most of my ecology and evolution undergraduates have never held a pair of binoculars or looked at a bug through a magnifying glass. They don't know how to use a key to identify a plant or insect, let alone why they should bother. They struggle to name common garden birds. They
For women's health providers, the Dobbs decision that rescinded abortion rights wasn't just an abstract political event.
A research team from Tohoku University and Kyocera Corp. has developed a new magneto-optical material—a nanocomposite magnetic garnet film—that can be deposited directly onto silicon substrates while delivering a magneto-optical figure of merit four times higher than
