A team led by the Doñana Biological Station and the Geological and Mining Institute of the Spanish National Research Council has reviewed more than 70 studies related to groundwater and the conservation status of one of Europe's most iconic wetlands, Doñana, in southern Spain.

Modern populations of fallow deer possess hidden cultural histories dating back to the Roman Empire, which should be factored into decisions around their management and conservation.

Future technologies rely on phenomena that were previously considered the exclusive domain of theoretical physics or chemistry. For example, the approach to devices with high-density information storage arose when chemists discovered single-molecule magnets—unusual complexes of transition metals and lanthanides. In addition, several lanthanide compounds exhibit temperature-dependent luminescence properties.

Studies of neurological organoids, plant growth, and shifts in body fluids are among the scientific investigations that NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Tracy C. Dyson will help support aboard the International Space Station as part of Expedition 71. The crew members are targeting launch to the space station in February and March.

Several years ago, when Marketa Burnett asked the young Black girls who were part of her research study to talk about what it meant first to be a girl and second a Black girl, they told her the two were indistinguishable.

Since the 1960s, scientists have discovered more than a dozen fundamental particles. They all have fit perfectly into the theoretical framework known as the Standard Model, the best description physicists have of the subatomic world.

A group of scientists led by researchers of from the Khamai Foundation discovered five dazzling new species of eyelash vipers in the jungles and cloud forests of Colombia and Ecuador. This discovery was made official in a study published in Evolutionary Systematics.

When the NBA celebrated the start of its 75th season in fall 2021, it was clear that the 3-point shot adopted by the league in 1979-80 had transformed the sport.

A new study led by University of Massachusetts Amherst engineers paints a clear picture that people in disadvantaged communities in Massachusetts have poorer road quality and are more likely to need to use more fuel for their vehicles as a result.

The contraceptive pill is obviously not intended for fish and frogs. However, the hormones in the pill and other pharmaceuticals that are not completely broken down in sewage treatment plants can affect aquatic organisms.

Employee retention is a key focus for corporations globally, and new research from Edith Cowan University (ECU) has found that leadership style could have a noticeable impact on an employee's working experience.

Data from Norway's National Forest Inventory and from the forest authorities' quality monitoring regime show that over 25% of the forests in Norway are harvested before reaching maturity class 5, the development stage where the forests are normally considered ready for the final harvest.

Legume plants have the unique ability to interact with nitrogen-fixing bacteria in the soil, known as rhizobia. Legumes and rhizobia engage in symbiotic relations upon nitrogen starvation, allowing the plant to thrive without the need for externally supplied nitrogen.

Birds can fly—at least, most of them can. Flightless birds like penguins and ostriches have evolved lifestyles that don't require flight. However, there's a lot that scientists don't know about how the wings and feathers of flightless birds differ from their airborne cousins.

Children's interest in, and competence perceptions of, mathematics are generally quite positive as they begin school, but turn less positive during the first three years. Changes in interest and self-concept are also associated with each other. In other words, if a child's interest fades, so does their competence perception, and vice versa.

For big multinationals that love tax havens, the start of 2024 was not a cause for celebration. On Jan. 1, the European Union, Japan, Canada, and Australia joined other jurisdictions in requiring their largest companies to pay a tax rate of at least 15% on their worldwide profits.

In diamonds (and other semiconducting materials), defects are a quantum sensor's best friend. That's because defects, essentially a jostled arrangement of atoms, sometimes contain electrons with an angular momentum, or spin, that can store and process information. This "spin degree of freedom" can be harnessed for a range of purposes, such as sensing magnetic fields or making a quantum network.

Cumulus clouds over land start to disappear almost instantly during a partial solar eclipse. Until recently, satellite measurements during the eclipse resulted in dark spots in the cloud map, but researchers from TU Delft and KNMI were able to recover the satellite measurements by using a new method.

A new study from Tel Aviv University has discovered that a known practice in information technology can also be applied to chemistry. Researchers found that to enhance the sampling in chemical simulations, all you need to do is stop and restart.

For the first time, researchers have identified what appears to be a network of approximately 20 microbes that universally drive the decomposition of animal flesh. The findings have significant implications for the future of forensic science, including the potential to provide crime scene investigators with a more precise way to determine a body's time of death.

Is it possible to grow tissue in the laboratory, for example to replace injured cartilage? At TU Wien (Vienna), an important step has now been taken toward creating replacement tissue in the lab—using a technique that differs significantly from other methods used around the world. The study is published in Acta Biomaterialia.

You can mend a broken heart this Valentine's Day now that researchers have invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments.

Plastic pollution is a pressing environmental issue, and University of Kentucky Martin-Gatton College of Agriculture, Food and Environment researchers are leading the charge with an innovative solution.

Quantum technology could outperform conventional computers on some advanced optimization and computational tasks. In recent years, physicists have been working to identify new strategies to create quantum systems and promising qubits (i.e., basic units of information in quantum computers).

New research from the Swedish University of Agricultural Sciences and Northumbria University has determined that as warm-loving species expand their ranges under climate change, Britain's landscapes are losing their biological uniqueness.
