Georgetown University ecologist Emily Williams first became fascinated with birds not because of their beauty, or their sweet songs. She was riveted by their extraordinary travels.

Transportation infrastructure, such as roads and railway systems, is one of the sectors most threatened by climate change. Extreme weather events—such as flooding, sea level rises and storm surges—repeatedly wreak havoc on transport networks.

Plant functional traits are morphological, physiological or phenological properties that affect plant growth, survival, and reproduction. They hold the promise to explain plant species distribution patterns. However, few studies have linked multiple traits to multiple niche dimensions (i.e., light, water, and nutrients).

Most researchers can draw a line from their current field of study to something in their past that first lit the spark—an engineer who had a knack for fixing things, an economics professor who was always good with numbers.

The COVID-19 pandemic has made more people vulnerable to modern slavery and caused an increase in worker exploitation and child labor around the world, Keele researchers have found.

Researchers at Tohoku University have demonstrated the designability of novel magnets with magic mirror-like characteristics in organic-inorganic hybrid perovskite (OIHP)-type compounds.

Shifts in weather patterns induced by climate change will increase extreme heat and reduce rainfall across major crop growing regions, with impacts on agricultural production. Will this trigger a decline in the supply of calories needed to sustain the world's growing population?

An important element for the protection of biodiversity is the willingness of the public to support restoration efforts. Using a longitudinal survey design with 1,000 respondents each in France, Germany, Norway and Sweden, scientists led by the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) investigated which values, beliefs and norms promote conservation-oriented behavior toward native fishes in rivers. The study shows: Germans have little connection to fish. Rather, the protection... Читать дальше...

The light physical appearance of people with albinism is caused by an inherited condition which results in a lack of melanin. This means people with albinism will have very pale skin, hair, and eyes.

Although scientists often assume that random variations in scientific data fit symmetrical, bell-shaped normal distributions, nature isn't always so tidy. In some cases, a skewed distribution, like the log-normal probability distribution, provides a better fit. Researchers previously found that primary production by ocean phytoplankton and carbon export via particles sinking from the surface are consistent with log-normal distributions.

Using an ultrafast transmission electron microscope, researchers from the Technion—Israel Institute of Technology have, for the first time, recorded the propagation of combined sound and light waves in atomically thin materials.

At night, seven-year-old Miguel likes talking to his father Cesar Rubio about planets and stars. "I try to nurture that," says Rubio, a machinist in Pomona, California, who makes parts for mining and power generation equipment.

A team of researchers from the University of Sydney, the ARC-Plant Protection Research Institute and York University, has found that workers in a species of honeybee found in South Africa reproduce by making near-perfect clones of themselves. In their paper published in Proceedings of the Royal Society B, the group describes their study of the bees and what they learned about them.

Researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) discovered a titanic galactic wind driven by a supermassive black hole 13.1 billion years ago. This is the earliest example yet observed of such a wind to date and is a telltale sign that huge black holes have a profound effect on the growth of galaxies from the very early history of the universe.

Climate change is causing mountain snow to melt more rapidly and glaciers to shrink, but this is making a widely varied impact on water supplies in Asia, a new paper by PSI Senior Scientist Jeffrey Kargel says.

The old double standard lives on.

With Oskar Aszmann and his team at the Department of Plastic, Reconstructive and Aesthetic Surgery, MedUni Vienna has long been regarded as a world leader in bionic limb reconstruction. It was only last year that the world's first fully integrated bionic arm prosthesis was developed at MedUni Vienna. This is ready-to-use and is described as "Plug and Play." Although all bionic aids have so far been used in humans, the technique known as osseointegration (direct skeletal attachment) has now been used for the very first time in a bearded vulture...

A team of scientists at the University of Sussex have for the first time built a modular quantum brain scanner, and used it to record a brain signal. This is the first time a brain signal has been detected using a modular quantum brain sensor anywhere in the world. It's a major milestone for all researchers working on quantum brain imaging technology because modular sensors can be scaled up, like Lego bricks. The team have also connected two sensors like Lego bricks, proving that whole-brain scanning... Читать дальше...

Scientists at the University of Oxford have discovered that classical nova explosions are accompanied by the ejection of jets of oppositely directed hot gas and plasma, and that this persists for years following the nova eruption. Previously, such jets had only been encountered emanating from very different systems such as black holes or newly collapsing stars.

At the center of our Milky Way lies a supermassive black hole (SMBH) called Sagittarius A* (SgrA*). Supermassive black holes reside at the centers of most galaxies, and when they actively accrete gas and dust onto their surrounding hot disks and environments, they radiate across the electromagnetic spectrum. The mass of SgrA* is about 4 million solar masses, much smaller than the billions of solar-mass SMBHs seen in some galaxies. However, it is relatively close by, only about 25,000 light-years distant... Читать дальше...

A body found buried in a ditch by construction workers in the village of Great Casterton, in the east Midlands of England, has shed new light on Roman slavery in Britain. A new analysis of the skeleton and the burial has revealed that the male body was probably that of slave from third century.

Frogs have been around for about 140 million years, since dinosaurs roamed the Earth, and are found in most moist corners of the world. IUCN has assessed 6,340 species of these tailless and smooth-bodied amphibians, and almost one in ten of them are classified as Critically Endangered.

Tourism and the natural environment can be managed in ways that benefit both, new research reports suggest.
