Milder winters, shrinking habitats and new migratory patterns have changed the birds of the city.

A new NASA mission to Saturn's giant moon, Titan, is due to launch in 2027. When it arrives in the mid-2030s, it will begin a journey of discovery that could bring about a new understanding of the development of life in the universe. This mission, called Dragonfly, will carry an instrument called the Dragonfly Mass Spectrometer (DraMS), designed to help scientists hone in on the chemistry at work on Titan. It may also shed light on the kinds of chemical steps that occurred on Earth that ultimately led to the formation of life, called prebiotic chemistry.

Only a few people have been cured of HIV, but scientists are working to develop cures that could be accessible to more of those infected.

East Asians more likely to develop stomach cancer because of lower alcohol tolerance, new study says

Animal and human remains were excavated from a mustatil, an ancient desert monument believed to have been used for ritual practices in Saudi Arabia.

The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species—known as "good" bacteria—in the gut may enable medical interventions that promote gut and overall human health. In a new study, Yale researchers have uncovered a novel mechanism by which these bacteria colonize the gut.

At least 910 dolphins have washed up on France's Atlantic coast since the start of the winter, an oceanographic institute reported Friday.

Semiconducting single-walled carbon nanotubes (s-SWCNTs) are being used to develop a third generation of optimized shortwave infrared photodetectors that will improve pixel size, weight, power consumption, performance and cost over photodetectors made from traditional materials.

Accurately reconstructing how the parts of a complex molecular are held together knowing only how the molecule distorts and breaks up—this was the challenge taken on by a research team led by SISSA's Cristian Micheletti and recently published on Physical Review Letters. In particular, the scientists studied how a DNA double helix unzips when translocated at high velocity through a nanopore, reconstructing fundamental DNA thermodynamic properties from the sole speed of the process.

The Tibetan Plateau, the highest and largest plateau above sea level, is one of the harshest environments settled by humans. It has a cold and arid environment and its elevation often surpasses 4000 meters above sea level (masl). The plateau covers a wide expanse of Asia—approximately 2.5 million square kilometers—and is home to over 7 million people, primarily belonging to the Tibetan and Sherpa ethnic groups.

The widespread use of persistent, non-biodegradable glass that cannot be naturally eliminated causes long-term environmental hazards and social burdens.

When do we define a piece of nature in the city as a park? And when is something a tree or shrub? It may seem obvious, but in scientific literature the definitions vary quite a bit. That makes comparisons difficult. Environmental scientist Joeri Morpurgo looked at the differences and designed a general classification system for urban green space.

Observations from space show that the rate of sea level rise is increasing. Knowing where and how much rise is happening can help coastal planners prepare for future hazards.

The extraordinary footage of a Russian jet intercepting a US drone over the Black Sea earlier this week demonstrates just how potentially disastrous such encounters outside actual war zones can be.

People with disabilities arguably stand to gain the most from good public transport, but are continually excluded by transport systems that still aren't adapted to their needs as the law requires. One in six people aged 15 and over with disability have difficulty using some or all forms of public transport. One in seven are not able to use public transport at all.

Leading edge technology has uncovered secrets about a world-renowned fossil hoard that could offer vital clues about early life on Earth.

It was 8:15 on a Saturday morning when Woody Goss' phone started buzzing.

Cast your mind back to the spring of 2020, when grocery store shelves sat bare of essential items and ingredients. For birds who live in the forests of Central America, replacement of forest land with coffee plantations essentially "clears out the shelves" of their preferred foods, causing them to shift their diets and habitats to survive.

With more than half of the world's population active on social media networks, user-generated data has proved to be fertile ground for social scientists who study attitudes about the environment and sustainability.

Tens of thousands of years ago, a huge horse species walked, trotted and galloped across the shifting sands of what is today South Africa's Cape south coast.

For more than six decades, Alaska's North Slope has been a focus of intense controversy over oil development and wilderness protection, with no end in sight. Willow field, a 600-million-barrel, US$8 billion oil project recently approved by the Biden administration—to the outrage of environmental and climate activists—is the latest chapter in that long saga.

Abruptly melting ice sheets, the collapse of coral reefs and rainforests: nature is complex—and climate policy must consider physical "tipping points" as well as uncertainties and measurement problems. How can the fight against the greenhouse effect be shaped, given that the world is not as simple as a greenhouse?

British aerospace giant Rolls-Royce said Friday it had secured UK funding to develop small nuclear reactors that could provide power on the Moon.

Quantum computing systems have the potential to outperform classical computers on some tasks, helping to solve complex real-world problems in shorter times. Research teams worldwide have thus been trying to realize this quantum advantage over traditional computers, by creating and testing different quantum systems.

Starting life in captivity can change the wing shape of birds, hindering their chances of surviving migratory flights when they are released into the wild, new research from The Australian National University (ANU) has shown.
