A new study from the University of Central Florida has found strong support that the outgassing of molecules from comets could be the result of the composition from the beginning of our solar system.

Miscanthus is one of the most promising perennial crops for bioenergy production since it is able to produce high yields with a small environmental footprint. This versatile grass has great potential to perform even better, as much less effort has been put into improving it through breeding relative to established commodity crops such as maize or soybean.

As its name implies, the Devil's Hole pupfish lives in a truly hellish environment.

Weeks after Hurricane Fiona hit Puerto Rico, floodwaters have mostly receded in the hard-hit town of Loíza, but mud, debris and collapsed roofs remain. Power has been restored in some areas but is still unstable.

Rotary molecular motors were first created in 1999, in the laboratory of Ben Feringa, Professor of Organic Chemistry at the University of Groningen. These motors are driven by light. For many reasons, it would be good to be able to make these motor molecules visible. The best way to do this is to make them fluoresce. However, combining two light-mediated functions in a single molecule is quite...

In the last few weeks climate change activists have perpetrated various acts of reversible vandalism against famous works of art in public galleries.

Backpackers on working holiday maker visas have been a crucial source of farm labor for decades, alongside smaller numbers of temporary migrants from the Pacific Islands, international students, and Australians.

A new book by Stephanie Sodero of the HCRI explores the intersection between fossil fuel-powered mobility and climate change and how communities and mobility need to be revolutionized in Sodero's homeland of Canada and beyond in the context of climate change.

An Australasian university collaboration has shed new light on marine heatwaves in New Zealand's coastal waters, utilizing the two longest running daily in situ ocean temperature records in the Southern Hemisphere.

A new study comparing the biodiversity of wild mammals in Europe 8,000 years ago with the present has found that more species have been gained than lost on the continent.

The path to peace usually leads through a ceasefire. In an international project, ETH Zurich researchers have shown the conditions under which parties to civil wars are willing to stop fighting—and why they decide to do so.

A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their research has recently been published in Advanced Fiber Materials.

Temperatures in Europe have increased at more than twice the global average over the past 30 years—the highest of any continent in the world. As the warming trend continues, exceptional heat, wildfires, floods and other climate change impacts will affect society, economies and ecosystems, according to a new report from the World Meteorological Organization (WMO).

A good track record in corporate social responsibility (CSR) is not a guarantee that the company will continue to focus on CSR in times of crisis. According to a new study from the University of Vaasa, US companies with a history of high CSR laid off more employees during the COVID-19 pandemic than their peers.

A Brazilian study shows that the number of fires detected in the entire Amazon region between 2003 and 2020 was influenced more by uncontrolled human use of fire than by drought. According to the researchers, burning of vegetation to prepare areas for pasture and deforestation rather than extreme water deficits were the main cause of fire in most years with large numbers of fires.

In September, researchers from California and Denmark were awarded a Nobel Prize in Chemistry for their development of "click" chemistry, a process in which molecules snap together like LEGO, making them a potentially more efficient transportation device in delivering pharmaceuticals to cancer tumors.

Consumers would be willing to buy milk from cows only treated with antibiotics when medically necessary—as long as the price isn't much higher than conventional milk, according to researchers at the College of Veterinary Medicine.

While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.

Topological nontrivial spin textures are intriguing in various physical systems, ranging from high energy to condensed matter physics. The magnetic Skyrmions formed by a swirling magnetization in magnetic materials have potential applications in high-density magnetic information storage and transfer.

Lithium niobite (LN) with an ultra-wide optical transparent window has shown excellent nonlinear, electro-optic, acoustic-optic, piezoelectric, thermoelectric and photorefractive effects. It is an excellent platform for realizing χ(2) nonlinear photonic devices with low power consumption and high efficiency.

Agroforestry—farming with trees—could be pivotal in helping the agricultural sector reach net zero by 2050, according to new research carried out by Cranfield University, which underpins a report by the Woodland Trust.

In order to push the performance of optical systems, aspheric- and freeform surfaces are used in state-of-the-art optic design for correcting aberrations. The production of these complex-shaped surfaces requires measuring the surface deviation from the nominal design. There are a lot of optical measurement methods, such as pointwise and stitching methods.

Jair Bolsonaro has been defeated in the Brazilian election against Luiz Inácio Lula da Silva ("Lula") to the rejoicing of scientists, environmentalists, and human rights activists in Brazil and beyond. What happens in South America's largest country is globally significant since, among other reasons, the country contains most of the world's largest tropical forest.

Small island states are losing their patience with big polluting nations as they suffer the devastating impacts of climate change. Without significant movement at the forthcoming COP27 climate talks in Egypt, a pivotal vote at the next UN general assembly meeting, brought by the tiny Pacific islands of Vanuatu, could open the floodgates to international climate litigation.
