A new study reveals the Chicxulub impact crater may have harbored a vast and long-lived hydrothermal system after the catastrophic impact event linked to the extinction of dinosaurs 66 million years ago.

Rochester Institute of Technology scientists have developed a method they believe will help epidemiologists more efficiently predict the spread of the COVID-19 pandemic. Their new study, published in Physica D: Nonlinear Phenomena, outlines a solution to the SIR epidemic model, which is commonly used to predict how many people are susceptible to, infected by, and recovered from viral epidemics.

By studying sewage at a New Haven wastewater treatment facility, a team of Yale researchers has determined that genetic code embedded in feces could be used as an early warning sign of COVID-19 outbreaks.

Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. They were able to compile about 10 times more pictures of merging galaxies than previous studies by using a machine-learning algorithm.

Shark fins recently sampled from markets in China and Hong Kong contained dangerously high levels of mercury.

A dead Asian giant hornet has been found in Washington state, and officials said Friday they were trying to learn if the honey bee predators have established colonies here.

Farmers in Bangladesh achieved significantly higher yields and revenues by growing insect-resistant, genetically engineered eggplant, a new Cornell study has found.

Warming events are increasing in magnitude and severity, threatening many ecosystems worldwide. As the global temperatures continue to climb, it also raises uncertainties as to the relationship, prevalence, and spread of parasites and disease.

The Neolithic lifestyle, including farming, animal domestication and the development of new technologies, emerged in the Near East around 12,000 years ago and contributed profoundly to the modern way of life. The Neolithic spread rapidly across Europe, mainly along the Danube valley and the Mediterranean coastline, reaching the Atlantic coast around 5000-4500 BCE. The existing archaeogenetic data...

Advances in neuroscience research and microscopy: a collaborative project driven by researchers of the Max Perutz Labs Vienna, a joint venture of the University of Vienna and the Medical University of Vienna, and the TU Wien (Vienna) allows researchers to look deep into organs and nervous systems of animals, ranging from squids and worms to fish and salamanders.

Russia's space agency says it will send a team of specialists to South America to investigate the leak of toxic fuel from a Russian rocket stage at the Guiana Space Center.

SpaceX pressed ahead with its second attempt to launch astronauts for NASA—a historic first for a private company—but more stormy weather threatened more delays.

Hurricanes. Earthquakes. COVID-19.

The more people know about when and why behavioral interventions are being used and their effectiveness, the more likely they are to accept their use to change their behavior, according to recent research from Queen Mary University of London and the University of Oxford.

Land use choices can have a significant impact on climate change mitigation and help meet the increased ambition foreseen by the "European Green Deal." It is time to step up efforts to quantify the land sector's carbon emissions and removals. A study, which includes the CMCC Foundation's participation analyzes the EU regulations in force on the subject, which to date still place limits on the...

The world has been experiencing an unprecedented economic downturn due to the COVID-19 pandemic. A significant number of economic activities have shut down, causing contractions in global output, as well as the loss of businesses and family income. Recent evidence shows that millions of people globally lost their jobs and projecting the extent of the impending global economic loss remains a...

A key atomic building block for all living organisms and one of the most abundant elements in the galaxy, nitrogen is an essential part of our ecosystem. But for our ecosystem to function, nitrogen-based compounds must cycle through air, water, and soil in a delicate balance among the other organic chemical drivers of life.

Scientists from the University of Maryland School of Medicine (UMSOM) developed an experimental diagnostic test for COVID-19 that can visually detect the presence of the virus in 10 minutes. It uses a simple assay containing plasmonic gold nanoparticles to detect a color change when the virus is present. The test does not require the use of any advanced laboratory techniques, such as those...

Scientists writing for the journal Invasive Plant Science and Management say several exotic grass species once grown in South Texas for livestock forage and erosion control have expanded from the areas where they were planted and have become invasive. They now are reducing the region's biodiversity and the habitats available for wildlife.

California and nearly two dozen other states on Wednesday filed suit against the Trump administration, arguing that its decision to weaken fuel efficiency standards for cars and trucks puts the public's health at risk and is based on flawed science.

Tree roots have multiple essential functions for their growth and survival. Acquiring nutrients and water from the soil, storing food and anchoring the plant in a substratum are what keep plants alive. In addition, root traits adapt themselves to physical limitation: they grow longer and thinner in dry soils in order to seek faraway water and they stay shorter in compact soils. Thanks to these...

Imagine you're a dog. Your owner is trapped in a box and is crying out for help. Are you aware of his despair? If so, can you set him free? And what's more, do you really want to?

A Bristol academic has achieved a milestone in statistical/mathematical physics by solving a 100-year-old physics problem—the discrete diffusion equation in finite space.

As embryos develop, tissues flow and reorganize dramatically on timescales as brief as minutes. This reorganization includes epithelial tissues that cover outer surfaces and inner linings of organs and blood vessels. As the embryo develops, these tissues often narrow along one axis and extend along a perpendicular axis through cellular movement caused by external or internal forces acting...
