New Images Capture Mount Etna's Massive Eruption From Space
On June 2, Mount Etna erupted, spewing hot lava down its slopes as a massive ash cloud towered above Sicily. Located on the Italian island of Sicily, Europe's highest and most active volcano sent a colossal plume of ash soaring up to 5 kilometres into the sky during the eruption. Meanwhile, a European Space Agency satellite captured the whole thing from space. Copernicus Sentinel-2C snapped dramatic photos of the eruption just minutes after it began, providing a unique perspective on the volcanic activity.
The satellite, launched by the European Commission's Earth observation program in September 2024, captured striking images of Mount Etna's eruption from an altitude of 775 km. The photos reveal a dense ash plume and a pyrocumulus cloud drifting over inland Sicily, as well as active lava flows descending into the Valle del Bove.
"The image here clearly depicts the lava flow and huge plume of smoke and ash. A capture from the Copernicus Sentinel-5P satellite also shows the sulphur dioxide emitted in the plume," ESA wrote while sharing the image.

As per Space.com, ESA's Copernicus Sentinel-5P satellite caught the eruption using its wide swath high-resolution multispectral imager that includes 13 spectral bands for imaging Earth's vegetation and landscape.
The Copernicus satellites provide critical data to experts, enabling them to monitor volcanic activity, assess hazards, support emergency responses, and track long-term landscape changes.
The eruption began at 11:24 am local time on June 2, when increased pressure from hot gases inside Mount Etna led to a partial collapse of one of its craters. This triggered a pyroclastic flow, sending a dense column of ash and smoke kilometres into the atmosphere. Lava flowed in three directions but began to cool down. Pyroclastic flows are highly hazardous, reaching temperatures of up to 1,000°C and travelling at speeds of around 60 miles per hour.

Notably, there hadn't been an eruption from Etna of this magnitude since 2014, according to the National Institute of Geophysics and Volcanology Observatory. The National Institute of Geophysics and Volcanology (INGV) had noted Mount Etna was experiencing "intense and almost continuous" strombolian explosions. According to the latest statement by INGV, the eruption activity has ceased.

Next Pandemic Soon? Bat Viruses In China Show Covid-Like Threat, Scientists Warn
Last Updated: Like SARS-CoV-2- the virus behind Covid-19- these bat viruses use spike proteins to invade host cells by attaching to the ACE2 receptor. A newly published study in Nature Communications raised alarm as it showed that a little-known group of bat viruses could be just a single mutation away from infecting humans. The research, conducted by teams from Washington State University, Caltech and the University of North Carolina, zeroes in on HKU5 viruses—a subgroup within the merbecoviruses, which are relatives of MERS-CoV, the deadly coronavirus that emerged in 2012 and carries a fatality rate of around 34%. 'HKU5 viruses haven't been studied much, but our research shows they have the machinery to infect cells. In fact, they might be only a single step away from being able to infect humans," Dr. Michael Letko, the study's lead author and a virologist at Washington State University, said. The Spike Protein Problem Like SARS-CoV-2- the virus behind Covid-19- these bat viruses use spike proteins to invade host cells by attaching to the ACE2 receptor. Currently, HKU5 viruses bind to ACE2 only in bats. But scientists warn that a tiny genetic change could allow them to jump to humans. Supporting this concern, some HKU5 variants have already been seen infecting minks in China- proof that they can jump between species. Adding to the urgency, researchers used AlphaFold 3, a cutting-edge AI tool, to model how these spike proteins could evolve. The software simulated potential mutations and interactions with human cells in minutes, accurately matching traditional lab results. Scientists' Warning For The Future The new findings align with earlier research led by China's renowned virologist Shi Zhengli- often dubbed the 'batwoman." Her team had found that HKU5-CoV-2, a variant in this group, was capable of infecting human cells in test tubes and lab models of the human respiratory and digestive systems. The researchers also identified potential monoclonal antibodies and antivirals that could target the virus if it crosses over. Dr. Letko stressed, 'There's no need to panic, but there is every reason to prepare."

Just a small mutation away? New China-linked virus could be next big threat
A group of bat viruses closely related to the deadly Middle East respiratory syndrome coronavirus ( MERS-CoV ) — and first identified in bats in China — may be just one small mutation away from infecting humans and potentially triggering the next global pandemic, scientists have warned. In a recent study published in Nature Communications, researchers revealed that a specific subgroup of these viruses, known as HKU5, shows worrying signs of being able to jump species, raising alarms about a possible spillover from animals to people. The study, led by researchers from Washington State University (WSU), in collaboration with the California Institute of Technology and the University of North Carolina, focused on a lesser-known subset of coronaviruses called merbecoviruses—the same family that includes MERS, which has a human fatality rate of approximately 34%. While most merbecoviruses appear unlikely to infect humans directly, one particular group, known as HKU5, is showing troubling potential. 'Merbecoviruses — and HKU5 viruses in particular — really hadn't been looked at much, but our study shows how these viruses infect cells,' said Michael Letko, virologist at WSU's College of Veterinary Medicine. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' Using virus-like particles engineered to contain only the receptor-binding portion of the virus's spike protein, the researchers demonstrated that HKU5 viruses can already use the ACE2 receptor—the same receptor used by SARS-CoV-2, the virus that causes COVID-19. However, for now, HKU5 viruses bind more efficiently to bat ACE2 and do not infect human cells effectively—yet. Live Events The viruses were originally discovered in Japanese house bats (Pipistrellus abramus), but recent studies suggest some HKU5 strains may already be jumping to intermediate hosts such as minks, a key step that could lead to human infections. 'These viruses are so closely related to MERS, so we have to be concerned if they ever infect humans,' Letko cautioned. 'While there's no evidence they've crossed into people yet, the potential is there — and that makes them worth watching.' The team also deployed artificial intelligence tools, such as AlphaFold 3, to simulate how HKU5's spike protein interacts with the ACE2 receptor at a molecular level. The AI-generated models matched results produced by traditional lab methods, but in a fraction of the time, significantly speeding up the understanding of how the virus might evolve and evade immune defenses.

IIT Guwahati harnesses clay sedimentation to identify and measure coronavirus
Live Events (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel Indian Institute of Technology (IIT) Guwahati researchers have developed a novel method for detecting and measuring the amount of SARS-CoV-2, the virus that causes innovative approach is based on how quickly a clay-virus-electrolyte mixture settles; a process commonly known as sedimentation, offering a simple and affordable alternative to the complex and expensive methods currently in use for virus findings of this research have been published in the prestigious peer-reviewed journal, Applied Clay Science, in a paper co-authored by Prof. T.V. Bharat, Department of Civil Engineering, and Prof. Sachin Kumar, Department of Biosciences and Bioengineering, along with research scholars Dr. Himanshu Yadav and Deepa Mehta, at IIT Guwahati Posing a threat to human lives globally, the COVID-19 pandemic revealed a critical gap in how we detect and track viral infections. Current methods, such as Polymerase Chain Reaction (PCR), are highly sensitive but time consuming and require heavy equipment. Similarly, the antigen testing is fast but lacks accuracy, while antibody testing is used after the infection has occurred, highlighting limitations at various levels. Additionally, many of these methods are not practical in resource-limited settings or during large-scale address these gaps, Prof. T.V. Bharat, Department of Civil Engineering, IIT Guwahati, along with his research team has used Bentonite clay, a clay well known for its ability to absorb pollutants and heavy metals due to its unique chemical structure in collaboration with Prof. Sachin Kumar, Department of Biosciences and Bioengineering. Previous studies have shown that clay particles can bind with viruses and bacteriophages, making it a promising material for virus research team focused on how Bentonite clay interacts with virus particles in a salt environment. The research team found that a Coronavirus surrogate and Infectious Bronchitis Virus (IBV) bind to the negatively charged clay surfaces at a controlled room temperature and a neutral pH of T.V. Bharat said, 'Imagine a world where detecting viruses is as simple as watching sand settle in is the breakthrough we have achieved! Our new method uses clay to quickly identify and measure viruses, like the coronavirus. By observing how the clay settles in a solution, we can determine if a virus is present and how much of it there innovative approach offers a faster, more affordable, and accurate alternative to current methods, paving the way for better disease monitoring and treatment strategies, especially during pandemics, this study is in continuation with our recent studies published in prestigious journals like Langmuir in developing exclusive biomedical waste facilities for disposing pathogenic waste sponsored by Department of Science and Technology, Government of India.'The research team validated their findings using established virus-detection methods including plaque assay for a coronavirus surrogate and RT-PCR for IBV. The developed technique produced accurate results in comparison to the standard detection methods, reinforcing its the method can be extended to detect other viruses such as the Newcastle Disease Virus (NDV), which affects poultry and causes major losses in the farming development holds great promise for improving how viral outbreaks are monitored and controlled, especially in regions where expensive lab equipment and trained personnel are not readily available. With further refinement, the method could be adapted for use in field kits or simple laboratory setups, making virus detection more accessible and efficient in future public health the next step, the research team is planning to collaborate with industry partners with medical facilities for clinical trials for SARS-Cov-2 and other viruses. By partnering with industry, the research team hopes to leverage the resources and expertise necessary to conduct robust clinical trials and ultimately contribute to the global effort to combat viral infections.
