The ocean absorbed more heat last year than in any year since modern measurements began around 1960, according to a new analysis published in the journal Advances in Atmospheric Science. The world’s oceans absorb more than 90% of the excess heat trapped in the Earth’s atmosphere due to greenhouse gas emissions. As heat accumulates in the atmosphere, so does the heat stored in the oceans, making ocean heat a reliable indicator of long-term climate change.Ocean temperatures influence the frequency and intensity of ocean heatwaves, alter atmospheric circulation, and govern global precipitation patterns. you may like Scientists measure ocean heat in…
Ravie LakshmananJan 19, 2026Hacking News / Cybersecurity In cybersecurity, the line between a normal update and a serious incident keeps getting thinner. Systems that once felt reliable are now under pressure from constant change. New AI tools, connected devices, and automated systems quietly create more ways in, often faster than security teams can react. This week’s stories show how easily a small mistake or hidden service can turn into a real break-in. Behind the headlines, the pattern is clear. Automation is being used against the people who built it. Attackers reuse existing systems instead of building new ones. They move…
European folk healers in the 16th century left their manuals smeared with ingredients and fingerprints as they developed treatments for minor illnesses. Researchers are now studying the chemical traces left behind by Renaissance people to understand how they experimented with new treatments.Two German medical books, How to Cure and Eliminate All Sufferings and Diseases of the Human Body and A Handy and Essential Little Medical Book for the Common Man, were published in 1531 by ophthalmologist Bartholomeus Vogtell. His recipe books, which systematically collected common ailments such as hair loss and bad breath, quickly became Renaissance family medicine bestsellers.Some of…
Just a few years ago, the cloud was touted as the “magic pill” for any cyber threat or performance issue. Many were lured by the “always-on” dream, trading granular control for the convenience of managed services. In recent years, many of us have learned (often the hard way) that public cloud service providers are not immune to attacks and SaaS downtime, hiding behind the Shared Responsibility cushion. To stay operational, competitive, and resilient in today’s threat landscape, teams must move beyond the dependency on SaaS providers and understand what cyber resilience really means. The Myth of DevOps SaaS Resilience In…
The European Space Agency (ESA) has helped Astroscale UK spearhead a cutting-edge project that could redefine the way satellites are kept in orbit. Under the £350,000 Phase A contract, Astroscale will lead the design of the In-Orbit Retrofit and Upgrade Service (IRUS), a mission concept aimed at extending the lifetime of satellites, enabling repairs and integrating upgrades without returning to Earth. The initiative highlights Europe’s increasing focus on space sustainability and on-orbit debris risk mitigation, and sets the stage for the next generation of on-orbit servicing technology. Commenting on the funding, Nick Shave, managing director of Astroscale UK, said: “Astroscale…
Ravi LakshmananJanuary 19, 2026Hardware security/vulnerabilities A team of academics from Germany’s CISPA Helmholtz Center for Information Security has revealed details of a new hardware vulnerability affecting AMD processors. The security flaw, codenamed StackWarp, could allow a malicious attacker with privileged control over a host server to execute malicious code within a Confidential Virtual Machine (CVM), potentially compromising the integrity guarantees provided by AMD Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP). Affects AMD Zen 1 to Zen 5 processors. “In the context of SEV-SNP, this flaw allows malicious VMs to [virtual machine] Researchers Ruiyi Zhang, Tristan Hornetz, Daniel Weber, Fabian…
simple factsName: Nebula Sky DiscWhat is it: Bronze disc with gold accentsBirthplace: Nebra, GermanyCreated: From around 1800 BC to around 1600 BCThe Nebula Sky Disc was discovered in 1999 among a pile of artifacts that metal detectors illegally excavated from an ancient religious site in the hills near Nebula, a town in the German state of Saxony-Anhalt. After police recovered the disc in 2002, archaeologists studied the unique object and found it to be up to 3,800 years old, making it the world’s oldest depiction of an astronomical phenomenon. (The next oldest is a star map on the ceiling of…
On January 17, 2026, the High Seas Convention officially entered into force, ushering in a new era for the protection and sustainable use of the world’s oceans. The Convention, officially called the Convention on Biological Diversity Beyond National Jurisdiction (BBNJ), has been hailed as one of the most important achievements in international ocean policy in recent decades. The High Seas Treaty covers areas beyond national jurisdiction and establishes common rules for nearly half of the Earth’s surface and an estimated 95% of its ocean volume. Long governed by fragmented regulations, these vast oceans are home to the largest ecosystems on…
The UK Government will be distributing Jess’s Rules posters to all GP surgery facilities in England to remind them of their commitment to life-saving patient safety. Jess’s Rules posters will be distributed to all GP surgeries in the UK from this week, demonstrating our commitment to safety to GPs, primary care staff and patients in thousands of consulting rooms. The rules require GPs to approach patients with “fresh eyes” and reconsider if they are unable to provide a patient with a solid diagnosis or their symptoms worsen after three visits. What are Jess’s rules? The initiative, announced in September 2025,…
Astronomers have revealed the clearest images yet of the area around a black hole from the James Webb Space Telescope (JWST). This spectacular view could help solve a decades-old mystery, overturning long-held beliefs about the universe’s most extreme objects.Since the 1990s, astronomers have observed interesting brightness in infrared wavelengths around active supermassive black holes (SMBHs) at the centers of several galaxies. Previously, they thought these excess infrared emissions were due to outflows, streams of superheated material spewed out of the black hole.But in a new study published in the journal Nature Communications on January 13, an international team of researchers…
