Summary: Concerns about the survivability of American aircraft carriers in a potential conflict with China are rising.

-Despite significant investments in the world’s finest aircraft carrier fleet, advancements in submarine and missile technology are rendering these vessels increasingly vulnerable. An exercise demonstrated a French submarine’s ability to strike a US carrier, highlighting this vulnerability.

-As the margin for error narrows, some suggest the US should consider alternative naval strategies, focusing on submarines and smaller, more agile surface vessels. This shift could enhance offensive flexibility and reduce costs but would sacrifice the unique airpower projection capability of aircraft carriers.

Rooftop panels can provide electricity during blackouts and bring Puerto Rico closer to its clean energy goals. Esther Frances/Medill News Service

The coastal communities of Guayama and Salinas in southern Puerto Rico feature acres of vibrant green farmland, and a rich, biodiverse estuary, the protected Jobos Bay, which stretches between the neighboring townships. But this would-be tropical paradise is also the home of both a 52-year-old oil-fired power plant and a 22-year-old coal-fired power plant, which local residents say contaminate their drinking water and air, and harm people’s health.

“It’s a classic sacrifice zone,” said Ruth Santiago, a lawyer and community activist who has fought against environmental injustice in Puerto Rico for more than 20 years. “A friend calls this ‘the beautiful place with serious problems.’”

Like many companies, Unilever—the fast-moving consumer goods company with brands like Dove, Persil and Ben & Jerry’s under its umbrella—has turned to additive manufacturing for its prototyping needs. However, rather than print prototypes of its product packaging directly, it has taken an alternative route, leveraging SLA 3D printing to produce blow molding tools. This approach, which it has taken in partnership with packaging manufacturer Serioplast and Formlabs, has dramatically cut product development cycles for new plastic bottle packaging and tooling costs.

Prior to this new prototyping method, Serioplast would 3D print packaging prototypes directly or order metal tooling for blow molding prototyping. Both these process had their limitations: directly 3D printed prototypes could not match the transparency or feel of the final product, and metal tooling for blow molding prototypes came with long lead times and high costs. As Flavio Migliarelli, R&D Design Manager at Serioplast, said: “We have to wait six to 12 weeks before we can give a client the real sample, so we’re wasting so many weeks just to try a new bottle design. Sometimes it’s demanding and frustrating because maybe you have to start again.”

Japan has sent a defense official to the U.S. Navy to leverage on its experience for the development of a railgun, which uses electromagnetic force to fire bullets at high speeds, government sources said Tuesday.

The dispatch of the official from the Acquisition, Technology and Logistics Agency is aimed at absorbing the know-how of the United States, which long researched railguns, to put the weapon into practical use as soon as possible.

The Defense Ministry-affiliated agency began the development of a railgun in fiscal 2016 and conducted the world’s first offshore shooting test onboard a Maritime Self-Defense Force vessel last year.

The SDF hopes that railguns, which cost less than conventional firearms that use gunpowder and whose projectiles are harder to intercept, will become a “game changer” that will change the strategic environment of warfare.

About 6,800 years ago, a “mayor” was buried with a wealth of food and riches, including a halved boar’s tooth, according to archaeologists who found the rare burial in southern Germany.

The mayor’s Middle Neolithic remains were found near the Bavarian town of Eichendorf, close to Munich and Germany’s southeastern borders with Austria and the Czech Republic. According to the local government of Bavaria’s Dingolfing-Landau district, the discovery was made last week by district archaeologists excavating at the village of Exing, about 1 mile (1.6 kilometers) to the west.

The person in the grave was buried with food and drink for the afterlife; dyes for body painting; a stone ax and a stone adze; and a boar’s tooth split in two.

As FPV drones become more prevalent and sophisticated, armed forces must continuously adapt to maintain their strategic advantage, reflecting the evolving dynamics of modern warfare. | Image:Chinamil

Beijing: China has recently showcased video footage of its People’s Liberation Army (PLA) training to counter first-person view (FPV) drones. The footage highlights the growing necessity for military forces worldwide to develop strategies against these munitions. FPV drone capabilities were rapidly advanced during the war in Ukraine, where they have become a critical element on the frontlines. This technological proliferation has now reached other global hotspots, prompting armed forces, including the U.S. military, to adapt through training and adoption of FPV drones.

In a significant move, 104 out of 120 members of the Israeli Knesset have signed a petition condemning the International Criminal Court’s (ICC) decision to issue arrest warrants for Prime Minister Benjamin Netanyahu and Defense Minister Yoav Gallant.

The petition, titled “A Clear Expression Against Anti-Semitism,” is part of a broader international campaign Israel is leading to pressure the court into reversing its decision.

The petition did not gain support from Arab members of the Knesset or members of the Labor Party.

Meanwhile, Netanyahu is actively holding meetings to push for the retraction of the ICC’s decision, bolstered by those protesting the comparison between him and Hamas leaders, as well as between Israel and Hamas.

Concern is rising in Australia about the global outbreak of bird flu.

Today in Victoria, the Government has advised preliminary tests have confirmed the presence of avian influenza on an egg farm near Meredith, following an investigation of poultry deaths. The farm has been placed under quarantine.

This comes after yesterday’s announcement by the Victorian Department of Health that a child had made a full recovery after contracting the H5N1 virus overseas.

The egg farm preliminary results indicate that it is not the much feared highly pathogenic avian influenza (HPAI) A H5N1 virus clade 2.3.4.4b, according to a statement made by the Australian Government Department of Agriculture, Fisheries and Forestry.

In an interview with The Verge’s Nilay Patel, Alphabet and Google CEO Sundar Pichai discussed AI-powered search, a major topic at the founder’s recent Google I/O developer conference.

At the event, Google announced a slew of new AI tools and models: Ask Photos, AI Agents, Project Astra, Gemini 1.5 Pro and Gemini 1.5 Flash, Nano, and AI Teammate, to name a few.

The most visible announcement for regular people is probably the addition of AI Overviews to Google Search. You’ve probably noticed that when you search anything on Google, an “AI Overview” will pop up, showing you an overview of the answer to your question using AI. Google is answering the question for you, making clicking links to other websites less necessary. It’s changing how web traffic might be traveled — which has many people freaked out. Pichai, of course, said there’s no cause for concern.

ANKARA — Turkey will observe one-day of national mourning after the helicopter crash Sunday that killed Iranian President Ebrahim Raisi  along with seven others, including the country’s foreign minister, Hossein Amirabdollahian.

Speaking after a cabinet meeting in Ankara on Monday, Turkish President Recep Tayyip Erdogan said the day of collective mourning aims to “share the deep pain experienced by the Iranian people.” Erdogan added that he had conveyed his condolences to Iran’s acting president, Mohammad Mokhber, during a phone call earlier in the day.

“We contacted the Iranian authorities and mobilized all our resources to contribute to the search and rescue efforts after the crash,” Erdogan said, adding, “We will continue to act in the same spirit.”

Eco-friendly and affordable battery for low-income countries

A new battery made from zinc and lignin, an organic polymer found in the tissues of most plants, has been developed as a cheap and sustainable battery solution for countries where access to electricity is limited.

“While lithium-ion batteries are useful when handled correctly, they can be explosive, challenging to recycle, and problematic in terms of environmental and human rights issues when specific elements like cobalt are extracted,” says Ziyauddin Khan, a researcher at the Laboratory of Organic Electronics at Linköping University, Sweden.

“Therefore, our sustainable battery offers a promising alternative where energy density is not critical.”

The battery’s energy density is comparable to lead-acid batteries, it can be used for more than 8,000 cycles while maintaining about 80% of its performance and retains its charge for approximately 1 week.

If you ask most “regular people,” they would likely admit that wrapping their heads around how far away things actually are in space is a bit of a stretch.

I know that’s true for me.

So, it almost seems impossible that NASA would be able to receive a message from 140 million miles out.

The Psyche mission was dispatched to study a strange asteroid and for NASA to test a new communication system.

It doesn’t use radio waves but an infrared laser, and so far, has not been successfully tested from such a long way.

The US National Institute of Allergy and Infectious Diseases has started enrolling volunteers at Duke University in North Carolina to test its experimental mRNA-LNP vaccine against seasonal influenza, one of several universal influenza vaccine candidates now in the pipeline. Another clinical trial has begun at the US National Institutes of Health’s Clinical Centre in Maryland.

Influenza kills up to 650,000 people around the world each year.

Ninety-nine percent of deaths in children under five years of age in developing countries are due to influenza-related infections, according to the World Health Organization.

The current crop of influenza vaccines has limitations in effectively combating the billion cases of seasonal influenza each year as they provide immunity against only one specific existing strain or mutation. The propensity of flu viruses to mutate into new strains means vaccines must be continuously monitored and reformulated each year.

A robot just performed microsurgery on a corn kernel, which could change the game for precision surgeries.

Sony has unveiled a prototype of a microsurgery assistance robot which can support surgeons operating on extremely small tissues, nerves, and veins.

The compact creation includes a miniature automatic instrument exchange, designed to reduce the number of interruptions and delays during surgery. The robot’s precision control is further boosted by a lightweight, highly sensitive control device which reflects the delicate movements of human fingertips.

The prototype is also equipped with 1.3-type 4K OLED Microdisplays, that let operators view high-definition images of the targeted area, and closely monitor movement of surgical instruments.

The prototype, tested by Aichi Medical University in Japan, is still at development stage and cannot yet be sold or offered, but Sony hopes that in the future, it can will improve microsurgery accuracy and effectiveness and provide assistance amid staff shortages currently faced by healthcare systems around the globe.

Many of the world’s militaries employ drones for various purposes, but regardless on where they are deployed on this planet, and by whom, the vast majority of the big, professional drones used for surveillance and strikes are made in the U.S.A. And Europe doesn’t like that, so not long ago it set out to create something called the Eurodrone.

The Eurodrone program, which was announced about a year ago, is a collaborative effort between European aviation companies Airbus, Dassault, Safran, and Leonardo, and aims to deliver an uncrewed aerial platform that can be used for intelligence, surveillance, target acquisition, and reconnaissance (ISTAR) missions.The Old Continent makes no secret of the fact it wants to “ensure European sovereignty and independence in this critical segment of unmanned long endurance ISTAR capability,” especially given how it is there where the largest conflict between developed nations since World War II is raging.
