    Doubts about women in combat don't stand up to history

    Germany has unveiled plans to introduce voluntary military service. From January 2026, all 18-year-old men will be required to complete a questionnaire asking if they are interested and willing to join the armed forces. Women will not be required to fill out this form.

    How bubbles may speed up CO₂ uptake by the ocean

    A new study provides evidence that the ocean may have absorbed as much as 15% (0.3–0.4 Pg C yr-1) more CO2 than previously thought, requiring a re-think of future CO2 flux assessments and global climate models.

    Cool satellites and flexible electronics: Thin interlayers strengthen flexible composite materials

    The picture that pops up before our inner eye when we hear the word "satellite" is probably this: Two extended solar "wings" and a compact body wrapped in foil with a golden or silvery shimmer. Researchers at Empa's Mechanics of Materials and Nanostructures laboratory in Thun are now working to improve this foil. As its widespread use indicates, the material is crucial for satellites and space probes. It is known as multilayer insulation, or superinsulation, and consists of several layers of a robust polymer coated with a thin layer of metal, usually aluminum. The coated film can also be encountered on Earth, for example in the form of survival blankets.

    Teenagers are preparing for the jobs of 25 years ago, and schools are missing the AI revolution

    The government has recently released its national youth strategy, which promises better career advice for young people in England. It's sorely needed: for teenagers today, the future of work probably feels more like a moving target than a destination. Barely three years after ChatGPT went mainstream, the labor market has already shifted under young people's feet.

    There are about 15,000 satellites orbiting Earth. Most of them, like the International Space Station and the Hubble Telescope, reside in low Earth orbit, or LEO, which tops out at about 1,200 miles (2,000 kilometers) above Earth's surface.

    Two superpowers, one playbook: Why Chinese and US bureaucrats think and act alike

    The year 2025 has not been a great one for U.S.-Chinese relations. Tit-for-tat tariffs and the scramble over rare earth elements has dampened economic relations between the world's two leading economies. Meanwhile, territorial disputes between China and American allies in the Indo-Pacific region have further deepened the intensifying military rivalry.

    The trouble with idioms: How they can leave even fluent English speakers behind

    Being a linguist—and someone who has tried to learn several languages (including English) in addition to my mother tongue (Flemish Dutch)—I have an annoying habit: instead of paying attention to what people are saying, I often get distracted by how they are saying it. The other day, this happened again in a meeting with colleagues.

    Is your dog or cat getting old? These simple gestures could help them live longer and happier lives

    Geriatric veterinary care is in great shape, with dogs and cats living on average 11.3 years, according to French data. Our knowledge of how to accompany them in later life is expanding fast. We now know that simple changes can do wonders for an old cat or dog's comfort and quality of life. The main trick is for pet owners not to stand by idly as their four-legged companions age.

    A new transfer strategy to boost ultra-thin flexible temperature sensor performance

    In the fields of intelligent health care and robotic sensing, the development of ultra-thin flexible temperature sensors serves as a core prerequisite for achieving high conformability and integration. However, a fundamental bottleneck persists: the high-temperature processes required to ensure high sensitivity are incompatible with the low thermal tolerance of flexible substrates. Consequently, it remains challenging for ultra-thin devices to simultaneously achieve high sensitivity, excellent flexibility, and long-term stability.

    How pointing fingers shape what we see in old master paintings

    One of the most common human gestures, the pointing finger, appears frequently in Old Master paintings as a guiding cue. However, its influence on viewers' gaze has never been systematically investigated. Researchers in experimental art history at the University of Vienna used eye‐tracking methods to analyze whether and how viewers' eyes follow pointing gestures in works by renowned artists such as Raphael, Giorgione, Caravaggio, and Rembrandt.

    Pahon Cave provides a look into 5,000 years of surprisingly stable Stone Age tool use

    The Pahon Cave in Gabon offers archaeologists a well-preserved look into the Late Stone Age time period in central Africa, thanks to the stratified layers of guano-based sediment. This is in contrast with much of the surrounding areas, which are rich in acidic soils that make preservation difficult.
