Growing actual human skin cells directly over a mechanical joint

 Researchers at the University of Tokyo have successfully developed a groundbreaking biohybrid method to grow living human skin cells directly over a working mechanical joint. Led by biohybrid engineer Professor Shoji Takeuchi at the university's Biohybrid Systems Laboratory, the project marks a massive shift away from conventional synthetic robot materials like silicone or plastic, opting instead to build an actual biological layer over mechanical parts. [1, 2, 3]

How the Living Skin Was Cultivated

Instead of stitching a prefabricated sheet of tissue onto the machine, the team used a specialized tissue-molding approach: [1, 2]

• The Dermis Layer: The researchers immersed a three-jointed robotic finger into a tailored mixture consisting of collagen and human dermal fibroblasts. This solution naturally contracted to tightly conform and bond to the complex 3D shape of the robotic finger, producing a supportive inner layer. [1, 2, 3]
• The Epidermis Layer: Next, human keratinocyte cells were applied over the dermis. These cells multiplied and developed into a resilient, water-repellent outer epidermal layer. [1, 2]

Realistic Movement and Wrinkles

Because the skin grew perfectly around the robotic structure, it became flexible enough to seamlessly withstand the mechanical stress of continuous articulation. As the finger bent, the biological tissue stretched naturally, forming realistic knuckle wrinkles and creases around the joints rather than peeling or tearing away. [1, 2, 3, 4]

Assisted Self-Healing Properties

One of the most remarkable aspects of this biohybrid skin is its capacity to repair damage. During testing, researchers deliberately sliced the tissue with a surgical knife and placed a thin collagen sheet over the wound to act as a bandage. Within approximately seven days, the living fibroblast cells migrated into the patch, integrated the material with the surrounding tissue, and fully repaired the wound, restoring its original adhesive strength. [1, 2, 3, 4]

Current Limitations and Next Steps

While a massive step toward science fiction, the technology faces key hurdles: [1, 2]

• Constant Moisture Required: Because the mechanical finger lacks a natural circulatory system to deliver nutrients and hydration, the tissue currently needs to stay submerged in a nutrient-rich fluid to survive.
• Structural Durability: The engineered skin remains far more fragile than natural human skin. [1, 2]

The team’s ongoing research aims to incorporate microscopic blood vessels, sensory nerves, sweat glands, and hair follicles to keep the skin alive in open air and eventually grant robots the ability to feel temperature and touch. [1]

Russian drones with wire cutters?

 The phrase "Russian drones with wire cutters" points to two distinct, major technical developments in the ongoing conflict in Ukraine: drones built to physically cut steel infrastructure, and the drones that trail wires, which soldiers are trying to stop with literal scissors.

1. The 'Steel-Cutter' Drone Warhead

In late September 2026, Ukrainian officials reported that Russia deployed a new, specialized weapon for the first time. A jet-powered drone equipped with a steel-cutting shaped-charge warhead struck a high-voltage power pylon. [1, 2, 3]

• The Design: The weapon features a 40-kilogram main charge paired with four additional cutting modules. It is engineered for precision mechanical cutting rather than pure explosive destruction. [1]
• The Target: Instead of hitting power plants directly, this drone physically slices through critical civilian infrastructure like transmission lines, high-voltage pylons, and steel bridges. [1, 2]
• The Strategy: By physically cutting the "spine" of the electrical grid right before winter, the weapon is designed to cause widespread blackouts and complicate repairs, even without a massive explosive payload. [1]

2. Fiber-Optic 'Wire' Drones and the Countermeasures

The second connection involves fiber-optic guided drones and the physical "cutters" used to stop them. Russia pioneered the widespread use of these unjammable First-Person View (FPV) attack drones, which unspool microscopic polymer cables up to tens of kilometers long as they fly. Because they do not use radio frequencies, electronic warfare jamming does not work against them. [1, 2, 3]

This has resulted in bizarre, low-tech battlefield dynamics:

• Manual Snipping: On online forums like Reddit, users have widely discussed videos showing soldiers waiting in dense brush or wooded areas for a wire-guided drone to fly past so they can chase it and cut its trailing control wire with heavy-duty scissors or batons. Cutting the cable instantly severs the pilot's feed, causing the drone to crash. [1, 2, 3, 4]
• The "Chaharnyk" Razor Fence: To counter these unjammable threats more systematically, the Ukrainian tech firm Logika developed a defense system called the Chaharnyk. It functions as a dynamic razor fence or barrier designed to snag the trailing fiber-optic cables on specialized hooks and pull them through a mechanical cutter, slicing the wire 95% of the time. [1, 2]

The sheer volume of these wire-guided missions has left miles of discarded, tough polymer fiber draped across the landscape like giant spiderwebs, disrupting local wildlife and posing long-term issues for farmland. [1, 2]

İyad el-Baghdadi -- a Thread

 Eight years ago today, this journalist was murdered and dismembered inside the Saudi consulate in Istanbul by this incompetent idiotic despot.

Today, Saudi Arabia faces one the most serious crises in its modern history. These two stories should be read together.

---> A thread...

Human rights are important, but this is about more than human rights. It's about how systems fail. When disagreeing with the ruler becomes dangerous, idiotic ideas don't get filtered out. The idiot in power can waste trillions of dollars - and years the country cannot get back.

Take Vision 2030. Strip away all the PR and pomp and spectacle, and its core was an economic promise: Saudi Arabia can, within a few years, become no longer reliant on oil. It can become a post-oil regional power. It's 8 years later. Look where we are now.

Instead he wasted billions on idiotic giga-projects that eventually had to face reality. The Line. The Mukaab. Even his LIV Golf venture just filed for bankruptcy. What does Saudi Arabia get to show for it? It's still dependent on oil, and its oil routes are being squeezed.

And then there's Yemen. MBS entered the regional stage as defense minister in 2015, and waging war on Yemen was his personal project to establish his reputation as "the prince of decisiveness". And now the Houthis are stronger than ever are in control of Bab Al Mandab.

The idiot's entire project was to sideline all other voices in Saudi Arabia (and the region) because only he can fix everything. Jamal wasn't perfect. Nobody is perfect. But countries need to have enough independent voices who can look at the ruler and say: "This isn't working".

The idiot wanted to own Saudi Arabia's transformation. He wanted all the authority, all the decision, all the applause, all the credit. Well, now he owns all the consequences. What a fucking disaster.

Saudi Arabia is full of brilliant people. It did not, and does not, lack people capable of imagining a future. What it lacks is a system willing to let them have a chance, without having to kiss the idiot's fat ass or call the bloodthirsty idiot a genius.

It didn't have to end this way. Rest in peace, Jamal.

*** Sikh ***

 A Sikh is an adherent of Sikhism (preferred endonym Sikhi), a monotheistic religion founded over 500 years ago in the Punjab region of South Asia by Guru Nanak. The word Sikh translates to "disciple" or "learner" in Punjabi, originating from the Sanskrit root śiṣya. [1, 2, 3, 4]

Core Beliefs and Principles

Sikh teachings focus on a direct, personal connection with the divine and practical, ethical living in the everyday world. [1, 2]

• One Supreme Creator: Sikhs believe in one formless, genderless, and eternal God (Waheguru or Akal Purakh) who is present in all creation. [1, 2, 3]
• Equality of Humankind: The faith categorically rejects the caste system, ritualism, and discrimination based on race, class, or gender. [1, 2, 3]
• The Three Pillars: Sikhs are guided by three fundamental duties:
  1. Naam Japna: Keeping God in memory and meditating on the Divine Name.
  2. Kirat Karo: Earning an honest, ethical living.
  3. Vand Chhako: Sharing the fruits of one's labor and giving to those in need (charity). [1, 2, 3, 4]

Lineage of Gurus and Holy Scripture

The spiritual path of Sikhism was shaped by a succession of ten human Gurus from 1469 to 1708, whose collective spiritual essence is viewed as a single light passing from one leader to the next. [1, 2]

• Guru Granth Sahib: Before the passing of the tenth master, Guru Gobind Singh, the eternal spiritual authority was vested in the sacred scripture, the Guru Granth Sahib. Adherents treat this compilation of hymns and poetry as their living, perpetual Guru. [1, 2, 3]

Identity and Practices

Sikh identity is deeply tied to community service, spiritual discipline, and distinct visual markers. [1, 2]

• The Five Ks: Initiated members of the Khalsa (the community of initiated Sikhs founded in 1699) wear five articles of faith: Kesh (uncut hair), Kara (steel bracelet), Kangha (wooden comb), Kirpan (small ceremonial sword for defense), and Kachchera (cotton undergarment). [1, 2]
• The Turban: Most visibly, many Sikh men and women wrap their uncut hair (kesh) in a turban (dastaar), which signifies sovereignty, honor, equality, and commitment to community values. [1, 2]
• Langar: Every gurdwara (Sikh house of worship) maintains a communal kitchen called a langar, serving free vegetarian meals to all visitors regardless of background to practice radical equality. [1, 2]
