Skip your daily nap, shrink your brain.
A study by researchers from University College London and the University of the Republic in Uruguay has found that people who habitually take daytime naps tend to have significantly larger total brain volume—a key indicator of brain health that typically declines with age and is associated with reduced dementia risk.
The team used Mendelian randomization, a method that leverages genetic variants (present from birth) that make people more likely to nap regularly. By analyzing brain MRI scans and health records from more than 35,000 participants in the UK Biobank, they discovered that those genetically inclined to nap had brain volumes corresponding to 2.6 to 6.5 fewer years of aging.
While this doesn’t definitively prove that napping itself enlarges the brain, the genetic approach helps rule out many lifestyle-related confounding factors, providing stronger evidence of a potential causal relationship than traditional observational studies.
Notably, the researchers found no link between napping predisposition and performance on tests of reaction time, memory, or visual processing. However, previous studies have shown that short naps can deliver immediate cognitive benefits.
The study lacked specific data on nap duration, but prior research suggests naps of 30 minutes or less provide the greatest advantages while minimizing disruption to nighttime sleep.
This is the largest study to date linking regular napping with brain structure. Although further research is needed in more diverse populations, the findings bolster the idea that a brief daytime rest may help preserve brain volume and support long-term cognitive health.
Everyone's excited about Karpathy's autoresearch that automates the experiment loop.
We automated the whole damn thing.
Meet AutoResearchClaw: one message in, full conference paper out. Real experiments. Real citations. Real code. No human in the loop.
One message in → full paper out. Here's what happens in between:
Raids arXiv & Semantic Scholar, digests 50+ papers in minutes
Three AI agents FIGHT over the best hypothesis (one swings big, one sanity-checks, one tries to kill every idea)
Writes experiment code from scratch, adapts to your hardware
Code crashes at 3am? It reads the stack trace, rewrites the fix, keeps going
Results weak? It pivots to entirely new hypotheses and starts over
Drafts a full paper with citations, every single one verified against live databases
No babysitting. No Slack messages. No "hey can you re-run this."
Karpathy built the experiment loop. We built the whole lab.

Role & Objective:
Act as an Elite UI/UX Front-End Engineer specializing in Apple-tier micro-interactions and advanced CSS. Your task is to program a perfectly centered navigation bar in a strictly SINGLE HTML file containing all HTML, vanilla CSS, and vanilla JavaScript. No external libraries or frameworks (No Tailwind, React, etc.).
Design Concept - "True Liquid Glass":
CRITICAL INSTRUCTION: Do NOT generate standard, flat "glassmorphism" or basic frosted glass. I require a physically accurate "Liquid Glass" aesthetic. It must look like wet, poured clear resin, combining the high-gloss specular highlights of classic macOS Aqua with the volumetric spatial depth of modern Apple VisionOS.
1. The Liquid Glass Material & Lighting (CSS):
- Deep Refraction: Use `backdrop-filter` with extreme blur (e.g., 50px) and over-saturation (200%).
- Specular Highlight: Create a curved, semi-transparent white gradient on the top half using a pseudo-element (`::before`) to simulate a hard light reflection on a wet, rounded 3D surface.
- Caustics & Volume: Use multi-layered inner and outer `box-shadow` properties to simulate light refracting at the bottom edge and casting a realistic ambient drop shadow.
- Interactive Glare: Implement a soft radial-gradient spotlight inside the glass that dynamically tracks the user's mouse cursor (X/Y coordinates) using JavaScript and CSS variables (`mix-blend-mode: overlay`).
2. Navigation Layout & Elements:
- Center the pill-shaped navigation bar perfectly in the middle of the viewport.
- Include 3 main navigation items with minimalist, inline SVG stroke icons and text labels: "Home", "Call", and "List".
- Add a subtle vertical divider line after the main buttons.
- Next to the divider, add a Dark/Light Mode toggle button containing inline SVG Sun and Moon icons.
3. Animations & "Apple Magic":
- Sliding Active Pill: Create a solid background "pill" that sits *behind* the active navigation item's text/icon. When a different item is clicked, this pill must dynamically recalculate its width and slide to the new position.
- Spring Physics: The sliding transition MUST use an exact Apple-style bouncy spring easing curve (e.g., `transition: all 0.5s cubic-bezier(0.34, 1.2, 0.64, 1)`).
- Tactile Feedback: Buttons and icons must physically press down slightly (`transform: scale(0.92)`) when clicked (`:active`).
- Theme Switch: The Sun and Moon icons must smoothly rotate, scale, and cross-fade during the transition.
4. Background Environment (Crucial):
- Glass needs light and color to refract! Create a full-viewport, smoothly animated mesh gradient background using 3 large, heavily blurred, floating color blobs.
- Implement full Dark/Light mode logic using CSS variables (`:root` and `[data-theme="dark"]`). Toggling the theme must seamlessly transition the background blob colors, glass opacity, shadow intensity, and text colors.
Output ONLY the pristine, production-ready code. Prioritize maximum visual fidelity and silky-smooth 60fps animations.

So I asked Claude Code to build a recorder for me. I’ve never written Swift, so I blindly accepted

Google çıt çıkarmıyor, yine döşüyor bombaları
Bu defa yeni bir "sosyal medyamsı" geliyor... Yamsı? Çünkü google+ gibi değil. Onun yarası derin. Youtube gibi olur (akış ve etkileşim var. profil ve kişiler arası yok)
Muhtemelen de şöyle duyulur:
- MERHABA ARKADAŞLAR WEB KANALIMA HOŞ GELMİŞSİNİZ!
Derken? Yoksa... Gerçekten... AI'nin devirdiği WEB saltanatı geri mi dönüyor? Hemde büyük bir intikamla? Tüyler diken. Diken harbiden
Reuters ve Oxford babalar, bu raporu el ele hazırlamışlar. 2026 trend raporu. Discover senaryosu biraz alçaklardan hesaplanmış gerçi
Ama bence Google bunu yapmak zorunda
Ve yapacaktır. Çünkü tonlarca emare görüyorum. Onları da paylaşırım. Şimdilik sadece Discover yayıncısı olur muydum? Diye bir düşünün istedim...
