这次美国访华晚宴坐在马斯克和库克中间C位最亮眼的，是蓝思科技创始人周群飞，从农村打工妹到中国女首富，完全没有任何背景全靠自己白手起家。她出生在湖南的一个小村庄，5岁时母亲去世，父亲也因工伤残疾双目失明，家徒四壁，16岁交不起学费被迫辍学去广东打工，在一家工厂流水线打磨玻璃，白天干活，晚上疯狂自学，考了会计证、电脑操作证等技能证书，就这样过了几年，她拿着靠打工攒的2万块，拉上哥哥姐姐、嫂子姐夫等8个亲戚，在深圳开了一家小作坊，做手表玻璃加工，她一个人修机器、跑销售，就这样又干了4年。
到了2000年后手机行业开始大规模发展，一次偶然的机会她的手表玻璃厂接到了TCL手机屏幕的订单，她看到了手机玻璃市场的巨大潜力，于是迅速成立了蓝思科技，专门负责手机玻璃的生产研发和销售，一开始只做国产手机和山寨机，但是直到有一次想谈下摩托罗拉的订单，但外企的质量要求非常严格，她赌上几乎全部的资源配合摩托罗拉，拿下了全球销售超过1亿台的V3订单，直接把蓝思科技推到了行业领先位置，随后顺利拿下诺基亚、三星等外企。
关键的转折点又一次出现在了2007年，当时乔布斯发布初代iPhone，彻底把手机往全玻璃触屏的方向变革，乔布斯那变态的工艺要求全球都找不到符合的厂商，周群飞敏锐的意识到这又是一个巨大的机会，于是带领团队和苹果工程师联合攻关了3个月，突破关键工艺，成功量产了第一代iPhone玻璃面板，从此拿下苹果长期合同，后续的iPad、MacBook等几乎所有苹果设备全部都交给了蓝思科技，也帮助蓝思科技在触摸玻璃面板领域成为全区最大公司。
这也是为什么她能坐在库克旁边，那为什么马斯克也坐在她旁边呢？
蓝思科技在玻璃面板干到全球第一后，开始往更加多元的智能化设备发展，包括汽车座舱和机器人，其中汽车领域包括车窗、中控等已经拿下了特斯拉、宝马、奔驰、理想等30家车企，机器人领域则主要负责关节、传感器等部件，这些都和马斯克的业务有深度重合。
一个15岁辍学只有初中文凭的女生，从湖南农村出来白手起家成为中国女首富，40年后进入中美会谈，坐在了马斯克和库和中间，这就是周群飞的故事。

🚨 Scientists just built a refrigerator with NO compressor and NO refrigerant gas.

Just electricity.

Using a multilayer ceramic capacitor, researchers created a solid-state cooling system that changes temperature when an electric field is applied.

The result:
• ~3–4.5 K cooling swings
• works across room temperature
• survives >10 MILLION cycles
• no moving parts
• projected 70–90% Carnot efficiency

This is electrocaloric cooling and it may become one of the biggest threats to conventional refrigeration in decades.

Older materials only worked ABOVE room temperature and needed a brutal 42-day annealing process.

This new PST–PMW material:
• cools down to ~230 K
• avoids the expensive anneal
• handles massive electric fields
• maintains strong entropy transitions

The physics is beautiful.

An electric field reorganizes the material’s internal dipole structure, reshaping entropy inside the lattice and producing a real temperature drop.

Not “cold generation.”
Controlled entropy engineering.

If this scales:
• silent refrigerators
• ultra-efficient chip cooling
• vibration-free scientific systems
• wearable thermal control
• next-gen EV cooling

We may be watching refrigeration evolve from mechanical compression…
to programmable matter.

Follow me if you want the future of physics before it hits mainstream.

There was a time when stardom was a fortress. In the 90s, Ruby Bhatia wasn't just a VJ; she was the electric pulse of a new, liberalised India, reportedly commanding Rs 1 lakh per show. Rahul Roy wasn't just an actor; he was the face of a generation’s collective heartbreak, the Aashiqui boy whose silhouette defined romance and whose haircut was the bestseller in every saloon. Govinda? He was—and is—the undisputed king of the masses, a comic genius who could make a cinema hall shake with a single pelvic thrust.

Fast forward three decades, and the fortress has been dismantled by the relentless, voyeuristic machinery of social media. Today, these icons find themselves under the harsh, unforgiving glare of a "content-hungry" digital mob that mistakes struggle for failure and evolution for desperation.

Recent headlines have taken a perverse pleasure in dissecting Ruby Bhatia’s career shift. Yes, the woman who once defined "cool" is now a life coach charging Rs 3,000 for a six-month program. To the keyboard warriors, this is a "fall from grace." To any sane mind, it is a woman finding meaning after a nervous breakdown, choosing to make mental health accessible to the masses rather than gatekeeping it for the elite.

Similarly, Rahul Roy has been subjected to the "cringe" treatment for appearing in social media reels with unknown creators. The internet, in its infinite cruelty, ignores the fact that this man is a brain stroke survivor. He is fighting aphasia, paying off legal debts that predated his illness, and trying to "stay active" and work for as long as he is alive. When he asks his trolls to find him "decent work" instead of mocking his reels, he isn't showing desperation; he is showing a spine of steel that most "influencers" couldn't dream of possessing.

Then there is Govinda, the man who once gave the Khans a run for their money, now frequently seen performing at school annual days and weddings. The "dark shadow" of social media brands these "small shows," as if the size of the stage dictates the stature of the legend. Govinda’s response is a masterclass in humility: "I never let my ego influence my work." Whether it’s a Chief Minister’s event or a local school function, the man dances because he is a performer. There is more dignity in one of his "wedding steps" than in the entire collective output of a thousand anonymous trolls.

Social media has birthed a generation of spectators who believe that unless you are at the absolute zenith of your power, you should vanish into the shadows. We have become a culture that feeds on the "tragedy" of the legacy act.

But here is the truth: There is nothing sad about a veteran getting up and going to work. There is nothing "cringe" about an icon refusing to be defeated by a health crisis or a shifting industry. The desperation doesn't belong to Ruby, Rahul, or Govinda. The desperation belongs to the social media ecosystem that needs to tear down giants just to feel tall.

🚨BREAKING: Two researchers from UPenn and Boston University just published a paper that should be uncomfortable reading for every CEO automating their workforce right now.

The argument is straightforward. Every company replacing workers with AI is also eliminating its own future customers. Laid off workers stop spending. Enough of them stop spending and nobody can afford to buy anything. The companies that fired everyone end up selling into an economy with no purchasing power left.

Every executive can see this. The math is not complicated. But here is why nobody stops.

If you do not automate, your competitor does. They cut costs, lower prices, take your market share, and you collapse anyway. So every company automates knowing it is collectively destructive because the alternative is dying alone while everyone else survives. The researchers proved this is a Prisoner's Dilemma playing out in real time.

The numbers are already moving. Block cut nearly half its 10,000 employees this year. Jack Dorsey said AI made those roles unnecessary and that within the next year the majority of companies will reach the same conclusion. Salesforce replaced 4,000 customer support agents with AI. Goldman Sachs deployed a coding tool that lets one engineer do the work of five. Over 100,000 tech workers were laid off in 2025 and AI was cited as the primary driver in more than half those cases. 80% of US workers hold jobs with tasks susceptible to AI automation.

The researchers tested every proposed solution. Universal basic income does not change a single company's incentive to automate. Capital income taxes adjust profit levels but not the per-task decision to replace a human. Collective bargaining cannot hold because automating is always the dominant strategy.

They also identified what they call a Red Queen effect. Better AI does not solve the problem, it accelerates it. Every company chases faster automation to gain market share over rivals but at the end everyone has automated equally, the gains cancel out, and the only thing left is more destroyed demand.

The one thing the math says could work is a Pigouvian automation tax. A per-task charge that forces companies to account for the demand they destroy each time they replace a worker.

The conclusion is that this is not a transfer of wealth from workers to owners. Both sides lose. Workers lose income. Companies lose customers. It is a deadweight loss with no market mechanism to stop it on its own.

Scientists may have found a cure for type 1 diabetes.

For the first time ever, a man with type 1 diabetes is making his own insulin after receiving a cell transplant that required no immune-suppressing drugs.

Doctors took islet cells – the insulin-producing cells of the pancreas – from a donor. But before they were transplanted, scientists used CRISPR to edit three specific genes. Two of those edits made the cells less visible to the immune system. The third increased production of a protein called CD47, which acts like a biological shield, telling immune cells not to attack.

Then they injected the edited cells into the man’s forearm.

Within weeks, those cells began producing insulin. And 12 weeks later, they still are – with no rejection, no complications, and no immune-suppressing drugs. That’s a major breakthrough. In the past, cell transplants for type 1 diabetes almost always failed without heavy drugs to suppress the immune response. Those drugs come with serious risks: infections, organ damage, even cancer.

Another amazing Brazilian scientist, Dr. Mariangela Hungria, a microbiologist at Embrapa's soybean research center, spent decades studying bacteria that pull nitrogen from the air and feed it to plants.

The result: Brazil went from importing nitrogen fertilizer to becoming the world's largest soybean exporter — using microbes instead of chemicals.

Her work won the 2025 World Food Prize. But the real prize is the 40% reduction in synthetic fertilizer use across Brazilian agriculture.

This isn't just about soybeans. It's about a different model of agriculture: partner with biology instead of dominating it.

Two teenagers from Pennsylvania just solved a problem most engineers ignored. Rohan Kapoor and Jack Reichert created the "Go Green Filter" — a 3D-printed device that attaches to your car's exhaust pipe. It doesn't just reduce emissions. It converts CO2 into oxygen. Using microalgae. The same process plants use — photosynthesis. They built a bio-reactor with water, LED lights, and living algae inside. The algae eat the carbon dioxide from your exhaust... and release clean oxygen back into the air. In testing? It cut emissions by 74%. They didn't wait for funding. Didn't wait for permission.
They 3D-printed the prototype themselves. Now it's being deployed in Indonesia. The cost? Low enough to scale globally. If this works at mass scale, it could reduce billions of tons of carbon annually. Two high school kids just did what billion-dollar companies haven't.
