Just read LeCun's latest paper. His team trained the first world model that can't collapse.

Let me explain why this matters.

It's called LeWorldModel.

World models predict what happens next physically. Objects moving, falling, colliding.

That's the base layer for robots that plan, cars that simulate before they steer, any AI that acts in reality instead of just talking about it.

The catch is nobody could train these reliably.

The models kept cheating. They'd map every input to the same output. Like a weather app stuck on "sunny" forever. Technically predicting. Completely useless.

So teams piled on fixes. Frozen encoders, stop-gradient hacks, 6+ loss hyperparameters. A fragile stack too brittle for production.

This team asked a different question. What if you make collapse mathematically impossible?

An encoder turns each video frame into a small vector. A predictor takes that vector plus an action and guesses the next one.

First loss: how wrong was the guess.

Second loss: a regularizer called SIGReg that checks if vectors spread out like a bell curve. If they start looking the same, the loss spikes.

The model can't cheat because the math won't let it.

That simplicity is what makes the results possible.

Six hyperparameters became one. 15M parameters. Trains on one GPU in hours. Plans 48x faster. Encodes with ~200x fewer tokens.

Open-source. I could run this on my own hardware.

Which changes who gets to build physical AI. Not just big labs anymore. Any team, any startup, any grad student.

LeCun has pushed JEPA as the path forward. The criticism was always training instability. This paper removes that objection.

Two directions compete in AI right now. Bigger LLMs with more compute. Or small models learning physics from raw pixels.

This is how IRC-compliant speed humps should be laid, allowing vehicles to cross safely at around 25 km/h without discomfort. These humps have been laid by PWD following IRC standards.

In contrast, the unscientific humps, including the rubber hump opposite the Police Commissioner's Office, are causing unnecessary slowdowns, traffic congestion, and pose a risk to two-wheelers.

Request @hd_brts to redesign these humps as per IRC standards.

@girishgn28 @NHAI_Official @SpDavanagere @NHAIROBengaluru , please clarify.

[Girish G N @girishgn28]

Stops are being done at Chalageri toll. Kindly place the speed limit sign at visible locations then take fine. Open collection is going on this place. @DrPrabhaSSM & @SpDavanagere Kindly intervene otherwise it’s very frustrating to either pay fine or settlement dey openly offer.

[Girish G N @girishgn28]

Yesterday many ppl faced same issue in Haveri- Davanagere Stretch. Esp. Near Chalageri. Why pay hefty toll on NH48 for speedlimit is 80Kms. Generally highway speed limit set by @NHAI_Official is 100kms.
Dey are stopping vehicle if it cross just 80km. @SpDavanagere kindly look it.

[Varun Rao @varungrao]

@ravikeerthi22 Now this impractical speed limit has been set on NH48 near Haveri which is a six lane highway. I don't know why NHAI is not raising an objection against the speed limit set by police on NH limits.

One major run-time bottleneck in multi-GPU training happens during GPU synchronization.

For instance, in multi-GPU training via data parallelism:

- The same model is distributed to different GPUs.
- Each GPU processes a different subset of the whole dataset.

India’s fight against TB is achieving remarkable momentum.

The latest WHO Global tuberculosis report 2025 highlights that India has recorded a commendable reduction in TB incidence since 2015 and it is nearly twice the global rate of decline. This is one of the sharpest drops seen anywhere in the world. Equally heartening is the expansion of treatment coverage, the fall in ‘missing cases’ and the sustained rise in treatment success. I compliment all those who have worked towards achieving this success. We remain committed to ensuring a healthy and fit India!

There is a point about R&D I make repeatedly: R&D is not expensive but time intensive and best results are achieved by teams who stay committed long term.

American companies solved the need for long term committed people with the H1-B visa and the extremely long green card process, both of which made it painful or risky to switch jobs. This gave them a source of committed talent.

Since companies tend to promote those who are committed, Indians got promoted. There was no conspiracy to promote Indians, it was one consequence of the visa/green card system.

Tech companies in India need to realize the importance of this. It is about creating that culture of long term focus on R&D.

[Sridhar Vembu @svembu]

I have heard so many accounts from Sindhi friends about how their families had to leave everything and come to India during partition. They rebuilt their lives and Sindhis have done well in India.

I am sad to say this, but for Indians on an H1-B visa in America, this may be that time. Come back home. It may take 5 years to rebuild your lives but it will make you stronger.

Do not live in fear. Make the bold move. You will do well. 🙏

Bengaluru @OfficialBMRCL speed should be at least 50 kilometres per hour, not 35 kilometres. Once the airport line is open, speed should be 100 kilometres per hour, not the proposed 50 kilometres. Speed is the most essential part of Metro. It can’t run like a BMTC bus. @ChristinMP_

[Ministry of Education @EduMinOfIndia]

IIIT Dharwad is integrating education, research, and entrepreneurship to shape India’s innovation ecosystem. Through the @dharwad_iiit Research Park (IDRP) and its Incubation Centre for Entrepreneurship (ICE), the institute supports deep-tech startups with advanced facilities, expert mentorship, seed funding, and patent assistance.

Flagship programs such as the Yuva Udhyami Startup Challenge combine structured mentorship, financial aid, and strong industry linkages to build a culture of innovation among students and faculty. The institute also fosters global collaborations, including the Global Wales Partnership Funding 2025 and Cardiff Metropolitan University (UK), while hosting distinguished Professors of Practice from Technion-Israel Institute of Technology and Swinburne University of Technology (Australia).

Complementing these efforts are initiatives like the Capacity Building, Design, and Entrepreneurship (CBDE) program and the New Age Innovation Network (NAIN), which strengthen capacity building and entrepreneurship across sectors.

I have written a letter to Hon’ble Chief Minister Shri @siddaramaiah regarding the recent withdrawal of land acquisition for the aerospace project.

The Karnataka government has withdrawn the acquisition of 1,777 acres in Devanahalli’s Channarayapatna region, initially planned for an aerospace project, due to farmers' strong protests

While farmers' concerns are valid, Karnataka plays a vital role in India’s aerospace and defense sectors — contributing nearly 65% of national output and ranking third globally. A project of such significance should not be shelved but rather relocated to a more suitable region.

North Karnataka, Specially Hubballi, Dharwad, Belagavi is ideal — with skilled human resources, adequate land, and supportive infrastructure. The region is economically lagging due to lack of major industrial investments. Relocating the aerospace project here will boost regional development and provide employment to thousands of youth.

I appeal to Hon’ble Chief Minister @Siddaramaiah and Industries Minister @MBPatil to consider this strategic move and act swiftly.
