UPenn researchers copied elephant skin in porous cement tiles; a mockup home stayed near 32°C versus 42°C and 52°C with commercial stucco surfaces
Researchers developed innovative cement tiles inspired by elephant skin for passive cooling. These tiles feature engineered cracks that absorb and slowly evaporate water to reduce heat. This technology offers a sustainable alternative to energy-intensive air conditioning systems. The material can be sprayed onto surfaces, providing a potential infrastructure solution for urban areas. Further development is needed to address durability, water usage, and cost concerns.
These large-, mid- and small-cap stocks can give more than 20% return in 1 year, according to analysts
Even if the ongoing conflict in the Gulf settles anytime soon (and we certainly hope it does), don’t be surprised if the Nifty and Sensex remain volatile for quite some time. In fact, the chances are that the volatility quotient of the market will remain high for several months after. That does not, however, mean that you should not think of buying stocks. You can, but be aware of the big picture.
In a divided America, the left and right unite to oppose artificial intelligence data centers

In 2023, Kitepower flew a 176-pound fabric wing over a Mayo bog for the first time. 3 years later, it has logged more than 90 flights and over 100 hours generating airborne wind-energy data
Kitepower is testing an unconventional approach to renewable energy at a designated airborne wind-energy site in County Mayo, Ireland. Instead of using a traditional tower and rotating blades, the system sends a lightweight fabric wing into the sky while a tether connects it to ground-based generation equipment. The wing flies repeated figure-eight patterns, creating pulling force that turns a generator as the tether unwinds.
Ambani's Rs 2.7 lakh cr underground bet can save India from shocks
Reliance Industries has proposed a Rs 2.73 lakh crore, 30-year investment to develop an underground coal gasification complex in Andhra Pradesh. The project could convert deep coal into syngas for hydrogen, methanol, ammonia and synthetic natural gas, helping India reduce dependence on imported LNG and chemical feedstocks. However, commercial viability, geological risks and UCG technology at scale remain major challenges.

In 2024, scientists tested a zigzag-shaped wall prototype; it was up to 3.1°C cooler than a conventional radiative-cooling wall in outdoor tests
Engineers have created a groundbreaking zigzag wall that cools itself through a unique design. This structure lowers its temperature by directing heat away into the sky while also reflecting thermal energy emanating from hot ground surfaces. By utilizing this passive cooling technology, there's potential to significantly decrease the energy consumption associated with air conditioning. However, more advancements are needed before this innovation can see broad implementation.
In 2023, scientists built a rooftop tile that opens its cooling vents when hot and closes them when cold, using no electricity and cutting cooling costs 3.1-fold
Innovative engineers have created high-tech roof tiles that adjust themselves to optimize building temperatures automatically. By utilizing wax actuators, these tiles can switch between reflecting and absorbing sunlight efficiently. This breakthrough drastically lowers energy costs for heating and cooling, unlike older passive designs that needed significant temperature differences to work well. This technology presents a vital advancement in alleviating the energy demands on power grids.
A fridge in the wrong part of your home may quietly consume more electricity; researchers explain why
Refrigerator placement significantly impacts household electricity bills. Room temperature around the appliance is the primary driver of energy use. Warm environments force the compressor to work harder and consume more power. Studies confirm ambient temperature is the largest single factor. Simple placement adjustments can reduce unnecessary energy consumption.
Building for scale, security and privacy: Inside PhonePe’s AI playbook
As AI capabilities become more deeply embedded across products and platforms, the interface itself becomes less visible. What matters is whether people can express what they want to do, in their own language, in their own way, and get the result they are looking for.
ET Prime Special Series: Multibagger or IBC - Part 71: This small-cap auto supplier is trying to become a consumer brand again
The most interesting part of this old auto story is not nostalgia. It is how the company, after leaving the consumer vehicle market, has rebuilt itself as an auto-component business that today serves domestic and overseas customers. That base is now being used to support a fresh EV push. But the transition has made the investment case complex. Not every capability within the wider EV ecosystem is owned by the listed company in the same way, while FY25 earnings were helped by non-operating income. The comeback to the B2C business has begun, but its economics are still being tested.

Time to take a little risk with a 1- to 2-year perspective? 5 mid-cap stocks from different sectors with upside potential up to 20%
When the big picture is a coin-toss, why waste time on predictions? What is the big picture? Well, nobody knows. Anyone who says with confidence where crude, or the tariff talks, or the monsoon, or earnings may land over the next few months (or quarters, for earnings) is just guessing. We are not saying that they are lying, but guessing. It is the guessing part that needs to be avoided at this point of time.
