What is the ideal room size for a window air cooler?

The ideal room size for a window air cooler depends on the cooler’s capacity (measured in liters). Generally, a 50 to 60 litres cooler is best for rooms up to 300 sq. ft. A larger cooler (70L or more) is suitable for bigger spaces. Be sure to check the cooler’s air delivery capacity and the manufacturer’s recommended coverage area to ensure efficient cooling.

How do wood wool cooling pads in window air coolers work?

Woodwool cooling pads absorb water and allow air to pass through them. As the warm air from the room passes through the wet pads, it gets cooled due to the evaporation process. This natural cooling method is highly effective in dry climates, helping maintain a comfortable indoor environment. Woodwool pads also last longer and provide better cooling efficiency compared to other materials.

What type of motor should I look for in the best window air coolers?

When shopping for a window air cooler, look for one with a motor that has overload protection. This ensures the motor does not burn out during extended use or if the cooler operates in a high-temperature environment. Motors with higher wattage (around 190W) usually provide more powerful airflow, making them suitable for larger spaces. Always check for warranty coverage on the motor for added peace of mind.

How can inverter compatibility impact the performance of window air coolers?

Inverter compatibility in window air coolers allows the cooler to adjust its motor speed according to the cooling demand. This can lead to energy savings, as the motor doesn’t run at full speed constantly, thus reducing electricity consumption. It also helps maintain a more consistent temperature by offering better temperature regulation. Inverter-compatible coolers are ideal for homes with fluctuating power supply or those aiming to reduce energy costs.

Factors to consider while purchasing the best window air coolers in 2025 during Amazon Sale 2025:

• Room Size: Ensure the air cooler has the right capacity (liters) to efficiently cool your room. Larger spaces need more powerful coolers.
• Cooling Pads: Look for coolers with high-quality wood wool or honeycomb cooling pads. These provide better evaporation and long-lasting cooling.
• Air Delivery and Fan Speed: Choose a cooler with adjustable fan speeds and good air delivery (CFM) to ensure effective cooling.
• Energy Consumption: Check if the cooler is inverter compatible or energy-efficient to reduce your electricity bill.
• Motor Protection: Go for coolers with overload protection to safeguard the motor and increase its lifespan.
• Portability and Placement: Ensure the cooler fits your window size and offers easy installation and portability.
• Warranty: Opt for models with a solid warranty on the motor or other components to ensure long-term reliability.
• Noise Levels: If you’re sensitive to noise, check the decibel levels to ensure a quiet operation.
• Brand Reputation and Reviews: Check customer reviews and ratings to gauge performance and durability.
• Sale Deals: Look for discounts, cashback offers, and no-cost EMI options during the Amazon Summer Sale 2025 for added value.

The launch of India’s maiden human space flight — Gaganyaan — has been pushed to the first quarter of 2027, nearly five years later than the original schedule as it races to ace technologies for such complex projects.

The first uncrewed mission of the Gaganyaan project is expected to be launched later this year, which will be followed by two more similar missions in 2026, Indian Space Research Organisation (ISRO) Chairman V. Narayanan said at a press conference.

“The first crewed mission is targeted for the first quarter of 2027,” Mr. Narayanan said and added ISRO would send a half-humanoid robot — Vyommitra — as part of the uncrewed mission before sending astronauts to low-Earth orbit.

Prime Minister Narendra Modi announced the Gaganyaan project during his Independence Day address in 2018 and set a target of 2022 for achieving India’s maiden human space flight.

The project has run into several delays, partly due to the COVID-19 pandemic that affected the training of astronauts, and complexities of mastering the crucial technologies required for the mission.

The crewed mission was expected to take place in 2025 and later slotted for 2026. It has now been delayed to the first quarter of 2027.

Besides developing the human-rated launch vehicle for the Gaganyan mission, ISRO scientists have also built from scratch the Environment Control and Life Support System (ECLSS) for the mission, which will involve taking the astronauts to low-Earth orbit of 400km above the Earth for a few days and getting them back safely.

The ECLSS will help maintain cabin pressure, humidity, temperature, quality of air and personal hygiene management system in the spacecraft during the duration of the mission.

“It is a very complex process. For the first time we undertook this development. I want to say, 90 per cent of the work is completed and we are in the final phase of qualification,” Mr. Narayanan said.

EXPLAINED | What will Gaganyaan change for India?

If successful, India will become only the fourth country after Russia, the U.S. and China to independently launch humans into space.

Mr. Narayanan said space docking experiments comprising two satellites launched by a PSLV rocket in December were successful and ISRO was planning SPADEX-2.

A proposal on this will be presented to the government soon, he said.

He said judicious use of fuel during the ongoing SPADEX mission allowed ISRO to conduct more experiments in orbit that included circumnavigating one satellite around the other in March.

Scientists also demonstrated open and closed loop circumnavigation experiments that are considered as foundational technologies for in-orbit servicing of satellites for extension of mission life.

Mr. Narayanan said ISRO was hosting, along with the International Astronautical Federation, the Global Space Exploration Conference (GLEX 2025) from May 7-9, positioning India as a partner in space exploration.

In a revolutionary breakthrough in the treatment of snakebites, researchers have used the potential of antibodies in the blood of a man who self-inflicted more than 200 snake bites to create an antivenom with amazing potential. The breakthrough is one step closer towards the creation of a universal snake antivenom that can save thousands of lives every year.
Tim Friede‘s extraordinary path has resulted in a scientific discovery with the potential to transform the way the world fights snakebites. His work may eventually give rise to a universal antivenom that saves thousands of lives annually, meeting the pressing need for effective treatments in areas where snakebites are common. There is still more to be done, but the development of this universal antivenom is a turning point in the battle against one of the world’s most lethal threats.

Tim Friede faced more than 200 bites from deadly snakes to fight for a cure

Tim Friede, a former truck mechanic from the United States, is at the center of this remarkable medical discovery. For nearly two decades, Friede intentionally injected himself with venom from some of the world’s deadliest snakes, including black mambas, cobras, taipans, and kraits. His goal was to build up immunity, allowing him to safely handle venomous snakes in his personal life and YouTube endeavors. With time, his mission changed, though. What had started out as a private experiment became an obsessive quest to advance snakebite treatments worldwide.
In spite of the dangers, including a number of near-lethal experiences — among them, a coma brought on by two cobras biting him — Friede held on. “I did not want to die. I did not want to lose a finger. I did not want to miss work,” he remembered some of his earliest battles. His own battle soon became a larger cause: saving lives of people far from medical care that could save them from snakebites.

Science behind the antivenom

Today, antivenoms are produced by inoculating tiny amounts of venom into animals such as horses, which then develop antibodies to combat the toxins. The antibodies are then collected and employed to develop therapeutic products. But one major setback in antivenom production is the specificity of the therapy. Current therapies have to be for the exact species of snake that inflicted the venom, and even within a single species, there can be varying levels of potency in the venom.
To overcome this limitation, researchers have turned their attention to broadly neutralising antibodies, which act against shared elements of venom across species. Centivax biotechnology company CEO Dr. Jacob Glanville led the quest for these universal antibodies. After learning about Friede’s extensive self-experimentation, Dr. Glanville was quick to contact him, seeing the potential of Friede’s blood to hold the key to a universal antivenom.

Potential in Tim Friede’s blood

The partnership between Friede and scientists was to find antibodies that could give broad protection against a range of snake venom varieties. The particular interest was in elapids, a venomous snake group that includes such species as coral snakes, mambas, and cobras. These snakes mainly employ neurotoxins, which kill their victims by paralyzing them, commonly resulting in death through respiratory failure.
By examining Friede’s blood, researchers found two important broadly neutralising antibodies that were capable of binding to two distinct classes of neurotoxin. Through further improvement, the team included a third ingredient, creating a powerful antivenom cocktail. In initial animal tests, the cocktail offered full protection against venom from 13 out of 19 species targeted by the antivenom. The other six species displayed partial protection, which Dr. Glanville termed an “unparalleled” width of coverage.

New antibodies offer hope for broad venom protection

The research group is now working on purifying these antibodies and seeing if the addition of a fourth element would yield complete protection against the neurotoxin-based venom of elapids. Although this is a significant advancement in snakebite treatment, much more work needs to be done. Next, they will investigate the other forms of venom, including those from vipers, which target the blood using hemotoxins instead of neurotoxins.
Prof. Peter Kwong, a researcher at Columbia University, believes that a fully comprehensive solution could be realized within the next decade. “In the next 10 or 15 years, we’ll have something effective against each one of those toxin classes,” he said. Although the results are encouraging, experts such as Prof. Nick Casewell, director of the Centre for Snakebite Research and Interventions at the Liverpool School of Tropical Medicine, warn that more comprehensive testing will be needed before the new antivenom can be administered in humans. Nevertheless, the discovery gives a good indication that a universal snake antivenom is within sight.
For Friede, this progress is personally fulfilling. “I’m doing something good for humanity, and that was very important to me. I’m proud of it. It’s pretty cool,” he shared. His selfless dedication to saving lives around the world has turned his once-dangerous experiment into a potential game-changer in global healthcare.
