Can insulin-dependent diabetics stay in space? This will be one of the areas of research by astronauts who will fly to the International Space Station (ISS), probably this May, as part of the Axiom 4 mission. Indian Air Force pilot, Shubhanshu Shukla, will be among the four astronauts part of the space-flight – the first time an Indian will fly to the ISS.

The larger thrust of the experiment is to demonstrate that astronauts with insulin-dependent diabetes can be supported for short duration stays in microgravity. This can be done by demonstrating accurate blood glucose testing, data transmission, and insulin viability on the ISS. This research will also help enable people with diabetes to participate in future space missions, thus expanding the eligibility of crew and expanding access to space to more people. The project is being undertaken in partnership with Burjeel Holdings PLC, a United Arab Emirates-based healthcare services provider, said a statement from Axiom. The company organises commercial flights to the ISS and is also in the process of building the first private space station. The lead investigators on the study are John Marshall and Alex Rubin, affiliated to Axiom.

Beyond the “micro-gravity” environment in a space station, the insights gained could potentially improve healthcare delivery on earth, particularly in remote and extreme environments. The technology used in orbit could enable remote monitoring and treatment of oil rig workers with chronic conditions at sea, adventurers with chronic conditions in extreme environments, and even patients receiving care at home, Burjeel said in a statement.

Astronauts on the ISS spend a substantial amount of time conducting a slew of experiments and gathering data on how ordinary biological process are altered by micro-gravity. “Studying biological processes in microgravity offers unique opportunities to understand diseases in ways that are impossible to replicate on Earth. The absence of gravity alters cellular behaviour, enabling deeper insights into conditions such as Alzheimer’s, Parkinson’s, and cancer. Previous research in space has already contributed to significant insights in protein crystallization and cellular ageing,” it added.

Shamsheer Vayalil, Founder and Chairman of Burjeel Holdings, underscored the significance of this collaboration, stating, “Burjeel Holdings is proud to collaborate on this groundbreaking study aboard Ax-4, which marks a milestone in medical research and diabetes management. The findings from this study have the potential to not only benefit future astronauts but also translate into meaningful advancements in patient care here on the ground.”

The moment underscored something essential: seeing (and feeling) is believing. The iPhone 17 Air, by all early impressions, is not just another iteration. It’s something else, perhaps the first visually exciting iPhone since the X.

A Threat to the Pro Line?

Here’s the catch: the iPhone 17 Air likely won’t be Apple’s most expensive phone. That title will still belong to the Pro and Pro Max. But if the Air proves as seductive in hand as it appears in leaks, Apple risks cannibalising its own high-margin flagship line.

Why spend more on the Pro when the Air is thinner, sleeker, and just as capable for most users?

It’s a fair concern. But also, potentially, a calculated one.

Betting on Excitement Over Margins

The truth is, Apple needs a hit, not financially, but culturally. For years now, iPhone design has plateaued. The 15 Pro is a phenomenal device, but it doesn’t feel new. The last time Apple truly reset expectations was in 2017 with the iPhone X. The iPhone 17 Air won’t be quite as revolutionary. But it could deliver something Apple hasn’t achieved in years: buzz. The kind of buzz that fuels lines outside stores, envious stares across cafe tables, and the irresistible need to upgrade.

In short, the Air could reignite passion for the iPhone.

And if it means shaving a few billion off Pro model sales in the short term? Apple may be willing to take the hit—because the long-term gain is loyalty, excitement, and momentum heading into the next big thing (iPhone Fold, anyone?).

Will It Cannibalise Pro Sales?

The Pro line has long justified its price with features like ProMotion, triple lenses, and titanium builds. But if the Air looks and feels fresher, lighter, and more “2025,” casual buyers and even some power users could opt for form over function. The wild card will be pricing and performance. If Apple gives the Air a high-end chip and flagship-level display, all while keeping it competitively priced, the Pro models might feel redundant to all but the most hardcore enthusiasts.

They use the natural process of water evaporation to cool the air, making them an eco-friendly cooling option that doesn’t rely on harmful refrigerants. This process also adds moisture to the air, which is beneficial in dry regions where air conditioning can cause dryness and discomfort.

What makes Symphony coolers stand out?

Symphony coolers stand out for their innovative features, energy efficiency, and commitment to delivering clean and effective cooling. Their signature i-Pure technology includes a multi-stage filtration system that removes dust, allergens, bacteria, and odours, ensuring healthier air circulation. Equipped with high-performance honeycomb cooling pads and a Cool Flow Dispenser, these coolers offer enhanced water retention and even cooling across the room. Symphony models are also known for their low power consumption, making them a cost-effective and eco-friendly alternative to air conditioners.

Is a Symphony cooler suitable for humid climates?

Symphony coolers work best in dry climates where evaporation effectively cools the air. In humid regions, the cooling effect may be less noticeable, as moisture in the air reduces evaporation. However, Symphony offers models with advanced i-Pure technology that include humidity control and air purification, making them more efficient in mixed or slightly humid conditions. If you’re in a coastal area, consider using the cooler in well-ventilated rooms or during drier parts of the day for better performance. For high humidity, an air conditioner may be a more effective option.

Can a Symphony cooler be used with an inverter during power cuts?

Yes, many Symphony coolers are inverter-compatible, making them a reliable cooling solution during power cuts. Their low power consumption means they can run on most home inverters without draining the battery quickly. However, it’s important to check the cooler’s wattage and your inverter’s capacity before use. Opt for models labelled as inverter-compatible for maximum efficiency. Using a Symphony cooler with an inverter ensures uninterrupted comfort, especially during peak summer hours when electricity issues are more frequent. It’s a great feature for areas with frequent load-shedding or unreliable power supply.

Factors to consider before buying coolers for home

1. Room Size: The size of your room determines the type of cooler you need. Personal coolers are ideal for small rooms, while desert coolers are better for larger areas. Always check the air delivery rate (measured in CFM or m³/hr) to match your room size.
2. Climate Conditions: Coolers work best in dry climates where evaporation is more effective. If you live in a humid area, choose a model with humidity control or consider whether an air conditioner might be a better option.
3. Cooling Pads: Look for coolers with honeycomb or cellulose pads—they offer better cooling and last longer than traditional aspen pads. Honeycomb pads also require less maintenance and are more efficient in water retention.
4. Water Tank Capacity: A larger tank means longer cooling hours without refills. Choose a tank size that suits your daily usage and avoid constant water top-ups, especially during peak summer.
5. Portability and Design: Check if the cooler has caster wheels and a compact design for easy movement and space-saving. A sleek, modern cooler can also blend well with your home décor.
6. Additional Features: Look for user-friendly features like remote control, inverter compatibility, water level indicators, auto shut-off, and multi-stage air purification (like Symphony’s i-Pure tech) for enhanced comfort and convenience.
