Fire officials say a methyl methacrylate-filled pressurized tank at GKN Aerospace in Garden Grove remained at 92°F overnight. Crews temporarily removed a ground hose used to cool the tank to gauge how it would respond without that measure, while water from a facility system continues cooling the vessel. Officials aim to lower the temperature as evacuation zones are scaled back and services resume in the affected area.
A Nature Geoscience study shows rising CO2 makes the stratosphere more efficient at radiating infrared heat into space, causing cooling of the upper atmosphere (about 2°C since the mid-1980s), with faster cooling higher up near the stratopause. Researchers describe a 'Goldilocks zone' of infrared wavelengths that drive this cooling, while ozone and water vapor play smaller roles. If CO2 doubles, stratospheric temperatures near the stratopause may drop roughly 8°C, highlighting a key, quantifiable climate fingerprint and its implications for Earth's energy balance and exoplanet atmospheres.
New Columbia University–led research, published in Nature Geoscience, identifies why Earth’s upper atmosphere has cooled while the surface warms: increasing CO2 alters how infrared light is absorbed and emitted in the stratosphere, with a particular “Goldilocks zone” of wavelengths driving efficient cooling that expands as CO2 rises. Ozone and water vapor play smaller roles. Cooling strengthens with altitude, and about a doubling of CO2 cools the stratopause by ~8°C, contributing to less heat escaping to space and a feedback that traps more heat near the surface. The study provides a quantitative mechanism for stratospheric cooling and has implications for understanding atmospheres beyond Earth.
Sony unveils the Reon Pocket Pro Plus, a refined wearable personal air conditioner that sits around the neck and cools via a chilled metal plate pressed to the skin. The upgrade adds a 2°C cooler plate surface, an improved cooling algorithm yielding about 20% more cooling, a redesigned exhaust vent for adjustable airflow, and a smaller Reon Pocket Tag 2 sensor for more accurate temperature and humidity readings. It will launch in Europe and other markets for €229/£199 (about $270), with no announced US release.
Sony has upgraded its wearable neck cooler, the Reon Pocket Pro Plus, delivering a 2°C (about 3.6°F) stronger cooling (20% boost) with a refined cooling algorithm and new stabilizing fins. It still runs on USB-C, offers up to 10 hours on a medium setting, and includes a second-gen Pocket Tag sensor and a companion app, while remaining usable without a smartphone. The Pro Plus will launch in the UK and Europe through Sony's store and retailers like Amazon, priced at £199 in the UK and €220 elsewhere; US availability is not announced.
Dyson has released its first handheld fan, the HushJet Mini Cool at $99. Weighing 7.5 oz and 1.5 inches in diameter, it offers five speeds plus a Boost mode, up to six hours of runtime on the lowest setting and about a three-hour charge. The brushless DC motor spins up to 65,000 RPM for up to 80 ft/s (55 mph) of airflow and operates around 52 dBA on speed 1 (72.5 dBA in Boost). It ships with a charging stand, USB-C, a travel pouch, and a lanyard, with additional colorways rolling out later. Dyson frames it as portable cooling and contrasts it with Shark’s ChillPill, which is pricier ($149.99), heavier, and offers different features like longer battery life, 10 speeds, and interchangeable heads.
A Reddit post describes placing two 1 mm thermal pads between the Neo’s processor heat spreader and the aluminum bottom case to act as a direct heatsink, reportedly letting the A18 Pro sustain higher clock speeds (around 3.3 GHz vs ~2.3 GHz under load) by transferring heat to the chassis and raising bottom temperatures. The mod requires removing the bottom cover and tapping power from the system’s heat management, and it could void warranty if Apple determines damage from the modification. While it can extend performance for cooling-limited tasks, thermal throttling remains a normal safeguard, and the modification mirrors past DIY cooling tweaks on Intel Macs and the M2 MacBook Air, with potential hot spots and regulatory surface-temperature considerations.
A PBKreviews teardown reveals the Galaxy S26 Ultra uses a four-layer cooling stack (vapor chamber, graphite pad, thermal pads, and thermal paste)—an upgrade over the S25 Ultra’s first three components. The added thermal paste improves heat transfer, and despite a thinner chassis, the phone maintains a 9/10 repairability score; pre-order perks are also highlighted as the window closes soon.
A UC Riverside study (not yet peer-reviewed, posted on arXiv) projects peak water demand for U.S. data centers could reach 697 million to 1.45 billion gallons per day by 2030—roughly matching New York City's daily water supply—driven by water-intensive cooling. Building this capacity could cost $10–$58 billion, with much of the financial burden on host communities; the researchers urge requiring peak-demand reporting and forging corporate–community partnerships to fund upgrades, since most operators disclose only annual usage. If water is scarce, data centers may switch to less efficient dry cooling, increasing energy use and stressing grids. The study uses a conservative peak-to-average ratio of 4.5.
Sony has released a new model of the PlayStation 5 Pro, the CFI-7100B01, which addresses overheating, noise, and power consumption issues of the previous version without sacrificing performance, indicating ongoing improvements and hints at future console developments.
Apple is planning to introduce vapor chamber cooling technology to the iPad Pro, similar to what was implemented in the iPhone 17, to better manage heat generated by high-performance tasks, with an expected release around spring 2027.
Microsoft has developed a microfluidic cooling method that could significantly improve heat removal from microchips, potentially enabling more powerful chips and more energy-efficient data centers, though real-world effectiveness remains to be seen.
Research suggests that electric fans may not effectively cool the body during high heat conditions and could potentially be harmful, especially for vulnerable populations. Fans are more effective at night when outdoor temperatures drop below indoor temperatures, and using water or wet skin with a fan can enhance cooling. The key to staying safe during heat waves is understanding when and how fans can be beneficial, and employing additional cooling strategies.
The article humorously highlights the playful and adorable ways German Shepherd siblings stay cool during summer, from splashing in a tiny pool to enjoying swimming pools, cooling mats, and frozen treats, all while showcasing their mischievous and entertaining personalities.
Fans can help improve sleep by providing a cooling breeze and white noise, but their effectiveness varies depending on factors like temperature, fan type, and individual health conditions.
