The Infant Warmer is a sleeping bag-like device that uses a phase-change material to keep ...

According to the medical journal The Lancet, approximately 20 million low birth-weight and premature babies are born around the world every year. Of those, about 4 million die within four weeks. Many of those deaths take place because the infants can’t maintain a high enough body temperature on their own, and succumb to hypothermia. Incubators are designed to address this problem, but many hospitals in developing nations can’t afford them, nor can they provide the uninterrupted power supply that the machines require. The San Francisco non-profit group Embrace, however, is developing what could be an effective and affordable alternative – the Infant Warmer.  Read More

By tagging cod fish with data logging thermometers, European scientists have attained a be...

With the advent of robust, miniaturized electronic devices, an increasingly common method of studying wild animals involves temporarily attaching data-logging sensors directly to them. Some readers might have seen point-of-view video footage obtained with National Geographic's "Crittercam," for instance, or heard about the study where the migratory routes of Arctic terns were determined by putting tiny light loggers on the birds. Now, a consortium of scientists from nine European research institutions have tagged cod fish with mini-thermometers, to find out how they will be able to cope with rising ocean temperatures.  Read More

The new Euroengel compressor refrigerated container allows standard vehicles to carry cold...

Eberspächer is best known for its OEM work with vehicle manufacturers in the field of exhausts and heaters, but the company's new Euroengel compressor refrigerated range directly targets end users. The portable lightweight refrigerated boxes can reportedly be temporarily fitted to almost any commercial vehicle, and are transferable between vehicles. A 12 or 24-volt socket (cigarette lighter) is sufficient for all boxes and when stationary, they can be plugged into any mains electricity supply system in the world, from 110 to 240 volts. The cost-effectiveness in comparison to a refrigerated vehicle conversion is impressive, as purchased or leased vehicles can be retrofitted to become refrigerated vehicles, then sold or returned in original condition.  Read More

The iGrill is a cooking thermometer that transmits the temperature of cooking meat to its ...

It can be a tricky business, determining when grilled meat is properly cooked inside. You could buy a probe-equipped thermometer, but that would still need to be checked periodically – if you’re entertaining guests out by your barbecue, checking a thermometer is something that you could easily forget to do. What someone needs to invent is a cooking thermometer that notifies your iPhone, iPod or iPad via Bluetooth, when your steaks have reached the desired internal temperature. Needless to say, such a product has, in fact, been invented – it’s made by iDevices, and is called the iGrill.  Read More

Wind farms can cause change in local temperatures (Photo: Gizmag)

The benefits of wind farms in terms of global climate change are well recognized but according to researchers at the University of Illinois they can also affect local climates as well. The researchers observed that the area immediately surrounding a wind farm is slightly warmer at night and slightly cooler during the day compared to the rest of the region. The discovery could allow for strategies to mitigate those effects in areas where they are undesirable, or take advantage of them in others.  Read More

Lunar Microwave Radiometer Daytime Brightness Temperature map of the Moon

The first complete microwave image of the Moon taken by Chinese lunar satellite Chang'E-1 has been revealed. Chang’E-1 is China’s first scientific mission to explore planetary bodies beyond Earth and the on-board Lunar Microwave Radiometer has made it possible for the first time to globally map the Moon in microwave frequencies. Radar observations of the Moon are unable to provide thermal information, and microwave observations taken from Earth cannot reach the far side of the moon. So Chang'E-1's (CE-1) orbit was conducted at an altitude of 200km (124 miles) and allowed it to observe every location of the moon with a nadir view and at high spatial resolution.  Read More

New technology using silicon carbide electronics could enable radio transmitters that can withstand temperatures of up to 900 degrees Celsius (1,652 F). No, it’s not being developed so listeners can enjoy their favorite breakfast DJ in a worst-case global warming scenario. Rather the team behind the research envisions devices that could be dropped into the depths of the earth to provide early warning of a volcanic eruption or to provide real time data from the inside of a jet engine or nuclear power plant.  Read More

Raizan and team used optical tweezers to suspend the bead and observe Brownian motion for ...

Einstein said it couldn't be done. But more than one hundred years later physicists at the University of Texas at Austin have finally found a way to witness “Brownian motion”; the instantaneous velocity of tiny particles as they vibrate. The “equipartition theorem” states that a particle's kinetic energy, that due to motion, is determined only by its temperature and not its size or mass, and in 1907 Einstein proposed a test to observe the velocity of Brownian motion but gave up, saying the experiment would never be possible – not so.  Read More

A land based OTEC facility at Keahole Point on the Kona coast of Hawaii

Ocean Thermal Energy Conversion (OTEC) involves placing a heat engine between warm water collected at the ocean’s surface and cold water pumped from the deep ocean. Like a ball rolling downhill, heat flows from the warm reservoir to the cool one. The greater the temperature difference, the stronger the flow of heat that can be used to do useful work such as spinning a turbine and generating electricity. Researchers say that the temperature differential is around one degree Celcius greater on the leeward side of Hawaiian islands it is better suited for future ocean-based OTEC energy plants.  Read More

Multiple layers of graphene are being advanced as a new solution to fight overheating in e...

Overheating in laptops and electronic gadgets isn't just an annoyance to the end user — it's a major technological hurdle that puts a hard limit to the speed and energy efficiency of electronics. In a paper recently published on the journal Nature Materials, a team of scientists from the University of California found that multiple layers of graphene show strong heat conducting properties that can be harnessed in removing dissipated heat from electronic devices.  Read More
