Researchers at Kobe University developed a method to preserve iPS cells directly in their culture dishes using D-proline as a cryoprotectant. This allows for easy automation of the process, reducing costs and increasing efficiency in regenerative medicine and drug discovery research. The breakthrough enables the direct freezing, thawin...
LyoWave, a company commercializing microwave heating technologies developed at Purdue University, has received a $304k NSF SBIR grant to scale its tech for pharmaceutical and biologics manufacturing. The project aims to increase manufacturing throughput and reduce costs.
Researchers discovered that trapped pockets of liquid can form inside ice, leading to extreme pressure that breaks glass. To prevent this, ensure water freezes slowly by supercooling or use containers with water-repelling surfaces.
A new study from Ohio State University finds that freezing food can lead to less waste, with households that practice home freezing exhibiting lower levels of total food waste. The study also highlights the importance of proper food storage techniques and education on reducing food waste, particularly among consumers.
Researchers have developed a color-changing material that can detect when medications get too warm, with tunable melting points to track temperatures from -94 to +99 degrees Fahrenheit. This innovative system has the potential to reduce electronic waste and improve medical cold supply chains.
A team from TU Wien has developed a method to cool several particles simultaneously by adapting the spatial structure of a laser beam to particle motion. The technique uses far-field wavefront shaping to optimize cooling and can be achieved without knowing the exact location or movement of the particles.
Researchers in Japan have created a method to preserve mouse sperm by freeze-drying it on a plastic sheet, enabling easy transportation via postcard. The 'sperm book' stored at -30°C, can hold thousands of sperm samples, and the mailing method has shown promising results with high offspring rates.
Researchers developed an aerogel for therapeutic use using a kitchen freezer and plant cellulose, demonstrating its potential for controlled release of medication and wound dressing. The material's density can be as low as 2kg per cubic meter, making it lightweight yet durable.
Scientists at UC Santa Barbara found that fruit flies use a mechanosensory channel called TMEM63 to detect the gritty texture of their food. This discovery sheds light on how animals perceive food and may have implications for human taste perception.
Researchers replaced R134a with energy-efficient R600a and added MWCNT nanoparticles, reducing electricity use by a quarter. The new mix improved cooling capacity and reduced evaporation temperature, making home refrigeration more accessible for low-income households.
Researchers used plug-and-play temperature controllers to create controlled-environment chambers from standard chest freezers, enabling the detailed observation of developmental rates in response to different temperatures. The study found a clear temperature-dependent effect on budbreak and seed germination, allowing for expanded resea...
A novel refrigerator design using a loop thermosyphon has shown promising results in reducing energy consumption, with an estimated 30% saving. This sustainable energy technology could lead to a significant decrease in household energy costs and greenhouse gas emissions.
A severe cold snap hit the Eastern US, with temperatures plummeting to record lows. The NASA Terra satellite captured an image of snow-covered states that appeared like they were sitting in a freezer due to Arctic and Siberian air masses.
A new study found that bed bugs can survive freezing temperatures for a certain period, but prolonged exposure to cold can lead to their death. The researchers discovered that minimum exposure times of 80 hours at -16°C are required for 100% mortality.
Researchers at Penn State have developed a compact freezer case using sound waves to substitute chemical refrigerants, reducing greenhouse gas emissions. The Navy has funded the project and is exploring its potential for distributed cooling systems on carriers.
A team of researchers at Penn State has developed a compact chiller that uses sound waves to cool ice cream, achieving temperatures below freezing point with minimal energy consumption. The innovative system, powered by high-amplitude sound energy, has the potential to revolutionize the way we produce and consume refrigerated foods.
Research shows that lower dasher rates can produce ice cream with the same physical structure and sensory attributes as higher rates, reducing energy consumption and increasing efficiency. The balance of ingredients, including milk fat, emulsifiers, and air, is crucial in achieving desired quality and texture.
Researchers at the University of Illinois found that microwave-blanched asparagus retains its nutritional value, taste, and texture better than traditionally blanched asparagus. The process involves short exposure to high heat, typically two to five minutes, using a microwave oven.
