Nanoscale resistors for quantum devices

Researchers have created high-value, compact nanoscale resistors using thin-film chromium oxide, enabling faster development of quantum devices for computing and fundamental physics research. The new resistors can be tuned by controlling oxygen content, making them compatible with quantum phase-slip circuit requirements.

Controlling obesity with potato extract

Researchers found that potato extract reduced weight gain in mice fed an obesity-inducing diet by 9 grams. The extract's high polyphenol content is responsible for its benefits. This study suggests that potato extracts could be a low-cost solution for preventing both obesity and type 2 diabetes.

Put algae in your tank

Scientists have developed a unique combination of light and climate simulation to optimize algae cultivation, leading to higher yields and more efficient energy production. The system uses spectrum-tuned LEDs to simulate natural sunlight, allowing for precise control over the growth conditions of different algae species.

Penn researchers show commonalities in how different glassy materials fail

Penn researchers demonstrate that stiffness and strength scaling remain unchanged across various glassy materials, indicating a constant critical strain before catastrophic failure. This finding provides insight into the fundamental mechanism driving failure in glasses, suggesting cooperative motion of particles or atoms.

Doctors trained in higher expenditure regions spend more, may add to rising health care costs

A study by researchers at Milken Institute School of Public Health found that physicians trained in high-spending areas tend to practice more expensive medicine, even after completing residency. This can lead to higher healthcare costs for patients and contribute to the rising healthcare expenditure in the US.

Researchers assessing new treatment for common hospital-acquired infection, C. difficile

A team of researchers, led by Wayne State University's Steven M. Firestine, has been awarded a $3.2 million NIH grant to assess the effectiveness of a new treatment for C. difficile infection. The study aims to prevent the spore germination of the bacterium, which is responsible for the majority of hospital-acquired cases.

Fueling the future

A team of researchers at Argonne National Laboratory has developed an integrated modeling approach to understand the fluid dynamics of fuel injectors in modern engines. The study aims to improve engine design and simulation, reducing trial and error and increasing efficiency.

The gold standard

Computational modeling allows researchers to design efficient and affordable catalysts from gold, reducing the need for large amounts of expensive precious metals. The method has potential impact on energy-and-environment related fields, such as automotive exhaust and hydrogen production.

Simeprevir-based therapy offers cost-effective alternative in treatment of hepatitis C

A new study has shown that a simeprevir-based therapy is as effective as the standard of care in treating chronic Hepatitis C virus infection, with fewer adverse events. The study found that simeprevir was well-tolerated and could be a viable alternative for patients who cannot access or afford newer treatment options.

Distraction, if consistent, does not hinder learning

A new study published in Psychological Science found that consistent distraction during learning does not hinder learning, but rather helps recall motor skills. The researchers discovered that dividing attention between tasks during learning can create an internal representation that boosts recall when a similar cue is present.

The legend of the kamikaze typhoons

Historical records describe the intense Kamikaze typhoons that struck Japan in 1274 and 1281, preventing a Mongol conquest. A new sedimentary reconstruction reveals these storms were more frequent during this time period, supporting their significant role in shaping Japan's geopolitics.
