Northwestern University scientists have developed a groundbreaking lifestyle medicine program that uses three wearable sensors — a necklace, a wristband and a body camera — to capture real-world eating behavior in unprecedented detail and with respect for privacy.

In a world first, researchers at Nagoya University in Japan have successfully developed a resonant tunnel diode (RTD) that operates at room temperature made entirely from Group IV semiconductor materials. The development of an RTD that operates at room temperature means the device could be deployed at scale for next-generation wireless communication systems. The use of only non-toxic Group IV semiconductor materials also supports more sustainable manufacturing processes.

In a pioneering study that combines economic and social analysis with environmental insights, researchers are examining the determinants of carbon emissions in West Java, Indonesia. The study, titled "Assessing Economic and Social Determinants of Carbon Emissions Towards Sustainable Development in West Java, Indonesia," is led by Prof. Robert Kurniawan from the Department of Statistical Computing at Polytechnic Statistics STIS and the Department of Population and Environmental Education at the Faculty of Post-Graduate, State University of Jakarta, Indonesia. This research offers a detailed examination of how economic and social factors influence carbon emissions, providing valuable insights for sustainable development.

A new study published in Biochar presents a detailed bibliometric analysis showcasing the rapid growth and diverse applications of biochar as a sustainable environmental remediation tool. The research, which examined over 7,000 scientific publications from 2007 to 2023, underscores biochar’s potential in soil improvement, water purification, air quality control, and carbon sequestration.

With CO2 emissions continuing unabated, an increasing number of policymakers, scientists and environmentalists are considering geoengineering to avert a climate catastrophe. Such interventions could influence everything from rainfall to global food supplies, making the stakes enormous. In brief, manipulating other aspects of Earth’s climate system might reduce some effects of climate change. But the wondrous complexity of our planet complicates every one of these proposals.

Cybersecurity training programs as implemented today by most large companies do little to reduce the risk that employees will fall for phishing scams–the practice of sending malicious emails posing as legitimate to get victims to share personal information, such as their social security numbers. 

That’s the conclusion of a study evaluating the effectiveness of two different types of cybersecurity training during an eight-month, randomized controlled experiment. The experiment involved 10 different phishing email campaigns developed by the research team and sent to more than 19,500 employees at UC San Diego Health.
