The possible applications of olive pomace: A study reveals the most sustainable option‎

The extraction of olive pomace oil is cited as the most sustainable alternative for the recovery of the olive oil industry's byproducts, according to a methodology developed by the UCO that considers economic, environmental and social indicators. The olive oil industry is a good example of how to tackle the challenges of sustainability in the agri-food sector. Each olive campaign generates tons of alperujo, the main byproduct of the extraction of olive oil, a derivative that must be managed. For decades, mills have been on the circular economy path, establishing different ways of exploiting olive pomace that go beyond just avoiding pollution.

Q&A: What we've learned about how students are using AI, and how to help them‎

Much is being said about the wonders of artificial intelligence (AI) and how it is the new frontier. And while it provides amazing possibilities in fields like medicine, academics are debating its advantages for university students.

Mediterranean pine needle loss analyzed for more efficient forest management‎

Reforested areas in the Baza (Granada) and Los Filabres (Almería) mountain ranges have experienced severe die-offs in recent years, with extensive woodland loss. Needle or leaf loss (defoliation) is one of the best indicators of tree health, particularly in pine forests under stress. When trees lose their needles, or leaves, their photosynthetic capacity deteriorates significantly, reducing growth and often leading to mortality.

Cryogenic cooling material composed solely of abundant elements reaches 4K‎

In collaboration with the National Institute of Technology (KOSEN), Oshima College, the National Institute for Materials Science (NIMS) succeeded in developing a new regenerator material composed solely of abundant elements, such as copper, iron, and aluminum, that can achieve cryogenic temperatures (approx. 4K = −269°C or below) without using any rare-earth metals or liquid helium.

Why futuristic, tech-centered 'smart city' projects are destined to fail‎

For residents of European cities—with their snarled traffic, drafty old buildings, creaking public services and gray winters—it's easy to see the appeal of moving to a brand-new, high-tech metropolis.

Reading the moon's diary, one speck of dust at a time‎

Magnetism on the moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts to detect it in returned regolith samples blended together all of the rocks in those samples, leading to confusion about the source—whether they were caused by a strong inner dynamo in ages past, or by powerful asteroid impacts that magnetized the rocks they hit. A new study from Yibo Yang of Zhejiang University and Lin Xing of the Chinese Academy of Sciences, published recently in the journal Fundamental Research, shows that the right answer seems to be—a little of both.
