An international study investigating why wild tomatoes are more resistant to the tomato leafminer (Phthorimaea absoluta) than cultivated varieties revealed that the secret lies in the spatial structure of a plant defense molecule. The researchers mapped the biochemical origin of this difference and demonstrated that altering four amino acids in a single enzyme is sufficient to alter the structure of the substance and increase its toxicity against the pest. This finding paves the way for […]

Hula hooping may be literal child's play, but as it turns out, the physics behind the gym-class staple is so complicated that scientists have spent decades trying to understand how the hula hoop defies gravity.

In nonreciprocal active matter, agents act differently on each other, seemingly in violation of Newton's third law. This principle can result in various active matter traits, such as self-propulsion, molecular regulation and collective motion.

Since the production of graphene in 2004, two-dimensional materials have been sparking scientific and technological interest. As they are only a few atomic layers thick, or even just a single atomic layer, they can exhibit special electronic, magnetic or chemical properties—which make them particularly interesting for applications such as electronics, catalysis and energy storage.

An international study involving ICTA-UAB reveals that large energy corporations use corporate sustainability narratives to legitimize wind, solar and hydropower projects that, in practice, exclude communities from fair economic and financial returns and ignore the projects' social and environmental impacts.
