Why Can’t We Power the World With Biofuels Yet?

Biofuels, derived from living matter, present a sustainable alternative to fossil fuels but face challenges in efficiency and production. First- and second-generation biofuels, while addressing food crop concerns, are less suitable for aviation and heavy vehicles. Third-generation biofuels from algae show promise, yet high costs and resource demands hinder progress. More research is essential.

A damaging partnership: How does the climate crisis further enforce gender inequality?

Climate change disproportionately affects women, particularly in low and middle-income countries, exacerbating gender inequality. Women, who dominate subsistence farming and informal economies, face barriers in education, healthcare, and employment. Extreme climate events lead to higher female mortality rates, and inadequate representation in policymaking hinders gender-responsive climate strategies, perpetuating these issues.

Can plants see?

The theory by botanist Gottlieb Haberlandt proposed that plants might “see” similarly to animals. Recent studies on the Boquila Trifoliolata vine reveal its remarkable mimicry of host leaves, suggesting potential sensory capabilities. Experiments indicate that this plant can adapt its appearance even without genetic information, supporting the hypothesis of “plant ocelli.”

Seaweed Farms: A Tasty Solution to Climate Change?

Seaweed farms are emerging as a significant climate change solution, with Europe aiming to cultivate 8 million metric tons annually by 2030. These farms can absorb carbon dioxide and offer versatile applications like biofuel, packaging, and fertilizers. However, sustainability concerns and potential ecological impacts require further research to ensure their effectiveness and minimize risks.

Can Animals Feel Empathy? Observations of Rescue Behaviour

Rescue behavior, primarily observed in humans, is rare among animals, where individuals risk harm to help others in distress without immediate personal benefit. Documented examples include Seychelles warblers and wild boars. The potential link to empathy suggests evolutionary advantages for group survival, highlighting animals’ capabilities and adaptability in response to environmental pressures.
