Turning emissions into fuel

MIT researchers have developed a new membrane-based system that can convert carbon dioxide into useful fuels for cars, trucks, and planes, as well as into chemical feedstocks. The process uses heat energy from solar or waste sources to store chemical energy in form of useful products.

UK obesity levels among the worst in Europe -- heart disease statistics from more than 45 countries

The study reveals huge inequalities persist with heart disease accounting for over 50% of all deaths in many middle income countries, compared to less than 30% in high income countries. The UK has the highest prevalence of adult obesity in males and 2nd highest in females, and ranks joint 5th for raised blood cholesterol.

How bat brain tracks prey

Neural recordings of wild bats reveal a layered structure in the superior colliculus facilitating rapid tracking and capturing of prey through echolocation. The study contributes to understanding of SC function during naturalistic behaviors, finding both sensory and motor neurons throughout the midbrain region.

Barley no longer an afterthought in beer flavor

Researchers at Oregon State University found notable differences in the taste of beers malted from two barley varieties, revealing novel flavors that carry through malting and brewing into beer. The study's results have significant implications for the brewing industry, particularly for beer connoisseurs.

Autism and the smell of fear

Researchers at Weizmann Institute of Science found that individuals on the autism spectrum exhibit distinct reactions to 'smells of fear' and 'calm sweat', including changes in anxiety levels. This suggests a possible underlying connection between smell, social cues, and early brain development in autism.

In harm's way

Researchers at University of California - Santa Barbara found that about half of hydraulically fractured wells exist within 2 to 3 kilometers of domestic groundwater systems. The study analyzed data from nearly 27,000 wells in 14 states and suggests increased water monitoring efforts are needed to protect water quality.

Get'em while they're hot

Researchers found that providing real-time cues about sold items and current stock levels can be a viable strategy for offline merchants. Consumers tend to choose products with lower sales and fewer copies remaining in stock. However, when brand familiarity is factored in, the impact of stock level data diminishes.

Clean sweep for agriculture

Rothamsted Research emphasizes the importance of accelerating UK agriculture to meet post-Brexit challenges through a focus on sustainable growth. The institute advocates for a dynamic, innovative model that prioritizes co-development, sharing, and engagement to drive impact.

Physicist assumes the possibility of vestiges of an Universe previous to the Big Bang

Brazilian researcher Juliano Cesar Silva Neves challenges the standard cosmological model by proposing the elimination of the spacetime singularity and the possibility of a prior contraction phase. The current expansion may be preceded by contraction, with potential vestiges still present in the universe.

A series of fortunate events

Researchers traced ancient zircon minerals' chemical signatures to understand the recycling of carbon from the mantle to the surface. The study suggests a series of fortunate events led to optimal conditions for releasing anomalous amounts of carbon, which in turn shaped the modern carbon cycle.

The origin of a new species of Darwin's finches

Researchers from Princeton University and Uppsala University report the origin of a new lineage of Darwin's finches through hybridization between two distinct species. The study reveals that reproductive isolation was established in just two generations, with the new lineage becoming ecologically competitive and unique.

High-speed quantum encryption may help secure the future internet

Researchers have developed a high-speed quantum encryption system that can transmit encryption codes five to 10 times faster than existing methods, potentially securing the future of the internet. The system uses photons of light and advanced detectors to encode and decode keys, making it secure from common attacks even with imperfect ...

When magma prevents volcanic eruptions

Researchers from UNIGE and Roma Tre used thermal and experimental models to explain caldera resurgence, a process that prevents volcanic eruptions. The leftover magma behaves like a 'rubber sheet' due to its higher viscosity, stopping the new magma from reaching the surface.
