Northern lakes act as CO2 chimneys in a warming world

A new study reveals that many lakes worldwide release large amounts of CO2 into the atmosphere, with northern hemisphere lakes expected to increase emissions due to climate change. The study found that most lake CO2 originates from surrounding land, highlighting the impact of land use changes on greenhouse gas emissions.

The great northern cod comeback

Researchers tracking northern Atlantic cod stock off Newfoundland and Labrador report significant recovery over the past decade, with tens of thousands to several hundred thousand tonnes of fish. The study credits favourable environmental conditions, including an increase in capelin as a key food source, and severe reduction of fishing.

Chance effect of lab's fluorescent lights leads to discovery

Scientists at Penn State and University of Chicago discovered a new way to use light to draw and erase quantum-mechanical circuits on topological insulators, allowing for non-invasive and faster experimentation. The technique uses ultraviolet and bright red light to manipulate the electronic properties of these materials.

Ants on the march in non-native conifer forests

A species of ant, the northern hairy wood ant (Formica lugubris), is thriving in newly formed coniferous forests in the North York Moors National Park. The ant's population has expanded into these plantations, suggesting they provide a suitable habitat for this forest specialist species.

Ancient genomes link early farmers to Basques

A team of researchers has discovered that early Iberian farmers are the closest ancestors to modern-day Basques, contradicting previous hypotheses. The study also reveals that farming was brought to Iberia by groups migrating to northern and central Europe, leading to admixture with local hunter-gatherer populations.

Arabs or Jews, children who need pain relief in the ER get it

A study published in Annals of Emergency Medicine found that children with broken bones or joint dislocations in northern Israel received equal pain relief, regardless of their ethnicity. The study, which lasted four years, including an 11-week period of armed conflict, showed that opioid therapy was administered to nearly all children...

Switching off street lights at night does not increase car crashes and crime

A new study published in the Journal of Epidemiology and Community Health found that reducing street lighting at night does not lead to an increase in road traffic collisions or crime. Local authorities can safely reduce energy costs and carbon emissions by carefully assessing risks, according to the researchers.

Access to electricity is linked to reduced sleep

Research comparing traditional hunter-gatherer communities with and without access to electricity reveals that those with electricity sleep an average of one hour less per night than those without. The study suggests that artificial light disrupts humans' natural circadian clock and sleep-wake cycle, leading to shorter nights.

Switch off the lights for bats

Researchers found that bat activity was lower in street-lit areas than dark locations with similar habitat. Only Leisler's bat showed a positive association with street lighting, highlighting the need to reconsider urban planning strategies.

Giving LEDs a cozy, warm glow

Scientists develop a thermoresponsive coating that changes the color of white LEDs when dimmed, creating a warmer glow. This innovative technology uses liquid crystal and polymeric materials to create a temperature-dependent shift in light emission.

Drinking age laws have a significant effect on collisions among young drivers

A study by University of Northern British Columbia researchers found that drivers just older than the legal drinking age had a significant increase in motor vehicle crashes compared to those immediately under the restriction. Raising the drinking age to 19 years could prevent up to 583 police-reported collisions per year.
