Biologists find how plants reconstitute stem cells

A team of biologists at New York University found that plants can reconstitute their stem cells from mature cells by replaying embryonic development. This process involves the recruitment of specialized cells to create a new set of stem cells, highlighting the importance of tissue behavior over stem cell properties.

Electricity and economics

A new study analyzes data from 21 countries and finds a positive correlation between electricity consumption and life satisfaction in some nations, while others show the opposite relationship. The research suggests that narrowing production-consumption gaps can improve human development outcomes.

How birds turn red

Scientists have identified a cytochrome P450 enzyme that allows some bird species to convert yellow pigments into red colors, enhancing color vision and possibly signaling individual quality. The discovery fills a gap in understanding the genetics of red coloration in birds, with implications for future research on evolution and ecology.

Atmospheric aerosols can significantly cool down climate

A new study from the University of Eastern Finland shows that increasing atmospheric aerosol concentration can significantly slow down and even temporarily stop global warming. Aerosol particles in the stratosphere prove extremely efficient in cooling down the climate, while those in the troposphere impact climate through cloud formation.

Dynamic dazzle distorts speed

Researchers found that dynamic dazzle patterns can distort perceived speed, causing a targeting error of up to 2m for a Land Rover. The effect remains even with only a small patch of the pattern visible, providing potential applications for camouflage on vehicles with central doors.

Plants are 'biting' back

Researchers from Bonn University discovered calcium phosphate as a structural biomineral in rock nettle plants, providing them with a hardened defense mechanism against herbivores. The unique material, structurally similar to reinforced concrete, is used instead of silica or calcium carbonate in most plants.

What can help dropouts?

Researchers found that treatment can reduce negative life outcomes for dropouts, such as getting arrested and needing government assistance. The study also identified factors that increase the risk of dropping out, including rejection by classmates in elementary school and becoming a parent at a young age.

Oldest actinopterygian from China provides new evidence for origin of ray-finned fishes

A newly discovered Chinese fossil, Meemannia, is the oldest known actinopterygian, providing new evidence for the origin of ray-finned fishes. The study reveals that early bony fish had 'cosmine'-like tissues, previously thought to unite lobe-fins and ray-fins, and confirms Meemannia as an early-diverging ray-finned fish.

Executive powers in the nursery

A new University of Toronto study examines the effect of infant vocalizations on adult cognitive conflict processing and attention. The research found that infant cries reduce attention to tasks and trigger greater cognitive conflict than infant laughs.

ORNL demonstrates large-scale technique to produce quantum dots

Researchers at ORNL have demonstrated a scalable method to produce semiconducting nanoparticles using bacteria-fed sugar at temperatures below 150 degrees Fahrenheit. This approach reduces production costs by approximately 90 percent compared to conventional methods, making it attractive for applications in electronics, displays, solar...
