Protected bike lanes increase Citi Bike ridership in New York City, but painted bike lanes and sharrows do not show a statistically significant causal effect on ridership after accounting for confounding factors, according to a new study from researchers at NYU's Tandon School of Engineering published this week in npj Sustainable Mobility and Transport.
New research from the University of Victoria (UVic) has found that some kelp forests around Vancouver Island were disappearing far earlier than scientists previously thought, highlighting that climate change has been altering ecosystems long before most people were aware anything was wrong.
Since NASA's Artemis II crew members safely splashed down in the Pacific Ocean on April 10 after their record-setting mission around the moon, science teams have been busy collecting more data and combing through observations collected on the test flight. Results from these science investigations will help support safe human exploration of deep space and provide a blueprint for how future missions will conduct science on the lunar surface as NASA builds a moon base and develops an enduring human presence there.
Teams working on NASA's INCUS (Investigation of Convective Updrafts) mission, the first space-based survey of the dynamics of tropical convective storms, have completed assembly and tested two of the mission's small satellites, or SmallSats. Testing continues on the third SmallSat and is scheduled for completion no earlier than September ahead of a 2027 launch.
Water pollution caused by pharmaceuticals, pesticides and other organic contaminants is an increasing global issue, especially in regions with limited wastewater treatment infrastructure. A new doctoral thesis from Umea University in Sweden offers an innovative and sustainable solution by demonstrating how agricultural waste can be converted into effective materials for water purification.
On a blazing hot day in South Africa, female southern pied babblers can't think straight. The medium-sized black-and-white birds are trying to get at tasty mealworms behind a see-through barrier. On cooler days, the birds can quickly figure out that all they have to do is go around the small wall of plastic. But when the mercury goes up, the birds just keep stubbornly pecking at the barrier.
Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet's environment during that time is limited. However, samples from the moon and its cratered surface hint at the period's rate of cosmic impacts.
Colors brighten our lives and help define countless items we use daily—from the vibrant clothes we wear to decorative paper and packaging materials. What adds different colors to these things? Dyes, which bind themselves to the structure of the material they are coloring. For example, methylene blue (MB) is a dye used to color paper, leather products, silk and wool, and is also employed as a diagnostic agent and in the rubber and cosmetic industries. But what happens after these dyes have served their purpose?
Similar to the way DNA damage can contribute to human diseases such as cancer, it can also disrupt growth, development and survival in plants. Every day, plants endure environmental stresses such as sunlight, radiation, drought and soil stress—all of which can damage their DNA. However, they cannot move away from danger. How do plants handle all that damage?
Over the last decade, podcasts have become big business, with more than a fifth of UK adults listening to podcasts each week. The format particularly resonates with men, who are more likely than women to identify as podcast fans. Men are also overrepresented as podcast hosts.
