Self-organization of living matter into complex structures: How light pattern impacts aggregation of active filaments
When active filaments are exposed to localized illumination, they accumulate into stable structures along the boundaries of the illuminated area. Based on this fact, researchers at the Max Planck Institute for Dynamics and Self-Organization (MPI-DS).....»»
New research challenges dark matter theory in galaxy formation
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter.....»»
Uncovering health impacts of forever chemicals on freshwater turtles
A study in Science of the Total Environment has measured concentrations of PFAS—also known as forever chemicals—in Australian wildlife, following an analysis of freshwater turtle (Emydura macquarii macquarii) populations in Queensland......»»
Gender inequality ingrained in global climate negotiations, say researchers
Climate governance is dominated by men, yet the health impacts of the climate crisis often affect women, girls, and gender-diverse people disproportionately, argue researchers ahead of the upcoming 29th United Nations Climate Summit (COP29) in Azerba.....»»
What oxygen levels in the Tijuana River estuary tell us about the impacts of the sewage crisis
Researchers Jeff Crooks and Stephany Garcia checked the minnow traps left at the murky mouth of the Tijuana River on a sunny October morning......»»
Monitoring Webb"s mirrors for optimal optics
NASA's James Webb Space Telescope is the largest and most powerful telescope ever launched to space. Its mirror is composed of 18 individual segments that have been aligned so accurately, that they effectively work as a single giant (21.6-foot, or 6......»»
Hubble captures barred spiral galaxy NGC 1672
This NASA/ESA Hubble Space Telescope image features NGC 1672, a barred spiral galaxy located 49 million light-years from Earth in the constellation Dorado. This galaxy is a multi-talented light show, showing off an impressive array of different celes.....»»

How to build a home radio telescope to detect clouds of hydrogen in the Milky Way
If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or even an array of dish antennas such as the Very Large Array. What you likely don't imagine is something that resembles a TV dish in your neighbor's b.....»»
Report: Countries must dramatically increase climate adaptation efforts and bridge the finance gap
As climate impacts intensify and hit the world's most vulnerable hardest, the "Adaptation Gap Report 2024: Come hell and high water," from the United Nations Environment Program (UNEP), finds that nations must dramatically increase climate adaptation.....»»

NASA wants to bring back supersonic air travel with its X-59 jet......»»
Astronaut’s photo shows Earth as you’ve never seen it before
NASA's oldest serving astronaut has shared an image taken from the space station that shows Earth in a most unusual way......»»
Plastics pollution worsens the impacts of all planetary boundaries, new study says
Plastics are not as safe and inert as previously thought. A new research study written by an international team of researchers uses the planetary boundaries framework to structure the rapidly mounting evidence of the effects of plastics on the enviro.....»»
Record drought in Amazon impacts 420,000 children: UNICEF
More than 420,000 children in the Amazon basin are being badly affected by a drought parching much of South America that is impacting water supplies and river transport, UNICEF said Wednesday......»»
Nearly three years since launch, Webb is a hit among astronomers
