Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have now provided new insights into the process, emphasizing the critical role of both chaos and order.
Loss of lake ice has wide-ranging environmental and societal consequences
The world's freshwater lakes are freezing over for shorter periods of time due to climate change. This shift has major implications for human safety, as well as water quality, biodiversity, and global nutrient cycles.
It could take over 40 years for PFAS to leave groundwater
Per- and polyfluoroalkyl chemicals, known commonly as PFAS, could take over 40 years to flush out of contaminated groundwater.
Climate Change can Alter Methane Emission and Uptake in the Amazon
Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse gas in upland forests by 70%, with global impacts, according to a study conducted...
Increasing Plant Diversity in Agriculture can Promote Soil Carbon Sequestration
The study investigated whether increasing plant diversity through use of undersown species in field ecosystems can affect the structure and functioning of microbial communities to promote soil health and carbon sequestration.
What’s Causing the Recent Spike in Global Temperatures?
About 18 months ago, climate scientists began to notice something strange.
Researchers discover new insights into bacterial photosynthesis
Researchers have discovered new understanding of bacterial photosynthesis. Using cutting-edge techniques, investigators have unveiled intricate detailed images of the key photosynthetic protein complexes of purple bacteria. These images shed new light on how these microorganisms harness solar energy.
In studying the mating rituals of fruit flies, scientists may have learned something about how brains evolve
Researchers have identified how the architecture of brain circuits helps different species flexibly adapt to new mating signals across evolutionary timeframes.
Study Finds Mercury Pollution From Human Activities Is Declining
MIT researchers have some good environmental news: Mercury emissions from human activity have been declining over the past two decades, despite global emissions inventories that indicate otherwise.
Arctic Sea Ice Near Historic Low; Antarctic Ice Continues Decline
Arctic sea ice retreated to near-historic lows in the Northern Hemisphere this summer, likely melting to its minimum extent for the year on Sept.11, 2024, according to researchers at NASA and the National Snow and Ice Data Center (NSIDC).
