Hybrids increase fish biodiversity in lakes of East Africa
Hybrids increase fish biodiversity in lakes of East Africa
When two individuals from different species mate, the offspring is known as a hybrid. As a result of the genomes being mixed, sometimes phenotypes are produced that deal with new environmental conditions better than the two parent species. Very often, hybrids are not able to reproduce, but there are quite a number of exceptions to this, including the cichlids.

Tracking power plant emissions in real time
Tracking power plant emissions in real time
Stanford scientists have developed a precise way to measure U.S. power plant emissions 24/7. The new tool will enable grid operators and big electricity consumers to reduce their carbon footprint in real time. About 30 percent of U.S. greenhouse gas emissions come from power plants that generate electricity by burning fossil fuels.

Australia at its most stripped back
New research from The Australian National University (ANU) and Geoscience Australia could provide a much clearer picture of the Australian landscape, and how to better manage it under a changing climate. The study, published , shows the Australian continent at its 'barest' - or least vegetated. Dr Dale Roberts designed a new mathematical algorithm that accurately estimates the earth's reflected light at every location from satellite imagery.

Migratory birds shrinking as climate warms, new analysis of four-decade record shows
Migratory birds shrinking as climate warms, new analysis of four-decade record shows
ç €äoe“中文 हिन्दी Português Español Share on: Share on Twitter Share on Facebook Share on LinkedIn North American migratory birds have been getting smaller over the past four decades, and their wings have gotten a bit longer. Both changes appear to be responses to a warming climate. Those are the main findings from a new University of Michigan-led analysis of a dataset of some 70,000 North American migratory birds from 52 species that died when they collided with buildings in Chicago.

Calls to curb infant formula’s carbon footprint
Urgent action is needed to protect breastfeeding and reduce formula's carbon footprint - especially for "unnecessary" toddler milks, according to an expert at The Australian National University (ANU). Dr Julie Smith, who has studied the economics of infant feeding for over 20 years, has published a paper in the International Breastfeeding Journal on the global environmental damage of milk formula, particularly greenhouse gas emissions.

For some corals, meals can come with a side of microplastics
Under a black light, fluorescent green microplastics are seen in the water during a small demonstration experiment. In the 2018 experiment described in the paper, cauliflower coral (above) ingested microplastics when prey was also present in the water, but avoided eating microplastics when no prey was there.

Underground answers
As the world waxes warmer, scientists are scrambling to prioritize conservation efforts. A new global study of earthworm diversity suggests looking at soil, as climate change could seriously affect earthworms and the many functions they provide. Based on data compiled from 6,928 sites in 57 countries (including over 100 sites sampled by University of Minnesota researcher and study coauthor Adrian Wackett), the work reveals that climate variables-temperature and especially precipitation-influence earthworm distributions and diversity far more than the properties of the soils they inhabit.

Reveals climate change impact on Antarctic penguins | University of Oxford
Antarctic penguins have been on the forefront of climate change, experiencing massive changes to their natural habitat as the world's temperatures and human activity in the region have increased. Now, new research has revealed how penguins have dealt with more than a century of human impacts in Antarctica and why some species are winners or losers in this rapidly changing ecosystem.

New membrane technology to boost water purification and energy storage
Imperial College London scientists have created a new type of membrane that could improve water purification and battery energy storage efforts. The new approach to ion exchange membrane design, which is published today , uses low-cost plastic membranes with many tiny hydrophilic ('water-attracting') pores.

Genomic gymnastics help sorghum plant survive drought
A new study led by UC Berkeley researchers reveals how sorghum crops alter the expression of their genes to adapt to drought conditions. Understanding how sorghum survives harsh conditions could help researchers design crops that are more resilient to climate change. (UC Berkeley photo by Peggy Lemaux) Scorching temperatures and parched earth are no match for the sorghum plant - this cereal crop, native to Africa and Australia, will remain green and productive, even under conditions that would render other plants brown, brittle and barren.

Many pregnancies are shorter as climate change causes more 90-degree days
A UCLA study suggests that climate change is causing many women to have shorter pregnancies than they would normally, which could pose risks for infant health and child development. According to research published today , birth rates were 5% higher on days when the temperature exceeded 90 degrees Fahrenheit.

Improved health check for running waters
Improved health check for running waters
If one turns a stone over in a river or stream, it swarms with tiny animals: caddisflies, water beetles, freshwater shrimp, and snails. The invertebrates living on the beds of water bodies that can be seen with the naked eye, called macroinvertebrates, are rather unimposing, but for science and the protection of surface waters they are of great importance.

Global levels of biodiversity could be lower than we think, new study warns
Biodiversity across the globe could be in a worse state than previously thought as current biodiversity assessments fail to take into account the long-lasting impact of abrupt land changes, a new study has warned. The study by PhD graduate Dr Martin Jung , Senior Lecturer in Geography Dr Pedram Rowhani and Professor of Conservation Science Jörn Scharlemann , all at the University of Sussex, shows that fewer species and fewer individuals are observed at sites that have been disturbed by an abrupt land change in past decades.
