“Wildlife biologists are monitoring species such as pelicans and plovers in the immediate path of the oil,” said Laura Burkholder at the Cornell Lab of Ornithology. “But we need bird watchers across the country to help us find out if birds that pass through or winter in the Gulf region carry contamination with them, possibly creating an ‘oil shadow’ of declines in bird reproduction hundreds of miles from the coast.”
To help, Burkholder said that anyone with an interest in birds can learn how to find and monitor nests as part of the Cornell Lab’s NestWatch project (www.nestwatch.org). It involves visiting a nest for a few minutes, twice per week, and recording information such as how many eggs it contains, how many chicks hatch, and how many leave the nest.
“Many birds that nest in backyards all across North America, such as Red-winged Blackbirds and Tree Swallows, spend part of the year along the Gulf of Mexico, where they could be affected by the oil spill,” Bukholder said. “Toxins often have profound effects on reproduction, and it’s possible that toxins encountered in one environment can affect the birds in another environment, after they arrive on their breeding grounds.”
When participants across large regions contribute information, Burkholder said, scientists can assess changes in nesting success in relation to environmental factors such as habitat loss, climate change, and pollution.
Citizen-science participants have helped the Cornell Lab monitor the success rates of nesting birds for 45 years. Now, Burkholder said, it’s especially critical to capture data on nesting birds to reveal the health of birds before they encounter the oil spill – as well as in the years ahead, to detect possible long-term effects.
To help the effort, visit www.nestwatch.org. In addition to accepting observations from the general public, NestWatch is available as a data repository for wildlife agencies and scientific organizations to support their research on the impacts of the oil spill.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
