There is no cure for Alzheimer’s disease and other forms of dementia, but the research community is one step closer to finding treatment.

University of Washington bioengineers have designed a peptide structure that can stop the harmful changes of the body’s normal proteins into a state that’s linked to widespread diseases such as Alzheimer’s, Parkinson’s, heart disease, Type 2 diabetes and Lou Gehrig’s disease. The synthetic molecule blocks these proteins as they shift from their normal state into an abnormally folded form by targeting a toxic intermediate phase. (more…)

Increased Temperatures Spell Trouble for Corals

ST. PETERSBURG, Fla.— Late-summer water temperatures near the Florida Keys were warmer by nearly 2 degrees Fahrenheit in the last several decades compared to a century earlier, according to a new study by the U.S. Geological Survey. (more…)

Breite Unterstützung: Zahl der Mitglieder und Förderer weiter gestiegen

Der NABU konnte auch im vergangenen Jahr wieder auf breite Unterstützung in der Bevölkerung bauen: 540.000 Mitglieder und Förderer engagierten sich 2013 für den mitgliederstärksten deutschen Umweltverband (Vorjahr: 520.000). Den größten Teil der Einnahmen von insgesamt 32,2 Millionen Euro (Vorjahr: 29,5 Millionen Euro) machten mit 16,5 Millionen Euro die Mitgliedsbeiträge aus (2012: 15,8 Millionen Euro). Die Spendengelder erhöhten sich gegenüber dem Vorjahr leicht auf 4,5 Millionen Euro (2013: 4,3 Millionen Euro). Der Anteil der Verwaltungskosten lag bei 3,6 Prozent der Gesamtaufwendungen. Konstant blieb die ehrenamtliche Naturschutzarbeit vor Ort: 35.000 NABU-Aktive sind bundesweit in 2.000 Gruppen organisiert. (more…)

Das bewegte Leben des Schreiadlers „KN“

Überleben dank grenzübergreifendem Artenschutz

Geboren wurde „KN“ – sein Name resultiert aus dem Kennring an seinem Fuß – 2009 in einem Horst in Lettland als das jüngere von zwei Geschwistern. Bei Schreiadlern, in Deutschland die am stärksten bedrohte Adlerart, kommt das einem Todesurteil gleich, da fast stets nur das ältere Junge aufgezogen wird. Dies ist ein Phänomen bei einigen Adlerarten, aber zum Beispiel auch bei manchen Kranicharten, wie bei dem extrem seltenen Schreikranich in Nordamerika. (more…)

Berkeley Lab Researchers Create Nanoparticle Thin Films That Self-Assemble in One Minute

The days of self-assembling nanoparticles taking hours to form a film over a microscopic-sized wafer are over. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.

Ting Xu, a polymer scientist with Berkeley Lab’s Materials Sciences Division, led a study in which supramolecules based on block copolymers were combined with gold nanoparticles to create nanocomposites that under solvent annealing quickly self-assembled into hierarchically-structured thin films spanning an area of several square centimeters. The technique is compatible with current nanomanufacturing processes and has the potential to generate new families of optical coatings for applications in a wide number of areas including solar energy, nanoelectronics and computer memory storage. This technique could even open new avenues to the fabrication of metamaterials, artificial nanoconstructs that possess remarkable optical properties. (more…)

ChemikerInnen erforschen Verderb von Lebensmitteln

Annette Rompel und ihr Team vom Institut für Biophysikalische Chemie der Universität Wien erforschen die “Bräunungsreaktion” beim Verderb von Champignons. Die ForscherInnen konnten nachweisen, dass das dafür zuständige Enzym bereits gebildet wird, wenn der Pilz noch gar nicht verdorben ist. Die Studie erscheint aktuell online in den renommierten Fachjournalen Phytochemistry und Acta Crystallographica. (more…)

Since joining the University of Chicago faculty in 2010, Hillary Chute quickly established herself as the campus’ resident comics expert. In addition to co-teaching a course on comics and autobiography with famed cartoonist Alison Bechdel, Chute organized a conference through the Richard and Mary L. Gray Center for Arts and Inquiry, which brought together the world’s leading cartoonists for three days of public conversation. The events of that conference are documented in a special issue of the journal Critical Inquiry, which Chute co-edited with colleague Patrick Jagoda, assistant professor in English Language and Literature and the College.

New research from UCL shows we will soon uncover the origin of the ultraviolet light that bathes the cosmos, helping scientists understand how galaxies were built.

The study published in The Astrophysical Journal Letters by UCL cosmologists Dr Andrew Pontzen and Dr Hiranya Peiris (both UCL Physics & Astronomy), together with collaborators at Princeton and Barcelona Universities, shows how forthcoming astronomical surveys will reveal what lit up the cosmos.
