New analysis challenges results of previous research
Researchers from the Johns Hopkins Bloomberg School of Public Health, the Tyndall Centre for Climate Change Research at the University of East Anglia, the Earth Institute at Columbia University, and other institutions conclude that the increase in the incidence of malaria in East Africa parallels warming trends over the last several decades. The new findings challenge the results of a study, "Climate change and resurgence of malaria in the East African highlands," which was previously published in the journal Nature. The original study, conducted by researchers from the University of Oxford, found "no significant changes" in long-term climate. The new analysis is published in the December 12, 2002, edition of Nature.
"Weather data is particularly sparse in East Africa, and the climate database used was originally created to pool information for analysis over large geographic areas. There is potential, therefore, for reaching spurious conclusions when using such climate data to study diseases at the local level," said Jonathan Patz, MD, MPH, lead author of the new analysis and assistant professor of environmental health sciences at the Johns Hopkins Bloomberg School of Public Health. He further added that, "Malaria is one of the worlds most climate-sensitive diseases, and the African Highlands is an area of key importance for climate-malaria risk studies."

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
