Mechanics of the infinitely small: NanoGear, towards a molecular gear

Gears and mechanical transmissions are at home in the Emilia-Romagna region, the Motor Valley of northern Italy. A team of researchers from the University of Bologna and the Institute for Organic Synthesis and Photoreactivity ...

Part of the Greenland ice sheet may be close to a tipping point

Data from the Jakobshavn drainage basin of the Central-Western Greenland ice sheet reveals that the distinct mark of this part of the ice sheet has reached a tipping point. That is the conclusion by Niklas Boers from Potsdam ...

New tools needed to prevent plant disease pandemics

Plant diseases don't stop at a nation's borders and miles of oceans don't prevent their spread, either. That's why plant disease surveillance, improved plant disease detection systems and predictive plant disease modeling—integrated ...

New technology makes tumor eliminate itself

A new technology developed by UZH researchers enables the body to produce therapeutic agents on demand at the exact location where they are needed. The innovation could reduce the side effects of cancer therapy and may hold ...

A path to aggressive breast cancer

Researchers at Baylor College of Medicine have followed the progression of breast cancer in an animal model and discovered a path that transforms a slow-growing type of cancer known as estrogen receptor (ER)+/HER2+ into a ...

Mammals in the time of dinosaurs held each other back

A new study led by researchers from the Oxford University Museum of Natural History, University of Oxford and the University of Birmingham for Current Biology has used new methods to analyze the variability of mammal fossils, ...

Supernova remnant G53.41+0.03 investigated in detail

Astronomers have conducted detailed X-ray observations of a recently discovered supernova remnant (SNR) known as G53.41+0.03. Results of the observational campaign provide important insights into the properties of this object. ...

Greenhouse gases are shrinking the stratosphere

An international team of climate scientists has found evidence showing that human-created greenhouse gases have led to a shrinking stratosphere. In their paper published in the journal Environmental Research Letters, the ...

Educational intervention enhances student learning

In a study of low-income, urban youth in the U.S., researchers at Columbia University Mailman School of Public Health found that students exposed to Photovoice, an educational intervention, experienced greater improvements ...

In slow motion against antibiotic resistance

There are currently only a few synthetic agents that bind to and block the widespread membrane transport proteins, ATP-binding cassette transporters (ABC). Scientists at Goethe University and the University of Tokyo identified ...

Slow research to understand fast change

In a world that's changing fast, the Long Term Ecological Research (LTER) Network can seem almost an anachronism. Yet the patience and persistence that have generated 40 years of careful, reliable science about the Earth's ...
