Long-necked 'dragon' discovered in China

A new species of long-necked dinosaur, Qijianglong, has been discovered in China with a remarkably lightweight neck and surprisingly stiff joints. The findings suggest that long-necked dinosaurs diversified uniquely in Asia during Jurassic times.

To reassure electric car buyers, combine battery leasing with better charging: INFORMS study

A new INFORMS study suggests that combining battery leasing with improved charging technology can alleviate range and resale anxieties, increasing electric vehicle adoption. The study finds that these combined models yield higher benefits than traditional ownership models, particularly in terms of emission savings and consumer surplus.

Demystifying nanocrystal solar cells

Researchers at ETH Zurich developed a physical model explaining electron transport in nanocrystal solar cells, which could lead to improved efficiency. The model reveals that nanocrystal size can be controlled to optimize absorption of sunlight, enabling the creation of flexible and thin solar cells with higher performance.

When aid brings conflict, not relief

Research by University of Illinois economist Ben Crost found that aid to villages in the Philippines increased violence. The villages that qualified for aid saw a significant increase in violence, while those that didn't participate experienced less violence. This suggests that aid can inadvertently make communities vulnerable to attacks.

Joint international research project leads to a breakthrough in terahertz spectroscopy

A joint international research project has led to a breakthrough in terahertz spectroscopy, enabling the analysis of nanocrystals and molecules at extremely low concentrations. Researchers successfully increased technique sensitivity using nanoantennas, allowing for enhanced absorption and spectroscopic signature retrieval.

To prevent new environmental disasters, China needs national conservation horizon scanning

A new study suggests that China should conduct national conservation horizon scanning to identify potential environmental problems that have not yet been noticed by society. This could help prevent large-scale environmental disasters, such as the serious haze caused by heavy air pollution in northern China and across the Yangtze River ...

Fossil skull connects continents

A fossil skull discovered in Israel's Manot Cave provides strong evidence of the first modern human migration to Europe, dating back 55,000 years. The analysis reveals a close genetic relationship between ancient Europeans and modern humans from Africa, challenging previous theories about the origins of European modern humans.

Dartmouth investigators conduct systematic testing of deimmunized biotherapeutic agents

The Dartmouth team created a systematic testing platform to analyze deimmunized protein design space. Their analysis revealed that experimentally measured molecular fitness mapped closely onto the computational design space for 18 deimmunized drug candidates, demonstrating potential to predict and design tradeoffs between immunogenicit...

Smothered oceans

A study from the University of California, Davis reveals extreme oxygen loss in oceans around 10,000-17,000 years ago, coinciding with past global climate change. The findings suggest that modern oceans are moving into a state with no precedent in human history.

The 2 faces of Mars

A massive celestial object impacted Mars, generating a magma ocean that solidified into the mountainous highlands of the southern hemisphere. This event, occurring around 4-15 million years after Mars' formation, is believed to have triggered volcanic activity and changed the planet's magnetic field.

DFG to fund 4 new clinical trials

The DFG is funding four new clinical trials addressing urgent questions in patient-oriented research, including surgery for metastatic stomach cancer and individualised chemotherapy for certain breast cancers. Over 1,160 patients will participate in the trials, which will test efficacy of new procedures over a three-year period.
