Pleasing to the eye

Scientists found that visually stimulating female Houbara bustard brooders with highly displaying male birds increased their fertility and breeding success. This led to better offspring growth rates due to increased testosterone allocation, suggesting a potential means for conserving vulnerable species.

Consequences of being rich

A new study found that wealth and population density are the primary factors driving invasive species in Europe, surpassing climate and geography. Human activities like trade and travel have led to a surge in introduced species, causing ecosystem disruption and native species displacement.

Politics are a key factor in biodiversity

A new atlas highlights the critical role of politics in driving biodiversity loss, emphasizing the need for policy reforms to reduce pressure on biodiversity. The atlas combines key research findings from a major European project and provides recommendations for policymakers and conservationists.

PRACE research infrastructure inaugurated

The PRACE partnership has established a persistent pan-European High Performance Computing research infrastructure, providing computing power of several Petaflop/s. The initiative aims to support European scientists and engineers in remaining internationally competitive, addressing major challenges like climate change and energy saving.

No relaxing for cancer cells

Cancer cells form clusters of centrosomes to distribute chromosomes correctly, a trick that can be targeted for destroying them. Researchers identified 82 genes responsible for this survival strategy and found that silencing specific proteins disrupts tension in spindle fibers, leading to cancer cell death.

New pathway to cheap insulin

Scientists from the Helmholtz Centre in Braunschweig, Germany, have created a new and cheaper way to produce insulin. The new method uses yeast Pichia pastoris to increase the yield of an insulin precursor, reducing costs. This breakthrough could make insulin more affordable for people in developing countries.

Fatty acid to enhance anticancer drug

Scientists have developed a fatty acid that enhances the delivery of an existing anticancer drug, increasing its effectiveness in treating certain types of blood cancer. By incorporating elaidic acid into azacytidine, researchers were able to improve the bioavailability of the agent and increase therapeutic efficacy.

How does ice flow?

Researchers from the Alfred Wegener Institute have developed a novel vibroseismic measurement method to investigate the internal structure of Antarctic ice shelves. This technique allows for more efficient and environmentally friendly data collection, enabling better forecasts of future sea level changes.

Slimming aid from the cell laboratory?

A study by the Helmholtz Association found that COX-2 inflammation enzyme increases in white fat tissue after cold exposure, stimulating the formation of brown fat cells. The scientists also discovered that boosting COX-2 production in mice leads to a 20% reduction in body weight.

A clamp for emerging flu viruses

Scientists from Freiburg and Berlin have unraveled the secret of the Mx protein, which plays a crucial role in inhibiting influenza virus replication. The Mx protein forms a ring-structured macromolecular network that restrains and deactivates viral components, providing a defense mechanism against new flu viruses.

The immune system's guard against cancer

Scientists discovered that beta-interferon inhibits tumor growth by blocking its connection to the blood circulatory system and reducing the production of growth factors. This effect was seen in mice where tumors grew slower and formed fewer metastases, highlighting a new potential target for cancer therapy.

Setting out to discover new, long-lived elements

Researchers at GSI Helmholtz Centre for Heavy Ion Research developed an ion trap device that measures atomic mass with unprecedented accuracy, enabling the discovery of long-lived elements on islands of stability. The team successfully trapped atoms of element 102, nobelium, and measured its atomic mass with a 0.000005% uncertainty.
