Multicellular algae discovered in an Early Cambrian formation

The Cambrian period, which occurred around 541–485 million years ago, is known for its explosive biological diversification. In warm oceans, the planet's earliest eukaryotes began to thrive and diversify. A major contributing factor to the acceleration of life and the development of early metazoans is thought to be an increasingly efficient food web, created largely by algae. These new...

Orioles adapt the location of their wintering grounds to weather conditions

The ability to adjust to changing environmental conditions is an essential prerequisite for species to cope with climate change. Using stable isotope analysis, a team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) now unraveled the link between wintering destinations of Eurasian Golden Oriole migrations and rainfall intensities in potential wintering grounds...

Co-production connects research and action for sustainability

Research on complex sustainability issues produces a great deal of knowledge and advice. But do these also connect to the real world? The answer may be found in co-production: don't put one researcher or computer at the helm, but rather collaboratively produce knowledge and action with a diversity of people pursuing change in the world. Scientists argue this in a new study that outlines six ways...

UK medical schools must teach about climate crisis, say students

Extreme weather events widen existing inequalities and traumatise victims while climate anxiety affects mental healthMedical students are demanding their schools include the climate crisis as a core component of the curriculum, as the intensifying climate emergency highlights the corresponding health crisis.Hannah Chase, a final year medical student at Oxford said the sense of urgency hit home...

Ecosystem responses of grassland to drought

Grassland, as one of the important ecosystems and an ecological barrier in China, is the green production base of animal husbandry. It plays a vital role in maintaining national ecological security, food security and even global ecological balance. However, climate change is expected to lead to more frequent extreme droughts in grassland regions. Yet, the underlying mechanisms of ecosystem...

Cities are making mammals bigger

A new study shows urbanization is causing many mammal species to grow bigger, possibly because of readily available food in places packed with people.

Mechanisms of resistance to drug for triple-negative breast cancer identified

Triple-negative breast cancer cells exposed to the antibody-drug conjugate sacituzumab govitecan may develop resistance to this powerful drug through alterations in both the target of the antibody and the target of the toxic payload. The findings illustrate how uncovering such mechanisms will critically inform strategies to overcome resistance to sacituzumab govitecan.
