Controlling cells with a laser beam

Researchers at TU Wien develop a method to guide individual cells with laser precision, enabling reproducible production of artificial tissue and testing new drugs without animal testing. The technique involves adding special molecules to hydrogel surrounding cells, which become softer and more permeable when activated by a laser beam.

When AI is the inventor – who gets the patent?

Academics argue AI systems like DABUS need new IP laws as existing ones are inadequate to deal with cases where machines are named sole inventors. The authors recommend introducing a new 'AI-IP' form of law that would be specifically tailored to AI-generated inventiveness, addressing ownership and novelty issues.

Bringing magma up to our feet—Just add CO2

A University of Utah and New Zealand study reveals that CO2 deep underground allows magma to avoid being trapped, reaching the surface and pooling into persistent lava lakes. This finding expands our understanding of magma sources and transport to the surface, particularly in rift volcanoes.

Ostriches can adapt to heat or cold – but not both

Research at Lund University found that ostriches are sensitive to fluctuating temperatures and lay up to 40% fewer eggs if the temperatures rise or fall by 5 degrees. The study also revealed a genetic trade-off between heat and cold tolerance, meaning that increased heat tolerance comes at the cost of decreased cold tolerance.

When blue-green algae get a virus

A recent study found that viral infections can significantly impact cyanobacterial populations, which produce half the world's oxygen. Researchers discovered a 2017 outbreak in the North Pacific Ocean, where Prochlorococcus populations declined by 17°C due to increased viral infection.

A new ultra-thin electrode material: A step closer to next-generation semiconductors

A new ultra-thin electrode material has been developed to control the electrical properties of two-dimensional semiconductors. This breakthrough enables the creation of high-performance logic circuits with improved power efficiency, paving the way for next-generation system technologies like artificial intelligence.

What happened to marine reptiles before the mass extinction at the end of the Cretaceous?

A study by researchers at the University Liège has unravelled the evolution of mosasaurs in the late Cretaceous, revealing a decline in morphological diversity and ecological innovations in certain regions. The research uses high-resolution 3D scans of mosasaur skulls to draw precise conclusions about their hunting and movement abilities.
