Hidden role of ‘cell protector’ opens cancer treatment possibilities
Landmark research on MCL-1, a critical protein that is an attractive target for cancer drug development, helps explain why some promising cancer treatments are causing serious side effects, and offers a roadmap for designing safer, more targeted therapies.
The WEHI-led discovery, published in Science, has uncovered a critical new role for MCL-1, revealing it not only prevents cell death but also provides cells with the energy they need to function.
The findings reshape our understanding of how cells survive and thrive, with implications for both cancer treatment and developmental biology.
Is Earth inside a huge void? ‘Sound of the Big Bang’ hints at possible solution to Hubble tension
Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say.
Their theory is a potential solution to the “Hubble tension” and could help confirm the true age of our universe, which is estimated to be around 13.8 billion years old.
The latest research —shared at the Royal Astronomical Society’s National Astronomy Meeting (NAM 2025) at Durham University—shows that sound waves from the early universe, “essentially the sound of the Big Bang,” support this idea.
Meteorite challenges the timeline of the early solar system
A small, inconspicuous meteorite may be about to change our understanding of how and when our solar system formed. Tiny shavings from the meteorite Northwest Africa 12264 are challenging the long-held belief that planets near the sun formed earlier than those beyond the asteroid belt, between Mars and Jupiter.
Solid catalyst breaks the rules: Oxygen evolution steps can happen simultaneously
Oxygen evolution is considered one of the most energy-intensive steps in water electrolysis and is therefore a key factor for more efficient green hydrogen production. Modeling of the reaction mechanisms has so far been based on the assumption that the elementary steps take place sequentially and not in a concerted manner.
A team led by Prof. Dr. Kai S. Exner from the University of Duisburg-Essen has now shown that this assumption is not always correct. The results, published in Nature Communications, open up new possibilities for improving solid catalysts for energy conversion and storage applications.
There are two basic types of catalysis: homogeneous catalysts have the same physical state as the substances being converted (e.g., they all are liquid), while heterogeneous catalysts are in a different phase, for example a solid that reacts with liquids or gases. For a reaction to take place on the surface of a solid catalyst, the starting materials (reactants) must attach to its surface (adsorption) and then dissolve again after the reaction has taken place (desorption).
Scientists uncover ‘superfamily’ of bacterial predator proteins
Scientists have identified a new type of protein in bacteria that could change our understanding of how these organisms interact with their environments.
A new study, published in Nature Communications, focuses on a protein called PopA, found in the bacterial predator Bdellovibrio bacteriovorus. The protein forms a unique fivefold structure, unlike the usual single or three-part structures seen in similar proteins.
An international research team, led by University of Birmingham scientists, used advanced imaging techniques to reveal that PopA has a bowl-like shape that can trap parts of the bacterial membrane inside it.
An approach to realize heralded photon storage in a Rydberg superatom
Quantum technologies, systems that operate leveraging quantum mechanical effects, have the potential to outperform classical technologies in some specific tasks. Over the past decades, some researchers have also been trying to realize quantum networks, systems comprised of multiple connected quantum devices.
So far, photons have been the most widely used particles for carrying quantum information across different devices in quantum networks. The main reasons for this are that photons can travel at remarkable speeds, while weakly interacting with their surrounding environment, which helps to preserve the quantum states they are carrying.
To successfully employ photons in quantum networks, however, physicists and engineers need to be able to confirm that they are stored successfully without destroying them.
