Malfunction in spermatogenesis
Malfunction in spermatogenesis
Bonn researchers uncover contribution of Cylicin proteins to male fertility For successful fertilization, sperm should move forward rapidly and be shaped correctly. The unique structure of the sperm cells forms during spermiogenesis. Now, researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research Unit "Life & Health" at the University of Bonn have found that fertility problems in both mice and humans can be caused by loss of so-called cylicines.

Growing microtumors in a dish helps rapidly identify genes that drive tumor growth
Researchers have identified a new way to screen genes that cause several different types of cancers to grow, identifying particularly promising targets for precision oncology in oral and esophageal squamous cancers. The study, published in this month's issue of Cell Reports , used 3-dimensional models of organ tissues called organoids to identify and test potential gene targets from The Cancer Genome Atlas.

Pioneering research method reveals bluefin tuna's fate
Pioneering research method reveals bluefin tuna’s fate
The return of bluefin tuna to Northern European waters is a conservation success story, but rising sea temperatures in their Mediterranean nursery grounds mean this recovery may be short-lived, according to new research led by the University of Southampton. Temperatures expected in the Mediterranean within the next 50 years are expected to drive juvenile tuna out of the Mediterranean, where they may be accidentally caught in existing sardine and anchovy fisheries - requiring fishery managers to adapt their methods to allow tuna nurseries to establish.

World’s first transatlantic flight on 100% sustainable aviation fuel takes off
The world's first transatlantic flight run on 100% sustainable aviation fuel is taking off today from London Heathrow, bound for New York. The Virgin Atlantic Boeing 787 flight, which is taking off on 28 November 2023 from London Heathrow (LHR) to New York John F Kennedy Airport (JFK), is the first to showcase the feasibility of flying on 100% sustainable aviation fuel (SAF) over such a distance.

Early Humans in the Paleolithic Age: More Than Just Game on the Menu
Early Humans in the Paleolithic Age: More Than Just Game on the Menu
In a study published in the journal "Scientific Reports," researchers from the Senckenberg Centre for Human Evolution and Palaeoenvironment (SHEP) at the University of Tübingen show that early humans of the Middle Paleolithic had a more varied diet than previously assumed. The analysis of a site in the Zagros Mountains in Iran reveals that around 81,000 to 45,000 years ago, the local hominins hunted ungulates as well as tortoises and carnivores.

Fat cells help repair damaged nerves
Fat cells help repair damaged nerves
Damage to the body's peripheral nerves can cause pain and movement disorders. Researchers at the Leipzig University have recently investigated how damaged nerves can regenerate better. They found that fat tissue strongly supports the Schwann cells needed for repair during the healing process. The results were published in the renowned journal "Cell Metabolism".

The world needs more empathy-here is how science can harness it
McGill researchers explore the power of imagination, showing how a shift in thinking can make humans more caring In a world grappling with deep-seated division and social upheaval, empathy has become more critical than ever. But science suggests when it comes to evoking empathy, our imagination is more powerful than we previously thought.

Entanglement to the Rescue
In the search for new particles and forces in nature, physicists are on the hunt for behaviors within atoms and molecules that are forbidden by the tried-and-true Standard Model of particle physics. Any deviations from this model could indicate what physicists affectionately refer to as "new physics." Caltech assistant professor of physics Nick Hutzler and his group are in pursuit of specific kinds of deviations that would help solve the mystery of why there is so much matter in our universe.

A new way to see the activity inside a living cell
A new way to see the activity inside a living cell
Massachusetts Institute of Technology Using fluorescent labels that switch on and off, MIT engineers can study how molecules in a cell interact to control the cell's behavior. Living cells are bombarded with many kinds of incoming molecular signal that influence their behavior. Being able to measure those signals and how cells respond to them through downstream molecular signaling networks could help scientists learn much more about how cells work, including what happens as they age or become diseased.
