    Key to the high aggressiveness of pancreatic cancer identified

    Pancreatic cancer is one of the most aggressive cancers and has one of the lowest survival rates — only 10% after five years. One of the factors contributing to its aggressiveness is its tumor microenvironment, known as the stroma, which makes up the majority of the tumor mass and consists of a network of proteins and different non-tumor cells. Among these, fibroblasts play a key role, helping tumor cells to grow and increasing their resistance to drugs. Now, a study led by researchers from…

    Artificial skin from hydrogels | ScienceDaily

    The skin is the largest organ in the human body. It makes up around 15 percent of our body weight and protects us from pathogens, dehydration and temperature extremes. Skin diseases are therefore more than just unpleasant — they can quickly become dangerous for affected patients. Although conditions such as skin cancer, chronic wounds and autoimmune skin diseases are widespread, we often still don’t fully understand about why they develop and how we can treat them effectively.

    To find…

    By Haidar Eid  

    Nobody can prevent the BDS movement from expressing principled criticism of any form of normalization with apartheid Israel.

    Sometimes, criticism, both constructive and destructive, is directed at the BDS movement, particularly the Palestinian Campaign for the Academic and Cultural Boycott of Israel (PACBI). The accusations…

  • Researchers have mapped the hidden control system of vision

    Researchers have mapped the hidden control system of vision

    For the first time, the smallest control system of vision in mammals has been mapped — a discovery that opens entirely new insights into how our vision works and how it can be affected by disease.

    Vision is one of the most complex functions of our brain and requires a seamless interaction between many different brain structures to decode shapes, colours, depths, and movements and turn them into a meaningful whole. Just like other brain functions, vision also depends on a balanced and…

  • Machine learning unlocks superior performance in light-driven organic crystals

    Machine learning unlocks superior performance in light-driven organic crystals

    Researchers have developed a machine learning workflow to optimize the output force of photo-actuated organic crystals. Using LASSO regression to identify key molecular substructures and Bayesian optimization for efficient sampling, they achieved a maximum blocking force of 37.0 mN — 73 times more efficient than conventional methods. These findings could help develop remote-controlled actuators for medical devices and robotics, supporting applications such as minimally invasive surgery and…

    Uncovering the molecular drivers of liver cancer

    Researchers discover that inflammation and aging contribute to non-viral liver cancer development. Green tea’s role in reversing some of the pathway dysregulation that may contribute to the cancer development and other therapies explored.

    Liver cancer can arise spontaneously from healthy liver tissue. Recently, however, researchers have discovered an increasing correlation between some liver cancers and non-viral chronic liver disease (CLD).

    One liver cancer, hepatocellular carcinoma (HCC),…

  • France expels 12 Algerian officials as tensions escalate | Politics News

    France expels 12 Algerian officials as tensions escalate | Politics News

    Move comes after Algeria expelled French diplomats, following France’s arrest of an Algerian consular official linked to an alleged kidnap.

    France says it will expel 12 Algerian diplomatic and consular staff members and has recalled its ambassador from Algiers, deepening a crisis that threatens to unravel months of attempted reconciliation between the two countries.

    The announcement on Tuesday comes a day after Algeria ordered 12 French diplomats to leave within 48 hours.

    Algiers announced…

  • How circadian clocks maintain robustness in changing environments

    How circadian clocks maintain robustness in changing environments

    New research has uncovered how a simple circadian clock network demonstrates advanced noise-filtering capabilities, enhancing our understanding of how biological circuits maintain accuracy in dynamic natural environments.

    The study highlights the remarkable ability of biological clocks to adapt to environmental fluctuations while maintaining their accuracy. The findings have implications for understanding how organisms — from bacteria to humans — track time in response to external changes…

    Taste research suggests pearl millet could be a healthy, sustainable, gluten-free wheat alternative in the US

    With droughts in the United States increasingly impacting wheat production, many producers are looking for more durable alternatives. Researchers from Drexel University, the University of Pennsylvania, City University of New York and Monell Chemical Senses Center recently reported that American palates are likely to accept pearl millet — a hardy, gluten-free grain that has been cultivated for centuries in rugged, drought conditions in Africa and India — as an acceptable substitute in…

    Preventing onset and development of heart failure with preserved ejection fraction

    An international team of researchers at the University of Manchester, Baylor College of Medicine and collaborating institutions has discovered a natural mechanism that protects the heart from heart failure with preserved ejection fraction (HFpEF), a serious condition in need of effective treatment. The team reports in Circulation, a journal of the American Heart Association, that when the cardioprotective mechanism fails, it promotes the development of HFpEF. Importantly, restoring the…
