  • Can preeclampsia be prevented? December 1, 2023
    Preeclampsia is a mysterious condition that occurs in about one of 10 pregnancies without any early warning signs. After 20 weeks or more of normal blood pressure during the pregnancy, patients with preeclampsia will begin to experience elevated blood pressure and may also have increased levels of protein in their urine due to hypertension reducing […]
  • Pathogens use force to breach immune defenses, study finds December 1, 2023
    New research has revealed a previously unknown process through which pathogens are able to defeat a cell's defense mechanisms with physical force. The discovery represents a potential game-changer in the fight against intracellular pathogens, which cause infectious diseases such as tuberculosis, malaria and chlamydia.
  • Human behavior guided by fast changes in dopamine levels December 1, 2023
    A new study shows that dopamine release in the human brain plays a crucial role in encoding both reward and punishment prediction errors. This means that dopamine is involved in the process of learning from both positive and negative experiences, allowing the brain to adjust and adapt its behavior based on the outcomes of these […]
  • To help autonomous vehicles make moral decisions, researchers ditch the 'trolley problem' December 1, 2023
    Researchers have developed a new experiment to better understand what people view as moral and immoral decisions related to driving vehicles, with the goal of collecting data to train autonomous vehicles how to make 'good' decisions. The work is designed to capture a more realistic array of moral challenges in traffic than the widely discussed […]
  • How does neonatal listeriosis impact children's health? December 1, 2023
    Maternal-fetal listeriosis is a severe disease that can lead to miscarriage, premature birth or serious neonatal infection. But what are the long-term consequences of neonatal listeriosis on the health of surviving infants?

  • Brainstorming with a bot December 1, 2023
    Electronic nanomaterials experts have imagined how recent advances in artificial intelligence (AI) and machine learning (ML) could aid scientific brainstorming and ideation. To accomplish this, they have developed a chatbot with knowledge in the kinds of science he's been engaged in.
  • How pre- and postnatal B-12 vitamins improve breast milk vitamin B-12 levels, which supports infant brain development December 1, 2023
    According to a new study B-12 vitamins increase the presence of the micronutrient in mothers' breast milk, which is especially helpful in countries where it can be difficult to eat what is needed for the body to produce B-12 naturally.
  • Scientists build tiny biological robots from human cells November 30, 2023
    Scientists have created tiny moving biological robots from human tracheal cells that can encourage the growth of neurons across artificial 'wounds' in the lab. Using patients' own cells could permit growth of Anthrobots that assist healing and regeneration in the future with no nead for immune suppression.
  • Harnessing the power of a parasite that can stop pain November 30, 2023
    For the first time, scientists have begun to figure out why the disfiguring skin lesions caused by cutaneous leishmaniasis don't hurt.
