    The expansion of grasslands isn't solely due to drought, but more complex climate factors are at work, both for modern Africans now and ancient Africans in the Pleistocene, suggests new research.
  • Glycans as biomarkers for cancer?
    Glycosylated proteins are often overexpressed in tumor cells and thus could serve as tumor markers, especially those with the interesting molecule sialic acid as their sugar moiety. Scientists now report on a bioorthogonal labeling test for sialylated glycoproteins based on a glycoproteomics approach. This assay not only assesses the level of sialylated glycans in the tumor cell membranes, but also identifies up- or downregulated proteins directly in the prostate cancer tissue.
  • Microbe mystery solved: What happened to the Deepwater Horizon oil plume?
    The Deepwater Horizon oil spill in the Gulf of Mexico in 2010 is one of the most studied spills in history, yet scientists haven't agreed on the role of microbes in eating up the oil. Now a research team has identified all of the principal oil-degrading bacteria as well as their mechanisms for chewing up the many different components that make up the released crude oil.
  • Computer model simulates sense of touch from the entire hand
    Neuroscientists have developed a computer model that can simulate the response of nerves in the hand to any pattern of touch stimulation on the skin. The tool reconstructs the response of more than 12,500 nerve fibers with millisecond precision, taking into account the mechanics of the skin as it presses up against and moves across objects.
  • Brains evolved to need exercise
    Mounting scientific evidence shows that exercise is good not only for our bodies, but for our brains. Yet, exactly why physical activity benefits the brain is not well understood. Researchers suggest that the link between exercise and the brain is a product of our evolutionary history and our past as hunter-gatherers.
  • Lightning Sparking More Boreal Forest Fires
    A new study finds lightning storms were the main driver of recent massive fire years in Alaska and northern Canada, with the storms likely to migrate north as climate warms.
  • Where are the new therapies for heart disease?
    Despite dramatic reductions in the death rate from cardiovascular disease, which includes heart disease and stroke, it remains the leading causes of death, and experts have expressed concern that the number of new therapies coming to market has lagged.
  • Early antiretroviral therapy linked with bone loss in patients with HIV
    Current HIV treatment guidelines now recommend initiating antiretroviral treatment (ART) at the time of diagnosis. However, a new study has found that such early ART causes greater bone loss compared with deferring ART.
  • A little place for my stuff: How big bacteria can grow depends on how much fat they can make
    Just as people endlessly calculate how to upsize or downsize, bacteria continually adjust their volume (their stuff) to fit inside their membrane (their space). But what limits their expansion? The answer will surprise you.
  • Air pollution casts shadow over solar energy production
    Global solar energy production is taking a major hit due to air pollution and dust.

    Billions of pieces of plastic are floating in the oceans. Their effects are also sufficiently well-known: marine animals swallow them or get tangled up in them, which can cause them to die in agony. On the other hand, we know less about the consequences of the smallest pieces of plastic, known as microplastics. Researchers have now started to investigate how microplastics are generated and where they actually come from.
  • New experimental and theoretical approaches 'dive into the pool' of membranes organelles
    Engineers have developed a new way to dive into the cell's tiniest and most important components. What they found inside membraneless organelles surprised them, and could lead to better understanding of fatal diseases including cancer, Huntington's and ALS.
  • Premature infants at greater risk of SIDS
    Premature infants still have a greater risk compared to full-term babies of dying of SIDS and other sleep-related infant deaths despite recommendations from the American Academy of Pediatrics that hospital NICU's provide more safe infant sleep education to parents before they go home.
