Mikroplastik - ein unsichtbarer Störenfried - Holm - 2013 - Biologie in unser... - 0 views

    "Plastic is produced in large amounts and used for various purposes. After use, huge amounts end up in the enviroment, often in the oceans. There, fragmentation leads to small particles, called microplastics. By filtrating and benthos-feeding organisms it can be inadvertently taken up as food. We demonstrate that the unicellular ciliate Paramecium, the freshwater flea Daphnia and the blue mussel Mytilus took up microplastic particles. Even more, in Mytilus, the plastic particles were transported into the digestive gland and accumulated in the respective cells. Subsequently, pathological alterations in the gland were noted. Microplastics are of concern because animals might starve with a full belly after uptaking large amounts of microplastics. As well, particles with sharp edges can injure the mucous layer of the gastrointestinal tract. Furthermore, persistent organic pollutants adhere at plastic and thus, may cause adverse impacts on the animal. We show options for solutions and indicate selected organisations working on the development of solution"

Short Sharp Science: Half a heartbeat changes our response to scary images - 0 views

  •  
    In another study, in which volunteers saw the same pictures while having their brain scanned using MRI, she found that people had a stronger response in the hippocampus and amygdala - areas of the brain associated with fear - when they were shown fearful faces at systole than when they saw them at diastole. In other words, half a heartbeat was all it took for a person to experience a significantly different response to the same scary stimulus.

Grassroots Nanotech: Controlled Self-Assembly - 0 views

  •  
    Throughout our history, mankind has created tools the same way, essentially using the top-down approach. Think about it. In the stone age, a sharp cutting tool was fashioned by using a larger stone to chip away pieces until the cutting stone was sharp enough. Today, a computer chip is made by a large laser that etches the circuits into a piece of silicon.

Short Sharp Science: Smallpox finding prompts HIV 'whodunnit' - 0 views

  •  
    People keep blaming the emergence of HIV on science, or at least medicine. For the longest time this came in the form of the claim that it was all due to contaminated polio vaccine. That turned out to be factually groundless. Now a group of scientists in the US thinks it may all be down to the greatest medical intervention of all: the eradication of smallpox.

    "A more potentially useful observation about HIV and viruses comes from Jennifer Smith of the University of North Carolina in Chapel Hill and colleagues in the 1 June issue of the Journal of Infectious Diseases, in which they report that men with HPV infection on their penis are nearly twice as likely to catch HIV than men without. They suspect the virus - which causes cervical cancer in women, and genital warts in men and women - attracts lymphocytes to the skin of the penis for HIV to infect, or creates micro-lesions where it can enter. That's good news, because we have a vaccine for HPV that appears to be completely safe. The team calculates that vaccinating men against HPV could prevent as many cases of HIV as more widely hailed circumcision efforts. It just goes to show that vaccination - already one of the biggest success stories of medicine - can continue to throw up unexpected benefits."
