| World’s first ciliary stroke motion microrobots Posted: 31 Aug 2016 08:10 AM PDT Scientists have developed microrobots with high propulsion efficiency in highly-viscous fluid environments, applying propulsion techniques that mimic the ciliary stroke motion of paramecia. |
| Invisibility cloak with photonic crystals Posted: 31 Aug 2016 08:10 AM PDT Almost as elusive as unicorns, finding practical materials for invisibility cloaking is challenging. Researchers have new ideas how to solve that. They're using crystal "atoms" made of dielectric rods called photonic crystals. |
| The genesis project: New life on exoplanets Posted: 31 Aug 2016 05:56 AM PDT Can life be brought to celestial bodies outside our solar system which are not permanently inhabitable? This is the question with which experts are dealing in a recent essay. |
| Ethical concerns tied to research on human-animal embryos Posted: 30 Aug 2016 11:38 AM PDT Scientists have developed a new bioethical framework for addressing concerns surrounding potentially revolutionary research on human-animal embryos. |
| Cannabinoid receptor activates spermatozoa Posted: 30 Aug 2016 09:17 AM PDT Biologists have detected a cannabinoid receptor in spermatozoa. Endogenous cannabinoids that occur in both the male and the female genital tract activate the spermatozoa: they trigger the so-called acrosome reaction, during which the spermatozoon releases digestive enzymes and loses the cap on the anterior half of its head. Without this reaction, spermatozoa cannot penetrate the ovum. |
| Trapped in a nuclear weapon bunker wood ants survive for years in Poland Posted: 30 Aug 2016 08:37 AM PDT Having built their nest over the vertical ventilation pipe of an old nuclear weapon bunker in Poland, every year a large number of wood ants fall down the pipe to never return to their colony. Curiously, the ants have already upped their numbers to these of big natural colonies, while carrying on with their basic activities of nest maintenance, constructing and molding. |
| Anomalous grooves on Martian moon Phobos explained by impacts Posted: 30 Aug 2016 08:32 AM PDT Some of the mysterious grooves on the surface of Mars' moon Phobos are the result of debris ejected by impacts eventually falling back onto the surface to form linear chains of craters, according to a new study. One set of grooves on Phobos are thought to be stress fractures resulting from the tidal pull of Mars. The new study addresses another set of grooves that do not fit that explanation. |
| Systems biology research study reveals benefits of vacation, meditation Posted: 30 Aug 2016 06:18 AM PDT Scientists used a rigorous study design to assess the biological impact of meditation compared to vacation. The researchers found that a resort vacation provides a strong and immediate impact on molecular networks associated with stress and immune pathways, in addition to short-term improvements in well-being, as measured by feelings of vitality and distress. A meditation retreat, for those who already used meditation regularly, was associated with molecular networks characterized by antiviral activity. The molecular signature of long-term meditators was distinct from the non-meditating vacationers. |
