• New measurement will help redefine international unit of mass

  30-06-2017 23:44
  
  Using a state-of-the-art device for measuring mass, researchers at the National Institute of Standards and Technology (NIST) have made their most precise determination yet of Planck's constant, an important value in science that will help to redefine the kilogram, the official unit of mass in the SI, or international system of units. Accepted for publication in the journal Metrologia, these new results come ahead of a July 1 international deadline for measurements that aim to redefine the entire

• Team accelerates rendering with AI

  Modern films and TV shows are filled with spectacular, computer-generated sequences which are computed by rendering systems that simulate the flow of light in a 3D scene. However, computing many light rays is an immensely labor-intensive and time-consuming process. The alternative is to render the images using only a few light rays, but this shortcut results in inaccuracies that show up as objectionable noise in the final image.

• Mistaken identity of East Asian vine species resolved after 100 years

  New light has been shed on a misclassified vine species in the Ryukyu Islands of East Asia. This plant was first discovered in 1917 in Taiwan, when it was provisionally identified as Kadsura japonica. The plant was recently spotted again after 100 years, and further investigation proved that it was in fact a different species: Kadsura matsudae. The findings were published on June 30th in the online edition of Phytotaxa.

• New insight into how telomeres protect cells from premature senescence

  30-06-2017 16:19
  
  Researchers at the Institute of Molecular Biology (IMB) and Johannes Gutenberg University Mainz (JGU) have further uncovered the secrets of telomeres, the caps that protect the ends of our chromosomes. They discovered that an RNA molecule called TERRA helps to ensure that very short (or broken) telomeres get fixed again. The work, which was recently published in the journal Cell, provides new insights into cellular processes that regulate cell senescence and survival in ageing and cancer.

• Colon cancer nuclear pore dynamics are captured by HS-AFM

  30-06-2017 16:04
  
  One of the key reasons for cancer mortality is the highly invasive behaviour of cancer cells, which is often due to aggressive metastasis. Metastasis is facilitated by various growth factors and cytokines secreted from cells of the immune system, which operate through various signaling pathways. Remarkably, these signaling pathways enter the nucleus through the nuclear pore complex (NPC), which is supposed to act as a doorkeeper to the nucleus. NPC is, in fact, a nanomachine consisting of multip

  As the climate change progresses, droughts are expected to become more and more common and more intense in Europe, as in many parts of the globe. However, many plants are not able to handle this kind of climate. This includes the Norway spruce, which is Germany's most important commercial tree species and accounts for the majority of trees in the Black Forest.

• How do impurities move in tungsten?

  30-06-2017 15:21
  
  One part of the vacuum vessel (the plasma facing material) of the fusion experimental device and future fusion reactor comes into contact with plasma. When the plasma ions enter into the material, those particles become a neutral atom and stay inside the material. If seen from the atoms that compose the material, the plasma ions that entered become impurity atoms. The impurity atoms migrate slowly in interspaces among the atoms that composes the material and eventually, they diffuse inside the m
