• 00:30 Elusive Z- DNA found on nucleosomes

  Read the story at ScienceDaily
  New research shows that left-handed Z-DNA, normally only found at sites where DNA is being copied, can also form on nucleosomes. The structure of DNA which provides the blueprint for life has famously been described as a double helix. To save space inside the nucleus, DNA is tightly wound around proteins to form nucleosomes which are then further wound and compacted into chromatin, which is further compacted into chromosomes. But this familiar image of a right handed coil (also called B-DNA) is not the only form of DNA. At sites where DNA is being copied into RNA (the messenger which is used as the instruction to make proteins) the DNA needs to unwind, and, in a process of negative supercoiling, can form a left-handed variety of the DNA double helix (Z-DNA).

• 00:30 Rare Miller's grizzled langur rediscovered in Borneo

  Read the story at ScienceDaily
  Scientists have found one of the rarest and least known primates in Borneo, Miller’s Grizzled Langur, a species which was believed to be extinct or on the verge of extinction. The findings confirms the continued existence of this endangered monkey and reveals that it lives in an area where it was previously not known to exist.

• 00:30 T-rays technology could help develop Star Trek-style hand-held medical scanners

  Read the story at ScienceDaily
  Scientists have developed a new way to create Terahertz waves (T-rays) that may one day lead to biomedical detective devices similar to the 'tricorder' scanner used in Star Trek.

• 00:29 Anti-infective drug shortages pose threat to public health and patient care

  Read the story at ScienceDaily
  Shortages of key drugs used to fight infections represent a public health emergency and can put patients at risk, according to a new review. Frequent anti-infective shortages can substantially alter clinical care and may lead to worse outcomes for patients, particularly as the development of new anti-infectives has slowed and the prevalence of multidrug-resistant pathogens is increasing.

• 00:29 Bucky balls for next-generation spintronics devices

  Read the story at ScienceDaily
  The beauty of an electron’s spin is that it responds very rapidly to small magnetic fields. Such external magnetic fields can be used to reverse the direction of spin. In this way, information can be carried by a flow of electrons.

• 00:29 Dual-earner families: Mum and Dad share the workload, Norwegian study suggests

  Read the story at ScienceDaily
  For the first time research is being carried out on the degree to which dual-earner families in Norway share paid and unpaid work. It is a key aim of Norwegian policy to promote an equal distribution of paid and unpaid work among dual-earner couples with children. The researchers conclude that roughly 40 per cent of the couples have a gender-equal relationship in that the mother and the father share both unpaid and paid work equally.

• 00:29 Using Hollywood technology to unlock the secret of pianist's sounds

  Read the story at ScienceDaily
  University of Southampton academics are pioneering a new way of using motion capture technology to examine the way pianists play the piano. By using a unique kinematic measurement technique, known as HAWK (Hand And Wrist Kinematics), researchers will be able to look at individual pianists' playing technique - giving an insight into the posture of their hands on the keys and the movements they use - hopefully showing how this translates into the unique sound they create.

• 00:29 Why do smells make some people sick?

  Read the story at ScienceDaily
  Do you get a headache from the perfume of the lady next to you at the table? Do cleaning solutions at work make your nose itch? If you have symptoms prompted by everyday smells, it does not necessarily mean you are allergic but rather that you suffer from chemical intolerance. This hypersensitivity can be the result of an inability to get used to smells.
