Recently, the a fossil of a Ornithomimus dinosaur was found with preserved skin and feather structures, helping confirm the long-standing theory that some dinosaurs had feathers. The feather and skin patterns also help give insight into how these dinosaurs may have regulated their body temperatures.

Continuing with the fossil-related news, a new study proposed that limb-regeneration was ubiquitous in the ancestors of modern tetrapods. This means that this ability has likely been lost in most current tetrapod lineages. Keeping this evolutionary information in mind may lead to a better understanding of limb regeneration and why humans are not capable of this.

Antibiotic resistance is a problem in modern medicine, and one that threatens to undo all of the progress modern medicine has had regarding infectious disease. There are many different approaches to this problem, but a new approach harnessing currently used antibiotics and antibodies has proved very successful in rats, although it remains to be seen how successful it may be in humans.

A cure for jetlag? Researchers in Austria have found that, if you can stomach it, a blood transfusion could alleviate symptoms of jet lag. It appears that a lack of sleep has a severe effect on red blood cells, so replenishing them should help reverse the effects of jet lag! On a serious note, this could potentially be very useful for shift workers, where incidences of heart disease are higher.

Meningitis and starting university. If you are starting university or even returning, it is important you know about meningitis, and how to recognise the symptoms – it could save a life. Common symptoms can include:

  • Fever with cold hands and feet
  • Vomiting
  • Severe muscle pain
  • Severe headache
  • Sensitive to bright lights
  • A distinctive rash
  • Drowsiness and difficulty waking up

The importance of iron-oxidising bacteria. A new study has indicated that iron-oxidising bacteria probably sustained the global carbon cycle prior to oxygen dependent species arising.

Meet our new cousin: Homo naledi

Something very exciting happened this year. We heard the announcement of a new species – quite ancient but closely related to our very own species: the Homo naledi.

In October 2013, two recreational covers (Rick Hunter and Steven Tucher) happened upon some fossil bones within a cave, known as the Dinaledi chamber, located within the Gauteng province of South Africa.
