BBC News: Quick Guide: Cloning  Succinct sections on key aspects of cloning

BBC online art gallery  The Science and Art slideshow is one of five slideshows produced specially to give teachers ideas about how to use Your Paintings in the classroom.  Your Paintings brings together paintings owned by public galleries in the UK. As the paintings are in public ownership, ultimately everyone living in the UK owns this vast collection.  As well as containing many portraits of important scientists, Your Paintings can be used as a starting point for pupils to make scientific investigations of their own.

Part 2 of 2. David Attenborough explains how early sea life developed and adapted to dry land, becoming Reptiles and Amphibians. After the era of the Dinosaurs came to a sudden end, Mammal species began to proliferate. From BBC 1 documentary 'Charles Darwin and the Tree of Life'.

Humans may in part owe their big brains to a DNA "typo" in their genetic code, research suggests. The mutation was also present in our evolutionary "cousins" - the Neanderthals and Denisovans. However, it is not found in humans' closest living relatives, the chimpanzees. As early humans evolved, they developed larger and more complex brains, which can process and store a lot of information. Last year, scientists pinpointed a human gene that they think was behind the expansion of a key brain region known as the neocortex.

A local delicacy in north-east Thailand, made from raw fish, has been found to be behind a high incidence of liver cancer in the area, and doctors are trying to educate people about the risk.

The treatment used olfactory ensheathing cells (OECs) - specialist cells that form part of the sense of smell. OECs act as pathway cells that enable nerve fibres in the olfactory system to be continually renewed. In the first of two operations, surgeons removed one of the patient's olfactory bulbs and grew the cells in culture. Two weeks later they transplanted the OECs into the spinal cord, which had been cut through in the knife attack apart from a thin strip of scar tissue on the right. They had just a drop of material to work with - about 500,000 cells.

The parasitic and apparently tasty honey fungus not only divides opinions; it is also widely seen as the largest living organism on Earth. More precisely, a specific honey fungus measuring 2.4 miles (3.8 km) across in the Blue Mountains in Oregon is thought to be the largest living organism on Earth.

A new treatment for pancreatic cancer could significantly increase survival rates, Ulster University has claimed. It said the treatment could lead to a five-fold reduction in tumour size. It involves injecting tumours with oxygen micro bubbles that are coated with a drug which is then activated by ultrasound.

Sharmila Nikapota, the mother of a child with a rare genetic disorder, has high hopes for gene editing. "For us this technology holds the unimaginable dream of a cure," she says. Her 13-year-old daughter Sohana has spent her entire life covered in painful blisters, the result of a condition called recessive dystrophic epidermolysis bullosa.

If the lab technique works in the field, it could offer a new way of stopping the biting insects from spreading malaria to humans, they say. The scientists put a new "resistance" gene into the mosquito's own DNA, using a gene editing method called Crispr. And when the GM mosquitoes mated - their offspring inherited the same resistance, PNAS journal reports. In theory, if these mosquitoes bite people, they should not be able to pass on the parasite that causes malaria.

Researchers analysed the genomes of 51 individuals who lived between 45,000 years ago and 7,000 years ago. The results reveal details about the biology of these early inhabitants, such as skin and eye colour, and how different populations were related. It also shows that Neanderthal ancestry in Europeans has been shrinking over time, perhaps due to natural selection. The study in Nature journal shines a torchlight over some 40,000 years of prehistory, showing that ancient patterns of migration were just as complex as those in more recent times.

Researchers tested pairs of identical and non-identical twins to see how attractive they were to mosquitoes. Identical twins were more likely to have similar levels of attractiveness - suggesting shared genetic factors were at play. The "intriguing" results must now be assessed in larger trials, experts say. Researchers have long tried to understand what drives mosquitoes to bite certain people more than others. Recent work shows the insects may be lured to their victims by body odour.
