Apes suffer from self-doubt too
Just like humans, apes are sufficiently self-aware to doubt their own knowledge, says a new study.As part of the research, Josep Call of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, put food in one of two opaque plastic pipes and had watching bonobos, chimpanzees, gorillas and orangutans pick the one with the food.
Call found that if they were made to wait, the apes sometimes forgot where the food was, but by and large they did well on the task.

To find out if the apes doubted their own decisions, Call gave them the option to peek into the end of the pipes before they chose one.He found that the apes were more likely to check the pipes if they had to wait before picking one.Call says this suggests that the apes had begun to doubt their memory.

Remains found in Southwell could be Roman temple
Archaeologists have unearthed what they say could be the remains of an unknown Roman temple in Nottinghamshire.

Walls, ditches and ornate stones were revealed after excavations on the Minster C of E School site in Southwell between September 2008 and May 2009.Ursilla Spence from Nottinghamshire County Council, the archaeologist who supervised the work, and colleagues say their analysis of the shape and quality of the remains suggest it could have been an important place of worship.

This could mean Southwell enjoyed a high status Roman Britain, the researchers added.
A wall of large block masonry that was probably plastered and possibly painted, with a ditch that may have contained water, was possibly the boundary of a large temple.
The researchers also discovered the remains of timber scaffolding for the wall. Radiocarbon dating of this dated it to the first century.Ursilla said a lack of domestic remains, like pots and tools, also indicated a ceremonial use.

“This is a fascinating site. But, so far, it has raised more questions than it has answered,” she said.“I hope that future excavation work, when the site is developed, will throw more light on exactly what was going on here 2,000 years ago.”

“But, whatever we might find in future, I believe we have already shown that Roman Southwell was a much more significant place than anyone previously thought,” she added.

New hope in fight against leukaemia
British scientists have offered new hope to those with end-stage leukaemia, a cancer of the blood or bone marrow.The researchers say that a life-saving cancer treatment that uses the body’s own immune system to heal itself could be available within 10 years.
The treatment, known as TCR gene therapy, works by injecting white blood cells with an infection-fighting gene that recognises cancer cells.

The white blood cells, which make up the body’s immune system, then destroy leukaemia cells.However, experts feared the white blood cells would attack other healthy cells causing a condition called graft versus host disease (GVHD). But the study’s lead author Dr Gavin Bendle at The Netherlands Cancer Institute and colleagues found a way to overcome GVHD after a series of experiments.
