Could Artificial Blood soon Be on Tap?

Artificial blood grown in the lab could one day be available on tap thanks to a new scientific breakthrough. According to Daily mail

Researchers used early-stage stem cells, known as immortal cells, to grow billions of red blood cells in the lab.

The new technique could one day be used to help patients with rare blood types, the researchers said.

Artificial production traditionally relies upon a type of stem cell that usually manufactures red blood cells in the human body.

Night-time urination reduced by cutting salt in diet

The need to pee at night (nocturia) -- which affects most people over the age of 60 -- is related to the amount of salt in your diet, according to new research. According to Science daily.

Most people over the age of 60 (and a substantial minority under 60) wake up one or more times during the night to go to the bathroom. This is nightime peeing, or nocturia. Although it seems a simple problem, the lack of sleep can lead to other problems such as stress, irritability or tiredness, and so can have a significant negative impact on quality of life. There are several possible causes of nocturia. Now a group of scientists have discovered that reducing the amount of salt in one's diet can significantly reduce excessive peeing -- both during the day and when asleep.

Drug 'reverses' ageing in animal test

A drug that can reverse aspects of ageing has been successfully trialled in animals, say scientists.

They have rejuvenated old mice to restore their stamina, coat of fur and even some organ function according to BBC.

The team is planning human trials for what they hope is a treatment for old age.

A scientist said the findings were "impossible to dismiss", but that unanswered questions remained.

The approach works by flushing out retired or "senescent" cells in the body that have stopped dividing.

Dietary anti-cancer compound may work by influence on cellular genetics

Researchers have discovered one of the reasons why broccoli may be good for your health. According to Science daily

They found that sulforaphane, a dietary compound from broccoli that's known to help prevent prostate cancer, may work through its influence on long, non-coding RNAs. This is another step forward in a compelling new area of study on the underlying genetics of cancer development and progression.

The research provides more evidence for how these lncRNAs, which were once thought to be a type of "junk DNA" of no particular value or function, may instead play a critical role in triggering cells to become malignant and spread.

Daily Consumption of Tea Protects the Elderly from Cognitive Decline

Tea drinking reduces the risk of cognitive impairment in older persons by 50 per cent and as much as 86 per cent for those who are genetically at risk of Alzheimer's according to Science daily.

A cup of tea a day can keep dementia away, and this is especially so for those who are genetically predisposed to the debilitating disease, according to a recent study led by Assistant Professor Feng Lei.

The longitudinal study involving 957 Chinese seniors aged 55 years or older has found that regular consumption of tea lowers the risk of cognitive decline in the elderly by 50 per cent, while APOE e4 gene carriers who are genetically at risk of developing Alzheimer's disease may experience a reduction in cognitive impairment risk by as much as 86 per cent.
