A new type of wheat bred with a gene that removes sodium from water can outgrow conventional strains by up to 25% in salty soils, Australian scientists have found. The breakthrough by a team from CSIRO…
It’s time for a change in the way we categorise life on Earth.
ஆ ன ந் த ம் / a n a n d h a m
It might surprise you to learn that the idea of a “species” is one of the more ambiguous concepts in science. Originally, “species” (meaning “kind” or “sort” in Latin) was used to refer to organisms that…
Rejoice: rumours of male extinction may be out of line.
StuartOlver
There’s something degenerate in every male (no, seriously). We members of the facial-hair-bearing sex carry, among the 23 pairs of chromosomes in every one of our cells, an odd pair of sex-chromosomes…
The colony of King Penguins on Macquarie Island was almost extinct by 1930.

Eighty years after slipping to the brink of extinction, a colony of King Penguins at Macquarie Island in the Southern Ocean has rebounded and is flourishing through conservation efforts, Australian researchers…
Genetic variants that contribute to the risk of schizophrenia are present in everyone.

A quarter of the risk for developing schizophrenia can be traced to genetic variations that are common in the general population, a study by Queensland researchers has found. A new method of genetic analysis…
The proportion of people with desirable physical traits could rapidly accelerate over a few generations with the aid of a diet that tweaks particular genes, a study suggests. Research by a team at Sydney’s…
Researchers have taken important steps in conserving endangered cats.

Looking at embryonic cells allows researchers to understand many of the fundamental questions about how an animal’s genes are structured and the role they play in developing the adult animal. This information…
When we think of the last 50,000 years of prehistory, particularly the “Ice Age”, extinct species such as the woolly mammoth and woolly rhinoceros often spring to mind. Did humans bring about the extinction…
Motherhood has made women’s immune systems stronger.

Research published in this month’s BioEssays confirms something many of us have always known: women have stronger immune systems than men. We fight off infections more readily, are less likely to develop…
Stem cell experiments on mice have been shown to correct a liver disorder, but would it work on humans?

For the first time, scientists have been able to fix a genetic liver defect in tests on mice using stem cells created from human skin, marking a potential major breakthrough in the repair of genetic disorders…
It’s clear that some people are just more predisposed to getting melanoma with the same level sun exposure than others.

An international study published today in Nature Genetics, has discovered two genetic variants that increase the risk of melanoma. Melanoma is not the most common type of skin cancer but it is one of the…
