However, the research published today suggests that caching a fallen seed is just the beginning of a seed-stealing saga that carries each over long distances. Further clinical testing could lead to an effective, gentler treatment for the skin condition. Researchers from Leeds Metropolitan University tested the effect of thyme, marigold and myrrh tinctures on Propionibacterium acnes — the bacterium that causes acne by infecting skin pores and forming spots, which range from white heads through to puss-filled cysts.
The group found that while all the preparations were able to kill the bacterium after five minutes exposure, thyme was the most effective of the three. Dr Margarita Gomez-Escalada who is leading the research project explained how tinctures are made from plants and herbs.
This process draws out the active compounds from the plant. The researchers used a standard in vitro model that is used to test the effect of different substances applied to the skin. The effects of the tinctures were measured against an alcohol control — proving their antibacterial action was not simply due to the sterilizing effect of the alcohol they are prepared in.
These initial findings pave the way for more research into the use of tinctures as a treatment for acne. A herbal treatment for acne would be very welcome news - particularly for acne sufferers who experience skin sensitivity. Herbal preparations are less harsh on the skin due to their anti-inflammatory properties while our results suggest they can be just as, if not more, effective than chemical treatments.
There may be as few as 25 of these trees in the world, yet eight of them are at Henry Cowell Redwood State Park in Northern California. These trees are not just pale: A genetic mutation has prevented them from producing chlorophyll, and the result is that they're entirely unable to photosynthesize.

So how can a plant not only survive, but grow, without the ability to produce its food? The only reason that albino redwoods survive at all is that they are connected at the root to a parent tree from which they will suck energy for their entire lives," Amy Standen says. In the case of the redwoods, this arrangement can last a century, or more - and no one knows why. But this isn't just an intriguing insight into photosynthesis. The albino redwoods have a lot to tell us about the process of evolution.

Park ranger Dave Kuty explains that redwoods are hexaploid, meaning they have six sets of chromosomes, rather than the two sets of chromosomes that humans have.
There are more genetic combinations possible," as Amy puts it. Redwoods are thought to be the most adaptable tree on earth by being able to change their genes so readily.
If it works, that tree might set the course for the generations of the future.

They can develop resistance to fungi. They can develop resistance to viruses. DNA determines the characteristics of a living organism. With the exception of identical twins, each person's DNA is unique. The order of these letters makes up an organism's genetic code. An organism's genome is one copy of all of their DNA. With the exception of identical twins, no two people's genomes are the same.
Some characteristics are controlled by a single gene, such as fur in animals and red-green colour blindness in humans. Each gene might have different forms, and these are called alleles. The diagram shows the relationship between the cell, its nucleus, chromosomes in the nucleus, and genes.Ecological Relationships
Chromosomes are made from genes which are made from the DNA double helix Chromosomes are found in the nucleus of a body cell in pairs. One chromosome of each pair is inherited from the mother and the other one is inherited from the father. The chromosome in each pair carries the same gene in the same location.
These genes could be the same, or different versions: Alleles are different versions of the same gene.

For example, the gene for eye colour has an allele for blue eye colour and an allele for brown eye colour. For any gene, a person may have the same two alleles, known as homozygous or two different ones, known as heterozygous. A dominant allele is always expressed, even if one copy is present.
