New Eco Friendly De-Inking Process Developed.
A new technology utilising enzymes (biological molecules) has been shown to remove ink from recycled paper. A research project conducted by the University of Malaysia Sarawak reported the use of a crude enzyme preparation for the enzymatic de-inking of mixed office paper. Traditional de-inking methods have involved the use of large quantities of chemicals, causing pollution to the environment. The enzyme material was prepared by growing endoglucanase (enzyme use for the enzymatic treatment) producing Bacillus licheniformis BL-P7 in a liquid culture media containing sago pith waste and rice husk. Furthermore, the process proved to be more effective for the removal of larger ink particles. Also, properties such as brightness, air permeability, tensile, and tear were enhanced in the preparation of the recycled mixed office paper.

Organic Wine Leaves Only Half the Eco Footprint of Non-Organic!
Italian environmental scientists from the University of Siena, measured the resources needed to produce wine at two farms in Tuscany. Both were utilizing Sangiovese grapes but one was totally organic and the other was not. The organic farm used natural fertilisers and most of the work was done by hand, while the other farm used conventional methods of production. A bottle from the organic farm had an eco-footprint of 7.17 square metres, half that of the non-organic wine with a footprint of 13.98 square metres.

Low Sperm Count Link to Soy also includes Nuts, Wines and Beers
The high levels of oestrogen like chemicals in soya beans have also been found in beers, wines and nuts. Gunter Kuhnle of the MRC Dunn Human Nutrition Unit in Cambridge, UK tested foods and beverages using mass spectrometry. Previous testing had focused on lignans but ignored isoflavones and this expanded search has found phytoestrogens in many more foods and drinks. Studies into the effects of phytoestrogens have produced a mixture of results, with some showing compounds that protect against cancer, menopausal symptoms and heart diseases, whilst others have been linked to increased risk of breast cancer and male infertility.

A-Beta Protein Alzheimer Disease Clues
Amyloid-beta the thinking brain’s protein has been shown to be intrinsically involved in increased neuron activity. A study into people with severe brain injuries resulted in steadily rising levels of A-beta protein as their brain activity increased through recovery. A-beta, as the protein is sometimes called, is best known for causing plaques in the brains of people with Alzheimer’s disease. It is a normal component of the brain, but scientists don’t know what it does. Traumatic brain injuries increase the risk for Alzheimer’s disease. Researchers from Milan, Italy and Washington University in St. Louis, USA used advance brain testing techniques to ascertain if brain injuries cause a spike in amyloid-beta levels that could lead to plaque formation, a team of researchers from Milan, Italy, sampled fluid from the brains of 18 comatose patients.
What the researchers found was exactly the opposite of what they expected, says David L. Brody, a neurologist at Washington University who led the study with Sandra Magnoni of the Ospedale Maggiore in Milan. Instead of seeing a spike of A-beta soon after brain injury from falls, car accidents, assaults or hemorrhages, levels of the protein started low and rose as the patients improved, the team reports in the Aug. 29 Science.
Farm Kids Avoid Asthma & Allergies
Pre-natal exposure to farm animals and plants helps protect children from asthma, allergies and eczema. Researchers from the Centre for Public Health Research discovered farmers’ children had a lower incidence of allergic diseases than children not exposed to animals, grain and hay products. The findings have been published in the European Respiratory Journal. Associate Professor Jeroen Douwes says it is the first study to show a direct link between exposures in utero and a significant reduction in asthma symptoms, hay fever and eczema.

So you’ve had a baby, what happened to sex?
By Jan Roberts
If you’ve just had a baby you might be wondering whatever happened to sex. Rest assured that many women are relatively sexually uninterested after childbirth and during breastfeeding. In fact it’s quite normal and is Nature’s way of spacing out your children in the most effective way. Studies show a wide variation of sexual behaviour among women after childbirth. Every woman is different and no response is ‘normal’ or better than another.
In fact, in some cultures, post-childbirth sexual abstinence is compulsory, and it is considered ‘bad form’ for children to be born very close together. For example, in Sierra Leone sexual abstinence lasts for a full year, in some Pacific Island cultures it lasts for two. Although some women experience a highly charged vitality, even in the first few days after birth, and find their sexual energy also heightened, there are many reasons why you may be less sexually motivated than before.
The factors involved include hormonal changes, your new role as a mother (and your joint role as parents), your levels of energy (or fatigue), your emotional state, physical problems resulting from childbirth, your new body image, your possible fear of another pregnancy and your partner’s attitude to it all. As well as letting your body and libido recover at their own rate it’s important to understand why you feel the way you do.
While you’re breastfeeding, raised levels of prolactin are produced by your pituitary gland. This is the hormone that controls lactation and also has a sedative effect. Another result of increased prolactin production is that ovulation is delayed. In the absence of an ovulation cycle, normal ovarian hormones such as oestrogen won’t peak once a month to trigger the release of an egg, and this affects your sexual motivation which is highest at ovulation.
Oxytocin, the hormone responsible for the ‘let-down’ reflex, is the same hormone that is released at orgasm, and its release during breastfeeding may make you less likely to look for sexual satisfaction with your partner. Part of the delight you take in your new baby will be sensual. The skin-to-skin contact, so vital for him, is also exquisitely pleasurable for you. This, coupled with the intense feelings of love you feel, will probably mean that you are emotionally and physically focused on your child, and on your breastfeeding relationship.
It’s a common joke that birth control in the postnatal period is mostly achieved through ‘baby interruptus’. The best way round this is to keep your baby in (or at least near) the bed with you. In this way he can still sense that you are close, and will stay peacefully asleep. Even if he does wake, you can tend to him without too much disturbance. This arrangement also overcomes the problem of sleep deprivation. A breastfed baby will want to feed more often, so, in order that this doesn’t affect your sleep too adversely, keep your baby in the family bed, or at least within reach, so you can satisfy his hunger without getting out of bed.
However well you manage your night time feeds, you may still find at the end of the day, or at any time when you can relax, that all you want to do is sleep, and that sex is the furthest thing from your mind. Obviously the best plan is to sleep when your baby does, but this may not leave much room (or desire) for sexual activity. If you and your partner feel like ships passing in the night, make ‘appointments’ to at least meet and talk, and arrange to set aside special times to get together. These times may not necessarily lead to sex, but they will set the right intent for a time when libido is restored and you feel ready to resume regular sexual activity.
