Ricochet, you take your aim
Fire away, fire away

Avoiding meat and dairy is single biggest
way to reduce your impact on Earth
Avoiding meat and dairy products is the single biggest way to reduce your environmental impact on the planet, according to the scientists behind the most comprehensive analysis to date of the damage farming does to the planet.
The new research, published in the journal Science, shows that without meat and dairy consumption, global farmland use could be reduced by more than 75% – an area equivalent to the US, China, European Union and Australia combined – and still feed the world. Loss of wild areas to cattle farming is the leading cause of the current mass extinction of wildlife.
The new analysis shows that while meat and dairy products provide just 18% of calories and 37% of protein, they use the vast majority – 83% – of farmland and produce 60% of farming greenhouse gas emissions. Other recent research shows 86% of all land mammals are now livestock or humans. The scientists also found that even the lowest impact by meat and dairy products may cause much more environmental harm than the least sustainable vegetable and cereal growing.

Natural tooth repair method, using Alzheimer's
drug, could revolutionise dental treatments
A new method of stimulating the renewal of living stem cells in tooth pulp using an Alzheimer’s drug has been discovered by a team of researchers at King’s College London.
Following trauma or an infection, the inner, soft pulp of a tooth can become exposed and infected. In order to protect the tooth from infection, a thin band of dentine is naturally produced and this seals the tooth pulp, but it is insufficient to effectively repair large cavities. Currently dentists use manmade cements or fillings, such as calcium and silicon-based products, to treat these larger cavities and fill holes in teeth. This cement remains in the tooth and fails to disintegrate, meaning that the normal mineral level of the tooth is never completely restored.
However, in a paper published today in Scientific Reports, scientists from the Dental Institute at King’s College London have proven a way to stimulate the stem cells contained in the pulp of the tooth and generate new dentine in large cavities, potentially reducing the need for fillings or cements.
The novel biological approach could see teeth use their natural ability to repair large cavities rather than using cements or fillings.
Significantly, one of the small molecules used by the team to stimulate the renewal of the stem cells included Tideglusib, which has previously been used in clinical trials to treat neurological disorders including Alzheimer’s disease.
Using biodegradable collagen sponges to deliver the treatment, the team applied low doses of small molecule glycogen synthase kinase (GSK-3) inhibitors to the tooth. They found that the sponge degraded over time and that new dentine replaced it, leading to complete, natural repair. Collagen sponges are commercially-available and clinicallyapproved, again adding to the potential of the treatment’s swift pick-up and use in dental clinics.

Rare animals vital for ecosystem life support
Rare animal species are vital to maintaining tropical ecosystems and could cause a chain reaction of disastrous biodiversity loss if they go extinct, a study warns.
Animals that are considered rare – because they occupy a niche environment or there are few of them – are more likely than common animals to perform specialised and often irreplaceable roles in their environments, the study found. This is especially true for highly biodiverse environments, such as the tropics, the researchers say. “Losing rare species today may mean losing much more complex processes in the long term,” says lead author Rafael Leitão, a biologist at the National Institute of Amazonian Research in Manaus, Brazil.
The study notes that rare animals perform essential “ecosystem services” such as dispersing seeds, filtering water and controlling other animal populations and invasive species. “There is no way to know exactly how, in future, an ecosystem 11 with the loss of those rare species, but chain effects are common, meaning that the loss of some functions can lead to other losses, making the whole environment crumble,” says Leitão.

Can there be a world without antibiotics?
Medical experts around the globe are worried that more and more viruses and bacteria are becoming resistant to today’s medicine. They are afraid that in a few generations antibiotics may become useless. Scientists have already discovered bacteria that do not react if treated with antibiotics. As a result medical treatment will become more expensive as new drugs have to be developed.
Doctors and other health experts criticize the fact that antibiotics are being used in a wrong way. They are often prescribed in cases in which they do not work. In some areas, especially Third World countries and densely populated areas in India, Pakistan or Bangladesh doctors have already run out of antibiotics. Prescribing wrong antibiotics or taking them for too short a time will not kill off bacteria. Some doctors prescribe antibiotics for the common flu, making it ineffective for later illnesses. The World Health Organization claims that many infectious diseases are becoming untreatable and cannot be controlled. Many patients who become resistant to drugs even die.
Another problem is that farmers in the United States and Europe are adding antibiotics to feed cattle and other animals, in order to make them grow faster and produce more meat. Also, through increased global travel, bacteria are spreading faster than ever before.
Since Alexander Fleming discovered penicillin in the early 20th century antibiotics have saved hundreds of millions of lives. Many operations cannot be carried out if we are unable to treat infections. The transplantation of organs can become very risky if patients do not get medication to strengthen their immune system. Routine operations like removing an appendix or replacing a bad hip could become fatal. Childbirth may once again threaten a woman’s life and raise child mortality. Even illnesses like pneumonia, which today can be treated effectively with antibiotics, might once again turn into a mass killer. Antibiotics have made infections like tuberculosis treatable. Cancer treatment would be unthinkable without the proper treatment of the immune system to accompany it.
Health experts call for increased action to fight off diseases. Most common is the call to improve hospital hygiene, where infectious diseases start out. Especially in Third World countries, bacteria spread through dirty water and the sewage system. Even making people aware of washing their hands more often can stop the spread of infectious diseases.
