Millions of nuts, bolts, pieces of metal and carbon, and whole spacecraft from thousands of missions and launches form an orbiting garbage dump spinning around the Earth at speeds up to 22,000 mph.

After the recent collision between a Russian and U.S. satellite, concern for the growing hazard of space junk is becoming even more acute within the international space community. In recent months, NASA and the European Space Agency have both diverted resources into monitoring space debris and researching ways of mitigating and—some day—removing it.

Gay, the Asian elephant, has been suffering from very sore feet recently.  For the past several months, keepers at the Paignton Zoo Environmental Park have been keeping a close eye on the 40-year-old elephant.  Although she gets regular pedicures and antibiotic foot baths, Gay has been suffering from painful abscesses in both her front feet.

Scientists out of the University of Utah have created a new substance, heralded as a molecular condom, which blocks HIV from entering the vaginal tissue. HIV infection is a huge problem in Africa, and other impoverished areas, mostly because of a taboo or unavailability of condoms. The gel is meant to give woman a way to protect themselves from infection without any approval of their partner.

“This is important – particularly in resource-poor areas of the world like sub-Sahara Africa and south Asia where, in some age groups, as many as 60 percent of women already are infected with HIV. In these places, women often are not empowered to force their partners to wear a condom.” - Patrick Kiser, an associate professor of bioengineering at the University of Utah

Editor’s Note: This is a guest post from David Hone, Climate Change Adviser for Shell.

I have been in Sao Paulo this week at Sustentavel 2009, perhaps the premiere Sustainable Development event in Brazil, if not all of South America. At the opening I represented the World Business Council for Sustainable Development and then on the first day of presentations I participated in the main climate change panel session.

What is clear is that there is a passion in Brazil for sustainability – from the huge issues they face in the Amazon region to the road congestion in Sao Paulo. Talking with delegates at Sustentavel, it is also clear that the country faces an interesting future in terms of greenhouse gas emissions.

Yu-Chan, an endangered loggerhead sea turtle, is one very lucky turtle.  Found entangled in fishing nets in Japan in 2008, the 20-year-old loggerhead had also been attacked by a shark.   Covered in bite wounds, she lost half of her forelimb and part of another due to her injuries.

Before I get into this important topic, please read my article on cancer dedicated to someone special to me, each view constitutes a larger donation to cancer research. http://planetsave.com/blog/2009/07/27/help-me-fight-cancer/

Problem

Almost one half of non-human primates are at risk of extinction, and none more so than gorillas. Gorillas are disappearing at an alarming rate, mostly a victim of their surroundings. Political unrest, wars, poachers, miners, and loggers all converging in a perfect storm of brutality and human depravity, killing one of our closest living relatives. Gorilla’s DNA is 98-99% an exact match for human DNA, just barely trailing our closest living relatives (genus Pan, chimpanzees and bonobos). Unfortunately for the gorillas, they occupy a region rich in tin, diamonds, gold and coltan (a rare mineral used to create capacitors for cellphones, games consoles and laptops).

Scanning electron micrograph of Escherichia coli

Using two different model organisms–the E. coli bacterium and the single-celled yeast–scientist have begun unraveling a puzzling behavior of many micro-organisms: the ability to “predict” a change in environmental conditions.

It has been assumed for most of the history of micro-biological science that such micro-organisms are purely “reflexive”; they simply respond and adapt to external stimuli (such as exposure to chemicals, heat stress, or drugs). But research over he past 2 years by two different scientific teams (a Princeton team lead by Saeed Tavazoie, and, a team from the Weizmann Institute in Israel) is shaking up present understanding and over-turning basic assumptions.

Move over Nature…the famed strength of a spider’s web silk now has some competition. Bio-mimicry and bio-materials–both emerging new sciences that seek to utilize and/or reproduce or modify natural biological materials and properties for commercial usage–has been seeing an explosion of research and experimentation of late. Recent bio-materials experiments with spider dragline silk (taken from an Araneus spider’s silk glands) have resulted in a bio-mimicked new material that is stronger than its natural version.

To make this new material, the scientists had to “infiltrate” the inner protein structure of the spider’s dragline, silk threads with a metal ion of zinc (Zn 2+). These experiments built on earlier analyses of the mandibles of leaf-cutter ants, locusts, and marine polychaetes (a type of large sea worm) that showed a strong relationship between accumulated Zinc, Aluminum and Titanium levels in these materials and their high tensile and hardness properties.  Previous attempts to incorporate such metals synthetically had proven to be too great a technological challenge.

Two Kenyan students have invented a device that allows bicycle riders to charge their phones as they pedal.

Deemed a “dynamo-powered smart charger”, the device should make it more economical for the 17.5 million Kenyans who use mobile phones to charge them. Even more impressive, the environmentally-friendly phone charger was originally built from scraps retrieved from a junkyard.

In a meeting with environment and energy ministers from other European countries yesterday, Sweden’s Minister of Environment, Andreas Carlgren, said that global economic problems should in no way slow movement to address climate change. Other leading European ministers agreed.

Economic problems today are in many ways a result of environmental missteps in the past. If we want a healthy economy in the future, we have to take the environment into account more than we have. The Swedish Minister of the Environment agrees and says that there should be no hesitation to combat climate change due to the current economic situation. Read the rest of this entry »
