A world leader in medical implants calls for a rethink in our approach to building medical implants.

The ancient gray wolves of Alaska became extinct some 12,000 years ago, and the wolves in Alaska today are not their descendents but a different subspecies, an international team of scientists reports in the July 3 print edition of the journal Current Biology.

Independent research, involving over 3 million Italians, conducted by Henley Management College and the University of Milan has concluded that the prescription costs for men over the age of 65 is significantly higher than it is for women. The study is published in the July 4th issue of the online, open-access journal PLoS ONE.

Insects make up more than half of the known animal species on our planet and they can be found in all kinds of habitat and feed on all kinds of nutrients. They can even be used in evidence in court cases. So we are talking about forensic entomology.

From the deepest seafloor to the highest mountain, from the hottest region to the cold Antarctic plateau, environments labelled as extreme are numerous on Earth and they present a wide variety of features and characteristics. Investigating life processes in extreme environments not only can provide hints on how life first appeared and survived on Earth (as early earth was an extreme environment) but it can also give indication for the search for life on other planets.

A gene that is strongly associated with a risk of developing childhood onset asthma was identified by an international team of scientists, whose findings are published today in the journal Nature.

Researchers from the Stem Cell Transplant Program and the Amyloid Treatment and Research Program at Boston University Medical Center (BUMC) have found that tandem cycles of high-dose chemotherapy and blood stem cell transplantation can help treat patients with immunoglobulin-light chain (AL) Amyloidosis who did not respond to initial treatment with this method. These findings were published on-line in the June 25th issue of Bone Marrow Transplantation.

For the first time, scientists have used satellite images to demonstrate a link between rapid city growth and rainfall patterns, as well as to assess compliance with an international treaty to protect wetlands. The results have been published in two studies co-authored by Karen Seto, assistant professor of geological and environmental sciences and a fellow at the Woods Institute for the Environment at Stanford University.

Researchers in Slovakia have been able to derive mesenchymal stem cells from human adipose, or fat, tissue and engineer them into “suicide genes” that seek out and destroy tumors like tiny homing missiles. This gene therapy approach is a novel way to attack small tumor metastases that evade current detection techniques and treatments, the researchers conclude in the July 1 issue of Cancer Research, a journal of the American Association for Cancer Research.

Forget expensive moisturisers and cosmetic surgery, a compound found in the humble elderberry could give a natural boost to skin.

In some regions of Central Europe, salad dressing is made preferably with pumpkin seed oil, which has a strong characteristic nutty flavor and striking color properties. Indeed, in a bottle it appears red, but it looks green in a salad dressing or mixed with yoghurt.
