Researchers found that warmer summers have allowed the Brown Argus butterfly to complete its life cycle by eating wild Geranium plants. Because the Geraniums are widespread in the British countryside, this change in diet has allowed the butterfly to expand its range in Britain at a surprisingly rapid rate. Over the past 20 years, the Brown Argus has spread northwards by around 79 kilometres and has become common in the countryside in much of southern England.

New research includes an analysis of extraordinary episodes such as the violent storm that hit the Catalan coast on 26 December 2008, which caused the disappearance of around 80% of the population of sea urchins in the archipelago of the Medes and the Montgrí coast. Thu, 24 May 2012 09:22:22 EDT http://www.sciencedaily.com/releases/2012/05/120524092228.htm http://www.sciencedaily.com/releases/2012/05/120524092222.htm The human olfactory bulb – a structure in the brain that processes sensory input from the nose – differs from that of other mammals in that no new neurons are formed in this area after birth. The discovery is based on the age-determination of the cells using the carbon-14 method, and might explain why the human sense of smell is normally much worse than that of other animals. Thu, 24 May 2012 09:22:22 EDT http://www.sciencedaily.com/releases/2012/05/120524092222.htm http://www.sciencedaily.com/releases/2012/05/120524092046.htm Stem cells are essential building blocks for all organisms, from plants to humans. They can divide and renew themselves throughout life, differentiating into the specialized tissues needed during development, as well as cells necessary to repair adult tissue. Therefore, they can be considered immortal, in that they recreate themselves and regenerate tissues throughout a person’s lifetime, but that doesn’t mean they don’t age. They do, gradually losing their ability to effectively maintain tissues and organs. Now, researchers have uncovered a series of biological events that implicate the stem cells' surroundings, known as their "niche," as the culprit in loss of stem cells due to aging. This research has implications for treatment of age-related diseases and for the effectiveness of regenerative medicine.

Researchers say individuals with variations in certain "obesity genes" tend to eat more meals and snacks, consume more calories per day and choose the same high fat, sugary foods. Wed, 23 May 2012 11:48:48 EDT http://www.sciencedaily.com/releases/2012/05/120523114847.htm http://www.sciencedaily.com/releases/2012/05/120523114730.htm Empoasca is not a typical pest of wild tobacco. When this plant grows in its natural habitats in North America, however, it is attacked by tobacco hornworm larvae. This specialist insect is resistant to the toxic nicotine, which the plant produces as a defense against its enemies. When researchers used particular transgenic plants in field experiments, they noticed that these plants were heavily infested with Empoasca leafhoppers. In the particular transgenic plants used in this study, a certain gene had been switched off which is essential for the production of jasmonic acid. Due to their inability to produce jasmonates, the plants could not activate their defenses against herbivores, because their hormonal signalling cascades were interrupted. The result of this deficiency was visible and had been expected: a heavy infestation by tobacco hornworm larvae. The occurrence of leafhoppers, however, was a surprise, because these insects are not a part of the plant’s normal herbivore community. The scientists speculated that these insects which are common pests of agricultural crops may have been able to evaluate the defensive potential of their host plants before the plants could activate the production of their defenses.

However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife.

A new device however, can reveal much the same information as a traditional blood test in real-time, simply by shining a light through the skin. This portable optical instrument is able to provide high-resolution images of blood coursing through veins without the need for harsh fluorescent dyes.

Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response. Researchers have now elucidated the structure of such a needle at atomic resolution. Their findings might contribute to drug tailoring and the development of strategies which specifically prevent the infection process.
