Mathematicians provide solution to 78 year old mystery
In previous research, it was suggested that adaptation of an animal to different factors looks like spending of one resource and that the animal dies when this resource is exhausted. In 1938, Hans Selye introduced "adaptation energy" and found strong experimental arguments in favour of this hypothesis. However, this term has caused much debate because, as it cannot be measured as a physical quantity, adaptation energy is not strictly energy.

Adherence to nutrition recommendations, use of supplements essential for vegans
Latest Science News -- ScienceDaily - Hace 1 día
Vegans adhere to nutrition recommendations in varying degrees, according to a new Finnish study. Some vegans who participated in a new study followed a balanced diet, while others had dietary deficiencies. Typical deficiencies were an unbalanced use of protein sources, a low intake of berries, fruits and nuts, as well as failure to use nutrient fortified food products. The majority, however, used vitamin B12 and D supplements and calcium-fortified drinks as recommended.

Making the most out of biological observations data
Creating and maintaining a biodiversity data collection has been a much-needed worldwide exercise for years, yet there is no single standard on how to do this. This has led to a myriad of datasets often incompatible with each other.

Five ways nanotechnology is securing your future
The past 70 years have seen the way we live and work transformed by two tiny inventions. The electronic transistor and the microchip are what make all modern electronics possible, and since their development in the 1940s they've been getting smaller. Today, one chip can contain as many as 5 billion transistors. If cars had followed the same development pathway, we would now be able to drive them at 300,000mph and they would cost just £3 each.

During unfavourable conditions the cytoplasm can solidify and protect the cell from death
Normally, cells are highly active and dynamic: in their liquid interior, called the cytoplasm, countless metabolic processes occur in parallel, proteins and particles jiggle around wildly. If, however, those cells do not get enough nutrients, their energy level drops. This leads to a marked decrease of the cytoplasmic pH – the cells acidify. In response, cells enter into a kind of standby mode, which enables them to survive. A team of researchers from Dresden, Germany, have found out that the cytoplasm of these seemingly dead cells changes its consistency from liquid to solid. There... más »
Migratory birds disperse seeds long distances
Some species of plants are capable of colonising new habitats thanks to birds that transport their seeds in their plumage or digestive tract. Until recently, it was known that birds could do this over short distances, but a new study shows that they are also capable of dispersing them over more than 300 kilometres. For researchers, this function could be key in the face of climate change, allowing the survival of many species.
