Colliding continents have created the highest mountain ranges on our planet. Mountains like the Himalayas give us a unique opportunity to study the past and present of this ongoing process recorded in once deeply hidden rocks.
Our understanding of the complex processes and mechanisms which occur in various ecosystems is being expanded by a new field of science: biogeochemistry.
How can a properly functioning female immune system be reconciled with the events of fertilization and reproduction? Male sperm is foreign, after all, and should be destroyed by the female body. Female mammals cope with this dilemma through the cyclical influence of sex hormones on their immunity.
Identifying the genes governing longevity in yeast could lay the groundwork for studying analogous genes in humans. Will yeast prove to be an excellent model organism for gerontology research?
Rising global temperatures, mounting energy prices, increasing atmospheric pollution ... all these problems might be alleviated by better harnessing the energy from the Sun.
One could tell anecdotes about Prof. Witold Andrzej Karczewski for hours on end. As an excellent researcher, a strict boss, and an erudite humanist, he worked to promote science awareness and was devoted to public service.
You can't step into the same river twice, as they say. But it's also not easy to stand on the same riverbank twice, as rivers are constantly altering their own beds. Which, in the long run, has had a greater impact: nature or mankind?
The author Michel Schiff is quoted to have said that the "Memory of Water" and "Homeopathic Dilutions" are the two terms most capable of turning a sound person into a madman.
The latest findings indicate that the causes of infertility frequently lie on the part of the male. Fortunately, this is a condition that we know how to treat.
Do people tend to marry spouses with similar or different levels of education? In what countries is such "marital homogamy"' i.e. equal levels of education between spouses, a more frequent or rarer phenomenon? A study carried out in 22 European countries seeks to answer these questions.
A substantial majority of contemporary biological invasions are initiated intentionally or unintentionally by man. This holds true for the expansion of the harlequin ladybird.
Precise identification of the age of medieval stone buildings enables their construction to be correlated with important historical events. Using state-of-the-art dating methods, Polish researchers have solved the longstanding riddle of when the monumental constructions of medieval Poland were erected.
Through 2015, all of the growth in Poland's working-age population will occur in rural areas. After then such growth will start to wane, enabling the Polish agricultural sector to be restructured, i.e. for agricultural employment to be downsized.
10 September brought the much-awaited launch of the world's most powerful accelerator, dubbed the LHC. It may perhaps manage to find the "God particle": the long sought-after Higgs boson.
Newborn piglets offer the best model for studying mammalian gastrointestinal development, as their digestive tracts show many similarities to those of humans.
In The Jungle Book, Baloo the Bear taught Mowgli to constantly stay on his guard since the most interesting things always happen unexpectedly. That notion lies at the heart of the search for gamma ray bursts - far-off cosmic explosions of staggering magnitude.
