An article by Dr. Xavier Trepat, senior researcher of the Cellular and respiratory biomechanics group at the University of Barcelona, Spain, contributes for the first time an experimental answer to the question of how cells ...
Over the last decade, powerful new microscopes have dramatically sharpened biologists' focus on the molecules that animate and propel life. Now, a new imaging platform developed by Eric Betzig and colleagues at the Howard ...
After two decades of examining a microscopic algae-eater that lives in a lake in Norway, scientists on Thursday declared it to be one of the world's oldest living organisms and man's remotest relative.
Skates have primitive colons. This may not sound like a big deal, but it is. The discovery could change scientific understanding of evolution, of how animals emerged from water to live on land.
(PhysOrg.com) -- Microfossils found in Australia show that more than 3.4 billion years ago, bacteria thrived on an Earth that had no oxygen, a finding that boosts hopes life has existed on Mars, a study published Sunday says.
(PhysOrg.com) -- Scientists at Oxford University have shown for the first time that molecular cages made from DNA can enter and survive inside living cells.
A team from the Spanish National Cancer Research Centre (CNIO) has become the first to make adult cells from a living organism retreat in their evolutionary development to recover the characteristics of embryonic stem cells.
University of Houston researchers have devised a new method for extracting molecules from live cells without disrupting cell development, work that could provide new avenues for the diagnosis of cancer and other diseases.
