Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Gene activity and transcript patterns visualized for the first time in thousands of single cells
Biologists of the University of Zurich have developed a method to visualize the activity of genes in single cells. The method is so efficient that, for the first time, a thousand genes can be studied in parallel ...
Scientists smash barrier to growing organs from stem cells
(Phys.org) —Scientists at the University of Virginia School of Medicine have overcome one of the greatest challenges in biology and taken a major step toward being able to grow whole organs and tissues ...
Researchers discover ancient virus DNA remnants necessary for pluripotency in humans
Tarantula toxin is used to report on electrical activity in live cells
Crucial experiments to develop a novel probe of cellular electrical activity were conducted in the Neurobiology course at the Marine Biological Laboratory (MBL) in 2013. Today, that optical probe, which combines ...
Scientists replicate key evolutionary step in life on earth
(PhysOrg.com) -- More than 500 million years ago, single-celled organisms on Earth's surface began forming multi-cellular clusters that ultimately became plants and animals.
Evolution of life's operating system revealed in detail
The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
Researchers create embryonic stem cells without embryo
(Phys.org) —Since the discovery of human embryonic stem cells, scientists have had high hopes for their use in treating a wider variety of diseases because they are pluripotent, which means they are capable ...
Team visualized DNA double-strand break process for the first time
Scientists from the Spanish National Cancer Research Centre (CNIO), led by Guillermo Montoya, have developed a method for producing biological crystals that has allowed scientists to observe —for the first ...
The ultimate biofilament: Hagfish slime
Scientists' new analysis of plant proteins advances our understanding of photosynthesis
A world without plants would be a world without oxygen, uninhabitable for us and for many creatures. We know plants release oxygen by absorbing carbon dioxide and breaking down water using sunlight through ...
Viruses hijack deep-sea bacteria at hydrothermal vents
More than a mile beneath the ocean's surface, as dark clouds of mineral-rich water billow from seafloor hot springs called hydrothermal vents, unseen armies of viruses and bacteria wage war.
Origins of life? Discovery could help explain how first organisms emerged on Earth
(Phys.org) —A structural biologist at the Florida State University College of Medicine has made discoveries that could lead scientists a step closer to understanding how life first emerged on Earth billions ...
Dispersal patterns key to invasive species' success
In 1859 an Australian farmer named Thomas Austin released 24 grey rabbits from Europe into the wild because it "could do little harm and might provide a touch of home, in addition to a spot of hunting."
