New insights in survival strategies of bacteria
Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial ...
Proteins can be easily and sensitively detected by their scattered light
In future, some diseases might be diagnosed earlier and treated more effectively. Researchers at the Max Planck Institute for the Science of Light in Erlangen have developed an optical method that makes individual ...
X-rays unlock a protein's SWEET side
Sugar is a vital source of energy for both plants and animals alike.
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
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 ...
Wiping the slate clean: Erasing cellular memory and resetting human stem cells
Babraham Institute scientists, in collaboration with colleagues at the Cambridge Stem Cell Institute and the European Bioinformatics Institute, have published findings today in the journal Cell giving hope that researchers will b ...
Team makes scientific history with new cellular connection
Researchers led by Dr. Helen McNeill at the Lunenfeld-Tanenbaum Research Institute have revealed an exciting and unusual biochemical connection. Their discovery has implications for diseases linked to mitochondria, ...
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."
