Researchers find animals killed by anthrax leave behind enticing grasses for herbivores, allowing disease to spread
What happens when good genes get lost?
Scientifically speaking, there is no bad DNA, though we like to blame it for unruly hair, klutziness or poor gardening skills. There is, however, junk DNA.
At dusk and dawn: Scientists pinpoint biological clock's synchronicity
Scientists have uncovered how pacemaker neurons are synchronized at dusk and dawn in order to maintain the proper functioning of their biological clocks. Their findings, which appear in the journal PLOS Biology, enhance our un ...
Breakthrough study discovers six changing faces of 'global killer' bacteria
Every ten seconds a human being dies from Streptococcus pneumoniae infection, also known as pneumococcus, making it a leading global killer.
Research shows viral DNA infects cells by changing from solid to fluid-like state
Many double-stranded DNA viruses infect cells by ejecting their genetic information into a host cell. But how does the usually rigid DNA packaged inside a virus' shell flow from the virus to the cell?
Green light for clever algae
Phytoplankton not only constitutes the foundation of the food chain in the oceans, it also fixes carbon through photosynthesis and generates oxygen with the help of solar energy. A considerable part of phytoplankton ...
Unlocking long-hidden mechanisms of plant cell division
Along with copying and splitting DNA during division, cells must have a way to break safely into two viable daughter cells, a process called cytokinesis. But the molecular basis of how plant cells accomplish ...
Scientists identify key factor that maintains stem cell identity
A protein implicated in several cancers appears to play a pivotal role in keeping stem cells in an immature "pluripotent" state, according to a new study by NYU Langone Medical Center scientists. The study ...
New technique reveals a role for histones in cell division
(Phys.org) —Proteins known as histones give structure to DNA, which coils around them like string on spools. But as is so often the case in biology, it turns out there is more to these structures than meets ...
Insect genomes' analysis challenges universality of essential cell division proteins
Cell division, the process that ensures equal transmission of genetic information to daughter cells, has been fundamentally conserved for over a billion years of evolution. Considering its ubiquity and essentiality, it is ...
Engineers combine mechanics with biology to make key discovery about communication between cells
When the body forms new tissues during the healing process, cells must be able to communicate with each other. For years, scientists believed this communication happened primarily through chemical signaling. Now researchers ...
Genetic switch regulates a plant's internal clock based on temperature
Scientists have discovered a key molecular cog in a plant's biological clock – one that modulates the speed of circadian (daily) rhythms based on temperature.
Geometry, programmed death might have enabled evolution of multicellularity
Geometry and programmed cell death may have helped along the evolution of multicellular life, according to new research led by SFI Omidyar Fellow Eric Libby.
How the signal from light triggers biological action in bacteria
Sunlight is the basis for all life on Earth so it should come as no surprise that many organisms have developed complex systems for detecting the quality and quantity of light in their environment. Plants, ...
