Bioengineers invent 'light tube array,' 'bioscilloscope' to test, debug genetic circuits
(Phys.org) —In a significant advance for the growing field of synthetic biology, Rice University bioengineers have created a toolkit of genes and hardware that uses colored lights and engineered bacteria ...
Secrets to 'extreme adaptation' found in Burmese python genome
The Burmese python's ability to ramp up its metabolism and enlarge its organs to swallow and digest prey whole can be traced to unusually rapid evolution and specialized adaptations of its genes and the way ...
Study suggests why, in some species, mere presence of males shortens females' lifespan
Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.
Siberian hamsters show what helps make seasonal clocks tick
Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping ...
Criticality in morphogenesis
A decade of improvements on the reference green alga genome
The high-quality genome sequence of the tiny single-celled alga Chlamydomonas reinhardtii has proved useful for researchers studying photosynthesis and cell motility.
Timing is not only ticking: Researchers discover that a Doppler effect influences segmentation
Many animals exhibit segmental patterns that manifest themselves during development. One classical example is the sequential and rhythmic formation the segmental precursors of the backbone, a process that ...
'Tom Sawyer' regulatory protein initiates gene transcription in a hit-and-run mechanism
A team of genome scientists has identified a "hit-and-run" mechanism that allows regulatory proteins in the nucleus to adopt a "Tom Sawyer" behavior when it comes to the work of initiating gene activation.
Long non-coding RNAs can encode proteins after all
Case Western Reserve School of Medicine scientists have made an extraordinary double discovery. First, they have identified thousands of novel long non-coding ribonucleic acid (lncRNA) transcripts. Second, they have learned ...
The genes tell crows to choose partners that look alike
Crows like to select mates that look alike. In a large-scale genomic study, published in Science today, a team of researchers led by Uppsala University found that this behaviour might be rooted in their ...
Cricket fertility found to improve with age
UWA scientists researching the seminal fluid of field crickets (teleogryllus oceanicus) are a step closer to knowing why the insect's competitive fertilisation success increases with age.
Scientists shed light on braking mechanisms in cellular signaling
A team of researchers studying a flowering plant has zeroed in on the way cells manage external signals about prevailing conditions, a capability that is essential for cells to survive in a fluctuating environment.
How planarians maintain their stem cell pools over generations
Planarians are known as masters of regeneration: they can re-build any part of their bodies after amputation. This ability relies on a large number of pluripotent stem cells. To further investigate the mechanisms ...
DREAM project crowdsources answer to cancer cell drug sensitivities
A study published June 1 in the journal Nature Biotechnology describes the results of an open challenge to predict which breast cancer cell lines will respond to which drugs, based only on the sum of cells' genomic data. ...
