Sex is 'nothing but trouble', geneticist says

(Phys.org) —Sex determining genes in marsupials have shed some light on how the Y chromosome, which determines the male sex in humans, will quickly degenerate and eventually disappear, according to a world-renowned evolutionary ...

Why smart growth frustrates players in the system: study

Maryland planners, developers and land-use advocates consider the state's smart growth tools too weak, frustrating their desire for development within existing urban areas, finds a new University of Maryland study based on ...

Making systems robust

The human body keeps the calcium concentration in the blood constant, similarly to an aircraft's autopilot keeping the plane at a constant altitude. What they have in common is that both the body and the autopilot employ ...

EPA proposes rewrite of rules on lead contamination in water

The Trump administration on Thursday proposed a rewrite of rules for dealing with lead pipes contaminating drinking water, but critics say the changes appear to give water systems decades more time to replace pipes leaching ...

New mechanism for growth control discovered

Research on Drosophila reveals that once activated during starvation, this regulatory system prevents the secretion of insulin like peptides, the counterparts of IGF and insulin in mammals.

Improving crops from the roots up

Research involving scientists at The University of Nottingham has taken us a step closer to breeding hardier crops that can better adapt to different environmental conditions and fight off attack from parasites.

Cell signaling classification system gives researchers new tool

Using ever-growing genome data, scientists with the Department of Energy's (DOE) Oak Ridge National Laboratory and the University of Tennessee are tracing the evolution of the bacterial regulatory system that controls cellular ...
