Researchers have provided an important road map to conserving rough-nosed horned lizards in Sri Lanka.
Study Finds Variation Within Species Is A Critical Aspect Of Biodiversity（图）
Variation Within Species Critical Aspect Biodiversity
2017/12/19
Concerns about biodiversity tend to focus on the loss of species from ecosystems, but a new study suggests that the loss of variation within species can also have important ecological consequences.Man...
Climate’s Effects on Flowers Critical for Bumble Bees（图）
Climate Flowers Critical Bumble Bees
2017/10/25
Climate change can influence consumer populations both directly, by affecting survival and reproduction, and indirectly, by altering resources. However, little is known about the relative importance o...
Gene network controls how many flowers and fruits plants will produce during critical growth window
Gene network controls flowers and fruits plants critical growth window
2016/11/29
There is staggering diversity in the number of flowers produced by each of the 2,800 or so species of plants in the nightshade family, which includes economically important crops such as tomatoes, pep...
Electric Field-Induced Critical Demixing in Lipid Bilayer Membranes
Cardiolipins Electric Stimulation Electricity Fluorescent Dyes Lipid Bilayers Membranes, Artificial Microscopy, Fluorescence Models, Chemical Models, Molecular hosphatidylcholines Phosphatidylethanolamines Thermodynamics
2016/5/23
Electric fields can induce lateral reorganization of lipids in fluid bilayer membranes. The resulting concentration profiles readily are observed in planar-supported bilayers by epifluorescence micros...
Event-rate and delta inflation when evaluating mortality as a primary outcome from randomized controlled trials of nutritional interventions during critical illness: a systematic review
critical illness delta inflation enteral nutrition parenteral nutrition clinical trial mortality nutrition therapy
2018/11/29
Background: There is a lack of high-quality evidence that proves that nutritional interventions during critical illness reduce mortality.
Hippocampal Context Processing is Critical for Interference Free Recall of Odor Memories in Rats
hippocampus context interference
2015/8/7
Interference is a critical problem for memory systems and a primary cause of retrieval failure. One strategy for minimizing interference is to associate the items to be remembered with the context in ...
Transcriptional regulation of ATF4 is critical for controlling the Integrated Stress Response during eIF2 phosphorylation
Transcriptional regulation ATF4
2015/5/25
In response to different environmental stresses, phosphorylation of eIF2 (eIF2P) represses global translation coincident with preferential translation of ATF4. ATF4 is a transcriptional activa...
New lab technique simultaneously reveals structure and function of proteins critical in DNA repair
structure and function proteins critical DNA repair
2015/4/29
By combining two highly innovative experimental techniques, scientists at the University of Illinois at Urbana-Champaign have for the first time simultaneously observed the structure and the correlate...
Critical transport: Bond LSC team finds boron vital for plant stem cells, corn reproduction（图）

2014/9/1
Carbon’s next-door neighbor on the periodic table typically receives little attention, but when it comes to corn reproduction boron fills an important role.
Prior Upper Body Exercise Reduces Cycling Work Capacity but Not Critical Power
POWER–DURATION RELATIONSHIP METABOLITES ARM CRANKING CYCLING
2017/5/19
This study examined whether metabolite accumulation, induced by prior upper body exercise, affected the power–duration relationship for leg cycle ergometry.
Quantifying Limits to Detection of Early Warning for Critical Transitions
early warning signals tipping point alternative stable states likelihood methods
2012/5/2
Catastrophic regime shifts in complex natural systems may be averted through advanced detection. Recent work has provided a proof-of-principle that many systems approaching a catastrophic transition m...
Canalization in the Critical States of Highly Connected Networks of Competing Boolean Nodes
Competing Boolean Nodes Highly Connected Networks
2011/9/13
Canalization is a classic concept in Developmental Biology that is thought to be an important feature of evolving systems. In a Boolean network it is a form of network robustness in which a subset of ...
Competition, coexistence, and critical behaviour in a lattice tumor-growth model
Competition coexistence critical behaviour lattice tumor-growth model
2010/11/15
In the present paper we study a lattice tumor-growth model. Monte Carlo simulations for $d=$1, 2, and 3 show that when nutrients are easily available, normal and tumor cells coexist. However, when the...
