Live cell imaging reveals distinct alterations of subcellular glutathione potentials

Glutathione is the most abundant cellular redox buffer that both protects cells from oxidative damage and mediates cellular signaling. Perturbation of glutathione balance has been associated with tumorigenesis; however, due to analytical limitations, the underlying mechanisms behind this relationship are poorly understood. Utilizing a recently developed genetically encoded redox-sensitive probe has revealed differentially regulated redox environments within cellular compartments, and evidence of the contributory role of the p53 protein in supporting cytosolic redox poise.

Turning off depression in the brain

Previous studies have shown that when the currents of cation channels are elevated in mice, dopamine neurons in the ventral tegmental area (VTA) of their brains can become hyperactive and, in turn, the rodents become depressed.

Study finds global changes in biodiversity, not loss

Although human activity has accelerated the rate of species’ extinction around the world, there has not been a consistent loss of biodiversity across marine and terrestrial habitats, researchers say. Instead, it’s the composition of species that has been systematically changing from ecosystem to ecosystem, according to a new study.

A distant planet rather like Earth

Scientists scouring the sky have found a planet roughly Earth's size that could theoretically host liquid water, a new study reports. This is a landmark on the road to discovering habitable planets orbiting stars besides our Sun.

Comparing methylation maps of archaic and modern humans

Sequencing ancient DNA has helped scientists learn about the genetic changes that separate modern humans from their closest extinct relatives, Neandertals and Denisovans, and now, according to a new report, scientists better understand how epigenetics influenced differences among these groups, too.

Oral drug stops early neasles infection in its tracks

Measles is making a comeback. Despite the existence of an effective vaccine for the highly-infectious respiratory virus, the recent decline in vaccination compliance in some countries has led to an increase in sporadic outbreaks of the disease. Now, researchers have developed an oral drug that blocks a measles-like virus during the early stages of infection in ferrets.

How can the plants of different functional groups adapt to tropical karst habitat?

Investigation of the eco-physiological mechanisms of plant adaptation to the tropical karst habitat can contribute important knowledge to the restoration of desertified kart lands. The present study found that evergreen trees, deciduous trees and woody lianas co-occurring in tropical karst forest differed significantly in their drought tolerance and water use, and which are very important for the maintaining of water balance in a karst forest ecosystem. This study has been published on SCIENCE CHINA Life Sciences(In Chinese), 2014, No.3.

A study finds that glaciers in Scotland during the Younger Dryas cool period retreated rather than grew, a finding attributed to changes in North Atlantic circulation during the Younger Dryas that led to warm summers and early deglaciation in Scotland.

Drought increases tree mortality in the Amazon

A study finds that drought significantly increases fire-related tree mortality in the Amazon rainforest. Drought poses a significant threat to the Amazon due to the increased risk of severe wildfire during dry years. Recent droughts in 2007 and 2010 led to wildfires burning 12% and 5% of the Amazon, respectively.

Genetic analysis reveals evolution of flesh-eating bacteria

Researchers have determined the evolutionary path that turned a benign microorganism into a pathogen that causes necrotizing fasciitis. Despite decades of study, epidemics represent a considerable threat to human health, partly because researchers have been unable to pinpoint the nature and timing of key molecular events that turn some microbes into virulent pathogens.

Glucose and aggression in married couples

A 21-day study of daily blood glucose levels in married couples finds that decreased blood glucose, which is related to self-control, correlated with increased aggressive behavior toward participants’ spouses. Self-control requires energy in the form of blood glucose, and this energy can be depleted over time, leading to an erosion of self-control.

LP-assisted and open total gastrectomy for advanced proximal gastric cancer without serosa invasion

This research suggested that compared with open total gastrectomy (OTG), laparoscopy-assisted total gastrectomy (LATG) with extended lymphadenectomy in patients with advanced gastric cancer (ACG) without serosa invasion had minimally invasive and better postoperative recovery. While, there were no significant differences in the number of dissected lymph nodes, postoperative morbidity, and the survival curves between the two groups.

Now, a new study reveals how Drosophila melanogaster, or the common fruit fly, is able to execute such instantaneous evasive flight maneuvers -- and the fruit flies’ technique is not what researchers had imagined.

Renal denervation for resistant hypertension: one-year experience from China

The researchers from Fuwai Hospital reported 12-month outcomes of renal denervation from the first prospective study in China using the Symplicity device. This study showed that renal denervation may be an effective interventional strategy in lowering blood pressure of Chinese patients with resistant hypertension, with minimal adverse events at 12-month follow up.
