Development assistance for health has increased substantially since 1990 for low-income countries

Funding for health in developing countries has increased substantially since 1990, with a focus on HIV/AIDS, maternal health, and newborn and child health, and limited funding for noncommunicable diseases, according to a study in the June 16 issue of JAMA.

Herding:instinct or heuristics?

Many previous studies regarded herding as a kind of instinctive behavior. Now researchers in Tsinghua university compare herding behavior in mice under real-fire and simulated-fire conditions,proved that herding is not instinct but a heuristic strategy that corresponds to ecological rationality. During a real fire, if the individual has an implicit memory associated with escape, priority is given to this knowledge instead of the herding heuristic.

Genetic switch determines egg or sperm

New experiments in the Japanese rice fish show that the fox13 gene appears to be the switch that determines whether a germ cell becomes an egg or sperm cell. The finding could help researchers learn more about how the sexual fate of germ cells is determined during vertebrate development.

Reactivating fault slip with fluid injection

Water injected into an inactive fault can cause aseismic slip along the fault -- movement without detectable earthquakes -- that may then indirectly lead to micro-earthquakes.

Night vision in tune with nature in hovering hawkmoths

How do nocturnal insects forage so successfully in the twilight and darkness? A new study by Simon Sponberg and colleagues suggests that the vision of the hawkmoth Manduca sexta, which hovers in place and feeds on nectar at dawn and dusk, is finely attuned to the swaying of flowers in the breeze.

Isolation and characterization of human hepatocytes and non-parenchymal liver cells

In recent years, human liver cells have gained increasing importance in research, e.g. for studies on drug toxicity or the development of disease models. For in vitro testing primary human hepatocyte cultures are currently considered as the “gold standard”. Co-cultivation with non-parenchymal liver cells (NPC) could be used to further improve in vitro liver models, thus reflecting the in vivo situation closer than current state of the art models.

Genetically Modified Fish on the Loose?

Transgenic fish may soon enter commercial production, but little is known about their possible effects on ecosystems, should they escape containment. Further, risk-assessment efforts are often hampered by an inability to comprehensively model the fishes’ fitness in the wild.

T cells smuggle nanomedicine into tumors

T cells can serve as “Trojan horses” to smuggle drug-loaded nanoparticles into lymphoma tumors, which could improve efficacy of chemotherapy, a new study shows in mice. The results suggest that T cells can enhance delivery of drugs to hard-to-reach tumors in lymphomas and potentially other types of cancer.

As one of the ‘‘neglected’’ tropical diseases, dengue is affecting substantially increasing number of people and proportion of global population. An article published on Science Bulletin summarized the most recent data about dengue outbreaks in China and reviewed the global trend of dengue epidemiology. Future directions for dengue surveillance, control and prevention are also introduced.

Introduction to holographic superconductor models

In the last years it has been shown that some properties of strongly coupled superconductors can be potentially described by classical general relativity living in one higher dimension, which is known as holographic superconductors. A paper gives a quick and introductory overview of some holographic superconductor models with s-wave, p-wave and d-wave orders in the literature from point of view of bottom-up, and summarizes some basic properties of these holographic models in various regimes.

Hypoxia in estuaries

Both anthropogenic and climate effects may modulate the health of fish nurseries in coastal estuaries, according to a study. Estuarine nurseries are among the coastal ecosystems known to be sensitive to anthropogenic stressors, such as increasing nutrient inputs that can lead to algal blooms and hypoxic conditions.

Imaging diffusion through the human nail

Researchers report that solvents diffuse through the human nail in a size- and concentration-dependent manner. Treating nail diseases, such as fungal infections, is difficult because the tightly woven keratin network of the nail acts as a barrier to efficient drug delivery.

Neurons in the crow brain respond to numbers of objects, enabling quantitative perception and discrimination similar to primates, according to a study. Birds demonstrate an ability to quantify numbers of objects despite lacking the six-layered neocortex brain structure thought to be responsible for cognition in primates.

Mathematical modeling may help estimate extinction rates among poorly assessed species, according to a study. Species extinctions in recent decades have raised concerns that Earth is currently experiencing a mass extinction, yet fewer than 800 modern species, out of around 1.9 million known species, are positively recorded as extinct.

The antidepressant ketamine may act by stimulating a region of the brain’s prefrontal cortex, according to a study. Ketamine can produce rapid and long-lasting antidepressant effects, yet the drug’s potential for side effects and abuse limits its widespread use, and the cellular mechanisms of ketamine’s effects are not yet known.

Meta-analytic of the effects of different anti-aging drugs on survival curves of C. elegans

Survival records of longevity experiments remain the most indispensable method in aging-related research in spite of the development of technology. There have been very few cross-study analyses to determine the pattern differences of these anti-aging strategies in survival curves. A recent research address this question by conducting a comprehensive and comparative meta-analysis on a wealth of published studies.
