Also of interest from the Proceedings of the National Academy of Sciences

Surveys of 5,300 Germans in 1996 and 2006 find that Germans born in the 1920s and 1930s and who were exposed to Nazi anti-Semitic messages as children express stronger anti-Semitic beliefs, on average, than Germans born before or after that time, suggesting the extent and effectiveness of policy intervention efforts to influence beliefs.

Green spaces and cognitive growth in children

A study reports a link between exposure to green spaces at school and cognitive development in primary schoolchildren. Patches of greenery in cities packed with buildings are thought to have a positive effect on cognitive development in children, but few studies have uncovered population-level evidence for such a link.

How moon jellies repair asymmetry

In response to losing limbs, the moon jelly reorganizes remaining body parts to recover its essential symmetry, according to a study. Evolution has endowed animals with the capacity to recover from injuries, ranging from wound healing to regenerating lost body parts.

Seasonal vitamin D deficiency and HIV progression

Vitamin D supplementation may help reverse seasonal nutritional deficiency and slow HIV progression in Cape Town, South Africa, according to a study. Because vitamin D is associated with immune system function, deficiencies can affect the outcome of diseases, including infection with HIV.

Environmental fluctuations and dinosaur dominance

Climate and plant community instability may have hampered the success of dinosaurs in tropical latitudes during the Triassic Period, according to a study. Although dinosaurs ecologically dominated high latitudes before the end of the Triassic, they were rare in tropical latitudes, with few species present, for up to 30 million years after their origin.

Trial compares antibiotics vs appendectomy for treatment of appendicitis

Among patients with uncomplicated appendicitis, antibiotic treatment did not meet a prespecified level of effectiveness compared with appendectomy, although most patients who received antibiotic therapy did not require an appendectomy, and for those who did, they did not experience significant complications, 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.

Dengue: what it is and why there is more

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.
