24 hours of sleep deprivation can lead healthy people to a condition similar to the symptoms of schizophrenia, which could serve as a model system for the development of drugs to treat psychosis.

In psychosis, there is a loss of contact with reality and this is associated with hallucinations and delusions. The chronic form is referred to as schizophrenia, which likewise involves thought disorders and misperceptions. Affected persons report that they hear voices, for example.

When it comes to public understanding of science, science blog readership doesn't help poor people, it actually hurts.

Similar levels of attention to science in newspapers and on blogs can lead to vastly different levels of factual and perceived knowledge. Notably, frequent science blog readership among low socioeconomic-status groups actually lowered their scores on factual tests of scientific knowledge, while high levels of attention to science in newspapers caused them to feel they were less knowledgeable compared to those who read less or those from higher socioeconomic backgrounds.

When did teen dating get so violent? It used to be the kind of thing that was a plot linchpin for movies but now estimates are that 1 in 6 young people report acts like punching, pulling hair, shoving, and throwing things. 

Changes to Antarctic winds have been implicated in southern Australia's drying climate but a new estimate says they may also have a profound impact on warming ocean temperatures under the ice shelves along the coastline of West and East Antarctic.

China's richest provinces are having a huge environmental impact on the country's water-scarce regions, according to a new estimate by the International Institute for Applied Systems Analysis (IIASA) and the University of Maryland.

Soot and methane were little-considered factors in climate change models a decade ago but with the drop of CO2 in Western nations, activists have begun to worry about those. 

It would have been smart to factor them in all along. Every year, wildfires clear millions of hectares of land and emit around 34 percent of global soot mass into the atmosphere. In remote parts of Southeast Asia and Russia, these fires can contribute as much as 63 percent of regional soot mass. 

The PandaX experiment of China is located in a deep underground laboratory, shielded by 2,400 meters of low radioactive rocks to provide protection for PandaX against cosmic muons. It began operation in March but has no results yet, so they published a technical design report to show the Chinese government they are doing something.

Platonic solids are regular bodies in three dimensions, such as the cube and icosahedron, and have been known for millennia. They feature prominently in the natural world wherever geometry and symmetry are important, for instance in lattices and quasi-crystals, as well as fullerenes and viruses  

Platonic solids have counterparts in four dimensions. Swiss mathematician Ludwig Schlaefli and Alicia Boole Stott showed that there are six of them, five of which have very strange symmetries. Stott, the third daughter of mathematician George Boole, is best known for establishing the term "polytope" for a convex solid in four dimensions, had a unique intuition into the geometry of four dimensions, which she visualised via three-dimensional cross-sections.

Australia is working to repeal its unpopular carbon tax and replacement strategies to mitigate carbon emissions and stave off future climate change may bring a bonus - water savings. A new study says that the equivalent of one-third of Melbourne's water use could be saved each year through the implementation of efficiency measures.

Researchers at the Monash Sustainability Institute analyzed the water-saving potential of 74 options for reducing greenhouse gas emissions identified in the ClimateWorks Australia Low Carbon Growth Plan for Australia.  An analysis of options to reduce greenhouse gas emissions found energy efficiency measures reduced water consumption at the same time.

Some viruses can hide in our bodies for decades. How do they escape notice and destruction? They have 'fake' human proteins that trick our immune cells into thinking they belong.
