Why People Believe in Conspiracy Theories [Preview]

Conspiracy theories offer easy answers by casting the world as simpler and more predictable than it is. Their popularity may pose a threat to societal well-being
Suspicious Minds

People who believe in one conspiracy theory are likely to espouse others, even when they are contradictory.
Conspiracy ideation is also linked with mistrust of science, including well-established findings, such as the fact that smoking can cause lung cancer.
Mere exposure to information supporting various fringe explanations can erode engagement in societal discourse.

‘Artificial nose’ scents blood-poisoning bacteria

An “artificial nose” that could save lives by swiftly sniffing out blood-poisoning bacteria has been developed by scientists.

The device can test for the bugs in just 24 hours instead of the usual 72 and researchers hope it can be used to prevent sepsis, a potentially fatal condition. In some cases it can rapidly lead to septic shock, organ failure and death. An estimated 20 to 35 per cent of victims die.

The new device consists of a small plastic bottle with a chemical-sensing array or artificial nose attached to the inside. A blood sample is injected into the bottle, which is then shaken to agitate a nutrient solution and encourage bacteria to grow.

Climate change will upset vital ocean chemical cycles

Climate change will upset vital ocean chemical cycles
Published: Sunday, September 8, 2013 - 13:31 in Earth & Climate

New research from the University of East Anglia shows that rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorus. Plankton plays an important role in the ocean's carbon cycle by removing half of all CO2 from the atmosphere during photosynthesis and storing it deep under the sea -- isolated from the atmosphere for centuries.

Findings published today in the journal Nature Climate Change reveal that water temperature has a direct impact on maintaining the delicate plankton ecosystem of our oceans.

The new research means that ocean warming will impact plankton, and in turn drive a vicious cycle of climate change.

Upcoming conference on science journals
an upcoming science communication conference that you might be interested in attending or promoting. The topic of this conference is the evolving relationship between science journals and libraries, public education, research collaboration, university tenure, intellectual property rights, public policy, and more. Click here to view the event page.

This conference is being organized by the National Science Communication Institute (nSCI), a Seattle-based nonprofit whose mission is to improve the communication that happens inside science. You can read more about our group at www.nationalscience.org.

As far as we know, this will be one of the first conferences (if not the first) to really tackle the issue of journals head-on. Our hope is that we can share the knowledge and perspectives gained from this event, and then host other regional conferences and/or a national conference on this subject in 2014 with the goal of finding some common ground for change and improvement in how science journals intersect with research, education, policy, tenure, and more.

Rating the Best Ways to Study

Some study methods work in many different situations and across topics, boosting test performance and long-term retention. Learning how to learn can have lifelong benefits.
Self-testing and spreading out study sessions—so-called distributed practice—are excellent ways to improve learning. They are efficient, easy to use and effective.
Underlining and rereading, two methods that many students use, are ineffective and can be time-consuming.
Other learning techniques need further testing and evaluation. In the meantime, students and teachers can put proved study methods to use in classrooms and at home.

Poor Choices: Financial Worries Can Impair One’s Ability to Make Sound Decisions

New research suggests causative link between income level and cognitive function

The findings are detailed in the August 30 issue of Science.

New work by a team of psychologists and economists supports the notion that humans have limited bandwidth for decision-making. And the capacity to make choices can take a hit once that cognitive load becomes too heavy. The research, based on experimental data collected on people with varying levels of self-reported income in rural India and a New Jersey shopping mall, concludes simply that at least short-term financial stress can max out our mental reserves on par with the level of impairment that results from pulling an all-nighter.

Alternative issues that demand attention, such as calorie counting in a diet, also could reduce cognitive abilities. The difference with money, however, is that one can end a diet anytime; not so with financial stress.

These new results also support other research on an overlapping area of study—an emerging field called self-control, says Kathleen Vohs, a consumer behavior expert at the University of Minnesota who published an accompanying commentary piece on the findings in the same issue of Science.* Self-control studies look at the finite ability of individuals to overcome urges and make decisions. They posit, in a similar vein, that when individuals are faced with many decisions that demand trade-offs—such as a scarcity of food, time or money—and do not have a chance to recover from the resulting brain drain, self-control can tank. That depletion, in turn, could lead to decision-making patterns that impede one’s ability to improve their lot in life, she says. “Because the poor must overcome more urges and make difficult decisions more often than others, they are more likely to overeat, overspend and enact other problematic behaviors,” she wrote.

Computer Game-Playing Shown to Improve Multitasking Skills

A new study reveals, despite polarized opinion about brain-training packages, that playing a 3-D race car-driving video game reduced cognitive decline in subjects aged 60-85

Highlights

•

We demonstrate the fabrication of flexible, transparent microfluidic layers for window or solar panel cooling.
•

Experimental evaluation of cooling rates for fluidic layers as a function of flow rate, temperature.
•

Heat transfer model to evaluate the experimental results, and design scaled up implementation.
•

Optical absorption measurements, as a function of fluidic composition and color change.
•

Incorporating fluidic flow is a means to develop adaptive solar and window technologies.

Abstract

Windows are a major source of energy inefficiency in buildings. In addition, heating by thermal radiation reduces the efficiency of photovoltaic panels. To help reduce heating by solar absorption in both of these cases, we developed a thin, transparent, bio-inspired, convective cooling layer for building windows and solar panels that contains microvasculature with millimeter-scale, fluid-filled channels. The thin cooling layer is composed of optically clear silicone rubber with microchannels fabricated using microfluidic engineering principles. Infrared imaging was used to measure cooling rates as a function of flow rate and water temperature. In these experiments, flowing room temperature water at 2 mL/min reduced the average temperature of a model 10×10 cm2 window by approximately 7–9 °C. An analytic steady-state heat transfer model was developed to augment the experiments and make more general estimates as functions of window size, channel geometry, flow rate, and water temperature. Thin cooling layers may be added to one or more panes in multi-pane windows or as thin film non-structural central layers. Lastly, the color, optical transparency and aesthetics of the windows could be modulated by flowing different fluids that differ in their scattering or absorption properties.
Graphical abstract

A transparent, bio-inspired, convective cooling layer for building windows and solar panels has been developed to help reduce heating by solar absorption. The windows contain a vasculature network of millimeter-scale, fluid-filled channels. The design maintains a continuous flow of water to directly cool the window surface or change the optical absorption.
