Back in black: record efficiency for black-silicon solar cell

by Jonathan Trinastic in Goodnight Earth

Crystalline silicon solar cells are reaching their efficiency limit and manufacturing costs. But a new method to create black-silicon solar cells, potentially cheaper, has led to a record 22.1% efficiency. Learn about the physics behind the record here!... Read more »

Hermit Houses And Fiddler Claws

by Mark Lasbury in As Many Exceptions As Rules

Fiddler crabs are an evolutionary marvel. Their major claw is huge, it plays a role in mate selection, but not just in the way you’d think.
Some species are right-clawed and some can have the major claw on either side, but if they lose one and grow it back, the major claw might switch sides! The new major claw isn’t as good for fighting, so he fakes being strong and tries to win without fighting.

What To Do About A Slow Peer Reviewer?

by Neuroskeptic in Neuroskeptic_Discover

An amusing editorial in the neuroscience journal Cortex discusses the excuses scientists use to explain why they didn't submit their peer reviews on time:
Following our nagging for late reviews, we learned that one reviewer had to take their cat to the vet, another was busy buying Christmas presents, one was planning their holidays, an unfortunate one had their office broken into [...] others agreed to review whereas indeed they really intended to withdraw, or were just too busy to reply.

Supply Chain vs. Supply Chain Competition

by Andreas Wieland in Supply Chain Management Research

Many theory-testing efforts in our field are made by borrowing theories from other fields (e.g., transaction cost economics or resource-based theory), adapting them to a supply chain context and deriving hypotheses that are eventually tested statistically. By doing so, we have reached a lot! But we also need our own theories. For example, several years […]... Read more »

Predicting the onset of schizophrenia?

by Paul Whiteley in Questioning Answers

"A lower level of inflammatory response indicated by PTX3 [pentraxin-3] might be implicated in developing schizophrenia."That was the primary conclusion reported by Natalya Weber and colleagues [1] (open-access here) who "tested preonset serum specimens from 160 US military service members who were later diagnosed with schizophrenia or bipolar disorder and 160 matched controls without psychiatric disorders."PTX-3 by the way, is a compound of some note when it comes to the concept of inflammation, residing in the same family as a better known inflammatory-related compound, C-reactive protein (CRP) (see here). The difference between CRP and PTX-3 seems to be down to CRP being a 'short' pentraxin and PTX-3 being a 'long' one.Weber et al assessed levels of PTX-3 in "first available serum specimens" of 160 military personnel who were "later diagnosed with schizophrenia or bipolar disorder" (n=80 respectively) and compared them with 160 matched controls. As per other work by authors on the Weber paper [2], using military cohorts has some significant advantages when it comes to potential biomarker work in this area (see here). They reported that: "PTX3 levels among subjects with schizophrenia were significantly lower... than the levels among their paired controls" thus indicating that prior to the onset of schizophrenia, PTX-3 levels might be something to watch for risk of developing the condition. The authors even went as far as to say that: "a level of PTX3 below the median (0.6 ng/ml) was associated with an OR [odds ratio] of 3.0 (CI, 1.6–5.7)" when it came to risk of subsequent schizophrenia.This is interesting data which, as the authors point out, is strengthened by "including the follow-up of an initially disease-free population with subsequent complete and reliable case/control ascertainment" alongside the collection of biological samples "years before disease onset". Military personnel are screened and screened over their time serving, thus making this population about as valuable to research as all those archived newborn bloodspot cards that I'm so interested in (see here). The authors do caution that their results may not be entirely generalisable to the population at large as a result of their 'captive audience' (how many civvies spend their days like military personnel?) but the strengths of the study perhaps outweigh the limitations.The idea that the immune system and the orchestration of its arsenal of compounds might be perturbed when it comes to a behavioural/psychiatric condition like schizophrenia is by no means a new idea (see here for example). That being said, science is still fumbling around trying to make sense of the idea that immune function / inflammation might impact on something like schizophrenia and the specific hows and whys of the relationship. Weber et al do speculate on what their results might mean as per comments that: "Long-lasting or temporal lack of PTX3 could potentially impact pathogen recognition, activation, and orientation of the adaptive immune response and/or antibody production." Further: "Impairment of any of these functions, particularly those where PTX3 plays its unique role, could lead to a vulnerability to the neurotropic pathogens associated with schizophrenia and bipolar disorder." Part of those 'neurotropic pathogens' must surely include the body of work referring to a possible role for Toxoplasma gondii in relation to some schizophrenia (see here).Interestingly also the authors talk about how their findings might relate to the issue of autoimmunity and how their findings might be contributory to immune system "derailment into a dysregulated state of autoimmune activation and damage." As per my discussions on autism and autoimmunity (see here for example) I do think there is a lot more to see in this particular area with schizophrenia also in mind (see here), perhaps also mediated by some interesting connections to the human endogenous retroviruses (HERVs) among other things. And yes, before you ask, HERVs have been implicated in cases of schizophrenia and perhaps even with the words 'molecularly mimicry' and 'superantigen' in mind [3].More research in this area please.Music: Björk - Hyperballad.----------[1] Weber NS. et al.

Can monies spent globally on journal subscriptions be completely transitioned to an OA business model to free the journals?

by SciELO in SciELO in Perspective

The recent rapid growth in open access publishing, and the clear benefits that open access presents to society as a whole leads to the question: can all subscription based scientific journals in the world be transitioned to open access in a sustainable way? Is there enough money currently in the system for such a transition, and would there be any economic impact? A recent eye-opening study published by the Max Planck Digital Library delves into this issue and provides some very concrete answers based on real expenditures in subscriptions and on the real costs of open access services. … Read More →...

Babies can think before they can speak

by Dr. Jekyll in Lunatic Laboratories

Two pennies can be considered the same — both are pennies, just as two elephants can be considered the same, as both are elephants. Despite the vast difference between pennies and elephants, we easily notice the common relation of sameness that holds for both pairs. Analogical ability — the ability to see common relations between objects, events or ideas — is a key skill that underlies human intelligence and differentiates humans from other apes.... Read more »
