Cell-Free Artificial Photosynthesis with Frog Foam

by Michele in Promega Connections

We owe a lot to frogs and toads. They help us welcome in spring and summer with their peeps, croaks and snores in the evenings. They serve as bioindicator species that alert us to damaged or toxic environments. And, now, they may even help us kick the fossil fuel habit. Biofuels, based on harvesting and [...]... Read more »

“Privatizing” the Reviewer Commons?

by jebyrnes in I'm a chordata, urochordata!

Let’s face it. The current journal system is slowly breaking down – in Ecology if not in other disciplines as well. The number of submissions is going up exponentially. At the same time, journals are finding it harder and harder to find reviewers. Statistics such as editors contacting 10 reviewers to [...]... Read more »

Just say no to sunscreen nanophobia!

by sciencebase in Sciencebase Science Blog

Once again we’re at a pivotal point in human development, where a novel technology might allow us to improve the lot of millions, perhaps billions of people across the globe and yet activists are invoking the precautionary principle and informing consumers of the possible dangers therein. As happened with vaccines, nuclear energy, genetically modified crops, [...]Just say no to sunscreen nanophobia! is a post from: Sciencebase Science Blog

Perception of Supply Risk

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

One of the most published supply risk researchers is George A. Zsidisin. In his 2003 article he describes the characteristics of inbound supply that affect the perception of risk.

Supply Risk
The author defines supply risk as the potential occurrence of an incident associated with inbound supply from individual supplier failures or the supply market, in which its outcomes result in the inability of the purchasing firm to meet customer demand or cause threats to customer life and safety.
He........ Read more »

Designer Genes

by Jessica Harvey in Berkeley Science Review Blog

Synthetic biology is a promising field of research that aims, in part, to engineer organisms to produce medicines and biofuels. Its allure lies in using biological building blocks and pathways, already exquisitely designed by nature, to produce essential materials for human use (instead of trying to re-invent everything ourselves from scratch).

Disruption-Management Strategies for Short Life-Cycle Products

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

In his 2009 paper Brian Tomlin analyzes strategies to mitigate disruption risks in a three echelon supply chain.

Focus in his research is a single company, with its suppliers and customers. The objective is to maximize expected utility, while demand and supply are uncertain. There are two products available which can be used as substitutes. The time horizon for the decision maker is one season where the products can be sold.

Three different sourcing structures are considered.

Cyber attacks are criminal

by David Bradley in SciScoop Science Forum

The internet, electronic communications channels and computer technology that controls critical infrastructure together represent a new combat front on the international political stage. Several nations have been accused recently of cyber attacks, not least Russia and China, on the data centres of other governments. Whole power supply systems have been compromised on occasion and even [...]... Read more »

Design of Agile Supply Chains

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

I already reviewed two other articles about agile supply chains. One on the role of distribution centers in supply chains and one on the migration from lean to agile supply chains.

But the question comes to mind if lean and agile supply chains have to be mutually exclusive or if it is possible to combine them. Christopher and Towill (2001) had a look at this question regarding the supply chain design. Continue reading "Design of Agile Supply Chains"

Regeneration of Tooth Enamel: Cavities Healed in Mice

by Reason in Fight Aging!

Dental researchers are forging ahead with their branch of tissue engineering and regenerative medicine. It hasn't been long since engineered growth in situ of replacement teeth was demonstrated in rats, and now a research group has shown they can regenerate tooth enamel in mice, thereby healing cavities: A new peptide, embedded in a soft gel or a thin, flexible film and placed next to a cavity, encourages cells inside teeth to regenerate in about a month ... The gel or thin film contains a pepti........ Read more »

Cultural Induction is Hard

Chater and Christiansen (2010) argue that learning culturally transmitted systems such as language are easy to learn because they have adapted to learner's biases, so their intuitions will likely be correct. I argue against this using grammaticality judgements of Welsh.... Read more »

A virtual camera lucida

by Zen Faulkes in NeuroDojo

Sometimes, the scientific literature sucks at getting information to you.

I was looking at the table of contents of a new issue of The Journal of Crustacean Biology and saw an article about how to photograph soft-bodied crustaceans. Hm, I wonder why photographing soft-bodied crustaceans is difficult, I thought.

And the abstract mentioned software to deal with short focal planes by merging several pictures. The software is Helicon Focus.

Yes, I should be happy that I have found something usefu........ Read more »

Supply Chain Performance and its topological features

by Daniel Dumke in SCRM Blog - Supply Chain Risk Management

Perhaps this research by Pero et al. can support small and medium sized companies with the design and redesign of its supply chain network.
The goal of the study was to analyze the connection between topological features of the supply chain and the resulting supply chain performance.

Method and Model
The authors used simulation techniques and statistical analysis to simulate a pull based supply network. The network consists of a retailer-, distributor- and manufacturer-level.
