Carbon fibre for more performance & economy

Credit: Charged EVs

Weight is the enemy of acceleration, handling, braking & economy in a vehicle.

For this reason, manufacturers invest a substantial effort in weight reduction. Perhaps the most obvious method of weight reduction is choice of structural materials. Steel is the major structural material of most vehicles because of cost.

Carbon fibre is both lighter & stronger than steel. It also more expensive, because of the labour-intensive methods used in its production.

Carbon fibre is extensively used in racing cars & aircraft. BMW has made extensive use of carbon fibre in its i3 electric vehicle & i8 extended-range electric performance car.

Before carbon fibre can be more widely used, however, price must be reduced. Essentially, this means elimination of the expensive manual component. I.e. automation.

Klaus Drechsler, head of MAI Carbon Cluster Management GmbH, a research programme supported by the German govenment & BMW among others, told Bloomberg that they have, "reached a halfway point":

Apple Pay/CurrentC — another standards war — this time in mobile payments

In USA, a large drug store chain (Rite Aid) has stopped taking payments through Apple Pay. Reason appears to be their interest in an alternative system, CurrentC, which is also backed by such heavyweights as Wal-Mart, Best Buy, Target, Darden Restaurants & Sears.

CurrentC has two problems:
● it won't be operational until 2015 — so customers will have to wait
● based on the information available, customers will be required to link their account to the CurrentC system, & at the time of making a payment, will have to use their phone to scan a QR code displayed on the merchant's terminal

An attempt to carve out a piece of electronic payments, in this way, is likely to be as attractive to customers as a business accepting only one type of credit card.

Fitness bands too expensive? How about $1 per month? – updated

Credit: Pivotal Living

Not convinced? Pivotal's Life Tracker 1 fitness band also comes with optional free replacement every year two years. At that time, your total cost is $12 $24 + if you renew, you get a free update to the latest model.

Compare that with the up-front-cost of any another tracker.

Update: apparently, at this time, its pre-order, in the USA only. Other areas promised for 2015.

Promising method for detecting pancreatic cancer years before traditional diagnosis

Early detection of a cancer means much better chance of a cure. Some cancers, such as skin & breast cancer are relatively easy to detect early because they can be detected by sight or touch. Others, such as pancreatic cancer as more difficult.

Recently, a high level of certain amino acids has been found to indicate an elevated risk of pancreatic cancer years later.
