Blood vessels for lab-grown tissues
Researchers from Rice University and Baylor College of Medicine (BCM) have broken one of the major roadblocks on the path to growing transplantable tissue in the lab: They’ve found a way to grow the blood vessels and capillaries needed to keep tissues alive.

Scientists find evidence for ‘chronesthesia,’ or mental time travel
Researchers have found evidence for “chronesthesia,” which is the brain’s ability to be aware of the past and future, and to mentally travel in subjective time. They found that activity in different brain regions is related to chronesthetic states when a person thinks about the same content during the past, present, or future.
In their fMRI study, the researchers asked subjects to repeatedly think about taking a short walk in a familiar environment in either the imagined past, the real past, the present, or the imagined future. By keeping the content the same and changing only the mental time in which it occurs, the researchers could identify which areas of the brain are correlated with thinking about the same event at different times.
The results showed that certain regions in the left lateral parietal cortex, left frontal cortex, and cerebellum, as well as the thalamus, were activated differently when the subjects thought about the past and future compared with the present. Notably, brain activity was very similar for thinking about all of the non-present times.
Because mental time is a product of the human brain and differs from the external time that is measured by clocks and calendars, scientists also call this time “subjective time.” Chronesthesia, by definition, is a form of consciousness that allows people to think about this subjective time and to mentally travel in it.

Your genome in minutes
Scientists from Imperial College London are developing technology that could ultimately sequence a person’s genome in mere minutes, at a fraction of the cost of current commercial techniques.
The researchers have patented an early prototype technology that they believe could lead to an ultrafast commercial DNA sequencing tool within ten years. Their work is described in a study published this month in the journal Nano Letters and it is supported by the Wellcome Trust Translational Award and the Corrigan Foundation.
The research suggests that scientists could eventually sequence an entire genome in a single lab procedure, whereas at present it can only be sequenced after being broken into pieces in a highly complex and time-consuming process. Fast and inexpensive genome sequencing could allow ordinary people to unlock the secrets of their own DNA, revealing their personal susceptibility to diseases such as Alzheimer’s, diabetes and cancer. Medical professionals are already using genome sequencing to understand population-wide health issues and research ways to tailor individualised treatments or preventions.
Dr Joshua Edel, one of the authors on the study from the Department of Chemistry at Imperial College London, said: “Compared with current technology, this device could lead to much cheaper sequencing: just a few dollars, compared with $1m to sequence an entire genome in 2007. We haven’t tried it on a whole genome yet but our initial experiments suggest that you could theoretically do a complete scan of the 3,165 million bases in the human genome within minutes, providing huge benefits for medical tests, or DNA profiles for police and security work. It should be significantly faster and more reliable, and would be easy to scale up to create a device with the capacity to read up to 10 million bases per second, versus the typical 10 bases per second you get with the present day single molecule real-time techniques.”

Amazon hits Hollywood
Amazon.com is getting into the movie business by opening Amazon Studios, with the goal of using the Internet to put fresh movies on the big screen.
The new Internet movie studio will allow writers to upload screenplays to its website, where the global Internet audience can read them and offer feedback, or producers/directors can use them to make test movies. The test movies, which must be at least 70 minutes in length, can also be uploaded.
Amazon Studios will also award monthly cash prizes to the top submissions of $100,000 for the best movie each month and $20,000 to the two best scripts. They’ll also be an annual award of $1 million for the best movie and $100,000 for the best script.
