Insert Coin: LifeBeam heart-monitoring smart cycling helmet (video)

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

Insert Coin LifeBeam heartmonitoring smart cycling helmet video

Let's face it: heart monitors, whether strapped to our chests or mounted to the front of a treadmill, are an awful pain to use. But, those rate readouts can be quite useful while involved in any sort of physical activity, making them a necessary hindrance. A proposed "smart cycling helmet" from LifeBeam, a company best known for its defense products, would serve to simplify things a bit. The solution, which is based on physiological monitoring devices installed in some fighter pilot helmets, would instead serve consumers -- cyclists, specifically. LifeBeam will insert sensors within cycling headgear, letting you capture measurements as you pedal up hills and down city streets.

With included ANT+ and Bluetooth transmitters, the device, which weighs 50 grams and supports up to 15 hours of continuous usage, can feed data to a smartphone or sport watch, for example, letting you track your stats in realtime. LifeBeam has turned to Indiegogo to raise funds for the project, with limited "pre-order" pricing fixed at $149 for the first 200 helmets sold. From there, the price jumps to $189 -- helmets are expected to begin shipping in September of this year. Sound like a fit? Hit up the source link to help the team reach their $50,000 funding goal, or, if you still need a bit of convincing, you can check out the well-produced video embedded just past the break.

Impact Magazine ? Archive ? Album Review: Youth Lagoon ...

In 2011, Trevor Powers AKA Youth Lagoon released The Year of Hibernation, a minimalistic collection of introspective, lo-fi piano ballads dealing with depression and mental trauma. Though I?ve given it the blurb of a DIY psychiatric text book, the album was considered a minor success, appearing on various end-of-year lists and setting in motion a snowballing of expectation about where Powers might venture next.

?Youth Lagoon? Why would you need an alias with a name like Trevor Powers?!? is the usual gag reeled off when you hear people talk about the guy?s music. The two words make a lot more sense as a band name though once you?ve heard a few chords of his sumptuous synth-soaked dream pop; a lot of Powers? lyrical inspiration comes from childhood reminiscences, and he often displays these nostalgic visions in the form of squelchy psychedelic sounds that induce the feeling of far-off lands. This is especially the case on his sophomore LP Wondrous Bughouse, on which Youth Lagoon really finds its feet.

Where The Year of Hibernation was quiet, reflective, sheltered and very reduced sonically, Wondrous Bughouse is expansive, vast, catchy and colourful. If the first record recounted the story of a man literally going into hiding as a way of dealing with his troubles, the second details his release from such self-contained confinement. Having said that, this is not a sunshine album; Trevor is still wrestling with very personal issues but he confronts them in much more expressive, illustrative forms.

A track like ?The Bath? could easily have come from the cutting room floor of the Hibernation sessions, and in a re-imagined form could have slotted quite neatly onto that LP. On Bughouse though, the track is moved a step on from the gentle piano plod which forms its first half. Its second is dissected by a sweet guitar line backed by a hot electric glaze and handful of scratches, rattles and other found sounds which contribute to the overall grander production on the track.

Powers also succeeds in dodging the pitfall of over-production; with a little less TLC, tracks like ?The Bath? or ?Dropla? might have had their emotional pull drained by overpowering sound collages, but Powers reigns his busy hands in to just the right level, protecting the adorability of the songs and maintaining the ?cute and coy? vibe which characterised his debut.

This style poses the marmite equation for many who have listened to Youth Lagoon. The songs on Hibernation were at times overly sweet and cuddly ? fine if you?re a fan of Powers? gumdrop vocals, but, for others, the sound is a little too candy cane saccharine for the refined ear. These moments are certainly less prominent and less off-putting on Bughouse, but they are still there. The piano tune on ?Attic Doctor?, for instance, is modified with gloopy effects which gives its upbeat, skippy melody a confusing cartoon circus/nightmare clown vibe, while the instrumental line on ?Third Dystopia? is so? whimsical it sounds like something off a 90s children?s television show (insert choice of nostalgic reference ? I?m going for Playdays).

While I feel like Powers occasionally lets these goofy sonic references get away from him, he usually channels that sense of childlike innocence mixed with adult desperation effectively. The album?s finest moment is ?Mute? and if you only have time to try one track here, let it be this one. It begins with a bouncy guitar line darting over washes of sweet synth chords before dropping after a minute or so into an onslaught of droney bass intercut with sheathes of slicing guitar and Powers? beautifully vulnerable vocals.

Overall, Wondrous Bughouse is growth for Youth Lagoon. While the composition of tracks has not changed all that much from The Year of Hibernation, there is so much more flesh on them than the bony piano ballads which made up his debut. The coy, indie style is still there but the production is bolder, braver and perhaps proggier than before, contributing to the overall creation of a much more vivid and colourful atmosphere. On its second full-length, Youth Lagoon melds more explosive psychedelic elements with its practised bare-bones indie-pop to create something every bit as colourful and lively as the album?s cover art.

7 genetic risk factors found to be associated with common eye disorder

Monday, March 4, 2013

An international group of researchers has discovered seven new regions of the human genome?called loci?that are associated with increased risk of age-related macular degeneration (AMD), a leading cause of blindness. The AMD Gene Consortium, a network of international investigators representing 18 research groups, also confirmed 12 loci identified in previous studies. The findings are reported online today in the journal Nature Genetics. Supported by the National Eye Institute (NEI), a part of the National Institutes of Health, the study represents the most comprehensive genome-wide analysis of genetic variations associated with AMD.

"This compelling analysis by the AMD Gene Consortium demonstrates the enormous value of effective collaboration," said NEI Director Paul A. Sieving, M.D., Ph.D. "Combining data from multiple studies, this international effort provides insight into the molecular basis of AMD, which will help researchers search for causes of the disease and will inform future development of new diagnostic and treatment strategies."

AMD affects the macula, a region of the retina responsible for central vision. The retina is the layer of light-sensitive tissue in the back of the eye that houses rod and cone photoreceptor cells. Compared with the rest of the retina, the macula is especially dense with cone photoreceptors and is what humans rely on for tasks that require sharp vision, such as reading, driving, and recognizing faces. As AMD progresses, such tasks become more difficult and eventually impossible. Some kinds of AMD are treatable if detected early, but no cure exists. An estimated 2 million Americans have AMD.

Scientists have shown that age, diet, and smoking influence a person's risk of developing AMD. Genetics also plays a strong role. AMD often runs in families and is more common among certain ethnicities, such as Asians and people of European descent.

Since the 2005 discovery that certain variations in the gene for complement factor H?a component of the immune system?are associated with major risk for AMD, research groups around the world have conducted genome-wide association studies to identify other loci that affect AMD risk. These studies were made possible by tools developed through the Human Genome Project, which mapped human genes, and related projects, such the International HapMap Project, which identified common patterns of genetic variation within the human genome.

The AMD Gene Consortium combined data from 18 research groups to increase the power of prior analyses. The current analysis identified seven new loci near genes. As with the previously discovered 12 loci, these seven loci are scattered throughout the genome on many different chromosomes.

"A large number of samples was needed to detect additional genetic variants that have small but significant influences on a person's disease risk," said Hemin Chin, Ph.D., NEI associate director for ophthalmic genetics, who assembled the consortium and helped coordinate the study. "By cataloging genetic variations associated with AMD, scientists are better equipped to target corresponding biological pathways and study how they might interact and change with age or other factors, such as smoking."

The consortium's analysis included data from more than 17,100 people with the most advanced and severe forms of AMD, which were compared to data from more than 60,000 people without AMD. The 19 loci that were found to be associated with AMD implicate a variety of biological functions, including regulation of the immune system, maintenance of cellular structure, growth and permeability of blood vessels, lipid metabolism, and atherosclerosis.

"Like a map that identifies neighborhoods where the electricity has been knocked out by a storm, the AMD Gene Consortium's study effectively tagged regions within the genome where researchers are most likely to find short circuits in DNA that cause AMD," said Anand Swaroop, Ph.D., chief of the NEI Laboratory of Neurobiology and Neurodegeneration and Repair, and one of the group leaders of this consortium effort. "Once you are in the right neighborhood, going block to block or house to house to look for downed power lines goes much faster. Likewise, by limiting their search to the 19 genomic regions identified by the AMD Gene Consortium, scientists can more efficiently search for specific genes and causative changes that play a role in AMD."

As with other common diseases, such as type 2 diabetes, an individual person's risk for getting AMD is likely determined not by one but many genes. Further comprehensive DNA analysis of the areas around the 19 loci identified by the AMD Gene Consortium could turn up undiscovered rare genetic variants with a disproportionately large effect on AMD risk. Discovery of such genes could greatly advance scientists' understanding of AMD pathogenesis and their quest for more effective treatments.

(AP) ? A pre-dawn attack on police in Kenya early Monday killed several officers hours before Kenyans began casting votes in a nationwide election being held five years after more than 1,000 people died in election-related violence.

Police in the coastal city of Mombasa reported a 2 a.m. attack by a gang of dozens; early reports indicated several officers ? perhaps four or five ? and several attackers were killed. Police didn't immediately confirm a death toll.

The country's leaders have been working for months to reduce election-related tensions, but multiple factors make more vote violence likely. The police said late Sunday that criminals were planning to dress in police uniforms and disrupt voting in some locations.

In addition, intelligence on the Somali-Kenya border indicated Somali militants planned to launch attacks; a secessionist group on the coast threatened ? and perhaps already carried out ? attacks; the tribes of the top two presidential candidates have a long history of tense relations; and 47 new governor races are being held, increasing the chances of electoral problems at the local level.

Perhaps most importantly, Uhuru Kenyatta, one of two top candidates for president, faces charges at the International Criminal Court for orchestrating the 2007-08 postelection violence. If he wins, the U.S. and Europe could scale back relations with Kenya, and Kenyatta may have to spend a significant portion of his presidency at The Hague. Kenyatta's running mate, William Ruto, also faces charges at the ICC.

Long lines began forming early across the nation. In Kibera, Nairobi's largest slum, some 1,000 people stood in several lines at one polling station before daybreak. Voter Arthur Shakwira said he began standing in line at 4 a.m. but left the queue over confusion about which line to stand in. Nearby, Amos Achola said he arrived at the polling station at 2 a.m. and was one of the first to vote.

Kenyatta, a Kikuyu who is the son of Kenya's founding president, faces Raila Odinga, a Luo whose father was the country's first vice president. Polls show the two in a close race, with support for each in the mid-40-percent range. Eight candidates are running for president, making it likely Odinga and Kenyatta will be matched up in an April run-off, when tensions could be even higher.

Most voters in Kibera, like Achola, support Odinga.

"I think he wins but if he doesn't win I'll abide by the outcome," Achola said. "The other guy is also a Kenyan. If Kenyatta wins I'll accept it but I won't like. But I don't want violence."

New technology ? in part to prevent the allegations of rigging that haunted the 2007 vote ? appeared to slow down early voting. At the Mutomo Primary School in Gatundu, where Kenyatta is expected to cast his ballot, voting officials seemed overwhelmed by the finger-print technology. The election worker behind the computer looked nervous and sometimes scratched his head.

The first person to vote, an eldery woman, cast her ballot at 6:25 a.m., 25 minutes after the polls opened.

In Mombasa, police boss Aggrey Adoli said that police were attacked at 2 a.m. by a marauding gang while on patrol. He didn't immediately confirm a death toll but reporters at the scene said police indicated that up to five officers and several attackers were killed in a fight that involved guns and machetes.

A late Sunday attack in the city of Garissa, near the Somali border, killed two people, including a Red Cross paramedic and a driver. Officials said a candidate for parliament had been the target but was not hit.

Garissa County Commissioner Mohamed Ahmed Maalim said Sunday that officials intercepted communications that indicated terror attacks were planned. Maalim said soldiers are patrolling the region to prevent attacks from al-Shabab, the al-Qaida-linked Somali militant group. He said 300 specialized troops known as GSU are patrolling the Dadaab refugee camp, where more than 400,000 Somalis live.

In the weeks leading up to Monday's vote, described by Odinga as the most consequential since independence from the British in 1963, peace activists and clerics have been praying that this time the election is peaceful despite lingering tensions.

Odinga's acrimonious loss to President Mwai Kibaki in 2007 triggered violence that ended only after the international community stepped in. Odinga was named prime minister in a coalition government led by Kibaki, with Kenyatta named deputy prime minister.

Some 99,000 police officers will be on duty during an election in which some 14 million people are expected to vote.
