<span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><span style="background-color: white; color: #333333; line-height: 22px;">Having revealed its </span>original Hoverbike design<span style="background-color: white; color: #333333; line-height: 22px;"> back in 2011, Malloy Aeronautics has been hard at work developing its ambitious, science fiction-inspired vehicle. The team has made some significant changes in the last few years, moving from a dual rotor to quad rotor design while adding some serious stability credentials in the process. Chris Malloy has now launched a crowdfunding campaign on Kickstarter where backers are being offered a working one third scale version of the second-generation Hoverbike, while giving the team a helping hand in the development of the eventual, manned vehicle.</span></span><br />
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The hoverbike has been a staple of science fiction for decades, but it’s only in recent years that the concept has started to take tangible steps into reality. The team’s original Hoverbike design, revealed back in 2011, boasted some impressive stats, including the ability to theoretically reach speeds of up to 150 knots (278 km/h or 173 mph) and altitudes of 10,000 ft (3,048 m) and beyond.</span></div>
<div class="article_img" style="background-color: white; color: #333333; height: 298px; line-height: 22px; margin: 0px auto 5px; padding: 0px; width: 530px;">
<a href="http://www.gizmag.com/hoverbike-kickstarter-drone/33057/pictures#1" style="background-color: transparent; color: #1e8dd7; text-decoration: none;" target="_blank"><span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><img alt="The quadcopter drone version of the Hoverbike can travel at speeds of up to 45 mph" src="http://images.gizmag.com/inline/malloy-hoverbike-kickstarter-0.jpg" style="border: 0px; vertical-align: bottom;" width="530" /></span></a></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">With its new design, the one third scale drone version of the vehicle is impressively stable and is even able to carry a glass of water without spilling. The scaled down version of the vehicle, which acts as a proof of concept for the full-sized Hoverbike, packs a 3DR Pixhawk flight controller and is capable of following a pre-determined flight path, following the pilot, and can even perform automatic take-off and landing maneuvers.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The drone is 1,155 mm (45.5 in) in length, constructed from aircraft grade aluminum, carbon composite and polyurethane, and capable of carrying a recommended payload of 1.5 kg (3.3 lb). The quadcopter itself weighs in at 2.2 kg (4.85 lbs), and can travel at speeds of up to 45 mph (72 km/h). Its flight time is determined by the weight of its payload.</span></div>
<div class="article_img" style="background-color: white; color: #333333; height: 429px; line-height: 22px; margin: 0px auto 5px; padding: 0px; width: 530px;">
<a href="http://www.gizmag.com/hoverbike-kickstarter-drone/33057/pictures#2" style="background-color: transparent; color: #1e8dd7; text-decoration: none;" target="_blank"><span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><img alt="The Hoverbike can be folded to a third of its full length" src="http://images.gizmag.com/inline/malloy-hoverbike-kickstarter-1.png" style="border: 0px; vertical-align: bottom;" width="530" /></span></a></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The scaled down version of the Hoverbike also has an advantage over other consumer quadcopters in that it folds down to a more manageable 590 mm (23.2 in) length. You can even purchase a purpose designed backpack from Malloy Aeronautics for transportation. Pledges for the fully functional drone start at £715 (US$1,219), with shipping expected to start three to four months following the conclusion of a successful Kickstarter project.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">One last thing that makes the miniature hoverbike an even more appealing prospect is the so-called Cyborg Buster one third scale human model that is available as a CAD design and ready for home 3D printing. The semi-articulated figure is designed to mimic a human pilot, and there’s even a purpose-designed space in the head for a Go-Pro camera.</span></div>
<div class="article_img" style="background-color: white; color: #333333; height: 528px; line-height: 22px; margin: 0px auto 5px; padding: 0px; width: 526px;">
<a href="http://www.gizmag.com/hoverbike-kickstarter-drone/33057/pictures#6" style="background-color: transparent; color: #1e8dd7; text-decoration: none;" target="_blank"><span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><img alt="Kickstarter backers will be able to 3D print their own Cyborg Buster pilot" src="http://images.gizmag.com/inline/malloy-hoverbike-kickstarter-6.png" style="border: 0px; vertical-align: bottom;" width="526" /></span></a></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">While the tangible reward of your very own Hoverbike quadcopter might be enough to make you shell out and support the crowdfunding campaign, the final goal of the project is a little grander. After years of development, the team at Malloy Aeronautics arrived at the current quad rotor design and is now working towards the construction of a final engineering prototype for submission to aviation certification authorities. The team plans to use the funds provided by Kickstarter backers to make this a reality and will continue work until the eventual manned Hoverbike is available for sale.</span></div>
<div style="background-color: white; clear: both; color: #333333; line-height: 22px; margin-bottom: 10px; padding: 0px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Once the full size vehicle is operational, the team envisages that it will be used for more than just recreation, highlighting uses including cattle mustering, cargo insertion (up to 120 kg/265 lb) and perhaps most notably, search and rescue operations. The fact that the vehicle can be folded down to a third of its length makes it easy to transport, and its precision controls should make it ideal for dealing with difficult terrain such as that associated with ski and mountain rescues.</span></div>

<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Hate unlocking your Android smartphone so much that even Face Unlock or Skip feels like too much of a hassle? Motorola just came to your rescue. The company has partnered with VivaLnk to launch the previously teased <a href="http://motorola-blog.blogspot.ca/2014/07/-unlock-your-moto-x-with-a-digital-tattoo.html" style="color: #3399cc; text-decoration: none;" target="_blank">Digital Tattoo</a>, an NFC-based skin tag that unlocks your phone (currently limited to the Moto X) with a quick tap. The tattoo can stay on your body for up to five days, and it should survive abuses like showers and sweat-laden runs. It's a clever approach that might be appealing if you're fed up with PIN codes and patterns, although the back-of-a-napkin math suggests that you're paying a lot just to save a couple of seconds when checking your email. VivaLnk is asking $10 for packs of 10 tattoos, or enough to last 50 days -- you'll have to spend $80 to get through a whole year. It could be useful for those busy days when you're constantly waking up your handset, but you might be better off rolling that money into a Moto 360 or your next big phone upgrade.</span></div>

<span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><span style="background-color: white; color: #333333; line-height: 25px;">Scientists from Polytechnique Montreal and Gorilla Glass manufacturer Corning have developed a new display sensor for smartphones that can allow a user to check his/her blood sugar levels (if diabetic), assess body temperature, and even analyze DNA. The sensors can be embedded within the smartphone's display. It can work with platforms such as Apple's HomeKit in order to provide more information about one's health.</span><br style="background-color: white; color: #333333; line-height: 25px;" /><br style="background-color: white; color: #333333; line-height: 25px;" /><span style="background-color: white; color: #333333; line-height: 25px;">Also, the researchers have developed their first laser-written light-guiding systems that could initiate these advancements. The systems can shot lasers into glass to create pathways that transmit data in the form of small beams of light. On the other hand, the waveguides act as a tunnel that channel light.</span><br style="background-color: white; color: #333333; line-height: 25px;" /><br style="background-color: white; color: #333333; line-height: 25px;" /><span style="background-color: white; color: #333333; line-height: 25px;">The scientist said that the approach created by the team is nearly 10 times better at minimizing loss compared to previous ones made with lasers. These sensors could be embedded in biomedical sensors into tablets and window pc's as well. They also added that the technology could also be used to add security to mobile devices and monitor carbon-monoxide levels in the air as well.</span><br style="background-color: white; color: #333333; line-height: 25px;" /><br style="background-color: white; color: #333333; line-height: 25px;" /><span style="background-color: white; color: #333333; line-height: 25px;">Paper co-author Raman Kashyap, a professor of electrical engineering and engineering physics at Polytechnique Montreal, said in a statement, "We're opening the Pandora's box at the moment."

Put Down Your Syringe, Nanoparticles May One Day Deliver Drugs

<div dir="ltr" style="text-align: left;" trbidi="on">
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;"><img alt="MIT, drugs, nanoparticles, cell, biology" src="http://www.engineering.com/Portals/0/BlogFiles/DesignerEdge/0714/MITGoldDrug.jpg" /></span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">A special class of tiny gold particles can easily slip through cell membranes, making them good candidates to deliver drugs directly to target cells.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">A new study from MIT materials scientists reveals that these nanoparticles enter cells by taking advantage of a route normally used in vesicle-vesicle fusion, a crucial process that allows signal transmission between neurons. In the July 21 issue of<em>Nature Communications</em>, the researchers describe in detail the mechanism by which these nanoparticles are able to fuse with a membrane.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The findings suggest possible strategies for designing nanoparticles — made from gold or other materials — that could get into cells even more easily.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">“We’ve identified a type of mechanism that might be more prevalent than is currently known,” says Reid Van Lehn, an MIT graduate student in materials science and engineering and one of the paper’s lead authors. “By identifying this pathway for the first time it also suggests not only how to engineer this particular class of nanoparticles, but that this pathway might be active in other systems as well.”</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The paper’s other lead author is Maria Ricci of École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. The research team, led by Alfredo Alexander-Katz, an associate professor of materials science and engineering, and Francesco Stellacci from EPFL, also included scientists from the Carlos Besta Institute of Neurology in Italy and Durham University in the United Kingdom.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Most nanoparticles enter cells through endocytosis, a process that traps the particles in intracellular compartments, which can damage the cell membrane and cause cell contents to leak out. However, in 2008, Stellacci, who was then at MIT, and Darrell Irvine, a professor of materials science and engineering and of biological engineering, found that a special class of gold nanoparticles coated with a mix of molecules could enter cells without any disruption.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">“Why this was happening, or how this was happening, was a complete mystery,” Van Lehn says.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Last year, Alexander-Katz, Van Lehn, Stellacci, and others discovered that the particles were somehow <a href="http://newsoffice.mit.edu/2013/the-gold-standard-for-cell-penetration-0823" style="color: #003366; text-decoration: none;">fusing with cell membranes</a> and being absorbed into the cells. In their new study, they created detailed atomistic simulations to model how this happens, and performed experiments that confirmed the model’s predictions.</span></div>

<div style="background-color: white; line-height: 26px;">
<strong><span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Stealth Entry</span></strong></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Gold nanoparticles used for drug delivery are usually coated with a thin layer of molecules that help tune their chemical properties. Some of these molecules, or ligands, are negatively charged and hydrophilic, while the rest are hydrophobic. The researchers found that the particles’ ability to enter cells depends on interactions between hydrophobic ligands and lipids found in the cell membrane.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Cell membranes consist of a double layer of phospholipid molecules, which have hydrophobic lipid tails and hydrophilic heads. The lipid tails face in toward each other, while the hydrophilic heads face out.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">In their computer simulations, the researchers first created what they call a “perfect bilayer,” in which all of the lipid tails stay in place within the membrane. Under these conditions, the researchers found that the gold nanoparticles could not fuse with the cell membrane.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">However, if the model membrane includes a “defect” — an opening through which lipid tails can slip out — nanoparticles begin to enter the membrane. When these lipid protrusions occur, the lipids and particles cling to each other because they are both hydrophobic, and the particles are engulfed by the membrane without damaging it.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">In real cell membranes, these protrusions occur randomly, especially near sites where proteins are embedded in the membrane. They also occur more often in curved sections of membrane, because it’s harder for the hydrophilic heads to fully cover a curved area than a flat one, leaving gaps for the lipid tails to protrude.</span></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">“It’s a packing problem,” Alexander-Katz says. “There’s open space where tails can come out, and there will be water contact. It just makes it 100 times more probable to have one of these protrusions come out in highly curved regions of the membrane.”</span></div>
<div style="background-color: white; line-height: 26px;">
<strong><span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Mimicking Nature</span></strong></div>
<div style="background-color: white; line-height: 26px;">
<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">This phenomenon appears to mimic a process that occurs naturally in cells — the fusion of vesicles with the cell membrane. Vesicles are small spheres of membrane-like material that carry cargo such as neurotransmitters or hormones.</span></div>

<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">The similarity between absorption of vesicles and nanoparticle entry suggests that cells where a lot of vesicle fusion naturally occurs could be good targets for drug delivery by gold nanoparticles. The researchers plan to further analyze how the composition of the membranes and the proteins embedded in them influence the absorption process in different cell types. “We want to really understand all the constraints and determine how we can best design nanoparticles to target particular cell types, or regions of a cell,” Van Lehn says.</span></div>

<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">“One could use the results from this paper to think about how to leverage these findings into improved nanoparticle delivery vehicles — for instance, perhaps new surface ligands for nanoparticles could be engineered to have improved affinity for both surface groups and lipid tails,” says Catherine Murphy, a professor of chemistry at the University of Illinois at Urbana-Champaign who was not involved in the study.</span></div>

Amazon's new games show what only the Fire Phone can do

<span style="font-family: Georgia, Times New Roman, serif; font-size: large;">Looks like Amazon plans to take advantage of the Fire phone's head-tracking tech at every turn, so it put its Game Studio to work developing two new titles especially for the device. The first one called <em>Saber's Edge</em> is a strategic pirate puzzle game, while the other, called<em>To-Fu Fury</em>, is a puzzle platformer (think <em>'Splosion Man</em>) that stars a tofu martial artist. They sound like funny, typical mobile games, other than the fact that they support the Fire phone's "Dynamic Perspective" feature that tracks the movements of a user's head. Sadly, you can't exactly control the games by moving your noggin (that might sound silly, but at least that'll make the games truly unique), but you can peek around the corners to see hidden obstacles or bonuses. Of course, you can always just tilt the phone if you don't want to look silly in public. If you don't mind the games' limited support for the feature, you can grab em for $1.99 each -- but only if you're also getting the Fire Phone, which starts shipping this week.</span></div>
