Is there anything that Google didn’t announce at the keynote of its Google I/O developers conference Wednesday morning? Google just unleashed a fury of new features for all of its properties today at the Google I/O keynote. We saw new developer features for Android, a variety of tools and functions for the Chrome browser and OS, a boatload of pictures and communication features for Google+ (along with a redesign), the expansion of Google’s Knowledge Graph, new music, new maps for mobile and more. It is enough to make your head spin just thinking about how much stuff Google is doing these days.But there were things we thought we might see from the I/O keynote that did not show up.A New Version Of AndroidWe were almost certain that Google would at least provide a small new update to Android. Whether it was Android 4.3 Jelly Bean or Android 5.0 Key Lime Pie (or any mix thereof), how could Google go through an entire I/O and not update its most important platform? Android has seen 900 million activations. Google Play Android apps have been downloaded 48 billion times. Android has become a mature, stable platform. Google does not really need to push out new Android updates at a breakneck pace the way it has done in the past. Today’s Android news seemed more about helping the developer ecosystem and community catch up with the platform, to make their lives easier and make them more money. What it Takes to Build a Highly Secure FinTech … Tags:#Android#Chrome OS#Google IO13#io13#Nexus Why IoT Apps are Eating Device Interfaces Hardly Any New HardwareGoogle announced a new version of the Chrome Pixel for Chrome OS and a “Nexus” version of the Samsung Galaxy S4. We were not really expecting much in terms of hardware from I/O this year, but compared to 2012, the new gadgets were really sparse. Google did not announce a new Nexus device (because there was no new version of Android). That means no new smartphone or tablet, no updates to Google Glass, no set top box for your television and no smartwatch. No Major Upgrade to Chrome OSChrome was a major topic during the I/O keynote. Google featured the mobile Web, the Chrome Pixel and demoed HTML5 and responsive design features.Yet Google did not do anything groundbreaking with Chrome OS. Google’s desktop operating system never really seems to take major jumps – instead seeing a constant stream of new updates and features. Chrome may not seem like it is evolving much on a day-to-day or month-to-month basis, but look back a year and you will notice that it is significantly different today than it was at last year’s I/O. Google Glass Makes No NewsGoogle co-founder Sergey Brin did not make an appearance at all during the I/O keynote. Hence, neither did his pet project, Google Glass. After all the announcements on Android, Chrome, Search, Maps, Google+ and everything, Google’s most-hyped new product these days got no mention.Larry Page addressed a question from Robert Scoble on Glass at the end of the keynote, but that was about it. It seems that Glass is not a substantial part of Google’s future. It is cool, fun, geeky, but kind of a side show.Note, lead image by Nick Statt was altered to create an empty podium.

Whenever Robin Washington, a project manager with Clark County Public Works, is asked why the improvements on Northeast 119th Street are taking so long to build, she likens it to another large undertaking.“I ask people, ‘How do you eat an elephant?’” she said. “One bite at a time.”Now the county is finishing one bite and is starting on another as it continues its multiyear project to upgrade Northeast 119th Street from a two-lane country road with no sidewalks or bicycle lanes to an arterial intended to accommodate growing suburbanization.Washington said that McDonald Excavating, a Washougal-based contractor, is wrapping up work on a stretch of Northeast 119th Street between Northeast 50th Avenue and Northeast 72nd Avenue. Work between 72nd and Northeast 87th Avenue was completed last year, and now contractor Rotschy is launching a project from 87th to Northeast 112th Avenue. The county awarded the Vancouver-based company an $11.18 million contract, according to a news release.Clearing the wayWashington said that crews will be out clearing the roadsides and cutting trees in anticipation of upgrades. She also said that utilities will also have to clear pipes and poles that are in the way. She said the project will last two seasons and expects it to be finished in late 2019, according to a county news release.According to the news release, more than $50 million will be spent on the corridor. The county has been awarded two grants to help pay for construction: a $4 million state Urban Arterial Program grant through the Washington State Transportation Improvement Board and a $3.1 million federal Surface Transportation Program grant through the Southwest Washington Regional Transportation Council.
Journal information: Science © 2013 Phys.org In order for cells in living creatures to function properly, they must have a means for allowing water to pass through from the outside world into their inner structure—through their membranes. This is how they receive nutrients. At the same time, the water that passes through the membrane must be filtered to keep unwanted material from being carried through with the water. How this happens has been somewhat of a mystery because the channels that carry the water (aquporins) are so small—traditional methods only allow for snapshot views. Progress was made a decade ago, however, when a team of researchers developed a technique that allowed for viewing the process by which potassium ions are transported through potassium channels. In this new effort. the joint American-Swedish team took a similar approach to help them capture the process by which Pichia pastoris yeast is transported through an aquaporin 1 protein.The technique involved capturing the process as it happened at ultra-high resolution—in this case just 0.88 Angstroms. This resolution allowed the researchers to see that the process is very similar to the one found by the team that captured the movement of potassium ions. They found that the way hydrogen bonds were shaped prevented protons from passing through the cell membrane along with the water that carried them. Of particular note, they found that two distinct structures, the NPA-signature motif and the selectivity filter caused water molecules to be oriented in just the right fashion to facilitate the passage of the molecules through the pores in the channel while stopping the unwanted protons.The technique the team developed marks a record for high-resolution captures of cell membrane processes, and paves the way for other research efforts looking to determine how water carrying other unwanted material is filtered by channels in cell membranes.

© 2014 Phys.org Two-dimensional sheets of electronic materials show promise for practical nanoelectronics Journal information: Nature Materials While carbon nanotubes have dominated the headlines in the search for the basis of the next generation of computer chips, scientists have been making inroads using other materials as well—one in particular, MoS2, has shown promise. It’s actually been used to create working electronic devices. Unfortunately, its use in mass producible devices has been limited by the same constraint as that found with carbon nanotubes—the resistance that occurs when attempting to connect the semiconductor to other electronics. The problem comes about because the sheets are so thin, attempting to attach wires has been problematic and research into doping methods has not gone well. In this new effort, the researchers have found a way to change the phase of a sheet of MoS2 from a semiconductor, to metallic, i.e. a fully conducting contact.The idea is that if a tiny section of a MoS2 sheet can be phase shifted to a metallic state, then wires could very easily be connected to it, and that’s exactly what they team has done—they developed a process they call lithiation which modifies the MoS2 to the metallic phase, by exposing the material to n-butyl lithium. To make sure it really works, they successfully built several field effect transistors using the modified sheets.There are still some problems however, the team is having trouble finding a way to accurately phase shift just the part of a sheet they’re after, and because MoS2 is metastable, it tends to shift back to its purely semiconductor phase under certain conditions, and the researchers aren’t sure just yet what exactly those conditions are. The team is working on these issues, of course—one possible solution may be in producing MoS2 differently—creating flakes using exfoliation, perhaps or chemical vapor deposition. More information: Phase-engineered low-resistance contacts for ultrathin MoS2 transistors, Nature Materials (2014) DOI: 10.1038/nmat4080AbstractUltrathin molybdenum disulphide (MoS2) has emerged as an interesting layered semiconductor because of its finite energy bandgap and the absence of dangling bonds. However, metals deposited on the semiconducting 2H phase usually form high-resistance (0.7 kΩ μm–10 kΩ μm) contacts, leading to Schottky-limited transport. In this study, we demonstrate that the metallic 1T phase of MoS2 can be locally induced on semiconducting 2H phase nanosheets, thus decreasing contact resistances to 200–300 Ω μm at zero gate bias. Field-effect transistors (FETs) with 1T phase electrodes fabricated and tested in air exhibit mobility values of ~50 cm2 V−1 s−1, subthreshold swing values below 100 mV per decade, on/off ratios of >107, drive currents approaching ~100 μA μm−1, and excellent current saturation. The deposition of different metals has limited influence on the FET performance, suggesting that the 1T/2H interface controls carrier injection into the channel. An increased reproducibility of the electrical characteristics is also obtained with our strategy based on phase engineering of MoS2. (Phys.org) —A team of researchers with members from Rutgers University and Los Alamos National Laboratory has found a way to get around the problem of metals forming high-resistance when deposited on 2H phase molybdenum disulphide (MoS2). In their paper published in the journal Nature Materials, the team describes how they came up with a process for inducing 2H phase nanosheets to the metallic 1T phase, thereby reducing contact resistance.
