(PhysOrg.com) — CEATEC Japan, the Tokyo event focused on new devices in electronics and IT, opens this week with lots of pre-buzz circling around a little gadget that keeps smartphones from dying, courtesy of NTT DoCoMo and NEC. Engadget seeded the interest after visiting NTT DoCoMo’s booth to examine an NTT smartphone battery. The charge takes only ten minutes. The battery lives in an external pack. NTT DoCoMo and NEC have developed this prototype as an external lithium ion battery sleeve which is placed on a user’s smartphone. “A pair of amp meters compared the power draw of a standard battery with that of the ultra high speed charger, which pulled 0.55 amps and 5.86 amps, respectively — at least according to the demo equipment on hand at NTT’s CEATEC booth,” wrote Zach Honig of Engadget. The battery sleeve’s AC adapter supports output of up to 6.0 amps, he added. The video report says it should be able to power a phone for at least a few hours.There is no specific information on a targeted release date or the company’s intentions to have the device work with any other phone than the one it works with now, the NEC Medias Android smartphone, available to the Japanese market. NCC DoCoMo’s press release describing its CEATEC showcase only said this: “This special battery jacket for smartphones achieves a full charge in just 10 minutes. A recharging indicator will show how the jacket will charge a smartphone 10~15 times faster than conventional charging devices.”Like other companies at the CEATEC show, NTT DoCoMo is eager to show its innovative edge. The prototype is one of numerous gadgets that the company seeks to publicize here. According to the company release, “Three types of special jackets for smartphones are equipped with sensors that can be customized to measure ultraviolet light and bad breath, gamma radiation and body fat.”As for the new gadget for high-speed battery charging, technology users need little imagination, only hope, to anticipate battery charger solutions to ease the inconvenience of having to wait around for their smart devices to power up. Waiting around for only ten minutes would be an advantage.A frequent complaint generally is that smartphones have come a long way yet battery technologies to support them have not kept pace. Earlier this year, Megan Geuss wrote in PC World: “Battery makers are trying to wring the last bits of capacity out of 15-year-old lithium ion technology, while device and app makers seem to be just waking up to the seriousness of the problem.” © 2011 PhysOrg.com NTT Docomo’s new smartphone features wireless charger Citation: Ten-minute charge makes battery spectacle at CEATEC (2011, October 4) retrieved 18 August 2019 from https://phys.org/news/2011-10-ten-minute-battery-spectacle-ceatec.html Explore further
Citation: Into the breach: Transporting molecular cargo through algal cell walls (2012, August 20) retrieved 18 August 2019 from https://phys.org/news/2012-08-breach-molecular-cargo-algal-cell.html (Phys.org) — Algae constitute a widespread, highly varied group of primarily photosynthetic organisms found in many ecological niches. The roughly estimated 300,000 species range in size and complexity from small to very large, and unicellular to multicellular, respectively. Moreover, their properties are equally diverse in terms of applications, having a potentially unique role in medical, materials, energy, bioremediation, and synthetic biological research. That being said, methods for investigating and making use of algal biology have been slow to emerge. Recently, however, scientists at Stanford University and Lawrence Berkeley National Laboratory have devised a general-purpose molecular technique that allows cargoes of various sizes to be transported through the algal cell wall and membrane, thereby accessing the intracellular algal space.

A significant benefit, Wender adds, was that making non-covalent protein complexes – which often can be quite difficult – proved to be relatively straightforward. “This has value since one needn’t invest in making covalent conjugates – itself often a challenging process,” he adds. “However, showing that the proteins have functional activity was more complex, as both uptake and function needed to be achieved. While technically more demanding, the process worked impressively well. It’s great to be working with such creative and determined coworkers.”Wender also points out that their findings impact several areas of research. “Firstly, in algal research our ability to study and manipulate algae is determined by our ability to introduce molecules into algae that could report back or create change. Some molecules do this on their own, but the vast majority of molecules do not pass through the algal cell wall and membrane.” Mechanical and physical methods – for example, biolistics (gene guns), sonication, electroporation, and glass beads – have been developed to circumvent this limitation. However these are often expensive, encounter reproducibility problems and/or are not readily scaled. “Shooting DNA coated particles into algae is an important technique but it is well quite literally hit-and-miss,” Wender says. “However, we’re now reporting a molecular method in which algae are incubated with a probe connected to a molecular transporter, which enables the resultant conjugate to enter cells, and moreover show that this works for both small molecules and large proteins.” In other words, agents that would otherwise not enter cells are now carried into cells by the molecular transporters. This opens a wide range of chemicals that could be used to study algal function and to use algae in drug discovery, as tools for research including energy research, as agents for bioremediation or as biosensors.Secondly, Wender continues, their findings impact the use of algae as photoautotrophic tools for synthetic biology. “Being able to transform algae allows one to control what they produce and the quantity of what they produce. Algae already produce products of commercial value – and this new technology could be used to enhance those processes.” Of equal imports, he adds, their new technology could be used to induce algae to produce new materials of potential value in research, materials science, and even therapy.Finally, Wender points out that their results will enhance the understanding of biological barriers in the life sciences – specifically, agricultural and medical research. “Biological barriers are of great importance in many areas of science. If a drug, probe or agent does not enter a cell we cannot begin to understand the inner workings of a cell or manipulate it for diagnostic or therapeutic ends. This study now provides a powerful tool to study and manipulate algae.” The cell wall barrier is also found in plants, and so this research has ramifications in agriculture and plant sciences. “We now have a new and molecular way to ferry chemicals across cell walls. We can now communicate with algae.”In terms of planned next steps in their research, Wender concludes, algae represent model organisms for drug discovery, for sensing, for energy research and for bioremediation. “Algae are motile, and therefore can gather and concentrate pollutants. Learning how to control that process is one of many directions with environmental ramifications, and learning how they process drug candidates could be a great way to screen for future therapeutics.” Explore further Stanford University Bergstrom Professor of Chemistry Prof. Paul A. Wender, Lawrence Berkeley National Laboratory scientists Joel M. Hyman, and Bahram Parvin, and Stanford researchers Erika I. Geihe and Brian M. Trantow encountered a series of challenges in designing and implementing their method of variable-scale algal cell molecular transport and delivery. “We reported for the first time in 2000, based on our systematic reverse engineering of the Tat nine-mer, a nonapeptide sequence from the protein HIV Tat, “ Wender tells Phys.org, “that the number and spatial array of guanidinium groups is what allows both the Tat protein and Tat peptide to enter mammalian cells. At the time we coined the term molecular transporters, as we realized from our research that this ability to enter cells was not a function of the peptidic backbone but rather the number of guanidinium groups and their spacing. This led to the design of peptoid transporters, non-peptidic transporters, dendrimers and many other guanidinium-rich transporters capable of carrying molecules into cells,” Wender explains. Much of this earlier work focused on getting transporters through the plasma membrane of mammalian cells. At that time, they also showed that these guanidinium-rich transporters will ferry a variety of cargos including peptides, metals, probes, proteins, and nucleic acids (siRNA) into cells. In addition, these transporters were also shown to transport cargo across other barriers such as the skin. “Algae presented a new challenge as they not only have a membrane barrier but also, for many types of algae, a cell wall,” Wender continues. “Thus, our initial task was simply to see if our lead transporter octaarginine, when attached to a fluorescent tag such as fluorescein, would get through both the cell wall and cell membrane of algae.” While the synthesis of this oligoarginine-fluorescein conjugate follows directly from their previous studies, recording uptake of this conjugate into algae proved to be more difficult than working with mammalian cells – because, Wender exclaims, the algae move! Their solution (which Wender unabashedly describes as clever): make small wells for the algae to dock, preventing their motion during the process of recording images.

More information: Detecting intraannual dietary variability in wild mountain gorillas by stable isotope analysis of feces, PNAS, Published online before print December 10, 2012, doi: 10.1073/pnas.1215782109AbstractWe use stable isotope ratios in feces of wild mountain gorillas (Gorilla beringei) to test the hypothesis that diet shifts within a single year, as measured by dry mass intake, can be recovered. Isotopic separation of staple foods indicates that intraannual changes in the isotopic composition of feces reflect shifts in diet. Fruits are isotopically distinct compared with other staple foods, and peaks in fecal δ13C values are interpreted as periods of increased fruit feeding. Bayesian mixing model results demonstrate that, although the timing of these diet shifts match observational data, the modeled increase in proportional fruit feeding does not capture the full shift. Variation in the isotopic and nutritional composition of gorilla foods is largely independent, highlighting the difficulty for estimating nutritional intake with stable isotopes. Our results demonstrate the potential value of fecal sampling for quantifying short-term, intraindividual dietary variability in primates and other animals with high temporal resolution even when the diet is composed of C3 plants. (Phys.org)—Researchers from several universities in the US have together found that it is possible to follow changes in a wild animal’s diet over a single year period by studying isotopes in feces samples. The team used the technique, as they write in their paper published recently in the journal PNAS, to study the diet of wild mountain gorillas in Uganda. The gorillas in Uganda’s Bwindi Impenetrable National Park in the mountainous southwestern part of the country are difficult to study in the wild. Scientists want to know what they eat over the course of a single year because it would provide valuable information regarding how the animal survives, and perhaps more importantly, how it adapts to environmental changes. Rather than watching every move the gorillas made over an extended period of time, the researchers instead collected fecal samples along with samples of plants and fruits that the gorillas are thought to eat, over a 10 month period during 2002-2003.The samples were brought back to the lab where the researchers subjected them to chemical analysis to reveal the isotopes found in the food that the animals had eaten. Because different foods have different levels of isotopes, the researchers were able to determine which foods had been eaten at which time of the year. They found, for example that the gorillas tended to eat more fruit between February and March and then again between June and July.Prior research had shown that an animal’s diet could be found by studying isotopes in samples of hair, tooth enamel or bones – but that requires capturing animals and testing them, a less then optimal solution. This new research shows that the diet of wild animals can be discerned by simply collecting the droppings they leave behind, which allows for fine tuning such studies by allowing for testing on a more often and regular basis.The researchers noted also that collecting and studying feces samples doesn’t do away with the need for field study however, as the testing for isotopes isn’t precise enough to tell researchers exactly which foods have been consumed – they need a base list to choose from to understand what has actually been eaten. Nor does it offer data on nutritional value.

Fancy places need fancy décor. Right? Wrong. Sometimes, a place can be fancy without going overboard on the décor. Which is what I found interesting about Zing at The Metropolitan Hotel and Spa. Minimalistic chic is how Zing has been designed. The outdoorsy feel comes from the swimming pool and the backyard of the hotel that it overlooks. While this isn’t where you would want to come if you have a romantic lunch or dinner in mind, it is just perfect for lunch with the girlfriends over gossip and cocktails. I would give it a thumbs up for business meetings too. The menu is more cafe than fine dining, even though they have a good selection of champagnes, wines, single malts and scotch. Also Read – ‘Playing Jojo was emotionally exhausting’The food on offer is a global platter — so you find everything from Indian to southeast Asian, Continental and more. In mood for Continental? Order some Fish N Chips and Surf N Turf along with lamb chops. Care for Indonesian or Thai? Dig into Nasi Lemak with Bamboo steamed vegetables and Phad Thai. There is Italian too if you so fancy. The star on the menu though, is German. The classic German dish, Curry Wurst, has thankfully not given an Indian makeover here and retains its juicy nature. German sausages, a dash of tomato to add a zing to it and potato salad, this one kind of takes the cake if you decide to stick to Continental. Pair it with a Jack and Coke or Jim Beam — it is filling enough to become one whole meal. Also Read – Leslie doing new comedy special with NetflixNot fond of whiskey? Grab a Qutub Chinar (tall vodka, rum with rose and lemon) or a Sharabi Gola (gin and sweet vermouth with orange juice) from the bar. They are just as nice. The selection of tea and coffee is also quite interesting. Non vegetarians will relish this place because most of the items on the menu are all about meat. However, leaf eaters can try out the Khaw Suey (recipe left) or Cottege Cheese Brochettes among others. I settled for some Butterfly prawns which are batter fried and served with sweet chilli and garlic sauce with a chilled beer. It was fried yes, (I wasn’t technically thinking of diet) but not oily enough to make it unhealthy. The Zing Club (available in both vegetarian and non vegetarian versions) is quite a meal in itself too. Meat eaters can choose between chicken, turkey and eggs. The desserts section has the usual suspects like brownies and cheesecakes, with a twist (imagine Star anise stewed cherry cheesecake and Kahlua flavoured opera with truffle and butter cream). Be careful of the ice cream though, it is served so chilled that your teeth would freeze. But go to Zing if you care for a simple, fuss-free meal.DETAILAt: Zing, The Metropolitan Hotel and Spa, Bangla Sahib Road Timings: All Day Phone: 4250 0200 Meal for Two: Rs 3,500 (Approx Without Alcohol)

Kolkata: Chief Minister Mamata Banerjee on Tuesday said lateral entries might “dilute the sensitivity” attached to the functioning of the government and the issue needed a “wider debate” among the various stakeholders before it was implemented.She stressed on “…discussion with different stakeholders, including representatives of the All India Services/Central Services,” before its implementation as the officials of joint secretary level is usually involved in framing policies. Also Read – Heavy rain hits traffic, flightsIt may be mentioned that as per the notification of the Department of Personnel Training, individuals working at comparable levels in the private sector companies, consultancy organisations, international/multinational organisations, any state or Union Territory government or working at comparable levels in Public Sector Undertakings, autonomous bodies and universities can apply for three to five years’ contract basis recruitment in 10 senior level posts in departments including Commerce and Civil Aviation Revenue and Economic Affairs.

In my view, there is no objection if talented persons join the Central Government to improve its professional competence and efficiency. But I have few concerns about the issue involving various implications.” Stating the significance of the joint secretary level officials and the need to recruits officers through the UPSC, she stated in her tweet: “The officers from All India Services/Central Services presently hold positions of Joint Secretary and equivalent levels in the Government of India. These officers are inducted in government services through transparent recruitment processes by Constitutional bodies like the UPSC. The officers are expected to be politically neutral while discharging their duties. Any shift from such standard will not be good for the nation. Presently, the officers of All India/Central Services have been working in the government with sincerity and accountability and maintaining secrecy, where the paramount interest of the nation remains supreme.” Sharply reacting to the decision of lateral entry, Banerjee mentioned in her tweet: “In view of it, I feel that any deviation from the system, particularly by inducting professionals from non-governmental sector, notwithstanding their talent may dilute the sensitivity attached to the functioning of the government. Therefore, it is necessary to have wider debate and discussion with different stakeholders, including representatives of the All India Services/Central Services, before implementing the proposed induction of lateral entries into senior positions of the government. I thought of sharing this with all of you as it is a matter of concern.”
