(PhysOrg.com) — ASUS announced in May it would be producing two Eee Pad tablets, a 12-inch version running Windows 7 Home Premium and a 10-inch with the Windows Embedded Compact 7 operating system. It now seems likely the smaller tablet will use Google’s Linux-based mobile operating system Android instead. ASUS Eee Pad EP101TC This document is subject to copyright.

Eee Pad: AsusTek unveils Windows 7 tablet computer © 2010 PhysOrg.com Android is growing in popularity for smartphones, and so it makes sense for ASUS to adopt an operating system for its tablet that will be familiar to users, and according to Netbook News, this is precisely what ASUS is planning.The version of Android that will be used on the tablet is unclear as yet. The prototype is running Android 2.2 (Froyo), but it seems likely ASUS will wait for version 3.0 (Gingerbread) for use on the production units, which are expected to be released next January at the earliest.The smaller ARM-based Eee Pad tablet, the Eee Pad EP101TC, was demonstrated in June year at Computex 2010 in Taipei, and at that time was running Windows Embedded Compact 7.ASUS has been a close partner of Microsoft for a long time, but in February announced its Android-based Nuvifone A50, developed in partnership with Garmin.

Booth, et al., Nature 468, 959–963 (16 December 2010) doi:10.1038/nature09560 The researchers, led by Lauren N. Booth of the University of California, San Francisco, carried out a series of experiments on three species of yeast: the baker’s yeast (Saccharomyces cerevisiae), dairy yeast (Kluyveromyces lactis) and human pathogen yeast (Candida albicans). All three species have three cell types: the haploids a and α, both of which carry a single set of chromosomes, and the product of their mating, the diploid a/α. They also produce haploid spores which are formed when the diploid divides.The a and α “sexes” mate by fusing together and combining the two sets of chromosomes to form the diploid cell type, which is externally virtually identical to the haploids. In this condition all the mating genes are suppressed and it no longer secretes mating factors, which are secreted constantly in the haploid cells.Each of the cell types has specific genes controlled by specific proteins. In the a cells the genes express a factor “MATa1,” and the equivalent in the α cells is MATα2. In the diploid the factors combine to form a complex a1/α2 and this blocks the expression of the four genes involved in mating and the genes specific to the a and α cell types. The new research has discovered that the dairy yeast has evolved a different form of regulation.In S. cerevisiae diploids the genes specific to the a and α cell types are regulated by the a1/α2 complex, which binds to the DNA near the genes it shuts down. Among the proteins expressed by the genes is an intermediate regulatory protein called RME1. In C. albicans the process is the same but RME1 is not present. In K. lactis RME1 is present and is shut down by the a1/α2 complex, but in this yeast RME1 is the only gene regulated by the complex, and it is RME1 that regulates the expression of the other genes.The differences in regulation of gene expression might have little effect since regulation of the genes in each case depends on the presence of the a1/α2 complex. RME1 is not just regulated by the complex, however, and is also regulated in response to levels of nutrients and is activated in starvation conditions. This means that in all three yeast species the “decision” to mate depends on there being haploids of the opposite type present and secreting the a or α mating factors, but in K. lactis the nutrient levels also have an influence, so that in starvation conditions mating is more likely. Mating is a necessary step in the production of spores, which can ensure the yeast’s survival in hard times.The researchers said a reorganization in a relatively recent ancestor K. lactis produced the indirect suppression of the mating genes by RME1. The overall logic of haploid specific genes active in the a and α cells and off in the diploid is preserved, but the “rewiring” integrated nutritional signals into the mating decision.The paper is published in the journal Nature.
Schwassmann-Wachmann3 Comet: Fragment B photographed during its passing in 2006. We can observe up to 73 fragments. This photo is from APOD (Astronomy Picture of the Day) (Internet 3). Credit: NASA, ESA, H. Weaver (JHU/APL), M. Mutchler and Z. Levay (STScl) Binilla wrote down his observations at the time and took some photographs of what he saw, but never really tried to explain what the objects were. Three years later the French astronomy journal L’Astronomie published the photos but deemed them likely high flying birds or bugs on the camera lens.Now Manterola and his colleagues suggest that there is sufficient evidence to at least consider the possibility that the objects Bonilla saw were comet fragments. First of all they say, Bonilla wrote down everything about the sighting; where in the sky the objects appeared, how many fragments he counted (447) over the two days that he could see them, the type of camera he used and the photography techniques, etc. And perhaps most importantly, the time it took for a single fragment to cross the sun, because it’s that number that allowed the modern researchers to calculate their distance from Earth, which they suggest would have been somewhere near just 8000 kilometers. Also, because of Bonilla’s precision in recording the events, it seems doubtful that he would have overlooked bugs on his lens, or the possibility of the objects being birds, etc.The unfortunate thing in all this is that no one else reported seeing the objects that Bonilla saw, and there was no associated meteor shower as would be expected if a comet fell apart so close to Earth. Manterola and his team say that this could be because of the parallax effect, which happens when an object is so close, only those closest to it can see it. They also note that because of the apparent position of the objects, they would have been observable only from areas in roughly the same latitude, which would have included parts of Africa and Northern India and south-east Asia; places where no one was looking at the sun through a telescope.Others clearly are skeptical, for obvious reasons. But that may or may not matter because if the objects were in fact comet fragments, it appears we came pretty close to being wiped out. The researchers suggest that many of the fragments would have been on the order of the size of the one that struck Siberia back in 1908, destroying everything for miles around. If we’d been hit with hundreds or thousands of such fragments at the same time, it might have knocked the life out of our planet, literally. This document is subject to copyright.

ESA’s New Camera Follows Disintegration of 73P/Schwassmann-Wachmann 3 Comet © 2011 PhysOrg.com Explore further More information: Interpretation of the observations made in 1883 in Zacatecas (Mexico): A fragmented Comet that nearly hits the Earth, arXiv:1110.2798v1 [astro-ph.EP] arxiv.org/abs/1110.2798AbstractIn 1883, on the 12th and 13th of August, Mexican astronomer Jose A. y Bonilla observed several objects passing in front of the solar disk. In 1886 in the L’Astronomie magazine, he reported his observations without providing a hypothesis explaining the registered phenomena. Our objective in this work is to interpret, with current knowledge, what he observed in Zacatecas. Our working hypothesis is that what Bonilla observed in 1883 was a highly fragmented comet, in an approach almost flush to the Earth’s surface. The fragmentation of the comet’s nucleus is a phenomenon known since the XIX century. Using the results reported by Bonilla, we can estimate the distance at which the objects approach to the Earth’s surface, their size, their mass and total mass of the comet before fragmentation. According to our calculations, the distance at which the objects passed over the Earth’s surface, was between 538 km and 8,062 km, the width of the objects was between 46 m and 795 m and its length between 68 m and 1,022 m, the object’s mass was between 5.58e8 kg and 2.5e12 kg. Finally, the mass of the original comet, before fragmentation, was between 1.83e12 and 8.19e15 kg, i.e., between 2e-3 and 8.19 times the mass of Halley Comet.via TechnologyReview, Discover Citation: Mexican astronomers suggest Bonilla sighting might have been a very close comet breaking up (2011, October 19) retrieved 18 August 2019 from https://phys.org/news/2011-10-mexican-astronomers-bonilla-sighting-comet.html (PhysOrg.com) — Mexican astronomers Hector Javier Durand Manterola, Maria de la Paz Ramos Lara, and Guadalupe Cordero working out of National Autonomous University of Mexico in Mexico City, have uploaded a paper onto the prepress server arXiv, suggesting that objects Mexican astronomer José Bonilla recorded in 1883 passing in front of the sun and surrounded by a hazy mist, were in fact fragments of a comet as it came apart very near the earth.

Credit: Ying Chen (Phys.org) —A team of researchers working in Taiwan has found that certain types of diving beetles have a mechanical advantage over other less evolved types of diving beetles. In their paper published in Journal of the Royal Society Interface, the team describes how they compared the suction-cup type bristle gripper mechanisms used by males of one type of beetle to latch onto females, with the less evolved spatula type gripper and found the former to be a much better approach than the latter. To mate, male diving beetles use specialized hairs or bristles on their bodies to latch onto a part of the forewing of the female. Latching on is important because the female moves around a lot, making copulation difficult. In this study, the research team looked to compare the latching abilities of four types of diving beetles—three that have what are described as suction-cup shaped bristles and a fourth which have what are believed to be older, less evolved spatula shaped bristles.Studying the gripping techniques of diving beetles helps researchers understand the complex mating behavior of the beetles—prior research has shown that the females appear to be evolving in a way that makes it more difficult for males to latch on, forcing the males to develop better mechanisms.To find out which type of mechanical mechanism is superior, the researchers clipped samples from both types of beetles and allowed both to latch onto glass cover slips in their lab. They then used a scale to measure vertical suction strength and sensors to measure shearing force. In so doing they found the two approaches yielded approximately the same suction force. When factoring for body size however, the suction-cup mechanism proved to be the superior gripper—it also proved to be better at resisting shearing forces, which likely is just as important, as the females tend to twist and turn at times during mating, possibly as a means of warding off weaker suitors.

It also provides new ideas for engineers working on the development of underwater attachment devices. © 2014 Phys.org More information: Paper: rsif.royalsocietypublishing.or … .1098/rsif.2014.0273 Play Attachment-detachment process of a circular seta from male H. pacificus at a preload of 0.45 mN and pull-off velocity of 75 µm/s (~0.25 seta length per second, LST/s).

Whenever calamity strikes — be it natural or man-made — children are the first ones to suffer. But then again, it doesn’t take a calamity to make children traumatic, a broken family has just the same effect. Advocating children’s right to family is something Butterflies has been doing for ages now. For years, they have been campaigning against the need to eliminate unnecessary institutionalisation of vulnerable children. The family has been recognised as the natural setting for all children by the proposed National Policy for Children 2012, in spite of such legislations and policies we regularly come across institutions set up under the garb of hostels and educational institutions who offer their services to children from poor or low income groups, depriving them of a family life. Also Read – ‘Playing Jojo was emotionally exhausting’ This was the focus of the Gerry Pinto Memorial Lecture Series — First Call for Children. This year, the lectures (held at the India International Centre on Wednesday) dealt with the issue of a child’s right to family. The lecture was chaired by Vasanti Rama of FORCES; Rajni Palriwal, Department of Sociology, Delhi University; Bino Thomas, Head of department, Social work, Christ University, Benguluru and Rita Panicker, Director of Butterflies. Palriwal delivered the key note address. Also Read – Leslie doing new comedy special with Netflix Panicker opened the lecture and spoke of a child’s right to a family and how the two key institutions — family and school — have undergone a change in the last three decades with poverty pushing children to work, forcing many to even migrate. The relationship between poverty and forced institutionalisation though is not very linear, researches conducted by Butterflies have shown children across socio-cultural backgrounds have considered families to be a safety net and prefer living with families. Thomas validated what Panicker said. He said that parenting is no longer just common sense and it was now becoming more of a science and art. Interactions with children in his pre-clinical practice he was told by the children that they want to be parent friendly and parents told him that they would not want to pass on the wounds of their childhood to their children. Children are found to be carriers of family dysfunction and most often behaviour changes are needed with parenting and not with the children. Lack of time, inability to prioritise, generation and communication gap along with a lot of other practical difficulties are some of the reasons he listed as some issues which eventually leads into problem families. Palriwala spoke of extremely dysfunctional families, families with abject poverty, families with illness, neglect, abusive. The state also does not give necessary support to children in this age group and does not figure in any rights, education or health discourse.
