Google Releases DIY Android App Inventor w Video

first_img Explore further Google App Inventor also has blocks for doing ‘programming-like’ things as well as blocks to store information, blocks for repeating actions, and blocks to perform actions under certain conditions. (PhysOrg.com) — Google has announced a new software development program that lets anyone develop an application for Android devices; it’s called the App Inventor for Android. Google says the software is intended to allow any smartphone user develop Android applications without having any prior knowledge of programming languages. Since Google App Inventor provides access to GPS-location sensor, you can build location apps to determine where you are. You can build a useful app that will show you where you parked your car; never forget where you’re car is parked anymore.According to DailyTech, the New York Times states that Harold Abelson is the Google project leader. Harold Abelson is a computer scientist from MIT on sabbatical at Google. Abelson said, “The goal is to enable people to become creators, not just consumers, in this mobile world.” Abelson also stated, “We could only have done this because Android’s architecture is so open.”The App Inventor was tested by women, sixth grade students, nursing students and many others, none of them majoring in computer science.• PhysOrg.com Android apps (new version available) Google Android Application Inventor makes just about anyone a DIY Android App inventor Inserting buttons, blocks and customizing screen colors is just a click away.

Subtle Differences In Brain Cells Hint at Why

first_img by NPR News Jon Hamilton 8.21.19 1:23pm In mice, scientists have used a variety of drugs to treat brain disorders including murine versions of Alzheimer’s disease, depression and schizophrenia. But in people, these same treatments usually fail. And now researchers are beginning to understand why. A detailed comparison of the cell types in mouse and human brain tissue found subtle but important differences that could affect the response to many drugs, a team reports Wednesday in the journal Nature.”If you want to develop a drug that targets a specific receptor in a specific disease, then these differences really matter,” says Christof Koch, an author of the study and chief scientist and president of the Allen Institute for Brain Science in Seattle.One key difference involved genes that cause a cell to respond to the chemical messenger serotonin, says Ed Lein, a study author and investigator at the institute. “They’re expressed in both mouse and human, but they’re not in the same types of cells,” Lein says. As a result, “serotonin would have a very different function when released into the cortex of the two species.”That’s potentially a big deal because antidepressants like Prozac act on the brain’s serotonin system. So testing these drugs on mice could be misleading, Lein says.The comparison was possible because of new technology that allows scientists to quickly identify which of the hundreds of types of brain cells are present in a particular bit of brain tissue.The technology does this by detecting which genes are switched on in each cell. That reveals a genetic signature indicating the type of cell.”In one fell swoop you can get a more or less comprehensive understanding of all of the different types of cells that make up a brain region,” Lein says.This also makes it much easier to compare brain tissue from different species, he says.”We now have access to this fine level of resolution in the human brain and the ability to compare across and see how good a model a mouse or a monkey actually is,” Lein says.The list of cell types also should help researchers see what goes wrong in human brain disorders, Koch says.”A lot of neurological diseases, a lot of psychiatric diseases that we’re suffering from are due to specific defects in particular types of cells,” Koch says.For example, Parkinson’s disease affects brain cells that make a substance called dopamine. And epilepsy involves special cells that tamp down brain activity.Now, researchers have a way to make sure the types of cells involved in a particular disease work the same way in people as in an animal model, Koch says.”The technology finally caught up with what we’ve been needing to do for probably over 40 years,” says Tomasz Nowakowski, an assistant professor of anatomy at the University of California, San Francisco who co-wrote an editorial that accompanied the study. To compare mouse and human brain cells, researchers first analyzed sixteen thousand human brain cells taken from the middle temporal gyrus, a part of the cortex, the brain’s outermost layer. Then they looked at cells taken from the same area of a mouse brain.”In one sense, they are remarkable similar,” Koch says, noting that both mice and people had about 100 different types of cells in this region of the brain.But a close comparison of 75 of these brain cell types revealed small differences.Nowakowsky is especially intrigued by the finding that cells called microglia have a slightly different genetic signature in mice and people.”Those cells are the immune cells of the brain,” he says. “And you might imagine that studies or insights into neuroimmune disorders, for example, might be vastly affected by this difference.”Neuroimmune disorders include multiple sclerosis, systemic lupus, and amyotrophic lateral sclerosis. But there’s growing evidence that microglia also play an important role in Alzheimer’s disease.And that could be one reason experimental Alzheimer’s drugs have helped mice, but not people.Copyright 2019 NPR.

Trauma care centres to come up in major hospitals across Bengal

first_imgKolkata: The state government has chalked out a detailed plan to set up trauma care centres at various hospitals in the state, to ensure quick treatment to accident victims. The government will bear a cost of around Rs 45 crore for the construction of the trauma care centres and for buying equipments.According to initial plans, eight trauma care centres would be constructed in the first phase. The locations would be on or near national and state highways and other important roads. Also Read – Heavy rain hits traffic, flightsIt has been learnt that three trauma care centres would be located at SSKM Hospital, Bardhaman Medical College and Hospital (BMCH) and North Bengal Medical College and Hospital (NBMCH), while three others would be constructed at Kharagpur, Asansol and Islampur. The remaining two will be set up at Singur and Amtala.The critical patients would be admitted in the trauma care centres on an emergency basis. Accident victims or any trauma patient will be kept in the centres, where the patients would be given special care. These trauma care centres will have all the modern facilities to handle such patients.

It is important to transfer these patients to a hospital equipped with trauma care facilities. This could save lives of many accident victims in the state, the senior officials of the state Health department said.The construction of the trauma care centre at BMCH has already been done. There will be 25 beds – 10 general, 10 critical care and five step down or high-dependency units (HDU). Accidents victims in the area are often brought to the city’s hospital and it takes a long time to shift a critical patient to the city. Had there been a trauma care unit at BMCH, people meeting with road accidents in the area can be provided treatment faster. The trauma care centre at NBMCH will be made operational soon.According to the Health department sources, the largest trauma care centre is coming up at the SSKM Hospital. It is expected that it can be made operational within September this year. Those coming up at BMCH, NBMCH and Singur will be of level 2 category, while the ones at Kharagpur and Islampur will be of level 3 category. A trauma care centre was inaugurated at RG Kar Medical College and Hospital, a few months ago. It may be mentioned that RG Kar Medical College and Hospital is the first medical college hospital in the state to have a separate dedicated building for trauma care. The eight-storeyed building of the trauma care unit has departments like medicine, neuro-medicine, neuro-surgery, orthopedic and anesthesiology. Patients are availing specialised health care facilities under the same roof. The new building has 150 beds.last_img read more
