A new study of a brain region involved in learning and memory, and responses to stress and epilepsy, has found that male and female brains operate differently at a molecular level.The findings suggest that female and male brains may respond differently to certain drugs.Also read: Men more likely to be obese than women”The importance of studying sex differences in the brain is about making biology and medicine relevant to everyone, to both men and women,” said senior author of the study Catherine Woolley, professor at Northwestern in Illinois, US.”It is not about things such as who is better at reading a map or why more men than women choose to enter certain professions,” Woolley explained.Among their findings, the scientists found that a drug called URB-597, which regulates a molecule important in neurotransmitter release, had an effect in females that it did not have in males.While the study was done in rats, it has broad implications for humans because this drug and others like it are currently being tested in clinical trials in humans.To find out what is the same and what is different between males and females, scientists need to study both sexes, Woolley maintained.Currently, about 85 percent of basic neuroscience studies are done in male animals, tissues or cells.”We are not doing women–and specifically women’s health–any favours by pretending that things are the same if they are not,” Woolley said.”If the results of research would be different in female animals, tissues and cells, then we need to know. This is essential so that we can find appropriate diagnoses, treatments and, ultimately, cures for disease in both sexes,” she pointed out.advertisementThe study was published in The Journal of Neuroscience.
Game of ThronesGame of Thrones Official YoutubeThe final season of Game of Thrones has not lived up to expectations, be it the story, character arcs or the technical details of the show, like the lighting in episode 3 or the coffee cup min episode 4. Fans are dissatisfied by season 8. And to make things worse, reportedly a minute-long preview for the last two episodes of Game Of Thrones’ eighth season was allegedly leaked on Monday, leaving fans livid over the show’s potential ending.According to The Sun, the footage is believed to show major spoilers for the battle of King’s Landing, as well as how the show will end in episode six. Viewers, who had seen the potential spoilers on Twitter, were furious at the prospect of what the leak could mean, with some even going as far as to say that it meant the show had ‘the worst ending in TV history.’ That seems like quite a claim but the way the final season has been progressing, we have to say that we are a little apprehensive about what the last two episodes hold for fans. Game of Thrones season 8 episode 4Game of Thrones (@gameofthrones/Instagram)Spoilers for Episode 4 ahead.The last episode was disappointing as well, with character development and story arcs abandoned at the drop of a hat. Jaime Lannister abandons Brienne of Tarth after making love to her, Brienne of Tarth, a strong, independent warrior Knight is reduced to a sniveling stereotype of a lovestruck woman. And a Dragon is shot down from in the air in an apparent impossible shot. Why? So that the final battle is an even match between Daenerys Targaryen and Cersei Lannister.The fifth episode of the final season of Game of Thrones will air on May 12.
Chief election commission (CEC) KM Nurul HudaChief election commissioner (CEC) KM Nurul Huda on Saturday said Election Voting Machine (EVM) will be used on a limited scale in the next national election to check vote rigging as well as protect the interest and dignity of voters.The CEC came up with the remark while inaugurating the EVM Fair at Public Hall in Khulna city.Although EVM will not be imposed by force, the Election Commission has a plan to use this machine on a smaller scale in the next general election considering the law and opinion of others, he said.The EVM system has been launched to ensure transparency and a rigging-free voting to secure the interest of voters, he said.In the current system, irregularities can occur in handling the ballot papers but EVM can eliminate such irregularities, Nurul Huda said.Chaired by deputy commissioner Md Helal Hossain, the programme, was attended, among others, by divisional commissioner Lokman Hossain Mia, deputy inspector general of police Md Didar Ahmad, KMP commissioner Humayun Kabir and police super SM Shafiullah.

The researchers found that the microbots can remove 95% of the lead in polluted water in one hour, and can be reused multiple times, potentially offering a more effective and economical way to remove heavy metals than previous methods. Microbots individually controlled using ‘mini force fields’ More information: Diana Vilela, et al. “Graphene-Based Microbots for Toxic Heavy Metal Removal and Recovery from Water.” Nano Letters.

These activities produce metals such as lead, arsenic, mercury, cadmium, and chromium, all of which pose a safety hazard to living organisms and the environment.In the new study, the researchers focused specifically on removing lead from wastewater by designing tube-shaped microbots with three functional layers. The outer layer of graphene oxide adsorbs the lead from the water. The middle layer, nickel, makes the microbots ferromagnetic so that their direction of motion can be controlled by an external magnetic field. The inner layer, platinum, gives the microbots the ability to self-propel themselves through water. When hydrogen peroxide is added to the wastewater, the platinum decomposes the hydrogen peroxide into water and oxygen microbubbles, and ejecting the microbubbles from the back of the microbot propels it forward.

Then the microbots are treated in an acidic solution to remove the lead ions, which can later be recovered and reused. The microbots can also be reused for further lead clean-up. “This is a new application of smart nanodevices for environmental applications,” Sánchez said. “The use of self-powered nanomachines that can capture heavy metals from contaminated solutions, transport them to desired places and even release them for ‘closing the loop’—that is a proof-of-concept towards industrial applications.”In the future, the microbots could even be controlled by an automated system that magnetically guides the swarm to accomplish various tasks. “We plan to extend the microbots to other contaminants, and also importantly reduce the fabrication costs and mass-produce them,” Sánchez said.The combination of self-propelled robots with functional layers also opens the doors for similar designs that could have applications in areas including drug delivery and sensing. © 2016 Phys.org

Kolkata: Medical Bank has opened emergency helpline to cope with the shortage of blood during the Durga Puja.In case of any emergency, people can call 98310-62157, D Ashis, secretary of Medical Bank said.He said as there are few blood donation camps because of the Puja, there is severe shortage in the blood banks. There are 70 blood banks run by the state government in the state while another 16 are run by the Centre along with 35 private blood banks. The annual requirement in the state is around 15 lakh units while around 11.5 lakh units are collected through various blood donation camps. Also Read – Rain batters Kolkata, cripples normal lifeD Ashis said it is really unfortunate that most of the Puja committees are not concerned about the shortage of blood. “Thousands of people from other states and countries come to Kolkata during Durga Puja and if they need blood, it will difficult to get a unit.”To address this issue, it would have been ideal had the Puja committees put up the hoardings containingthe names of the persons willing to donate blood during the Pujas.Also, though the state-run blood banks are open during the Durga Puja, no collection and examination of blood samples are done after sundown because of shortage of staff.He urged the state government to open the examination of blood samples facilities round the clock.
Taylor Swift fans hoping to watch the pop singer’s concert on Apple Music on Sunday were instead greeted by “Blank Space.”The superstar’s concert documentary, The 1989 World Tour Live, was set to go live on Dec. 20, but the premiere of the film, which is exclusive to the Apple Music platform, wasn’t as smooth as the tech giant would have liked.Meant to be available for viewing on iPads, iPhones, iPod touch, Macs and PCs with iTunes and Apple TV, fans were met with crashes, glitchy streaming or the inability to even locate the movie. Since Sunday morning, Apple Music Help twitter account has continued to field customer-service requests from frustrated users as of this story.Related: Taylor Swift’s Latest Trademark Filings Reveal a Shrewd Business Strategy@bentisdell We’d like to look into this with you.

Follow up in a DM.— Apple Music Help (@AppleMusicHelp) December 21, 2015Ahead of the Apple Music launch in July, Swift took to Tumblr in a post titled, “To Apple, Love Taylor,” to take the company to task about how during the streaming service’s three-month trial period, the artists, writers and producers in question would not be compensated.Related: Why Taylor Swift Is Now the Most Powerful Person in TechLikely not looking to run afoul of Swift and her sizable music industry clout (especially given how much attention was paid to the singer’s decision to remove her music from Spotify in 2014) , Eddy Cue, Apple’s senior vice president of Internet and software, tweeted to Swift that the company would change its policy.#AppleMusic will pay artist for streaming, even during customer’s free trial period— Eddy Cue (@cue) June 22, 2015We hear you @taylorswift13 and indie artists. Love, Apple— Eddy Cue (@cue) June 22, 2015Back in October, Apple CEO Tim Cook said that the music streaming service had more than 15 million users, with 6.5 million paying the $9.99 monthly subscriber fee. And in December, with all forgiven between the two giant business entities — Apple Music was the lone streaming service to offer the massive hit album 1989 to listeners — Swift announced the streaming deal with Apple on Twitter, on her birthday earlier this month. Judging by the volume of complaints, it seems like the partnership will work out quite nicely for both parties once the technical difficulties are resolved.Related: Yes, Believe It: Taylor Swift Is a Customer Retention Expert Growing a business sometimes requires thinking outside the box. 3 min read December 21, 2015 Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now »
