Scientists Discover New Antibiotic, A Potential Weapon Against a Range of Diseases

Scientists have discovered a powerful new antibiotic they say can kill an array of germs without the bugs easily becoming resistant to it, a potential weapon against a range of diseases.
The discovery is a rare—and much-needed—breakthrough in the quest for new antibiotics to overcome the problem of growing resistance to existing drugs. While the new compound was shown to be safe and effective in mice, scientists need to determine whether this is the case for people.
The discovery of the new class of antibiotic, called teixobactin, was reported Wednesday in the journal Nature. It was uncovered by screening 10,000 bacterial strains from soil. Teixobactin will be investigated further in animals before being tested in people.
If all goes well, “we’ll be in clinical trials two years from now,” said Kim Lewis, a professorat Northeastern University in Boston and lead author of the study. Human trials could take two to three years, he added.
Antibiotics, discovered in the early 20th century, transformed medicine. Most are chemical substances extracted from certain bacteria that can kill or damage other bacteria that cause human and animal diseases.
Because of widespread and indiscriminate use of antibiotics, bacteria in recent years have acquired mutations and new genes that render them more resistant to drugs. At the same time, antibiotic research at pharmaceutical companies stalled.

Communist party launches 'China Operating System' to oust iOS and Android

hina officials have launched a national operating system in an attempt to take back control of the country’s computer market from American companies such as Google and Apple. The software has been in development for more than a year, but has been released at a crucial time with revelations about US-led surveillance sparking fears over the integrity of American-designed software. Known simply as the China Operating System, or COS, the software can run on PCs, tablets and smartphones and has been based on the open-source Linux operating system. Chinese media say that the OS has been created “entirely independently” in order to provide better localization for a range of features – from Chinese-language keyboards, to integration with the country’s banks. At the launch of the event, one of the developers involved with the project reportedly criticized Western software , saying that Apple’s iOS was too closed, that Google’s Android OS suffered from fragmentation (ie, too many versi...

How to use home loans most effectively for tax benefits

1) Deduction on interest: If you are paying EMIs for a home loan you took to buy a house, the interest component in the EMI can be claimed as deduction. You must be both an owner and a co-borrower (in the loan) to claim tax benefits. This deduction can be claimed starting the year in which the construction of the house is completed. Suppose the construction of your house was completed on August 30, 2014, you can claim deduction for interest for the entire 12 months in financial year 2014-15. So every year a maximum of Rs. 2 lakh can be claimed for a house that you use for your own residence. If your house is rented, the entire interest for the year can be claimed as deduction. The interest payments for the year shall result in a loss under the head 'income from house property'. This loss can be adjusted against in the same year against other heads of income in your income tax return including salary. Therefore, it reduces your total taxable income and the tax you pay thereon. A...
