​Barcelona, Feb 27 (IANS) Seventeen years after its debut, the much-awaited Nokia 3310 has been relaunched in an all new revamped look featuring a colour screen at the Mobile World Congress (MWC) here. The device, to be sold under licence by the Finnish start-up HMD Global, is available in four distinctive colours - gloss-finished warm red and yellow, and a matte-finished dark blue and grey. It will cost buyers only 49 Euros ($52) and will be available from the second quarter of this year. Considered as iconic because of its popularity and sturdiness, Nokia sold more than 126 million devices before it was phased out in 2005. "Our efforts in bringing together world class manufacturers, operating systems and technology partners sees us proudly unveiling our first global portfolio of smartphones with a Nokia soul, delivering the very best experience to everyone," Arto Nummela, CEO of HMD Global, said in a statement. Having a 2.4-inch display, the new Nokia 3310 qualifies as a "feature phone" rather than a smartphone as it only provides limited internet facilities. It relies on 2.5G connectivity and is powered by the S30+ operating system. With 1,200mAh battery, the device offers a 22 hours of talk time and has up to a month's standby time. The battery of the new device is removable, like its older version. However, the 2017 model is rechargeable through a microUSB port. Its single camera is also restricted to 2MP. According to HMD Global, which owns the rights to the Nokia brand, the device also comes with the modern version of the classic game Snake pre-installed. The device will power through up to 51 hours of MP3 playback too, as well as up to 39 hours of FM radio playback. "What HMD has created is remarkable. We're excited to see the launch of a new family of smartphones, built to the standards that Nokia is known for." "We believe that their strong design and quality will appeal to Nokia fans around the world and the return of the Nokia 3310 has us smiling too!" Brad Rodrigues, interim President of Nokia Technologies, added. HMD also confirmed the Nokia 6 Android smartphone would be released worldwide following its China debut in January. The device has a 16MP rear camera and a 5.5-inch 1080p display. The new range of Nokia smartphones run on Android Nougat OS and offer a pure and secure experience with an all-feature Google Assistant. The unibody of the Nokia 6 is crafted from a single block of 6000 series aluminium. The smart audio amplifier with dual speakers allow consumers to experience a deeper bass and clarity, whilst Dolby Atmos sound delivers a powerfully moving entertainment experience. Available in four colours - Matte Black, Silver, Tempered Blue and Copper - the Nokia 6 will retail at an average global retail price of 229 Euros ($242). With 64GB storage and 4GB RAM, Nokia also unveiled Nokia 6 Arte Black Limited Edition available for retail price of 299 Euros ($315). In addition, the firm showed off smaller, lower-range Nokia 5 and Nokia 3 models. Nokia 5 has a Corning Gorilla Glass laminated 5.2-inch IPS HD display. It is powered by the Qualcomm Snapdragon 430 processor and is available in four colours -- Matte Black, Silver, Tempered Blue and Copper. It is priced at 189 euros ($199). The Nokia 3 has a Corning Gorilla Glass laminated 5-inch display and 8MP wide aperture front and back cameras. Available in four distinctive colours -- silver white, matte black, tempered blue and copper white - the Nokia 3 will retail at an average global retail price of 139 euros ($146).

​Phnom Penh, Feb 27 (IANS) Cambodian Prime Minister Hun Sen said on Monday announced that the country's tourism sector earned $3.4 billion in 2016.

The Southeast Asian nation attracted 5 million international visitors last year, a 5 per cent rise year-on-year, according to a tourism data, Xinhua news agency reported. 

"We predict that Cambodia will welcome 5.4 million foreigners in 2017 and up to 7 million in 2020 with estimated revenue of $5 billion," Hun Sen said. 

He said that tourism industry currently provides some 620,000 direct jobs and the number of jobs will reach 1 million in 2020.

According to the Prime Minister, the country's peace and political stability were the prerequisites for the attraction of tourists.

"Tourists will not risk their lives to visit dangerous or war zones...so maintaining peace and political stability and preventing terrorism from happening in Cambodia are very important," he said, vowing to maintain the country's peace "at any cost".

Cambodia is famous for the 12th century Angkor Archeological Park in Siem Reap province. 

Besides, it has a 450-km pristine coastline stretching across four provinces in the country's southwestern part.

New Delhi, Feb 27 (IANS) The WHO on Monday said it it has published the first-ever list of antibiotic-resistant "priority pathogens", 12 families of bacteria that pose the greatest threat to human health, to guide and promote research and development of new antibiotics.

The Geneva-based World Health Organisation (WHO) said that list was drawn up as part of its efforts to address growing global resistance to antimicrobial medicines.

According to the global health body, the list is divided into three categories according to the urgency of need for new antibiotics: critical, high and medium priority.

"The most critical group of all includes multi-drug resistant bacteria that pose a particular threat in hospitals, nursing homes, and among patients whose care requires devices such as ventilators and blood catheters. They include Acinetobacter, Pseudomonas and various Enterobacteriaceae (including Klebsiella, E. coli, Serratia, and Proteus)," said a WHO statement.

It said that all the bacteria can cause severe and often deadly infections such as bloodstream infections and pneumonia.

"These bacteria have become resistant to a large number of antibiotics, including carbapenems and third generation cephalosporins - the best available antibiotics for treating multi-drug resistant bacteria," said the report.

The second tier which includes antibiotics of high priority includes for Enterococcus faecium, which is vancomycin-resistant, Staphylococcus aureus which is methicillin-resistant, Helicobacter pylori which is clarithromycin-resistant, Campylobacter spp which is fluoroquinolone-resistant, Salmonellae which is fluoroquinolone-resistant, Neisseria gonorrhoeae which is cephalosporin and fluoroquinolone-resistant.

The third tier which includes medium priority includes Streptococcus pneumoniae which is penicillin-non-susceptible, Haemophilus influenzae, which is ampicillin-resistant and Shigella spp which is fluoroquinolone-resistant.

"This list is a new tool to ensure research and development responds to urgent public health needs," said WHO's Assistant Director-General for Health Systems and Innovation Marie-Paule Kieny in the statement.

Evelina Tacconelli, Head of the Division of Infectious Diseases at the University of Tübingen and a major contributor to the list, said :"New antibiotics targeting this priority list of pathogens will help to reduce deaths due to resistant infections around the world. 

"Waiting any longer will cause further public health problems and dramatically impact on patient care."

New York, Feb 26 (IANS) Although the last Neanderthal died tens of thousands years ago, their DNA sequences still influence how genes are turned on or off in modern humans, and their effects can contribute to traits such as height and susceptibility to schizophrenia or lupus, says a study.

Experts know that after leaving Africa, our ancestors -- the homo sapiens -- mated with Neanderthals thousands of years ago, and today Neanderthal DNA makes up one to four per cent of the genomes of modern non-African people. 

"Even 50,000 years after the last human-Neanderthal mating, we can still see measurable impacts on gene expression," said study co-author Joshua Akey from the University of Washington School of Medicine in Seattle.

"And those variations in gene expression contribute to human phenotypic variation and disease susceptibility," Akey added.

Previous studies have found correlations between Neanderthal genes and traits such as fat metabolism, depression, and lupus risk.

In this study, published in the journal Cell, researchers analysed RNA sequences in a dataset called the Genotype-Tissue Expression (GTEx) Project, looking for people who carried both Neanderthal and modern human versions of any given gene -- one version from each parent. 

For each such gene, the investigators then compared expression of the two alleles head-to-head in 52 different tissues.

"We find that for about 25 per cent of all those sites that we tested, we can detect a difference in expression between the Neanderthal allele and the modern human allele," added Rajiv McCoy, post-doctoral researcher at the University of Washington.

One example uncovered by this study is a Neanderthal allele of a gene called ADAMTSL3 that decreases risk of schizophrenia, while also influencing height.

"Hybridisation between modern humans and Neanderthals increased genomic complexity," Akey explained.

"Hybridisation wasn't just something that happened 50,000 years ago that we don't have to worry about anymore. Those little bits and pieces, our Neanderthal relics, are influencing gene expression in pervasive and important ways," Akey said.

New York, Feb 25 (IANS) Researchers have found a 700-per cent surge in infections caused by bacteria that is resistant to multiple kinds of antibiotics among children in the US.

According to researchers, these antibiotic resistant infections -- caused by Enterobacteriaceae, a family of bacteria that also include such pathogens as Salmonella and Escherichia coli -- are linked to longer hospital stays and potentially greater risk of death.

The findings showed that the proportion of these infections in children caused by bacteria increased from 0.2 per cent in 2007 to 1.5 per cent in 2015, a more than 700 per cent increase in prevalence over the eight-year period.

"There is a clear and alarming upswing throughout US of antibiotic resistant Enterobacteriaceae infections in kids and teenagers," said lead author Sharon B. Meropol, a pediatrician and epidemiologist at Case Western Reserve University in the US. 

Bacterial infections resistant to multiple drugs are especially concerning in children, for whom there are a limited number of stronger antibiotics currently approved for use compared to adults, putting kids at higher risk for worse outcomes, the researchers said. 

For the study, published in the Journal of the Pediatric Infectious Diseases Society, the team analysed data from 48 children's hospitals throughout the US, focusing on approximately 94,000 patients under the age of 18 who were diagnosed with Enterobacteriaceae - associated infections between 2007 and 2015. 

More than 75 per cent of the antibiotic-resistant infections were already present when the young people were admitted to the hospital, upending previous findings that the infections were mostly picked up in the hospital. 

This suggested that the bacteria may be increasingly spreading in the community. 

In addition, the bacterial infection may also cause a greater mortality risk among pediatric patients.

"Health care providers have to make sure we only prescribe antibiotics when they're really needed. It's also essential to stop using antibiotics in healthy agricultural animals", Meropol added.
