Dec 17: A team of US researchers has developed a diagnostic test for anti-microbial resistance using a smartphone that can help people in remote areas with limited resources conduct routine testing for antimicrobial susceptibility.

microbialAntimicrobial-resistant bacteria are responsible for high-mortality diseases such as pneumonia, diarrhea and sepsis.

The team from the University of California - Los Angeles (UCLA) built a simple and inexpensive smartphone attachment that can conduct automated anti-microbial susceptibility testing.

"This work is important and timely, given that drug-resistant bacteria are increasingly becoming a global threat, rendering many of our first-line antibiotics ineffective," said Aydogan Ozcan, Chancellor's Professor at the UCLA.

The device connects to a smartphone and has a plate that can hold up to 96 wells for testing.

An array of LEDs illuminates the sample and then the phone's camera is used to sense small changes in light transmission of each well containing a different dose selected from a panel of antibiotics.

Images are then sent to a server to automatically perform anti-microbial susceptibility testing and the results are returned to the smartphone in about one minute with a detection accuracy of 98.2 per cent.

"This mobile reader could eliminate the need for trained diagnosticians to perform anti-microbial susceptibility testing, reduce the cost barrier for routine testing and assist in tracking of bacterial resistance globally," said Omai Garner, a team member.

An additional advantage of this technology is the possibility of examining bacterial growth in the presence of a drug at an earlier time point than is currently read.

"This could allow for a more rapid turnaround time of the results to the physician, which might help save lives," added Dino Di Carlo, another team member.

New Delhi, Aug 2: The National Commission for Women (NCW) has issued notice to some Bollywood celebrities named in a complaint against the promoter of a company for allegedly blackmailing and sexually assaulting a number of girls on the pretext of giving them a career in modelling.

Taking cognizance of the complaint filed by social activist Yogita Bhayana of People Against Rape in India (PARI), the NCW scheduled a virtual hearing presided by its chairperson on August 6.

The complaint against Sunny Verma, promoter of a company named IMG Ventures with its headquarter in Chandigarh, alleged that he has been blackmailing and sexually assaulting a number of girls on the pretext of giving them career in modelling.

PARI's Yogita Bhayana wrote a complaint letter to NCW chairperson Rekha Sharma.

"Through his company, he (Sunny Verma) invites the girls on the pretext of organising a Miss Asia contest with a claim that the contest will launch them as models. To make it look genuine, his company has also been taking an entry fee of Rs 2,950. Once the girls apply, they are alluded by the female accomplices of Sunny Verma to submit their nude pictures in order to get the better ranking in the contest," the complaint letter said on July 31.

It alleged that Verma, after receiving the pictures and sometimes even before, used to get in touch with the girls and ask for completely nude pictures and videos.

The complaint letter said that Verma also used to allude as well as threaten the girls to submit to his sexual desires if they were interested in modelling as a career or wish to win the contest.

"Once he established a physical relationship with the girls, he used to blackmail them for regular sexual favours. Many girls from across the country have suffered a sexual and mental assault from Sunny and his accomplices," said the complaint citing several letters, texts and audio clips from several girls as proof of this modus operandi of Sunny Verma and his company.

The complaint also said that Sunny Verma has been previously also arrested on charges of sexual assault.

"We would demand that NCW should investigate the case to its depth and get the guilty punished so that any other person should not dare to exploit these kinds of innocent girls on any pretext. It will be a message to people like Sunny Verma and all associated Bollywood stars. Looking forward to strict action from NCW against sexual offenders like Sunny Verma & others," the complaint said.

The Covid-19 pandemic has made an unprecedented impact on the Indian businesses, particularly small and medium enterprises (SMEs) and startups. According to a joint survey by FICCI and Indian Angel Network (IAN), the pandemic has hit the businesses of around 70% startups.

With uncertainty in the business environment and an unexpected shift in priorities of the government as well as corporates, many startups are struggling to survive, it says.

In a nationwide survey on the 'Impact of Covid-19 on Indian Startups' involving 250 startups, 70% participants said their businesses had been impacted by Covid-19 and around 12% had shut operations.

The survey shows only 22% startups have cash reserves to meet the fixed cost expenses over the next 3-6 months, and 68% are reducing operational and administrative expenses.

Around 30% of the companies said they would retrench employees if the lockdown was extended too long. The 43% startups have already started 20-40% salary cuts over April-June.

Over 33% startups said investors had put the investment decision on hold and 10% said the deals had been scrapped. Only 8% startups had received funds as per the deals signed before Covid-19 outbreak, the survey revealed.

The reduced funding has forced startups to put a hold on business development and manufacturing activities, which has resulted in loss of projected orders.

The survey highlights the need of an urgent relief package for startups, including possible purchase orders from the government, tax relief and swifter tax refunds, and immediate fiscal support measures, including grants, soft loans and payroll grants.

Besides 250 startups, 61 incubators and investors also participated in the survey.

While 96% of investors accepted that their investments in startups had been impacted by Covid-19, 92% said their investments in startups would continue to be low over the next six months.

Around 59% investors said they would prefer to work with the existing portfolio firms in the coming months. Only 41% said they would consider new deals.

"A comparison of priority investment sectors before and during Covid-19 shows 35% investors are now looking at investments in healthcare startups, followed by EdTech, AI/Deep Tech, FinTech and Agri," said the survey.

Around 44% incubators surveyed said their day-to-day operations had been considerably hit by Covid-19. Most incubators are now supporting their portfolio firms by providing them virtual platforms to interact with mentors, investors and industries.

Dilip Chenoy, FICCI Secretary General, said, "The startup sector is stressed for survival at the moment. The investment sentiment is also subdued and is expected to remain so in the coming months. Lack of working capital and cash flows may lead to major layoffs over the next 3-6 months."

Indian startups needed an enabling ecosystem and flow of funds to continue operations, the survey said.

Padmaja Ruparel, President, Indian Angel Network & Co-Chair of FICCI Startup Committee, said, "In these uncertain times, as investors, we must play an important role to provide the Indian startups funding, mentoring and hand-holding support to stay afloat and come out at the other end of this crisis."

To that end, IAN recently announced a debt fund to help IAN portfolio companies raise working capital and ensure business continuity by partnering with debt providers.

This must be replicated on a wider scale, so a larger number of startups are provided the capital support to make it during these tough times, Ruparel said.

As millions of people get hooked to online dating platforms, their proliferation has led to online romance scams becoming a modern form of fraud that have spread in several societies along with the development of social media like Facebook Dating, warn researchers.

For example, extra-marital dating app Gleeden has crossed 10 lakh users in India in COVID-19 times while dating apps like Tinder and Bumble have gained immense popularity.

According to researchers from University of Siena and Scotte University Hospital led by Dr Andrea Pozza, via a fictitious Internet profile, the scammer develops a romantic relationship with the victim for 6-8 months, building a deep emotional bond to extort economic resources in a manipulative dynamic.

"There are two notable features: on the one hand, the double trauma of losing money and a relationship, on the other, the victim's shame upon discovery of the scam, an aspect that might lead to underestimation of the number of cases," the authors wrote in a paper published in the journal Clinical Practice & Epidemiology in Mental Health.

Around 1,400 dating sites/chats have been created over the last decade in North America alone. In the UK, 23 per cent of Internet users have met someone online with whom they had a romantic relationship for a certain period and even 6 per cent of married couples met through the web.

"The online dating industry has given rise to new forms of pathologies and crime, said the authors.

The results showed that 63 per cent of social media users and 3 per cent of the general population reported having been a victim at least once.

Women, middle-aged people, and individuals with higher tendencies to anxiety, romantic idealization of affective relations, impulsiveness and susceptibility to relational addiction are at higher risk of being victims of the scam.

Online romance scams are, in other words, relationships constructed through websites for the purpose of deceiving unsuspecting victims in order to extort money from them.

The scammer always acts empathetically and attempts to create the impression in the victim that the two are perfectly synced in their shared view of life.

"The declarations of the scammer become increasingly affectionate and according to some authors, a declaration of love is made within two weeks from initial contact," the study elaborated.

After this hookup phase, the scammer starts talking about the possibility of actually meeting up, which will be postponed several times due to apparently urgent problems or desperate situations such as accidents, deaths, surgeries or sudden hospitalizations for which the unwitting victim will be manipulated into sending money to cover the momentary emergency.

Using the strategy of "testing-the-water", the scammer asks the victim for small gifts, usually to ensure the continuance of the relationship, such as a webcam, which, if successful, leads to increasingly expensive gifts up to large sums of money.

When the money arrives from the victim, the scammer proposes a new encounter.

The request for money can also be made to cover the travel costs involved in the illusory meeting. In this phase, the victim may start having second thoughts or showing doubt about the intentions of the partner and gradually decide to break off the relationship.

"In other cases, the fraudulent relationship continues or even reinforces itself as the victim, under the influence of ambivalent emotions of ardor and fear of abandonment and deception, denies or rationalizes doubts to manage their feelings," said the study.

In some cases, the scammer may ask the victim to send intimate body photos that will be used as a sort of implicit blackmail to further bind the victim to the scammer.

Once the scam is discovered, the emotional reaction of the victim may go through various phases: feelings of shock, anger or shame, the perception of having been emotionally violated (a kind of emotional rape), loss of trust in people, a sensation of disgust towards oneself or the perpetrator of the crime and a feeling of mourning.

"Understanding the psychological characteristics of victims and scammers will allow at-risk personality profiles to be identified and prevention strategies to be developed," the authors suggested.
