Singapore Caregiving Platform Homage Hustles To Keep Up With Demand For Care As Asia Ages

As Asian populations improve older, Homage CEO Gillian Tee is escalating the electronic platform’s pool of caregivers, nurses and doctors to meet up with increasing desire.


Gillian Tee was 10 when the aged nanny who helped increase her handed away from most cancers. That expertise, and a shut bond with her grandmother, manufactured Tee informed of the everyday support desired by many seniors, and the battle households encounter in getting capable treatment. In excess of two decades later she cofounded Singapore-based mostly Homage, which these days claims to have the most significant pool of caregivers in the city-condition that households can employ the service of by an application.

“I feel most folks in health care startups commence in the market mainly because they had some individual experiences,” states the 40-year-aged CEO by online video. The personal computer science graduate (College of Melbourne) bought her to start with style of working a enterprise soon after finding an M.B.A. from Columbia College. In 2012, she cofounded New York-dependent ticket reserving platform Rocketrip. A couple of decades later she moved again to Singapore to be nearer to spouse and children, where she noticed an opportunity to marry digital technological know-how with dwelling-based care expert services. “I actually believed in the idea of executing properly by performing good,” she claims of her choice to start Homage with cofounders Lily Phang and Tong Duong, who have considering that still left the corporation.

Considering that launching in 2016, Homage has grown to 15,000 section- and comprehensive-time caregivers, expanded to Malaysia and Australia, and lifted more than $45 million in funding from buyers like Sheares Healthcare Team, owned by Singapore point out fund Temasek, and Southeast Asia-concentrated Golden Gate Ventures.

The company’s go into Malaysia in 2018 assisted increase income by 170{4224f0a76978c4d6828175c7edfc499fc862aa95a2f708cd5006c57745b2aaca} to S$1.8 million ($1.3 million) in 2020, even though losses narrowed to S$4.8 million from S$5.8 million, in accordance to the most up-to-date readily available figures. Tee states income far more than tripled last yr and intercontinental revenues grew eightfold in the previous 18 months, next the company’s enlargement into Australia in 2021.

Homage, which produced the 100 to Look at checklist this 12 months, has also diversified past caregiving to incorporate solutions these as telemedicine, medication supply and the sale of medical goods. Tee is now targeted on tackling the challenge of retaining up with demand from customers for care as Asia ages. In Singapore, govt figures exhibit the number of people today aged 65 or in excess of created up virtually 17{4224f0a76978c4d6828175c7edfc499fc862aa95a2f708cd5006c57745b2aaca} of its resident populace in 2022.

Desire for skilled caregivers is increasing steadily not just in Singapore, but throughout the Asia-Pacific, dwelling to some of the world’s oldest and quickest getting old populations. In the up coming decade, the region will account for 60{4224f0a76978c4d6828175c7edfc499fc862aa95a2f708cd5006c57745b2aaca} of the world’s in excess of-65 population and will also have 250 million diabetics, according to Vikram Kapur, spouse and head of Asia-Pacific healthcare at consultancy Bain in Singapore. “Healthcare in this component of the planet is truly at a tipping issue,” Kapur states.

In Singapore and Malaysia—where the aged are largely cared for by household users, are living-in domestic support, or attendants in nursing properties or those people contracted from brick-and-mortar agencies—Homage’s electronic platform gives a market decentralized service in an progressively tech-savvy location. A report this year by Bain uncovered much more people today in Southeast Asia commenced employing electronic health care equipment because of constrained accessibility to in-man or woman appointments during the pandemic. As with on the internet food stuff shipping and delivery and fintech, lots of proceed to use digital health care due to the fact of its convenience, the report added. “Consumer expectations are altering a lot,” says Kapur. “For meals supply and other products and services, you get pretty much immediate obtain. But there’s disappointment with health care.”

Homage is hoping to fix that trouble by enabling family members to hire portion- and whole-time caregivers for periods ranging from a person hour to flexible prepaid packages of up to 200 several hours that it provides at released charges. Its application has about 15,000 downloads on the Google Perform store and the business claims to have offered extra than 1 million hrs of service to consumers. In comparison with Singapore’s Health care provider Anywhere—a popular telemedicine application with in excess of a million downloads in Southeast Asia that promises video clip consultation with a medical professional in under five minutes—Homage says it can arrange these types of virtual appointments in 30 minutes, as well as house calls in a day. It sends caregivers in just two times.

“During the pandemic, we observed that several stroke patients demanded telemedicine providers,” says Tee. “So, we have [telemedicine], which is an ancillary for the reason that it provides to the well-currently being of clients.” Homage’s shift into advertising healthcare and healthcare products such as blood stress displays is intended to also provide a need to have. “We will often target [on] the care recipient,” she states. “For case in point, what does a stroke affected individual need? We will always search at what can be a improved alternative for the affected individual.”

“I actually thought in the idea of accomplishing nicely by undertaking good.”

Gillian Tee, CEO of Homage

Tee’s also been occupied raising funds. There was an undisclosed “double-digit” collection B spherical in January 2020, led by EV Expansion, a joint venture concerning Southeast Asia-centered East Ventures, YJ Funds (a subsidiary of SoftBank-backed Z Holdings, now portion of its corporate undertaking capital arm Z Undertaking Money) and SMDV, backed by the billionaire Widjaja family’s Sinar Mas conglomerate in Indonesia. That followed a $4.15 million series A funding in 2018, led by Golden Gate Ventures and HealthXCapital.

In September past yr, the enterprise concluded a $30 million sequence C spherical, led by Temasek’s Sheares Health care, which invests in and delivers health care services in Asia. Homage says the money will be utilized to scale up its platform and double down on its overseas operations in Malaysia and Australia, which are its essential growth motorists. Having said that, Homage may possibly be hitting velocity bumps. In late Oct, a spokesperson for Homage explained the company “is building a several critical strategic alterations in response to the macro surroundings,” later including people improvements are in relation to its Australian growth ideas. When asked to clarify, the spokesperson did not reply.

To retain Homage on a expansion trajectory, Tee will have to conquer refreshing troubles of an uncertain financial ecosystem and recruiting health care gurus quickly plenty of from a dwindling expertise pool. “We’re not doubling nursing colleges each and every calendar year,” she claims. “So [supply] is linear, but the desire is expanding exponentially mainly because of the growing older inhabitants.”

The lack of caregivers for the aged is specially acute in Australia, Homage’s most recent market. “The pandemic has escalated burnout and lessened retention premiums,” suggests Sharon Hakkennes, vice president analyst at Gartner’s healthcare exercise. “Clinicians are leaving the occupation.” Australia’s aged care sector could facial area a lack of at minimum 110,000 staff in the up coming ten years, in accordance to a 2021 report by the Committee for Economic Progress of Australia, a nonprofit firm.

Hakkennes suggests electronic technologies such as Homage’s platform can aid reduce the scarcity by allowing health care specialists to accessibility and address individuals extra effectively. “[Digital technology] is heading to enable scale,” she claims. “And when we’re battling with the scientific workforce, that’s likely to be critical.” Moreover enabling aged care services to faucet into a “vetted pool of certified care gurus,” Homage claims on its Australian site that its platform enables buyers from varied backgrounds to accessibility caregivers who can talk 93 languages, including signal language.

Meanwhile, Tee is carrying out all she can to incentivize health care industry experts to join her company’s platform. In March 2020, Homage partnered with Singapore-dependent insurance policy technologies firm Gigacover to offer health care gains to all its healthcare specialists and their dependents. A month afterwards, Homage launched a fund to present them with financial guidance all through the peak of the pandemic. “Our treatment industry experts are our most important clients—they are our care recipients, if you want to set it that way,” says Tee. “We need to choose treatment of them. Why? So that they can get care of other people.”

The Path to a Carbon-Neutral Future Through Digital Technology and Platform Innovation

By Daniel Zhang

The sky is not the restrict. As corporations around the globe chart the finest system for mitigating greenhouse gasoline (GHG) emissions, the largest amongst us have not only the chance but also the accountability to make a much even larger effect than we have to support limit the weather disaster. We can’t basically meet up with proven guidelines. We ought to go above and past.

As a world-wide digital infrastructure company and system corporation, Alibaba signifies tens of millions of brand names and billions of buyers. That places us in a special situation to create a robust sustainability framework ideal to our size and industry presence that can guide us to meaningfully address the local climate challenges and support make a sustainable foreseeable future.

The Greenhouse Gas Protocol is the world’s most commonly made use of greenhouse fuel accounting typical for businesses. In this accounting program, which guides thousands of companies’ carbon neutrality actions, the independent Earth Sources Institute (WRI) and Environment Company Council for Sustainable Improvement (WBCSD) have delineated three scopes that advocate operational boundaries for organizations to account for and minimize their GHG emissions:

  • Scope 1 targets immediate GHG emissions from these kinds of organization-owned resources as vehicles, boilers and furnaces, and production equipment.
  • Scope 2 accounts for emissions from electrical energy a firm purchases from exterior resources and consumes.
  • Scope 3 accounts for other oblique emissions up and down during a company’s benefit chain ensuing from this sort of functions as useful resource extraction, transportation of fuels, and the use of its merchandise and solutions.

Although these a few scopes offer a robust framework for businesses to meet up with GHG emission ambitions, the most significant world-wide companies can—indeed, we must—push beyond this blueprint for carbon neutrality to assistance accomplish important adjust.

Alibaba has fully commited to be a part of the Science-Based Targets initiative (SBTi) to assistance limit the worldwide temperature improve to
1.5°C (2.7°F)
. In forming our plans, Alibaba initiated a detailed assessment of the GHG emission level for the first time.

Given the diversity and variance of our business ecosystem—encompassing digital commerce, nearby expert services, logistics, cloud computing, enjoyment, and more—the assessment has been unusually advanced. Yet we are self-confident that the elevated penetration of digitization and system innovation sets up Alibaba Group to support reach a strong changeover into a reduced-carbon circular economy that will help decarbonize not only our very own procedure but the overall value chain.

We created an ambitious target to obtain Scope 1 and 2 carbon neutrality and halve Scope 3 emission intensity by 2030. We assume to meet up with Scopes 1, 2, and 3 targets by 2030 as a result of digital transformation, using this kind of actions as lessening our emissions by way of far more successful procedures and vitality-conserving technological innovation shifting our power intake to renewable assets and prioritizing carbon reduction more than removal, and elimination around offsetting.

The Scope 3+ Objectives

But Alibaba’s ideas go beyond Scope 3.

We have expanded our ambitions to exceed those people goals as a result of Scope 3+, our commitment to minimize GHG emissions throughout our digital platform ecosystem by 1.5 gigatons from 2021 to 2035. Scope 3+ priorities incorporate sustainable consumption, sensible transportation, digitalizing the recommerce marketplace, low-carbon operations and management, and inexperienced logistics and recycling.

As we endeavor to even more determine, measure, and lower the emissions across our ecosystem, Alibaba invitations our global corporate and community-sector friends to join us, our companions, and our local community in meeting the ambitious carbon-neutrality plans of Scope 3+.

We entirely acknowledge that adopting actions as audacious as Scope 3+ involves additional than getting a closer glimpse at environmental, social, and governance (ESG) policy. It usually means a full transformation—changing overall organizational missions, cultures, and the way we function.

“This goes beyond the regular scope of responsibility that businesses take for emissions reduction—indeed, it seeks to measure emissions that are adjacent to their value chain, not right within just it,” states Peter Lacy, International Sustainability Services Lead and Main Accountability Officer at Accenture. “No one business has however thoroughly delivered on the potential of lowering ecosystem emissions and reworking an total end-to-stop worth chain at the scale Alibaba aspires to.”

Whilst it may possibly seem to be daunting at first, the sweeping transform of Scope 3+ carbon reduction is evidently achievable when we watch it as the aggregate end result of incremental digitization efforts that include the collaboration of all stakeholders—our employees, associates, and prospects. These initiatives can start out little and nevertheless encourage us to imagine larger by:

  • performing with manufacturers on our platform to create a devoted channel that promotes environmentally friendly usage and advocates for a sustainable eco-ahead way of living
  • supporting the circular economic climate to encourage the reuse of preowned items on Idle Fish, Alibaba’s secondhand-marketplace electronic system
  • encouraging a lot more recycling and the use of recycled packaging through Cainiao, Alibaba’s wise-logistics platform
  • assisting workplaces go far more fully digital—reducing power usage in workplaces and endorsing inexperienced transportation—through Alibaba’s robust cloud-computing infrastructure and DingTalk, its smart collaborative-work platform
  • using Alibaba Cloud’s solution and technological know-how innovations to aid our prospects discover higher vitality effectiveness, this sort of as with our demonstrated vitality-effective, liquid-cooling datacenter technological innovation and other proprietary items that produce significant efficiency with decrease energy usage.

Collectively, even though these packages add to the Scope 3+ mission, each is nevertheless an early exploration, even an experiment. None can remedy the local climate crisis on its very own. In our own goal of reducing carbon emissions by 1.5 gigatons by 2035, we give Scope 3+ not as the solution but as a issue.

For that cause, we really encourage each and every leading organization on Earth to choose a stand with us in a unified struggle to protect our world wide ecosystem together.

Each and every huge change begins at home. For Alibaba, increasing Scope 3+ to its fullest ambitions usually means teaming up with all our partners—merchants, establishments, staff members, and consumers—to lessen our carbon footprint and create bold company improvements and initiatives.

We’re not in this alone—we can’t be. But we want to assistance encourage measures of improve that herald a greener potential for the world.

Platform will provide open-source cell catalogue to better understand brain diseases — ScienceDaily

Salk Institute researchers have produced a new genomic engineering to at the same time analyze the DNA, RNA and chromatin — a mix of DNA and protein — from a one mobile. The approach, which took five a long time to create, is an significant step ahead for huge collaborations where by a number of teams are performing at the same time to classify countless numbers of new cell kinds. The new engineering, revealed in Mobile Genomics on March 9, 2022, will aid streamline analyses.

“This multimodal platform is likely to be beneficial by providing a comprehensive databases that can be applied by the groups seeking to integrate their solitary-modality knowledge,” suggests Joseph Ecker, director of the Genomic Investigation Laboratory at Salk, the Salk Worldwide Council Chair in Genetics and Howard Hughes Healthcare Institute Investigator. “This new data can also notify and manual future cell-style classification.”

Ecker believes this know-how will be essential for substantial-scale endeavours, this sort of as the National Institutes of Health’s Mind Initiative Cell Census Community, which he co-chairs. A important hard work of the Mind Initiative is to build catalogues of mouse and human mind mobile types. This info can then be used to improved fully grasp how the mind grows and develops, as well as the position diverse cell types perform in neurodegenerative health conditions, these kinds of as Alzheimer’s.

Recent solitary-cell technologies will work by extracting either DNA, RNA or chromatin from a cell’s nucleus, and then examining its molecular composition for designs. Nonetheless, this approach destroys the cell in the procedure, necessitating scientists to depend on computational algorithms to evaluate additional than just one of these factors per mobile or to look at the outcomes.

For the new system, named snmCAT-seq, scientists employed biomarkers to tag DNA, RNA and chromatin without having eradicating them from the cell. This allowed the scientists to measure all 3 varieties of molecular info in the identical mobile. The experts then employed this method to recognize 63 mobile varieties in the frontal cortex area of the human brain and benchmarked the efficacy of computational methods for integrating various solitary-cell technologies. The team identified the computational techniques have high accuracy in characterizing broadly described brain-mobile populations but show significant ambiguity in analyzing finely outlined mobile styles, suggesting the requirement to determine cell styles by numerous measurements for more exact classification.

The technology could also be utilized to far better have an understanding of how genes and cells interact to bring about neurodegenerative disorders.

“These ailments can broadly affect quite a few cell kinds. But there could be particular cell populations that are significantly susceptible,” suggests co-to start with creator Chongyuan Luo, assistant professor of human genetics at the David Geffen School of Medication at UCLA. “Genetic investigation has pinpointed the locations of the genome that are appropriate for conditions like Alzheimer’s. We’re giving yet another facts dimension and identifying the mobile styles influenced by these genomic locations.”

As a future phase, the crew ideas to use the new platform to study other locations of the brain, and to look at cells from balanced human brains with those people from brains afflicted by Alzheimer’s and other neurodegenerative diseases.

Researchers from Jawaharlal Nehru Centre for Superior Scientific Study (JNCASR), an autonomous institute of the Department of Science and Technologies, Authorities of India, along with scientists from IISc (India Institute of Science), have demonstrated a noncanonical nucleic acid-based G-quadruplex (GQ) topology targetted reputable conformational polymorphism (GQ-RCP) platform to diagnose Covid-19 clinical samples.

This operate has been posted just lately in the journal ‘ACS Sensors’ and the workforce has also filed a patent for the novel technological know-how.

“The existing do the job shown the 1st GQ-targetted diagnostic system for SARS-CoV-2 in clinical samples, based on a novel system GQ-RCP. This molecular detection system can be integrated into field-deployable isothermal amplification assays with much more dependability and sequence specificity,” the statement mentioned.

The system lays greater emphasis on deciphering and systematic characterisation of a distinctive established of interactions in nucleic acids to attain stable and reliable noncanonical DNA/RNA targets. The RCP-based target validation is a common and modular strategy for the advancement of noncanonical nucleic acid-targeted diagnostic platforms for numerous pathogens, which include bacteria and DNA/RNA viruses.

“RT-q-PCR has been the gold typical for exact detection of SARS-CoV-2 (Covid-19). Between the new improvements on nucleic acid-targeted diagnosis of SARS-CoV-2, the approaches these kinds of as RT RPA and RT-LAMP use common-reason DNA sensing probes. This boosts the propensity of phony-optimistic outcomes arising out of unbiased detection of nonspecific amplification products and solutions. Recognising unique DNA secondary conformations can be a promising answer to accomplish trusted readouts,” the statement observed.

The group has determined and characterised a exclusive G-quadruplex-primarily based concentrate on derived from the 30 kb (kilobytes) genomic landscape of SARS-CoV-2 for specific detection of SARS-CoV-2. Compared with the other trustworthy diagnostic assays in which the existing elementary ideas have been repurposed, this work offers a fully novel system to focus on a unique, unconventional construction specific to the SARS-CoV-2 sequence working with little molecule fluorophores (microscopic molecules).

“The team designed GQ topology focused detection of SARS-CoV-2 derived DNA obtained right after reverse transcription and amplification from genomic RNA in scientific samples. The GQ focused detection was obtained by pH-brought on facile transformation of the amplified double-stranded DNA into secure GQs, which sorts the focus on for detection with impressive selectivity making use of a created fluorescent dye which is a benzobisthiazole-primarily based target-unique change on identified as BTMA,” the assertion explained.

Therefore, this study demonstrates a reliable tactic for fluorogenic organic and natural molecule-based GQ-RCP system to diagnose Covid-19 medical samples and is the initially realistic demonstration of it, it mentioned.

The staff clarifies reliance on targetting strange nucleic acid conformations in pathogens is an thrilling strategy to developing distinct diagnostic assays with reputable study-outs. Molecular probes with superior conformation or sequences for distinct recognition of nucleic acids would relieve the problem in current tactics of doing away with bogus-optimistic detection results.

“We have shown rational tailoring of molecular probes to reach unambiguous focus on recognition and enhance the dependability of detection at a shorter time devoid of the necessity of high-priced RT-q-PCR instrument. This RCP-based platform is quite general and can be very easily adopted for the detection of a variety of DNA/RNA dependent pathogens together with microorganisms and viruses these kinds of as HIV, influenza, HCV, and so on,” said T Govindaraju.
