We live in a world of odors—chemical signals that contain valuable data about our health, the environment and even personal choices like which foods, perfumes and beverages we enjoy. Despite decades of research and development, however, this aromatic information has remained mostly untapped.
But now scientists and entrepreneurs are redoubling their efforts to recreate the sense of smell in compact devices that detect and analyze odors similar to the way cameras now recognize our faces and microphones our words. In pursuit of these high-tech devices–which could use odors to detect disease like cancer or Covid-19, locate hidden explosives or decipher our moods and behaviors—some companies are leveraging advances in synthetic biology and genetic engineering. Others are harnessing advances in artificial intelligence.
utely a growing field,” says Andreas Mershin, an odor-sensor researcher at the Massachusetts Institute of Technology. “We’re recognizing that there’s a whole world of molecules we’re blind to.” He calls the field an “unexplored goldmine.”
The quest to build better olfactory sensors is a challenging one because odors are made up of many different chemicals and because animals’ olfactory receptors—specialized cells in the nose that recognize odor molecules—are remarkably diverse. Humans have three types of receptors for color vision, for instance, but hundreds of different olfactory receptors.
Among the most futuristic devices are those that incorporate living cells engineered to react to specific odor components. Koniku Inc., a startup in San Rafael, Calif., is now using bioengineered nerve cells as the basis for sensors capable of recognizing the subtle odors of explosives. The cells contain proteins designed to detect so-called volatile organic compounds, carbon-containing substances that seep into the air from a range of sources, including food, paints, beverages, bodies and unexploded bombs.
“We design smell cyborgs,” says Osh Agabi, founder and chief executive of the firm. He says the firm is working with Airbus Americas to develop sensors for use at airports to detect packages and luggage containing explosives. The goal is not to replace bomb-sniffing dogs and other security measures now in use but to augment them, according to Bruce Coole, head of aviation-security programs at Airbus Americas.
In recent tests at San Francisco International Airport, a prototype of Koniku’s bomb-sniffing device identified pieces of planted luggage known to contain explosives with an accuracy of 97%, according to Dr. Agabi. In separate tests, Koniku’s sensors matched trained dogs’ ability to detect explosives, he says, adding that the company is also developing sensors for use in healthcare and other industries.
“When you look at the scale of how many compounds or how many smells are impacting human life that are yet to be cataloged, we have barely scratched the surface,” Dr. Agabi says.
Aromyx Corp., a startup in Mountain View, Calif., is also using cells to create odor sensors. But rather than selling devices, it offers food and wine producers a lab-based service to help them better understand the specific odor molecules that drive consumer preferences. Company workers pair consumer-survey data on people’s likes and dislikes with how Aromyx’s bioengineered odor-detecting cells react to certain odor molecules to come up with preference profiles.
“The value is not in the sensor, but in the data,” says Josh Silverman, Aromyx’s chief executive.
MIT’s Dr. Mershin is focusing on medical applications of olfaction technology. Inspired by dogs that have demonstrated an ability to sniff out malignancies in humans, he’s working on an artificial-intelligence odor-detection system to detect prostate cancer.
In 2021, Dr. Mershin’s team published results showing that their system matched trained dogs’ ability to detect prostate cancer in the urine of patients with the disease. Since then the team has increased the software’s accuracy to more than 90%, Dr. Mershin says, adding that the system is more reliable than the well-known prostate-specific antigen (PSA) blood test, which can lead to false-positive diagnoses. Only 25% of men who undergo a prostate biopsy following a suspicious PSA finding are later found to have cancer,
Olfaction experts warn that a series of scientific and technical challenges must be overcome before high-tech odor detectors are ready for broad penetration into the marketplace. For systems that use living cells, it will be important to monitor how often devices need to be replaced and how accuracy stacks up over long time frames, they say.
“The idea is great. It’s the implementation that’s the problem,” says Nathan Lewis, a chemist and olfaction-sensor developer at the California Institute of Technology.
Scientists and data rights experts say the emergence of sophisticated molecular surveillance—for example. turning cell phones into what some experts call “smell phones” capable of spotting medical conditions— raises thorny questions of privacy. After all, odors our bodies constantly emit contain clues about our health and personal choices, including the products we use and the foods we eat as well as our drinking and smoking habits and more. The collection and analysis of human olfactory data could affect some insurance coverage, for example, as well as employment, according to legal experts.
“We’re not prepared for the implications,” says David Carroll, an associate professor of media design at the Parsons School of Design and a data-rights activist. “It’s going to bring up deep and profound ethical quandaries.”

How to Find an Obituary for a Specific Person
As part of your family tree or ancestry research, you may need to find the obituary of a particular person. This article provides a list of resources to help find the obituary of a particular person.
Obituaries are one of the most important sources of information genealogists look for when looking for clues related to the life of their ancestors. What many may not know is that the practice of announcing death in this way dates back to 59 BC.
Roman newspapers inscribed in metal or stone, known as the Acta Diurna (Daily Events), are published in important places in Rome. It features celebrity births and deaths, as well as general gossip about important people in the city.
In 1439, the printing press was invented, and with the advent of newspapers, the practice of announcing prominent deaths continued.This has survived and is still a common practice.
So why do genealogies need obituaries, and more importantly
, how do you find the obituaries you need for your research?
Importance of obituaries
relatives and friends
Those with aging parents or who lived with grandparents may have sat and read the local newspaper to see if anyone they knew had died. As we grow older, we feel a morbid fascination with our own mortality, and as a result, we become fascinated by the people we meet and those who are close to our own age.
An obituary is an opportunity for families to let people they don’t know know that a loved one has died. In many cases, this allows family members to let people know when the funeral will be held, and old friends to attend and offer their condolences.
Obituaries serve an important social function. Because bereaved families don’t have to spend time grieving connecting with everyone the deceased loved one may have known.
Although obituaries are very important to genealogists, they are technically not considered definitive documentary evidence. Searching for ancestors in obituaries can help you find important information such as:
Religion and Church Affiliation
date of birth and place of birth
place of death and date of death
important biographical information
The family information provided in the obituary helps distinguish between the two of her namesakes in official documents. Knowing the names of siblings and parents makes it easier to determine a person’s accurate census record.
As with any mystery, there may be many small clues here to help you find the truth and the documents that support it. should always be taken as clues until further evidence is documented.
Cost increases faced with end of Adjusted Right to Rent checks
Rental agents are taking significant steps to comply with rental eligibility checks as the system allowing for coordinated checks (for example via Zoom calls and copies of documents) will end in the UK on 30 September of 2022. We are facing increasing costs.
From October 1, 2022, agents responsible for reapplying for tenants and rent checks will need to review their processes to be ready to return to manual in-person checks (this may be because someone who qualifies as a UK resident you will still be admitted if you present a valid ID). and Irish citizens), or register with one of the proptech service providers accredited by the UK government as a Digital Identity Service Provider (IDSP). Foreign checks must be processed through the Ministry of the Interior’s Sharecode system, to which agents have free access.
The change comes at the same time that agencies will have to deal with rising energy bills and rising staff retention costs by maintaining competitive compensation packages.
IDSP cost for British and Irish citizens
With the announcement of the first IDSP under the UK’s digital identity and attribute trust framework, agents need to be aware of and prepare for the upcoming changes. With the promulgation of the Tenant Fees Act 2019, the costs associated with the delivery of checks for the right to rent have not changed and cannot be passed on to applicants.
Coordinated checks were introduced as part of COVID-19 measures to reduce face-to-face contact and have been expanded as the Home Office works to implement a robust digital solution for national checks in the UK and Ireland. If an agent wishes to provide digital checks to people with ID cards in the UK and Ireland, once adjusted rental eligibility verification is complete, the agent will need to register with an ID service provider who will incur a fee for the service. Alternatively, agents can provide a manual verification in person if the applicant provides a suitable British or Irish ID. If an agent chooses to use IDSPs, they must take into account UK and Irish citizens who choose to verify their identity offline and must not discriminate on that basis.
Digital verifications for foreigners can be done easily and at no external cost by verifying through the home office system in real time using the common digital code and date of birth provided by the applicant.
If the agency’s system relies primarily on in-person reviews, consider the need for additional time and resources to schedule appointments for applicant reviews (and follow-up reviews of submitters, subject to time constraints). status) and the associated time change.
Keeping track of rent checks is more important than ever
Propertymark members notify the Home Office to establish a “legal excuse” for agents to provide statutory audit information if they are unable to obtain a foreign rent check again during the rental period. against late and/or civil penalties.
The Rental Law Code of Practice is ambiguous about liability for civil penalties when agents use IDSPs. The ultimate responsibility for verification rests with the landlord or designated rental agent. Therefore, the use of a UK government accredited IDSP does not eliminate all risks of civil penalties for landlords or designated rental agents when investigated by immigration authorities.
The reintroduction of personal checks coincided with seasonal changes in the incidence of COVID, the impact of which is unknown.
Since it was first introduced under immigration law in 2014, the work required for agents to complete rent checks in the UK has increased dramatically and there are now over 100 pages of instructions for agents to understand. years. The Rent Payments Act of 2019 forced agents to incur higher costs in this area.
A period of additional requirements is coming, whether agents continue to conduct in-person rental checks during application and follow-up or use one of our approved IDSP providers. This is a particular problem given the heightened scrutiny of students who are British citizens from the academic year onwards.
