High-Tech Smell Sensors Aim to Sniff Out Disease, Explosives—and Even Moods
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.”

When purchasing exercise clothing, the aspect of support is often overlooked. Sportswear companies tend to prioritise features such as moisture-wicking materials and convenient pockets. However, we believe that support is a crucial aspect of dressing for workouts, as it ensures both comfort and optimal performance. Support can be seen as the intersection of sportswear and shapewear. Therefore, it is essential to understand the significance of appropriate support during physical activity and know where to find it.
The Shapewear Crossover
Supportive sportswear primarily functions through gentle compression. It maintains stability and keeps your body secure while you engage in physical activity. Common characteristics between Standard shapewear and sports bras can be found. Both utilise specialised, flexible materials to offer body support. They are also designed with minimal seams to prevent discomfort and ensure discreteness. Additionally, the emphasis on comfort remains consistent for both types of apparel. As a result, similar principles apply when it comes to providing optimal body support.
What kind of support should your athletic apparel provide?
When engaging in physical activities, it is important to wear clothing that provides stability, regardless of the intensity. Whether you are running a marathon or practising yoga, your Sports bras and briefs should not cause any discomfort or irritation. In this article, we will explore the areas of the body that require support from sportswear.
Breast support
A sports bra is essential for any physical activity, regardless of intensity. It serves as the ultimate supportive sportswear, providing both comfort and stability. By minimizing excessive movement, it helps prevent discomfort in the breast and back areas. With the multitude of options available, finding the perfect sports bra style depends on factors such as your breast size, the type of sport you engage in, and your preferred method of wearing and removing it.
Back support
If you’ve ever dealt with back pain, you understand the significance of a well-fitting bra. A sports bra that offers adequate support helps minimize the strain on your muscles and ligaments, preventing discomfort and soreness in your back. Additionally, it alleviates upper back and shoulder pain commonly associated with the weight of larger breasts.
Tummy support
Those who possess knowledge on the matter may opt to provide support to their waist and stomach by wearing sports underwear or leggings. Both options are equally effective. It is advisable to seek out high-waisted compression garments with a wide waistband, as they contribute to the stability and strength of your torso, which is vital in preventing injuries. By promoting stability and offering support to the abdomen, these garments also aid in preventing chafing and can boost your confidence, allowing you to elevate your performance.
In recent years we’ve definitely seen a shift in the fashion industry, with influencers and celebrities placing pressure on the high street to make plus-size fashion more accessible for all. Nowadays, Sportswear is highly demanding as demonstrated by plus size UK influencers.
The advantages of wearing supportive sportswear
The support provided by activewear has a tangible influence on your sports performance and how your body reacts to exercise. It’s no wonder that many women opt for activewear as their everyday clothing choice.
Posture
The incorporation of compression panels in clothing such as high-waisted underwear or leggings can enhance your posture. Maintaining a strong and stable posture is crucial during physical activities to prevent injuries. Whether you engage in sports like tennis, running, or weightlifting, having adequate support around your torso can significantly benefit you.
Comfort
The crucial aspect of effective sportswear is its ability to provide comfort. It is important to ensure that your sportswear does not constrict your breathing. To find comfortable and supportive garments, opt for those with extended panels made of lightweight fabrics that wick away moisture. These fabrics are not only lightweight but also provide support to your body while minimising the risk of chafing. Additionally, an increasing number of garments are being designed without hems, allowing them to sit smoothly against your skin without causing any discomfort.
Performance
Compression is commonly utilised in shapewear to create a desired figure, but in the context of sportswear, it can actually improve your performance. Whether it’s in the form of socks or leggings, compression technology promotes better blood circulation to targeted areas like your legs. This increased blood flow intensifies your exercise routine and contributes to faster recovery.
The finest athletic attire should not only prioritise fashion and technology. Its primary function is to provide stability to your core, enabling you to engage in activities comfortably and confidently. This underscores the significance of support, which is crucial not just during physical exertion but also in day-to-day life.

Exploring Alternative Sentencing Options: Understanding the Potential for No Jail Time in 2nd Offense DWI Cases in Texas:
While Texas has some of the most drunk drivers in the country, the state also has some of the strictest DWI penalties. Despite how common a Texas DWI and 2nd DWI can be (with over 30% of DWI convicts reoffending), a 2nd DWI conviction will land you at least 72 hours in county jail and possibly even a year. Although many will agree that the punishment fits the crime, a 2nd DWI charge can be a telltale sign of alcohol addiction, and can often require rehabilitation that a jail sentence cannot offer. Luckily enough, there are several ways you can avoid a conviction for a 2nd DWI in Texas to receive no jail time and focus on your rehabilitation.
An Expert DWI Attorney:
Since mandatory jail time can only be avoided by avoiding conviction, a skilled DWI attorney is crucial to any option you explore. A 2nd DWI charge requires the same amount of evidence as a 1st DWI charge, and can often be defended with the same tactics. Depending on the circumstances of your case, a DWI attorney may be able to scrutinize a field sobriety test, the administration of a breathalyzer test, or the constitutionality of a traffic stop. Always inquire about the potential for a successful defense before you set your mind on other options, as dismissal or acquittal is the only way to circumvent all penalties of a 2nd DWI in Texas no jail time. If an expert attorney determines that your case won’t fare well at trial they can petition for probation or a DWI court to proceed over your case, or negotiate a plea for you.
DWI Court:
Many of Texas’ major cities offer a DWI court program as a way to avoid jail for DWI 2nd offenders or defendants who show signs of alcoholism. DWI court is similar to probation but heavily emphasizes rehabilitation. A program will typically involve common aspects of community supervision, routine attendance at outpatient programs, and meetings between you, a judge, a probation officer, and a counselor. If you do not abide by the court’s rules or mandatory programs your case can go back to court and you will likely go to jail. A DWI court program is at least a year, but the length and regimen can be augmented depending on a defendant’s progress. Upon a judge “graduating” you from DWI court your sentence will be fulfilled. DWI court not only allows you to avoid jail time but is known to reduce DWI recidivism rates by as much as 12%.
Plea Bargain:
With Texas’ criminal justice system being notoriously arduous, nearly 30% of all DWIs are reduced to lesser charges to avoid the hassle of a trial. In cases without aggravating factors such as an enhanced blood alcohol concentration, a child passenger, or an accident, a 2nd DWI charge can be bargained down to a minimum sentence or reduced charges. To be considered for a plea deal, a defendant will usually have to show personal growth and remorse. This is typically done by issuing a statement to the court, installing an ignition interlock in your vehicle, or attending DWI education courses or outpatient. If you plea to a minimum sentence you will likely still face 72 hours in jail and probation. While it’s uncommon for a 2nd DWI plea deal in Texas to receive no jail time, this is not impossible if your charges are reduced to reckless driving or obstruction of a highway.
Don’t Drink and Drive:
72 hours in jail is considered the mandatory minimum sentence for a 2nd DWI conviction and those facing charges are unlikely to see no jail time. The only guaranteed way to avoid jail is to avoid drinking and driving. With a drunk driving fatality occurring every 8.5 hours in Texas and over 10% of Texans reporting involvement in a drunk driving crash sometime in their lives, don’t fall under the impression that you are immune to the consequences of a DWI. Always make sure that you have a designated driver or extra money for an Uber when you go out drinking, it can save someone’s life and protect your future.
