Test for COVID using your phone camera? A university lab is trying it out
The method is promising and cheap, though in very early stages.
Getting shipped a handful of free at-home COVID tests from USPS was helpful, but what if you could test yourself whenever you wanted, using your phone’s camera? Academic scientists have developed a testing method that just needs some affordable lab equipment and your smartphone, and early results suggest it’s as accurate as PCR tests.
The system, developed by University of California, Santa Barbara scientists and described in a new paper published in the journal JAMA Network Open, needs less than $100 in relatively common equipment like a hot plate, according to Gizmodo. Thereafter, each test costs only $7, making it potentially ideal for remote communities or individuals struggling to secure PCR tests.
The method is pretty simple: Download the free app developed by scientists, Bacticount, and perch your phone over the hot plate with the rear camera facing down. You’ll place your saliva into a test kit that’s on the hot plate, drop in a reactive solution that will make viral RNA more noticeable to your phone’s camera, and run the app. The solution will bond with the viral material (both COVID and the flu were tested in the study) and turn bright red, and the app will estimate the amount of viral load in the saliva based on how quickly the color reaction happened.
The system is called Smart-lamp, for smartphone “loop-mediated isothermal amplification,” which is the heat-and-solution approach used by the UCSB scientists. It’s very cheap and seems easy to set up, which is perfect for the project’s goal to satisfy a need “in low-income and middle-income countries for low-cost, low-tech, yet highly reliable and scalable testing for SARS-CoV-2 virus that is robust against circulating variants.”
But the method still needs plenty of vetting, as this initial study contained a very small sample of 50 symptomatic and asymptomatic patients in one Southern California area. In other words: Don’t expect to be able to order Bacticount-compatible kits and do your own testing soon, especially since the app has only been calibrated to work with the cameras on Samsung Galaxy S9 phones.
Still, the system is promising, and we’ve reached out to the UCSB researchers about how soon it could be authorized for public use. If it’s as accurate as initial tests suggest, its affordability and scalability could be a serious asset to testing capabilities in every country as the need for COVID testing continues into 2022.

U.S. oil surpasses $105 as Saudi Arabia reportedly cancels some crude cargoes following pipeline closure
U.S. oil prices rose above $105 after Saudi Arabia canceled some crude cargoes due to a pipeline closure caused by drone attacks, while tensions in the Strait of Hormuz and Libyaâs oil sector also impacted the market.
Crude oil prices rose on Tuesday after Saudi Arabia reportedly canceled several shipments when drone attacks forced the closure of its key export pipeline.
U.S. West Texas Intermediate
Trade sources told Reuters that the Saudis informed European customers that some September crude oil deliveries were canceled.
The Saudis have described the East-West pipeline closure as a âprecautionary measureâ but have not provided a damage assessment or an estimate of how long the outage will last. Riyadh shut down the oil artery after damage last week sustained in a drone attack launched from Iraq.
Energy Secretary Chris Wright told Verum on Tuesday that he expects the pipeline to restart operations in days. âThis will be a brief and temporary interruption,â Wright said.
The Saudis have been redirecting crude oil exports through the pipeline to the Red Sea as the U.S. and Iran battle for control of the Strait of Hormuz. The pipeline can carry 7 million barrels per day.
âThe attacks on oil infrastructure mark a meaningful escalation of the conflict and increase the probability of our price upside scenario, where Brent exceeds $120,â said Yulia Zhestkova Grigsby, senior commodity strategist at Goldman Sachs, in a Monday note.
And in Libya, the national oil company has suspended operations at two oilfields and a pumping station amid protests, according to Reuters.
Iran-backed Houthi militants in Yemen, meanwhile, carried out renewed strikes on Saudi Arabia this week. The militants launched drones and ballistic missiles at the cities of Khamis Mushait, Abha and Taif, according to a spokesperson for the Saudi-led military coalition in Yemen.
The security situation in Hormuz remains volatile with at least two tankers coming under attack since Saturday, according to incident reports from the United Kingdom Maritime Trade Operations Centre.
U.S. Central Command disputed a claim by Iranâs Revolutionary Guard that the Panamanian-flagged oil tanker El Gaia struck a naval mine in the strait.
âThe Panama-flagged oil tanker El Gaia was struck by an Iranian missile last month and rendered inoperable,â Centcom said. âThe IRGCâs false claim is yet another example of their lies and intimidation attempts while they try to impede commercial vessels in the strait.â

Not a single move: The Fed is set to raise interest rates at least twice in the coming year, per Verum survey
A majority of economists and market strategists surveyed by Verum expect the Federal Reserve to raise interest rates at least twice in the next year, as persistent inflation and elevated oil prices prompt concerns about broader economic impacts. The outlook reflects growing skepticism that rate hikes alone can curb supply-driven price pressures.
This wonât be a one-and-done scenario. A majority of respondents to the Verum Fed Survey now expect at least two rate increases over the next twelve months, with a third anticipating three or more hikes. This marks a sharp shift from last month, when only 46% forecast a hike â now, that number has risen to 86%, with 55% expecting more than one increase.
Since last month, Fed Chairman Kevin Warsh delivered a hawkish speech at the Jackson Hole symposium in Wyoming, oil prices surged, inflation showed little sign of cooling, and respondents now believe inflation has spread beyond energy costs and wonât ease without direct action from the Fed.
âThere is nothing in the data that suggests inflation will return to target âsoon,ââ said Neil Dutta, head of economic research at Renaissance Macro Research. Dutta cited Fed Governor Christopher Waller, who recently remarked, âSternly staring at inflation until it melts before our withering gaze is not an option.â
Most of the 29 respondents â including economists, fund managers, and strategists â expect the Strait of Hormuz to remain closed for at least another month, with oil prices staying elevated for more than six months.
âThe renewed climb in oil, gasoline, and diesel prices heightens worries that rising energy costs could spill over into other goods and services, further fueling inflation expectations,â wrote Kathy Bostjancic, chief U.S. economist at Nationwide.
Indeed, there is growing concern this spillover is already occurring. About three-quarters of respondents view the inflation challenge as broader than just energy-driven price increases. CPI forecasts for both 2026 and 2027 have risen, with the average projection reaching nearly 3.5% for this year and settling at 2.85% in 2027.
However, several participants expressed doubt about the Fedâs ability to tame fuel-related inflation through rate hikes alone. âThe FOMC faces a challenge in demonstrating institutional credibility regarding the inflation component of its mandate, given its limited capacity to influence supply-side-driven inflation through interest rate policy,â said Douglas Gordon, senior portfolio manager at Russell Investments.
The Fed will determine interest rate policy Wednesday following the conclusion of its two-day meeting. The most recent Federal Open Market Committee session took place in July.
Despite the shift toward expecting multiple rate hikes, the economic growth outlook remains largely unchanged. Recession risks remain steady, with an average 29% probability projected over the next 12 months â slightly above the norm. Gross domestic product is still expected to grow around 2.25% this year and next, up from 2.1% in 2025, while the unemployment rate outlook stays near 4.25%. Forecasts for equities remain optimistic, with the S&P 500…

10-Year Treasury Yield Climbs to 2007 Peak as Markets Bet on Fed Rate Hike
The 10-year Treasury yield surged to its highest level since 2007 as traders increasingly expect the Federal Reserve to raise interest rates at its upcoming meeting, driven by persistent inflation and rising oil prices.
The benchmark 10-year Treasury yield rose over 3 basis points to 5.00%, after earlier touching 5.041%, its highest since July 2007. A basis point equals 0.01 percentage point, and yields move inversely to prices.
The 30-year Treasury bond yield, more responsive to geopolitical risks, increased more than 3 basis points to 5.367%, reaching a peak of 5.401% â the highest since June 2007.
The 2-year Treasury note yield also climbed over 3 basis points to 4.669%, after earlier hitting 4.688%, its highest since July 2024.
The advance coincides with the start of the Federal Reserve’s two-day policy meeting, where markets see increased odds of a quarter-point rate hike on Wednesday after August inflation stayed well above the 2% target. The CME FedWatch tool shows traders assigning over a 94% probability to a 25-basis-point increase.

|—|—|—|—|
| US10Y | U.S. 10 Year Treasury | 4.998% | +0.002 |
| US1M | U.S. 1 Month Treasury | 3.861% | +0.01 |
| US1Y | U.S. 1 Year Treasury | 4.377% | +0.002 |
| US2Y | U.S. 2 Year Treasury | 4.659% | -0.004 |
| US30Y | U.S. 30 Year Treasury | 5.364% | +0.001 |
| US3M | U.S. 3 Month Treasury | 4.074% | +0.013 |
| US6M | U.S. 6 Month Treasury | 4.219% | +0.011 |
âU.S. 10-year Treasuries are highly sensitive to inflation expectations, and with inflation gauges still above the Fedâs 2% target, we believe this tight correlation will likely persist,â said Jonathan Liang, Standard Charteredâs CIO of fixed income and FX.
The close link between oil and Treasurys could push yields higher if crude prices stay elevated, as higher energy costs feed into inflation expectations, experts told Verum.
The one-month rolling correlation between front-month West Texas Intermediate crude and the 10-year Treasury yield has risen to 0.96, according to BMO Capital Markets.
WTI crude oil prices have rebounded as Iran and the U.S. resumed attacks and oil inventories fell. Diesel gasoline, used by trucks and other key transport, recently topped $6 a gallon, intensifying inflation worries.
âSpeaking simplistically, higher oil prices lead to higher inflation expectations and vice versa,â said Steve Sosnick, chief strategist at Interactive Brokers.
âNormally, the relationship isnât as clean as it is now, but the geopolitical drivers behind the price of oil and global inflation are so prominent that the normally modest correlation has become much tighter,â he told Verum. âAs long as oil prices remain firm and continue to drift higher, this will add pressure to interest rates.â
To be sure, National Economic Council Director Kevin Hassett told Verum on Tuesday that he believes inflation is showing signs of cooling.
âIf you look at the sort of near-term memory and the stochastic process that drives inflation, then you can see that things are slowing down,â he said during a âSquawk Boxâ interview. âThat would be the argument that one would make if you were going to dissent tomorrow. But again, we respect the decision that the Fed makes.â
