Hackers heated supermarket freezers in at least 11 countries

There are many products for hair thinning on the market, but they don’t all deliver on their promises. OneSkin’s OS-01 HAIR SCALP SERUM is backed by clinically validated longevity science, and proven to improve thickness and density with consistent use. 

Treatments like DHT blockers address pattern thinning, and minoxidil increases blood flow to the scalp. But OS-01 HAIR is the only scalp formula to specifically address the dysfunctional senescent cells behind age-related hair thinning.

Powered by OneSkin’s proprietary OS-01 Peptide™, OS-01 HAIR SCALP SERUM targets the spread of senescent cells at the scalp, creating the optimal conditions for visibly fuller, healthier-looking hair.

Address hair thinning where it begins. Make OneSkin’s OS-01 HAIR part of your longevity stack, and optimize your hair health routine.

The Ready Brief #244

Practical preparedness for uncertain times

This week's lead is about food that spoiled because someone changed a temperature setting from far away. Fuel works the same way: a stored resource quietly loses value if nobody checks it. So today's brief covers gasoline, which Maine's environmental agency says should not sit more than 30 days without a stabilizer. Check yours before you need it.

Gasoline Storage and Rotation

Gasoline runs cars, generators, chainsaws and mowers. A reserve helps during an outage, but only if the fuel still works when you need it.

Maine's Department of Environmental Protection advises against storing gasoline more than 30 days unless a stabilizer has been added. Most US gasoline contains about 10% ethanol, according to the EIA, and ethanol attracts water. Maine DEP notes that this can cause phase separation, where water and ethanol settle at the bottom and gasoline floats above, which can stop small engines from running.

STA-BIL says its fuel stabilizer keeps fuel fresh for up to 24 months and works in ethanol and non-ethanol gasoline. Add it at fill-up, following the label. Stabilizer helps prevent degradation, but it does not restore fuel that has already gone bad. For ethanol blends, Maine DEP suggests a stabilizer labeled as compatible with ethanol gasoline.

Use an approved safety can. Maine DEP says to use UL-approved containers, red for gasoline, with a spout that pours without spilling. Do not use glass jars or plastic milk jugs, which can break or deteriorate. If fuel will sit longer than a month, Maine DEP says to keep the container 95% full, which leaves room for expansion and limits air space that causes condensation.

Store cans in a well-ventilated shed or detached garage, out of children's reach and away from pilot lights, furnaces and other ignition sources. Maine DEP also says to keep fuel as far as possible from your drinking water well, and downslope from it.

Buy only what you need. Maine DEP advises this, and local fire codes can limit how much gasoline a household may keep, so check yours.

Rotate on a schedule. Every month or two, use the stored fuel in your car and refill the can with fresh, stabilized gasoline. Write the fill date on a piece of tape on each can so you know its age.

Ethanol-free gasoline avoids the water-absorption problem. Pure-gas.org lists stations that sell it in the US and Canada.

Check your gas cans.

Find every gas container you own. Look for a fill date and smell the fuel. If it smells sour or like varnish, or you can see water or layers in it, take it to a household hazardous waste site rather than pouring it into your car. If there is no date, write one on tape today. It takes about five minutes.

False bomb threats hit at least seven flights and a cruise ship across Europe

Officials said every threat received Tuesday was false. At least seven flights were targeted, four of them on Ryanair, with others on Wizz Air, SAS and LOT, and the airports involved included Warsaw, Rome, Sofia, Murcia and Heathrow. Greece's coast guard evacuated the cruise ship Crown Iris, carrying about 1,500 people, off Syros, and no device was found. All planes landed safely. No one has claimed responsibility. Analyst Rhys Jones of Osprey Flight Solutions called seven confirmed threats in one day "exceptional." If you fly in Europe soon, allow extra time and keep a charger and your itinerary in your carry-on.

Our takeaway (not a quote from Krebs): gasoline is not a store-and-forget item. Date it, stabilize it, rotate it, and check it on a schedule, the same way you would a food pantry.

Hackers heated supermarket freezers in at least 11 European countries

Hackers raised the temperature of refrigeration systems in supermarkets on Nov 2 and 3, according to Al Jazeera. Monday's attacks reached at least nine EU countries, including Belgium, Ireland, Italy and Sweden. On Tuesday, four stores in Germany and six in Romania were hit. Belgian federal prosecutors opened an investigation, and a Sicilian Coop director said, "We had to throw away everything." Italy's government called the impact limited, and no one has claimed responsibility. The attacks follow an October wave that hit hundreds of French supermarkets. Danfoss, whose controllers were targeted, advised that they not be directly reachable from the internet. For a household, the practical point is a pantry that does not depend on the cold chain: shelf-stable food covers the gap while a store restocks.

SureCan 5-Gallon Gasoline Type II Safety Can

We recommend a Type II safety can for anyone who refuels a generator by hand. According to Blain's Farm & Fleet, the SureCan has a flexible spout that rotates 180 degrees, a thumb trigger, and a self-venting design, so you pour at an angle instead of lifting the full can.

It costs more than a basic can: Blain's Farm & Fleet and Bass Pro both listed it at $76.99 on Nov 4. We have not tested it ourselves, so treat this as a pick based on the manufacturer's listed features, not a review.

Overrated: Stockpiling large quantities of gasoline. Maine DEP advises buying only what you need, and local fire codes can cap how much a household may store.

Underrated: Keeping your car's tank at least half full. It is a reserve that needs no extra containers, and the fuel turns over with normal driving.
