Vladimir Putin indirectly justified Russia’s war of aggression once morest Ukraine with a more than idiosyncratic interpretation of history: Tsar Peter the Great (1672-1725) did not conquer the area around today’s metropolis of Saint Petersburg from Sweden in the Great Northern War, but “won it back”. In fact, the city was founded in 1703 on swampy land near the sea to enforce Russia’s claim for access to the Baltic Sea. Historically, the Baltic States have never been Slavic, which is why its comparison with the “repatriation” of Ukraine seems questionable in several ways.

Ringing or ringing in the ears (tinnitus) are sounds that originate in the ear and not in the environment. Although it is a symptom and not a specific disease.
Specifically, it is usually caused by an underlying condition, such as age-related hearing loss, a circulatory system disorder, or an injury to the ear, depending on the Mayo Clinic.
David M. Kaylie, a physician at Duke University Medical Center, points out that the noise perceived by people with tinnitus It can be a hissing, buzzing, tinkling, or roaring sound. and is often associated with hearing loss. In some cases, people hear more complex sounds that can vary at different times.
Symptoms
Tinnitus is usually described as ringing in the ears, even though there is no external sound source. However, tinnitus can also cause other types of imaginary noises in the ears:
- Sisees.
- murmurs.
- tinnitus.
- roars.
- Clicks.
The diseases in which they can occur are:
- Auditory system tumors.
- Hearing loss (deafness or hearing loss).
- Otitis.
- Earwax plugs.
Causes
Head or neck injuries
- A head or neck injury can affect the inner ear, brain function linked to hearing, and the auditory nerves.
- These lesions usually cause tinnitus in only one ear.
Medicines
- Ototoxic drugs: acetylsalicylic acid, quinine and some antibiotics, according to the Clinic of the University of Navarra.
- In general, the higher the doses of these medications, the worse the tinnitus.
hearing loss
- There are small, delicate hair cells in the inner ear (cochlea) that move when sound waves arrive. This movement causes electrical signals to be sent through the nerve from the ear to the brain (auditory nerve).
- The brain interprets these signals as sounds, and if the hearing cilia in the inner ear bend or break, they can cause electrical impulses to “leak” into the brain for no reason, which can cause tinnitus.
Ear infection or blockage of the ear canal
- The ear canals can become blocked if fluid (ear infection), dirt or wax, or other foreign material builds up.
- A blockage can change the pressure in the ear and cause tinnitus.
Tinnitus usually causes a noise that originates in the blood vessels near the ear. In these cases, the sound is heard with each heartbeat (pulsatile). The causes, according to the portal specialized in health MSD Manuals son:
- Certain middle ear tumors that have abundant blood vessels.
- A malformation of the blood vessels in the membrane that covers the brain.
- Turbulent flow through the carotid artery or jugular vein.
Prevention:
- Take care of cardiovascular health: Exercising regularly, eating right, and taking other steps to keep your blood vessels healthy can help prevent tinnitus linked to blood vessel disorders and obesity.
- Limit the consumption of alcohol, caffeine and nicotine: these substances, if consumed in excess, can affect blood flow and contribute to tinnitus.
- Use hearing protection: Over time, exposure to loud sounds can damage the nerves in your ears, leading to hearing loss and tinnitus. It is recommended to try to limit exposure to loud noises. Also wear hearing protection to protect your ears.
- Decrease the volume: Long-term exposure to amplified music without hearing protection or listening to music at high volume with headphones can cause tinnitus or hearing loss.
Historic discovery: Global worm-eating plastic worm discovered
An end to the world’s worries regarding how to dispose of plastic waste. Scientists have discovered a worm that eats plastic. Researchers at the Australian University of Queensland have discovered a species of worm that feeds on polystyrene, which might revolutionize plastic recycling.
Environmental damage caused by plastics that do not dissolve in the soil and do not burn is not a minor headache for mankind. Scientists say the discovery of plastic-eating organisms in a state where even the ocean is full of non-recyclable plastics is considered a major revolution.
Scientists at the university have discovered that the larvae of Sophobas morio Darkling beetles have bacterial gut enzymes for these superworms. Enzymes that feed on plastic are found in large quantities in their bodies.
This was discovered in a three – week experiment using superworms by Chris Ring and his team from the UK’s School of Chemistry and Molecular Biosciences. The experiment was performed by giving different diets to different groups. A few worms were given polystyrene. Others were given bran. The rest were not given any food.
He said that he survived by eating polythene and was found to be in good health. Rinke said. Rinke added that super worms are like mini recycling plants and they eat plastic well. The research team found several enzymes in the gut of the super worm. Their gut has the ability to destroy polystyrene and styrene. The above are the plastics used in takeaway containers and other plastic items such as insulation and car parts. They have the ability to digest it.
At the same time, these findings explain that although plastics are a favorite food, it is not a nutritious or healthy food and can affect their health.
Earlier, scientists had discovered worms inside the plastic. Waxworms, commonly found in hives, have been found to be the first to feed on plastic. They can be easily eaten even by polyethylene, which is usually difficult to cut. Researchers believe that they can eat plastic faster because of special enzymes in their saliva. Through these, they easily attack the plastic chemical bonds. That is, it is assumed that the wax in the hive will be digested in the same way as the plastic.
Federica Bertocch, a biologist and amateur beekeeper, discovered the ability of the wax worm to eat plastic while cleaning her hive. When they were temporarily placed in a plastic shopping bag, it turned out that they were eating the bag. Subsequent experiments at the University of Cambridge proved this to be true. Within 12 hours, 92 mg of plastic was completely eaten away.
Previous experiments with bacteria have shown that they can eat only 0.13 mg of plastic. It took 24 hours. Researchers at the Institute of Biomedicine and Biotechnology of Cantabria also collaborated with researchers at Cambridge for this experiment. They showed by spectroscopic analysis that these worms might break the chemical bonds in plastic.

U.S. inflation intensifies, the market estimates that the probability of the Fed raising interest rates by 3 yards in July is 50% | Anue Juheng – US Stocks
U.S. stubbornly high inflation has increased bets that the Federal Reserve (Fed) needs to actively raise interest rates to cool price pressures. The policy rate is expected to rise to 3% by the end of the year.
According to a report released by the U.S. Department of Labor on Friday (10th), rising food prices and record gasoline prices pushed the consumer price index (CPI) to 8.6% year-on-year in May, higher than market expectations of 8.3%. Inflated any hopes that had peaked last month.
The annual growth rate of the core CPI, which excludes energy and food prices, reached 6% in May. Although it was down from the previous value of 6.2%, it was still higher than the expected 5.9%, and it was also far from the slowing rate that Fed Chairman Powell said. “Clear and convincing” signs of cooling in price pressures are needed before interest rates.
At the same time, the U.S. consumer confidence index for June released on the same day fell to a record low, and consumers were worried regarding the outlook for inflation.
Greg McBride, chief financial analyst at Bankrate, said the view that inflation has peaked is over, and any hope that the Fed will slow down its rate hikes following its June and July meetings now looks unlikely.
Fed officials have all but committed to raising rates by two yards (50 basis points) each at their next meetings in June and July. Interest rate futures traders see a 2-yard rate hike as the most likely outcome of the Fed’s meeting next week, but current expectations are regarding a 20 percent chance of a 2-yard rate hike this month.
The odds of the Fed raising rates by 3 yards (75 basis points) in July are close to 50%, according to CME Group FedWatch data.
Elsewhere, the 2-year yield, the Fed’s benchmark for interest rate policy, posted its biggest gain in four months, rising above 3 percent for the first time since 2008. Analysts at Barclays said on Friday that the Fed has good reason to announce a larger-than-expected rate hike at its meeting next week.
The latest inflation data may also allow the Fed to raise interest rates by two yards during the September meeting, or even longer, to fight inflation. Futures linked to Fed rates show traders are now betting the Fed will raise rates by at least 2 yards by September, and possibly more. Futures reflected market expectations that the policy rate would be in a range of 3% to 3.25% by the end of the year.
The latest inflation report also makes it harder for the Fed to control inflation without destroying the job market and causing a recession.
Peter Cardillo, chief market economist at Spartan Capital Securities, said the May CPI data was too bad, predicting that the U.S. will enter a recession in the fourth quarter of this year, which is confirmed in the second quarter of 2023.
