Under an electron microscope, Naegleria fowleri can appear highly irregular, with a rough surface and structures such as pseudopodia, filopodia, and other projections. Some microscopy images may also create the visual impression of a distorted face, although the “eyes and mouth” appearance is simply a resemblance perceived in the image.

AI Has Designed More Than a Dozen New Viruses That Infect Bacteria

Scientists have used an artificial intelligence model called Evo to create more than a dozen previously unknown bacteriophages, viruses that infect bacteria.

Evo is a biological language model trained to recognize patterns in DNA. Similar to how a language model predicts the next word in a sentence, Evo predicts which genetic letters, A, C, G, or T, should come next in a DNA sequence.

Researchers trained the system on thousands of bacteriophage genomes and instructed it to generate new versions of ΦX174, a small virus that infects E. coli.

The team then chemically synthesized 285 AI generated genomes and tested them. Sixteen successfully developed into functional viruses capable of infecting E. coli, reproducing inside the bacteria, and killing the infected cells.

These viruses were not simply copies of naturally occurring viruses. Their genomes contained between 67 and 392 mutations compared with their closest known relatives. Thirteen also contained genetic changes that had never been observed in known natural sequences. One was sufficiently different that it could potentially represent a new viral species.

The researchers chose ΦX174 because of its place in genetic science. In 1977, it became the first organism to have its entire genome sequenced. In 2003, it became the first genome assembled completely from synthetic DNA.

Now, the same virus has served as a template for functional genomes generated with the help of AI.

The newly created viruses were also highly selective. They infected two closely related laboratory strains of E. coli but failed to reproduce in six other bacterial strains tested. Because they are bacteriophages, these viruses do not infect human cells.

Researchers also combined several of the AI designed viruses and tested them against three E. coli strains that had developed resistance to the natural ΦX174 virus. The AI generated combinations successfully overcame all three resistant strains, while the original virus did not.

Although this technology could eventually contribute to new approaches for treating antibiotic resistant bacterial infections, it also raises major biosecurity concerns.

Scientists warn that as biological AI systems become more powerful, similar technologies could potentially be misused to design viruses or other biological agents capable of affecting humans, animals, or crops.

Is your neck hump caused by too much screen time?

Looking down at your phone or laptop for hours forces your head forward, putting extra pressure on your neck and upper back. Over time, this can weaken the muscles, tighten the shoulders, and contribute to poor posture and a neck hump.

Research has linked prolonged screen use and forward head posture to neck pain and spinal strain.

Try keeping your screen at eye level, sitting up straight, and taking breaks every hour.

Small posture changes can make a big difference for your spine.

A dangerous fungal disease spread by cats could eventually reach the United States, according to U.S. health officials.

The Centers for Disease Control and Prevention (CDC) is monitoring the spread of Sporothrix brasiliensis, a contagious fungus that can pass from cats to humans through scratches, bites, and, in some cases, respiratory secretions. Unlike most fungal infections, which are usually acquired from the environment, this strain spreads efficiently between animals and people.

Infected cats often develop painful skin ulcers and swollen lymph nodes. Without treatment, the infection can spread throughout the body and become fatal. In humans, the fungus typically causes severe skin lesions, although rare cases can become life threatening, especially in people with weakened immune systems.

Although Sporothrix brasiliensis has not yet been officially identified in the United States, experts warn that its arrival may be inevitable. The fungus has already caused a large outbreak in South America, infecting thousands of cats and humans since it first emerged in Brazil, and has recently been detected in the United Kingdom.

Because there is currently no rapid screening test for imported pets, veterinarians and pet owners are encouraged to watch for unusual skin lesions in cats that have traveled internationally and seek specialized testing when necessary.

More parents in the United States are refusing the vitamin K shot given to newborns shortly after birth, and doctors warn that the decision is leading to preventable cases of severe internal bleeding.

Babies are born with very low levels of vitamin K, a nutrient that helps the blood clot properly. Because only small amounts pass through the placenta and breast milk, newborns remain vulnerable during their first weeks of life.

Without the injection, bleeding can occur suddenly and without warning. Symptoms may include seizures, vomiting, breathing difficulties, or bleeding from the nose and umbilical cord. In severe cases, bleeding around the brain can cause permanent disability or death.

According to the CDC, about 20% of babies who develop vitamin K deficiency bleeding do not survive.

The vitamin K shot has been recommended for newborns in the United States since 1961. Research shows that the risk of late vitamin K deficiency bleeding drops from roughly 1 in 14,000 to 1 in 25,000 births to less than 1 in 100,000 after receiving the injection.

Recent data suggest that refusal rates are rising. A study of more than 5 million births found that over 5% of babies did not receive the shot in 2024, a significant increase compared with 2017.

Health experts emphasize that vitamin K is not a vaccine, does not contain mercury, and has not been linked to cancer. Doctors fear that because the shot has been so successful for decades, many parents no longer realize how important it is for protecting newborns.

New research published in PLOS One suggests that excessive internet use may increase stress, worsen mood, and reduce overall well being. In a study of 900 adults, researchers found that problematic internet use was associated with higher stress levels, more negative emotions, and difficulties keeping up with everyday responsibilities. Experts say spending too much time online can also lead to less physical activity, greater fatigue, and weaker face to face relationships.

Limiting sugar intake during pregnancy and early childhood may reduce the risk of dementia later in life, according to a new study published in Neurology.

Researchers used the end of sugar rationing in the United Kingdom in 1953 as a natural experiment. After rationing ended, average sugar consumption nearly doubled. By analyzing data from almost 65,000 participants in the UK Biobank, scientists compared people exposed to lower sugar levels during fetal development and the first two years of life with those born after restrictions were lifted.

The study found that individuals with lower early life sugar exposure developed dementia about 2.6 years later on average and showed better preservation of brain structure and gray matter volume.

Although the findings do not prove that reducing sugar alone prevents dementia, they highlight the importance of nutrition during the first 1,000 days of life, a critical period for brain development. Researchers suggest that limiting added sugars early in life could help support long term brain health and lower the risk of cognitive decline.

Sparkling water can temporarily make your mouth more acidic, but the effect is much smaller than sugary soda.

Researchers at Purdue University studied 20 adults who drank four types of beverages: regular sugary soda, plain sparkling water, calcium enriched sparkling water, and still water.

The study found that soda caused the biggest and longest lasting decrease in saliva pH. Sparkling water also lowered mouth pH for a short time, but saliva returned the mouth to near normal acidity within around 20 minutes.

The acidity level after drinking sparkling water stayed above pH 5.5, the point where tooth enamel may begin to weaken.

The results suggest that choosing unsweetened sparkling water instead of sugary soda could be a better option for protecting teeth. However, sparkling water is not completely risk free. Drinking it frequently throughout the day may expose teeth to acid more often, and flavored versions may contain extra acids or sugars that increase potential risks.

Tooth erosion usually happens after repeated acid exposure over a long period, not from drinking one beverage.

The study only looked at short term saliva changes and did not measure actual enamel damage, cavities, or long term dental effects. It was also a small study that has not yet gone through peer review, so the findings are still considered preliminary.

For people deciding between plain sparkling water and sugary soda, current evidence suggests sparkling water is the less harmful choice for dental health.

A dangerous drug resistant superbug called Acinetobacter baumannii may be able to spread between pets and humans, according to new research.

Scientists found that bacterial samples from cats, dogs, and horses were genetically almost identical to strains found in hospitalized patients, suggesting that close contact between animals and people could allow transmission.

However, researchers say more studies are needed to determine how often this type of spread actually occurs.
