Frequently distracted? Your brain rhythms may be to blame Attention naturally shifts rhythmically about 7–10 times per second, creating alternating periods of heightened and reduced focus. These cycles, once advantageous for environmental monitoring, now increase susceptibility to distractions from digital stimuli. EEG data show that during low-focus phases, individuals are more easily distracted, suggesting implications for understanding conditions like ADHD.

Study finds more parents saying 'no' to vitamin K at birth, putting babies' brains at risk
Increasing numbers of parents are refusing vitamin K shots for their newborns, putting infants at greater risk of avoidable brain injuries, according to a preliminary systematic review released February 26, 2026.
A vitamin K injection is a supplement that provides babies with an essential vitamin that is naturally low in newborns. It is not a vaccine. Vitamin K is needed to help blood clot. Getting a vitamin K shot right after birth can prevent a rare but serious condition called vitamin K deficiency bleeding. This condition can cause an intracerebral hemorrhage, a type of stroke, when a blood vessel bursts in the brain, which can lead to death or lifelong brain problems. Refusal of vitamin K injections at birth is increasing in several regions, raising the risk of vitamin K deficiency bleeding in newborns, which can cause brain hemorrhage, death, or long-term neurological disability. Infants without the injection are 81 times more likely to develop this condition. Refusal is also linked to declining other newborn health interventions.
Researchers found that among case series reports of babies who had vitamin K deficiency bleeding, approximately 14% of the babies died, about 40% had long-term neurological disabilities such as cognitive impairment, seizures or motor deficits, and about 63% of babies had brain bleeds.
They also found that parents who refused vitamin K for their babies were more likely to skip other recommended health protections.
Parental concerns included pain, preservatives and belief in inaccurate information.

Tick bites can introduce the alpha-gal sugar molecule into the bloodstream, leading some individuals to develop IgE antibodies and become sensitized to mammalian meat allergy. Subsequent consumption of red meat or products containing alpha-gal can trigger allergic reactions, including potentially fatal anaphylaxis. Most cases occur in older adults, with incidence rising mainly due to increased awareness and testing. There is no cure for mammalian meat allergy. So preventing tick bites is best:
wear long-sleeved shirts and long pants when walking or working in areas where there are ticks tuck pants into long socks wear a wide-brimmed hat wear light-colored clothing use insect repellent, particularly ones containing DEET.

A tick bite can cause a deadly meat allergy
Tick bites can introduce the alpha-gal sugar molecule into the bloodstream, leading some individuals to develop IgE antibodies and become sensitized to mammalian meat allergy.
