Long COVID: SARS-CoV-2 spike protein accumulation linked to long-lasting brain effects

Researchers at Helmholtz Munich identified a mechanism explaining Long COVID's neurological symptoms: SARS-CoV-2 spike protein remains in the brain for up to four years after infection. mRNA COVID-19 vaccines significantly reduce spike protein accumulation, but persistent presence poses a toxic risk.

Room-temperature ferroelectricity and data storage potential in tellurium nanowires

Researchers have discovered room-temperature ferroelectricity in single-element tellurium nanowires, paving the way for advancements in ultrahigh-density data storage. The discovery also enables fast switching speeds of less than 20 nanoseconds and impressive storage density exceeding 1.9 terabytes per square centimeter.

Interim dollar gains, cybersecurity pains

Research by SMU's School of Accountancy found that data breaches rose nearly eight times between 2005 and 2018, with average costs reaching US$388 million. To mitigate this issue, managers should realign incentives and foster a corporate culture valuing long-term sustainability over short-term gains.
