The Lancet Respiratory Medicine: Two years after infection, half of people hospitalized with COVID-19 have at least one symptom, follow-up study suggests

A follow-up study published in The Lancet Respiratory Medicine found that half of people hospitalized with COVID-19 have at least one symptom two years after infection. Long COVID symptoms persist, affecting quality of life, mental health, and healthcare use.

Taking ownership of your health

A study published in Age and Ageing found that modifying lifestyle behaviors can have a marked effect on lifespan, particularly among older adults and those with chronic conditions. Adopting five or more healthy habits increased life expectancy by up to 6 years for healthy 40-year-olds.

Novel supramolecular CRISPR–Cas9 carrier enables more efficient genome editing

A team of researchers from Kumamoto University has developed a transformable polyrotaxane carrier that can facilitate genome editing using Cas9RNP with high efficiency. The carrier, called amino-PRX, is multi-step transformable and has low cytotoxicity, making it an enormously promising candidate for safe and efficient delivery.

Neoliberal policies, institutions have prompted preference for greater inequality, new study finds

A new study by NYU researchers found that neoliberal policies and institutions are associated with a preference for greater income inequality across over 160 countries. The analysis, which spanned 25 years (1995-2019), suggests that economic systems can shape human psychology to favor higher levels of income inequality.

Genetic study identifies migraine causes and promising therapeutic targets

Researchers have found blood proteins that cause migraine, including DKK1 and PDGFB, which inhibit Wnt signalling pathways. Lower levels of antioxidant proteins FARS2, GSTA4, and CHIC2 also contribute to inflammation linked to migraine. Therapies targeting increased DKK1 levels may represent novel tools for treatment.

Hope for Europe’s 23 million acne sufferers as dermatologists identify possible link between key nutrient and skin condition / Akne Patienten zeigen erniedrigte Omega-3 Fettsäure Spiegel

Dermatologists identify a possible link between acne and omega-3 fatty acids, finding that 94% of patients had below-recommended levels in their blood. A healthy diet rich in legumes and avoiding sunflower oil may help manage the condition. The study suggests that omega-3 supplements could be beneficial for treating acne.

Exploring the ocean's thin skin

Researchers study the sea-surface microlayer, a biogeochemical reactor where organisms adapt to harsh conditions like UV radiation and fluctuating temperatures. The team aims to understand biological, chemical, and physical interactions in this thin layer, influencing global climate.

Low-energy protons from strong-field breaking of hydrogen

A joint research team investigated the generation of low-energy protons in dissociative ionization of H2 using time-energy-resolved spectroscopy. They found that low-energy protons are produced via dipole-transition at large bond lengths, contrary to the expected bond-softening scenario.

Springing people from the poverty trap

A field experiment in Bangladesh shows that the poor lack opportunities to gain wealth, but a one-time boost can make a major difference. The study suggests that poverty is not principally due to people's capabilities or attitudes, but rather an initial lack of resources prevents them from improving their circumstances.

Stress may be associated with fertility issues in women

A recent study published in Endocrinology found that exposure to a scream sound may lead to diminished ovarian reserve and decreased fertility in female rats. The researchers discovered that the scream sound reduced estrogen and Anti-Mullerian hormone levels, as well as the number and quality of eggs, resulting in smaller litters.
