This challenges the notion of a meritocracy, where success is solely based on individual effort. The research highlights the significant advantage these students have due to their family's socioeconomic status.
Research by Professor Mila Vulchanova reveals associations between language development and cognitive skills in children. Non-verbal tests show that severity of language difficulties can be predicted based on cognitive markers, supporting the importance of measuring both verbal and non-verbal skills.

Patients with and without SUD had similar clinical complications, including mechanical ventilation and ICU admission.
A cohort study found that nirmatrelvir treatment within five days of a positive COVID-19 test result was associated with reduced post-COVID-19 condition risk, regardless of vaccination status and prior infection history. The study suggests that nirmatrelvir may reduce the risk of long COVID across the risk spectrum.
A new report reveals that children born into the poorest fifth of families in the UK are 12 times more likely to experience poor health and educational outcomes by age 17. This clustering of adverse outcomes is linked to early childhood disadvantage, with modest reductions seen when lifting families out of poverty.
Researchers found that physical activity can prevent cancer recurrence in stage III colon cancer patients by lowering the recurrence rate within the first year of treatment. This association persisted for approximately three years after surgery, suggesting a long-term survival benefit.

A recent large-scale Netherlands cohort study found that growing up in an affluent neighborhood has a more significant positive impact on educational attainment than growing up in a poor one. Exposure to affluence was found to have a greater effect, surpassing the negative effects of poverty.
After six months of disrupted schooling during the COVID-19 pandemic, German students scored substantially lower on intelligence tests compared to earlier cohorts. The gap in test scores persisted even after sixteen months of irregular schooling.
A new study published in The Lancet found that contracting a respiratory infection in early childhood is associated with a higher risk of dying from respiratory disease as an adult. Children who had a lower respiratory tract infection (LRTI) before the age of two were 93% more likely to die prematurely from respiratory disease, account...
A US FDA mandate to limit acetaminophen dosage in pills combining it with opioids significantly reduced hospitalizations and acute liver failure cases. Researchers found a persistent decline in yearly rates of these cases after the mandate was implemented in 2014.
A one-year case-control study found increased rates of adverse outcomes among adults with long COVID compared to those without COVID-19, highlighting the need for continued monitoring, particularly in cardiovascular and pulmonary management. The study's findings underscore the importance of addressing at-risk individuals.
A review of dozens of studies found a positive association between sugary drinks and weight gain in both adults and children, with increasing SSB intake linked to greater weight gain over time. Limiting SSB consumption is an effective way to prevent age-related weight gain.
A growing gap in NIH funding created an elite class of super principal investigators with persistent gaps in gender, ethnicity, and race. Researchers highlighted the critical need for reform to promote equity among NIH investigators.
A recent study found that bacterial co-infection in COVID-19 patients significantly increased the risk of death, intensive care unit admission, and mechanical ventilation. The study reviewed 13,781 COVID-19 inpatient encounters and identified laboratory trends associated with COVID-19 bacterial co-infection.
Researchers re-examine molecular characteristics of WNT-subgroup patients to identify optimal treatment strategies for low-risk medulloblastoma.

The research analyzed data from over 4,300 American mothers and their children, revealing that children of mothers with adverse experi...
Researchers have identified three novel pathogenic variants of the ATR gene as predisposing to male breast cancer. These variants were found in a cohort of individuals with early onset and familial breast cancers, using a combination of exome sequencing and functional investigations. The study suggests that extended genetic analysis ca...
Researchers found that a combination of symptom and high-level viral rebound after untreated COVID-19 infection is rare, occurring in only 3 percent of study participants. This suggests that accounting for underlying rates of symptom relapse is crucial when evaluating antiviral treatment effects.
Researchers found SARS-CoV-2 in 18.2% of tear samples from patients with COVID-19, and in 12.1% of those collected using the Schirmer strip test. The method may predict patient prognosis and provide an alternative to uncomfortable nasopharyngeal swabbing.
