[Sana Ebrahimi Ledene @SanaELedene]

Thousands of Iranian students came to the U.S. legally.

They went through one of the longest and strictest vetting processes of any nationality. They studied here, followed the law, and are now PhD graduates, doctors, engineers, and researchers contributing to American science and innovation.

But now their immigration cases are suddenly stopped.

• OPT for Iranian graduates has been paused, meaning many who just finished their degrees cannot work in the fields they trained for.
• Some were waiting for Employment Authorization Documents, paused.
• Some were waiting for green cards, stalled.
• Others were in the middle of an Adjustment of Status, now frozen.

This pause was supposed to last 90 days to review vetting procedures.

Many are now in limbo.

These are people who followed every rule, built careers here, and are among the highest-tax-paying communities in the U.S.

Punishing the very people who came legally and contribute to American science, medicine, and technology makes no sense.

Very sad to hear that UMass is rescinding all PhD admissions for Fall 2025. This means there will be no new PhD cohort, and UMass will not have a graduating class that year. This is just unprecedented and I am so very sorry for all the affected students.

NEW: Today, I’m releasing a Surgeon General’s Advisory on the causal link between alcohol consumption and increased cancer risk. Alcohol is the 3rd leading preventable cause of cancer in the U.S., contributing to about 100,000 cancer cases and 20,000 cancer deaths each year.

Understanding the difference between Standard Deviation (SD) and Standard Error (SE) is crucial for accurate data interpretation. SD measures the variability within your data, indicating how spread out the individual data points are from the mean.

In contrast, SE measures the uncertainty around the sample mean as an estimate of the population mean. It reflects the precision of the mean, with SE decreasing as the sample size increases, making your estimate more reliable.

The relationship between SD and SE is given by the formula: SE = SD / √(sample size). While SD remains relatively constant with larger samples, SE diminishes, highlighting the reduced uncertainty in the mean estimate.

A common mistake in research is using the “±” notation without specifying whether it refers to SD or SE, leading to potential misinterpretation of the data. Clear distinction is essential for transparency and accuracy in reporting.

Key Takeaways:
• Use SD to describe data variability.
• Use SE to indicate the precision of the mean.
• Always specify which measure you are reporting.

This study using 5 waves of PATH found that many older adults who smoke perceive e-cig as equally or more harmful than cigarettes, particularly low-SES and Black older adults. This could negatively influence cessation attempts and switching behaviors. https://t.co/lDeIe2WvA7

In 2024, 5.9% of U.S. middle and high school students used e-cigarettes, with a significant decline from 2023, which was 7.7%. However, nicotine pouch use remained unchanged, affecting approximately 480,000 students. https://t.co/MUR25G5IlR

Graph I created from NSDUH 2022 and 2023 data: In 2023, 13.7% (38.7M) aged 12+ smoked vs 9.4% (26.6M) vaped last month. E-cigs still dominate 18-25 (24.1%), and cigs lead 26+ (15.5%). Youth prefer vaping but use it less compared to 2022 (6.8% vs 6.9%). https://t.co/5zSOy9ibRF

In 2022, 67.7% of the 28.8M U.S. adults who smoked cigarettes wanted to quit, 53.3% attempted, but only 8.8% succeeded. Among menthol smokers, quit interest and attempts were higher, but advice and treatment were lower compared to non-menthol smokers.
