Dear @TNTSportsUS - big miss not solely focusing on Stan Wawrinka in this final match of his to do split screen with a first round other match - then not showing it at all. Completely disrespectful of this FO champion in his last Roland Garros match. Do better. #RolandGarros

Alcaraz taking a page from the Nadal and Djokovic gamesmanship playbook. Barely walking one minute. Running down everything and playing full tilt the next. Injuries have a miraculous way of disappearing. #AustralianOpen2026

The work of finding solutions to ending the #HIV epidemic does not begin or end with government endorsement. It sits with community. Always has. Always will. Continue to do the good work we all have been doing for 40 years. It matters now more than ever. #WorldAIDSDay2025

Dear @GetUpESPN - your bias is showing. Stop whining about "officiating" now that the KC Chiefs are 0-2. They lost to the Eagles. Get over it. Amazing how you never complain about officiating when it helps KC win games (and Superbowls). At least try to be objective. #ESPN #NFL

Gonna be great when we actually see Djokovic against some real competition. How does he always get these cake walk draws and always seem to get Cam Norrie each GS? Then when he runs up against ranked players and gets beat, the media says "what happened?" #USOpen

To witness an icon of public health step away from the work he loves is discouraging. Due to politics, misinformation, and the elevation of ignorant conspiracy theories over real science. Thanks for your service @dr_demetre - your work will continue!

My resignation letter from CDC. Dear Dr. Houry, I am writing to formally resign from my position as Director of the National Center for Immunization and Respiratory Diseases at the Centers for Disease Control and Prevention (CDC), effective August 28, 2025, close of business.   I am happy to stay on for two weeks to provide transition, if requested. This decision has not come easily, as I deeply value the work that the CDC does in safeguarding public health and am proud of my contributions to that critical mission. However, after much contemplation and reflection on recent developments and perspectives brought to light by Secretary Robert F. Kennedy Jr., I find that the views he and his staff have shared challenge my ability to continue in my current role at the agency and in the service of the health of the American people. Enough is enough. While I hold immense respect for the institution and my colleagues, I believe that it is imperative to align my professional responsibilities to my system of ethics and my understanding of the science of infectious disease, immunology, and my promise to serve the American people.  This step is necessary to ensure that I can contribute effectively in a capacity that allows me to remain true to my principles. I am unable to serve in an environment that treats CDC as a tool to generate policies and materials that do not reflect scientific reality and are designed to hurt rather than to improve the public’s health.  The recent change in the adult and children’s immunization schedule threaten the lives of the youngest Americans and pregnant people.   The data analyses that supported this decision have never been shared with CDC despite my respectful requests to HHS and other leadership.  This lack of meaningful engagement was further compounded by a “frequently asked questions” document written to support the Secretary’s directive that was circulated by HHS without input from CDC subject matter experts and that cited studies that did not support the conclusions that were attributed to these authors.  Having worked in local and national public health for years, I have never experienced such radical non-transparency, nor have I seen such unskilled manipulation of data to achieve a political end rather than the good of the American people. It is untenable to serve in an organization that is not afforded the opportunity to discuss decisions of scientific and public health importance released under the moniker of CDC.  The lack of communication by HHS and other CDC political leadership that culminates in social media posts announcing major policy changes without prior notice demonstrate a disregard of normal communication channels and common sense.  Having to retrofit analyses and policy actions to match inadequately thought-out announcements in poorly scripted videos or page long X posts should not be how organizations responsible for the health of people should function.  Some examples include the announcement of the change in the COVID-19 recommendations for children and pregnant people, the firing of scientists from ACIP by X post and an op-ed rather than direct communication with these valuable experts, the announcement of new ACIP members by X before onboarding and vetting have completed, and the release of term of reference for an ACIP workgroup that ignored all feedback from career staff at CDC. The recent term of reference for the COVID vaccine work group created by this ACIP puts people of dubious intent and more dubious scientific rigor in charge of recommending vaccine policy to a director hamstrung and sidelined by an authoritarian leader.   Their desire to please a political base will result in death and disability of vulnerable children and adults.  Their base should be the people they serve not a political voting bloc. I have always been first to challenge scientific and public health dogma in my career and was excited by the opportunity to do so again.  I was optimistic that there would be an opportunity to brief the Secretary about key topics such as measles, avian influenza, and the highly coordinated approach to the respiratory virus season.  Such briefings would allow exchange of ideas and a shared path to support the vision of “Making America Healthy Again.”  We are seven months into the new administration, and no CDC subject matter expert from my Center has ever briefed the Secretary.  I am not sure who the Secretary is listening to, but it is quite certainly not to us.  Unvetted and conflicted outside organizations seem to be the sources HHS use over the gold standard science of CDC and other reputable sources.  At a hearing, Secretary Kennedy said that Americans should not take medical advice from him.  To the contrary, an appropriately briefed and inquisitive Secretary should be a source of health information for the people he serves. As it stands now, I must agree with him, that he should not be considered a source of accurate information. The intentional eroding of trust in low-risk vaccines favoring natural infection and unproven remedies will bring us to a pre-vaccine era where only the strong will survive and many if not all will suffer.  I believe in nutrition and exercise.  I believe in making our food supply healthier, and I also believe in using vaccines to prevent death and disability.  Eugenics plays prominently in the rhetoric being generated and is derivative of a legacy that good medicine and science should continue to shun. The recent shooting at CDC is not why I am resigning.  My grandfather, who I am named after, stood up to fascist forces in Greece and lost his life doing so.  I am resigning to make him and his legacy proud.   I am resigning because of the cowardice of a leader that cannot admit that HIS and his minions’ words over decades created an environment where violence like this can occur.  I reject his and his colleagues’ thoughts and prayers, and advise they direct those to people that they have not actively harmed. For decades, I have been a trusted voice for the LGBTQ community when it comes to critical health topics.  I must also cite the recklessness of the administration in their efforts to erase transgender populations, cease critical domestic and international HIV programming, and terminate key research to support equity as part of my decision. Public health is not merely about the health of the individual, but it is about the health of the community, the nation, the world. The nation’s health security is at risk and is in the hands of people focusing on ideological self-interest. I want to express my heartfelt gratitude for the opportunities for growth, learning, and collaboration that I have been afforded during my time at the CDC. It has been a privilege to work alongside such dedicated professionals who are committed to improving the health and well-being of communities across the nation even when under attack from within both physically and psychologically. Thank you once again for the support and guidance I have received from you and previous CDC leadership throughout my tenure. I wish the CDC continued success in its vital mission and that HHS reverse its dangerous course to dismantle public health as a practice and as an institution.  If they continue the current path, they risk our personal well-being and the security of the United States. Sincerely, Demetre C. Daskalakis MD MPH (he/his/him)

It is funny that MAGA cultist want to challenge my blackness because of my education… Remember how they challenged Barack Obama & his roots? Remember how they claimed Kamala “turned”black. Y’all are a joke. Walk a day in my shoes where your white supremacist friends send me hateful emails, death threats, DMs, & posts, and then you can tell me if I’m truly living the black experience in this country, UNTIL then mind your business. *ALSO “being black” has nothing to do with education… (BUT for the record, if it did, just know that the MOST educated demographic in THIS country is BLACK WOMEN 🎤 so stop pretending like we are inferior in ANY WAY!)

I'm devastated. Truly gifted brother who expanded a life's career on his break with the Cosby Show. Sending love to his family and other loved ones. Grew up with Malcolm-Jamal Warner, the character of Theo, and the interactions with his TV dad that resembled mine. RIP.
21 Jul 2025
We’re heartbroken to report the passing of Malcolm-Jamal Warner at the age of 54 from an apparent drowning. A generation grew up with Warner as Theodore “Theo” Huxtable. His portrayal helped redefine Black boyhood on screen, offering humor, vulnerability, and depth across eight seasons. May he rest in peace.

This man... soundtrack of so many of our lives.
The world lost the great Luther Vandross on this day 20 years ago. Luther was one of the greatest voices in music history. To the superstar whose first name alone brings instant recognition and admiration, Luther, we love and miss you.
