Excited to share our latest #epigenetics and #memory in @npp_journal. We show that splice isoforms of histone macroH2A1 have distinct effects on memory and hippocampal gene regulation, especially memory suppressors. https://t.co/udzppqQF9N

The brain is built in two halves. So why does consciousness feel like one seamless experience?
In an excerpt from "Consciousness," neuroscientist Christof Koch explores what split-brain patients reveal about the unity of the mind: https://t.co/5HDYKad6Ub
“We are at a unique stage in our history. Never before have we had such an awareness of what we are doing to the planet, and never before have we had the power to do something about that... The future of humanity and indeed all life on earth, now depends on us.”
— Sir David Attenborough
Whether or not Europe stands with us, whether or not your journalists do their jobs, whether or not your politicians demonstrate the courage to act, I will fight for my people and my country.
The best view in the universe is the one we call home. 🌎
Earth is the only home we have ever known, and from space its beauty is undeniable. This Earth Day, we honor the astronauts who see it from above, the scientists who study it from below, and the teams at Johnson Space Center who make that work possible. Seeing our world from space reminds us why protecting it matters for generations to come.

The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.
🗓️ Exactly five weeks ago on Saturday 28 February, #Iran cut off access to the global internet.
The measure remains in place, entering day 36 after 840 hours, isolating the general public as authorities explore ways to give chosen users access via a tiered whitelisting system.
Liftoff.
The Artemis II mission launched from @NASAKennedy at 6:35pm ET (2235 UTC), propelling four astronauts on a journey around the Moon.
Artemis II will pave the way for future Moon landings, as well as the next giant leap — astronauts on Mars.
⚠️ Update: #Iran's internet blackout has entered day 32 with most users cut off from the outside world for over 744 hours.
Extended digital isolation is bringing new challenges for Iranians, from expired domains and accounts to unpatched servers on a degrading national intranet.
The Crown Prince received a massively favorable welcome at CPAC, where there was a large number of Persian Americans. Worth keeping that in mind. I believe he’s very popular among the people in Iran.

My story on Iran’s attempt to use a famed director to push its war narrative, and his son’s response: “Keep him out of your rhetoric.” https://t.co/KRoSKU2a7g
⚠️ Update: #Iran's digital blackout has entered its 27th day after 624 hours of isolation from the global internet with connectivity levels at ~1%.
Rights monitors, independent media and the public are sidelined as access is granted only to those on a state-approved whitelist.
Nowruz is one of the most important Persian holidays and coincides with the vernal equinox and the first day of spring.
In the days leading up to Nowruz, Chahārshanbe Sūrī (Fire Wednesday) is celebrated by jumping over bonfires, a ritual that marks the transition into the new year, casting off the past year’s hardships and welcoming light and health. Fire symbolizes purification and cleansing in Persian tradition, and is often vividly depicted in miniature painting, as in this scene.
📕 ‘The Fire Ordeal of Siyāvush,’ Folio 104v from the Shāhnāmah (‘Book of Kings’) of Firdawsī, attributed to Shiraz, Iran, copied for “Muḥammad Sharīf” by Muḥammad ‘Alī, in 1023/1614.
Today, we mark Nowruz, the start of a new year for Persian communities in Ontario and around the world.
This year, many Iranians enter the new year with heavy hearts, while remaining optimistic for a free and democratic Iran. Nowruz remains a symbol of resilience, strength and hope for better days ahead. Nowruz Pirooz.
