1000 days ago, during the October 7 massacre, Hamas executed an 18-year-old girl in front of her entire family. Then they dragged her father away, kidnapped him, and murdered him in captivity. They filmed every second live... and proudly posted it for the world to see ๐Ÿ’”

๐Ÿ”ด This story says everything. Eyal Waldman, one of Israelโ€™s top high-tech innovators & founder of Mellanox, believed in peace through opportunity. In 2017, he opened a development hub inside Gaza, giving hundreds of Palestinian engineers high-paying jobs, dignity, and a future. He said proudly: โ€œThere are talented and smart people in Gaza. Cooperation reduces fear. Working together brings our nations closer.โ€ ๐Ÿ‘‰ He chose hope. ๐Ÿ‘‰ He chose coexistence. ๐Ÿ‘‰ He chose to invest in the very people the world said Israel was โ€œoppressing.โ€ And then came October 7. Palestinian terrorists crossed the border and murdered his 24-year-old daughter, Danielle, less than a mile from the center he built to give Gazans opportunity. Read that again: He - gave - them - jobs. This is the truth people refuse to look at: Israel reached out with opportunity. Hamas answered with slaughter. If this doesnโ€™t expose the lie behind the โ€œresistanceโ€ narrative, nothing will.

On October 7th, the Idan family of the Nahal Oz Kibbutz lost their daughter Maayan, 18. Then, Hamas kidnapped her father Tsachi to Gaza and killed him too. ๐Ÿ•ฏ๏ธTsachi Idan, 49 This is the last image of Tsachi, seen in the foreground holding his son, wife and daughter. Moments before, his 18-year-old daughter, Maayan was shot by terrorists and died in his arms. Someone took his wife Galiโ€™s phone and livestreamed the horrors from her Facebook page to all her friends, warning neighbors what would soon await them. In the footage, the family was huddled on the kitchen floor. They are covered in Maayan's blood. Meanwhile, Tschai's younger kids are heard asking "are they killing us? are they killing us" in Hebrew. Tschai's hands were then cuffed behind his back, in one of the most well-documented abductions in his kibbutz. The children were overheard begging the Palestinians not to take their dad, not to kill him. "I love you, don't be a hero, be smart. Take care of yourself, and come back to me in one piece.โ€ Gali screamed as the drag Tsachi away. Tsachi was later murdered in captivity. Pure evil is bred and cultivated in Gaza by design, and we must figure out what needs to be done so we can live in peace ๐ŸŽ—๏ธ

Journals canโ€™t find peer reviewers. Preprints arenโ€™t taken seriously. Garbage papers slip through peer review. Meantime, AI is slowly taking over. Nature describes the current situation. I highly recommend reading the article. ๐Ÿ“ The summary (+ my comments): 1. We are facing a SIGNIFICANT overload on reviewers. Fatigue is epidemic. Few scientists have time for much peer review. As a result, manuscript turnaround times are chaos. Theyโ€™re unpredictable and painfully slow. 2. Grant and facility proposals demand massive peer review too. They push the system even further. 3. Review quality is decreasing. Rigor is inconsistent. Technical aspects are poorly assessed. 4. Gatekeeping and bias are very real (we all know how manuscripts are rejected due to competition & jealousy). It causes a growing dissatisfaction among scientists. 5. Paid reviewing does NOT automatically improve the acceptance rate. Trials show mixed results. For example, acceptance rates barely increased from 48% to 53% for Critical Care Medicine. The quality of PR remained the same. But for Biology Open, the PR process has become much faster. In either case, paid reviews are very hard to scale business-wise. 6. Distributed Peer Review is becoming more popular. Some funding agencies now require applicants to review peersโ€™ proposals. But to to eliminate bias in it? I donโ€™t know. โ— Thereโ€™re no simple solutions. As a careful observer, I think that the complex picture is evolving along the following trajectory: AI-assisted peer view (AI pre-screening, AI PR-assistant, AI audition of peer reviews) + Community reviewing + Some form of compensation + Involvement of wider community in PR lists (not only most recognized scientists) Whatโ€™s your view on it?

Unfortunately itโ€™s clear that the Israeli people (although we are the majority since Oct 7th) canโ€™t topple the government or change its ways. Seems like the attorney general, the last gate keeper, will be fired soon. As long as weโ€™re stuck with this government, the war wonโ€™t stop. Only international intervention (=the U.S) might do it. Three years of massive demonstrations (in some of them >10% of the population were on the streets) didnโ€™t change a thing. This is a shameless and corrupted government that will stop at nothing. Bibi (and Hamas) will continue the war for one reason - to stay in power. They donโ€™t care if all the Israeli hostages and innocent people in Gaza die. What type of international intervention do we need? Iโ€™m not sure, but if you think boycotts that target the governmentโ€™s opposition (academia, art, culture -> all are part of the left) are helpful, then Iโ€™m not following the logic. These are the same groups Bibi is trying to suppress. Instead, international intervention should strengthen the liberals and suggest alternatives (and force a deal, back it up).

My lab at @WeizmannScience was completely demolished by the Iranian missile a few days ago. This is hard and sad as nothing was left to save. We study heart regeneration and regenerative medicine. As such, we will regenerate, regrow and rebuild. The one thing that wasn't gone is our motivation said one of my student. It is true. Here, I would like to thank many of my friends around the globe that offer their help, space and support. I really appreciate that.
