Hamas has tried to obstruct any progress towards peace for decades. That is their mission. They are not representative of all Palestinians. They have held the region, including both Jews and Arabs, hostage.

These are 38 Israeli children uprooted from their lives, abducted and held by Hamas for more than a month. There are 240 hostages all in all. No one knows what condition they are in. Enough. #bringthemhome #ReleaseTheHostagesNow

Yemen, my poor country, has decided to bomb Israel. My poor country is more concerned with killing Jews than feeding its starving population. This is the problem with the Arab world. Blind unforgiving hatred. Wrong choices. And psychopathic leadership. More than 75% of the

This is Aviv. A beautiful little Israeli girl, who is just 2 years old. On Oct 7th, she was kidnapped from her home in southern Israel by Hamas terrorists and abducted to Gaza. I cannot even fathom how terrified she must be. Bring Aviv back! #BringThemHomeNow

The situation is so absurdly simple: Hamas declared war in the most horrifying, gruesome, and extreme way possible. On a scale of FIFTEEN 9/11s, but also beheaded babies and raped children and the elderly until their bones broke and they died. Every day Hamas refuses to hand over

My first first-author paper with @chayakalcheim is out @eLife! ๐Ÿฅณ We found a mechanism responsible for the end of neural crest production, leading to the separation between peripheral and central nervous system branches. https://t.co/m2PgrvaO4j 1/8

BMP-dependent retinoic acid signaling is responsible for the separation of central from peripheral lineages during neural development.
