A new Science paper challenges the idea that language stems from a single evolutionary root. Instead, it proposes that our ability to communicate evolved through the interaction of biology and culture, and involves multiple capacities, each with different evolutionary histories. The framework unites discoveries across disciplines to explain how the ability to learn to speak, develop grammar, and share meaning converged to create complex communication.

Shanghai Ranking by Research Fields for 2025: The Hebrew University ranks among the world’s top 50 in four fields, including Public Administration, which jumped dozens of places to reach 23rd worldwide - higher than Harvard.

The Hebrew University of Jerusalem is proud to announce the establishment of a new International Research Center on Democracy, Security and Human Rights, in collaboration with the Max Planck Society, Germany’s leading organization for basic research.

The Hebrew University of Jerusalem held a special ceremony this week honoring the recipients of the Waldman Family Scholarship and the long-standing Yashinsky Prize.

Prof. Tamir Sheafer, President of the Hebrew University, joined Mr. Eyal Waldman, Israel Prize laureate and founder of Mellanox, and his brother Mr. Ofer Waldman, in presenting the awards to exceptional researchers from across the university.

In recent months, we have observed with concern an increase in calls for boycotting Israeli institutions, including our own. It is important to note the following:

• Israeli academia operates independently of the Israeli government and plays a crucial role in promoting critical thinking within Israeli society. Israeli academia is the backbone of Israeli civil society.

State-funded five-star hotel stays may sound appealing for a weekend, but when thousands of Israelis were evacuated to hotels during the October 7th war, the experience quickly proved far from idyllic. A new study reveals how hotels- symbols of a “luxury experience”, can mirror the psychological pains of imprisonment during wartime, raising urgent questions about the complex experiences of displaced communities, even under seemingly ideal conditions.

A new experiment called QROCODILE, led by the University of Zurich and the Hebrew University of Jerusalem, has achieved record sensitivity in the hunt for light dark matter. Using superconducting detectors cooled to near absolute zero, the team set world-leading limits on how dark matter interacts with ordinary matter — opening the door to future breakthroughs in one of physics’ greatest mysteries.

A new study shows that a TXA autoinjector delivers lifesaving treatment for severe bleeding as effectively as traditional IV methods — but in under five minutes and without the need for medical expertise. This breakthrough could transform trauma care in emergencies, making rapid, easy-to-administer treatment available in settings ranging from battlefields to roadside accidents, where every second counts.

Bacteria aren’t just mindless microbes. New research from the Hebrew University of Jerusalem reveals that single bacterial cells can carry a “memory” of their past environments—passing it down through generations—before eventually forgetting. Using a new technique called Microcolony-seq, scientists uncovered hidden subpopulations inside infections, each with different survival strategies. The finding could explain why antibiotics and vaccines sometimes fail—and may point the way toward more precise treatments.

Researchers have discovered that a virus living inside the fungus Aspergillus fumigatus significantly boosts the fungus’s ability to survive stress and cause severe infections in mammals. Removing the virus made the fungus weaker and less virulent, while antiviral treatments improved survival outcomes. This finding reveals a hidden factor driving the deadliness of fungal infections and opens the door to potential new treatments that target the virus rather than the fungus itself.

A new cross-national study reveals that older adults with disabilities are significantly less likely to receive preventive care, such as flu vaccinations, eye exams, and dental checkups. This gap remains the same for eye exams and dental care but  is eliminated for flu vaccinations in countries that invest more in public healthcare.

In the weeks after the October 7 Hamas attacks, many Israelis faced not only the trauma of war but also a surge of online hate. A new study from the Hebrew University finds that frequent exposure to such digital vitriol is linked to higher PTSD symptoms, especially for those who struggle to regulate their emotions, underscoring how today’s conflicts can wound both on the battlefield and on the screen.

When survivors of the October 7th attacks returned to what was left of their homes, many carried with them more than grief or post-traumatic stress. A new study shows that the trauma also fueled an unexpected surge in obsessive-compulsive disorder, offering the first direct evidence that acute trauma can trigger the disorder’s onset.
