Researchers from the University of Cambridge found in Scientific Reports that comets hit Earth too fast and at too steep an angle. Therefore, hydrogen cyanide, a molecule important to the chemistry that preceded life, probably vaporized upon impact.

How does a drop roll on a superhydrophobic surface? An explanation of Yariv and Schnitzer's research, published in 2019–2023, and the mathematical solutions for droplet motion and shape.

Researchers led by ETH Zurich have developed an implant that converts blood glucose into a substance excreted in the urine, and is automatically activated by a sugar sensor. In obese mice with type 2 diabetes, it returned sugar levels to normal within an hour.

A study in Nature analyzed genetic data from about 2.8 million people, including 183,620 Alzheimer's patients. The researchers identified 127 regions of DNA associated with risk of the disease, and the findings point to microglia and certain types of nerve cells.

The British actor, who played Captain Jean-Luc Picard in "Star Trek: The Next Generation" and Professor Charles Xavier in the "X-Men" films, died at his home in Los Angeles after a short battle with Alzheimer's and dementia with Goofy Levy.

A study in mice from the Hebrew University found that preserving blood vessels using the protein VEGF extended life expectancy by 20% and slowed down aging processes and diseases.

A 99-million-year-old lizard tail in amber provides the first direct fossil evidence that a lizard shed its tail voluntarily. Tel Aviv University researchers found in it the muscle markings characteristic of tail shedding in modern lizards.

Limestone rocks in southern China reveal that in the 1.7 million years before the end-Guadalupian extinction, Earth's magnetic field reversed about 11 times every million years, well above average. The researchers emphasize that this is not proof that the field caused the extinction.

An international team with the participation of the Weizmann Institute has built a molecular Archimedes screw: a single helical molecule that rotates when an electric current passes through it. As it rotates, its conductivity can increase by up to 100 times.

Can good news about a competing company lower the stock price of another company? A game theory model from the Hebrew University examines how investors interpret information from an external source.

An analysis of more than a million forecasts across four platforms shows that prediction markets estimate probabilities well on average. However, in military conflicts, international relations, and technology, they overestimate, and in elections, they underestimate.

Nir Minervi, CEO of the Israeli quantum software company Classic, which was acquired by Intel, answers Hayadan's question about the unfulfilled promises, explains where the quantum computer will fit alongside regular processors and artificial intelligence, and admits: "Quantum computing currently brings no commercial applied value to anyone."

In a vision task tested in monkeys for decades, crows made a decision in about 235 milliseconds on average, about twice as fast as reported for monkeys, without sacrificing accuracy.

The Jewish biochemist, the first woman elected to the Soviet Academy of Sciences, was arrested in the Jewish Anti-Fascist Committee affair. Her interrogation protocols reveal a scientist who did not deny her Jewishness or give up the independence of science.

Researchers at Sheba and Tel Aviv University have grown hundreds of fetal kidney models from amniotic fluid. The goal: to understand and treat kidney defects while still in the womb.

Physicists at Northwestern University have trapped a single positron, the antimatter equivalent of the electron, cooled it to its quantum ground state and kept it in a trap for months. The goal: the most precise test yet of the symmetry between matter and antimatter.

Can a lottery ticket convince us to put down our phones? Dr. Yefim Roth from the University of Haifa examines how much screen time can be saved with a small incentive.

Aircraft measurements over the Amazon from 2010 to 2024 show that the region emitted an average of 1.17 billion tons of carbon dioxide per year more than Chile. According to the researchers, the main cause is fires and deforestation, which are intensifying in droughts.

Two black holes can collide and merge into one. A new theoretical study examines whether the opposite could also happen. According to calculations, the laws of thermodynamics almost close the door, but maybe not completely.

Prof. Avraham Gover of Tel Aviv University is investigating how electrons with a coherent wave function amplify light radiation, and how they can transfer an energetic "boost" to an electron trapped in an atom.

The recycling rate has dropped, scientific achievements are at a low point, the space budget has shrunk according to an N12 investigation, and research centers in the periphery have been waiting for pay. A summary of the Hayadan series on the functioning of government ministries related to science, education, and the environment, on a day when the public decides.

An analysis of 243 ancient genomes from the Iberian Peninsula shows that Roman rule brought about a major demographic shift, with the arrival of people from the eastern Mediterranean and North Africa. The Suevi, Vandals, Alans and Visigoths who came after them contributed only 12% to 22% of the genetic ancestry.

Sydney researchers compared embryo models to a map of gene expression in natural development. The test reveals which cells and processes are well-restored and which are still missing.

In a total lunar eclipse, the Earth blocks the sunlight from the Moon, and the Moon blocks the Sun. A guide to the types of lunar eclipses, why the Moon turns red, what eclipses have taught science, and when the next lunar eclipses will be visible from Israel, including three total eclipses between the end of 2028 and the end of 2029.
