A new direction for drugs that will slow down the development of Parkinson's

Researchers from the Hebrew University and Penn State University revealed for the first time the structures of the central protein in the early stages of Parkinson's disease. Dr. Eitan Lerner: "The findings may help in the development of drugs that will help slow the pace of the disease and possibly even prevent it"

Population explosion of fish species in the Mediterranean as a result of a massive invasion of Red Sea fish

A new study carried out by marine biologist Dr. Danny Golani of the Hebrew University states that 469 species of fish are wading in Israel's Mediterranean waters today, with a record number of 32 new species having migrated to them from the Red Sea in the last 15 years. Migration due to climate change? Don't count on it. The result, among other things: poisonous fish and poisonous fish are multiplying and establishing themselves these days near the shores of Israel

Traces of the radioactive plutonium were found in a deep-sea mineral in the Pacific Ocean, which is a millions-year-old archive of material from the Earth but also of cosmic dust that settles on it

How does a potato feel?

Researchers from the Faculty of Agriculture developed biological sensors in potatoes through genetic engineering, which warn in real time about the distress of the plant

A shadow of truth: thanks to a groundbreaking study published in Science - quantum entanglement emerges from the shadows

The researchers were able to directly observe the entangled quantum state of two mechanical drums, each with a size close to the diameter of a human hair.

A new method makes it possible to map desert lakes around the world from space

Prof. Moshe Armon: "The method we developed can be used to map the bottom of desert lakes around the world, and help us understand what the climate was like in those regions of the world in the past and maybe even in the future."

A huge international study strengthens the connection between corona and stroke in young people who have fallen ill

  • One response
In the study, in which researchers from Israel, the USA, Canada, Australia, Egypt, Iran, Lebanon and the United Arab Emirates participated, blockages of large blood vessels were mainly found in the brains of the young subjects

A virus from the corona family that affects horses was diagnosed for the first time in Israel

The equine corona virus is a close relative of the corona virus which has caused widespread morbidity in the world in the last year (COVID-19). In this family, called beta-coronavirus, there are also other animal and human corona viruses, among them the bovine corona, which is also found in cattle in Israel

gene drive makes it possible to quickly change traits of different species. Now they are looking for a way to control the process

New technologies in the field of genetic engineering today allow us to change the properties of different species quickly and with great flexibility, for example controlling the reproductive capacity of pests, but are they safe?

The effect of the types of lighting on the reproductive systems of chickens. The image was prepared by DALEE and is not a scientific image

The reproductive performance of roosters improves according to the changes in the lighting color

It turns out that artificial lighting plays a central role in the reproductive processes of poultry. Prolonged exposure to light in a red wave absorbed through the extraretinal receptors while suppressing the activation of retinal photoreceptors has a positive effect on the reproductive capacity of chickens. The study was published in the journal Poultry Science.

The intentional settlement in the oldest caves in the world has been found

Researchers from the Hebrew University and the University of Toronto found that the ancient hominids settled in caves and began making tools as early as 1.8 million years ago in South Africa: "The study reliably confirms and establishes our previous estimates regarding the ages of the first settlement in the cave, the changes in stone tool production technologies and the first deliberate use of fire "

Monkeys also have consciousness (and subconscious)

A joint study by researchers from the Hebrew University and Yale University makes it possible for the first time to examine whether awareness and unconscious processes should be lived.

Ayalon Cave, where very rare species of beavers live, is on the brink of an ecological disaster

Prof. Frumkin: "In a proper step, albeit a bit late, some of the animal species from the cave were also included in it (only the species living in the cave's aquatic environment). This helps in preserving the cave, but without declaring the cave and its surroundings as an official nature reserve, it will be difficult to enforce the law."

Rethinking Jacob and Esau: a new study proves that fights between twins do not affect the degree of sacrifice between them

A new study in the Department of Psychology at the Hebrew University sheds light on the complexity of the relationship between twins, and also examines how parenting affects these relationships. This is the most comprehensive study done regarding the relationship between twins throughout childhood

New research resolves a long-standing controversy regarding the taste of heavy water

A unique study at the Hebrew University found that heavy water is distinctly sweeter than regular water, and may even mask a slight bitterness.

Following the corona crisis, many want to recycle more and consume less

Researchers conducted a survey among 400 respondents who are residents of Israel, which examined patterns of sustainable behavior - such as frequency of recycling, reducing consumption and a consumer strategy that leads to reducing environmental effects - before the outbreak of the Corona crisis, during the first lockdown, and the respondents' intentions for the future. In addition, the extent to which the respondents link the outbreak of the epidemic with the state of the environment and climate change was examined

What is the mysterious vision problem that blinds octopuses?

"Examining the eyes of octopuses requires complete anesthesia by adding anesthetics to the water and adapting the test instruments intended for testing on land to testing in a marine environment. Add to this the structure of the eyes of octopuses which is significantly different from the eyes of mammals and testing them is a difficult procedural procedure."

A team of researchers from the Department of Biochemistry, Food Sciences and Nutrition at the Faculty of Agriculture of the Hebrew University, examined for the first time ever the effect of the ultra-processed food on the development of the skeleton

Researchers returned a genetic segment of the wild wheat to modern wheat and improved the efficiency of the root system

Wild wheat, "the mother of wheat", is one of the first plants that man domesticated about ten thousand years ago. Over the years, as a result of accelerated cultivation to improve crops, many essential traits that are retained in the wild species have been displaced from modern wheat. Among the repressed traits, there are anatomical and physiological characteristics of the root system that have a dramatic effect on the water balance of the entire plant

Could the development of the CIT test (with an AI algorithm) replace the polygraph in the near future?

The results of the experiment show that brain reactions of suspects can be analyzed using an algorithm in real time, with great accuracy, even when there is an effort on the part of the subject to hide the information. The researchers are sure that the new method was able to solve historical crime mysteries such as the Damianiuk affair

New research reveals how a predatory bacterium can be curbed

Prof. Emmanuel Hansky from the Hebrew University, heads a team of joint research conducted in Singapore and Israel. The team published a study in the prestigious journal Cell Reports: "This study provides a precise understanding of the interactions between the Streptococcus type A bacterium and the host, and improves the ability to design effective treatments against it, such as engineered peptides that the bacterium cannot cleave."

Constipation and contraction of brain cells - the key to an early diagnosis of Parkinson's disease?

In a study led by Prof. Yehoshua Goldberg from the Hebrew University, it was found that the contraction of brain cells may explain the constipation symptom among Parkinson's patients. The important finding is expected to help in the future in the diagnosis of Parkinson's disease already in its early stages
