Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the reason for the accumulation of the defective proteins was unknown
Kariko and Weissman immediately realized that their discovery was of enormous significance for the possible use of messenger RNA in medicine. These important findings were published in 2005, 15 years before the outbreak of the Corona epidemic.
Researchers at the Walter and Eliza Hall Institute (WEHI) in Melbourne have solved a long-standing mystery regarding the role of a protein in removing damaged mitochondria from the body. These findings may pave the way for potential new treatments for Parkinson's disease
Researchers have discovered that two epigenetic events (removing and adding methyl from DNA) lead to the differentiation of stem cells into muscle cells and thus to the regeneration and healing of muscles after their injury
A new Israeli study examined the siksak, a common species of bird - and found that urban siksaks are braver than their rural brethren. Although we usually all appreciate this beautiful feature, it is possible that the change in behavior in question is actually not so positive for these birds
In the Gaza Strip there is no law or supervision against fishing for protected species - therefore, sharks and bats that are in danger of extinction are hunted there freely. A new Israeli study presents a method for collecting data from social networks that allows us to map the phenomenon, and find out what is happening in the Gaza Strip
The doctoral thesis of Dr. Liat Hooper from the Department of Social Work and the Faculty of Health Sciences revealed for the first time the existence of gender differences in the health and mental consequences of baldness, as a result of the radiation against ringworm
In addition, the Ministerial Committee for Science and Technology approved: the formulation of a national plan to promote the Blue-Tech field in Israel
One of the most common treatments for bipolar disorder today is the drug lithium - a drug to which only about a third of patients respond. The research aims to understand what causes this
Preeclampsia is a life-threatening multisystem disease and one of the main causes of maternal and fetal mortality. Its global prevalence is about 5% of pregnancies
This new measurement method, developed by PhD student Shir Filo and Prof. Metzer, will allow the extraction of precise biological values on the brain, so that it will be possible to derive from an MRI test similar indicators to those obtained from a blood test or from a brain biopsy
A new study conducted at the University of Haifa found that even the sniper fish, which lack the "higher" areas of the cerebral cortex, which are seen as being responsible for social behavior, act in a pro-social way towards their friends, until they feel "cheated"
The error rate of the existing biopsy tests is 30%. Mistakes that are fatal because the test turns up clay but the cancer exists and continues to spread. Good imaging can improve accuracy
According to Dr. Motty Charter, the fact that two amateur observers are the ones who identified the raccoon, an endangered species, through watching the Charter Group's Birds Online YouTube channel, highlights the enormous importance of citizen science in protecting wildlife.
A pregnancy test detected the fetus in the test tube. The artificial models developed from stem cells - without egg, sperm or uterus - and grew in the laboratory until day 14
