Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in the field of nanoscience by successfully altering nanocrystal properties with impurity atoms -- a process called doping "“ thereby opening the way for the manufacture of improved semiconductor nanocrystals. Semiconductor nanocrystals consist of tens to thousands of atoms and are 10,000 times smaller than the width of a human hair. These tiny particles have uses in a host of fields, such as solid-state...

Says Hebrew University researcher A pathway whereby bacteria communicate with each other has been discovered by researchers at the Hebrew University of Jerusalem. The discovery has important implications for efforts to cope with the spread of harmful bacteria in the body. Bacteria are known to communicate in nature primarily via the secretion and receipt of extracellular signalling molecules, said Prof. Sigal Ben-Yehuda of the Institute for Medical Research Israel-Canada (IMRIC) at the Hebrew...

Researchers from the Hebrew University of Jerusalem and the US have discovered the mechanism whereby dangerous mercury eventually finds its way into the fish we eat from the open seas and oceans. The researchers, Prof. Menachem Luria from the Fredy and Nadine Herrmann Institute of Earth Sciences at the Hebrew University and Dr. Daniel Obrist of the University of Nevada, found that "passive" mercury normally found in the atmosphere is converted into an "active," oxidized form in the presence...

Report Hebrew University, French researchers The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study by researchers from the Hebrew University of Jerusalem and France. Brain imaging studies of blind people as they read words in Braille show activity in precisely the same part of the brain that lights up when sighted readers read. The findings challenge the textbook notion that the brain is divided up into regions that are specialized for...

A low cost, nanometer-sized drug to treat chronic wounds, such as diabetic foot ulcers or burns, has been developed by a group of scientists from the Hebrew University of Jerusalem, Harvard Medical School and others in the U.S. and Japan. Diabetes is a rapidly growing medical problem affecting close to 3 percent of the world's population. Poor blood circulation arising from diabetes often results in skin wounds which do not heal, causing pain, infection and at times amputation of limbs....

Research carried out at the Hebrew University of Jerusalem shows that it was possible already in 2008 to predict that countries such as Egypt and Iran were headed for dangerous periods of instability because of citizens' demands for democratization. The researchers were able to make this observation on the basis of a "democratic gap" scale of measurement between the level of freedom existing and the desire of citizens for more freedom, which was analyzed in about 90 countries around the...

Global warming is already affecting the earth in a variety of ways that demand our attention. Now, research carried out at the Hebrew University of Jerusalem indicates that many tree species might become extinct due to climate change if no action is taken in time. According to the research, trees which disperse their seeds by wind, such as pines and maples, will be unable to spread at a pace that can cope with expected climate changes. The research, which focused on the ecological...

Based on quantum mechanics theory With the current outbreak of the flu season in Israel, hospitals are reporting overcrowding, and doctors are advising people who have not yet been vaccinated against flu to get their shots. Surprisingly, however, three physicists -- one from the Hebrew University of Jerusalem and two others from the University of Michigan "“ have developed an unconventional, theoretical strategy for intensive but limited vaccination against infectious diseases (such as...

Large birds, such as storks, save energy on the flight to their wintering grounds by soaring through the air on thermal currents. Until now, however, we knew nothing about the flight patterns of small migrating songbirds, such as whether they flap their wings or soar and whether these styles of flight allow them to save energy. Now, a team of scientists at the Max Planck Institute for Ornithology in Radolfzell, Ben-Gurion-University of the Negev, and Hebrew University of Jerusalem have...

Research work carried out at the Hebrew University of Jerusalem arouses a cautionary warning in the growing field of the development of stem cells as a means for future treatment of patients through replacement of diseased or damaged tissues by using the patient's own stem cells. The research indicates a possible danger of cancerous tissue development in the use of such cells. Embryonic stem cells, which are undifferentiated cells, have the potential to develop into all cell types of the...
