A water tank concealed below the eastern patio, cork insulation inside the walls, and a drainage system hidden in the columns of the pool – these are just a few of unique features uncovered as Weizmann House underwent an extensive restoration and conservation process over the past year. The house has now reopened to the public. More than 80 years after it was built, the house of the first president of the State of Israel – designed by Erich Mendelsohn, one of the giants of modern architecture – continues to garner interest around the world. In parallel with its reopening to the public, the international organization Iconic Houses chose to add Weizmann House to its ranks. This makes Weizmann House the first building in Israel to become a part of this network, joining such modern architectural wonders as Fallingwater, designed by Frank Lloyd Wright; Vila Tugentdat of Ludwig Mies van der Rohe; and another 150 houses around the world.

Israel is subjected to sand and dust storms from several directions: northeast from the Sahara, northwest from Saudi Arabia, and southwest from the desert regions of Syria. The airborne dust carried in these storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms. Some of these bacteria might be pathogenic – harmful to us or the environment – and a few of them also carry genes for antibiotic resistance.

Gihon Spring, just downhill from the ancient city of Jerusalem, was crucial to the survival of its inhabitants, and archaeologists had uncovered the remains of a massive stone tower built to guard this vital water supply. Based on pottery and other regional findings, the archaeologists had originally assigned it a date of 1,700 BCE. But new research conducted at the Weizmann Institute of Science provides conclusive evidence that the stones at the base of the tower were laid nearly 1,000 years later.

More than 400 years after Galileo turned his telescope toward the planet Jupiter, the clouds and mist covering this giant of our Solar System are beginning to disperse. Since 1973, no fewer than six spacecraft have flown by Jupiter. But the Juno probe, launched in 2011 and in orbit around the planet since July 2016, is the first one equipped with systems that are able to reveal the secrets of Jupiter’s inner structure beneath the thick clouds.

Bread occupies a unique place in our diet: it accounts for about one-tenth of the calories many people in the West consume and up to 40 percent of the caloric consumption in some non-Western countries – more than any other food product. In the past few decades, since white bread has acquired a bad name, bakeries have been going out of their way to produce high-quality whole grain breads. But a new study conducted at the Weizmann Institute of Science and published recently in Cell Metabolism reveals that these “wholesome” choices are not necessarily the healthiest for everyone.

The tiny cone-shaped “skimmers” used in experiments looking for exotic chemical-quantum phenomena resemble the intake mechanisms of aircraft engines, and they perform similar functions: each directs the flow of gas – the engine intake controls the supply of air for burning fuel, and the “skimmer” creates beams of cold flying atoms or molecules. While skimmers have been a necessary component in atomic and molecular-beam experiments for decades, they were also known to impose a fundamental limit on the number of particles one could pack into the beam.

Alzheimer’s disease is a neurodegenerative disease manifested by various neuronal pathological processes and a significant decline in brain function. Aggregates of beta-amyloid protein (“plaques”) accumulate within and between brain cells. Due to both structural changes and the weakening of chemical communication pathways, the junctions of neuronal networks (synapses) are lost. In addition, the cytoskeletal proteins of the axons lose their normal structure, impairing their function and causing massive neuronal death.

Heart disease remains the leading cause of death worldwide, yet the few available treatments are still mostly unsuccessful once the heart tissue has suffered damage. Mammalian hearts are actually able to regenerate themselves and repair damage – but only up to around the time of birth. Afterward, that ability disappears, seemingly forever.

Stress affects the body and can trigger illness – from psychiatric disorders to heart disease. Humans are exposed to stress at different intensities throughout life: as children, in adolescence, and in old age. But when is the impact of stress on our systems most powerful? Many researchers maintain that the critical effect occurs prenatally, inside the womb. This hypothesis was, until recently, based mainly on statistical data indicating a correlation between stress during pregnancy and susceptibility to disease.
