For almost two years, newsfeeds have kept us updated on the daily battle to annihilate the coronavirus.  So, it’ s easy to forget that there are also many types of bacteria threatening human health – our survival depends on the constant quest for new antibiotics that can destroy them.  Recent research provides an important insight into the complex response of bacteria to antibiotics and opens up the possibility of developing a novel and more effective class of drugs to combat major bacterial diseases.

Back in the day, the Assyrians were one of the Near East’s superpowers, controlling a land mass that stretched from Iran to Egypt. They accomplished this feat with military technologies that helped them win any open-air battle or penetrate any fortified city.  While today, air power and bunker busters help win the war, back in the ninth to the seventh centuries BCE, it was all about the siege ramp, an elevated structure that hauled battering ramps up to the enemy’s city walls and let the Neo-Assyrians soldiers wreak havoc on their enemies.

The human brain is a constant buzz of activity, with its 86 billion nerve cells (neurons) sending electrical signals from one region of the brain to another. The signals travel along the white matter fibers, a maze of wire-like fibers, ultimately giving rise to all brain functions. Uncovering these wire-like highways between neurons has been a longstanding challenge for neuroscience.  Existing methods for mapping this neural circuitry at the cellular level are either limited to animal studies or require highly specialized equipment for data acquisition and processing.

In our increasingly industrialized world, what we produce “out there” has a direct impact on what happens inside our bodies.  A new study by the Hebrew University of Jerusalem (HU) reveals the link between rates of metal production and toxic lead exposure in humans.  The research team closely examined human remains from a burial ground in central Italy that was in consecutive use for 12,000 years.

Among 2,000 universities surveyed worldwide, the Hebrew University of Jerusalem (HU) ranked 90^th in the 2021 Academic Ranking of World Universities (ARWU)’s evaluation of higher education institutions.  This marks HU’s best showing since 2016.

Smoking among young teens has become an increasingly challenging and costly public healthcare issue.  Despite legislation to prevent the marketing of tobacco products to children, tobacco companies have shrewdly adapted their advertising tactics to circumvent the ban and maintain their access to this impressionable—and growing—market share. 

A recent archeological dig in central Israel unearthed evidence that Homo sapiens, humans that inhabit the earth today, likely lived alongside a group of archaic humans known as the Middle Pleistocene Homo.  This discovery, and the international collaborations that made it possible, provide the first evidence that the two human types lived at the same time and interacted with one another.  Their findings were published today in Science.

Happiness might lead to better health but does it help you live longer? That’s a question that researchers at the Hebrew University of Jerusalem (HU) took on in a longitudinal study they began back in the 1990s.  They looked at the impact of optimism on longevity and found that maintaining a positive outlook can directly extend your life. Professor Jochanan Stessman, Director of HU’s Institute on Aging led the study, along with HU’s Prof. Jeremy Jacobs and Dr. Yoram Maaravi.  They published their findings in The Journals of Gerontology.
