A new MIT-developed technique enables robots to quickly identify objects hidden in a three-dimensional cloud of data, reminiscent of how some people can make sense of a densely patterned "Magic Eye" image if they observe it in just the right way.

Discovery of the cell fate switch from neurons to astrocytes in the developing brain
During mammalian brain development, neural precursor cells first generate neurons and later astrocytes. This cell fate change is a key process generating proper numbers of neurons and astrocytes. Here we discovered that FGF regulates the cell fate switch from neurons to astrocytes in the developing cerebral cortex using mice. FGF is a critical extracellular regulator of the cell fate switch, necessary and sufficient, in the mammalian cerebral cortex.

Cytotoxicity and physical properties of glass ionomer cement containing flavonoids
At the 97th General Session & Exhibition of the International Association for Dental Research (IADR), held in conjunction with the 48th Annual Meeting of the American Association for Dental Research (AADR) and the 43rd Annual Meeting of the Canadian Association for Dental Research (CADR), Aline de Castilho, University of Campinas, Brazil, presented a poster on "Cytotoxicity and Physical Properties of Glass Ionomer Cement Containing Flavonoids." The IADR/AADR/CADR General Session & Exhibition is held at the Vancouver Convention Centre West Building in Vancouver, BC, Canada from June 19-22, 2019.

Fungus produces highly effective surfactant
Mortierella alpina lives in the soil and likes to keep cool. This fungus, which belongs to the zygomycetes, grows best at temperatures of 10 to 15 degrees C and occurs mainly in alpine or arctic habitats. In biotechnology, the fungus has been used for the large-scale production of polyunsaturated fatty acids such as arachidonic acids, mainly as a dietary supplement in baby foods.

Scientists map huge undersea fresh-water aquifer off US Northeast
In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean. It appears to be the largest such formation yet found in the world. The aquifer stretches from the shore at least from Massachusetts to New Jersey, extending more or less continuously out about 50 miles to the edge of the continental shelf. If found on the surface, it would create a lake covering some 15,000 square miles. The study suggests that such aquifers probably lie off many other coasts worldwide, and could provide desperately needed water for arid areas that are now in danger of running out.

Marshall Islanders 'sitting ducks' as sea level rises, says president

Bacteria live on our eyeballs—and understanding their role could help treat common eye diseases
You may be familiar with the idea that your gut and skin are home to a collection of microbes—fungi, bacteria and viruses—that are vital for keeping you healthy. But did you know that your eyes also host a unique menagerie of microbes? Together, they're called the eye microbiome. When these microbes are out of balance—too many or too few of certain types—eye diseases may emerge.

Dental microwear provides clues to dietary habits of lepidosauria
High-resolution microscopic images of the surface of dental enamel of lepidosauria, which is a subclass of reptile including monitor lizards, iguanas, lizards and tuatara, allow scientists to determine their dietary habits. The enamel wear patterns reveal significant differences between carnivores and herbivores, but also allow finer distinctions, such as between algae-, fruit-, and mollusk-eating species. These findings are the result of research by a team led by scientists at Johannes Gutenberg University Mainz (JGU). They point out that it has hitherto been difficult to make such fine distinctions between dietary behavior on the basis of dental or skeletal remains alone, particularly in the case of extinct species, because in many reptiles the teeth are of similar shape.

Researchers report annual variability of ice-nucleating particle concentrations at different Arctic locations
For the first time, an international research team led by the Leibniz Institute for Tropospheric Research (TROPOS) has investigated atmospheric ice-nucleating particles (INPs) in ice cores, which can provide insights on the type of cloud cover in the Arctic over the last 500 years. These INPs play an important role in the formation of ice in clouds, and thus have a major influence on the climate. So far, however, there are only a few measurements that date back only a few decades. The new method could provide information about historical clouds from climate archives and thus close large gaps in knowledge in climate research.

Imaging results, health data combine in AI model to predict breast cancer
Women know the drill: Breast cancer is too commonly a cancer diagnosis to be ignored, as early detection could make a difference. While false positives may cause an enormous amount of undue stress, false negatives have an impact on how early a cancer is detected and subsequently treated.
