MIT researchers have introduced a quantum computing architecture that can perform low-error quantum computations while also rapidly sharing quantum information between processors. The work represents a key advance toward a complete quantum computing platform.
Scientists have discovered a new way of killing the bacteria that cause tuberculosis (TB), using a toxin produced by the germ itself.
Scientists led by astronomers at the University of Sydney and Carnegie Observatories have found the remnant of strange dismembered globular cluster at the edge of the Milky Way, upending theories about how heavy elements formed in early stars.
An Italian-American research conducted by researchers at the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology) in Rovereto (Italy) and Harvard University in Boston (Usa) explains for the first time the mechanisms used by our brain to recognize specific smells. Thanks to this result, researchers will be able to think about the realization of an artificial sense of smell, to be transferred to robots and other intelligent machines in the future.
Nanoengineers at UC San Diego developed a new method to fabricate perovskites as single-crystal thin films, which are more efficient for use in solar cells and optical devices than the current state-of-the-art polycrystalline forms of the material. Their fabrication method--which uses standard semiconductor fabrication processes--results in flexible single-crystal perovskite films with controlled area, thickness, and composition.
Mussels secrete sticky plaques that help them attach to wet surfaces, such as rocks on the beach. These adhesive structures are rich in iron, which is thought to help make the attachments strong yet flexible. Now, researchers reporting in Environmental Science & Technology have shown that mussels form weaker attachments in iron-deficient seawater, revealing a possible consequence of altered iron bioavailability in oceans.
Once found in bottles, food containers, cash register receipts and electronics, bisphenol A (BPA) has been phased out of many products because of health concerns and government regulations. As a result, the production and use of BPA analogs, which are unregulated and poorly understood, have increased. Now, by analyzing urine samples and wastewater, researchers report in ACS' Environmental Science & Technology how human exposure to bisphenols has changed over time in an Australian population.
Per- and polyfluoroalkyl substances (PFAS), found in many household products and food packages, have raised concerns because of their persistence and possible toxicity to people and wildlife. Because the compounds don't break down naturally, they have become environmental contaminants. Now, researchers reporting in ACS' Environmental Science & Technology have studied the transport of 29 PFAS into and out of the Arctic Ocean, detecting a newer compound for the first time in Arctic seawater.
Two non-invasive chemical imaging modalities were employed to help understand the changes made over time to the Lamb of God, the focal point of the Ghent Altarpiece (1432) by Hubert and Jan Van Eyck. Two major results were obtained: a prediction of the facial features of the Lamb of God that had been hidden beneath non-original overpaint dating from the 16th century (and later), and evidence for a smaller earlier version of the Lamb's body with a more naturalistic build.
In future, paraffin wax could help to make underground thermal storage units more durable. Such systems are used, for example, to store solar energy over a longer period of time. In a new study, geologists from Martin Luther University Halle-Wittenberg (MLU) investigated the extent to which paraffin wax can be incorporated into the shell of the storage tanks and whether this can prevent heat loss and close fissures. The research team reports on its findings in the journal 'PLOS ONE'.
