NASA's Aqua satellite passed over Tropical Storm Dokuri on June 27 on 0435 UTC (12:35 a.m. EDT). Infrared data from the Atmospheric Infrared Sounder (AIRS) instrument onboard indicated there were still some strong showers and thunderstorms within the system. Those cloud top temperatures were colder than -63 Fahrenheit (-52 Celsius), indicating strong uplift in the atmopshere, and thunderstorms within Dokuri that have the capability for heavy rainfall.

Infrared data shows a fully-exposed low level-circulation center. The strongest convection (rising air that creates thunderstorms that make up the system)are being pushed to the southwest due to strong northeasterly vertical wind shear.
Warnings are up in the Philippines as Doksuri (known there as Dindo) continues to move north of Luzon today. Public storm warning signal #1 is in effect in Abra, Kalinga, Isabela, Ilocos Sur, Mt. Province, Ifugao, La Union, Benguet, Pangasinan, Nueva Vizcaya and Quirino. Public storm warning signal #2 is also in effect for Cagayan, Calayan Group of Islands, Babuyan Group of Islands, Batanes Group of Islands, Apayao, Ilocos Norte.
On June 28, 2012 at 1500 UTC (11 a.m. EDT), Tropical Storm Doksuri had maximum sustained winds near 35 knots. It was located approximately 335 nautical miles north of Manila, Philippines, near 20.4 North and 120.7 East. It was moving to the west-northwestward at 17 knots. The strongest convection and thunderstorms were located over northern Luzon at this time, and are moving off the northwestern coast of the Philippines.
Doksuri has weakened as it passes to the north of Luzon. Doksuri is expected to continue tracking west and make landfall near Hong Kong in two days.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
