Conson, known locally in the Philippines as "Tropical Storm Basyang," was about 400 nautical miles east of Manila, Philippines, near 14.4 North and 127.1 East at 1500 UTC (11 a.m. EDT). Conson has maximum sustained winds near 60 knots (69 mph) with higher gusts. Although Tropical Storm Conson is moving west near 14 knots (16 mph) it is forecast to track north-northwest over the next couple of days, and is expected to make landfall on July 13 after 1200 Zulu Time (8 a.m. EDT or 8 p.m. local Asia/Manila time).
The Philippine Atmospheric Geophysical and Astronomical Services Administration known as PAGASA posts forecasts and watches and warnings for residents of the Philippines.
Signal Warnings have been posted by PAGASA for various areas in Luzon, the Philippines. Signal No. 2 has been posted in Luzon for the following areas: Catanduanes, Camarines Norte, Polillo Island, Aurora, Quirino and Isabela. Signal 2 means winds are expected between 60-100 kph (37-62 mph).
A Signal No. 1 alert indicates expected winds between 30-60 kph (18-37 mph). A Signal 1 is in effect in Luzon for the areas of: Camarines Sur, Albay, Quezon, Rizal, Bulacan, Nueva Ecija, Nueva Vizcaya, Ifugao, Benguet, Mt. Province, Kalinga, and Cagayan. Residents living in low lying and mountainous areas under signals # 1 and 2 are alerted against possible flashfloods and landslides.

PAGASA indicated that by Tuesday evening (local Asia/Manila time) the center of Conson (or Basyang) should be located about 90 km (55 miles) east of Casiguran, Aurora and is expected to make landfall before midnight (local time). By Wednesday evening, July 14, Conson's (Basyang) center is expected to be about 120 km (74 miles) west-Southwest of Laoag City.
Microwave satellite imagery on July 12 (today) indicated a low-level eye feature, a sign that Tropical Storm Conson may be strengthening into a Cyclone. Even though today's visible image captured by the Moderate Resolution Imaging Spectroradiometer (that flies aboard NASA's Aqua satellite) did not show an eye, it was likely because the upper levels of Conson's center were obscured by high clouds.
Forecasters at the Joint Typhoon Warning Center indicate that Conson will continue to strengthen because it is in an area with low vertical wind shear (winds that can tear a storm apart if strong enough) and warm sea surface temperatures (that power cyclones).

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
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...
