On June 1, Mawar (known as Ambo in the Philippines) had maximum sustained winds near 45 knots and it was about 245 miles east-northeast of Manila, Philippines. On that day, as Mawar continued north, some warnings were posted for the Philippines: Public storm warning signal #1 was up in the Luzon provinces of Catanduanes, Camarines Sur, Camarines Norte, Polillo Island, Aurora, Isabela and Cagayan.
This daylight view of the category three typhoon shows that Mawar had a distinct eye on June 4, 2012, before high clouds began to cover it. A rainfall analysis from TRMM's Microwave Image (TMI) and Precipitation Radar (PR) instruments shows a large area of heavy rainfall in the eastern side. TRMM shows that the northwestern quadrant of the typhoon was drier with very little rainfall occurring in that area. TRMM also shows that a very intense line of heavy rainfall was being fed into the southeastern side of the typhoon. The area of moderate to heavy rainfall appears in red, where rain is falling at over 2 inches/50 mm per hour. Light to moderate rainfall was falling at a rate between .78 inches and 1.57 inches per hour (20 to 40 mm). Credit: NASA/TRMM/SSAI, Hal Pierce
On June 2, more warnings were posted in the Philippines. They include: Public storm warning signal #1 in the Luzon provinces of Isabela and Cagayan including Babuyan Island; and Public storm warning signal #2 was in effect in the Luzon areas of Batanes Group of Islands and Calayan Island.
According to Sunstar news, Manila, the National Disaster Risk Reduction and Management Council (NDRRMC) said that 9 people were injured in Natonin, Mt. Province after their car fell into a ravine. Two others were injured from a landslide. Elsewhere, several people were reported missing.
By June 2, Mawar was already departing the Philippines and was 500 miles south-southwest of Kadena Air Base, Okinawa as its maximum sustained winds reached 80 knots (92 mph/148.2 kph) and it was classified a typhoon. Mawar intensified to typhoon strength when it was about 160.9 km (~100 miles) from Luzon. Flooding from Mawar caused at least three deaths in the Philippines even though the typhoon didn't make landfall.
It later grew in strength to 95 knots (109.3 mph/180 kph), and maintained strength as it headed northeast, until 2100 UTC on June 3, when it was being battered by wind shear. At that time, maximum sustained winds dropped back to 80 knots (92 mph/148.2 kph).
By June 4, 2012 at 1500 UTC (10 a.m. EDT) wind shear had relaxed from battering Mawar and its maximum sustained winds increased back up to 90 knots (103.6 mph/166.7 kph). Tropical-storm-force winds extended out from the center as far as 155 miles (249.4 km), making the storm over 300 miles (499 km) in diameter. The typhoon-force winds, however, we confined to 35 miles (56.3 km) out from the center (about 70 miles in diameter). It was near 23.3 North and 127.4 East, about 185 miles south of Kadena Air Base, Okinawa Mawar continued moving north-northeast near 10 knots (11.5 mph/18.5 kph) and it was generating very rough seas, with wave heights reaching 34 feet (10.3 meters)!
A daylight view from NASA's Tropical Rainfall Measuring Mission (TRMM) satellite showed Mawar had a distinct eye on June 4, 2012 before high clouds began to cover it. A rainfall analysis from TRMM's Microwave Image (TMI) and Precipitation Radar (PR) instruments showed a large area of heavy rainfall in the eastern side. TRMM shows that the northwestern quadrant of the typhoon was drier with very little rainfall occurring in that area. TRMM also showed that a very intense line of heavy rainfall was being fed into the southeastern side of the typhoon.
Satellite imagery also showed that convection (rising air that forms the thunderstorms that make up the storm) and thunderstorms are disorganized. In addition, wind shear appears to be returning and the storm appears to be elongating. Atmospheric conditions are now becoming increasingly hostile and the storm will continue to weaken. Forecasters expect Mawar will become an extra-tropical storm south of Japan by mid-week.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.

Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
