An image from NOAA's GOES-West satellite on Aug. 9 at 1200 UTC (8 a.m. EDT) captured all three tropical systems. The storm farthest west is Hurricane Henriette, followed by System 92E to the east.
NOAA's GOES-15 satellite captured and image of Hurricane Henriette and two trailing and developing low pressure areas in the Eastern Pacific ocean on Aug. 9 at 1200 UTC (8 a.m. EDT).

System 92E is trailed by System 93E even further east. The GOES-West imagery shows that System 92E has a more developed circulation, and the National Hurricane Center gives that low pressure area a much higher chance to develop in the next couple of days than System 93E.The GOES-West image was created at NASA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md.Henriette Losing its Punch
GOES-West imagery showed that Henriette has become more asymmetric, a sign of weakening. Tropical cyclones need to be circular in shape to maintain strength or strengthen. When they begin losing the circular shape, they start to "spin down" and slow down like a tire going flat. Infrared satellite data showed that the thunderstorm cloud top temperatures on the southern side of the storm were warming, indicating cloud heights were dropping. Warmer cloud top temperatures indicate lower storms, which means that they don't have as much uplift or strength in them as they did before.
The Central Pacific Hurricane Center noted that Henriette is expected to weaken to tropical storm force later on Aug. 9 and dissipate by Monday, Aug. 12.System 93E a Slow-Developing Storm

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
