AFRL completed a two-year space experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.

WASHINGTON — The U.S. Air Force Research Laboratory announced July 19 it has completed a two-year experiment that will help better understand the effects of radiation on space hardware in medium Earth orbit.

Known as the Demonstration and Science Experiments (DSX) mission, the spacecraft was one of 24 payloads launched June 25, 2019, on a SpaceX Falcon Heavy rideshare.

Researchers warn of the potential social, ethical, and legal consequences of technologies interacting heavily with human brains.

Surpassing the biological limitations of the brain and using one’s mind to interact with and control external electronic devices may sound like the distant cyborg future, but it could come sooner than we think.

Researchers from Imperial College London conducted a review of modern commercial brain-computer interface (BCI) devices, and they discuss the primary technological limitations and humanitarian concerns of these devices in APL Bioengineering, from AIP Publishing.

To date, there are no effective antidotes against most virus infections. An interdisciplinary research team at the Technical University of Munich (TUM) has now developed a new approach: they engulf and neutralize viruses with nano-capsules tailored from genetic material using the DNA origami method. The strategy has already been tested against hepatitis and adeno-associated viruses in cell cultures. It may also prove successful against corona viruses.

This month, Stanford researchers brought us one step closer to artificial skin with embedded electronics that can flex and bend with the body.

Magnetic shields could help earth if we lost out outer shielding from atmosphere and stuff.

The space agency is considering an artificial magnetic field around the planet to defend against harmful radiation from the sun.

“Our studies in mice revealed how genes co-operate to cause cancer in different organs. We identified main players, the order in which they occur during tumor progression, and the molecular processes how they turn normal cells into threatening cancers. Such processes are potential targets for new treatments”.

Why do alterations of certain genes cause cancer only in specific organs of the human body? Scientists at the German Cancer Consortium (DKTK), the Technical University of Munich (TUM), and the University Medical Center Göttingen have now demonstrated that cells originating from different organs are differentially susceptible to activating mutations in cancer drivers: The same mutation in precursor cells of the pancreas or the bile duct leads to fundamental different outcomes. The team discovered for the first time that tissue specific genetic interactions are responsible for the differential susceptibility of the biliary and the pancreatic epithelium towards transformation by oncogenes. The new findings could guide more precise therapeutic decision making in the future.

There have been no major improvements in the treatment of pancreatic and biliary tract cancer in the last decades and no effective targeted therapies are available to date. “The situation for patients with pancreatic and extrahepatic bile duct cancer is still very depressing with approximately only 10% of patients surviving five years,” says Dieter Saur, DKTK Professor for Translational Cancer Research at TUM’s university hospital Klinikum rechts der Isar, DKTK partner site Munich.

GaAs-based terahertz quantum cascade lasers emitting around 4 THz are demonstrated up to 250 K without a magnetic field. To elevate the operation temperature, carrier leakage channels are reduced by carefully designing the quantum well structures.
