In shaky times, focus on past successes, if overly anxious, depressed
The more chaotic things get, the harder it is for people with clinical anxiety and/or depression to make sound decisions and to learn from their mistakes. On a positive note, overly anxious and depressed people's judgment can improve if they focus on what they get right, instead of what they get wrong, suggests a new University of California, Berkeley, study.

Tiny nanospindles enhance use of ultrasound to fight cancer
Ultrasound can be used to treat cancer when used in combination with molecules that sensitize the system to sound waves. These sonosensitizers generate toxic reactive oxygen species that attack and kill tumor cells. In Applied Physics Review, scientists report a new type of sonosensitizer based on a vanadium-doped titanium dioxide that enhances the amount of damage ultrasound inflicts on tumors. Studies in mice showed tumor growth was markedly suppressed when compared to a control group. (2020-12-08)

Stanford engineers combine light and sound to see underwater
''Airborne and spaceborne radar and laser-based, or LIDAR, systems have been able to map Earth's landscapes for decades. Radar signals are even able to penetrate cloud coverage and canopy coverage. However, seawater is much too absorptive for imaging into the water,'' said study leader Amin Arbabian, an associate professor of electrical engineering in Stanford's School of Engineering. ''Our goal is to develop a more robust system which can image even through murky water.'' (2020-11-30)

Dark matter from the depths of the universe
Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble signals detectable with quantum sensor networks such as the atomic clocks of the GPS network or the magnetometers of the GNOME network. These results are particularly interesting in the context of the search for dark matter, as low-mass fields are regarded as promising candidates for this exotic form of matter. (2020-11-11)

New medication to treat shock caused by blood or fluid loss found safe and effective
Hypovolemic shock, caused by severe loss of blood or body fluids, can be deadly if not treated promptly. Centhaquine is a new medication for the treatment of hypovolemic shock that increases blood flow to the heart and organs to prevent organ failure and death. It is still in clinical trials in the U.S. Results from a small, randomized, placebo-controlled trial in India found that centhaquine significantly improved blood pressure, blood lactate levels and reduced death rate when added to standard treatment.
