Under pressure, nontoxic salt-based propellant performs well
In smaller spacecraft such as CubeSat satellites, a salt-based monopropellant is showing promise. It can be used both in high-thrust chemical propulsion for fast time-sensitive maneuvers, and electric mode for slow maneuvers, such as orbit maintenance. Now, researchers in the Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign have more knowledge about how it performs under pressure to inform rocket design.

Pressure-induced 2D-3D conversion in hybrid lead iodide layered perovskite
Here, we demonstrate that 2D D-J perovskites experience various transitions under pressure, such as crystalline-amorphous and 2D-three-dimensional structural transformation, and the probable metallization are strongly suggested. Moreover, the fundamental changes in the material properties are observed at ambient conditions after pressure treatment, which is crucial for achieving the desired characteristics for viable applications.

People who feel dizzy when they stand up may have higher risk of dementia
Some people who feel dizzy or lightheaded when they stand up may have an increased risk of developing dementia years later, according to a new study published in the August 12, 2020, online issue of Neurology, the medical journal of the American Academy of Neurology. The condition, called orthostatic hypotension, occurs when people experience a sudden drop in blood pressure when they stand up. (2020-08-06)

Researchers discover predictor of laser treatment success in patients with glaucoma
More than 70 million people worldwide suffer from glaucoma. Treatment options have traditionally included eye drops to reduce the fluid the eye produces or surgery to unclog the eye's drainage. But a new study from the University of Missouri School of Medicine and MU Health Care provides insight into which patients might benefit most from a noninvasive treatment called selective laser trabeculoplasty (SLT), which relieves pressure by using a laser to alter the eye tissue, resulting in better fluid drainage.

Wealthier men are more likely to develop high blood pressure
Working men with higher incomes are more likely to develop high blood pressure, reports a study presented at the 84th Annual Scientific Meeting of the Japanese Circulation Society (JCS 2020). ''Men with higher incomes need to improve their lifestyles to prevent high blood pressure,'' said study author Dr. Shingo Yanagiya of the Hokkaido University Graduate School of Medicine, Sapporo, Japan.

Antiviral method against herpes paves the way for combatting incurable viral infections
Researchers at Lund University in Sweden have discovered a new method to treat human herpes viruses. The new broad-spectrum method targets physical properties in the genome of the virus rather than viral proteins, which have previously been targeted. The treatment consists of new molecules that penetrate the protein shell of the virus and prevent genes from leaving the virus to infect the cell. It does not lead to resistance and acts independently of mutations in the genome of the virus. (2020-07-24)

Regular exercise helps prevent high blood pressure, even in areas of high air pollution
Regular physical activity is a healthy way to prevent and reduce high blood pressure, even in places where pollution levels are relatively high. Air pollution increases high blood pressure risk, yet it does not outweigh the benefits of physical activity on high blood pressure prevention. Addressing air pollution remains important for high blood pressure prevention. (2020-07-20)

Pressure suppresses carrier trapping in 2D halide perovskite
Here, we show a remarkable PL enhancement by 12 folds using pressure to modulate the structure of a recently developed 2D perovskite (HA)2(GA)Pb2I7 (HA = n?hexylammonium, GA = guanidinium). This structure features an extremely large cage previously unattainable, affording us a rare opportunity to understand the structure?property relationship and explore emergent phenomena in halide perovskites.

The explanation announced by the two teams is attracting much attention from related academic and industrial circles. (2020-07-13)

When calling loudly, echolocation is costly for small bats
Calling in the ultrasonic range enables small bats to orient themselves in the dark and track down insects. Louder calls travel farther, improving a bat's ability to detect their prey. It was long assumed that echolocation does not contribute much to energy expenditure in flight because individuals couple their calls with the beat of their wings. Scientists at the Leibniz-IZW in Berlin have now shown that high intensity echolocation calls substantially contribute to energy expenditure. (2020-07-13)

Transgenic rice lowers blood pressure of hypertensive rats
In the future, taking your blood pressure medication could be as simple as eating a spoonful of rice. This 'treatment' could also have fewer side effects than current blood pressure medicines. As a first step, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have made transgenic rice that contains several anti-hypertensive peptides. When given to hypertensive rats, the rice lowered their blood pressure. (2020-06-24)

Wounded plants: How they coordinate their healing
When we cut our fingers, blood rushes out of the wound to close it. However, the vegetable, we just wanted to slice and dice, would have reacted utterly different to this injury. Scientists at the Institute of Science and Technology Austria (IST Austria) investigated how plant cells heal wounds. In their results, published in PNAS on June 15, the researchers discovered that the hormone Auxin and pressure changes are crucial to regeneration. (2020-06-15)

Transient increase in blood pressure promotes some blood vessel growth
Blood vessels are the body's transportation system, carrying oxygen and nutrients to cells and whisking away waste. A research team led by a scientist at Tokyo University of Agriculture and Technology (TUAT) in Japan has discovered a mechanism by which the growth of these vessels' inner liner is stimulated, which may lead to therapeutics that could cut vessels off from tumors or help rebuild vessels in degenerative diseases. (2020-06-12)

Overactive enzyme causes hereditary hypertension
After more than 40 years, several teams at the MDC and ECRC have now made a breakthrough discovery with the help of two animal models: they have proven that an altered gene encoding the enzyme PDE3A causes an inherited form of high blood pressure. This could lead to new concepts for the treatment of hypertension. (2020-06-11)

Biohybrid model uses organic lungs, synthetic muscles to re-create respiration mechanics
Discussed in APL Bioengineering, researchers created a high-fidelity respiratory simulator that accurately represents the interplay between the abdomen, diaphragm, lungs and pleural space, the fluid-filled membrane surrounding the thorax and lungs. The model, using swine lungs, soft robotic materials and artificial muscles, allows precise tuning of pressure in each part of the system, so specific disease conditions can be tested. It also proved extremely useful for testing ventilator-only respiration by removing the elastomeric diaphragm. (2020-06-09)
