Enzyme With A Light-Activated Catalyst Offers For Synthesis

The coupling of an enzyme with a light-activated catalyst offers great potential for organic synthesis. Catalysts working in pairs can promote more-effective reactions than can the same catalysts used sequentially. The study was published in the journal Nature.

The development of catalytic reactions is a dominant theme in chemistry, especially in industry, where major efforts are underway to develop large-scale chemical processes that are sustainable and avoid producing unnecessary waste. Chemical reactions can be accelerated using many types of catalyst, including metals (or their salts or complexes), small organic molecules, enzymes and light-activated catalysts.

Atoms Aid In Combatting Diseases Are Visualized By Microscope

Researchers showed that the battle against disease as it uses visualization as an enabler for scientific discovery. The molecular details it reveals are so precise, it allows the mapping of the entire surface of biological molecules such as proteins and DNA.

Considered as the most advanced and powerful microscope of Australia because of its capability to visualize down to the level of individual atoms, the Titan Krios will begin its working life as part of a suite of transformative technology.

The University of Wollongong’s (UOW) three-meter tall, one-tonne FEI Thermo Fisher Titan Krios cryo-electron microscope allows scientists to see the inner workings of human cells with unprecedented clarity.

Music Intervention As A Tool in Improving Patient Experience in Palliative Care

Hospice and palliative care patients who listen to live music in their rooms as part of their treatment feel better both emotionally and physically, and request fewer opioid-based medications, a new study found. Doctors working with seriously ill patients offered them the option to have a flutist play music in their rooms as part of their palliative care, which focuses on improving quality of life and relieving symptoms for patients with serious illnesses.

Manipulation During Rhythmic Arm Movements in Microgravity

Predicting the consequences of one’s own movements can be challenging when confronted with completely novel environmental dynamics, such as microgravity in space. The absence of gravitational force disrupts internal models of the central nervous system (CNS) that have been tuned to the dynamics of a constant 1-environment since birth.

In the context of object manipulation, inadequate internal models produce prediction uncertainty evidenced by increases in the grip force (GF) safety margin that ensures a stable grip during unpredicted load perturbations. This margin decreases with practice in a novel environment. However, it is not clear how the CNS might react to a reduced, but non-zero, gravitational field, and if adaptation to reduced gravity might be beneficial for subsequent microgravity exposure.

Ear Infection Making Your Child Cry?

Ear infections are one of the most common infections among infants. While there are different ear infections, otitis media is the most common. Statistics show that most kids will contract an infection at least once before they turn 2 years old.

Causes and Symptoms of Ear Infections

The ear has three parts: outer, middle (behind the eardrum) and inner (regulates hearing and balance). The two types of ear infections are swimmer’s ear, which affects the outer ear, and otitis media, an inflammation of the middle ear.

Obese Patients With PTSD Leads To Increased Risk Of Diabetes

Research finds post-traumatic stress disorder does not directly lead to type 2 diabetes mellitus (T2DM), instead, obesity in PTSD patients accounts for the increased risk. The study, "The Role of Obesity in the Association Between Posttraumatic Stress Disorder and Incident Diabetes" was published in JAMA Psychiatry.

Post-traumatic stress disorder is associated with risk factors for type 2 diabetes, including poor diet, lack of exercise, alcohol abuse and obesity. The risk factors may interact with hypothalamic-pituitary-adrenal changes to increase the risk of type 2 diabetes.
