Researchers begin to unravel the mysteries of kombucha fermentation

Science Daily - 14/07/2021
Scientists are beginning to unravel the key microorganisms that contribute to the fermentation of kombucha, research that is already aiding large-scale kombucha producers in the fast-growing industry.

Study shows Cannabis terpenes provide pain relief, contribute to 'entourage effect'

Science Daily - 14/07/2021
Researchers have found that terpenes mimic cannabinoids and produce similar pain-relieving effects, which are amplified when the two are used together.

Compound derived from turmeric essential oil has neuroprotective properties

Science Daily - 14/07/2021
Researchers have found that a component derived from turmeric essential oil, ar-turmerone, and its derivatives act directly on dopaminergic neurons to exert a neuroprotective effect on tissue cultures of a Parkinson's disease model. The effect appears to be due to the enhancement of cellular antioxidant potency through Nrf2 activation. The researchers believe that the ar-turmerone derivatives identified in this study can be utilized as new therapeutic agents for Parkinson's disease.

Tamarind shells converted into an energy source for vehicles

Science Daily - 14/07/2021
A team of scientists has found a way to process tamarind shells which are rich in carbon, converting the waste material into carbon nanosheets, which are a key component of supercapacitors - energy storage devices that are used in automobiles, buses, electric vehicles, trains, and elevators.

Hard to swallow: Coral cells seen engulfing algae

Science Daily - 14/07/2021
Scientists have seen stony coral cells engulf dinoflagellates - single-celled, photosynthetic algae that are crucial for keeping coral alive. The researchers cultured endoderm-like cells from the stony coral, Acropora tenuis. Around 40% of coral cells incorporated the algae in around 30 minutes and remained healthy for one month. The research is a step towards understanding the partnership between coral and dinoflagellates and could shed light on how coral bleaching occurs.

Methamphetamine use drove surge in heart failure hospitalizations, costs in California

Science Daily - 14/07/2021
Methamphetamine-related heart failure hospitalizations rose a staggering 585% between 2008 and 2018 in California. Costs associated with methamphetamine-related hospitalizations in California jumped even higher, 840%.

Like priming a pump, cells damaged by chronic lung disease can result in severe COVID

Science Daily - 14/07/2021
New research suggests that the airway cells of patients with chronic lung diseases are 'primed' for infection by the COVID-19 virus, resulting in more severe symptoms, poorer outcomes and a greater likelihood of death.

Rapid evolution in waterfleas yields new conservation insights

Science Daily - 14/07/2021
The extraordinary ability of animals to rapidly evolve in response to predators has been demonstrated via genetic sequencing of a waterflea population across nearly two decades.

Drug combination shows meaningful responses for malignant peritoneal mesothelioma patient

Science Daily - 14/07/2021
A phase II study found that treatment with atezolizumab and bevacizumab was well-tolerated and resulted in a 40% objective response rate in patients with advanced malignant peritoneal mesothelioma, a rare cancer in the lining of the abdomen.

Vaccine hesitancy in young adults may hamper herd immunity

Science Daily - 14/07/2021
Vaccine skepticism among young adults may stall efforts to achieve herd immunity -- a threshold in which approximately 80 percent of a population is vaccinated against the coronavirus.

New study links moderate alcohol use with higher cancer risk

Science Daily - 14/07/2021
A new study has found an association between alcohol and a substantially higher risk of several forms of cancer, including breast, colon, and oral cancers. Increased risk was evident even among light to moderate drinkers (up to two drinks a day), who represented 1 in 7 of all new cancers in 2020 and more than 100,000 cases worldwide.

New system for tracking macaws emphasizes species' conservation needs

Science Daily - 14/07/2021
New data on macaw movements has the potential to greatly improve conservation strategies for the scarlet macaw, as well as similar species of large parrots.

Liquid metal sensors and AI could help prosthetic hands to 'feel'

Science Daily - 14/07/2021
Prosthetics currently lack the sensation of 'touch.' To enable a more natural feeling prosthetic hand interface, researchers are the first to incorporate stretchable tactile sensors using liquid metal and machine learning. This hierarchical multi-finger tactile sensation integration could provide a higher level of intelligence for artificial hands by improving control, providing haptic feedback and reconnecting amputees to a previously severed sense of touch.

Solar radio signals could be used to monitor melting ice sheets

Science Daily - 14/07/2021
A new method for seeing through ice sheets using radio signals from the sun could enable cheap, low-power and widespread monitoring of ice sheet evolution and contribution to sea-level rise.

Banishing bandits: Other countries bear the cost

Science Daily - 14/07/2021
There are proven strategies to stop bandits from illegally fishing in Australian waters -- but it currently comes at a cost to the Pacific region's poorer countries.

Study shows benefits of early anticlotting therapy in moderate COVID-19

Science Daily - 14/07/2021
New research shows that administering a full dose of a standard blood thinner early to moderately ill hospitalized patients with COVID-19 could halt the thrombo-inflammation process and reduce the risk of severe disease and death.

Study evaluates biodiversity impacts of alternative energy strategies

Science Daily - 14/07/2021
Climate change mitigation efforts have led to shifts from fossil-fuel dependence to large-scale renewable energy. However, renewable energy sources require significant land and could come at a cost to ecosystems. A new study evaluates potential conflicts between alternative energy strategies and biodiversity conservation.

Impairments found in neurons derived from people with schizophrenia and genetic mutation

Science Daily - 14/07/2021
A scientific team has shown that the release of neurotransmitters in the brain is impaired in patients with schizophrenia who have a rare, single-gene mutation known to predispose people to a range of neurodevelopmental disorders.

Eating whole grains linked to smaller increases in waist size, blood pressure, blood sugar

Science Daily - 14/07/2021
A study finds middle- to older-aged adults who ate more servings of whole grains, compared to those who ate fewer, were more likely to have smaller increases in waist size, blood pressure, and blood sugar levels as they aged. All three are linked with increased risk of heart disease.

Bacteria are key to vaginal health, study finds

Science Daily - 14/07/2021
A recent study defines a mechanistic role for an understudied bacteria family in gynecologic disease.
