New, holistic way to teach synthetic biology

Science Daily - 28/06/2024
Synthetic biology combines principles from science, engineering and social science, creating emerging technologies such as alternative meats and mRNA vaccines; Deconstructing synthetic biology across scales gives rise to new approach to uniting traditional disciplines; Case studies offer a modular, accessible approach to teaching at different institutions.

Why the harsh Snowball Earth kick-started our earliest multicellular ancestors

Science Daily - 28/06/2024
Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.

Cardiovascular health could be biggest risk factor for future dementia rates

Science Daily - 28/06/2024
Dementia risk factors associated with cardiovascular health may have increased over time compared to factors such as smoking and having less education, finds a new study.

Early childhood problems linked to persistent school absenteeism

Science Daily - 28/06/2024
Children who are not considered 'school ready' by their teachers are more than twice as likely to become persistently absent at some point in their education, according to a new study.

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems

Science Daily - 28/06/2024
Older coastal cities, like Philadelphia, New York and Boston are at risk of being inundated by untreated sewage during floods. Due in part to the design of their combined sewer systems and in part due to sea level rise, these cities could be facing a growing public health crisis as climate change also drives more extreme precipitation. The group recently published research that modeled the potential extent of the problem in a section of the coastal city of Camden, New Jersey, and the effectiveness of one proposed intervention to help protect these communities.

Sci-Five | The Hindu Science Quiz: On the world’s smallest cat

The Hindu:Science - 27/06/2024
This week’s Sci-five quiz is on the Rusty-spotted cat, the world’s smallest cat.

Should we ditch BMI and use the ‘body roundness index’ instead?

The Hindu:Science - 27/06/2024
BMI was never created for use in health and was developed using data from European people in the 19th century

‘Multi-omics’ is changing how India spots and treats TB, cancers

The Hindu:Science - 27/06/2024
Disease-specific consortia have sprung up around the country to create datasets for personalised medicine

Review of pathogenesis, research and treatment of amyloidosis

Science Daily - 27/06/2024
AL (immunoglobulin light chain) amyloidosis is a rare disease that often results in progressive organ dysfunction, organ failure and eventual death. Clonal plasma cells in the bone marrow secrete free light chains into circulation. These light chains are part of immunoglobulins, also called antibodies. But in this disease, light chains misfold and aggregate into amyloid fibrils that deposit in organs and tissues.

Tai Chi reduces risk of inflammatory disease, treats insomnia among breast cancer survivors

Science Daily - 27/06/2024
New research confirms that both Tai Chi and cognitive behavioral therapy can reduce insomnia in breast cancer survivors but also may provide additional health benefits by reducing inflammation and bolstering anti-viral defenses.

Do people who exercise more have a lower risk of ALS?

Science Daily - 27/06/2024
Moderate levels of physical activity and fitness may be linked to a reduced risk of amyotrophic lateral sclerosis (ALS) later in life, according to a new study. The study only found an association between physical activity and risk of ALS in male participants, not female participants.

Could preventative drug be effective in people with migraine and rebound headache?

Science Daily - 27/06/2024
A drug used to prevent migraine may also be effective in people with migraine who experience rebound headaches, according to a new study.

Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds

Science Daily - 27/06/2024
We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.

Simple new process stores CO2 in concrete without compromising strength

Science Daily - 27/06/2024
By using carbonated -- rather than still -- water during the concrete manufacturing process, a team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction material.

Understanding quantum states: New research shows importance of precise topography in solid neon qubits

Science Daily - 27/06/2024
A new study shows new insight into the quantum state that describes the condition of electrons on an electron-on-solid-neon quantum bit, information that can help engineers build this innovative technology.

Study shows how liver damage from stress and aging might be reversible

Science Daily - 27/06/2024
While the liver is one of the body's most resilient organs, it is still vulnerable to the ravages of stress and aging, leading to disease, severe scarring and failure. A research team now might have found a way to turn back time and restore the liver. In experiments using mice and liver tissue from humans, the researchers identified how the aging process prompts certain liver cells to die off. They were then able to reverse the process in the animals with an investigational drug.

Public perception of scientists' credibility slips

Science Daily - 27/06/2024
New analyses find that public perceptions of scientists' credibility -- measured as their competence, trustworthiness, and the extent to which they are perceived to share an individual's values -- remain high, but their perceived competence and trustworthiness eroded somewhat between 2023 and 2024. The research also found that public perceptions of scientists working in artificial intelligence (AI) differ from those of scientists as a whole.

South African scientists make rhino horns radioactive to curb poaching

The Hindu:Science - 27/06/2024
The radioactive material would render the horn useless for human consumption while setting off alarms at border posts
