Three decades of data in Bangladesh show elevated risk of infant mortality In flood-prone areas

Science Daily - 06/12/2023
A new study estimates 152,753 excess infant deaths were attributable to living in flood-prone areas in Bangladesh over the past 30 years. The findings begin to unspool the long term public health impacts of recurring environmental hazards such as flooding, wildfires, or extreme heat, many of which are becoming more common or more severe under climate change.

Older organs accelerate aging in transplant recipients

Science Daily - 06/12/2023
A study found that in preclinical models, transplanting older organs can trigger senescence in younger recipients. They observed that young and middle-aged mice that received heart transplants from older mice had impaired physical capacity, with reduced running times and grip strengths. Middle-aged mice who received older hearts also showed increased anxiety-related behavior, impaired memory and poorer learning performances.

Giant rabies study with 50,000 dogs says only vaccines can stop disease

The Hindu:Science - 05/12/2023
Reducing dog numbers by killing them is ethically wrong and now reported to be scientifically ineffective.

Harvesting water from air with solar power

Science Daily - 05/12/2023
Researchers have developed a promising new solar-powered atmospheric water harvesting technology that could help provide enough drinking water for people to survive in difficult, dryland areas: They synthesized a super hygroscopic gel capable of absorbing and retaining an unparalleled amount of water. One kilogram of dry gel could adsorb 1.18 kilograms of water in arid atmospheric environments and up to 6.4 kilograms in humid atmospheric environments. This hygroscopic gel was simple and inexpensive to prepare and would consequently be suitable for large-scale preparation.

Using AI to find microplastics

Science Daily - 05/12/2023
An interdisciplinary research team is using artificial intelligence (AI) to identify microplastics faster and more accurately than ever before.

'Shocking' discovery: Electricity from electric eels may transfer genetic material to nearby animals

Science Daily - 05/12/2023
Researchers have discovered that electric eels can alter the genes of tiny fish larvae with their electric shock. Their findings help to better understand electroporation, a method by which genes can be transported using electricity.

Breakthrough in photoactivatable nanomedicine for the treatment of age-related macular degeneration

Science Daily - 05/12/2023
Researchers have developed a light-activatable prodrug nanomedicine for age-related macular degeneration (AMD) therapy. Through the intravenous injection of the nanomedicine and application of light irradiation to diseased eyes, anti-angiogenic and photodynamic combination therapy can be activated, offering a minimally invasive alternative for the treatment of AMD and other ocular disorders characterized by abnormal blood vessel growth.

Glial tone of aggression

Science Daily - 05/12/2023
While anger and aggression are instinctive behaviors found across many species, leaving these emotions unchecked can lead to conflict and violence. In a recent study, researchers demonstrated that neuronal-glial interactions in the cerebellum determine the degree of aggression exhibited by mice. This suggests that future therapeutic methods could adjust glial activity in the cerebellum to help reduce unwanted aggression.

Eye scans provide crucial insights into kidney health

Science Daily - 05/12/2023
3D eye scans can reveal vital clues about kidney health that could help to track the progression of disease, research suggests. The advance could revolutionize monitoring of kidney disease, which often progresses without symptoms in the early stages. Experts say the technology has potential to support early diagnosis as current screening tests cannot detect the condition until half of the kidney function has been lost.

Diamonds and rust help unveil 'impossible' quasi-particles

Science Daily - 05/12/2023
Researchers have discovered magnetic monopoles -- isolated magnetic charges -- in a material closely related to rust, a result that could be used to power greener and faster computing technologies.

Exposure to soft robots decreases human fears about working with them

Science Daily - 05/12/2023
Seeing robots made with soft, flexible parts in action appears to lower people's anxiety about working with them or even being replaced by them. A study found that watching videos of a soft robot working with a person at picking and placing tasks lowered the viewers' safety concerns and feelings of job insecurity. This was true even when the soft robot was shown working in close proximity to the person. This finding shows soft robots hold a potential psychological advantage over rigid robots made of metal or other hard materials.

Laser additive manufacturing: Listening for defects as they happen

Science Daily - 05/12/2023
Researchers have resolved a long-standing debate surrounding laser additive manufacturing processes with a pioneering approach to defect detection.

Reliable research and evidence-based recommendations scarce for women who exercise according to menstrual cycle

Science Daily - 05/12/2023
There is no shortage of advice for women on what to eat, how to train, or what supplements to take during their menstrual cycles, but a new review by an international team of scientists has found little evidence to support such recommendations. In fact, they found sparse research on women and exercise at all, and even less on the effect of their periods on sports performance, physiology, or physical fitness.

Unlocking neutron star rotation anomalies: Insights from quantum simulation

Science Daily - 05/12/2023
A collaboration between quantum physicists and astrophysicists has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research establishes a strong link between quantum mechanics and astrophysics and paves the way for quantum simulation of stellar objects from Earth.

Astronomers determine the age of three mysterious baby stars at the heart of the Milky Way

Science Daily - 05/12/2023
Through analysis of high-resolution data from a ten-meter telescope in Hawaii, researchers have succeeded in generating new knowledge about three stars at the very heart of the Milky Way. The stars proved to be unusually young with a puzzling chemical composition that surprised the researchers.

New research shows how important protein keeps our cell membranes in balance

Science Daily - 05/12/2023
New research shows how important protein keeps our cell membranes in balance. Researchers have studied the structure, function and mechanisms of the protein ATP8B1, which flips lipid molecules in our cell membranes and plays a key role in bile biosynthesis. Importantly, ATP8B1 has also emerged as a genetic marker of Alzheimer's resilience. These results give new possibilities for therapeutic interventions in conditions related to bile homeostasis disorders and neurodegenerative diseases.
