Scientists find that microRNA affects inflammation in lupus disease

Science Daily - 26/01/2023
Scientists have discovered the role of microRNA on inflammation in lupus disease. They identified the microRNAs that are downregulated in the disease and how they converge to cause the disease.

Versatile robo-dog runs through the sandy beach at 3 meters per second

Science Daily - 26/01/2023
Meet the new addition to the robo-dog family, 'RaiBo', that can run along the sandy beach without losing balance and walk through grassy fields and back on the hard-floored tracking fields all on its own -- no further tinkering necessary.

Physicists solve mystery of two-dimensional quasicrystal formation from metal oxides

Science Daily - 26/01/2023
The structure of two-dimensional titanium oxide brakes-up at high temperatures by adding barium; instead of regular hexagons, rings of four, seven and ten atoms are created that order aperiodically. A team has now solved the riddle of two-dimensional quasicrystal formation from metal oxides.

New spray fights infections and antibiotic resistance

Science Daily - 26/01/2023
The World Health Organization (WHO) ranks antibiotic resistance as one of the top ten threats to global health. There is therefore a great need for new solutions to tackle resistant bacteria and reduce the use of antibiotics. A group of researchers are now presenting a new spray that can kill even antibiotic-resistant bacteria, and that can be used for wound care and directly on implants and other medical devices.

Why episodes of low blood sugar worsen eye disease in people with diabetes

Science Daily - 26/01/2023
People with diabetes who experience periods of low blood sugar -- a common occurrence in those new to blood sugar management -- are more likely to have worsening diabetic eye disease. Now, researchers say they have linked such low blood sugar levels with a molecular pathway that is turned on in oxygen-starved cells in the eye.

Scientific study on sea erosion begins at Kozhikode's Kappad

The Hindu:Science - 26/01/2023
Kappad is the only beach in Kerala to get the International Blue Flag certificate, an award given to beaches that meet strict guidelines on ensuring eco-friendly measures, safety, and hygiene

Ultrasonic sensors can safeguard residential gas lines

Science Daily - 25/01/2023
A team researchers is investigating a new method to monitor underground gas pipelines with high-tech sensors that can make it easier to find weaknesses, discrepancies and even a diversion in residential natural gas lines.

Transistors repurposed as microchip 'clock' address supply chain weakness

Science Daily - 25/01/2023
A new technique uses standard chip fab methods to fabricate the building block of a timing device, critical to all microprocessors. Currently, this timing device, known as an acoustic resonator, must be produced separately, often overseas, creating a supply chain and security weakness. The technique would allow for this timing device to be integrated with the microprocessor using standard CMOS processing, rather than later bunded with the microprocessor.

New shield blocks electromagnetic interference while allowing wireless optical signals

Science Daily - 25/01/2023
Researchers have demonstrated for the first time a mechanically flexible silver mesh that is visibly transparent, allows high-quality infrared wireless optical communication and efficiently shields electromagnetic interference in the X band portion of the microwave radio region.

Body phenotypes say a lot, but not everything, about a person's health

Science Daily - 25/01/2023
Researchers studying body phenotypes -- the observable characteristics like height, behavior, appearance and more measurables -- found that regardless of the muscle they had, high levels of fat mass in an individual were associated with poorer overall health.

Watch this person-shaped robot liquify and escape jail, all with the power of magnets

Science Daily - 25/01/2023
Inspired by sea cucumbers, engineers have designed miniature robots that rapidly and reversibly shift between liquid and solid states. On top of being able to shape-shift, the robots are magnetic and can conduct electricity. The researchers put the robots through an obstacle course of mobility and shape-morphing tests.

Supplementation with amino acid serine eases neuropathy in diabetic mice

Science Daily - 25/01/2023
The study adds to growing evidence that some often-underappreciated, 'non-essential' amino acids play important roles in the nervous system. The findings may provide a new way to identify people at high risk for peripheral neuropathy, as well as a potential treatment option.

Wearable sensor uses ultrasound to provide cardiac imaging on the go

Science Daily - 25/01/2023
Engineers and physicians have developed a wearable ultrasound device that can assess both the structure and function of the human heart. The portable device, which is roughly the size of a postage stamp, can be worn for up to 24 hours and works even during strenuous exercise.

New geosciences study shows Triassic fossils that reveal origins of living amphibians

Science Daily - 25/01/2023
A team of paleontologists have discovered the first 'unmistakable' Triassic-era caecilian fossil -- the oldest-known caecilian fossils -- thus extending the record of this small, burrowing mammal by roughly 35 million years. The find also fills a gap of at least 87 million years in the known historical fossil record of the amphibian-like creature.

Expert analysis refutes claims that humans are colonized by bacteria before birth

Science Daily - 25/01/2023
Scientific claims that babies harbor live bacteria while still in the womb are inaccurate, and may have impeded research progress, according to new research/

Scientists discover the evolutionary secret behind different animal life cycles

Science Daily - 25/01/2023
Researchers uncover for the first time the mechanism that likely explains how embryos form either a larva or a miniature version of the adult.

Risk of developing heart failure much higher in rural areas vs. urban

Science Daily - 25/01/2023
Adults living in rural areas of the United States have a 19% higher risk of developing heart failure compared to their urban counterparts, and Black men living in rural areas have an especially higher risk -- 34%, according to a large observational study.

Special vascular cells adjust blood flow in brain capillaries based on local energy needs

Science Daily - 25/01/2023
Researchers have discovered that a certain type of cell that sits on top of the brain's smallest blood vessels senses when their brain region needs energy. When glucose levels are low, these cells signal blood vessels to dilate, increasing the blood flow regionally and allowing more energy to fuel that part of the brain.

What crocodile DNA reveals about the Ice Age

Science Daily - 25/01/2023
What drives crocodile evolution? Is climate a major factor or changes in sea levels? Determined to find answers to these questions, researchers discovered that while changing temperatures and rainfall had little impact on the crocodiles' gene flow over the past three million years, changes to sea levels during the Ice Age had a different effect.
