New fluorescence-based assay offers hope in fighting antibiotic resistance

New fluorescence-based assay offers hope in fighting antibiotic resistance

A team of researchers has come up with a fluorogenic probe that can detect the activity of multidrug-resistant pathogens in an assay system.

Carbapenems are among the "antibiotics of last resort" and can fight infections for which other drugs have long lost their effectiveness. However, even carbapenem-resistant pathogenic strains have emerged over the last decades. To find out whether a pathogen contains carbapenem-cleaving enzymes, the carbapenemases, Chinese scientists have developed a simple and fast assay based on a fluorescent probe and optical detection.

Virus hydrophobicity can help purify vaccines

Virus hydrophobicity can help purify vaccines

A team of researchers has found that hydrophobic proteins on virus surfaces can help purify vaccines.

The complex structures making the surface of a virus are small weaves of proteins that make a big impact on how a virus interacts with cells and its environment.

A slight change in protein sequence makes this surface slightly water-repelling, or hydrophobic, causing it to stick to other hydrophobic surfaces. A new paper, published recently in Colloids and Surfaces B: Biointerfaces, details surface hydrophobicity in porcine parovirus (PPV).

Survivors of childhood brain tumours have more fat

Survivors of childhood brain tumours have more fat

A team of researchers has shed light on why survivors of childhood brain tumours may be prone to heart disease, stroke, type 2 diabetes and early death.

The McMaster University researchers discovered that while survivors of childhood brain tumours have a similar Body Mass Index (BMI) to healthy children with no cancer, they have more fat tissue overall, and especially around the abdomen.

Experiencing Aurora Australis 'alters' passengers' lives!

Experiencing Aurora Australis 'alters' passengers' lives!

Following a huge explosion of magnetic field and plasma from the Sun's corona, Tasmania's skyline has been aglow in recent days - with vivid purple and green lights illuminating the horizon.

A few passengers, aboard the first commercial flight to witness the Aurora Australis, landed in New Zealand and the 130 star-struck passengers have taken to social media to share their experience.

The duration of the flight was eight-hours and it took off from the South Island on Thursday, flying to a latitude of 62 degrees south to view of the aurora.

Rejoice beer lovers! A pint a day keeps heart problems at bay

Drinking a pint of ordinary beer, lager or two small pub measure (25 ml) of spirits a day may lower the risk of several, but not all, cardiovascular diseases, suggests a study.

The study appeared in the journal of BMJ.

According to researchers moderate drinking is associated with a lower risk of several, but not all, cardiovascular diseases compared with abstinence or heavy drinking.

Moderate drinking is defined as no more than 14 units (112 grams) of alcohol a week.

Weight training, jogging promotes bone growth in men

Weight training, walking, hiking, jogging for 12 months may increase the particular hormone associated with bone growth, promoting bone formation, increasing bone density.

According to researchers from the University of Missouri-Columbia in the US, long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, in men and increase IGF-1, a hormone associated with bone growth an and prevent osteoporosis.

The study was published in the journal of Bone.

World Tuberculosis Day: Rising need to increase awareness among kids

Ranking above HIV and malaria, health experts on the occasion of World Tuberculosis day, called for an increase in public awareness on the rising cases of TB among children.

Challenges in diagnosis and delayed treatment results in two to seven percent rise in TB cases among children in India

Six countries account for 60 percent of the total TB deaths, with India leading the count, followed by Indonesia, China, Nigeria, Pakistan and South Africa.

World Tuberculosis Day 2017 - Unite to End TB: Leave No One Behind

Tuberculosis is one of the top 10 causes of death across the globe, ranking above HIV and malaria. According to the World Health Organization (WHO), in 2015, there were 10.4 million new cases of TB worldwide.

Six countries account for 60% of the total TB deaths, with India leading the count, followed by Indonesia, China, Nigeria, Pakistan and South Africa. As per WHO, each year about 2.2 million people develop TB in India and an estimated 220,000 die from the disease.

Did you know? Blind have enhanced hearing, smell, cognitive functions

A study finds that people who are born blind have heightened sense of hearing, smell and touch, suggesting that their brain "rewires" itself in the absence of visual information to boost other senses.

According to Massachusetts Eye and Ear researchers, the brains of those, who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions.

A new species of terrestrial crab found in Hong Kong

A new species of terrestrial crab found in Hong Kong

What the CRAB!

The scientists have found a new species of terrestrial crab, climbing trees on the eastern coast of Hong Kong.

The species is described in the open access journal ZooKeys.

All specimens spotted during the survey have been collected at a height of approximately 1.5 - 1.8 m, walking on the bark of the branches at ebbing and low tides.

The characteristics of the newly found species are squarish predominantly dark brown carapace, very long legs and orange chelipeds.
