Two years ago, a group of infants died at the university hospital and it was found to be Gram-negative bacteria that caused their death. The Gram-negative bacteria turn into pink color and Gram-positive bacteria turn into violet color when stained using the Gram stain which is a bacterial staining method used since 1884. Usually, bacteria that cause tetanus, pneumonia, and food poisoning are types of Gram-positive bacteria.

Sometimes a little gentle peer persuasion goes a long way toward correcting a large problem.

That's the message from researchers at Johns Hopkins Medicine and seven collaborating health care organizations which report that a "Dear Colleague" performance evaluation letter successively convinced physicians nationwide to reduce the amount of tissue they removed in a common surgical treatment for skin cancer to meet a professionally recognized benchmark of good practice.

Climate change has raised the risk of a fungal disease that ravages banana crops, new research shows.

Black Sigatoka disease emerged from Asia in the late 20th Century and has recently completed its invasion of banana-growing areas in Latin America and the Caribbean.

The new study, by the University of Exeter, says changes to moisture and temperature conditions have increased the risk of Black Sigatoka by more than 44% in these areas since the 1960s.

Cooperation within a group of people is key to many successful endeavors, including scientific ones. According to a study published in Nature Communications, cooperation among competing fishers can boost fish stocks on coral reefs.

The study analyzed the social relationships among competing fisheries, the species they collect, and the local reefs from which these species are extracted.

Venice, Italy - 3 May 2019: Training for and completing a first-time marathon "reverses" ageing of major blood vessels, according to research presented today at EuroCMR 2019, a scientific congress of the European Society of Cardiology (ESC).1 The study found that older and slower runners benefit the most.

NASA's Aqua satellite focused an infrared eye on a very powerful Tropical Cyclone Fani as it approached landfall in northeastern India. Fani is a powerful Category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale.

A new study shows that vaccination may reduce the impact of white-nose syndrome in bats, marking a milestone in the international fight against one of the most destructive wildlife diseases in modern times.

Reconstruction of the most complete fossil lizard found in Australia, a 15 million year old relative of our modern blue tongues and social skinks named Egernia gillespieae, reveals the creature was equipped with a robust crushing jaw and was remarkably similar to modern lizards.

A new study lead by Flinders University PHD student Kailah Thorn, published in the journal of Vertebrate Palaeontology, combined the anatomy of of living fossils with DNA data to put a time scale on the family tree of Australia's 'social skinks'.

Scientists have discovered a new method for quickly and efficiently mapping the vast network of connections among neurons in the brain.

Researchers combined infrared laser stimulation techniques with functional magnetic resonance imaging in animals to generate mapping of connections throughout the brain. The technique was described in a study published in the journal Science Advances.

Programming children watch on American TV shows systematic gender inequality, according to new research co-authored by Dafna Lemish of the School of Communication and Information at Rutgers University-New Brunswick.

When spies meet, they use secret handshakes to confirm their identities, ensuring they are who they say they are. Now, researchers at Stevens Institute of Technology, and colleagues, have solved a 15-year-old problem that allows handshake-style encryption to be used for time-delayed digital communications such as email - a challenge once thought to be impossible.

ISTANBUL, TURKEY - In a paper published in the Journal of Biological Chemistry, Dr. Özdemir has studied two protein families named Rho GTPases and IQGAPs, which are known to play an important role in cancer metastasis. These two "suspicious" protein families have been studied by many researchers over the years, but the interaction between them had not previously been fully understood.

In 1956, the Würzburg botanist Otto Ludwig Lange observed an unusual phenomenon in the Mauritanian desert in West Africa: he found plants whose leaves could heat up to 56 degrees Celsius. It is astonishing that leaves can withstand such heat. At the time, the professor was unable to say which mechanisms were responsible for preventing the leaves from drying out at these temperatures. More than 50 years later, the botanists Markus Riederer and Amauri Bueno from Julius-Maximilians-Universität Würzburg (JMU) in Bavaria, Germany, succeeded in revealing the secret.

Biodegradable plastic bags are still capable of carrying full loads of shopping after being exposed in the natural environment for three years, a new study shows.

Researchers from the University of Plymouth examined the degradation of five plastic bag materials widely available from high street retailers in the UK.

They were then left exposed to air, soil and sea, environments which they could potentially encounter if discarded as litter.

Obesity is linked with an increased risk of developing anxiety and depression in children and adolescents, independent of traditional risk factors such as parental psychiatric illness and socioeconomic status, according to new research being presented at this year's European Congress on Obesity (ECO) in Glasgow, UK (28 April-1 May).
