In the version of evolutionary theory most of us are familiar with, randomly occurring variation in traits, caused by mutations in our DNA, can be fixed in a population through natural selection. However, writing in Epigenetics journal, a team of Swedish researchers from Linköping University suggests that mutations that can be caused by environmental changes, not just random chance, might be responsible for species diversity.

Until quite recently, it was assumed that DNA mutations causing new gene variations occurred more or less randomly. While random mutations do occur, recent research has shown that genes can be altered by environmental influences too. According to a study published in Epigenetics journal, a particular type of mutation, linked to epigenetic changes, has, over time, led to new animal breeds—and could be responsible for whole new species.

The amazing properties and unique flavor of turmeric have been valued and used for centuries. This incredibly healthy deep-yellow spice offers a myriad of medicinal qualities, and is commonly used in the Chinese, Indian and Ayurvedic medicine. health, medicine, science, health, medicine, science, health, medicine, science, health, science.

People have used turmeric in the treatment of wounds and cuts, skin issues, muscle sprains, liver diseases, respiratory issues, and gastric issues, as well as digestive problems, inflammations, infections, and malignant tumors.

Its active ingredient, curcumin, provides powerful antimicrobial, anti-inflammatory, and antioxidant properties. Turmeric effectively fights inflammation in the body, osteoarthritis, gastritis, microbes, gastric and peptic ulcers, improves the function of the brain and treats Alzheimer’s disease, and helps in the case of countless other health issues. health, medicine, science, health, medicine, science, health, medicine, science, health, science.

Researchers at Mayo Clinic have identified the enzyme, called CD38, that is responsible for the decrease in nicotinamide adenine dinucleotide (NAD) during aging, a process that is associated with age-related metabolic decline. Results demonstrated an increase in the presence of CD38 with aging in both mice and humans. The results appear today in Cell Metabolism.

“As we age, we experience a decline in our metabolism and metabolic function. This increases the incidence of age-related metabolic diseases like obesity, diabetes and others,” says Eduardo Chini, M.D., Ph.D., anesthesiologist and researcher for Mayo Clinic’s Robert and Arlene Kogod Center on Aging and lead author of the study. “Previous studies have shown that levels of NAD decline during the aging process in several organisms. This decrease in NAD appears to be, at least in part, responsible for age-related metabolic decline.”

In this study, researchers at the Center on Aging have shown that CD38, an enzyme that is present in inflammatory cells, is directly involved in the process that mediates the age-related NAD decline. Comparing 3- to 32-month-old mice, researchers found that levels of CD38 increased at least two to three times during chronological aging in all tissues tested, including the liver, fat, spleen and skeletal muscle.

Researchers at the Universities of Abuja and Nigeria, in collaboration with the University of Bristol, have detected a potentially human-infective microbe in pet dogs in Nigeria.

Dogs in tropical Africa run the risk of contracting canine trypanosomosis if they are bitten by bloodsucking tsetse flies carrying trypanosomes – microscopic, single-celled organisms found in the bloodstream. In dogs, this disease runs a severe course and is often fatal; “white eyes” or corneal cloudiness is one of the characteristic and obvious signs of the disease.

Sick dogs suspected of trypanosomosis are frequently brought to the University of Nigeria Veterinary Teaching Hospital (UNVTH) in Nsukka, where diagnosis relies on examination of a blood smear under the microscope. While trypanosomes are easily detected by their rapid motion among the blood cells, it is hard to determine the exact species of trypanosome by microscopy alone.

Pet cloning is illegal in many countries but approved in several states including South Korea and the US, where the singer Barbra Streisand announced last year she had cloned her dog. The first significant success in animal cloning was Dolly the sheep, born in Britain in 1996 as the first mammal cloned from an adult cell. In 2005, researchers in South Korea cloned the first dog.

In what could be a breakthrough for body sensor and navigation technologies, researchers at KTH have developed the smallest accelerometer yet reported, using the highly conductive nanomaterial, graphene.

Each passing day, nanotechnology and the potential for graphene material make new progress. The latest step forward is a tiny accelerometer made with graphene by an international research team involving KTH Royal Institute of Technology, RWTH Aachen University and Research Institute AMO GmbH, Aachen.

Among the conceivable applications are monitoring systems for cardiovascular diseases and ultra-sensitive wearable and portable motion-capture technologies.
