Compact Cas7-11 Enzyme for RNA Editing: CRISPR-Cas System

June 1, 2022June 1, 2022 Pooja Kashyap

The CRISPR CAS9 system famously known as genetic scissors was discovered by Emmanuelle Charpentier and Jennifer Doudna in 2012. And since then, the new tool has been studied extensively across global academia. Initial studies of the genome editing tool altered only the DNA. However, lately the CAS system is also studied for editing RNA. What is CRISPR-CAS system? CRISPR-CAS system is an adaptive immune system of bacteria, which protects it from invaders. Also, it defends the bacterial host from renewed infection as it memorizes previous infections. DNA has the fingerprint.…

Multiple Modes of Dendritic Integration in Single Neurons: Brain Computation

March 11, 2022March 11, 2022 Pooja Kashyap

Dendrites, branch like extensions protruding from a single neuron, participate in computations and permutations to give a synchronized output to the neuron. Researchers at MIT have now demonstrated that not only different types of dendrites (of a single neuron) collect input from various regions of the brain, they also process that information in different customized ways.

Maneuvering Brain Astrocytes via Magnetic Field: Magnetomechanical Stimulation

March 3, 2022March 3, 2022 Pooja Kashyap

Researchers at University College London have discovered a new form of non-invasive therapy for neurological disorders. The technique called “magnetomechanical stimulation” (MMS) involves microscopic magnetic particles for remotely stimulating brain cells.

Altering Macrophage Metabolism Helps Damage Nerves Recover: Neuronal Health

October 9, 2021October 9, 2021 Pooja Kashyap

Peripheral nervous system (PNS) axons regenerate in contrast with central nervous system (CNS) axons, however, the rate of renewal is fairly slow. It is because of its sluggish rate majority of the peripheral nerve injuries lead to permanent disability for patients.

Skin Cells Reprogrammed into Early Embryos: Stem Cell Research

March 18, 2021March 18, 2021 Pooja Kashyap

In an interesting research, scientists made an unbelievable attempt of creating early human embryo from skin cells! An international team of researchers led by Monash University Australia has developed a model that resembles human embryo from skin cells.

Microfluidic Squeezing Leads To Stemness: Cell Engineering

October 16, 2020October 16, 2020 Pooja Kashyap

In an interesting finding, scientists at Massachusetts Institute of Technology and Boston Children’s Hospital have discovered that physically pressing microscopic intra-cellular structures together can trigger cells to grow faster. This phenomenon at microscopic level resembles the spread of things like ideas, interests and even infections within a close proximity of people.

Memory Consolidation via Excitatory And Inhibitory Networks: Neuronal Circuits

October 9, 2020October 9, 2020 Pooja Kashyap

Until now, neuroscientists believed that during memory consolidation only “one” excitatory process occurs and that also in the Hippocampus region of the brain. Lately, McGill-led multi-institutional research team has discovered that there is not one but two different processes that are simultaneously taking place in different neural network within brain.

Specialized Grafts Behaved Like Neurons: Spinal Cord Injury

August 7, 2020August 7, 2020 Pooja Kashyap

A spinal cord injury (SCI) usually causes perpetual damage within our body. This can result in long-term disability. And in most of the cases, spinal cord compression can lead to paralysis.

10 Amazing Brain Facts: The Most Complex Manifestation of Intelligence

June 23, 2020August 17, 2021 Pooja Kashyap

Study of human brain is one of the most remarkable subjects of all times. The more we learn, the more questions we have, this holds true for the wide network of neurons that we all carry above our head, literally.

Can you be allergic to water: Aquagenic Urticaria

May 21, 2020May 29, 2020 Pooja Kashyap

Earth is a watery planet, in fact, water covers nearly 71 percent of our planet. It exists in our atmospheric air as water vapor and in ground flora as moisture within the soil. Water is one of the main components that we look for in extra-terrestrial planetary space.

Molecules That Could Delay Aging Discovered: Achieving Healthy Longevity

September 9, 2016September 9, 2016 Neha Shukla

With ageing come problems like sagging skin, brittle bones, hearing loss, deteriorating mind and many other issues. Aging is an inevitable process however, science has helped in prolonging this certainty.

3D Bioprinting Would Help Bones Regenerate Without Using Grafts: Printing Prosthetics

September 8, 2016May 29, 2020 Neha Shukla

Dublin based research team has successfully developed a procedure of 3D bioprinting to design new cartilage templates in the shape of missing bones. This bioprinted template will be implanted in the body to regenerate new bones to fix major injuries and bone defects. Traditionally, such injuries and bone defects require some form of bone grafts that are painful and invasive and often have complications of its own.

Regeneration of Eye’s Outermost Layer via Hydrogel Films: Corneal Transplantation

August 23, 2016August 23, 2016 Neha Shukla

In a breakthrough study, a team of scientists from the Melbourne University has achieved success in growing cornea cells in the laboratory. Scientists have successfully implanted laboratory grown cornea cells in the eyes of sheep. They are expecting to begin clinical trials in humans soon.

Obesity May Trigger The Progression Of Brain Ageing: Neurobiology Of Aging

August 4, 2016 Pooja Kashyap

Over the years, various researches across neurobiology of aging have suggested that brain shrinks with age. A recent study led by the University of Cambridge has added that obesity may also trigger the progression of brain ageing.

Bionic Eye allows blind man to see again: The Eyeborg

July 24, 2015 Neha Shukla

Experts at Manchester Royal Eye Hospital have successfully restored the vision of 80 years old Ray Flynn, through implanting ‘bionic eye’. For the last eight years, Mr Flynn suffered from dry age-related muscular degeneration (AMD). AMD is a condition in which photoreceptor cells in the central region of the retina are damaged leading to loss of central vision. The condition is very common, affecting nearly 5,00,000 people in the UK.
