Molecular biologists reveal new insights into tumor progression

When viewed under a fluorescence microscope, the individual probes illuminate each RNA in a single cell. Using a color combination method, UD molecular biologist Mona Batish can distinguish which labeled RNAs are linear (yellow) and circular (green). Picture credits: Kathy F. Atkinson Molecular biologist Mona Batish of the University of Delaware and associates at Harvard Medical School and the University …

Biologists created an "eyeball on a chip" that actually flashes

Penn Engineering Researchers at the School of Engineering and Applied Science at the University of Pennsylvania have developed a replica of the human eye that can actually blink. But do not worry, they will not work with the researchers who build robotic muscles to assemble Skynet's first Terminators. They use it to develop the treatment of eye diseases. The eye …

Biologists rebuild the microtubules, which make up cell walls and spindles

PhD student Akanksha Thawani (left) discusses her research with molecular biologist Sabine Petry. Thawani, Petry and their colleagues at Princeton have been able to reconstruct the recipe for the fireworks of life, the branched microtubules that make up the cell walls, and the spindles for mitosis and meiosis.

Biologists identify "pure" genes from honeybees that are known for improving survival

Credit: CC0 Public Domain The key to breeding disease-resistant honeybees may lie in a set of genes that are known to control sanitary behavior and allow colonies to restrict the spread of harmful mites and bacteria, according to the York University Genome Research. Some honey bees detect and remove diseased and dead larvae and pupae from their colonies. This hygienic …

Bizarre deep-sea fish that live in the Gulf of California and are virtually deoxygenated confuse biologists

Among the species of fish discovered in the depths of the Gulf of California were dogfish and farm-eared eels. (2015 Monterey Bay Aquarium Research Institute) Deep in the dark depths of the Gulf of California – where "virtually no oxygen" is present, live schools of fish live and thrive in an environment that would otherwise be fatal to marine biologists …

Biologists discover an unusual sign of aging in neurons

Neurons from 19-month-old mice (bottom row) show much higher oxidative stress than neurons from 9-week-old mice (top row). Lipofuscin, a molecule associated with alternative oxidative stress, appears red. Picture credits: Hyeseung Lee As we age, neurons in our brain can be damaged by free radicals. MIT biologists have now discovered that this type of injury, known as oxidative stress, produces …

Biologists are studying rapid evolutionary changes in acorn insects

Case Western Reserve biologists are exploring (d) the potential for parallel (and non-parallel) development of thermal tolerance in three cities using acorn ants as a model ants are "very sensitive to temperature , including in their development rate, running speed and thermal tolerance ", according to their newspaper. Credit: Lauren Nichols, Case Western Reserve University The relatively rapid adaptability of …

Biologists find in the North Atlantic the meeting place of the Baby White Sharks

18th July (UPI) – Using next-generation satellite and acoustic technology, marine biologists have identified migratory patterns and Hangouts of Great White Sharks in the North Atlantic. Researchers have long suspected that the New York Bight, a seabed running from New Jersey's Cape May Inlet to Montauk Point on the eastern tip of Long Island, serves as a breeding ground for …
