Benefits and downside of fasting

Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.

DNA replication mechanism in pluripotent stem cells

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic replication stress. However, a recent report challenges this assumption by providing a detailed molecular investigation of replication dynamics in these cells.

Human cells for cardiovascular research

The innermost layer of blood vessels is formed by endothelial cells, which in turn play a role in the development of diseases of the cardiovascular system. Human endothelial cells are therefore required for the 'in vitro' investigation of the causes of these diseases. Researchers have now established a highly efficient, cost-effective and reproducible way to generate functional endothelial cells from human induced pluripotent stem cells (hiPSCs) for tests in cell culture dishes.

Fighting leukemia by targeting its stem cells

Acute myeloid leukemia is one of the deadliest cancers. Leukemic stem cells responsible for the disease are highly resistant to treatment. A team has made a breakthrough by identifying some of the genetic and energetic characteristics of these stem cells, notably a specific iron utilization process. This process could be blocked, leading to the death or weakening of these stem cells without affecting healthy cells. These results pave the way for new therapeutic strategies.

Study points at novel approach to treat Group 3 medulloblastoma

A team of researchers has identified and located a population of stem-like cells that initiates and maintains Group 3 medulloblastoma (Gr3-MB) in the developing brain. Gr3-MB is one of the most aggressive forms of brain cancer in children and is associated with metastatic spread and poor survival. The researchers showed that eliminating the small population of stem-like cells present in Gr3-MB tumors led to tumor shrinkage in preclinical models. Although more research is needed, this novel approach may lead to new ways to treat children with Gr3-MB.

Ten(10) Slowest Animal Species

Ten(10) Slowest Animal Species

Gila Monster

Gila Monster is a venomous lizard. They walk on their shirt legs with their tail off the ground, swinging it from right to left.
it is the slowest lizard in the world. They live underground, hunt less, and store more fat in their bodies. They are heavy-bodied lizards with bead-like scales. The monster could be pink or black and yellow.

Koala

Koala has the power to save energy by moving slowly and sleeping. Koala has an extreme metabolic rate. When not sleeping, they’re likely eating. They have a strong digestive system to break down toxins after eating eucalyptus trees, that is their most favorite.

Banana Slug

Banana Slug slowly crawl with the help of mucus. Slug has a single lung with an external breathing pore. It eats with a tongue covered with rows of microscopic teeth. When the environment is too hot or dry they dwell in a shady shelter. They have one muscular foot that enables it to move.

Dugong

Dugong have a very slow swimming speed. Seagrass is their primary source of food. Dugong and manatees are similar in appearance but the former’s tail looks like that of a whale. Their tale is used for standing with the head above the water. Dugong live in coastal waters.

Dwarf Seahorse

Dwart Seahorse bladders enable them to swim, using gills to breathe. Seahorses are tough for other fish to swallow because of their bony bodies. They do not have natural predators other than crustaceans. Ritual dance is a way for seahorses to greet each other. Dwarf Seahorse is a type of fish with a horse-like head.

Start Fish

Starfish, also referred to as sea stars fish, is one of the slowest animal in the world.
They have tiny feet that help them grasp the ground to move around. Starfish can be found in both deep and shallow water.

They do not have a skeleton but a body composed of calcium carbonate plates known as “ossicles”. They do not have a brain or blood but a nervous system. This animal has five or more arms and can be quite large.
The average speed of Star fish is a metre per minute

Snail

Snail move efficiently, the snail releases mucus in order to reduce friction and to allow it to crawl very well over a rough surface, most especially to help their body from drying out. They have organs of both sexes, which makes them a hermaphrodite.Snail has a muscular organ that enables it to move extremely slowly.

Tortoise

Tortoise are very active during the day but slow-moving because of their slow metabolic rate. The shell of a tortoise is part of its bone structure and protects it from prey. The shell is a good absorber of heat from the sun — tortoise need this to survive because they are cold-blooded. The most famous species of tortoise that lives on land is the Galapagos tortoise; which can live up to 150 years.

Manatee

Manatee weigh like 3,500 pounds and are up to 13 feet long. Manatees are herbivores; they feed on saltwater plants and freshwater. Manatee, also known as sea cow, can be a little bit speedy compared to other slow animals but it is still usually slow. They are usually found in shallow coastal areas.

Three-toed Sloth

Three-Toed Sloths barely move. They spend days on treetops, feeding on fruits, shoots, and leaves. Their long arms enable them to reach a wider space without much movement. Sloths sleep between 15 and 20 hours every day. When on land, they use their claws to dig, and their belly and front legs to drag themselves along.They have low metabolic rate,
