Buckling could trigger embryo morphogenesis

The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.).

Research provides insight into how muscles and fat tissue communicate to improve fitness

Why does exercise training make you more fit? It's well established that exercising enhances insulin sensitivity and improves our metabolism that, in turn, increases exercise performance. But the biological mechanisms underlying this adaptation are not fully understood.

SMART researchers discover a new way to manufacture human red blood cells

Researchers from Singapore-MIT Alliance for Research and Technology, MIT's research enterprise in Singapore, have discovered a new way to manufacture human red blood cells (RBCs) that cuts the culture time by half compared to existing methods and uses novel sorting and purification methods that are faster, more precise and less costly.

DNA damage may occur far away from the point of incidence of radiation

Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers of Karlsruhe Institute of Technology have demonstrated that DNA damage may also occur far away from the point of incidence of the radiation.

Scientists shed new light on gene regulatory pathways activated by stress hormone

Scientists have long known that chronic stress experienced early in life, or even chronic prenatal exposure to maternal stress hormones in the womb, can shorten lifespan and contribute to age-related chronic diseases like arthritis, asthma, cancer, cardiovascular disease, diabetes and even mental illness later in life -- long after the source of stress has been removed.

Unique temporal-spatial order property of HoMSs can realize sequential drug release

Hollow multishelled structures (HoMSs), with relatively isolated cavities and hierarchal pores in the shells, are structurally similar to cells. They can be used as a carrier for antibacterial agent.
