Botanist and environmentalist Peter Raven has been recognized by the Chinese Academy of Sciences.

These tubes or capillaries, formed by a single cell, connect the main tubes of the respiratory system with organs and tissues, thereby providing oxygen.

Using cryo-electron microscopy and advanced image-processing methods, UCLA researchers have developed a model of how the potentially therapeutic vesicular stomatitis virus assembles.

Cellular imaging offers a wealth of data about how cells respond to stimuli, but harnessing this technique to study biological systems is a daunting challenge.

Certain people carry a genetic variant that could shave three or four years off their life, according to a new study.

PROVIDENCE, R.I. [Brown University] - Around 30 to 40 million years ago, grasses on Earth underwent an epic evolutionary upheaval.

The first head-to-head comparison of therapeutic monoclonal antibodies produced from plants versus the same antibodies produced from mammalian cells has shown that plant-produced antibodies can fight infection equally well.

A Jamaican jury has convicted a U.S.-born botanist of conspiring to kill his wife on the Caribbean island.

Scientists announced they have identified for the first time definitive variants associated with biological ageing in humans. The team analyzed more than 500,000 genetic variations across the entire human genome to identify the variants which are located near a gene called TERC.

Tiny circles of DNA are the key to a new and easier way to transform stem cells from human fat into induced pluripotent stem cells for use in regenerative medicine, say scientists at the Stanford University School of Medicine.

The team analyzed more than 500,000 genetic variations across the entire human genome to identify the variants which are located near a gene called TERC.

Patients who have high cardiovascular risks have fewer endothelial progenitor cells and their EPCs exhibit greater in vitro senescence.

Something is holding down the herring population of Alaska's Prince William Sound, and marine scientists are tailing some rather large suspects: humpback whales.

Understanding how aged and damaged mother cells manage to form new and undamaged daughter cells is one of the toughest riddles of ageing, but scientists now know how yeast cells do it.

Now, scientists at Cambridge have found "hotspots" in the butterflies' genes that they believe will explain one of the most extraordinary examples of mimicry in the natural world.

Feb. 3, 2010 - Dr. Kim Orth , associate professor of molecular biology at UT Southwestern Medical Center, was honored today with the 2010 Norman Hackerman Award in Chemical Research for pioneering work focusing on the mechanisms bacteria use to cause disease.

The future of medical electronics could turn on the arrival of a new class of nanoscale chips that can monitor and deliver personalized therapies to human cells.

A novel finding, described today on the Science Express Web site by teams from the National Cancer Institute, The University of Texas Health Science Center at San Antonio and the University of Toronto, offers a clue as to how genes can have what you might call multiple personalities.

Within a virus's tiny exterior is a store of energy waiting to be unleashed. When the virus encounters a host cell, this pent-up energy is released, propelling the viral DNA into the cell and turning it into a virus factory.

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting, in Chicago, researchers will unveil findings that show that it is not cost effective to screen for spinal muscular atrophy.
