UCLA researchers have discovered a type of cell that is the “missing link” between bone marrow stem cells and all the cells of the human immune system, a finding that will lead to a greater understanding of how a healthy immune system is produced and how disease can lead to poor immune function.
The research was done using human bone marrow, which contains all the stem cells that produce blood during post-natal life. (more…)
EAST LANSING, Mich. — Witch hunts are common and sometimes deadly in the tea plantations of Jalpaiguri, India. But a surprising source – small groups of women who meet through a government loan program – has achieved some success in preventing the longstanding practice, a Michigan State University sociologist found.
Soma Chaudhuri spent seven months studying witch hunts in her native India and discovered that the economic self-help groups have made it part of their agenda to defend their fellow plantation workers against the hunts. (more…)
The Pink Double Dandy peony, the Double Peppermint petunia, the Doubled Strawberry Vanilla lily and nearly all roses are varieties cultivated for their double flowers.
The blossoms of these and other such plants are lush with extra petals in place of the parts of the flower needed for sexual reproduction and seed production, meaning double flowers – though beautiful – are mutants and usually sterile.
The genetic interruption that causes that mutation helped scientists in the 1990s pinpoint the genes responsible for normal development of sexual organs stamens and carpels in the plant Arabidopsis thaliana, long used as a plant model by biologists. (more…)
UD scientist sees Arctic ice loss firsthand
The extent of sea ice in the Arctic has reached a record low, according to data released Aug. 26 by the U.S. National Snow and Ice Data Center (NSIDC).
A University of Delaware marine scientist can confirm some of that ice loss firsthand. In a short video he produced, Andreas Muenchow, aboard the Canadian icebreaker Henry Larsen, shows the ice-free sea off Petermann Fjord that he and his colleagues were sailing in — an area that for ages had been covered by floating ice shelves.

A UA study has found poverty, water scarcity, food insecurity and interdependence between the United States and Mexico along the border.
The U.S.-Mexico border is the border in the world with the greatest disparity in access to food and water needed for human survival, according to a report commissioned and published by the Southwest Center at the University of Arizona.
An endowment from the Kellogg Foundation and a UA Confluencenter for Creative Inquiry grant supported the study and its focus on assessing transborder food systems to understand water scarcity and food insecurity within the borderlands region.
The report underscores how in the globalized economy, Arizona and the rest of the United States rely on the skilled labor, water, fresh produce, fish, shellfish and livestock originating in northern Mexico; while in Mexico, the population is increasingly dependent upon frozen and processed foods originating in the United States.

Berkeley Lab scientists and their colleagues have successfully probed the effects of light at the atomic scale by mixing x-ray and optical light waves at the Linac Coherent Light Source
Light changes matter in ways that shape our world. Photons trigger changes in proteins in the eye to enable vision; sunlight splits water into hydrogen and oxygen and creates chemicals through photosynthesis; light causes electrons to flow in the semiconductors that make up solar cells; and new devices for consumers, industry, and medicine operate with photons instead of electrons. But directly measuring how light manipulates matter on the atomic scale has never been possible, until now. (more…)
