A study from the University of Pittsburgh School of Medicine and the McGowan Institute for Regenerative Medicine identifies a mechanism by which bioscaffolds used in regenerative medicine influence cellular behavior, a question that has remained unanswered since the technology was first developed several decades ago. The findings were recently published online in Science Advances.

Patients with obstructive sleep apnea (OSA) face an elevated risk of perioperative complications; the risk is even higher if the diagnosis has not been made before surgery. This is so for many OSA patients, as Philipp Fassbender and colleagues point out in a review in the current issue of Deutsches Ärzteblatt International (Dtsch Arztbl Int; 2016; 113: 463-69).
KRAKOW, POLAND - In order to introduce new flowering plants to market, breeders and growers need proven strategies for producing healthy, compact plants during times of highest consumer demand. Determining optimal planting times to produce true-to-type, high-quality potted plants or cut flowers also translates to higher revenues for growers. A new study in June 2016 issue of HortTechnology offers recommendations about production practices for lachenalia, an ornamental plant that is gaining popularity among consumers.
DALLAS - July 28, 2016 - UT Southwestern Medical Center researchers have identified a new way to target lung cancer through the KRAS gene, one of the most commonly mutated genes in human cancer and one researchers have so far had difficulty targeting successfully.
Researchers studying the underlying biology of KRAS in lung cancer determined that activity resulting from the ACSL3 gene is essential for these lung cancer cells to survive, and that suppressing ACSL3 causes these lung cancer cells to die.
Some people love avocados. Others hate them. For many of the latter, the fruit's texture is the source of their intense dislike. What gives?
Scientists do not have a clear understanding of the exact process by which food texture is sensed. But now, a new study by UC Santa Barbara biologist Craig Montell and his research team sheds light on how fruit flies "feel" foods based on two important textural features -- viscosity and hardness. Their findings appear in the journal Neuron.
BIRMINGHAM, Ala. - Though the drug levodopa can dramatically improve Parkinson's disease symptoms, within five years one-half of the patients using L-DOPA develop an irreversible condition -- involuntary repetitive, rapid and jerky movements. This abnormal motor behavior appears only while taking L-DOPA, and it stops if the drug is stopped. However, if L-DOPA is taken again, even many months later, it quickly re-emerges.
In tough times, humans aren't the only species that think twice about having children. Consider roundworm strain LSJ2.
Though it can't think - much less think twice -- about anything, the laboratory worm underwent a mutation that made it prioritize the survival of adults over creating abundant offspring. Researchers noticed the change in behavior and the mutation after LSJ2 faced hardship for 50 years.
New research from the University of British Columbia suggests evolution is a driving mechanism behind plant migration, and that scientists may be underestimating how quickly species can move.
The study, published today in the journal Science, builds on previous research that has shown some plants and animals are moving farther north or to higher altitudes in an effort to escape rising global average temperatures due to climate change.
CHAPEL HILL - Women were less likely to have breast reconstruction surgery after mastectomy if they had Medicaid or Medicare rather than private insurance or if they lived 10 or more miles from a plastic surgeon's office, a University of North Carolina Lineberger Comprehensive Cancer Center study has found.
A new acoustic buoy recently deployed by scientists from the Woods Hole Oceanographic Institution (WHOI) and WCS's (Wildlife Conservation Society) New York Aquarium to listen for some of the world's biggest animals in the New York Bight has detected its first whale species, and it's a really big one.
Chestnut Hill, MA (July 28th, 2016): More isn't necessarily better when it comes to men making decisions together, especially if you want a middle-of-the-road compromise. That's according to a new study in the Journal of Consumer Research which finds that compromise always occurs among two decision makers when a woman is involved (female-female pairs or mixed gender pairs), but hardly ever when the pair of decision makers are men. The findings could be pertinent to marketers, managers, and consumers alike.
Leesburg, VA, July 26, 2016-- Given the anticipated increase in cancer imaging over the next decade [1, 2], radiologists need to solidify their position as central members of the cancer team by identifying toxicity early and understanding the implications of their findings.
Researchers from Princeton University and the University of California-Los Angeles who investigated the genetic ancestry of North America's wild canines have concluded that the U.S. Fish and Wildlife Service's scientific arguments for removing gray wolves from endangered species protection are incorrect.
Employees of the Department of Celestial Mechanics and Astrometry NII PMM of Tomsk state university (Russia) and colleagues from St. Petersburg State University, Keldysh Research Center, and Research Institute Sirius are developing measures to protect the Earth from potentially dangerous celestial bodies. With the help of supercomputer SKIF Cyberia, the scientists simulated the nuclear explosion of an asteroid 200 meters in diameter in such a way that its irradiated fragments do not fall to the Earth.
In a cross-sectional analysis published online today in the American Journal of Clinical Nutrition*, researchers looked at the association between habitual nut consumption and inflammatory biomarkers among 5,013 men and women participating in two ongoing prospective cohort studies: the Nurses' Health Study and Health Professionals Follow-up Study. Higher nut intake (5 or more times per week) was associated with lower levels of C-reactive protein (CRP) and Interleukin 6 (IL6).
