Does hotter mean healthier?
Phytophthora blight, caused by Phytophthora capsici, is a major plant disease that affects many crop species worldwide, including chile peppers in New Mexico. Farmers' observations suggested that Phytophthora capsici caused less damage in pepper crops of the hot pepper varieties than low-heat pepper varieties. view more (2009-02-04)
A Chilling Solution: Measuring Below-ground Carbon Without Destroying Trees
USDA Forest Service (FS) researchers have provided the first proof of concept for a method that allows scientists to study below-ground carbon allocation in trees without destroying them. view more (2006-12-06)
The sap flow through trees.
The transport of water through trees Trees take up water from the soil by their root hairs and transport it through the vessels of the stem towards the leaves. At leaf level this water evaporates and comes into the atmosphere through little pores in the leaf epidermis, called stomates. This process is also known as transpiration. The water... view more...

Robust time estimation reconciles views of the antiquity of placental mammals
Despite great progress over the past decade, the evolutionary history of placental mammals remains controversial. While a consensus is emerging on the topology of the evolutionary tree, although with occasional disagreement, divergence times remain uncertain. view more (2007-04-18)
Bursting buds are dicing with death
Scientists from the John Innes Centre (JIC), Norwich (1) have today reported that highly toxic compounds, called free radicals, are essential to plant growth. The researchers had found that the controlled production of free radicals is an essential first step in switching on the expansion of cells that underlies the growth of plant shoots, roots,... view more...

Brazilians judge facial beauty differently than North Americans
Standard ideals of facial beauty and harmony may differ depending on geographic location, with a specific difference between North American beauty ideals and those of Brazilians. view more (2009-10-05)
Key root-development pathway mapped using advanced genomic technique
Biologists have vastly expanded understanding of the biological machinery controlling the intricate process by which plant roots burgeon from single cells into complex tissues. view more (2006-05-05)
Reconstructing mandibular defects with bioengineered tooth and bone
Current strategies for jaw reconstruction require multiple procedures, first to repair the bone defect to offer sufficient support, and then to place the tooth implant. view more (2008-04-07)
Researchers offer clues to how leaf patterns are formed
Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a big clue to how those patterns are formed. view more (2006-06-16)
Rogue trees get criminal treatment from scientists
Rogue trees are being ‘fingered’ by gene detectives using a well-known technique to catch criminals. Newcastle University scientists are using DNA fingerprinting to help insurers identify trees that are causing houses to subside. Often disputes can last for several years, as when two trees of the same kind grow in an area it is very... view more... (2002-08-27)
Ultrasound may help regrow teeth
Hockey players, rejoice! A team of University of Alberta researchers has created technology to regrow teeth—the first time scientists have been able to reform human dental tissue. view more (2006-06-29)
China quake rare and unexpected, says new MIT study
A new analysis of the setting for last month's devastating earthquake in China by a team of geoscientists at MIT shows that the quake resulted from faults with little seismic activity, and that similar events in that area occur only once in every 2,000 to 10,000 years, on average. view more (2008-07-01)
Deep-sea species' loss could lead to oceans' collapse, study suggests
The loss of deep-sea species poses a severe threat to the future of the oceans, suggests a new report publishing early online on December 27th and in the January 8th issue of Current Biology, a publication of Cell Press. view more (2007-12-28)
New research finds possible genetic link to cause of pregnancy loss and disorders
Scientists at the University of Tennessee, Knoxville, and Lawrence Berkeley National Laboratory (LBNL) have published new findings about a cause of a condition at the root of genetic disorders such as Down Syndrome, pregnancy loss and infertility. view more (2009-07-22)
Plants recognize their siblings, biologists discover
The next time you venture into your garden armed with plants, consider who you place next to whom. It turns out that the docile garden plant isn't as passive as widely assumed, at least not with strangers. view more (2007-06-14)
Sweet potato takes a ride on space shuttle
Because of the distinct lack of grocery stores in outer space, scientists are looking for ways to provide food for long-term space missions. view more (2009-02-18)
Bacterial Protein Shows Promise in Treating Intestinal Parasites
Scientists at the University of California, San Diego and Yale University have discovered that a natural protein produced by Bacillus thuringiensis, a bacterium sprayed on crops by organic farmers to reduce insect damage, is highly effective at treating hookworm infections in laboratory animals. view more (2006-09-26)
No longer a gray area: Our hair bleaches itself as we grow older
Wash away your gray? Maybe. A team of European scientists have finally solved a mystery that has perplexed humans throughout the ages: why we turn gray. view more (2009-02-24)
Superscanner helps scientists see into the unknown
Researchers at The University of Nottingham have a new weapon in their arsenal of tools to push back the boundaries of science, engineering, veterinary medicine and archaeology. view more (2009-09-11)
Subsidence: DNA profiling roots out offending trees
A new spinout company from the University of Leeds is laying claim to the most accurate identification of trees causing subsidence - using methods that could save the insurance industry millions in time and costs in disputed cases. Identi-Tree Ltd has been launched by the University's commercialisation partner, Techtran Group Ltd. Identi-Tree is... view more... (2004-04-26)
