Researchers using three dimensional computer modeling and wind tunnels have made the first accurate comparative measurements of muscle power output of birds in-flight to establish that physical structure, body mass, force and flight style all have major effects upon the magnitude and shape of a species’ power curve.
The research by Harvard integrative physiologist Andrew A. Biewener and fellow researchers was publicly funded through the National Science Foundation (NSF) and published in the
Scientists at the University of Leicester are on the way to solving a problem that has long beset chemists trying to study chemical reactions.
To establish reaction mechanisms the observation of reaction intermediates is vital, but they are incredibly short-lived under normal conditions, and therefore difficult to detect. Freezing the reaction – known as matrix isolation – has been employed for many years, but produces rigid solids in which molecules are trapped and therefore motionle
In a recent study, giving iron supplements to anemic children when they have a cold or other upper respiratory tract infection (URTI) significantly improved their iron status without increasing stomach upset or other side effects, says a Penn State nutritionist.
Dr. Namanjeet Ahluwalia, associate professor of nutrition and principle investigator on the research team, says, “Because of conflicting results from previous studies, physicians preferred to be cautious and generally withhold iron
In a milestone for global science collaboration, CERN took delivery today of the first US-built contribution to what will be the world’s highest-energy particle accelerator. The superconducting magnet, built at the US Brookhaven National Laboratory will become a key component of the Large Hadron Collider (LHC).
It is the first of several advanced accelerator elements the US will provide for the LHC under the terms of a 1998 agreement between CERN and the US Department of Energy (DOE)
Binghamton University researcher fractures myths around osteoporosis
Osteoporosis is not a disease, and neither weight-bearing exercise nor calcium supplements-not even a combination of the two-is capable of triggering the growth of new bone, says Kenneth McLeod, chair of the bioengineering department at Binghamton University and a leading researcher in the field of tissue development, healing and adaptation.

Expert in ‘emotional communication’ says 1-year-olds can pick up ‘emotional signals’ and base decisions on them
What do infants learn as they watch people talk or act in a certain manner? If a television is on in a room, how much do infants pay attention to it?
These are questions Donna Mumme, assistant professor of psychology at Tufts University, answers in her study, “The Infant as Onlooker: Learning from Emotional Reactions Observed in a Television Scenario.” Co-authored
