Under the Electron Microscope – A 3-D Image of an Individual Protein

The high resolution of Lawrence Berkeley National Laboratory’s Gang Ren

When Gang Ren whirls the controls of his cryo-electron microscope, he compares it to fine-tuning the gearshift and brakes of a racing bicycle. But this machine at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) is a bit more complex. It costs nearly $1.5 million, operates at the frigid temperature of liquid nitrogen, and it is allowing scientists to see what no one has seen before. (more…)

2012 Economic Forecast from UMD Business Faculty

COLLEGE PARK, Md. – A weak housing market, tight credit for small businesses, no significant growth in the banking sector, anemic consumer spending, and modest sales for retailers – that’s the outlook for 2012 according to experts at the University of Maryland’s Robert H. Smith School of Business. (more…)

Winged Dinosaur Archaeopteryx Dressed For Flight

*The iconic, winged dinosaur Archaeopteryx was dressed for flight, an international team of researchers led by Brown University has concluded. The group identified the color of the raven-sized creature’s fossilized wing feather, determining it was black. The color and the structures that supplied the pigment suggest that Archaeopteryx’s feathers were rigid and durable, which would have helped it to fly. Results appear in Nature Communications.*

PROVIDENCE, R.I. [Brown University] — Since its discovery 150 years ago, scientists have puzzled over whether the winged dinosaur Archaeopteryx represents the missing link in birds’ evolution to powered flight. Much of the debate has focused on the iconic creature’s wings and the mystery of whether — and how well — it could fly. (more…)

Microsoft Provides Tips to Help Protect Your Online Image

*Microsoft encourages individuals to examine their online reputation and offers tips to start the new year with the best digital foot forward.*

REDMOND, Wash. — Jan. 24, 2012 — In observance of Data Privacy Day 2012, Microsoft Corp. is releasing new data about consumer behaviors online and is offering guidance and tips to help people better manage their online profiles and maintain a positive reputation.

Vision Improves Modestly in Patients after Human Embryonic Stem Cells Transplants

Researchers at UCLA’s Jules Stein Eye Institute and colleagues who successfully transplanted specialized retinal cells derived from human embryonic stem cells into the eyes of two legally blind patients report that the transplants appear safe and that both patients have experienced modest improvement in their vision.

The preliminary findings, published online Jan. 23 in the journal The Lancet, represent a milestone in the therapeutic use of stem cells and may pave the way for a new therapy to treat eye diseases, the researchers said. Because this is the first time physicians have applied the power of regenerative medicine to eye disease, the clinical trials are being watched closely by scientists, stem-cell therapy advocates and the public.

New U-M Computer Model Predicts Cholera Outbreaks Up To 11 Months in Advance

ANN ARBOR, Mich.— A new University of Michigan computer model of disease transmission in space and time can predict cholera outbreaks in Bangladesh up to 11 months in advance, providing an early warning system that could help public health officials there.

The new forecast model applies specifically to the capital city of Dhaka and incorporates data on both year-to-year climate variability and the spatial location of cholera cases at the district level. This allowed the researchers to study both local variation in disease transmission and response to climate factors within the megacity of 14 million people. (more…)

Gene Research Sheds Light on Timing of Menopause

An international team of researchers has discovered 13 new regions of the genome associated with the timing of menopause.

These genes shed light on the biological pathways involved in reproductive lifespan and will provide insights into conditions connected to menopause, such as breast cancer and heart disease.

Menopause is a major hormonal change that affects most women when they are in their early 50s. The timing of menopause can have a huge impact on fertility, as well as influencing the risk of a range of common diseases such as breast cancer. It has been known for some time that genetic factors influenced the onset of menopause, however until recently very few genes had been identified.

In the new study, published in the journal Nature Genetics on 22 January 2012, Dr Anna Murray, University of Exeter, Peninsula College of Medicine and Dentistry (PCMD) Dr John Perry, PCMD and WTCHG, University of Oxford, and dozens of international collaborators, examined the genomes of over 50,000 women. They identified 13 novel gene regions associated with menopause onset, and confirmed four previously identified. Most of the 17 regions include genes related to DNA damage/repair or the immune system, whilst others are linked to hormonal regulation. (more…)
