UNC researchers find final pieces to the circadian clock puzzle
UNC researchers discovered how two genes -- Period and Cryptochrome -- keep the circadian clocks in cells in proper rhythm with the 24-hour day. The finding has implications for drug development for various diseases including cancer and conditions such as jetlag and season affective disorder.

Genetic testing can identify men at 6-fold increased risk of prostate cancer
Scientists can now explain one-hird of the inherited risk of prostate cancer, after a major international study identified 23 new genetic variants associated with increased risk of the disease.

New insights in survival strategies of bacteria
Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, e.g. during antibiotics treatment. A biofilm is a bacterial community surrounded by protective slime capsule consisting of sugar chains and 'curli.' VIB/VUB scientist have created a detailed 3-D image of the pores through which curli building blocks cross the bacterial cell wall, a crucial step in the formation of the protective slime capsule.

Measuring modified protein structures
ETH-Zurich researchers have developed a new approach to measure proteins with structures that change. This could enable new diagnostic tools for the early recognition of neurodegenerative diseases to be developed.

How an ancient vertebrate uses familiar tools to build a strange-looking head
In this study, Investigator and Scientific Director Robb Krumlauf, Ph.D., and colleagues show that the sea lamprey Petromyzon marinus, a survivor of ancient jawless vertebrates, exhibits a pattern of gene expression that is reminiscent of its jawed cousins, who evolved much, much later.

Asian monsoon much older than previously thought
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, an international research team led by a University of Arizona geoscientist reports in the journal Nature. Scientists thought the climate pattern known as the Asian monsoon began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains.

Muscular dystrophy: Repair the muscles, not the genetic defect
A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease.

Blood-cleansing biospleen device developed for sepsis therapy
Things can go downhill fast when a patient has sepsis, a life-threatening condition in which bacteria or fungi multiply in a patient's blood -- often too fast for antibiotics to help. A new device inspired by the human spleen and developed by a team at Harvard's Wyss Institute for Biologically Inspired Engineering may radically transform the way doctors treat sepsis.

Nature: New drug blocks gene driving cancer growth
When active, the protein called Ral can drive tumor growth and metastasis in several human cancers including pancreatic, prostate, lung, colon and bladder. Unfortunately, drugs that block its activity are not available. A study published today in the journal Nature uses a novel approach to target the activation of these Ral proteins.

Decoding 'sweet codes' that determine protein fates
The research group lead by Professor Koichi Kato of the Institute for Molecular Science, National Institutes of Natural Sciences developed a methodology for quantitatively describing the dynamic behaviors of complicated sugar chains in solution at atomic resolution by combining a sophisticated NMR spectroscopic approach with an ingenious molecular dynamics simulation technique. This study has just been published in Angewandte Chemie International Edition (published online on Sept.4, 2014).

Milestone reached in work to build replacement kidneys in the lab
Regenerative medicine researchers at Wake Forest Baptist Medical Center have addressed a major challenge in the quest to build replacement kidneys in the lab. Working with human-sized pig kidneys, the scientists developed the most successful method to date to keep blood vessels in the new organs open and flowing with blood. The work is reported in journal Technology.

USC researchers discover the healing power of 'rib-tickling'
Unlike salamanders, mammals can't regenerate lost limbs, but they can repair large sections of their ribs. In a new study in the Journal of Bone and Mineral Research, a team directed by USC Stem Cell researcher Francesca Mariani takes a closer look at rib regeneration in both humans and mice.

New glaucoma culprit is found
In a unique study of human ocular cells, a multi-institution team led by a Northwestern University biomedical engineer has found that endothelial cells in Schlemm's canal -- important for draining fluid from the eye -- are stiffer in eyes with glaucoma than those in healthy eyes. The resulting increased flow resistance is responsible for the elevated pressure associated with glaucoma. Therapeutic strategies that alter the stiffness of these cells could lead to a cure for this debilitating disease.

Boosting armor for nuclear-waste eating microbes
A microbe developed to clean up nuclear waste and patented by a Michigan State University researcher has just been improved. In earlier research, Gemma Reguera, Michigan State University microbiologist, identified that Geobacter bacteria's tiny conductive hair-like appendages, or pili, did the yeoman's share of remediation. By increasing the strength of the pili nanowires, she improved their ability to clean up uranium and other toxic wastes.

Getting hot and wet in Vermont
A fundamental challenge of climate change forecasting is how to bridge the gap between global-scale models and local impacts. A new study -- the first-of-its kind for the Lake Champlain region -- bridges this gap and forecasts that northern Vermont and southern Quebec by 2100 will get eight degrees Fahrenheit hotter; Burlington, Vt., will experience 10 more days in July above 90; and ski resorts will see 50 percent less snowfall.

CCNY analysis explains rich bird biodiversity in Neotropics
Applying analyses designed by City College of New York biologist Mike Hickerson, a team of international researchers is challenging a commonly held view that explains how so many species of birds ended up in the Neotropics, an area rich in rain forest extending from Mexico to the southernmost tip of South America. It is home to the most bird species on Earth.

Dendritic cells affect onset and progress of psoriasis
Different types of dendritic cells in human skin have assorted functions in the early and more advanced stages of psoriasis report researchers in the journal EMBO Molecular Medicine. The scientists suggest that new strategies to regulate the composition of dendritic cells in psoriatic skin lesions might represent an approach for the future treatment of the disease.

Piglet health
Parasitologists from the University of Veterinary Medicine of Vienna are closer to understanding the disease process behind porcine neonatal coccidiosis. The disease affects piglets during the first days of their life and can cause heavy diarrhea in the animals. The parasite Cystoisospora suis damages the intestinal mucosa to such a degree that it threatens the growth and survival of the pigs. The researchers have now analyzed the immune response to the infection. The results were published in the journal Parasite Immunology.

From worm muscle to spinal discs
Thoughts of the family tree may not be uppermost in the mind of a person suffering from a slipped disc, but those spinal discs provide a window into our evolutionary past. They are remnants of the first vertebrate skeleton, whose origins now appear to be older than had been assumed. Scientists at EMBL Heidelberg have found that, unexpectedly, this skeleton most likely evolved from a muscle.
