Discovery to hasten new malaria treatments, vaccines for children
April 25 is World Malaria Day 2008 and despite the grim statistics out of Africa there's cause for celebration. Florida State University biologists have discovered an autoimmune-like response in blood drawn from malaria-infected African children that helps to explain why existing DNA-based anti-malaria vaccines have repeatedly failed to protect them.


Arctic marine mammals on thin ice
The loss of sea ice due to climate change could spell disaster for polar bears and other Arctic marine mammals. The April Special Issue of Ecological Applications examines such potential effects, puts them in historical context, and describes possible conservation measures to mitigate them.




Catching a Glimpse of a Black Hole's Fury
Using the National Science Foundation's (NSF) Very Long Baseline Array (VLBA) and a host of international telescope partners, a team of researchers has made the clearest observation yet of innermost region of a black hole.


Environment influences when drinking begins; genes' role increases in transition to alcohol dependence
The influence of genetics increases as young women transition from taking their first drink to becoming alcoholics.


New source for biofuels discovered
A newly created microbe produces cellulose that can be turned into ethanol and other biofuels, report scientists from The University of Texas at Austin who say the microbe could provide a significant portion of the nation's transportation fuel if production can be scaled up.


Pregnancy is possible after cancer treatment
It has been reported for the first time in Germany that healthy ovarian tissue has been taken from a non-pregnant woman with cancer and then re-implanted after cancer therapy.


Galaxies gone wild!
Interacting galaxies are found throughout the Universe, sometimes as dramatic collisions that trigger bursts of star formation, on other occasions as stealthy mergers that result in new galaxies.


Sexual harassment at school - more harmful than bullying
Schools' current focus on bullying prevention may be masking the serious and underestimated health consequences of sexual harassment, according to James Gruber from the University of Michigan-Dearborn and Susan Fineran from the University of Southern Maine in the US.


Plan to identify watery Earth-like planets develops
Astronomers are looking to identify Earth-like watery worlds circling distant stars from a glint of light seen through an optical space telescope and a mathematical method developed by researchers at Penn State and the University of Hawaii.


Medical College researchers find dinosaur clues in fat
A team of researchers at New York Medical College has discovered why birds, unlike mammals, lack a tissue that is specialized to generate heat.


Sierra Nevada rose to current height earlier than thought, geologists say; implications for modeling global climate
Geologists studying deposits of volcanic glass in the western United States have found that the central Sierra Nevada largely attained its present elevation 12 million years ago, roughly 8 or 9 million years earlier than commonly thought.


Scientists urged to make a stand on climate
Scientists must work harder at making the public aware of the stark difference between good science and "denialist spin".


Heart derived stem cells develop into heart muscle
Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells.


1600 Eruption Caused Global Disruption
The 1600 eruption of Huaynaputina in Peru had a global impact on human society, according to a new study of contemporary records by geologists at UC Davis.


Nanotubes grown straight in large numbers
Duke University chemists have found a way to grow long, straight cylinders only a few atoms thick in very large numbers, removing a major roadblock in the pursuit of nano-scale electronics.


Researchers identify new cell targets for preventing growth of breast and other tumors
Researchers at the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill have discovered new targets for cancer treatment aimed at blocking a key step in tumor progression.


Researchers reveal structure of protein that repairs damage to cancer cells
A team of University of Chicago scientists has shown how two proteins locate and repair damaged genetic material inside cells.


Presence of certain antibodies signals healthier teeth and gums
Antibodies present in people with good oral health could become the first tool for dental professionals to assess a patient's probable response to periodontal disease treatments, say researchers at the University of Michigan.


Breast Reconstruction Advances Fix Distortions Left by Lumpectomy
Lumpectomy or breast conservation surgery is the most common type of breast cancer surgery currently performed. A benefit of the surgery is that only part of the breast is removed, but a drawback can be the resulting physical appearance of the breast, which may be disfigured, dented or uneven.


Researchers identify new cell targets for preventing growth of breast and other tumors
Researchers at the Lineberger Comprehensive Cancer Center at the University of North Carolina at Chapel Hill have discovered new targets for cancer treatment aimed at blocking a key step in tumor progression.


Glaciers Reveal Martian Climate Has Been Recently Active
The prevailing thinking is that Mars is a planet whose active climate has been confined to the distant past. About 3.5 billion years ago, the Red Planet had extensive flowing water and then fell quiet - deadly quiet. It didn't seem the climate had changed much since.


New gene discovered for new form of intellectual disability
The Centre for Addiction and Mental Health (CAMH) has discovered a new form of intellectual disability involving mental retardation (MR) along with the eye defect retinitis pigmentosa (RP).


Study finds that competency in colonoscopy requires experience with 150 cases or more
Researchers from Korea have found that technically efficient screening and diagnostic colonoscopy generally requires experience with 150 cases or more.


MIT-led teams unravel heparin death mystery
An international team of researchers led by MIT has explained how contaminated batches of the blood-thinner heparin were able to slip past traditional safety screens and kill dozens of patients recently in the United States and Germany.


Mitochondrial dysfunction and redox signaling in atrial tachyarrhythmia
Researchers at the University Hospital of Magdeburg (Germany) have discovered that atrial tachycardia is associated with mitochondrial dysfunction and oxidative stress followed by the activation of the NF-kB signalling pathway with induction of NF-kB target gene expression in atrial tissue.


Researchers link master regulator of innate immunity to the hypoxic response
Survival of all animals depends on their ability to withstand microbial infections and adapt to fluctuations in oxygen concentrations.


Researchers discover gene for branchio-oculo-facial syndrome
In a collaborative effort, researchers from Boston University School of Medicine (BUSM) have discovered that deletions or mutations within the TFAP2A gene (Activating Enhancer-Binding Protein) result in the distinctive clefting disorder Branchio-Oculo-Facial syndrome (BOFS).


Domestic violence associated with chronic malnutrition in women and children in India
In a new, large-scale study exploring the link between domestic violence and chronic malnutrition, researchers from the Harvard School of Public Health (HSPH) have found that Indian mothers and children experiencing multiple incidents of domestic violence in the previous year are more likely to be anemic and underweight.


MU psychologists demonstrate simplicity of working memory
A mind is a terrible thing to waste, but humans may have even less to work with than previously thought. University of Missouri researchers found that the average person can keep just three or four things in their "working memory" or conscious mind at one time.


On the High Horse: Why dominant individuals climb the proverbial ladder
In an attempt to grasp complex concepts, humans have tried to represent abstractions like power and dominance through visually-stimulated metaphors such as pyramids and steeples.
