Breathing easier with combinations
 

The first drug to target the most common genetic defect of cystic fibrosis was approved in July 2015 by the US Food and Drug Administration (FDA). The new drug, Vertex’s Orkambi, can treat as many as half of cystic fibrosis patients. Orkambi combines Vertex’s first approved cystic fibrosis drug, Kalydeco (ivacaftor), with a second small molecule, lumacaftor. This first approved combination therapy will open up an increasing proportion of patients for treatment. But companies are banking on even more efficacious combinations.

Gene therapy ‘cure’ for blindness wanes 
Two independent groups recently reported  long-term results for a gene therapy of Leber’s congenital amaurosis (LCA), a rare form of inherited childhood blindness. Both trials, testing a single eye in each patient, found that efficacy diminished after three or more years, sounding a cautious note amid the technology’s rapturous renaissance Nature Biotechnology 820 words ARTICLE 

Tracing Ebola’s Evolution
The ongoing Ebola outbreak is the largest on record. The World Health Organization (WHO) this week (June 17) reported 27,305 confirmed cases, including 11,169 deaths. In an effort to better understand the deadly virus, scientists have mapped the transmission and evolution of Ebola at the epicenter of the 2014 epidemic (Guinea, Liberia, and Sierra Leone), providing a detailed look at the virus throughout the first nine months of the outbreak. Together with previously published Ebola sequencing analyses, the results of two independent studies published this week could help health officials better prepare for and control future outbreaks.

Industry chases pan-genotypic and shorter HCV treatments
The dramatic success enjoyed by Gilead Sovaldi (sofosbuvir) and more recently Harvoni (ledipasvir and sofosbuvir) have left few gaps in the HCV market. But a pan-genotypic treatment could simplify the treatment options, now a dizzying array of combination genotype matches, and, if the biotech giant has its way, shorten treatment considerably from the current 12 weeks.

Resistance Fighter
Stuart Levy has spent a lifetime studying mechanisms of antibiotic resistance and crusading to abolish the use of antibiotics in animal feed.  Here, Levy talks about the prank he and his twin brother (Jay Levy, who was among the first to discover the HIV virus) executed that earned them a brief spot in the limelight; how science allowed him to travel the world—and befriend Samuel Beckett; and an urgent call to a castle in Prague about chicken eggs. The Scientist 2500 Words ARTICLE

Brain Teaser
Autism is thought to arise from a combination of factors, some genetic and others the result of environmental issues such as the mother’s health during pregnancy, parental age, and exposure to pollutants. New research indicates that mouse pups born to mothers who had the flu during pregnancy show characteristics of autism and exhibit brain changes. So far, the work suggests that the link to autism likely is not the flu itself, but the response of the mother’s immune system. Princeton Alumni Weekly 500 words ARTICLE

First-in-class HIV drug enters phase 3 trials
New York–based Bristol-Myers Squibb (BMS) has moved a first-in-class HIV attachment inhibitor into phase 3 testing, after announcing positive results from a 48-week phase 2b study in February. BMS-663068 is the first drug to target the protein gp120 on the viral envelope to prevent initial attachment to the CD4 receptor. Because this small molecule works through a novel mechanism and targets a highly conserved area of the virus, it could be particularly useful in people with resistant HIV who have had many other treatments. Nature Biotechnology 680 words ARTICLE

Targeting Antibiotic-Resistant Bacteria with CRISPR and Phages
Using bacteriophages to deliver a specific CRISPR/Cas system into antibiotic-resistant bacteria can sensitize the microbes to the drugs, according to a study published in PNAS. The approach, developed by Udi Qimron of Tel Aviv University and his colleagues, is a modified version of phage therapy that does not require the delivery of phages to infected tissues and could help offset the pressure on bacterial populations to evolve drug resistance, according to the team. The Scientist 850 words ARTICLE

Gut Microbes Influence Circadian Clock 
The mammalian gut microbiome is involved in controlling the circadian rhythm of its host, according to a mouse study published in Cell Host & Microbe. In both mice and humans, timing of feeding and diet type can impact the bacterial populations of the gut. Now, Eugene Chang of the University of Chicago Medical Center and his colleagues have found that mouse gut microbiota produce metabolites in diurnal patterns, and these can influence the expression of circadian clock genes in the liver. The Scientist 850 words ARTICLE

Brain’s Role in Browning White Fat 
Tver since energy-storing white fat has been shown to convert to metabolically active beige fat, through a process called browning, scientists have been trying to understand how this switch occurs. The immune system has been shown to contribute to activation of brown fat cells. Now, researchers from Monash University in Australia and their colleagues have shown that insulin and leptin—two hormones that regulate glucose metabolism and satiety and hunger cues—activate “satiety” neurons in the mouse hypothalamus to promote the conversion of white fat to brown. The results are published today (January 15) in Cell. The Scientist 850 words ARTICLE

New Antibiotic from Soil Bacteria  
Many of the most widely used antibiotics have come out of the dirt. Penicillin came from Penicillium, a fungus found in soil, and vancomycin came from a bacterium found in dirt. Now, researchers from Northeastern University and NovoBiotic Pharmaceuticals and their colleagues have identified a new Gram-positive bacteria-targeting antibiotic from a soil sample collected in Maine that can kill species including methicillin-resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis. Moreover, the researchers have not yet found any bacteria that are resistant to the antibiotic, called teixobactin. Their results are published in Nature.The Scientist 850 words ARTICLE

Stem Cell Divisions Help Explain Cancer Risk

Mind Games: The Truth About Brain-Fitness Programs 
An investigative report on the brain fitness companies that claim their on-line brain games will improve your daily life by sharpening your cognitive skills, including memory, mental speed, task switching, and verbal fluency. However, experts say that increasing your brain-fitness score doesn’t do much beyond improving your game-playing ability. Consumers Digest 2400 words ARTICLE

Reprogramming Redux  
The stem cell field was rocked earlier this year by investigations into researchers’ claims to have reprogrammed somatic cells into pluripotent progenitors without the aid of transcription factors, which—given several failed attempts at independent replication, among other things—eventually led to the retraction of two Nature studies. So it was somewhat of a surprise when last month, another team claimed to have reprogrammed somatic cells toward a stem-like state by manipulating mechanical forces alone.

All Systems Go 
Alan Aderem earned his PhD while under house arrest for protesting apartheid in South Africa. His early political involvement has guided his scientific focus, encouraging fellow systems biologists to study immunology and infectious diseases. Aderem discusses how exile from South Africa led him to study diseases such as malaria, tuberculosis, and HIV; why all of his experiments in graduate school were on the millisecond time scale; and how he helped launch the world’s first systems-biology institute. The Scientist 2500 words ARTICLE

New Stem Cell State
Researchers have uncovered a new type of pluripotent mouse stem cell—the “F-class” cell—through use of a somatic cell reprogramming approach. An F-class cell is able to differentiate into all three embryonic precursor tissues, yet is phenotypically and molecularly different from previously characterized induced pluripotent stem cells (iPSCs) made from somatic cells. The Scientist 850 words ARTICLE

Brains in Action 
An inspiring lecturer turned Marcus Raichle’s focus from music and history to science. Since then, he has pioneered the use of imaging to study how our brains function.

Supporting the “Good” Gut Microbes 
Mice with systemic bacterial infections induce a pathway that makes a sugar called fucose readily available to feed the beneficial microbiota in the small intestine, according to a study published today (October 1) in Nature. This newly uncovered protective mechanism helps maintain the “good” bacterial populations in the gut while the animal is sick—and appears to protect against further infections. The Scientist 900 words ARTICLE

Cities Launch Global Alliance to Lower Carbon Emissions 
More than 2,000 cities have banded together in what the UN calls the largest effort by cities so far to curb their greenhouse gas emissions. The goal of the Compact of Mayors is to reduce greenhouse gas emissions by 454 million tonnes a year by 2020 — equivalent to the carbon dioxide emissions from 130 coal power plants — through knowledge sharing and transparent and accountable measures. SciDev.Net 400 words ARTICLE

Identifying Cancer Mutations as Therapeutic Targets 
Cancer therapies are increasingly targeting specific molecular pathways and mutations. Molecular testing to identify a mutation expressed in a tumor is becoming common both in clinical research and to gauge whether a patient is eligible for a Food and Drug Administration–approved therapy. These molecular testing efforts have focused on well-defined pathways that drive tumor growth. And yet researchers are just beginning to understand the genes and pathways important for progression of various tumor types. Journal of the National Cancer Institute 1800 words ARTICLE

Sugar Substitutes, Gut Bacteria, and Glucose Intolerance 
Non-caloric sweeteners can spur glucose intolerance in mice and some people, according to a study published in Nature. Researchers from the Weizmann Institute of Science in Israel and their colleagues have uncovered that artificial sweeteners can drive changes in the gut microbiota that then promote glucose intolerance. Immunologist Eran Elinav and computational biologist Eran Segal, both of the Weizmann Institute, identified changes in the composition and function of the mouse gut microbiome after the animals consumed artificial sweeteners—changes similar to those previously linked to obesity and diabetes in humans, the authors noted. Two small human studies also support these fundings. The Scientist 900 words ARTICLE

Next Generation: Blood-Cleansing Device 
A microfluidic device filled with magnetic nanometer-sized beads that bind a plethora of pathogens and toxins was able to clear these invaders from the blood of rats with sepsis, improving their outcomes, according to a paper published today (September 14) in Nature Medicine. The design of the extracorporeal device was inspired by the small vessels and sinusoids within the spleen, through which blood “trickles slowly, almost like in a wetlands, efficiently capturing pathogens” said lead study author Donald Ingber, a professor at Harvard Medical School and founding director of the Wyss Institute in Boston. The Scientist 800 words ARTICLE

Brain Genetics Paper Retracted
The authors of a June PNAS paper that purported to identify sets of genes associated with a specific brain function last week (August 29) retracted the work because of flaws in their statistical analyses. “We feel that the presented findings are not currently sufficiently robust to provide definitive support for the conclusions of our paper, and that an extensive reanalysis of the data is required,” the authors wrote in their retraction notice. The Scientist 800 words ARTICLE

Crossing Boundaries 
In the early 1980s, Pascale Cossart was a researcher at the Institut Pasteur, working on the interaction of E. coli proteins with DNA, when the Pasteur’s scientific director encouraged her to switch to the study of infectious diseases so as not to have to compete with bigger laboratories working on E. coli in the U.S. A biochemist with no biology training, Cossart chose to work on the food-borne bacterium Listeria monocytogenes, a little-studied and intriguing intracellular pathogen that can have serious consequences if it infects a pregnant woman or travels to the brain. Those with a compromised immune system are particularly at risk from complications of a Listeria infection.“ This was a time when researchers were only just beginning to use molecular biology to study organisms other than E. coli,” says Cossart. The Scientist 2400 words ARTICLE

When the Neanderthals Disappeared 
Neanderthals overlapped with early modern humans and, based on genetic evidence, even interbred. But the extent of the overlap of the two species both in terms of time and geography is still not fully known, mainly because it has been difficult to accurately date archaeological specimens that go back more than 30,000 years. Using newer techniques, a large-scale dating effort of Neanderthal specimens from Western Europe to Russia now narrows the timing of the extinction of Neanderthals to a span of 2,000 years—between 39,000 and 41,000 years ago. The study is published in Nature. The Scientist 800 words ARTICLE

Cancer Prognosis: Role of BMI and Fat Tissue 
Data are emerging that individuals with advanced cancers—and other acute or chronic diseases—may have advantage against poorer outcomes if they have a higher body mass index (BMI). That obesity increases risk of acute and chronic disease diagnosis but protects individuals against worse outcomes once diagnosed is the so-called obesity paradox. But how best to explain this observation is far from clear. JNCI 1800 words  ARTICLE

Connecting the Dots
Entomologist, and evolutionary and theoretical biologist, Mary Jane West-Eberhard started out by studying the behaviors of  social wasps, first in Michigan and then in Central America. She spent her career probing the evolutionary relationship between social behavior and developmental flexibility–making many connections others may not notice. The Scientist 2085 words ARTICLE

Markers Distinguish “Good” from “Bad” Fat
Since the discovery that not all fat cells are created equal, there has been a search for ways to reliably identify the so-called “good,” metabolically active, brown adipocytes, and the “bad,” relatively inert, white adipocytes. Thus far, biomarkers to distinguish brown from white fat have all been either intracellular or secreted proteins, which are not useful for whole-tissue or in vivo studies. Now, researchers have identified three cell-surface markers specific to adipocytes that are differentially expressed on white, brown, or third form of fat cell—beige—in both mice and in human tissue. The Scientist 800 words ARTICLE

Neurodegeneration and Protein Translation Linked
Searching for new mutations associated with neurodegenerative and cognitive defects, researchers have uncovered two mouse genes that function in the same critical pathway such that, when both are lost, neurodegeneration results. The genes are both involved in protein translation and, surprisingly, one encodes a transfer RNA (tRNA) gene uniquely expressed in the brain—a first example of such differential expression in vertebrates. The Scientist 820 words ARTICLE

Added Layers of Proteome Complexity
There may be more to the human proteome than previously thought. Some genes are known to have several different alternatively spliced protein variants, but the Scripps Research Institute’s Paul Schimmel and his colleagues have now uncovered a broad spectrum–almost 250 protein splice variants–of an essential, evolutionarily conserved, and well-studied family of human genes. The Scientist 750 words ARTICLE

Gestational Malnutrition Affects Offspring’s Sperm
The effects of malnutrition in the late stages of a female mouse’s pregnancy can produce epigenetic changes in the sperm of her male offspring.

Rewriting History 
Yael Niv, an assistant professor of psychology and neuroscience, is teasing out how our brains learn from experience and how we can unlearn fears and habits. The research has important implications for those with post-traumatic stress disorder. “We want to understand how an old, possibly traumatic memory can be erased,” she explains. The key, according to Niv, is understanding when the brain forms new memories and when it updates old ones. Princeton Alumni Weekly 500 words ARTICLE

Not All Stem Cells Created Equal
In the process of converting a somatic cell to a stem cell, researchers have questioned whether the resulting cells retain characteristics of their prior, non-stem-cell states. Applying two pioneering approaches to create human pluripotent stem cells from somatic cells—by inducing pluripotent stem cells (iPSCs) or using a process called somatic cell nuclear transfer (SCNT)—researchers from Oregon Health & Science University (OHSU) and their colleagues have compared the genomic and epigenomic landscapes of the resulting cell types. The Scientist 900 words ARTICLE

Light-Sensing Retina in a Dish
Researchers have taken another step toward creating a functional human retina in the laboratory. Previous studies showed that an early-stage retina, including photoreceptors with primary cilia and parts of the inner segment structure, can be generated in culture from induced human pluripotent stem cells (iPSCs). Now, Maria Valeria Canto-Soler, director of the retinal degeneration research center at Johns Hopkins University and her colleagues demonstrate the ability to grow the most mature retinal tissue from iPSCs yet: the in vitro product was able to develop functional photoreceptor cells. The Scientist 790 words ARTICLE

Female Pigs May Sense Sex of Sperm 
A new study suggests that female mammals may be able to sense and respond differently to X and Y chromosome sperm. Researchers show that in the presence of either predominantly X or Y sperm populations, the oviducts of pigs respond differently—by increasing or decreasing the expression of various genes. According to the study authors, this is the first evidence that the female can somehow tell the difference between X and Y chromosome sperm prior to fertilization and activate signaling pathways in a sex-specific way.The Scientist 720 words ARTICLE

Ancient Skeleton Sheds Light on Native American Roots
The uncovering of an almost completely intact, 12,000-year-old skeleton of a 15- or 16-year-old girl—found in an underwater cave near Mexico—lends support to the idea that modern Native Americans originated from an ancient population that came from Beringia, not from distinct migrations of peoples from different parts of Asia and Europe. The discovery of this remarkably well-preserved specimen by divers has, for the first time, allowed researchers to perform both genetic and morphological analyses from a single, ancient individual. The Scientist 760 words ARTICLE

Mystery around drug adherence still plagues medical literature 
The randomized controlled trial, or RCT, represents the gold standard of interventional studies of new drugs. But how reliable are the results when it remains unknown whether subjects in the trial actually took their medicines at all? A 2007 analysis found that only 33% of 192 papers describing RCTs of oral therapies for six chronic diseases disclosed adherence results (Am. J. Med. Sci. 334, 248–254, 2007). Now, in light of new data suggesting a continued lack of information about drug adherence in the medical literature, some researchers are calling for a reform of reporting guidelines. Nature Medicine 680 words ARTICLE

Fuel Gauge
Human brain cells use about one-fifth of the body’s energy. Scientists assume that neurons are energy hogs, but know little about how they manage those energy demands, says Timothy Ryan, a biochemist and neuroscientist at Weill Cornell Medical College. The energy needs of presynaptic nerve terminals must be addressed locally, as the synapse can be as far away as one meter from the cell body. Together with colleagues, Ryan has engineered an optical reporter system called Syn-ATP that, when expressed in neurons, can directly measure the number of ATP molecules specifically located at presynaptic nerve terminals.

Inactive Actin
For decades, scientists observed clathrin-mediated endocytosis (CME)—the process of forming vesicles to pull protein cargo into a cell—ceasing during mitosis in mammalian cells. But they didn’t know why. From prophase to anaphase, shallow clathrin-coated pits form at the plasma membrane, but the cell never internalizes them. A new study shows that endocytosis shuts down during mitosis in eukaryotic cells because all of the required actin is hoarded by the cytoskeleton. The Scientist 500 words ARTICLE

Cancer Risk: The Fat Tissue–BMI–Obesity Connection
Released in February, the International Agency for Research on Cancer’s World Cancer Report 2014 predicted that in the next 20 years, new cancer cases will increase by about 57% each year, from 14 million to 22 million. Many of these cancers are linked to lifestyle choices, such as tobacco and alcohol use, eating processed foods, and low levels of physical activity, the report said. Studies are also showing that the risk of being diagnosed with esophageal, colon, pancreatic, endometrial, kidney, and postmenopausal breast cancers is higher in people with excess body fat. The Journal of the National Cancer Institute 1600 words ARTICLE

Antibiotic Resistance: Invasion of the Superbugs 
The stubborn problem of drug-resistant bacterial diseases is escalating. Over the last several decades, the number of drug-resistant strains of diseases has been growing. Each year more than 2 million people in the United States are infected with “superbugs” that have developed resistance to most antibiotics, according to the Centers for Disease Control and Prevention (CDC), and 23,000 of them die. Princeton researchers and scientists are working on better understanding how antibiotic resistance and works, how government policies can help to combat the problem, and novel antibiotic approaches to tackle antibiotic resistance, one bug at a time.

Protein Protects Aging Brain 
A long-standing question in neurology is why some elderly people develop dementia and others do not. Researchers are also left to wonder why some people have Alzheimer’s disease-like brain pathology yet show no cognitive symptoms. A study published in Nature provides new clues that could help solve both puzzles, showing that a previously unknown stress response kicks in later in life to protect aging neurons. Researchers at Harvard Medical School found that a protein called REST, which is well characterized as a transcription factor that represses neuron-specific genes during embryogenesis, is switched on during middle- and late-adulthood, helping to protect neurons of the hippocampus and cortex from oxidative stress and the aggregated and misfolded proteins characteristic of Alzheimer’s and other neurodegenerative diseases. The Scientist 850 words ARTICLE

Will Your Thoughts Always Be Private? Q&A with Joshua Greene,  the director of the Moral Cognition Lab at Harvard University 
Joshua Greene *02, uses fMRI — functional magnetic resonance imaging — to study how our brains make decisions. The technology “detects the concentration of oxygenated versus de-oxygenated blood, so you can see where oxygen is being used in the brain,” a proxy for the activity of neurons, he explains. That gives scientists a way to see what is taking place in the brain when someone is making decisions — assuming that person happens to be inside an fMRI machine at the time. I spoke with him about the technology’s potential and shortcomings: Are we approaching a time when we cannot guard even our thoughts? Princeton Alumni Weekly 1300 words ARTICLE

Concerned About HPV-Related Cancer Rise, Researchers Advocate Boosting HPV Vaccination Rates 
Deaths from the major cancers—lung, colorectal, breast, and prostate—continue to decline, a trend that started in the early 1990s. Cancer incidence is also declining, if slightly, for both sexes. That’s the good news. But researchers are also tracking an uptick in rates of anal and oropharyngeal cancer, a type of head and neck cancer related to infection with the human papillomavirus (HPV), in the 10-year period ending in 2009. Cancer of the oropharynx increased among white men and women (3.9% and 1.7%, respectively). Anal cancer also increased in both sexes, with the greatest increase among black men (5.6%) and white women (3.7%). Rates of vulvar cancer, another HPV-related cancer, also increased among women despite continued lower rates of cervical cancer. Researchers attribute this rise in HPV-related cancers to more HPV infections. Journal of the National Cancer Institute 1,400 words ARTICLE

Supreme Court Ruling Broadens BRCA Testing Options 
The predictive genetic test that screens for mutations in both BRCA genes has been available only through Utah-based Myriad Genetics, a molecular diagnostics company that holds patents on the BRCA genes. But the Supreme Court has lifted what was a monopoly on BRCA genetic testing, invalidating five of Myriad’s BRCA patents. In a unanimous ruling on June 13, the high court deemed isolated genes natural phenomena that companies may not patent. Still, both plaintiffs and defendants announced that the ruling was in their favor.

Thomas Gregor: Biological Quantifier 
Those who want to study living systems generally major in biology. But Thomas Gregor’s path first took him through math and physics. Only after completing a master’s degree in theoretical physics at the University of Geneva did Gregor return to his core interest: understanding the fundamentals of how life works. The Scientist 500 words ARTICLE

Gravity plays a role in keeping cells small 
The effects of gravity are relevant when building houses or flying airplanes, but biologists have generally accepted that the average cell is too small for gravity to play a role in how it is built or behaves. A finding by Princeton University researchers now shows gravity imposes a size constraint on cells. The results provide a novel reason why most animal cells are small and of similar size.  Princeton University Homepage 900 words ARTICLE

Some Respect, Please, for the Glorious Drosophila 
If you’re one of those people who runs for a can of Raid after finding a swarm of fruit flies hovering over the ripe bananas in your kitchen, consider this: For more than a century, scientists have come to understand some of the most important processes taking place in the human body by studying these flies. Princeton Alumni Weekly 1,000 words ARTICLE

They Rely on the Fly Much of the progress in medicine and human health has resulted from basic science and the search to understand life at a fundamental level: how normal cells function, how genes are expressed, and how cells communicate with one another. These professors, among others, use Drosophila melanogaster in this work.

Loved in the Lab The fruit fly has competition when it comes to popularity. Descriptions of three others on researchers’ hot lists.

BREAKING GROUND: The Physics of Cancer Cells 
In 2009, physics professor Robert Austin received a call from the National Cancer Institute, asking him to take part in a new program that aimed to study the physical principles of cancer. The idea was to develop outside-the-box approaches to cancer research by bringing together chemists, mathematicians, engineers, and physicists: “weird guys who are working on strange things” who might provide insight into the disease, Austin said.

Supreme Court Ruling Invalidates Myriad’s BRCA Gene Patents 
The Supreme Court announced a unanimous 9–0 decision that genes cannot be patented. After a long legal battle, the high court ruled in favor of the plaintiffs—the American Civil Liberties Union (ACLU) and the Association for Molecular Pathology (AMP)—declaring that genes are indeed products of nature and cannot be treated as inventions. The ACLU, along with scientists, clinicians, and patient advocates, had challenged the patents of Utah-based Myriad Genetics on two of the breast cancer susceptibility genes, BRCA1 and BRCA2. The patents on these genes allowed Myriad to have a monopoly on BRCA genetic testing, which is important for women to understand their risk of breast and ovarian cancers. CancerNetwork 675 words ARTICLE

The Promise of Circulating Tumor Cells 
Circulating tumor cells (CTCs)—cells shed from a tumor into the bloodstream as the tumor develops—were first identified in the early 1860s. Although the use of CTCs as a “liquid biopsy” to detect and monitor tumor growth has long been a goal, developing the technology for detecting and analyzing CTCs has been a challenge. Recent advances, however, have moved the field forward, bringing the analysis of CTCs in oncology patient care one step closer to reality. The International Journal of Targeted Therapies in Cancer 670 words ARTICLE

BREAKING GROUND: Opening the Way to Hydrogen Fuel

BREAKING GROUND: Bringing Back the Lions and Zebras 
Gorongosa National Park in Mozambique was once one of the world’s most diverse ecosystems. Its 1,525 square miles supported populations of elephants, antelopes, zebras, buffalo, and lions, making it among the most densely populated large-mammal areas in Africa. Then 16 years of civil war, starting in 1977, devastated the park. Robert Pringle, assistant professor of ecology and evolutionary biology at Princeton is seizing an unusual opportunity to observe the repopulation of large mammals and other animals after their near-extinction–and helping conservation efforts. Princeton Alumni Weekly 500 words ARTICLE

BREAKING GROUND: Pursuing a link to aging, cancer 
Because telomeres shorten as a cell ages, telomeres of an older person generally are much shorter than those of someone young. But an enzyme called telomerase can add extra DNA repeats onto the telomeres, and thus can lengthen the shorter telomeres every time a cell divides.How this happens is one of the questions of the laboratory of ­Virginia Zakian, professor of molecular biologyPrinceton Alumni Weekly 500 words ARTICLE
