Taking the measure of legal pot
Researchers detail what we know about consequences for revenue and health — and what we still need to find out

Riskier to know — or not to know — you’re predisposed to a disease?
‘DNA isn’t a crystal ball for every kind of illness’ but potential benefits outweigh fears, says geneticist

A tiny, time-released treatment
Targeted nanotherapy is the wave of the medical future, according to Omid Farokhzad, a Harvard Medical School and Brigham and Women’s Hospital researcher who has two nanoparticle-based therapies in clinical trials and a slew of ideas for new ways to put the tiny capsules to work for human health.

Little improvement seen in antibiotic abuse
Harvard research shows that while only 10 percent of adults with sore throat have strep, the only common cause of sore throat requiring antibiotics, the national antibiotic prescribing rate for adults with sore throat has remained at 60 percent.

Dream saga of WWII
As part of a project by Professor Deirdre Barrett to resurrect a study started in 1940, a group of Harvard undergraduates probed the dreams of British officers captured early in World War II and held in a German prison camp.

Flu’s coming, but which kind?
With a new flu virus appearing in China in April and a new SARS-like respiratory ailment appearing in the Middle East, the Gazette sat down with Harvard epidemiologist Marc Lipsitch to talk about the upcoming flu season.

Deconstructing motor skills
Harvard researchers have found that the brain uses two largely independent neural circuits to learn spatial and temporal aspects of complex motor skills.
-
Narrative of the body, with a nasty twist
Many modern chronic diseases result from mismatches between how our bodies evolved to be used and how we use them today, Harvard evolutionary biologist Daniel Lieberman writes in a new book.
-
Programming genetic code can lead to better designer genes
The key to programming bacteria to follow orders has been found in its protein production. Researchers have learned that by using more rare words, or codons, near the start of a gene, they can remove roadblocks to protein production. The knowledge may mean new drugs and biofuels.
-
A foundation for future research
Harvard researchers recently developed the most detailed “specificity profile” for Cas9 — a “machine” made of protein and RNA that can be programmed to target specific DNA sequences and to precisely cut, paste, and turn on or turn off genes. Future researchers will use the data when developing genetic tools and therapies.
-
Marriage linked to better cancer outcomes
People who are married when diagnosed with cancer live longer than those who are not married. Married patients also tended to have cancers diagnosed at an earlier stage, according to Harvard researchers.
-
Legal remedies
Attorneys, judges, scholars and activists interested in expanding health rights through the law were at the Harvard School of Public Health to discuss progress and challenges.
-
When bacteria fight back
After the U.S. Centers for Disease Control and Prevention issued a report on the threat from drug-resistant bacteria, David Hooper, a physician at Massachusetts General Hospital and an authority on the subject, discussed the issues during a question-and-answer session.
-
40% prevention rate for colorectal cancers
A Harvard study has found that 40 percent of all colorectal cancers might be prevented if people underwent regular colonoscopy screenings. The new research also supports existing guidelines that recommend that people with an average risk of colorectal cancer should have a colonoscopy every 10 years.
-
Recalling a lab-led rescue
Professor Howard Green stumbled across a skin transplant technique that involved growing keratinocytes into full skin layers, making him a pioneer in regenerative medicine.
-
The whys of rising obesity
A panel discussion held by the Forum at Harvard School of Public Health probed the reasons for the modern epidemic of overeating and its particularly harmful effects on children, who are especially susceptible to food marketing.
-
The good life, longer
By synthesizing the data collected in multiple government-sponsored health surveys conducted in recent decades, researchers from the National Bureau of Economic Research, Harvard University, and the University of Massachusetts were able to measure how the quality-adjusted life expectancy of Americans has changed over time.
-
Lifting the ‘family curse’
Removing a woman’s healthy breasts might seem like a radical response to fears of breast cancer. But for women with genetic mutations that put them at high risk of developing the disease, it’s a step that can cut their vulnerability by 90 to 95 percent.
-
Summer in the lab
Students from local high schools spent a chunk of the summer at work in a Harvard lab as part of program co-sponsored by the University’s Life Sciences Education program and the Howard Hughes Medical Institute.

DNA glue directs tiny gel ‘bricks’ to self-assemble
A team of researchers at the Wyss Institute has found a way to self-assemble complex structures out of gel “bricks” smaller than a grain of salt. The new method could help solve one of the major challenges in tissue engineering.
-
Destination space
Jessica Meir, an assistant professor of anesthesia at Harvard Medical School and Massachusetts General Hospital, is the latest member of the Harvard community given a chance to head to space, joining moon-walkers and Hubble Space Telescope repairmen as she trains to become a NASA astronaut.
-
Cancer vaccine begins Phase I clinical trials
A cross-disciplinary team of Harvard scientists, engineers, and clinicians announced Sept. 6 that they have begun a Phase I clinical trial of an implantable vaccine to treat melanoma, the most lethal form of skin cancer.
-
The little old machine that could
In the high-tech laboratory at the Arnold Arboretum’s Weld Hill Research Building, amid an array of expensive, shiny new equipment, sits a 1931 microtome, a machine whose well-oiled parts keep cranking out slices of tissue just 10 micrometers wide, thin enough for light to penetrate and perfect for making slides to see the internal cellular structure of plants.
-
Lasering in on tumors
In the battle against brain cancer, doctors now have a new weapon: an imaging technology that will make brain surgery dramatically more accurate by allowing surgeons to distinguish between brain tissue and tumors, and at a microscopic level.
-
Skip the juice, go for whole fruit
Harvard researchers have found that people who ate at least two servings each week of certain whole fruits — particularly blueberries, grapes, and apples — reduced their risk for type 2 diabetes by as much as 23 percent in comparison to those who ate less than one serving per month.
-
Organs-on-chips evaluate therapies for lethal radiation exposure
A team at the Wyss Institute at Harvard has received a $5.6 million grant from the FDA to use its organs-on-chips technology to test human physiological responses to radiation and evaluate drugs designed to counter those effects.
-
A marker for breast cancer
An international scientific collaborative led by the Harvard Stem Cell Institute’s Kornelia Polyak has discovered why women who give birth in their early 20s are less likely to develop breast cancer than women who don’t, triggering a search for a way to confer this protective state on all women.

A cross-country collaboration
Amy Wagers and Emmanuelle Passegué have found that cancer stem cells actively remodel the environment of bone marrow, where blood cells are formed, so that it is hospitable only to diseased cells. This finding could influence the effectiveness of bone marrow transplants.
