A dream solution to cancer metastasis has been to develop a method that can track and kill the cancer cells that are on the move. The complexity at which those cancer cells operate has long been a formidable obstacle to stopping metastases, which cause 90 percent of cancer deaths, but that may change.

Stem cells demonstrate a bizarre property never before seen at a cellular level, according to a new study. The property– known as auxeticity– is one which may have application as wide-ranging as soundproofing, super-absorbent sponges and bulletproof vests.
Although doctors have long known that people with Down syndrome have a heightened risk of developing acute lymphoblastic leukemia (ALL) during childhood, they haven’t been able to explain why. Now, a team investigators has uncovered a connection between the two conditions.
Cloning has finally generated immunologically compatible embryonic stem cells for older humans: two men aged 35 and 75. It may also generate significantly fewer tumor-causing mutations than the popular induced pluripotent stem cell (iPSC) method of making ES cells.
Researchers have sequenced the entire genome and all the RNA products of the most important pathogenic lineage of Cryptococcus neoformans, a strain called H99.
Researchers have discovered an unexpected phenomenon in the organs that produce sperm in fruit flies: when a certain kind of stem cell is killed off experimentally, another group of non-stem cells can come out of retirement to replace them.
Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
Pall introduced a 13 mm Acrodisc MS syringe filter certified for low extractables in high performance liquid chromatography/mass spectrometry (LCMS) applications. The new 13 mm size, which is designed specifically for small sample analysis using LCMS, complements Pall’s current Acrodisc MS syringe filter offering of a 25 mm filter.
Depression can hit young fathers hard- with symptoms increasing dramatically during some of the most important years of their children’s lives, a new study has found.
Patience may be a virtue. But in a lab that’s bustling with scientists conducting meaningful biological research, excessive waiting can be downright frustrating. Such was the case leading up to 2012, when researchers at The University of Chicago Flow Cytometry Core Facility— known as UCFlow— would routinely wait as long as 16 days to be able to sort cells.
The more cups of coffee a person drank, the lower the risk for developing hepatocellular carcinoma (HCC), the most common type of liver cancer, according to new research.
Researchers have succeeded in developing a method fast enough to observe immediate changes in the function of the brain even when watching a movie. When we watch a movie, our brains react to it immediately in a way similar to other people's brains.
In a new study, researchers solved an age-old mystery of touch: how cells just beneath the skin surface enable us to feel fine details and textures.
NuAire’s Glacier -86 C Ultralow Temperature Freezers’ energy efficient cascade cooling system monitors temperature and pressures throughout high and low stage circuits. The inner chamber is surrounded by foam-in-place polyurethane insulation.
Riken Institute brass want co-authors of the “acid bath” stem cell papers to retract one, after appeal, citing deliberate misconduct. But two developments may complicate this. First, lead author Haruko Obokata refuses to accept it. And Kenneth Lee has become the first scientist outside the co-authors to publicly claim that, following the latest protocol for acid bath cells, he may have made them.
Brooks BioStore II has fully redundant refrigeration circuits that provide reliability as well as additional cooling capacity under unusual heat load conditions. The system may also use liquid nitrogen as a backup refrigerant in case of power failure.
Cloning pioneer Teru Wakayama found two STAP stem cell batches made for recent Nature STAP papers were apparently not derived from a 129 mouse strain, as he was told, but F1 and B6 strains. While the erroneous data, which appeared in one of the papers, does not affect the works' main thrust, it is spurring calls for reviews of other STAP stem cell sources.
Nature has rejected the paper of a top Hong Kong researcher whose lab several times failed to replicate results of the now-famous “acid bath” stem cell papers. That researcher is now trying to reproduce the work as it appears in yet another new updated protocol, posted Thursday by Harvard researchers. Meanwhile, in interviews, Harvard's Vacanti clarifies some mysteries.
Archaeologists have found the oldest complete example in the world of a human with metastatic cancer in a 3,000 year-old skeleton. The skeleton of the young adult male was found by a Durham University PhD student in a tomb in modern Sudan in 2013 and dates back to 1200BC.
Harvard's Charles Vacanti will post tips to make "acid bath" stem cells as early as today. This, even as "acid bath" lead author Haruko Obokata said she plans to withdraw her 2011 thesis. And four of 14 co-authors of "acid bath" papers—along with some coauthors’ boss— want them retracted. Yet that same boss signaled confidence in the papers' premise. “Almost too amazing,” says CIRM's recent chief.
CORTECS Columns from Waters Corporation are new 1.6 micron solid-core UltraPerformance LC Columns that set a new standard in LC column performance. The higher efficiency brought with the columns allows laboratories to produce greater amounts of information faster with every chromatographic separation.
Ten projects that will enable non-government researchers to conduct clinical research at the National Institutes of Health’s Clinical Center in Bethesda, Md. were announced. Through these three-year, renewable awards of up to $500,000 per year, scientists from institutions across the United States will collaborate with government scientists in a highly specialized hospital setting.
Through memory loss, unnecessary information in the brain is deleted and the nervous system retains its plasticity. Previously, it was not clear if this process was active or passive, but scientists have now discovered a molecular mechanism that actively regulates the process of forgetting.
At least two camps have formed in the “breast cancer stem cell” world. One camp believes most cancers may come from stem cells—or stem-like progenitors—gone awry. Others agree cancers can be most virulent when reaching a stem cell-like state—but believe they may come from both stem cells and mature cells gone awry.
In a new study that could help doctors extend the lives of patients awaiting liver transplants, a Rice University-led team of researchers examined the metabolic breakdown that takes place in liver cells during late-stage cirrhosis and found clues that suggest new treatments to delay liver failure.
Veterans exposed to explosions who do not report symptoms of traumatic brain injury (TBI) may still have damage to the brain's white matter comparable to veterans with TBI, according to researchers at Duke Medicine and the U.S. Department of Veterans Affairs. The findings suggest that a lack of clear TBI symptoms following an explosion may not accurately reflect the extent of brain injury.
