Researchers from the Tulane University School of Medicine have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells. The study, which will be published September 17 in the Journal of Cell Biology, suggests that this act of cannibalism provides these cancer cells with the energy they need to stay alive and initiate tumor relapse after the course of treatment is completed.

CAMBRIDGE, Mass., Sept. 16, 2019 - Despite declining crime rates, tensions between police and the public remain an ongoing issue. High-profile incidents of police violence have led to distrust of the police, particularly among residents in high-crime and low-income areas. While some policymakers promote the use of community-oriented policing (COP) to enhance public trust and police legitimacy, little is known about its actual effectiveness. In a recent study, MIT Sloan Prof. David Rand, in collaboration with Kyle Peyton of Yale University and Prof.

Technological advances are allowing commercial fishing fleets to double their fishing power every 35 years and put even more pressure on dwindling fish stocks, new research has found.

COLUMBUS, Ohio - Eating your tomato sauce with meatballs piled on top could have a surprising downside, new research suggests.

Some of the anti-cancer benefits of tomatoes, specifically those from a compound called lycopene, could disappear when they're eaten with iron-rich foods, according to a new study from The Ohio State University.

NASA's Aqua satellite provided forecasters at the National Hurricane Center with infrared data and cloud top temperature information on Hurricane Kiko. Wind shear was affecting the storm and had closed the eye.

On Monday, September 16, 2019, microwave data and satellite imagery continue to indicate that the core of Kiko is being disrupted. Wind shear from the northeast is preventing Kiko from having a closed eyewall circulation. That means that the storm is subject to outside winds and can weaken.

A Phase III, NRG Oncology clinical trial that compared radiosurgery (SRS) or stereotactic body radiotherapy (SBRT) to the conventional radiotherapy (cEBRT) for patients with spinal metastases indicated that there was no statistically significant difference between the treatments for pain response, adverse events, FACT-G, BPI, and EQ-5D scores. These results were presented during the plenary session of the American Society of Radiation Oncology's (ASTRO) Annual Meeting in September 2019.

DURHAM, N.C.-- Biomedical engineers at Duke University have developed a method to address failures in a promising anti-cancer drug, bringing together tools from genome engineering, protein engineering and biomaterials science to improve the efficacy, accuracy and longevity of certain cancer therapies.

For decades geoscientists have been trying to detect the influence of climate on the formation of rivers, but up to now there has been no systematic evidence.

A new study, led by scientists from the University of Bristol and published today in the journal Nature, discovers a clear climatic signature on rivers globally that challenges existing theories.

Bottom Line: For adolescent girls but not boys, bigger waistlines and greater fat mass were associated with being an evening chronotype who prefers going to bed and waking up later and greater social jet lag because of later sleep timing on weekends versus weekdays, independent of sleep duration and other lifestyle factors. This observational study of 804 adolescents (418 girls and 386 boys; average age 13) from eastern Massachusetts included data from wrist monitors, questionnaires and body measurements.

Lymphomas in the central nervous system are rare but dangerous. Scientists at the German Cancer Research Center (DKFZ) have now discovered which molecular mechanism leads to lymphomas forming metastases in the central nervous system. Using a mouse model, the researchers showed that chronic inflammatory processes in aging brains lead to lymphoma cells that have entered the brain tissue being retained instead of being released directly back into the blood. They also identified key molecules of this mechanism in tissue samples from patients with lymphomas of the central nervous system.

New Haven, Conn. - A key question for climate scientists in recent years has been whether the Atlantic Ocean's main circulation system is slowing down, a development that could have dramatic consequences for Europe and other parts of the Atlantic rim. But a new study suggests help may be on the way from an unexpected source -- the Indian Ocean.

Think of it as ocean-to-ocean altruism in the age of climate change.

The intensity of brain activity during the day, notwithstanding how long we've been awake, appears to increase our need for sleep, according to a new UCL study in zebrafish.

The research, published in Neuron, found a gene that responds to brain activity in order to coordinate the need for sleep. It helps shed new light on how sleep is regulated in the brain.

The conductivity of Graphene has made it a target for many researchers seeking to exploit it to create molecular scale devices and now a research team jointly led by University of Warwick and EMPA have found a way past a frustrating catch 22 issue of stability and reproducibility that meant that graphene based junctions were either mechanically stable or electrically stable but not both at the same time.

A study carried out with a new human stem cell-derived model reveals that the most prevalent genetic risk factor of Alzheimer's disease (AD), apolipoprotein E4 (APOE4), impairs the function of human brain immune cells, microglia. These findings pave the way for new, effective treatment approaches for AD. The results were published in Stem Cell Reports.

For years, astronomers have looked up at the sky and speculated about the strange dimming behavior of Tabby's Star.

First identified more than a century ago, the star dips in brightness over days or weeks before recovering to its previous luminosity. At the same time, the star appears to be slowly losing its luster overall, leaving researchers scratching their heads.

Now, astronomers at Columbia University believe they've developed an explanation for this oddity.
