Durham, NC - A study released today in STEM CELLS Translational Medicine offers hope for those suffering from a chronic, difficult to treat condition called non-tuberculous mycobacteria (NTM) lung infection. The study describes how researchers at Case Western University developed a new model of NTM lung infection and then used it to show how effective human mesenchymal stem cells (hMSCs) are in treating this condition - and even which donor cells might be best for doing so.
Osaka, Japan —Straight-line constant-speed propagation in free space is a basic characteristic of light. In a recent study published in Communications Physics, researchers from Osaka University discovered the phenomenon of reciprocating propagation of laser pulse intensity in free space.
Cancer of the colon and rectum is one of the deadliest forms of cancer, and has in recent years affected growing numbers of young people. In the largest registry study to date, researchers at Karolinska Institutet in Sweden and Harvard University in the USA demonstrate a possible connection between colorectal polyps in close relatives and the risk of developing colorectal cancer. The study, which is published in the British Medical Journal, is of potential consequence for different countries' screening procedures.
PULLMAN, Wash. -- Professor Arda Gozen looks to a future someday in which doctors can hit a button to print out a scaffold on their 3-D printers and create custom-made replacement skin, cartilage, or other tissue for their patients.
Dating violence - physical, sexual, psychological or emotional within a relationship, including stalking - is pervasive on college campuses with far-reaching health implications. One in five women experience a sexual assault in college and students living in sorority houses are three times more likely to experience rape. College students are vulnerable to dating violence because of the influence of their social and living environments.
Aging is the biggest risk factor for perturbation of the nervous system, even in the absence of distinct disease or trauma. For yet unknown reasons, the impulse conducting, myelinated projections and synaptic connections between nerve cells are especially vulnerable to aging-related degeneration. These pathological alterations often manifest as cognitive, sensory, and motor decline in older adults and represent a serious socio-economic challenge.
Malactivation leads to damage
Abu Dhabi, UAE, May 3, 2021: Researchers from NYU Abu Dhabi's Center for Genomics and Systems Biology have successfully sequenced the genome of previously extinct date palm varieties that lived more than 2,000 years ago. They did so using date palm seeds that were recovered from archaeological sites in the southern Levant region and radiocarbon-dated from the 4th century BCE to the 2nd century CE. The seeds were germinated to yield viable, new plants.

BURLINGTON, VT -- In the aftermath of George Floyd's 2020 murder by former police officer Derek Chauvin, many families may find themselves actively engaging in--or uncomfortably fumbling around--discussions about race. For white parents looking to clearly communicate antiracist ideologies with their preadolescent children, a new study offers some insight.
Talking about your bad day at work could lead to great solutions. Cold Spring Harbor Laboratory (CSHL) Associate Professor Saket Navlakha and his wife, Dr. Sejal Morjaria, an infectious disease physician at Memorial Sloan Kettering Cancer Center (MSK), found a way to predict COVID-19 severity in cancer patients. The computational tool they developed prevents unnecessary expensive testing and improves patient care.
Morjaria says, "Generally, I have good intuition for how patients will progress." However, that intuition failed her when confronted with COVID-19. She says:
A Wyss Institute-led collaboration spanning four research labs and hundreds of miles has used the Institute's organ-on-a-chip (Organ Chip) technology to identify the antimalarial drug amodiaquine as a potent inhibitor of infection with SARS-CoV-2, the virus that causes COVID-19.
A grass commonly used to fight soil erosion has been genetically modified to successfully remove toxic chemicals left in the ground from munitions that are dangerous to human health, new research shows.
The study - led by the University of York- demonstrates that genetically modified switchgrass (Panicum virgatum) can detoxify residues of the military explosive, RDX, left behind on live-fire training ranges, munitions dumps and minefields.
A research team led by City University of Hong Kong (CityU) scientists recently developed a new generation of microneedles technology which allows the intradermal delivery of living cells in a minimally invasive manner. Their experiment showed that vaccination using therapeutic cells through this ground-breaking technology elicited robust immune responses against tumours in mice, paving the way for developing an easy-to-use cell therapy and other therapeutics against cancers and other diseases.
