EMBARGOED: Dana-Farber investigators pinpoint keys to cell therapy response for leukemia
2025-01-24
Boston – Dana-Farber Cancer Institute researchers have identified factors that determine whether donor lymphocyte infusion (DLI), a standard therapy for patients with acute myeloid leukemia (AML) who have relapsed after allogenic hematopoietic stem cell transplant, will successfully move the patient into remission. The team identified that a key cell type in the DLI product and features of the tumor microenvironment in patients both play a role.
The findings were published in Science Immunology.
“Relapse of AML after stem cell transplant is a major challenge,” says first author Katie ...
Surgeon preference factors into survival outcomes analyses for multi- and single-arterial bypass grafting
2025-01-24
LOS ANGELES—January 24, 2025—In patients undergoing coronary artery bypass grafting (CABG), a novel analysis evaluating surgeon preference for multi- versus single-arterial grafting may help explain the differing results between prior retrospective analyses and randomized controlled trials regarding long-term survival.
A study presented this week at The Society of Thoracic Surgeons’ 61st Annual Meeting explores findings in more than a million U.S. Medicare beneficiaries who underwent CABG from 2001 to 2019. The researchers found that patients who received multi-arterial grafting (MAG) had improved survival over those who ...
Study points to South America – not Mexico – as birthplace of Irish potato famine pathogen
2025-01-24
Call it a mystery solved.
North Carolina State University researchers firmly point the finger at the South American Andes Mountains as the place where the Irish potato famine pathogen, Phtytophthora infestans, originated.
In a wide-ranging study of the genetic material found in P. infestans and other members of the Phytophthora species, the NC State researchers provide more evidence that P. infestans spread from South America to North America before wreaking havoc in Ireland in the 1840s. The pathogen still causes late-blight disease on potato and tomato plants around the world.

VR subway experiment highlights role of sound in disrupting balance for people with inner ear disorder
2025-01-24
The vestibular system is a network of organs in the inner ears that detects the motions and position of the head. The brain uses this information, along with inputs from the eyes and joints, to maintain the body’s balance.
Visual information has long been proven to affect balance—for example, strobe lights and swirling images can cause instability—but a new study published in PLOS ONE shows that sounds can also be a disruptive factor for those who have vestibular hypofunction, a vestibular system disorder resulting in impaired balance.
“People with vestibular hypofunction have ...
Evolution without sex: How mites have survived for millions of years
2025-01-24
In collaboration with colleagues from international partner institutions, researchers at the University of Cologne have investigated the asexual reproduction of oribatid mites using genome sequencing techniques. They show that the key to evolution without sex in oribatid mites may lie in the independent evolution of their two chromosome copies – a phenomenon known as the ‘Meselson effect’. The research team identified various mechanisms that may contribute to the genetic diversity of the chromosome ...

How human activity has shaped Brazil Nut forests’ past and future
2025-01-24
The significant decline in genetic diversity in the Amazon Basin, following historical events such as European colonisation, deforestation and the extinction of megafauna such as the sloth – the main seed dispersal agents, is of particular concern for the genetic health of Brazil Nut trees (Bertholletia excelsa). As one of the most impacted keystone species in rainforests, Brazil Nut trees are essential for biodiversity and a vital income source for local economies.
A crucial study led by researchers from the Max Planck Institute of Geoanthropology and the Max Planck Institute for Biology Tübingen ...
Doctors test a new way to help people quit fentanyl
2025-01-24
During the COVID-19 pandemic, when fentanyl overdoses surged, doctors were desperate to find ways of helping their patients.
They knew that buprenorphine could help people stop using opioids, but it was much harder to start the treatment for those who used fentanyl, which lasts longer in the body. Taking buprenorphine while fentanyl is still active can push someone abruptly into withdrawal.
So, they started giving patients small doses of the drug over a series of days to slowly build up the drug in their systems until their bodies could handle a higher dose of buprenorphine.
Now, ...
Long read sequencing reveals more genetic information while cutting time and cost of rare disease diagnoses
2025-01-24
One in every 10 people worldwide is impacted by a rare genetic disease but about 50% of them remain undiagnosed despite rapid increases in genetic technology and testing. Even when a person does have access to testing, the process of getting a diagnosis can take about five years or more, which is sometimes too late for patients, who are often children, to start the right treatment.
This is partly because current clinical testing uses a method called short-read sequencing, which cannot access information in certain regions of the genome and so may miss ...

Medicaid-insured heart transplant patients face higher risk of post-transplant complications
2025-01-24
A new study led by UCLA Health highlights the link between socioeconomic disadvantage, Medicaid insurance, and poorer survival rates after heart transplantation. Researchers found that Medicaid-insured heart transplant patients had a higher likelihood of developing cardiac allograft vasculopathy (CAV), a condition that affects transplanted hearts and can limit long-term survival. It has been reported that CAV contributes to more than 30% of all deaths in the first 5 to 10 years following heart transplantation.
The study, which included heart transplant recipients aged 18 and older, divided ...
Revolutionizing ammonia synthesis: New iron-based catalyst surpasses century-old benchmark
2025-01-24
NH3 is one of the most important chemicals in today’s world, as it is used in the production of fertilizers to boost agricultural yields and sustain the ever-growing global population. For over 100 years, NH3 production has relied on the Haber–Bosch (HB) process, which combines nitrogen (N2) and hydrogen in the presence of a catalyst. Interestingly, an iron-based catalyst developed a century ago (called ‘Promoted-Fe’) still remains at the forefront of mass NH3 production, despite countless efforts to find more energy-efficient alternatives. In the HB process, where NH3 is produced by a catalyst-filled reactor with a limited volume, ...

MIT method enables protein labeling of tens of millions of densely packed cells in organ-scale tissues
2025-01-24
A new technology developed at MIT enables scientists to label proteins across millions of individual cells in fully intact 3D tissues with unprecedented speed, uniformity, and versatility. Using the technology, the team was able to richly label whole rodent brains and other large tissue samples in a single day. In their new study in Nature Biotechnology, they also demonstrate that the ability to label proteins with antibodies at the single-cell level across whole brains can reveal insights left hidden by other widely used labeling methods.
Profiling the proteins that cells are making is a staple of studies in biology, neuroscience and related fields because the ...
Calculating error-free more easily with two codes
2025-01-24
Computers also make mistakes. These are usually suppressed by technical measures or detected and corrected during the calculation. In quantum computers, this involves some effort, as no copy can be made of an unknown quantum state. This means that the state cannot be saved multiple times during the calculation and an error cannot be detected by comparing these copies. Inspired by classical computer science, quantum physics has developed a different method in which the quantum information is distributed across several entangled quantum bits and stored redundantly in this ...
Dissolving clusters of cancer cells to prevent metastases
2025-01-24
Certain tumour types do not remain at their point of origin but spread throughout the body and form metastases. This is because the primary tumour continuously releases cancer cells into the blood. These circulating tumour cells (CTCs) can join together into small clusters of up to a dozen cells and settle in other organs. There, the clusters grow into larger tumours, known as metastases. Metastatic tumours are still a major medical problem: every year, around seven million people worldwide die from them.
One example of such a spreading tumour is breast cancer. As soon ...
