Breakthrough: Scientists create powerful cancer-fighting T cells directly inside the body.

This study developed a way to precisely engineer a patient's own immune cells *in vivo*, giving them new genetic instructions to fight diseases like cancer. This could make life-saving cell therapies much cheaper and more accessible than current lab-intensive methods. - Read more: https://t.co/elQlCizTsG

1 in 4 papers still have at least 1 partially or fully hallucinated reference.

[Reviewer3 @reviewer3com]

Last month, arXiv announced a one year ban for authors who submit papers with unchecked AI use, including hallucinated references.

We decided to test how this new policy was working. Using Reviewer3’s reference checker followed by manual verification, we sampled 200 papers submitted to arXiv on June 10th, well after the ban announcement, and found some concerning results:

1 in 4 arXiv papers still contain at least one partially or fully hallucinated reference.

Results:
- 55/200 (27% of papers) still contained at least one partially or fully hallucinated reference.
-29/200 (14%) had more than one.
-117 total invalid references were identified.
-The most common hallucination was an author mismatch. 25/117 fabricated references contained titles of real manuscripts but fumbled the listed authors.

One month after the arXiv ban and there are still plenty of hallucinated references.

[Reviewer3 @reviewer3com]

Last month, arXiv announced they will begin banning authors for one year if they submit manuscripts with unchecked AI generation, particularly hallucinated references.

Unmasking the duo that supercharges the most common thyroid cancer.

Scientists discovered how a key cancer-promoting protein, FGFR1, becomes overactive in the most common thyroid cancer. They found two specific proteins, USP7 and YY1, act as "on" switches, stabilizing FGFR1 and boosting its production, which reveals promising new targets for treatment. - Read more: https://t.co/sePj7350qS

New Drug Doubles Survival for Advanced Pancreatic Cancer Patients
Researchers found that a new targeted drug, daraxonrasib, significantly extended the lives of patients with previously treated advanced pancreatic cancer, nearly doubling their overall survival compared to standard chemotherapy. This represents a major advance for a cancer with very limited treatment options, offering a promising new way to fight the disease. - Read more: https://t.co/nKXpbz1Aoq

Your body's own molecule could be a secret weapon against cancer.

Researchers discovered that spermine, a natural compound, acts as an iron shield to prevent a specific type of cell death, ferroptosis, which is important in liver cancer. This finding suggests new ways to fight tumors by blocking spermine production or protect healthy tissues from damage by supplementing it. - Read more: https://t.co/7Ba0BviFcF

Global deaths from stomach and gut infections plummeted by two-thirds since 1990, but still claim over a million lives annually.

This major study tracked deaths and illness from gut infections like diarrhea and typhoid globally from 1990 to 2023, revealing a two-thirds drop in annual deaths, from nearly 3.7 million to 1.27 million. Despite this progress, these diseases remain a top killer of young children, particularly in South Asia and sub-Saharan Africa, highlighting the urgent need for continued prevention efforts. - Read more: https://t.co/sHdBs9A9rT

Your thyroid care during pregnancy just got a major upgrade.
An international panel of experts released comprehensive, updated guidelines for diagnosing and managing thyroid conditions in women planning pregnancy, pregnant, or postpartum. This ensures women receive the best available care, improving health for both mothers and their babies. - Read more: https://t.co/XYbuZwWr0d

Removing tonsils and adenoids linked to HIGHER risk of pediatric MS.

A new study investigated children with and without pediatric multiple sclerosis, finding that those who had their tonsils and adenoids removed had a 63% increased chance of developing MS. For children already diagnosed, this surgery also doubled their rate of relapses, suggesting these immune tissues play a crucial, unexpected role in MS development and progression. - Read more: https://t.co/YzQ3WGWcjV

New drug doubles survival for patients with advanced pancreatic cancer.

A new study tested an oral drug, daraxonrasib, against standard chemotherapy for previously treated advanced pancreatic cancer, finding it doubled median overall survival from 6.6 months to 13.2 months and caused fewer severe side effects. This offers a major new treatment option for a very aggressive cancer, especially for patients with common RAS gene mutations, where current therapies are limited. - Read more: https://t.co/nKXpbz1Aoq

New Drug Offers Functional Cure for Nearly 1 in 5 Hepatitis B Patients

In two large studies, a drug called bepirovirsen helped about 20% of chronic Hepatitis B patients achieve a "functional cure," meaning the virus was controlled and a key marker disappeared long-term. This marks a significant step forward in treating a condition that previously had limited options for lasting suppression. - Read more: https://t.co/PmApNh18Pb

Nearly half of cancer patients reported tumor regression or no disease after taking two common repurposed drugs.

A new observational study tracked 122 cancer patients who took ivermectin and mebendazole, drugs typically used for parasites, off-label. Researchers found that 84.4% of participants reported a clinical benefit, with 48.4% experiencing tumor shrinkage or no evidence of disease, and the drugs were well-tolerated. This real-world data suggests these accessible medications could be a promising area for further cancer research in rigorous clinical trials. - Read more: https://t.co/fyb7MQfixZ

New Drug Combination Significantly Extends Survival for Advanced Stomach and Esophageal Cancer.
Scientists compared a new dual-targeted drug called zanidatamab, with chemotherapy (and sometimes an immunotherapy), against standard treatment for advanced stomach and esophageal cancers. They found that these new combinations significantly delayed cancer progression, and the triple therapy also helped patients live longer overall, offering a vital new option for this aggressive disease. - Read more: https://t.co/X2scYfkDAz

Brain cells 'donate' healthy mitochondria to fight Alzheimer's.

This study found that microglia, the brain's immune cells, can transfer functional mitochondria—the "powerhouses" of cells—to astrocytes, which are crucial support cells. This transfer, mediated by a protein called GPNMB, significantly improved astrocyte function and reduced cognitive decline in mice with Alzheimer's-like pathology. This discovery reveals a surprising natural defense mechanism and offers a promising new direction for developing treatments for Alzheimer's disease. - Read more: https://t.co/jFwaXVhUuN

Mental disorders are now the world's leading cause of disability.

A major global study tracking health trends since 1990 found over a billion people worldwide experienced a mental disorder in 2023, nearly doubling the number of cases. This makes mental disorders the fifth leading cause of overall health burden globally, highlighting an urgent need for better prevention and treatment strategies across all countries. - Read more: https://t.co/aG05XDeHeC

Sperm can generate and transmit novel traits in a way that rewrites the rules of inheritance.

This study reveals how sperm can take up foreign genetic material and, using a special enzyme, convert it into new genetic instructions called 'retro-genes.' These retro-genes are passed to offspring, introducing new characteristics that don't follow traditional inheritance patterns, offering a surprising new pathway for genetic change. - Read more: https://t.co/XbCTUcPE2G

For the first time, researchers observe matter that is both solid and superfluid.

Researchers studied a special quantum fluid and watched it transform into an insulating solid. This newly observed solid is a "supersolid," a theorized state that is both rigid like a crystal and flows without friction, created purely by the particles' own interactions. This discovery opens new avenues for understanding and engineering quantum materials. - Read more: https://t.co/X8sGp8rcvf
