Immune system-in-a-dish offers hope for 'bubble boy' disease

Researchers at Salk Institute have developed a new method to convert cells from x-linked SCID patients into stem cell-like state, fix the genetic mutation and prompt corrected cells to successfully generate NK cells in the laboratory. This technique could lead to a more effective and less invasive treatment for this devastating disease.

New work schedule could cure your 'social jetlag'

Researchers report that aligning work schedules with employees' biological clocks can improve sleep duration and quality, as well as social jetlag and general wellbeing. The study found that flexible work schedules reduced stress and improved satisfaction with leisure time.

You are when you eat

A new study by researchers at San Diego State University found that limiting fruit flies' eating hours can prevent aging- and diet-related heart problems. Flies on a time-restricted feeding schedule slept better, didn't gain as much weight and had healthier hearts than those that ate anytime.

Gene leads to malformation of the urinary tract

A study published in PLOS Genetics has identified a gene, ISL1, associated with classic bladder exstrophy, a rare congenital anomaly of the urinary tract. The discovery is significant for understanding the disease's development and may lead to preventive measures during pregnancy.

Magnetic brain stimulation

Researchers at MIT have developed a method to stimulate brain tissue using external magnetic fields and injected magnetic nanoparticles. The approach can provide an implant-free means of providing brain stimulation and mapping, potentially treating neurological diseases such as Parkinson's disease.

Geography matters: Imaging overuse seen in certain US regions

A new study from NYU Langone Medical Center found that over 40% of low-risk prostate and breast cancer patients in certain US regions received inappropriate tests. The research suggests that regional culture and infrastructure play a significant role in the use of imaging tests, with some areas exhibiting more appropriate use than others.

Prescription for living longer: Spend less time alone

A new study from Brigham Young University finds that loneliness and social isolation are major risk factors for mortality across all ages and income levels. The research analyzed data from over 3 million participants and found that the lack of social connections presents an added risk, while the existence of relationships provides a po...

Study shows even injured kidneys can be used for transplants

A Yale-led study found that donated kidneys with acute injury are associated with delayed graft function but not poor long-term transplant outcomes. The research suggests that injured kidneys could be used for transplants, potentially increasing the number of available organs and improving survival rates for patients on dialysis.

Researchers develop 'visual Turing test'

A new system designed by researchers from Brown and Johns Hopkins universities aims to assess computer vision systems' ability to understand the context of an image. The 'visual Turing test' evaluates how well computers can recognize subtle details, such as people walking together and having a conversation.

The physics of clouds

Researchers use a cylindrical rotating system to study turbulent convection, disproving the idea that transitions from one state of turbulence to another are smooth. Their findings suggest that symmetry changes must be sharp, contradicting Lev Landau's theory.

Study reveals sexual appeal of war heroes

A study published in Evolution and Human Behaviour found that women are more attracted to war heroes than regular soldiers or men who display heroic traits in other fields. The researchers also discovered that heroism in combat increases women's levels of sexual attraction towards male soldiers, but not in disaster zones.
