Researchers discovered an entirely new human blood type after solving a 50-year mystery.
Back in 1972, doctors were stumped when a pregnant woman’s blood sample was missing a surface molecule that was present on everyone else’s red blood cells at the time. No one could explain it.
Fast forward fifty years, and scientists believe to have sussed it. The discovery led researchers from the UK and Israel to describe a new blood group system in humans, publishing their findings in 2024.
A team of engineers at Georgia Institute of Technology’s Wearable Intelligent Systems and Healthcare Center, working with colleagues affiliated with several institutions in South Korea, has developed a microscale brain–computer interface that is small enough to be placed between hair follicles on a user’s head.
In their paper published in the Proceedings of the National Academy of Sciences, the group describes how they made their interface, how it attaches to other hardware to allow readings to be captured and how well it worked during testing.
Over the past several decades, brain–computer interfaces have been developed that are capable of reading brain waves and responding to them in useful ways. These devices can be used to control a cursor on a computer screen, for example, or to choose buttons to press. Such devices are still in limited use, however, mainly due to their bulky nature. In this new effort, the researchers have developed a sensor so small it can be placed on the scalp between hair follicles.
Australia has a maths problem. A new Grattan report shows that one in three Australian school students fail to achieve proficiency in maths.
The report, The Maths Guarantee: How to boost students’ learning in primary schools, shows that students from disadvantaged backgrounds struggle the most with maths. But one in five students from well-off families struggle too.
In a 2023 international maths test, only 13 per cent of our Year 4 students excelled, compared to 22 per cent in England and 49 per cent in Singapore.
More Americans are receiving computed tomography (CT) scans than ever before, and while this technology can save lives, some scientists are concerned about the potential for low doses of ionizing radiation to increase cancer risks.
(Spanish: [sanˈtjaɣo raˈmon i kaˈxal] ; 1 May 1852 – 17 October 1934) [ 1 ] [ 2 ] was a Spanish neuroscientist, pathologist, and histologist specializing in neuroanatomy and the central nervous system. He and Camillo Golgi received the Nobel Prize in Physiology or Medicine in 1906. [ 3 ] Ramón y Cajal was the first Spaniard to win a scientific Nobel Prize. His original investigations of the microscopic structure of the brain made him a pioneer of modern neuroscience.
The Utah State Board of Education is looking at how artificial intelligence can be utilized and restricted in classrooms. Parents said they see how AI is affecti
ADHD is apparently an unclassifiable, unmeasurable disorder that requires costly amphetamines to remedy.
Researchers at Children’s Hospital of Philadelphia (CHOP) developed a longitudinal atlas of neuroblastoma, a common and potentially deadly childhood cancer, to gain a deeper understanding into precise molecular mechanisms underlying why and how certain treatments eventually become ineffective.
The findings, which offer insights that could potentially lead to new personalized medicine approaches in neuroblastoma treatment, were published today in the journal Nature Genetics.
Despite significant advances in the standard of care, the 5-year survival rate of high-risk neuroblastoma after diagnosis remains less than 50%. Neuroblastoma cells within the same tumor can vary greatly, which creates challenges in treatment efficacy. Until now, the scientific community lacked understanding of how the tumor microenvironment changes during treatment.
For the first time, scientists have generated a functional neural pathway for sensing pain in a dish. This could help unravel mechanisms of pain disorders.
