Researchers shrink camera to the size of a salt grain
Micro-sized cameras have great potential to spot problems in the human body and enable sensing for super-small robots, but past approaches captured fuzzy, distorted images with limited fields of view. Now, researchers at Princeton University and the University of Washington have overcome these obstacles with an ultracompact camera the size of a coarse grain of […]
Persistence pays off in the human gut microbiome
The human gut microbiome is a complex community of trillions of microbes that are constantly interacting with each other and our bodies. It supports our wellbeing, immune system and mental health — but how is it sustained? Researchers in the UK and Germany, alongside other international collaborators, have investigated the evolution of bacteria in the […]
Amazon Rainforest birds’ bodies transform due to climate change
The most pristine parts of the Amazon rainforest devoid of direct human contact are being impacted by human-induced climate change, according to new research by LSU scientists. New analyses of data collected over the past four decades show that not only has the number of sensitive resident birds throughout the Amazon rainforest declined, but the […]
HPV Immunization Program Slashed New Cervical Cancer Cases
The introduction of a human papillomavirus (HPV) immunization program in England substantially reduced cases of cervical cancer and incidence of grade 3 cervical intraepithelial neoplasia (CIN3) in young women, particularly those who received the vaccine at the age of 12 or 13, researchers found. In their register-based population study, estimated relative reductions in cervical cancer […]
Linker histones tune the length and shape of chromosomes
Human life hinges on the ability of our cells to cram six feet of DNA into a 10-micron nucleus — equivalent to fitting a mile of string inside one green pea. But stuffing genes into cramped quarters is only half the battle. The DNA must also remain organized, carefully coiled into loops that ensure the […]
2 Win Nobel Prize In Medicine For Showing How We React To Heat, Touch
STOCKHOLM (AP) — Two scientists won the Nobel Prize in medicine on Monday for their discoveries into how the human body perceives temperature and touch, revelations that could lead to new ways of treating pain or even heart disease. Americans David Julius and Ardem Patapoutian identified receptors in the skin that respond to heat and […]
Power of stem cells harnessed to create cartilage tissue
Researchers at the University of Southampton have invented a new way to generate human cartilage tissue from stem cells. The technique could pave the way for the development of a much-needed new treatment for people with cartilage damage. Cartilage acts as a shock absorber in joints, but it is susceptible to damage through daily wear-and-tear, […]
MIND diet linked to better cognitive performance: Study finds diet may contribute to cognitive resilience in the elderly
Aging takes a toll on the body and on the mind. For example, the tissue of aging human brains sometimes develops abnormal clumps of proteins that are the hallmark of Alzheimer’s disease. How can you protect your brain from these effects? Researchers at Rush University Medical Center have found that older adults may benefit from […]

A new way to solve the ‘hardest of the hard’ computer problems: Scientists develop the next generation of reservoir computing
A relatively new type of computing that mimics the way the human brain works was already transforming how scientists could tackle some of the most difficult information processing problems. Now, researchers have found a way to make what is called reservoir computing work between 33 and a million times faster, with significantly fewer computing resources […]
