Taking a cue from biological cells, researchers from MIT, Columbia University, and elsewhere have developed computationally simple robots that connect in large groups to move around, transport objects, and complete other tasks.
A world free of tuberculosis (TB) is possible by 2045 if increased political will and financial resources are directed towards priority areas including providing evidence-based interventions to everyone, especially to high risk groups, and increasing research to develop new ways to diagnose, treat, and prevent TB. Funding this response will require substantial investments, and accountability mechanisms will be necessary to ensure that promises are kept and targets are reached.
Scientists at Queen Mary University of London have discovered a never before reported behaviour of queen bumblebees.
A simple new technique developed by engineers from the University of California, Riverside that can detect fake drugs from a video taken as the sample undergoes a disturbance. Called 'chronoprinting,' the technology requires only a few relatively inexpensive pieces of equipment and free software to accurately distinguish pure from inferior food and medicines.
When rectal cancer infiltrates lymph nodes, patients may have better clinical outcome if chemo/radiotherapy are administered before surgery. However, the lymph nodes' status can only be precisely assessed upon removal during this same surgery. To find a way out of this 'Catch,' a multidisciplinary team, developed an MRI methodology, called SPI, that identifies infiltrated lymph nodes. SPI can help define treatment strategy for rectal cancer patients and may have future implications for other malignancies.
Researchers at Columbia Engineering and MIT Computer Science & Artificial Intelligence Lab (CSAIL), demonstrate for the first time a way to make a robot composed of many loosely coupled components, or 'particles.' Unlike swarm or modular robots, each component is simple, and has no individual address or identity. In their system, which the researchers call a 'particle robot,' each particle can perform only uniform volumetric oscillations (slightly expanding and contracting), but cannot move independently.
As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations? Researchers at UC Santa Cruz have now demonstrated that epigenetic information carried by parental sperm chromosomes can cause changes in gene expression and development in the offspring.
UC San Diego School of Medicine research sets the stage for clinicians to potentially one day use levels of a pancreatic cancer patient's PHLPP1 and PKC enzymes as a prognostic, and for researchers to develop new therapeutic drugs that inhibit PHLPP1 and boost PKC as a means to treat the disease.
Researchers have identified a single genetic alteration in a malaria-transmitting mosquito species that confers resistance to a widely used insecticide, according to a new study.
Using data from computed tomography (CT) images, researchers may be able to predict which lung cancer patients will respond to chemotherapy, according to a new study.
