Rutgers researchers have created a device that can determine whether targeted chemotherapy drugs are working on individual cancer patients.
The portable device, which uses artificial intelligence and biosensors, is up to 95.9 percent accurate in counting live cancer cells when they pass through electrodes, according to a study in the journal Microsystems & Nanoengineering.
Initiating stroke treatment just 15 minutes faster can save lives and prevent disability, according to a new UCLA-led study, published today in JAMA.
The abnormal accumulation of proteins in the brain is a biological marker for Alzheimer's disease, but the ways in which these proteins spread may help explain why the prevalence of Alzheimer's is higher in women than in men.
A recent study by researchers from the Center for Cognitive Medicine (CCI) at Vanderbilt University Medical Center identified differences in the spread of a protein called tau -- which is linked to cognitive impairment -- between men and women, with women showing a larger brain-wide accumulation of tau than men due to an accelerated brain-wide spread.
Carbofuran is a plant protection product which can be used against certain insects, mites, ticks and nematodes. On the basis of the amount of the carbofuran residues and estimated dietary intake of red chilies, an exceedance of the acute reference dose (ARfD) is not to be expected for children or adults. The ARfD describes the quantity of a substance per kilogram of body weight that consumers can ingest with their food in one meal or in several meals spread over one day without any recognisable effect on health.
BUFFALO, N.Y. -- It seems like everything is going wireless these days. That now includes efforts to reprogram the human genome.
A new University at Buffalo-led study describes how researchers wirelessly controlled FGFR1 -- a gene that plays a key role in how humans grow from embryos to adults -- in lab-grown brain tissue.
The ability to manipulate the gene, the study's authors say, could lead to new cancer treatments, and ways to prevent and treat mental disorders such as schizophrenia.
One type is micro-RNA (miRNA), and its job is to regulate numerous processes in a cell. It has been suggested, however, that some of these miRNAs are involved in the emergence of tumours and other health problems.
The second release of data from Gaia star-mapping satellite, published in 2018, has been revolutionising many fields of astronomy. The unprecedented catalogue contains the brightness, positions, distance indicators and motions across the sky for more than one billion stars in our Milky Way galaxy, along with information about other celestial bodies.
PITTSBURGH, July 16, 2019 - Death rates from sepsis fell faster in New York than expected--and faster than in peer states--following the introduction of the nation's first state-mandated sepsis regulation, according to an analysis led by University of Pittsburgh researchers and published today in JAMA.
What The Study Did: Hospital discharge data was used to examine the association between New York state sepsis regulations and the outcomes of patients hospitalized with sepsis.
Authors: Jeremy M. Kahn, M.D., M.S., of the University of Pittsburgh, is the corresponding author.

Lung cancer patients who had a hurricane disaster declared during radiotherapy had worse overall survival than those who completed treatment in normal circumstances, with longer disaster declarations associated with increasingly worse survival. The finding comes from a report by American Cancer Society investigators published in JAMA, which suggests several mitigation strategies, including arranging for transferring treatment and eliminating patient out-of-network insurance charges during disasters.
Modeling the shape and movement of near-Earth asteroids is now up to 25 times faster thanks to new Washington State University research.
The WSU scientists improved the software used to track thousands of near-Earth asteroids and comets, which are defined as being within 121 million miles or about 1.3 times the distance to the sun.
Their work provides a valuable new tool for studying asteroids and determining which of them might be on a collision course with Earth.
Researchers have discovered a new species of tree in the Usambara Mountains in Tanzania, part of the Eastern Arc Mountains, and a globally important region for species in need of conservation.
The tree, which grows up to 20m tall and has white flowers, has been categorised as endangered due to its restricted population range at only 8km-sq. It is as yet unknown what kind of wildlife might rely on the tree, but it is most likely pollinated by a species of beetle.
UNIVERSITY PARK, Pa.--Liberal-leaning companies are more likely to work in concert with the demands of activists of all kinds than conservative-leaning companies, according to researchers at Penn State and the University of Washington. The findings suggest that not all companies make concessions to activists as a result of threats but may instead have a workforce that is more amenable to activists' requests.
Removing the barriers of access to technology does not close the digital divide for African American and older patients, according to new research from The Ohio State University College of Medicine.
Recording the movements of people and animals (including birds and insects) has become very easy because of the development of small and inexpensive GPS devices and video cameras. However, it is still difficult to infer what triggers such movements (for example, external stimuli and/or their mental processes) from the behavioral records.
