Young adults who used marijuana only recreationally showed significant abnormalities in two brain regions that are important in emotion and motivation. This is the first study to show casual use of marijuana is related to major brain changes.
Using just a single drop of blood, a team of UW-Madison researchers has developed a faster,...
Delivering chemotherapy drugs in nanoparticle form could help reduce side effects by targeting...
Psychologists have presented the first study to reveal that our brains rely on an active suppression mechanism to avoid being distracted by salient irrelevant information when we want to focus on a particular item or task.
It’s long been known that certain strains of human papillomavirus (HPV) cause cancer. Now, researchers have determined a new way that HPV might spark cancer development– by disrupting the human DNA sequence with repeating loops when the virus is inserted into host-cell DNA as it replicates.
Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.
The editors of R&D Magazine have announced that there is still plenty time to prepare your Entry Form for the 2014 R&D 100 Awards: Friday, May 2 is the new deadline.
Pall introduced a 13 mm Acrodisc MS syringe filter certified for low extractables in high performance liquid chromatography/mass spectrometry (LCMS) applications. The new 13 mm size, which is designed specifically for small sample analysis using LCMS, complements Pall’s current Acrodisc MS syringe filter offering of a 25 mm filter.
The Axio Scan.Z1, an automated microscope from Carl Zeiss Microscopy, allows researchers to digitalize fixed tissue sections and cytologic specimens in bright-field and fluorescence. As many as 100 microscope slides can be digitized at one time. The Axio Scan.Z1 captures the entire specimen area of the microscope slide, including the edge.
A high-tech screening tool for cervical cancer is facing pushback from more than a dozen patient groups, who warn that the genetic test could displace a simpler, cheaper and more established mainstay of women's health: the Pap smear. The new test comes from Roche and uses DNA to detect the human...
Limiting a certain protein in the brain reverses Alzheimer’s symptoms in mice, report neuroscientists at MIT’s Picower Institute for Learning and Memory. Researchers found that the overproduction of the protein known as p25 may be the culprit behind the sticky protein-fragment clusters that build up in the brains of Alzheimer's patients.
Depression can hit young fathers hard- with symptoms increasing dramatically during some of the most important years of their children’s lives, a new study has found.
The first human volunteer will receive red blood cells cultured in the laboratory within the next three years, as part of a long-term research program funded by the Wellcome Trust.
As many as 10 percent of women with a personal or family history of breast or ovarian cancer have at least one genetic mutation that, if known, would prompt their doctors to recommend changes in their care, according to a new study by researchers at the Stanford University School of Medicine.
If you follow cancer biology, then you’ve probably heard of ubiquitin before. In a recent paper researchers provided a structural rationale for how ubiquitin helps RIG-I do its job— and how that might help keep the immune system from getting out of hand.
A mumps outbreak in central Ohio has grown to more than 200 confirmed cases, public health officials said. A total of 212 cases of the contagious viral illness, with 132 of those linked to Ohio State University, have been reported.
A tiny genetic molecule known as a microRNA plays a central role in bowel cancer and could be key to developing new treatments for the disease, a new study concludes. Scientists found that the molecule, called microRNA 135b, is a vital ‘worker’ employed by several important cancer genes to drive the growth of bowel cancers.
