Penn researchers develop new mathematical model to estimate mutation rates in the human genome

It turns out that the type, how frequent, and where new mutations occur in the human genome depends on which DNA building blocks are nearby, found researchers from the Perelman School of Medicine at the University of Pennsylvania in an advanced online study published this week in Nature Genetics.

Scientists find that lifespan of supportive cells in tumor may control cancer metastasis

Researchers have discovered that eliminating cells thought to aid tumor growth did not slow or halt the growth of cancer tumors. In fact, when the cancer-associated fibroblasts (CAFs), were eliminated after 10 days, the risk of metastasis of the primary tumor to the lungs and bones of mice increased dramatically.

New article describes recent efforts made by researchers to classify bladder cancers

The ability to map the human genome has transformed how scientists and researchers classify various cancers. In the past, cancer cells were examined through a microscope and their appearance, often enhanced with dyes or other agents, was used to categorize the type of cancer.

New study focuses on safety of using induced pluripotent stem cells in patients

A new study led by scientists at The Scripps Research Institute and the J. Craig Venter Institute shows that the act of creating pluripotent stem cells for clinical use is unlikely to pass on cancer-causing mutations to patients.

UGA scientists discover link between genetics and aging process

Scientists at the University of Georgia have shown that a hormone instrumental in the aging process is under genetic control, introducing a new pathway by which genetics regulates aging and disease.

New discoveries provide further evidence for benefits of a good night's sleep

Why does sleeping on it help? This is the question tackled by new research at the University of Bristol, which reveals how brain activity during sleep sorts through the huge number of experiences we encounter every day, filing only the important information in memory.

Researchers identify common molecular alteration in glioblastoma

Glioblastoma is the most aggressive manifestation of brain tumours. Due to its high invasive capacity and uncontrolled, infiltrating growth, it is particularly difficult to manage. Currently, the treatment for this disease consists of a combination of surgery (when possible), radiation and chemotherapy.

Air pollution exposure increases obesity risk

Laboratory rats who breathed Beijing's highly polluted air gained weight and experienced cardio-respiratory and metabolic dysfunctions after three to eight weeks of exposure.

OmniVision and FISBA announce microcamera solution for life science applications

OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, and FISBA AG, a world leader in customized optical components, systems and microsystems, today announced a new microcamera solution for life science applications. FISBA’s FISCam™ is a customizable microcamera with integrated illumination that comes in a compact package measuring less than 2 mm in diameter. This new microcamera uses OmniVision’s high-performance OV6946 CameraChip™ sensor to deliver striking images and video in 400 x 400 resolution even with the extremely small module size.

Kellogg investigators develop new nanotechnology that has potential to kill tumor cells in the eye

Researchers at the University of Michigan Kellogg Eye Center have developed a new nanoparticle that uses a tumor cell's protective mechanism against itself -- short-circuiting tumor cell metabolism and killing tumor cells.

KU Leuven scientists improve survival of implanted bone cells

To treat a complicated, non-healing bone defect, surgeons often use an implant with living cells to promote bone repair, but the implanted cells have a small chance of surviving because they are not prepared for a lack of oxygen and nutrients at the fracture site.

Acute heart failure patients often have high levels of red meat metabolite

Patients with acute heart failure often have high levels of the metabolite trimethylamine N-oxide (TMAO) - of which red meat is a major dietary source - according to researchers from the University of Leicester.

Researchers examine molecular profile of HPV-positive oropharyngeal squamous cell carcinoma

Throat cancer patients exposed to both human papillomavirus (HPV) and tobacco smoke demonstrate a pattern of mutations along several key cancer genes, according to research presented today at the 2016 Multidisciplinary Head and Neck Cancer Symposium.

FDA-approved Alzheimer's medications may help people quit smoking

Despite several safe drug therapies available to help smokers quit, three-quarters report relapsing within six months of a quit attempt. University of Pennsylvania researchers Rebecca Ashare and Heath Schmidt saw potential for a permanent cessation solution in a class of FDA-approved medications used to improve cognitive impairments from Alzheimer's disease.

Virginia Tech scientist finds way to potentially track and stop viruses

Viruses are molecular thieves that take from their hosts under the cloak of darkness. But now a Virginia Tech scientist has found a way to not only track viral hijackers, but also potentially stop them from replicating.

NK cells produce VEGF-A that promotes tumor growth

The immune system protects the body against cancer cells. The Elimination of cancer cells is an important task of NK cells. For NK cells to function properly, they require the activator STAT5.

SBP study opens door for new approaches to treat muscle diseases

Scientists at Sanford Burnham Prebys Medical Discovery Institute have found a key to enhancing repair of damaged muscle. In work published today in Cell Reports, scientists describe why fetal muscle stem cells (MuSCs) are better at regenerating muscle compared to adult MuSCs.
