Electrical and computer engineering professor Barry Van Veen wears an electrode net used to monitor brain activity via EEG signals.
As real as that daydream may seem, its path through your brain runs opposite reality.

Hox genes are master body-building genes that specify where an animal's head, tail and everything in between should go. There's even a special Hox gene program that directs the development of limbs and fins, including specific modifications such as the thumb in mice and humans. Now, San Francisco State University researchers show that this fin- and limb-building genetic program is also utilized during the development of other vertebrate features.

Microbiologists at NYU Langone Medical Center say they have what may be the first strong evidence that the natural presence of viruses in the gut -- or what they call the 'virome' -- plays a health-maintenance and infection-fighting role similar to that of the intestinal bacteria that dwell there and make up the "microbiome."

Looking across evolutionary time and the genomic landscapes of humans and mice, an international group of researchers has found powerful clues to why certain processes and systems in the mouse - such as the immune system, metabolism and stress response - are so different from those in people. Building on years of mouse and gene regulation studies, they have developed a resource that can help scientists better understand how similarities and differences between mice and humans are written in their genomes.

Organs can become significantly damaged during transplantation, but a new article published in the BJS (British Journal of Surgery) offers a protective strategy that could keep them safe and allow them to function optimally after the procedure.

Chronic myeloid leukemia develops when a gene mutates and causes an enzyme to become hyperactive, causing blood-forming stem cells in the bone marrow to grow rapidly into abnormal cells. The enzyme, Abl-kinase, is a member of the "kinase" family of enzymes, which serve as an "on" or "off" switch for many functions in our cells. In chronic myeloid leukemia, the hyperactive Abl-kinase is targeted with drugs that bind to a specific part of the enzyme and block it, aiming to ultimately kill the fast-growing cancer cell. However, treatments are often limited by the fact that the cancer cells can adapt to resist drugs. EPFL scientists have identified an alternative part of Abl-kinase on which drugs can bind and act with a reduced risk of drug resistance. Their work is published in Nature Communications.

Scientists have demonstrated for the first time that a single-dose, needleless Ebola vaccine given to primates through their noses and lungs protected them against infection for at least 21 weeks. A vaccine that doesn't require an injection could help prevent passing along infections through unintentional pricks. They report the results of their study on macaques in the ACS journal Molecular Pharmaceutics.

WCS scientists in the Democratic Republic of Congo (DRC) have discovered a new species of plant living in a remote rift valley escarpment that's supposed to be inside of a protected area. But an administrative mapping error puts the reserve's borders some 50 kilometers west of the actual location. Now the new species, along with 900 other plant varieties and 1,400 chimpanzees, are in limbo with no protection and threatened by cattle ranches and forest destruction.

Researchers at Washington University School of Medicine in St. Louis led an international team that sequenced and analyzed the cat genome to better understand the animal's domestication.
Cats and humans have shared the same households for at least 9,000 years, but we still know very little about how our feline friends became domesticated. An analysis of the cat genome by researchers at Washington University School of Medicine in St. Louis reveals some surprising clues.

Although gluten-free foods are trendy among the health-conscious, they are necessary for those with celiac disease. But gluten, the primary trigger for health problems in these patients, may not be the only culprit. Scientists are reporting in ACS' Journal of Proteome Research that people with the disease also have reactions to non-gluten wheat proteins. The results could help scientists better understand how the disease works and could have implications for how to treat it.
