Immune response mechanism described for fate determination of T cells



Posted: 13 Sep 2018 12:00 PM PDT


Researchers have detailed a mechanism that sets the stage for the fate decision that gives rise to two major subsets of effector cells: T follicular helper cells and non-T follicular helper cells, known as Tfh and non-Tfh cells.


Cancer drug and antidepressants provide clues for treating brain-eating amoeba infections



Posted: 13 Sep 2018 11:33 AM PDT


Researchers have now identified three new molecular drug targets in Naegleria fowleri and a number of drugs that are able to inhibit the amoeba's growth in a laboratory dish. Several of these drugs are already approved by the US Food and Drug Administration for other uses, such as antifungal agents, the breast cancer drug tamoxifen and antidepressant Prozac.


A very special protein synthesis machinery



Posted: 13 Sep 2018 11:20 AM PDT


Sleeping sickness-causing parasites contain an unusual protein synthesis machinery. A team of researchers has resolved its very special structure for the first time.


High-resolution genomic map gives scientists unprecedented view of brain development



Posted: 13 Sep 2018 11:20 AM PDT


Researchers have created a massive database of the changes in gene activity of individual cells in the cerebellum during embryonic development and immediately after birth. The analysis of thousands of brain cells isolated from mice offers researchers a high-resolution map that enables scientists to view the detailed genomic changes cells undergo as the cerebellum wires its neural circuitry.


Malicious brain cell identified



Posted: 13 Sep 2018 11:20 AM PDT


Astrocytes' important role in brain function suggests they are also involved in disease. Now, scientists have identified an astrocyte subpopulation as the dominant cell type to spring into action in vivo in a neuroinflammatory disease setting.


Scientific institutions continue to lag behind the #TimesUp movement



Posted: 13 Sep 2018 11:20 AM PDT


Scientific and medical institutions must fundamentally reconsider how they address sexual harassment in the workplace, experts argue in a new article.


How a virus destabilizes the genome



Posted: 13 Sep 2018 11:19 AM PDT


New insights into how Kaposi's sarcoma-associated herpesvirus induces genome instability and promotes cell proliferation could lead to the development of novel antiviral therapies for KSHV-associated cancers.


How the immune system protects against Zika-induced neurological symptoms



Posted: 13 Sep 2018 11:19 AM PDT


A type of immune cell that produces a protein called CD4 plays an important role in protecting mice infected with the Zika virus against severe neurological disease, according to a new study.


Scientists use bear saliva to rapidly test for antibiotics



Posted: 13 Sep 2018 05:21 AM PDT


A team of scientists has discovered a technology that rapidly assesses potentially lifesaving antibiotics by using bacteria in saliva from an East Siberian brown bear.


Wearable ultrasound patch monitors blood pressure deep inside body



Posted: 12 Sep 2018 05:24 PM PDT


A new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin could help people detect cardiovascular problems earlier on and with greater precision. In tests, the patch performed as well as some clinical methods to measure blood pressure. Applications include real-time, continuous monitoring of blood pressure changes in patients with heart or lung disease, as well as patients who are critically ill or undergoing surgery.


Rare antibodies show scientists how to neutralize the many types of Ebola



Posted: 12 Sep 2018 05:24 PM PDT


Two new studies are bringing Ebola virus's weaknesses into the spotlight, showing for the first time exactly how human and mouse antibodies can bind to the virus and stop infection -- not only for Ebola virus, but for other closely related pathogens as well.


Requiring physical activity classes help sedentary college students be more active



Posted: 12 Sep 2018 05:24 PM PDT


Requiring physical activity classes in college encourages sedentary students to become more active, while elective classes tend to draw those who are already motivated, new research from Oregon State University has found.


Pilot study identifies strain of bacteria as chief risk factor for stomach cancer



Posted: 12 Sep 2018 11:44 AM PDT


Researchers have found a specific strain of Helicobacter pylori strongly correlated with stomach cancer.


Scientists map interactions between head and neck cancer and HPV virus



Posted: 12 Sep 2018 10:35 AM PDT


Scientists mapped the interactions between all HPV proteins and human proteins for the first time.


Thousands of breast cancer gene variants engineered and analyzed



Posted: 12 Sep 2018 10:34 AM PDT


A scientific analysis of nearly 4,000 mutations deliberately engineered into the BRCA1 gene will immediately benefit people undergoing genetic testing for breast or ovarian cancer risk. Many people obtaining genetic screenings previoulsy have learned that their BRCA1 gene contains a variant of uncertain significance. Data from this study now categorizes thousands of variants as behaving like disease mutations or not, providing new information important for medical care decisions.


Voting for the losing side can affect your performance at work



Posted: 12 Sep 2018 05:12 AM PDT


Companies should avoid scheduling important work tasks immediately following an election, according to a new study.


Critical differences in clots that cause a stroke



Posted: 12 Sep 2018 05:12 AM PDT


There are two main treatments for stroke caused by a clot in a blood vessel in the brain. Scientists have discovered that clots have different compositions and depending on where they are located in the brain, administering the clot-busting drug, Alteplase (also known as tPA), can be almost as effective as thrombectomy given sufficient time.
