Three ways Facebook could reduce fake news without resorting to censorship

The public gets a lot of its news and information from Facebook. Some of it is fake. That presents a problem for the site's users, and for the company itself.

The filter bubble isn't just Facebook's fault—it's yours

Following the shock results of Brexit and the Trump victory, a lot of attention has focused on the role that Facebook might have played in creating online political ghettos in which false news can easily spread. Facebook now has serious political influence thanks to its development from a social networking tool into a primary source of news and opinions. And for many, the way it manages this influence is in need of greater scrutiny. But to put the blame solely on the company is to overlook how people use the site, and how they themselves create a filter bubble effect through their actions.

In-memory de-duplication technology to accelerate response for large-scale storage

Fujitsu Laboratories today announced the development of a high-speed in-memory data deduplication technology for all-flash arrays, which are large-scale, high-speed storage systems and use multiple flash devices such as solid-state drives. This technology enables the production of storage systems with up to twice the response speed when writing data, compared to previous methods. In recent years, all-flash arrays have incorporated deduplication technology that consolidates duplicate data into one to write to a flash device, in order to utilize the limited capacity of flash devices. However, as the system connects to multiple flash devices through a network in order to search for duplicate data each time it writes data, and storage devices grow in capacity and increase in speed, a problem of lowered response speed during write operations arises.

For the first time, researchers reveal a causal link between RNA splicing and aging

Aging is a key risk factor for a variety of devastating, chronic diseases, yet the biological factors that influence when and how rapidly cells deteriorate over time remain largely unknown. Now, for the first time, a research team led by Harvard T.H. Chan School of Public Health has linked the function of a core component of cells' machinery—which cuts and rejoins RNA molecules in a process known as "RNA splicing"—with longevity in the roundworm. The finding sheds light on the biological role of splicing in lifespan and suggests that manipulating specific splicing factors in humans might help promote healthy aging.

'Shock and kill' strategy for curing HIV may endanger patients' brains

Combination drug treatments have become successful at long-term control of HIV infection, but the goal of totally wiping out the virus and curing patients has so far been stymied by HIV's ability to hide out in cells and become dormant for long periods of time. Now a new study on HIV's close cousin, simian immunodeficiency virus (SIV), in macaques finds that a proposed curative strategy could backfire and make things worse if the virus is in fact lurking in the brain.

New compound targets TB bacterium's defense against the immune system

Part of the reason tuberculosis-causing bacteria are so good at colonizing the human body is that they have defenses against the body's immune system. A research team led by a Brown University chemist has developed a new compound that can take down one of those defenses in Mycobacterium tuberculosis. The researchers are hopeful that the compound could be part of a new drug strategy for treating tuberculosis.

Scientists find that for stem cells to be healthy, telomere length has to be just right

Ever since researchers connected the shortening of telomeres—the protective structures on the ends of chromosomes—to aging and disease, the race has been on to understand the factors that govern telomere length. Now, scientists at the Salk Institute have found that a balance of elongation and trimming in stem cells results in telomeres that are, as Goldilocks would say, not too short and not too long, but just right.

Geophagy—"soil-eating" as an addictive behaviour

Between 30 and 80 percent of people in Africa, especially women, regularly eat clayey soil – this habit is known as geophagy. They often consume between 100 and 400 g per day. "Pregnant and breast-feeding women, in particular, nearly always have some soil to eat. This is cheap to buy in the marketplace," explains Ruth Kutalek of MedUni Vienna's Center for Public Health (Institute of Social Medicine). The reason behind this habit, which was previously also widespread in Europe and Asia, is still unclear and is largely unresearched. A study conducted at MedUni Vienna has now been able to show that it is a craving.

No safe level of smoking: Even low-intensity smokers are at increased risk of earlier death

People who consistently smoked an average of less than one cigarette per day over their lifetime had a 64 percent higher risk of earlier death than never smokers, and those who smoked between one and 10 cigarettes a day had an 87 percent higher risk of earlier death than never smokers, according to a new study from researchers at the National Cancer Institute (NCI). Risks were lower among former low-intensity smokers compared to those who were still smokers, and risk fell with earlier age at quitting. The results of the study were reported December 5, 2016, in JAMA Internal Medicine.

How human NK cells destroy diseased cells and minimize damage to bystanders

When NK cells encounter cancer or virally infected cells, they adhere to them and quickly congregate their destructive granules on the area of contact with the diseased cell. The granules, which contain molecules that can destroy a cell, are then released onto the target cell to kill it. Scientists at Baylor College of Medicine, Texas Children's Hospital, Rice University, the KTH Royal Institute of Technology and the Karolinska Institute have discovered that congregating the granules before releasing them onto the target cell improves the efficiency of the NK cell attack on diseased cells and minimizes the killing of healthy bystander cells. The results appear in the Journal of Cell Biology.

Advanced imaging of intact brains during ischemic stroke reveals a new role for pericytes

Pericytes are the primary locus of matrix-mellaproteinase-9-dependent (MMP-9) capillary damage and blood leakage during ischemia, according to preclinical findings reported by Medical University of South Carolina (MUSC) investigators in an article published online on November 14, 2016 by The Journal of Neuroscience. In vivo two-photon microscopy revealed MMP-9 activity and plasma leakage disproportionately occurred at locations where pericyte somata were attached to the endothelium. These results suggest that pericytes, normally essential for blood-brain barrier (BBB) function, contribute to capillary damage during stroke.

CAR T cell immunotherapy continues to yield complete responses in leukemia

Poor anti-VEGF responses linked to genetic variation in immune regulation

Anti-VEGF therapies are commonly used to stabilize deteriorating vision in patients with wet age-related macular degeneration (wet AMD). Vascular endothelial growth factor, or VEGF, is a signaling molecule that helps maintain blood vessels in the eye and other organs, but its overabundance in wet AMD patients can lead to overgrowth of vessels that causes vision loss. Though reducing VEGF signaling with anti-VEGF therapies has positive effects in many patients, some individuals continue to experience vision deterioration during treatment.

Researchers characterize Ssb chaperone protein for the first time

For 20 years, researchers have tried to find out why the chaperone Ssb is the only member of the widespread Hsp70-chaperone family that is able to bind directly to the ribosome. This question has now been answered at the University of Konstanz. The researchers identified two regions within the Ssb chaperone that mediate direct contact with the ribosome and thus support the function of Ssb. "We can demonstrate that Ssb interacts with the ribosome mainly via positively charged amino acids", says Professor Elke Deuerling, whose team discovered the binding sites of Ssb. The results were published on 5 December 2016 in Nature Communications.

How plants manage excess solar energy

Life on earth largely depends on the conversion of light energy into chemical energy through photosynthesis by plants. However, absorption of excess sunlight can damage the complex machinery responsible for this process. Researchers from the University of Geneva (UNIGE), Switzerland, have discovered how Chlamydomonas reinhardtii, a mobile single-cell alga, activates the protection of its photosynthetic machinery. Their study, published in the journal PNAS, indicates that the receptors (UVR8) that detect ultraviolet rays induce the activation of a safety valve that allows dissipation of excess energy as heat. A second protective role is thus attributed to these receptors, whose ability to induce the production of an anti-UV 'sunscreen' had already been shown by the Geneva team.
