• Scientists identify hundreds of infected cells at different points of initial entry

  • New technology lights up location of first cells to be infected
  • Discovery will enable scientists to develop more effective vaccine
  • 'We see the chink in the armor of the virus' and can attack it early to stop it

    CHICAGO --- Finding the vulnerable points where HIV enters the female reproductive tract is like searching for needles in a haystack. But Northwestern Medicine scientists have solved that challenge by creating a glowing map of the very first cells to be infected with a HIV-like virus.

  • What if a map of the brain could help us decode people's inner thoughts?

    Scientists at the University of California, Berkeley, have taken a step in that direction by building a "semantic atlas" that shows in vivid colors and multiple dimensions how the human brain organizes language. The atlas identifies brain areas that respond to words that have similar meanings.

    The findings, to be published April 28, 2016 in the journal Nature, are based on a brain imaging study that recorded neural activity while study volunteers listened to stories from the "Moth Radio Hour." They show that at least one-third of the brain's cerebral cortex, including areas dedicated to high-level cognition, is involved in language processing.

    Brown fat cells can burn fat to generate heat. University of Bonn researchers have discovered a new method to measure the activity of brown fat cells in humans and mice. The researchers showed that microRNA-92a can be used as an indirect measure for the activity of energy consuming brown fat cells. They showed that a small blood sample was sufficient. Results were published in Nature Communications, a well-known scientific journal.

    People who want to lose weight often encounter boundaries: No matter what diet they try, the pounds won't drop. Being overweight and obese can have severe health consequences, and has shown to increase a person's chance of developing type-2-diabetes or cardiovascular diseases.

    A computer algorithm that can tell whether you are happy or sad, angry or expressing almost any other emotion would be a boon to the games industry. New research published in the International Journal of Computational Vision and Robotics describes such a system that is almost 99 percent accurate.

    Hyung-Il Choi of the School of Media, at Soongsil University, in Seoul, Korea, working with Nhan Thi Cao and An Hoa Ton-That of Vietnam National University, in Ho Chi Minh City, explain that capturing the emotions of players could be used in interactive games for various purposes, such as transferring the player's emotions to his or her avatar, or activating suitable actions to communicate with other players in various scenarios including educational applications.

    Boulder, Colo., USA: Every day, all around the world, millions of people contemplate a very simple question with a very complex answer: which wine? In this month's issue of GSA Today, Gregory Retallack (University of Oregon) and Scott Burns (Portland State University) examine the link between the taste of wine and soil properties.

    In the world of chemistry, one minus one almost always equals zero.

    Young gay and bisexual men under the age of 26 are six times more likely to attempt suicide or self-harm compared to men in that group aged over 45, and twice as likely to be depressed or anxious, according to a paper in the Journal of Public Health.

    As anyone who has visited the London Science Museum’s current exhibition will know, Leonardo da Vinci is famed as an artist, mathematician, inventor, writer … the list goes on.

    He was a figure who did not see disciplines as a checkerboard of independent black and white tiles, but a vibrant palette of color ready to be combined harmoniously and gracefully.

    Today, the polymath may seem like a relic of the past.

    New research from Denmark, Canada and the US involving more than 300,000 individuals suggests that patients do not need to check their cholesterol levels on an empty stomach. So far fasting has been required before cholesterol and triglyceride measurement in all countries except Denmark, where non-fasting blood sampling has been used since 2009.

    Coral reefs face many threats. Ocean acidification, algal takeover caused by overfishing and exploding populations of harmful microbes all jeopardize the health of the world's most productive and diverse marine ecosystems.

    The reefs are not defenseless, however. Like humans, they have a type of immune system that helps protect them. A new study published today in the Proceedings of the Royal Society B has found that one particular molecule found in reef ecosystems plays a similar immunological role in corals as it does in humans. From an evolutionary standpoint, this suggests the molecule's immune function dates back at least 550 million years.
