Scientists made the discovery while studying Colombians who are genetically predisposed to get Alzheimer’s early
Tuesday marks the 29th annual World AIDS Day, dedicated to raising awareness about the AIDS pandemic and commemorating those who have died from illnesses related to the disease.
While many may know that AIDS is caused by HIV and is potentially life-threatening, many don’t know much else about it.
As the video above, produced by AsapScience, explains, HIV is a retrovirus transmitted through the blood, most often via sexual contact. It is extremely difficult to target with medication because of its high mutation rate.
Science has come a long way and people with HIV who have access to anti-retroviral therapy can live long, full lives. HIV and AIDS, however, remains a global health issue, which affects over 35 million people.
Educating ourselves and understanding HIV and AIDS is a big part of preventing transmission of the HI virus, as well as treating and curing the disease.

Despite the media scare stories, trigger warnings are not widely used by college professors across the country, according to a survey released in full on Tuesday. They’re not even widely demanded by students. And when they are used, the warnings address both liberal and conservative concerns.
The nonscientific survey, conducted by the National Coalition Against Censorship, is the first of its kind to gather data on the actual use of trigger warnings in college classes. The conclusion: While professors are fretting about the possibility, there is “no crisis.”
Trigger warnings advise readers that the content ahead addresses sensitive subjects, such as child abuse, rape and racist violence, that may evoke personal trauma. The warnings, which became popular on blogs over the past decade, are typically placed at the beginning of reading material or stated verbally. A debate has emerged in recent years about their use in the university setting.
The Atlantic has written repeatedly about the “spread” of demands for trigger warnings. Jill Filipovic at The Guardian has said “we’ve gone too far” with trigger warnings, essentially echoing Peggy Noonan’s critiques in The Wall Street Journal. Even WikiLeaks has attacked them. The American Association of University Professors last year issued a statement condemning trigger warnings as a “threat to academic freedom.”
Yet, as the NCAC survey shows, the fears stoked by some in the media have gone well beyond the on-campus reality.
The Huffington Post first reported the statistics from the survey in June, showing that virtually no college required the use of trigger warnings. The full release of the results on Tuesday included testimony from some of the 800-plus current teaching professors who were surveyed. The project —> Read More
On a recent fossil-hunting trip to the island, researchers stumbled across a cache of dinosaur footprints in what was once a lagoon.
A large team of American scientists has found evidence of blood vessel-like structures in the fossil of Brachylophosaurus canadensis, a mid-sized duck-billed dinosaur that lived in what is now Montana around 80 million years ago. Research team leader Dr Tim Cleland of the University of Texas at Austin and his colleagues demineralized a fragment of [...] —> Read More
Its Big Cat Week on NatGeo Wild, and one of the headliner films is Cougars Undercover, a dramatic film following the lives of two mountain lion families in northwest Wyoming. The stars of the film are F51 and F61, adult female mountain lions studied by Panthera’s Teton Cougar Project, an ongoing work addressing diverse ecological questions that began in late 2000. F51’s mothering style is described as “like a hippie mother, just providing lots of love, but not necessarily all the sustenance they need [her kittens],” while “super mum” F61 comes across as a sleek, stern, and extremely competent provider. Read a review of the film in the Wall Street Journal, or watch a clip from the film here.
We, at Panthera, are thrilled for the opportunity to highlight the challenges wild mountain lions face in rugged western landscapes. They are a species that receive little conservation attention, and a species often maligned and misunderstood. We hope the film begins to paint a new picture of what mountain lions really are. You can still catch the film in the coming week if you missed its original debut—air times can be found here.
The film was a collaborative effort between the BBC, NatGeo Wild and Panthera, but in the end, it was professional filmmakers that told the story. And they did a wonderful job of it, relaying the intensity of mountain lion lives, and even some of the melodrama of the characters that follow them. Nevertheless, there are several additional points we would like to provide, as background information for viewers. Several of these are born of questions we have received since the release of the film.
A new study found that watching sexual reality television stimulated adolescents aged 13-17 to produce and share sexual images of themselves on social media. Similarly, for both boys and girls, sexual self-presentation on social media led to more frequent watching of sexual reality TV. The full study results are reported in Cyberpsychology, Behavior, and Social Networking. —> Read More

U.S. Supreme Court Justice Louis Brandeis, in a 1932 opinion, wrote that a state could be a ‘laboratory’ for policy, and ‘try novel social and economic experiments’ on its own. We have since turned those words into today’s common political phrase that the 50 U.S. states are ‘laboratories of democracy.’ —> Read More
