Research shows journalists can restore media trust

In a first-of-its-kind study from LSU's Manship School of Mass Communication, researchers discovered journalists can increase media trust by speaking out in defense of their profession, while also doing more fact checking. Contrary to long-established practices in which journalists traditionally ignore attacks against their profession's credibility, Ray Pingree, Doris Westmoreland Darden Professor, and his team found that the combination of fact checking and defending journalism had positive effects, but fact checking alone did not. This combination increased trust in and use of mainstream news, while also increasing confidence in the existence and attainability of facts in politics.

How will the winds of climate change affect migratory birds?

Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers from the Cornell Lab of Ornithology came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years. They also extracted wind data from 28 different climate change projections in the most recent report from the Intergovernmental Panel on Climate Change (IPCC). Their findings were published today in the journal Global Change Biology.

OSIRIS-REx discovers water on asteroid, confirms Bennu as excellent mission target

From August through early December, the OSIRIS-REx spacecraft aimed three of its science instruments toward Bennu and began making the mission's first observations of the asteroid. During this period, the spacecraft traveled the last 1.4 million miles (2.2 million km) of its outbound journey to arrive at a spot 12 miles (19 km) from Bennu on Dec. 3. The science obtained from these initial observations confirmed many of the mission team's ground-based observations of Bennu and revealed several new surprises.

Sprayable gel could help the body fight off cancer after surgery

Many people who are diagnosed with cancer will undergo some type of surgery to treat their disease—almost 95 percent of people with early-diagnosed breast cancer will require surgery and it's often the first line of treatment for people with brain tumors, for example. But despite improvements in surgical techniques over the past decade, the cancer often comes back after the procedure.
