Close bonds with the opposite sex can have non-romantic benefits. And not just for people, but for our primate cousins, too.
Drawing on 35 years of data, a new study of more than 540 baboons in Amboseli National Park in Kenya finds that male baboons that have close female friends have higher rates of survival than those who don’t.
Researchers have often assumed that when a male is friendlier to certain females, it’s for the reproductive perks: to better protect his offspring, or to boost his chances of mating with her. But the new study points to an additional potential benefit: female friends may help him live a longer life.
The team’s findings will appear Sept. 21 in a special issue of the journal Philosophical Transactions of the Royal Society B.
It’s well known that people who have close friendships are more likely to live a long life than
Intolerances to chemicals, foods and drugs impact 8%-33% of individuals, studies suggest, yet few people are screened for it at their doctors’ offices.
To address this and increase awareness of chemical intolerance, researchers at The University of Texas Health Science Center at San Antonio (UT Health San Antonio) developed and validated a three-question, yes-or-no survey that primary care providers, allergists, dermatologists and other specialists can incorporate into patient visits. The survey, called the Brief Environmental Exposure and Sensitivity Inventory, or BREESI, can also be used by researchers and patient groups, and for epidemiological studies in exposed populations.
Sept. 16 in the journal PLOS ONE, the researchers reported that the BREESI accurately predicts scores on a comprehensive 50-question survey called the Quick Environmental Exposure and Sensitivity Inventory (QEESI). The QEESI, which the UT Health San Antonio group introduced online in 2014, is available at no charge to patients and clinicians.
In a paper published today in Nature Astronomy, researchers report the first ever clear images of nanojets — bright thin lights that travel perpendicular to the magnetic structures in the solar atmosphere, called the corona — in a process that reveals the existence of one of the potential coronal heating candidates: nanoflares.
In pursuit of understanding why the Sun’s atmosphere is so much hotter than the surface, and to help differentiate between a host of theories about what causes this heating, researchers turn to NASA’s Interface Region Imaging Spectrograph (IRIS) mission. IRIS was finely tuned with a high-resolution imager to zoom in on specific hard-to-see events on the Sun.
Nanoflares are small explosions on the Sun — but they are difficult to spot. They are very fast and tiny, meaning they are hard to pick out against the bright surface of the Sun. On April 3, 2014, during what’s
