UC Irvine Cherry Picks which Pseudoscience to Embrace

ACSH - 34 min 27 sec ago

Last month, we were among many scientifically minded groups that were critical of UC Irvine's decision to accept a $200 Million gift from Susan and Henry Samueli, a couple who have deep pockets and even deeper beliefs in the power of alternative medicine.

A Mea Culpa Regarding Nutritional Research

ACSH - 1 hour 41 min ago

The misuse of meta-analysis begins with the differing methodology, populations, and comparisons that are frequently present in nutritional research. The authors explain their concerns and recommendations.

Focus on Staying Active, Not 'Feeling Old'

ACSH - 1 hour 44 min ago

If one thing's for certain, it's that there's never enough money to take care of all the needs of older adults. That holds true on the local, state and federal level, and costs, as they always have, only go up.

While there's no way to completely avoid the costs associated with the social and medical needs of adults as they age, there is an effective way to substantially reduce them by shortening the period in one's life when they're needed.

And that way is staying physically active – in whatever way – for as long as possible.

'Grazing' Eating Pattern Associated with Greater Obesity Risk in Australian Women

ACSH - 3 hours 47 min ago

Does it make a difference to your body weight or weight loss attempts whether you eat 3 meals per day or just graze on mini-meals throughout the day? Some new data from Australia suggests that for women, at least, grazers run a bigger risk of being overweight or obese.

'Chem Guevarra?' -An 'Anarchist' Wants To Help You Make Your Own Rx Drugs. Pfft.

ACSH - 7 hours 6 min ago

Thanks to the 1970s there was the Ford Pinto and Nehru jackets. The 1980s brought us pet rocks and the mullet. We can thank the 1990s for body piercing and tattoos. Since then we've been treated to house flipping, speed dating, Honey Boo Boo, and gluten-free everything. Pretty dumb, no? Not when compared to making your own prescription drugs at home. That's *really* dumb. And real. Sort of.

New analysis suggests that preserving rare species is vital to tropical forests

Eurekalert - 14 hours 31 min ago
The world's tropical forests are in 'a critical state' in which the extinction of rare tree species could be a tipping point, according to an international team of scientists who have developed an analytical method to map their biodiversity.

Three-quarters of the total insect population lost in protected nature reserves

Eurekalert - 14 hours 31 min ago
Since 1989, in 63 nature reserves in Germany the total biomass of flying insects has decreased by more than 75 percent. This decrease has long been suspected but has turned out to be more severe than previously thought. Ecologists from Radboud University together with German and English colleagues published these findings in the scientific journal PLOS ONE on Oct. 18.

New study predicts worldwide change in shallow reef ecosystems as waters warm

Eurekalert - 14 hours 31 min ago
A new study based on the first global survey of marine life by scuba divers has provided fresh insights into how climate change is affecting the distribution of marine life.The research published in the journal Science Advances predicts that as the oceans warm fish -- which appear to be superior predators in warm water -- will extend their ranges away from the equator and cause a decline in the diversity of invertebrates such as crabs, lobsters, sea urchins and whelks.

Mating induces sexual inhibition in female jumping spiders

Eurekalert - 14 hours 31 min ago
After mating for the first time, most females of an Australian jumping spider are unreceptive to courtship by other males, and this sexual inhibition is immediate and often lasts for the rest of their lives, according to a study published Oct. 18, 2017, in the open-access journal PLOS ONE by Vivian Mendez from Macquarie University, Australia, and colleagues.

A study led by the University of Pennsylvania School of Nursing's Diane Spatz, Ph.D., RN-BC, FAAN, the Helen M. Shearer Term Professor of Nutrition, has found that delayed lactogenesis was more prevalent among women who were obese pre-pregnancy and that excessive gestational weight gain was also associated with a delay in lactogenesis II. The study has been published in the Journal of Human Lactation.

Rapid environmental change makes species more vulnerable to extinction

Eurekalert - 14 hours 31 min ago
Interactions between species play a key role in shaping biodiversity. A team of researchers including members of UZH has now shown that the coevolution of species that are embedded in complex networks of interactions is not only influenced directly by their partners but also indirectly by other species. This slows down the ability of complex communities to adapt to environmental change. Rapid climate changes are therefore likely to increase species' risk of becoming extinct.

Understanding the coevolving web of life as a network

Eurekalert - 14 hours 31 min ago
Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have mutualistic interactions with multiple partners, leading to complex networks of interacting species. In a new study, a group of ecologists and evolutionary biologists from five universities has attempted to understand how species coevolve within large webs of mutualistic species.

At tremendous precision, the proton and antiproton still seem identical

Eurekalert - 14 hours 31 min ago
Using a novel two-particle measurement method, a group of researchers measured the magnetic moment of the antiproton at a precision 350 times higher than any previous measurement. The result, published in Nature, shows that the magnetic moments of the proton and antiproton are tremendously close, meaning that so-called CPT asymmetry -- a key factor in the lack of antimatter -- must be very small if it exists at all.
