Study finds no gender discrimination when leaders use confident language
People tend to listen to big talkers, whether they are women or men. Still, more women prefer not to use assertive language, according to a new study. Participants in an experiment more often followed advice of people using assertive ''cheap talk,'' statements that cannot be verified as true. (Example: ''I have extremely strong problem-solving skills.'') They followed advice regardless of advice giver's gender but thought others would be less likely to follow female leaders' advice.

A (pollen-free) sigh of relief for Japan: The genetics of male sterility in cedar trees
Pollen from Cryptomeria japonica, or Japanese cedar, is widely known to cause allergies. But, male-sterile trees are known to be devoid of pollen. Now, researchers from the Forestry and Forest Products Research Institute, Japan, have studied the genetic variations in the male sterility gene (MS1) in these trees. This can help in selectively breeding male-sterile plants to counter the discomfort caused by pollen allergies and overcome the need to stay indoors during the pollen season. (2021-02-17)

'Sex, lasers and male competition:' fruit flies win genetic race with rivals

These shrimplike crustaceans are the fastest snappers in the sea
The snapping claws of male amphipods--tiny, shrimplike crustaceans--are among the fastest and most energetic of any life on Earth. Researchers reporting in the journal Current Biology on February 8 find that the crustaceans can repeatedly close their claws in less than 0.01% of a second, generating high-energy water jets and audible pops. The snapping claws are so fast, they almost defy the laws of physics. (2021-02-08)

Clients of female sex workers should be targeted for HIV prevention and treatment in South Africa

Eavesdropping marmosets understood other monkeys' conversations - and they judged
Captive marmosets that listened in on recorded vocal interactions between other monkeys appeared to understand what they overheard - and formed judgements about one of the interlocutors as a result, according to behavioral analyses and thermal measurements that corresponded with the marmosets' emotional states. The findings suggest that the eavesdropping monkeys. (2021-02-03)

Why do psychiatric drugs help some, but not others? Study offers clues
New University of Colorado Boulder research shows that a key protein in the brain called AKT may function differently in males than females. The study also offers a closer look at where, precisely, in the brain things may go wrong with it, marking an important step toward more targeted and less harmful therapies. (2021-02-01)

Traffic noise makes mating crickets less picky
New research has found that the mating behaviour of crickets is significantly affected by traffic noise and other man-made sounds. When man-made noise pollution was present, the females didn't take into account the courtship song of the male crickets during mating. As the courtship song is energetically costly and provides crucial information about the health of the male, this could affect long-term population viability as females could choose less suitable mates. (2021-02-01)

Size matters: How the size of a male's weapons affects its anti-predator tactics
When males have to fight for reproductive rights, having larger weapons such as horns gives them an edge. However, this can also limit their mobility, making them more vulnerable to predators. In a recent study, scientists from Japan proved, for the first time, that males of a species adopt different anti-predator tactics--tonic immobility or escape--based on the size of their weapons, opening doors to a better understanding of the evolution of animal behaviors.

Three mental health conditions contribute to violent offenses, WCU study finds
Western Carolina University researchers find a disproportionate number of inmates with violent offenses suffer from post-traumatic stress disorder, panic disorder and alcohol use disorder, and published their findings in the Journal of Criminal Psychology. (2021-01-27)

No overall difference in concussion recovery time for male and female college athletes
Researchers found female and male collegiate athletes take approximately the same amount of time to recover from a concussion, with subtle differences in recovery time depending on the type of sports being played and the division level of the sport. The findings suggest that equity in access to sports medical care among college athletes may be contributing to these similar outcomes. (2021-01-26)

Competition among human females likely contributed to concealed ovulation
Humans are among the few species that lack overt physical indicators of female fertility. One explanation for concealed ovulation in human females is that hiding fertility from males helps females secure resources from males for raising children. A new model developed by a team of evolutionary scientists casts doubt on this idea, showing that females might have evolved to conceal ovulation from one another, not from males. (2021-01-25)

Association of obstructive sleep apnea with risk of male infertility
A large health insurance database in Taiwan was used to investigate whether obstructive sleep apnea is a risk factor in male infertility and if treatment for sleep apnea is associated with risk. (2021-01-21)

General health checkups may detect early signs of Parkinson's disease
A research team led by Nagoya University in Japan has found that blood pressure, the hematocrit, and serum cholesterol levels change in patients with Parkinson's disease long before the onset of motor symptoms. This finding may pave the way for early diagnosis and treatment of the disease. (2021-01-19)

Prenatal BPA exposure may contribute to the male bias of autism spectrum disorder
Autism has a higher prevalence in males than females. Bisphenol A (BPA) is a common chemical found in plastics, our food, and even the human placenta. Higher prenatal exposure to BPA is thought to increase the risk of autism. Researchers have, for the first time, identified autism candidate genes that may be responsible for the sex-specific effects of BPA. (2021-01-19)

Male butterflies mark their mates with repulsive smell during sex to 'turn off' other suitors
Butterflies have evolved to produce a strongly scented chemical in their genitals that they leave behind after sex to deter other males from pursuing their women - scientists have found. Researchers discovered a chemical made in the sex glands of the males of one species of tropical butterfly is identical to a chemical produced by flowers to attract butterflies. The study published in PLOS Biology today (19 January 2021) identified a gene for the first time. (2021-01-19)

High-ranking male hyenas have better chances with females because they are less "stressed"
Scientists from the Leibniz-IZW have found that interacting with other males is more ''stressful'' for low-ranking than for high-ranking male spotted hyenas. This restricts the time and energy low-ranking males can invest in courting females and is therefore a key factor for lower reproductive success than their high-ranking rivals. This mechanism seems to be more important in determining the number and quality of offspring than physical traits such as attractiveness and fighting ability. (2021-01-18)

Genital shape key to male flies' sexual success
Having genitals of a certain shape and size gives male flies a major reproductive advantage, new research shows. (2021-01-15)

Higher live birth rates found after transferring fresh rather than frozen embryos...

The team's findings are published in JAMA. (2021-01-12)

Knowledge of cycad branching behavior improves conservation
Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a branch can be used to infer the sex of the tree. (2021-01-11)

Talking like a woman in TED Talks is associated with more popularity
Talking like a woman at online TED Talks is being ''uniquely rewarded'' with more views according to researchers, who say female language style is an ''underappreciated but highly effective tool for social influence''. The researchers wanted to find out which was more predictive of TED Talk impact: a more instrumental and complex male-typical language style or a simpler and more personally engaging female-typical language style. (2020-12-16)

Female language style promotes visibility and influence online
A female-typical language style promotes the popularity of talks in the digital context and turns out to be an underappreciated but highly effective tool for social influence. This was shown by UZH psychologists in an international study in which they analyzed 1,100 TED Talks. (2020-12-16)

Male bats with high testosterone levels have large forearm crusts when females are fertile
Mammalian odors are frequently sexually dimorphic, with males often exhibiting a stronger, or otherwise distinct, odor relative to females, which can be especially useful for nocturnal species with reduced use of vision. Some male bats exhibit intense odors to attract females and reproduce, presumably as a consequence of a high concentration of testosterone. (2020-12-15)

Proportionally more male bosses negative toward depression
A higher proportion of male than of female managers have negative attitudes toward depression, a University of Gothenburg study shows. The more senior the managerial positions, the bigger the share of men with negative attitudes; the same, moreover, applies to women in senior managerial jobs. (2020-12-14)

Vitamin D the clue to more Autism spectrum disorder in boys
Professor Darryl Eyles and Dr Asad Ali from UQ's Queensland Brain Institute found vitamin D deficiency during pregnancy caused an increase in testosterone in the developing brain of male rats. Low vitamin D in mothers is one of the risk factors for Autism spectrum disorder, which is three times as common in boys. (2020-12-11)

The secret behind male ornaments
In many species all over the animal kingdom, males have eye-catching characteristics. Although often impractical, they are beneficial in finding a mate. Scientists have now mapped the genetic bases of such a male ornament in a fish. (2020-12-11)
