  Title Differential Drift in Menarcheal Age in Blind and Sighted Girls Type Journal Article
  Year 2018 Publication Gynaecology and Perinatology Abbreviated Journal  
  Volume 2 Issue 4 Pages 333-339  
  Keywords Human Health  
  Abstract Our survey data show that menarcheal age, both in sighted and blind girls has drifted towards younger years compared to 50 years back, however, in sighted girls it has gone further down compared to blind girls. In this paper we have explained the reasons, why it is so? For the comparison sake we were very careful to select sighted and blind girls from the same geographical region, socio-economical and education status and food habits. Taking into consideration, our earlier hypothesis, “blind women and breast cancer”, here also we propose that only the photo regulatory system for hormonal axis is responsible for differential lowering of Menarcheal age in sighted and blind girls, since all other regulatory factors are same in both the groups.

  Title Melatonin suppression and sleepiness in children exposed to blue-enriched white LED lighting at night Type Journal Article
  Year 2018 Publication Physiological Reports Abbreviated Journal  
  Volume 6 Issue 24 Pages  
  Keywords Human Health  
  Abstract Light-induced melatonin suppression in children is reported to be more sensitive to white light at night than that in adults; however, it is unclear whether it depends on spectral distribution of lighting. In this study, we investigated the effects of different color temperatures of LED lighting on children’s melatonin secretion during the night. Twenty-two healthy children (8.9  2.2 years old) and 20 adults (41.7  4.4 years old) participated in this

study. A between-subjects design with four combinations, including two age

groups (adults and children) and the two color temperature conditions

(3000 K and 6200 K), was used. The experiment was conducted for two consecutive nights. On the first night, saliva samples were collected every hour

under a dim light condition (<30 lx). On the second night, the participants

were exposed to either color temperature condition. Melatonin suppression in

children was greater than that in adults at both 3000 K and 6200 K condition.

The 6200 K condition resulted in greater melatonin suppression than did the

3000 K condition in children (P < 0.05) but not in adults. Subjective sleepiness in children exposed to 6200 K light was significantly lower than that in

children exposed to 3000 K light. In children, blue-enriched LED lighting has

a greater impact on melatonin suppression and it inhibits the increase in

sleepiness during night. Light with a low color temperature is recommended

at night, particularly for children’s sleep and circadian rhythm.

  Title Artificial light at night alters life history in a nocturnal orb-web spider Type Journal Article
  Year 2018 Publication PeerJ Abbreviated Journal  
  Volume 6 Issue Pages e5599  
  Keywords Animals  
  Abstract The prevalence of artificial light at night (ALAN) is increasing rapidly around the world. The potential physiological costs of this night lighting are often evident in life history shifts. We investigated the effects of chronic night-time exposure to ecologically relevant levels of LED lighting on the life history traits of the nocturnal Australian garden orb-web spider (Eriophora biapicata). We reared spiders under a 12-h day and either a 12-h natural darkness (∼0 lux) or a 12-h dim light (∼20 lux) night and assessed juvenile development, growth and mortality, and adult reproductive success and survival. We found that exposure to ALAN accelerated juvenile development, resulting in spiders progressing through fewer moults, and maturing earlier and at a smaller size. There was a significant increase in daily juvenile mortality for spiders reared under 20 lux, but the earlier maturation resulted in a comparable number of 0 lux and 20 lux spiders reaching maturity. Exposure to ALAN also considerably reduced the number of eggs produced by females, and this was largely associated with ALAN-induced reductions in body size. Despite previous observations of increased fitness for some orb-web spiders in urban areas and near night lighting, it appears that exposure to artificial night lighting may lead to considerable developmental costs. Future research will need to consider the detrimental effects of ALAN combined with foraging benefits when studying nocturnal insectivores that forage around artificial lights.

  Title How Much Should We Trust the Dictator's GDP Estimates? Type Journal Article
  Year 2018 Publication Abbreviated Journal SSRN  
  Volume Issue Pages  
  Keywords Economics; Remote Sensing  
  Abstract I study the manipulation of GDP statistics in weak and non-democracies. I show that the elasticity of official GDP figures to nighttime lights is systematically larger in more authoritarian regimes. This autocracy gradient in the night-lights elasticity of GDP cannot be explained by differences in a wide range of factors that may affect the mapping of night lights to GDP, such as economic structure, statistical capacity, rates of urbanization or electrification. The gradient is larger when there is a stronger incentive to exaggerate economic performance (years of low growth, before elections or after becoming ineligible for foreign aid) and is only present for GDP sub-components that rely on government information and have low third-party verification. The results indicate that yearly GDP growth rates are inflated by a factor of between 1.15 and 1.3 in the most authoritarian regimes. Correcting for manipulation substantially changes our understanding of comparative economic performance at the turn of the XXI century.

  Title Color polarization vision mediates the strength of an evolutionary trap Type Journal Article
  Year 2018 Publication Wiley Evolutionary Applications Abbreviated Journal  
  Volume In press Issue Pages  
  Keywords Animals  
  Abstract Evolutionary traps are scenarios in which animals are fooled by rapidly changing conditions into preferring poor-quality resources over those that better improve survival and reproductive success. The maladaptive attraction of aquatic insects to artificial sources of horizontally polarized light (e.g., glass buildings, asphalt roads) has become a first model system by which scientists can investigate the behavioral mechanisms that cause traps to occur. We employ this field-based system to experimentally investigate (a) in which portion(s) of the spectrum are polarizationally water-imitating reflectors attractive to nocturnal terrestrial and aquatics insects, and (b) which modern lamp types result in greater attraction in this typical kind of nocturnal polarized light pollution. We found that most aquatic taxa exhibited preferences for lamps based upon their color spectra, most having lowest preference for lamps emitting blue and red light. Yet, despite previously established preference for higher degrees of polarization of reflected light, most aquatic insect families were attracted to traps based upon their unpolarized spectrum. Chironomid midges, alone, showed a preference for the color of lamplight in both the horizontally polarized and unpolarized spectra indicating only this family has evolved to use light in this color range as a source of information to guide its nocturnal habitat selection. These results demonstrate that the color of artificial lighting can exacerbate or reduce its attractiveness to aquatic insects, but that the strength of attractiveness of nocturnal evolutionary traps, and so their demographic consequences, is primarily driven by unpolarized light pollution. This focuses management attention on limiting broad-spectrum light pollution, as well as its intentional deployment to attract insects back to natural habitats.
