(PhysOrg.com) — In a recent paper posted at arXiv.org and submitted to Astrophysical Journal, Dan Hooper and Jason Steffen, physicists at Fermilab in Illinois, present the theory that cold and dark planets, not heated by a star, could be heated by dark matter. In theory, this dark matter could produce habitable planets outside of what is known as a habitable zone.
© 2018 Phys.org A small team of researchers with the Crop Research Institute and Palacký University, both in the Czech Republic, has rediscovered a plant first (and last) recorded over a century and a half ago. In their paper published in the journal Phytotaxa describing their find, Michal Sochor, Zuzana Egertova, Michal Hrones and Martin Dancak describe the plant, a mycoheterotroph called Thismia neptunis. An orchid that never blooms More information: MICHAL SOCHOR et al. Rediscovery of Thismia neptunis (Thismiaceae) after 151 years, Phytotaxa (2018).

T. neptunis was first discovered back in 1866 by botanist Odoardo Beccari. He drew pictures of it in his notebook. The plant was not seen by other researchers until the team from the Czech Republic came across it last year, and took what are believed to be the only pictures of it ever captured.The plant, the team reports, is small, with a flower just 9 centimeters across. It grows in wet dirt along a river in a rainforest in Matang Massif, Borneo. It is also a member of the mycoheterotrophic family, which means it is not capable of photosynthesis, but instead survives as a parasite. It has no leaves, but its flower is unique, shaped like a bulb with three antennae-looking appendages that stick straight up into the air. The bulb itself is described as pale-colored with red stripes and an opening on top. The bulb is suspended on a whitish smooth stem. The plant’s features are similar to others in the genus Thismia, which collectively have been given the unofficial name of fairy lanterns. The team reports that they found dead flies inside one of the plants, suggesting a means for pollination. They noted also that Beccari did a remarkably good job of capturing what the plant looks like in his drawings.Prior research on other mycoheterotrophs has shown that they are tropical plants with more structure underground than above—the flower is, of course, used as a means of reproduction. They survive by absorbing fluids from underground fungi and typically only bloom for a few weeks at a time over the course of a year. They do not always bloom, though, which suggests the find by the Czech team was quite lucky.Beccarri, the researchers note, also discovered two other plant species in the area—they are hoping to rediscover those as well.

AB de Villiers hit a rapid 64 to lift South Africa to a competitive total of 283 for seven in the series-deciding third and final one-day international against New Zealand on Kingsmead on Wednesday.The South African captain was the only batsman who made batting look easy against a steady New Zealand bowling attack on a pitch which offered the New Zealand bowlers good bounce and some sideways movement.De Villiers hurried to a half-century off 38 balls before being bowled by Doug Bracewell after a 48-ball innings which included eight fours and a six. Also Read – A league of his own!When De Villiers was on 19 he reached 8000 runs in one- day internationals in his 182nd innings – the fastest to the milestone. The previous record was held by Sourav Ganguly of India, who took 200 innings.After a poor batting performance in the second match in Potchefstroom, where they were bowled out for 204, South Africa fulfilled their objective of making a solid start as Morne van Wyk (58) and Hashim Amla (44) put on 89 for the first wicket.But the scoring rate was languishing until De Villiers and David Miller (36) put on 86 off 65 balls for the fourth wicket. Left-arm opening bowler Ben Wheeler took three wickets but conceded 71 runs, while medium-pacer Grant Elliott bowled ten overs in an unbroken spell and took two for 41.
The Embassy of Hungary and the Hungarian Information and Cultural Centre in association with the Sree Arts commemorated the Day of Hungarian Culture with a bouquet of events on January 30. It touched the fields of art, music and dance and literature. In the presence of dignitaries and eminent artists, ‘Dreams of the mind’ presented by two contemporary Hungarian artists Csilla Babinszky and Zsuzsa Moizer commenced. The chief guests for the evening included Mr Gyula Petho, Ambassador of Hungary, Dr Alka Pande, Curator and Art Consultant, Visual Arts Gallery and Dr Alka Raghuvanshi, eminent artist, curator and critic with Mr Sandeep Marwah, Mr Vijendra Sharma and Mr Jitendra Padam Jain as the Guests of Honour and Mr Qazi Raghib as the special guest. Also Read – Add new books to your shelfThe two Hungarian contemporary artists Csilla Babinszky and Zsuzsa Moizer applied traditional themes and forms through a unique personal discourse by using a contemporary approach and spirit. Babinszky’s large-scale, mixed technique paper series “Strange Angels” explores the female being in the universal context, inspired by and at the same time questioning the beauty and its major appearance. These collage-like drawings use several instruments like gold gouache and silver graphite, aquarelle, colored pencils, acrylic. She says, “Art for me is connection. Staying connected with the genuine question’s conceptual and visual outcome.” Also Read – Over 2 hours screen time daily will make your kids impulsiveMoizer’s intimate human figures and zoomorphic creatures are exploring the human existence, fragility and evanescence within the natural environment and social context. The new series of water colour paintings are realistic forms of nature towards lyrical compositions, which refers to a subjective landscape instead of a real world. The best approach to her characteristically tender images is probably through the topics of women’s search for identity, and gender roles.
