Animal bones found at bottom of Hoyo Negro shed light on the

first_imgA team of researchers from the U.S. and Mexico has found bone skeletons at the bottom of the Hoyo Negro cave that show that some animals thought to have existed only in South America also existed in Mexico. In their paper published in the journal Biology Letters, the group describes their recovery and study of multiple skeletons retrieved from the floor of the Hoyo Negro cave and what they learned from them.

The Hoyo Negro cave is located on the eastern coast of the Yucatán Peninsula in Mexico. Back in 2007, researchers discovered that the cave was a treasure trove of bones from ancient animals dating back as far as 30,000 years ago—they also found two human skeletons. Thousands of years ago, the cave was completely dry, and it had an opening at the top through which unsuspecting animals fell 200 feet to their deaths. Since that time, melting glaciers filled part of the cave with water, which served to preserve the bones. Over the past 12 years, researchers have unearthed a host of skeletons. In this new effort, the researchers report on a trove of skeletons they recovered and studied.The researchers report that they found one human skeleton among the bones, which was dated to approximately 12,000 years ago, providing evidence that humans existed during the time of the ground sloths. The other human skeleton found in 2007 dated back to approximately 13,000 years ago, and is one of the oldest human skeletons ever found in the Western hemisphere.Also among the skeletons were the bones of a creature called Protocyon troglodytes, which resembled a wolf, and a short-faced bear. The bear skeleton was notable because it represents a species that is believed to be the largest ever to roam the Earth. The wolf and bear were also notable because both are believed never to have made it out of South America as part of the Great American Biotic Interchange–the time period after a land bridge joined North and South America (approximately 3 million years ago), allowing animals from both sides passage to the other.

Majerhat bridge cavein Preliminary report today

first_imgKolkata: The preliminary report of the high-power committee headed by Chief Secretary Malay De in connection with the Majerhat bridge caving-in incident will be submitted to Chief Minister Mamata Banerjee on Friday.The state government had constituted the committee to probe the incident and ascertain the exact reason behind the same. The committee comprising top officials of departments including the state Irrigation department, the state Public Works Department, Urban Development and Municipal Affairs department, the Public Health Engineering department and senior police officers held their first meeting on September 7 and its report was scheduled to be submitted within seven days.According to sources, the Chief Secretary is going to submit the preliminary report to the Chief Minister on Friday. It may be mentioned that the final report in this connection that will contain the “detailed” technical explanation leading to the caving-in of the bridge will take some more time to get ready.Three probable reasons have come up as the main cause behind the caving-in of the bridge. The issue of “heavy vibration due to the Metro work that was going on just adjacent to the caved-in portion of the bridge” has come up as a “strong reason.” Though the Rail Vikas Nigam Limited (RVNL) had claimed that “there was no relation with the Metro work and the collapse of the bridge”, a question was raised as to how could the authority come to a conclusion so fast within such a short span of time without any inquiry. It may be mentioned that the vibration issue had also come up in the first meeting of the committee.Besides, the issue related to the vibration caused by the Metro work; the matter of timely repair work of the bridge has also been discussed as a potent reason behind the incident that could also probably get reflected in the preliminary report. Moreover, the matter of heavy load on the upper surface of the bridge has been attributed as another reason as the road was repaired without removing the previously existing tar surface of the bridge.At the same time, the state Public Works Department (PWD) is taking all necessary steps to complete construction of the alternate road at the earliest. There will be a discussion with Railway authorities and the Chief Secretary in connection with setting up of a level-crossing near the railway tracks at Majerhat which is required for the alternate road. The Railway authorities have brought to the notice of the PWD engineers that many goods trains pass through Majerhat and further discussion is needed in connection with construction of the alternate pathway.last_img read more

BJP distorting history to create rift among masses Mamata

first_imgCooch Behar (WB): West Bengal Chief Minister Mamata Banerjee Tuesday accused the BJP of trying to “distort” the country’s history to create a rift among the masses on religious lines. India’s history and culture do not promote “sectarianism or bigotry”, she asserted while addressing a public programme here. “Those trying to distort our secular history should know that the people of Bengal will neither encourage nor allow divisive politics,” the chief minister said. Also Read – Rain batters Kolkata, cripples normal life Banerjee also lashed out at the BJP-led government in Assam and the Centre for leaving out names of 40 lakh people from the ‘complete draft’ of the National Register of Citizens (NRC). “In Assam, they (BJP) are trying to drive out 40 lakh people, including Bengalis, by omitting their names from the NRC draft. “There had been reports of suicides by people who found their names missing from the draft. I wonder what will their counterpart (BJP Bengal unit) here will have to say about this” she asked. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed Drawing parallels between the NRC exercise and exodus of Bihari migrants from Gujarat, Banerjee said both the BJP-ruled states are trying to divide people on the basis of caste, creed, race and religion. “While they are driving away Bengalis in Assam, they are also ousting Biharis from Gujarat.The Constitution of our country teaches us to treat everybody equally. We cannot differentiate between people on the basis of caste, creed and religion,” she said. The rape of a 14-month-old girl in Gujarat’s Sabarkantha district on September 28 and the subsequent arrest of a labourer from Bihar for the crime led to sporadic incidents of violence against Hindi-speaking people in the western state. More than 60,000 Hindi-speaking migrant labourers have fled the state. The Trinamool Congress (TMC) supremo alleged that the BJP had no regard for Gandhian principles. “Let us not forget Mahatma Gandhi’s principles. Gandhiji had observed fast at the Beleghata area of Kolkata to stop religious riots.Let us not allow those who want to change the history of the country, the history of Gandhiji, to succeed,” she appealed to the masses. Talking about distribution of land right documents in Cooch Behar, Banerjee claimed her government was working hard to give beneficiaries their due. Bangladesh and India exchanged 162 “adversely held” enclaves on Aug 1, 2015, at the stroke of midnight, ending one of the world’s most complex border disputes that had lingered on for seven decades. A total of 111 Indian enclaves, spread across 17,160 acres, became a part of Bangladesh territory and similarly, 51 Bangladeshi enclaves, covering 7,110 acres, joined India. All Indian enclaves were located in Cooch Behar. The enclave residents were allowed to either reside at their present location or move to the other country. The chief minister, while chairing an administrative meeting Monday, had asked the district officials to speed up the process of handing over land documents to enclave dwellers. If necessary, an ordinance would be issued to speed up the process, she had said. Slamming the Centre for allegedly spending more on advertisements, less on development programmes, Banerjee said the NDA government should take a cue about running projects and schemes from Bengal. “In Bengal, we have allocated nearly 6,000 crores for various development schemes… Our schemes have been universally acclaimed. You (BJP) should learn from us,” she said.last_img read more

Woman tortured for dowry dies of burn injuries

first_imgKolkata: A woman in Narendrapur in South 24-Parganas died of burn injuries after she allegedly set herself on fire. It is further alleged the woman took the extreme step as her husband and in-laws tortured her for dowry.According to sources, Santoshi Pramanik of Nepalgunge at Bishnupur in South 24-Parganas got married to Uttam Pramanik of Bonhooghly in Narendrapur approximately seven years ago.

Ballygunge 1990 all about love longing and mystery

first_imgSet three decades back in the bylanes of Kolkata’s Ballygunge, a theatre production by director Atul Satya Koushik explores, along with love, longing and loss, a genre under-done in Hindi drama – that of mystery and suspense. The 85-minute play ‘Ballygunge 1990’ attracts with its lead actor, ‘Crime Patrol’ anchor Annup Sonii, but retains audience engagement with its storyline and execution. Annup describes the Hindi play as the “revenge story” of a relationship where his character abandons a lover for ambition and returns years later after failing. Directed without intervals or even a blackout, the play escalates from a seemingly simple love story, to one of crimes, and ultimately vindication. Also Read – Add new books to your shelfHowever, in the Hindi dramatic landscape, one would find plenty of socio-political and mythological themes, but not many thrillers. Koushik himself has debuted in this genre with ‘Ballygunge 1990’, popularly explained as the revenge story of a failed relationship. “Suspense and thriller is not a genre much explored in Indian theatre, especially Hindi theatre. So, I thought of a play which has love in its foreground, undertones of suspense and mystery in the background. The characters are not real, but emotions are real and come from what I see around,” Koushik said. The romantic-thriller play has been produced by the Film and Theatre Society. And, it was staged in the Capital on July 21, 2019.last_img read more

The Latest in FlatPanel Displays

first_img We don’t have to preach the cause of the flat-panel monitor anymore. Everybody knows they’re affordable, space-saving and easy on the eyes. The question now is, Which LCD monitor should you buy?The 17 and 19-inch flat panels are practically budget models these days. The real action is happening in the slightly larger 20 and 21-inch screens. They’re still affordable, and they’re not so enormous that they dwarf your desk or make you feel like you’re sitting in the front row at the local cineplex. We rounded up a good selection of 20-inch LCDs suitable for general business use. These models tend to skim in at prices under $400 and, in some cases, under $300.There are certain features you can expect to find in a solid 20-inch business monitor. Look for both digital and analog inputs. That means that you’ll be able to hook up to both older analog equipped desktops as well as newer machines with digital outputs. A three-year warranty is standard. Widescreen designs are incredibly popular right now, mirroring a trend in notebook displays. If you plan on viewing video and wide spreadsheets or tiling multiple windows, this is a nice design feature. Most monitors in this range are VESA-compliant to be wall-mounted if you choose.You will run into a host of technical specs such as contrast ratio, dot pitch, response time and brightness. Technophiles, especially those who frequently work with graphics or multimedia applications, will want to spend some time com-paring and contrasting these. Response time in particular has been getting a lot of attention. Faster generally is better–a 10-millisecond response time should give a better video performance than a 20-ms response time. Both the ViewSonic VG2030wm and the Hewlett-Packard LP2045w boast 5-ms response times. But the best measure is still personal experience. If you have the opportunity to try a monitor before you buy, put it through its paces with a DVD and note whether the video has any digital noise or ghosting. Look for smooth, clean video performance.Extra features can make the difference when you’re shopping for a moni-tor. The $399 (all prices street) Dell UltraSharp 2007WFP, for example, comes with a built-in four-port USB 2.0 hub, picture-in-picture capabilities and the ability to double as an HD-compatible TV. The $329 ViewSonic VG2030wm comes stocked with integrated speakers.When it comes to budget 20-inch LCD monitors, you might have to make some trade-offs to get that ultra-affordable price point. Pivot is usually the first feature to go. If you need to work with spreadsheets and other long documents, then you’ll want to look for pivot capabilities and pay the few extra dollars. General adjustability can make a big difference when it comes to viewing comfort. That includes height adjustment, swivel and tilt. The Westinghouse Digital LCM-20v5 hits a very attractive sub $300 price point with a fast 8-ms response time, but it is somewhat limited in adjustability.It might be tempting to shop for the biggest monitor you can afford, but your best bet may be to invest in two smaller monitors. A dual 20-inch moni-tor setup won’t stress your budget too much, but it will boost your productivity and give you tons of viewing space for multiple programs and windows. There are plenty of different LCD manufacturers to look into. Also check out offerings from Envision, Gateway, LaCie, Lenovo, Planar and Sony. All those options mean you have a variety of 20, 21, and even 22-inch flat-panel monitors to choose from. Just match up your budget to the feature set you desire.

Bash Bug Could Be Bigger Than Heartbleed

first_img Register Now » Almost six months after the Heartbleed bug was discovered, another security flaw has been uncovered. And the “Bash bug” has the potential to be even more dangerous.The 25-year-old security vulnerability is based in the “Bash shell,” a program that controls the command prompt and is used for many simple tasks on your computer, like opening an application. The “Bash” or “Shellshock” bug affects computers running Unix and Linux devices, as well as hardware running Mac OS X, reports CNET.The bug is triggered when a hacker adds extra code to lines of Bash code, allowing him or her to potentially take control of your device and access your private information. The hack is reportedly low complexity, which could be catastrophic when paired with the wide range of devices in danger. The National Vulnerability Database ranks the bug a 10 out of 10 in terms of severity, so it really can’t get much worse than this.Related: Another Hack: Jimmy John’s Is the Latest Chain to Suffer a Data BreachSince Bash is so widely used in operating systems, a huge volume of devices are likely to be vulnerable to the bug. Especially at risk are “Internet-of-Things” devices, which often use software built from web-enabled bash scripts and are less likely to be patched than a laptop. Without patching something like your home security system or a light bulb that is connected to your network, the bug can allow hackers to access everything behind your firewall.Also at risk are older devices. Since the security flaw has been around for a quarter of a century, there will be many vulnerable devices that likely won’t be patched, putting users’ entire networks at risk.Users have been advised to patch their operating systems ASAP. Keep an eye out for available updates that fix the vulnerability, and download as soon as they are available. Related: 4 Ways to Protect Yourself From the ‘Heartbleed’ Bug Growing a business sometimes requires thinking outside the box. 2 min readcenter_img September 25, 2014 Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Globallast_img read more
