For the First Time, Scientists Catch Australian ‘Night Bees’ in Action | Instant News

Before dawn, with enough light to see, James Dorey and his companions went out to find bees.

This may sound like a futile exercise, since most bees sleep rather than forage for food when it’s dark; dim light blurs the colors of the flowers, and the nights result in cooler temperatures.

But at least some bees have bucked the trend. For the first time, Dorey and her team based in Adelaide caught a bee foraging at night in Australia, and it shows that there are more nocturnal bees hiding in the dark.

“We know that bees mostly forage during warm weather – they generally don’t like foraging when it’s cold, wet, dark, too hot,” Dorey, an entomologist at Flinders University, told ScienceAlert.

“Hence, we bee researchers tend to follow a similar work ethic.”

We know that some bees are nocturnal, having evolved to these conditions. So unless scientists search for it in the dark, that means we could potentially miss out on an entire species of night bee.

“It was long thought that some bees might forage at night in Australia, but this is based on fairly indirect data,” Dorey told ScienceAlert.

“Foraging behavior like this has evolved several times [around the world] and some groups of bees have species that at least extend their foraging into the dark, even if they are not foraging in the dark as a full-time show. “

Dorey’s outing to Daintree rainforest – as well as a number of other research sites around far North Queensland – eventually proved useful, with the team reporting foraging for the evening meal of two native bee species: Reepenia bituberculata and Meroglossa gemmata, the latter a kind of masked bee.

This is the first time an Australian bee has been recorded foraging in the dark, and it makes Australia the only place with known low light adaptations. masked bee In the world.

The team goes a step further, learnsClose-up images of 75 specimens from 68 bee species, analyzing characteristics such as eye, head and body type and size – all to determine whether the night bee is undergoing physical changes compared to the bee foraging during the day.

Bees, like most insects, have both compound eyes (those on the side of their heads) and simple or Ocelli’s eyes (three small eyes in the center of the head), which only catch light. Both compound eyes and ocelli are larger in bees that forage in dim light.

“We found that these low light-adapted bees tended to have bigger eyes, as well as being on the larger side for bees,” Dorey told ScienceAlert.

(Dorey et al., Journal of Hymenoptera Research, 2020)

Above: Low light bees, facultative (can forage in both low light and normal light), and diurnal (daytime) bees that show different eye sizes of the ocelli. A and B are Reepenia bituberculata, while E is Meroglossa gemmata.

Big eyes make sense – the bigger your eyes are, the more light you can take in – and researchers suggest that larger bodies could help night bees better regulate their temperature in colder conditions.

The team hopes that the image analysis technique can be used in the future to find other species of night bees, without having to sneak around in the dark hoping to find them.

“We were able to show that it is possible to determine whether a bee can adapt to dim light conditions using only imagery,” Dorey told ScienceAlert.

“It will make it easier for researchers to find these neat, dim light bees in the future.”

With limited research investigating even Australia’s daytime (or diurnal) bee populations, there is still a lot of research to be done – including how these creatures can adapt to a warming future, and it is critical that night bees are not left out.

“It is possible that these bees will be threatened by climate change,” said Dorey ScienceAlert.

“But it’s also possible they will benefit from a warmer climate increasing their area or allowing them to forage for longer periods of time. If the latter is true, then these bees may become more important for pollination services as a diurnal foraging window for bees. become narrower. “

This research has been published in Hymenoptera Research Journal.

FBR is eyeing waste of output to increase additional revenue of Rs15 billion | Instant News

KARACHI: The Federal Revenue Council (FBR) aims to generate up to Rs15 billion in additional sales tax revenue by setting limits on production waste announced by producers, officials said on Saturday.

To prohibit waste and treat it as a sale, FBR has put in place a rule whereby companies’ reported wastage of raw materials equates to average wastage in the sector concerned.

Officials say large entities engage in practices that claim a significant percentage of production wastes and in some cases claim as high as 40 percent.

Through the Finance Law, 2020, new amendments were introduced to the Sales Tax Law, 1990, in which the fixation of waste would be determined by sector.

FBR in a circular issued on August 6, 2020, stated, “The changes were made to remove the discretion of the jury officers and for similar treatment throughout the board regarding allowing / prohibiting input tax credits for input items wasted during normal business processes, as long as the credit exceed the benchmarks / limits set by FBR ”. FBR on October 1, 2020 issued SRO 938 (I) / 2020 to inform the rules for implementing sectoral fixation of waste.

As a rule, the FBR Input-Output Coefficient Organization (IOCO) has been mandated to improve the limits of waste for an economic sector. “Where the level of waste has been corrected and notified by the board [FBR] Under this rule, no registered person has the right to take input tax adjustments with respect to wasted input above and above the limit set and notified by the board, “the guidelines said.

A senior FBR official said at the time of budgeting for the 2020/21 fiscal year policymakers were expecting around Rs12-15 billion in additional revenue by streamlining this process.

FBR has detected a large variant of waste claimed by manufacturing companies in various sectors including tobacco, steel, vegetable oils, food, sugar, cement, pharmaceuticals etc., the official added. He further said the wastage claimed by some industrial issues was well above international benchmarks.

The entire exercise will help FBR reduce the size of the refund, he said.

“Once the benchmark for wastage is set, FBR can add waste to sales and subtract the same amount from the plaintiff’s refund amount,” the official added.

Zeeshan Merchant, President, Karachi Tax Bar Association (KTBA) said that it is almost impossible to compare waste because of the different production environments of different companies in the same sector.

“If FBR sets limits on waste for a particular sector, the implementation stage will be more difficult because companies from the same sector can use machines of different brands, origins and capacities,” he said, adding that such situations led to an increase. in litigation.

Britain’s richest man and Prada owner is eligible to apply for a ‘critical worker’ exemption to NZ for the Copa America | Instant News

The billionaire owner of the international Cup of America team can be considered a “critical worker” in the eyes of the New Zealand Government – which has opened the door for them to apply for border waivers before the 2021 event.

This week, the Ministry of Business, Innovation and Employment (MBIE) indicated that the America’s Cup team could now apply for an exemption for their owners to enter New Zealand under the “other critical workers” category.

This border exclusion category allows Britain’s richest man, Jim Ratcliffe, who owns Ineos Team UK, and owner of Italian luxury fashion house Prada, Patrizio Bertelli, to enter New Zealand.

A spokesman for Luna Rossa’s team Prada Pirelli told the Herald on Sunday that “Mr Bertelli is still considering his travel plans to New Zealand” ahead of the Copa America tournament, which kicks off in Auckland in December.

An Ineos Team England spokesman said: “No decisions have been made regarding the attendance of the three team owners [the primary of whom is Ratcliffe] still.”

Ratcliffe, 67, is worth $ 32 billion and is the founder of the Ineos Chemicals group. He formed a dedicated Ineos Team UK team to compete in the 2021 Copa America, investing $ 215 million to do so.

Bertelli, 74, is worth $ 5 billion and is the executive director of the Prada Group. He has been involved with the Copa America since 1997, when he formed the Prada team to compete at the Auckland event in 2000.

An MBIE spokesperson said the border exclusion category was because the American Cup was a “Government approved event”.

“It is up to individual syndicates whether their ‘other critical worker’ requests include the owner and senior team figures. All requests (and individuals included in the request) are assessed by INZ against the relevant border exclusion criteria.”

The international team competing third was the New York-based American Magic Yacht Club.

A spokesperson said they could not disclose any information about their discussions with MBIE about bringing their team leader to New Zealand.

However, they say some of the American Magicians are already with the team in Auckland.

About a month ago, Oculus Announced reducing its VR headset product portfolio by dropping support for Oculus Go In order to focus more on Oculus Quest and Oculus RiftS. However, there are now new photos that describe the redesigned Oculus Quest, possibly with a new set of lenses, and the release date is not too far away.

In a few photo Post on Twitter Through the mature leaker WalkingCat, we can see footage of what looks like an updated and streamlined Oculus Quest, as well as a title titled “September 15”. Cat while walking There is no clear mention of whether the date represents a formal announcement or release date, If accurate, this means that Oculus may be ready to release a new VR headset in less than two months.

Although WalkingCat’s lens looks a lot like a typical printing press rendering, the equipment in the picture is Very close to another set of leaked photos Posted on Reddit today. Therefore, although we cannot be 100% sure that these photos are legitimate, seeing two different leaking surfaces showing very similar designs increases credibility.

This refurbished Oculus Quest is covered with white plastic and seems to be a smoother and smoother update to the original Quest (announced in the fall of 2018). Scattered on the headset are standard ports, including what looks like a 3.5mm audio jack and USB-C port, as well as elongated vents for Quest’s built-in speakers.

However, what we don’t see in this refreshed Quest is for adjustment Interpupillary distance, usually used to help adjust Focus on users with various facial and eye structures. And, when you combine a lens that lacks an IPD slider with a lens with a slightly different shape, it means that Oculus’ next task may be to modify the optical components, including new lenses, or even upgrade the display.

That is, in addition to white instead of black, the controller shown in the WalkingCat image The appearance is very similar to Quest’s existing controllers, so not all functions on the new Quest may have been fully overhauled.

Unfortunately, we still lack information about the price and availability of the new Quest, and what kind of hardware will power Oculus’ next VR headset. But Oculus has previously stated that it wants “Doubly improve our products for Quest and Rift,” Refurbished the current entry-level VR headset It seems to be a good way to keep promises.

Punjab, KP to oversee JKT | Instant News

Islamabad – Authorities in the federal government have instructed the power corridors of Punjab and Khyber Pakhtunkhewa to closely monitor the political activities of the former strong PTI leader, Jhangir Khan Traeen (JKT) to prevent a political collapse after a forensic audit report on the sugar crisis.

Sources who are aware of developments say that senior level authorities at the Center have assigned this task to Chief Minister Khyber Pakhtunkhewa Mehmood Khan and Punjab Minister of Food Abdul Aleem Khan.

This step was taken after the sugar special inquiry commission in its report accused JKT of committing tax fraud by violating various laws and pledging to oppose the report.

JKT has played a key role in bringing together candidates who can be elected in the 2018 general elections that make PTI in power.

“There is no doubt that JKT still enjoys good relations with those who have given him party tickets and they won their respective seats,” a senior PTI told The Nation on Saturday.

Asking not to be named because of the political sensitivity of this issue, the PTI leader said that JKT could still cause serious setbacks for the party because of connections within the party.

When asked what kind of challenges JKT could pose to PTI leadership, the PTI leader said he could help facilitate the formation of advanced blocs in Punjab and the KPK.

Although JKT has so far avoided making direct political commentary, he has explained to everyone at PITI that he is still at the PTI, which according to party people has warned the PTI of his political ambitions.

They also decided on the possibility to patch between the Prime Minister and JKT. However, despite some JKT efforts not available for his comments.

Last month the inquiry committee headed by FIA Director General Wajid Zia in his report accused JKT and other sugar mill owners of getting the most from government subsidies.

“After leaving these reports, there is no strong lobby that can benefit at the expense of our public,” the prime minister said in a tweet after the first investigation report was published.

Prime Minister Imran Khan has formed a special inquiry commission for sugar to conduct detailed forensic audits of nine companies that are suspected of benefiting from government subsidies for sugar.

The special inquiry commission which was supposed to submit the forensic audit report was given three more weeks due to the Covid-19 pandemic and finally submitted the report on May 21.
