(Carnegie Mellon University) Intelligent tutoring systems have been shown to be effective in helping to teach certain subjects, such as algebra or grammar, but creating these computerized systems is difficult and laborious. Now, researchers at Carnegie Mellon University have shown they can rapidly build them by, in effect, teaching the computer to teach.

(Louisiana State University Health Sciences Center) A study conducted at LSU Health New Orleans has shown for the first time that chronic exposure to inhaled nicotine alone increases blood pressure in both the body's general circulation and in the lungs that can lead to pulmonary hypertension. The study also found that nicotine-induced pulmonary hypertension is accompanied by changes in the size, shape and function (remodeling) of the blood vessels in the lung and the right lower chamber of the heart.

(University of Cambridge) Parents should not feel pressured to make their young children undertake structured learning or achieve specific tasks, particularly during lockdown. A new study of children under the age of two has found that parents who take a more flexible approach to their child's learning can - for children who were easy babies - minimise behavioural problems during toddlerhood.

(Elsevier) Children looking for health information online could end up more prone to obesity. A new study in the Journal of Nutrition Education and Behavior, published by Elsevier, shows a lack of digital health literacy can lead children to misinterpret portions, adopt recommendations intended for adults, or take guidance from noncredible sources.

The Agriculture, Fisheries & Conservation Department today said genetic sequencing tests are being carried out on the pet dog of a confirmed COVID-19 patient which could reveal if the virus has mutated or not.

The department's Assistant Director (Inspection & Quarantine) Dr Thomas Sit told a press briefing this afternoon that the coronavirus is what is known as an RNA virus which eventually mutates.

“That is why the University of Hong Kong School of Public Health needs to do a genetic analysis to compare this dog’s genetic sequencing to the virus isolated from the patient so that they can compare. So if it is totally identical, then there is no mutation. The testing is still ongoing.”

Dr Sit reiterated that international experts agreed that the dog has a low level of infection, despite its blood tests not being ready yet.

“From the first sample to our last sample tested, it has already (been) six days. The dog’s nasal or oral mechanism, their secretion they should have - if contaminated - they should have a way to clean the virus, it would not stay for that long if it was just a contamination.

“I think it will take at least five or seven days for the blood results because it is not an easy test, it is not a quick test. We need to grow a virus and then neutralise the serum, so it takes some time.”

He added that it was too early to say whether animal-to-animal transmission was a possibility.

“At this stage, we do not have enough data to have a 100% answer as to whether it is infectious to other dogs or not. But if the dog’s owner is positive, it is better to take precautionary measures to prevent onward transmission.”

Dr Sit also advised dog owners to wash their hands, wear gloves and try to stop their dogs from licking their surroundings to prevent the virus from spreading further.

The maximum monthly rental subsidy for each recycler under the One-off Rental Support Scheme will be increased from $25,000 to $37,500, the Environmental Protection Department announced today.

To help the recycling industry cope with the current economic situation and operational difficulties due to the COVID-19 epidemic, the Recycling Fund has allocated $50 million in additional funds to raise the scheme’s subsidy level.

The fund has now earmarked up to $250 million in total funding to fight the virus and help the recycling industry ride out difficult times.

On April 15, the Advisory Committee on Recycling Fund agreed to strengthen support under the scheme by increasing the rental assistance from 50% to 75% for the subsidy period from April to September.

The maximum monthly rental subsidy for each recycler will be increased to $37,500, while the maximum total rental subsidy for the 12 months will be increased from $300,000 to $375,000.

The scheme was launched last year to benefit about 500 street-corner recycling shops and 400 recycling sites.

In the face of current economic difficulties, the fund announced in February an extension of the subsidy period from six months to 12 months, lasting until September.     

As of April 9, the scheme has approved 103 applications, involving subsidies of more than $20 million.

The application deadline for the scheme is September 30. Enquiries can be made to 2788 5658 or via email.

Seventy-year-old Theresa Chan suffers from joint degeneration, which is why she needs a walking stick.

“My joints are severely abraded. They are painful when I walk or stand. My doctor suggested I replace some joints with implants, but I don't want surgery,” she said.

Smart seniors

Interested in how gerontechnology can help improve the quality of life for older adults, Ms Chan joined the Gerontechnology Practitioner Training Course under Lingnan University’s Gerontechnology & Smart Ageing Project.

The course targets elderly people and caregivers. It introduces them to devices that help seniors get around with ease and live more independent lives.

Ms Chan was impressed by a smart walking stick that is equipped with senior-worthy features like a flashlight with an adjustable safety light, a siren for emergency use and a radio.

“I am grateful for the course because I can learn more about gerontechnology in my free time. After class, I can share my knowledge with others who have no idea about this new technology. It is modern and I want to keep up with the times and progress,” she said.

Youth opportunities

Gerontechnology has also opened up career opportunities for young people.

Cecilia Auyeung recently graduated from Lingnan University with a major in marketing. Last year she set up a social enterprise called Gatherly. It provides a platform for the elderly to teach other people handicraft skills and helps them to sell their products online.

Ms Auyeung joined the Socialpreneur Incubation Course under the Lingnan University project. It encourages the development of social enterprises in Hong Kong, gerontechnology and marketing. She quickly drew inspiration from other socialpreneurs.

“I discovered that my social enterprise has to change every two years according to market demands. For example, fabric bags are popular among youngsters. While the elderly at Gatherly are equipped with blue-dye techniques, I make use of their skills to create products that match the market situation.”

University contribution

According to the Census & Statistics Department, in 2036, the proportion of the population aged 65 and over is projected to be 31%. To meet the needs of an ageing population, the Government is promoting gerontechnology, which combines gerontology and technology. It focuses on providing effective solutions to increase vitality and quality of life.

The Lingnan University’s three-year project aims to enhance public understanding of gerontechnology and support smart ageing socialpreneurship development. The project also covers studies with the goal of building a database for gerontech products and services as well as social innovation and startups. The overall vision is to offer policy recommendations to the industry and Government.

Lingnan University Asia-Pacific Institute of Ageing Studies Project Manager Chloe Siu said: “Most of the participating students are willing to think out-of-the-box, using their creativity and knowledge learnt from their courses and to echo the needs of the society. We are trying to facilitate different stakeholders and community partners to create a co-working atmosphere.”

The university has also built a 2,000 sq ft Gerontech-X Lab to display over 40 gerontech products catered to healthcare, dining, living and transport. Anyone interested can book an appointment for a free visit from November 28.

Palestinian officials said Friday that Israel is forcing banks in the occupied West Bank to close accounts held by the families of prisoners in Israeli jails to prevent the Palestinian Authority from providing stipends to them. Israel has long objected to the Palestinian Authority's payments to the families of prisoners and those killed in the conflict, including militants, saying it rewards terrorism. The Palestinians view the payments as a social safety net for those living under decades of military occupation.

SAVANNAH—Gregory and Travis McMichael have been arrested and charged with murder and aggravated assault in connection with the February killing of Ahmaud Arbery, the Georgia Bureau of Investigation announced Thursday. According to police, the white father and son, 64 and 34, chased Arbery, a 25-year-old black man, after he ran by Travis McMichael’s home in the Satilla Shores neighborhood of Brunswick on Feb. 23. He was unarmed and jogging at the time. “This is a start towards victory,” Thea Brooks, Arbery’s aunt, told The Daily Beast on Thursday. “This only the beginning though, but this is what we were all hoping for.”The McMichaels said they believed Arbery was a burglar responsible for a series of break-ins in their neighborhood and that they pursued him in their pickup truck while armed with a shotgun and a .357 magnum. The GBI alleges the McMichaels confronted Arbery, and that Travis shot him. A local prosecutor previously indicated a third man, William Bryan, took part in the chase and filmed the incident.‘It’s Murder’: This Shooting of an Unarmed Black Man Is Roiling GeorgiaAt least two shots hit the 25-year-old, the Glynn County Coroner’s Office told The Daily Beast last week.Video that Brooks said depicted her nephew’s death elicited a furious reaction nationwide, and residents of the area protested the initial failure to prosecute a case on Tuesday.“It’s murder. It’s heartbreaking to even look at. The whole city has seen it,” Brooks told The Daily Beast after the video was released this week.The Georgia NAACP echoed her words in a Thursday response to the McMichaels’ arrest: “The murderers of Ahmaud Arbery have been arrested.”Gregory McMichael, a former cop and investigator with a local prosecutor’s office, previously told The Daily Beast he “never would have gone after someone for their color.” He also said the “closest version of the truth” about the incident was captured in a letter effectively clearing him and his son that was written by a prosecutor who recused himself from the case, George Barnhill. McMichael also admitted he had no direct evidence that Arbery was a thief. “But he’s the guy who’s there without permission,” he said from behind the closed front door of his son’s home.The owner of an unfinished home just down the street from Travis McMichael's home, Larry English, told The Daily Beast earlier this week that he had surveillance footage that appeared to show Arbery stopping to look at the foundation of his still-under-construction home. While Gregory McMichael claimed to police that Arbery had been caught on surveillance video, it was not immediately clear what video he was referring to. English told The Daily Beast he had no knowledge of the McMichaels seeing his surveillance footage. McMichael’s ties to law enforcement helped fuel a haze of suspicion around the killing from the beginning. Barnhill was one of two area prosecutors who looked into the incident before recusing themselves. A third prosecutor—District Attorney Tom Durden—sought a GBI probe ahead of the arrests this week.Read more at The Daily Beast.Got a tip?

Russia's GRU military intelligence service appears to have got hold of many emails from Chancellor Angela Merkel's constituency office in a 2015 hack attack on Germany's parliament, Der Spiegel magazine reported on Friday, without citing its sources. A spokesman for the German government had no immediate comment. Der Spiegel said federal criminal police and the federal cyber agency had been able to partially reconstruct the attack and found that two email inboxes from Merkel's office had been targeted.
