Now selfies can keep
a check on your BP

Apple is continuously working on
improving the health-related features
that it offers with its devices. A new
report revealed that researchers have
discovered a way to measure the blood
pressure without the need for any
external hardware.
Currently, the Apple iPhone or any
other smartphone can measure the blood
pressure of the user. But the user needs
to use an external device to actually
measure the recordings and then send it
to the device. The new report revealed
that the new technology uses a short selfie
video to measure the blood pressure.
What is more interesting is that the
report states that this is accurate about
95% of the time. This could be a lifechanger
as high blood pressure does
not showcase any symptoms.
Researchers at the University of
Toronto in Canada and Hospital of
Hangzhou Normal University in
China posted a proof-of-concept video
showcasing a user measuring his blood
pressure using a short selfie video.
The phone takes about 900 images
in 30 seconds to read the blood
pressure. The research team took the
measurements and then used them to
train a machine-learning algorithm
which gave them over 95% accuracy.

New Delhi: After successfully performing
the fifth and final orbit manoeuvre to
refine its circular path around the moon
on Sunday, Chandrayaan 2 lander,
'Vikram', successfully separated from
the orbiter on Monday.
The Indian Space Research
Organisation (ISRO) confirmed the
development in a tweet.
“The Vikram Lander successfully
separated from Chandrayaan-2 Orbiter
at 1315 hours IST today. The Vikram
Lander is currently located in an orbit
of 119 km x 127 km. The Chandrayaan-2
Orbiter continues to orbit the Moon
in its existing orbit,” ISRO said in a
statement.
The next maneuver is scheduled for
Tuesday between 8:45pm and 9:45pm.
The separation of lander 'Vikram'
from Chandrayaan-2 orbiter was
scheduled between 12:45 pm and 01:45
pm (IST). Following this, there would
be two deorbit manoeuvres of lander
Hyundai makes micro-mobility
easier with folding electric scooter
Mounting to your vehicle for charging.
After unveiling its redesigned 2020
Sonata, Hyundai has returned with its
newest solution for mico-mobility: a
foldable electric scooter prototype.
Weighing at about 17 pounds,
the scooter sees a compact tri-fold
design that can be transformed into a
briefcase-like size, making it highly
portable. Some of its features include
a digital display showing battery life
and a screen that lets you know how
fast you’re going. Thanks to its 10.5 Ah
battery, the electric vehicle can travel up
to 12 mph and also includes articulated
LED lights at the front and rear for
nighttime riding. As a final note, the
scooter mounts to any Hyundai or Kia
vehicle, where it gets charged from the
electricity generated from driving.
Though no further details have been
disclosed about when the new electric
scooter will come out or what it will be
officially called, stay tuned for more
information on its development.
'Vikram' to prepare for its landing in
the south polar region of the moon.
Chandrayaan-2 satellite began its
journey towards the moon, leaving the
earth's orbit in the dark hours, on August
14, after a crucial manoeuvre called
Trans Lunar Insertion (TLI) carried
out by ISRO to place the spacecraft on
"Lunar Transfer Trajectory".
India's Geosynchronous Satellite
Launch Vehicle, GSLV MkIII-M1, had
successfully launched the 3,840-kg
Chandrayaan-2 spacecraft into the
earth's orbit on July 22.
Following the landing, the rover
'Pragyan' will roll out from lander
'Vikram' between 5:30-6:30 am on
September 7 an carry out experiments on
the lunar surface for a period of one lunar
day, which is equal to 14 earth days.
India's second lunar expedition
would shed light on a completely
unexplored section of the Moon, its
South Polar region.
U.S. Citizenship and Immigration
Services (USCIS) officers can now use
fake social media accounts to monitor
immigrants seeking visas, green cards
and citizenship.
The new plan is a policy change from
July that reverses a Homeland Security
Department ban that cited privacy issues.
A statement from USCIS said the agency
will use the fake accounts only “to access
social media content that is publicly
available to all users of the social
media platform,” adding its personnel
will respect users' privacy settings and
won’t "friend" or "follow" users.
USCIS said it doesn’t proactively
monitor social media accounts.
“We use social media information
to investigate an existing request
for immigration benefits, as part of
our background and security check
process,” the statement said. However,
the new USCIS policy may violate
Facebook's and Twitter’s terms of
use, which both prohibit users from
creating fake accounts.
Dave Maass, a senior investigative
researcher for the civil liberties advocacy
group Electronic Frontier Foundation,
said the new policy "undermines our
trust in social media companies and our
ability to communicate and organize
and stay in touch with people."
Hackers cracked Jack Dorsey's Twitter
account using a very simple technique
Twitter founder and CEO Jack Dorsey's
official Twitter account was hacked
on August 30, shocking his followers
as his account spewed racial slurs,
anti-Semitic tweets, and more offensive
content, before all the tweets and
retweets were eventually removed.
According to an initial Twitter
statement, a "security oversight"
by the provider let the hackers gain
control. Twitter's communications
team later clarified that "the phone
number associated with the account
was compromised due to a security
oversight by the mobile provider."
The hack appears to be from the
same group that attacked a number
of account belonging to YouTube
celebrities last week on Twitter,
including beauty vlogger James
Charles, Shane Dawson, and King Bach.
Daniel "Keemstar" Keem, who has
communicated with the hackers on
several occasions, suggested in a tweet
that the phone service provider was to
blame, and alleged that the company
inadvertently allowed hackers to call
in and request a SIM card change on
behalf of the high-profile accounts.
The tactic lines up with Twitter's
explanation for the Dorsey hack,
which the company said was caused by
hackers using a phone number to send
the tweets through text messages.
Such a tactic is often known as "SIM
hacking." It occurs when a hacker
tricks a mobile carrier into transferring
the victim's cellphone number onto a
new phone - one that's owned by the
hackers. The hackers can then use
Twitter's "text-to-tweet" service to
publish tweets on the victim's account.
Wired reported that smartphone
userscan protect themselves from SIM
swapping by adding a passcode to their
carrier account or using a third-party
app - such as Google Authenticator and
Authy- for two-factor authentication.
